The principle of supporting the use of the quick coupling: the quick faucet is also called the quick male coupling, it must be connected to the female joint, that is, the quick coupling is often said to be used together. The common situation is the thread connection mold of the quick faucet. The female head of the upper quick connector, the other end of the quick connector is in the shape of a pagoda, which is used to connect water pipes or iron fluorine pipes, which is convenient to use and can automatically cut off water.

From the water cutoff effect, there are two types: closed and open; the closed can automatically cut off the water. When the quick coupling and the quick nozzle are separated, the water remaining in the water pipe will be automatically sealed and will not flow out, so that the workshop compares It is clean, but it has some drawbacks. It is a closed type. If the water quality of the factory is not good, stains will remain inside after long-term use, which will affect the water flow. Therefore, if the closed type is used, the water should be filtered or the water channel should be cleaned regularly. Open style is better

The type and temperature of the fluid (please select the quick coupling suitable for the type of fluid, temperature of the body material and the sealing material). Depending on the fluid, the suitable body material and sealing material are different. For example, the quick connector is air. It is recommended to be made of steel, or brass or stainless steel if it is water.

The pressure of the liquid (please select a quick coupling suitable for the pressure resistance of the fluid), and the pressure of the fluid is also the key to selecting the quick coupling.

The selection principle of quick coupling: When choosing quick coupling and quick faucet, if it is a better product, the copper surface is relatively smooth, there is no sand hole, and the color is brighter. Of course, there are also those with average quality, depending on your needs. Most of the quick couplings and quick taps are made of copper, of course, some of them are made of stainless steel or carbon steel, which are mainly hydraulic quick couplings. Some quick couplings and quick faucets are also made of iron, and the surface is electroplated, but they are easy to rust, but the cost is relatively low, and the ones that suit you are good. Quick couplings and quick faucets are also made of stainless steel, but the cost is higher than copper, mainly because the production process is complicated and the production speed is slow. When using quick couplings and quick faucets, there should be no debris when the joints and faucets are connected, so as not to affect the service life, and often add some lubricating oil to facilitate the connection.
