An irrigation system consists of a specific set of elements, through which water is supplied from the source to the endpoint. The main ones are hoses and fittings. The sleeve is selected based on the material of manufacture. From the best side, a hose connectors for a hose, which is able to perform a reliable and sealed connection of system elements without the use of tools, has proven itself as a connecting element.
Varieties of hose connectors for hoses and pipes
Depending on the location and number of valves, there are three types of hose connectors fittings.
- The first type has a free passage that does not contain a valve.
- The second option is equipped with a valve on one side.
- The third type is equipped with two valves on both sides.
Quick disconnect couplings can have different connector types. Cam-type products are called camlocks. They are able to quickly and easily dock flexible hoses, connect the sleeve to the container. The cam fitting is characterized by increased resistance to vibrations without the use of additional fasteners. This is the ideal quick release for a compressor.
Drylok quick couplings are used to connect flexible connections of the system for pumping dry media. Such a fitting has a lever valve, which opens and closes the line with one push. These quick couplers reduce the likelihood of overpressure in the pipes, which can cause unexpected ruptures.
Important! These hose connectors are used in systems that transport hazardous substances in the form of oil, solvents or acids.
KAMVALOK industrial hose connectors are used to connect the pipelines for the transportation of glue, varnish, paint, and other acids.
Hose quick disconnects can be straight or angled, and there are three- and four-way fittings.
Types of hose connectors elements depending on the operating pressure of the system
Based on the working pressure, there are four types of hose couplings. ISO-A fittings are used to connect the hoses in a low working pressure system. Due to the presence of valves in the form of a cone, the circulation of the medium inside the line is not obstructed.
FIRG water or air hose couplings have a wide range of applications. When closed, the structure has no protruding parts. The valves have a disc design, as a result of which unnecessary resistance is not created in the system. It also eliminates the possibility of air entering the line or fluid leakage.
For a system with a working pressure of 110-300 bar, TGW quick couplings are used. They are equipped with special protective plugs made of plastic and metal to prevent leakage of the working medium. These quick couplings for 1 ”hose and larger diameter products are capable of withstanding impulsive loads and water hammers. For domestic mobile hydraulic tools, it is advisable to use hose connectors devices of the HPA type, designed for an operating pressure of up to 700 bar.
Important! When choosing a quick coupler with a lower power reserve, there is a high probability of a quick failure of the connection, and the use of a quick coupler with a higher power is an economically unjustified solution.
Other quick couplings for hoses
Quick couplings for air hoses are tubular connectors with a one-way valve and a thread (external or internal). Such fittings also differ in the presence of a “herringbone”, which is located on one side, and on the other, there is a coupling.
The herringbone fitting can be welded, double, or non-hex. A hose is attached to it. The fitting is available in steel, brass, copper, or rubber.
The new generation element is the hose connectors air connection with a two-piece pneumatic connector with a special fuse. The fitting is made of metal, and the body is made of composite material, which ensures the comfort of using the fitting and a long period of operation. It is capable of bleeding oxygen when the pneumatic tool is stopped. The lock is turned on with a regular key. Pressing once will release oxygen, and pressing again will disconnect the instrument.
The hose connectors for the gas hose are equipped with a self-locking element in the form of a socket with a check valve and a disconnecting part – a plug. The fitting is connected to the supply hose through a socket, and with a plug – to another element. When disconnected, the line is locked, which does not require pressure relief in the system until the next connection.
Material for manufacture and design of the fitting
hose connectors are made of stainless steel or alloy steel, aluminum, bronze, titanium, other metal alloys, and polymer materials in the form of polypropylene, PVDF, or polyimide. O-rings are rubber-based elastomers, fluoroelastomers, or polypropylene-ethylene materials.
To ensure a long service life, metal fittings are additionally subjected to anti-corrosion treatment with a protective layer by means of nickel plating, chromium plating, galvanizing, or other hard coatings.
Plastic options are mainly used for domestic needs when organizing an irrigation system. It is advisable to use metal products as hose connectors for fuel hoses.
Cam-type quick couplings are available with a wedge retainer or valve. They can be used for joining plastic or metal pipes, flexible conduits. Some fittings are equipped with a special collet clamp.
Fittings are available in a wide range of diameters, lengths, and weights. In terms of cross-section, quick couplings are available for ½ ”hoses and products up to 150 mm. This value should correspond to the diameter of the hose. Hose quick-release ¾ applies to 19 mm hose. A 1 “connector fits 25mm hose and ½” fits 12mm. Non-standard fittings with a diameter of up to 540 mm are produced on an individual order.
What are the best hose connectors
Before choosing a watering hose so as not to bend, you should consider the existing product options. Based on the material of manufacture, there are rubber, silicone sleeves, as well as PVC and thermoplastic elastomer products.
The most popular is the rubber hose. It is able to withstand working pressures over 8 atm. The material retains its properties at temperatures from -30 to 70 ° C, so it can be stored in unheated rooms and used under the influence of ultraviolet rays.
The material withstands the negative effects of the chemical environment, therefore it can be used to transport corrosive liquids. The rubber hose does not deform and has a long service life. The disadvantages of the material include significant weight (due to the multilayer and reinforced equipment of the product).
No less popular are PVC watering hoses. They have a two- or three-layer texture with built-in synthetic fiber reinforcement. Such products are characterized by resistance to temperature extremes, exposure to ultraviolet rays, are not prone to deformation and withstand operating pressures up to 20 bar. Their cost is slightly higher than the price of rubber analogs. Due to their low weight, they are more convenient to use.
Silicone hoses in the form of single or multi-layer hoses are designed for an operating pressure of up to 2 bar, therefore they are used for a gravity irrigation system. Products with synthetic reinforcement can withstand pressures up to 10 bar. This hose is lightweight, which makes it easy to use. He is not prone to the formation of fractures and bends. However, under the influence of the sun, the walls of the product expand, which leads to the formation of microcracks and their quick destruction.
The thermoplastic hose is a versatile product with high technical and operational characteristics. It can withstand temperatures from -50 to +90 ° C. It is characterized by increased elasticity, flexibility, resistance to twisting and exposure to ultraviolet rays, low weight, but high cost, which is justified by a long period of operation.
The main criteria for choosing an irrigation hose
After choosing the material for making the hose, it is worth deciding on its diameter and length. Depending on these criteria, the sleeve can be purchased on a cut or in a bay. The most common are products whose length reaches 15, 20, 25, 35, and 50 m. This parameter is selected based on the size of the section and the method of laying the hose. If you plan to water different beds, add all the lengths. To connect elements of different sizes, you will need to purchase hose connectors couplings. They can be made in the form of a tee, a herringbone, or across.
Important! A large number of garden hose quick couplings will reduce the speed and power of the water flow.
Based on the diameter, the most commonly purchased hoses are ½, ¾, 1, or 1 ½ inch. The value is selected based on the rule that the diameter of the inner hole should be directly proportional to the length of the sleeve. Compliance with this condition is able to ensure a sufficient constant water pressure.
The next criterion is the selection of a product in accordance with the working pressure in the system. This is determined by the wall thickness of the hose. Single-layer products withstand up to 2 Bar, multilayer with reinforcement – 6-10 Bar. The hose must withstand a wide range of temperatures to prevent wall expansion and cracking.
For the convenient operation of the hose, it is worth purchasing a functional device in the form of a coil on which the product is wound. Before using the hose reel, it is important to know a few rules. Before winding up, disconnect the hose from the water supply and allow the water to drain. Methodically rotating the reel, the hose must be cleaned of dirt with a rag.
What are hose connectors for hose and pipes?
Hose connectors are a specific type of fittings that are used to connect two segments of pipes or hoses in a short amount of time without the use of tools. Such elements greatly simplify the process of installing a fluid supply and distribution system. Compressor hose quick couplings are also used.
hose connectors are compact in size, light in weight, which simplifies the installation process of the system. The fittings are made of a material that is highly resistant to corrosion.
Thanks to the special shape of the product, where the stepped design of the components and the presence of O-rings are combined, a tight, reliable connection of two segments of pipes or hoses is carried out. In addition, the geometry of the fittings provides quick and convenient connection and disconnection of the docking, which expands the scope of their use. High-pressure hose couplings are designed to handle special conditions where conventional couplings cannot.
The quick-release couplings can be used many times over a long period. When properly assembled, the systems can operate at positive and negative temperatures. This type of connection is characterized by low cost.
Despite the positive qualities of fittings, hose connectors also have weaknesses. With each connection and disconnection, the products gradually lose their original best properties. Domestic and imported items are different from each other. The first type should be selected according to the inner diameter, and the second – according to the outer diameter.
Characteristics of hose connectors for water and air
hose connectors are purchased as a set, which includes a special coupling, nipple, T-, L-, Y- and X-shaped adapters, threaded adapters, and clamp fittings. The coupling, referred to as the “mother” of the product, consists of a body, clamping retainer, rotary valve, butt and sealing rings, and a connecting adapter. The nipple, which is called the “dad” of the part, consists of a body, a connecting element, a half-turn valve, a sealing ring.
The connection of the two hose elements by means of a quick-release is done without the use of tools. Before connecting two irrigation hoses of the same diameter, press the locking sleeve on the coupling towards the adapter. The sleeve is inserted into the nipple, which is carried out by the release of the clamping balls. Next, the coupling is unclamped, this will create a reliable fixation in the sleeve nipple. After connection, the check valves will open, which will facilitate free movement along with the hoses of the working medium.
Helpful advice! To remove the quick coupler, the above manipulations are performed in the reverse order.
Some models of modern quick couplings are equipped with automation. Before connecting the two irrigation hoses, you must press them together through the fitting.
Areas of use of hose connectors fittings
hose connectors are widely used for domestic needs, namely in irrigation work. The presence of such elements simplifies assembly, while there is no need to turn off the water. Hydraulic hose quick couplings allow you to connect hoses to pumps, sprinklers, and other irrigation items. They are also used for branching networks. For household needs, quite simple plastic products, which are characterized by wide functionality. They usually consist of several elements. Some fittings are equipped with a locking mechanism or an auto-stop option.
Watering hose quick couplings work well with a variety of irrigation attachments. They also protect the hose from kinking. Products made of shock-resistant plastics with a galvanized coating are widely used. They are more comfortable to work with as they are less slippery.
Fittings are widely used in manufacturing workshops for the installation of hydraulic systems. They can be used to lengthen the flexible hose and move the equipment to another location. There are also quick couplings for pneumatic tools. These fittings are made of impact-resistant steel with a protective corrosion layer. They are presented in one piece. When they are docked, the hose is inserted into the device. Inside it is gripped by a carved springy bushing, which creates the airtightness of the liner. To remove the hose, press on the retaining ring.
Important! When choosing hose connectors for a specific area, it must be ensured that the diameters, sizes and values of the working pressure for all elements of the system are matched.
hose connectors have found their application in the installation of special-purpose highways in the metallurgical, chemical, and mining industries. They are often used in the construction of water, rail, or road transport and the assembly of medical equipment.
How to choose the right quick-disconnect hose fitting
hose connectors are presented in a wide variety today. Most of the models are interchangeable. When choosing a hose connectors connection, consider the operating pressure in the system, the diameter of the hose and the size of the nipple, the temperature conditions of the environment during the period of use of the product, and the possibility of mechanical stress.
Helpful advice! When choosing a hose connectors connection, you should have the hose for which it was purchased.
If the connectors are planning to be used for irrigation purposes, then it is enough to buy inexpensive plastic hose connectors couplings or products with galvanized dusting. In this case, the hose connectors can be threaded or push-off. To install the first option, you will need some skills. To simplify the process of arranging the system, it is better to purchase automatic clamps.
If the water flow is to be divided into several hoses, a hose connector for water with a “hitchhiking” function should be preferred, which will shut off the flows to unnecessary hoses with a closing valve.
The guarantee of long-term operation is not necessarily metal hose connectors. Plastic copies can also meet the stated requirements. In this case, the products must be factory-made, manufactured by a well-known company. Handicraft options will quickly deteriorate, although they can be purchased at a low cost.
The quick-detachable connection provides a quick and convenient installation of the water supply system for irrigation events. The versatility of the fitting also allows it to be used in other areas of activity – when arranging air and gas mains, connecting technological transport.
