So many quick connectors. It depends on your scope of application. How can I answer that question?! The quick joint can be divided into: quick joint for air, quick joint for oxygen fuel gas, quick joint for gas liquid, quick joint for oil pressure, quick joint for inert gas, quick joint for cooling water temperature oil, and quick joint for semiconductor.
1, the type of fluid, temperature (please select the type of fluid, temperature of the body material and sealing material of the quick joint) according to the fluid, the suitable body material, sealing material is different. For example, quick couplings are air. Steel is recommended, water is selected brass or stainless steel.
2, the pressure of the liquid (please select a quick joint suitable for the pressure resistance of the fluid pressure) The pressure of the fluid is also the key to the selection of the quick joint. The quick joint for oil pressure is a series of 5.0Mpa(51kgf/cm²)-68.6Mpa(700kgf/cm²), corresponding to the pressure characteristics, the structure of the quick joint is also different.
3, the structure of the automatic switching valve (please select a quick connector for the valve structure suitable for pipe use) For the structure of the valve, there are two switch type, one way switch type and two open. In addition to the two switch modes, there is fluid flowing out of the distribution tube during separation. So pay attention.
4. The use environment of the quick joint (please select the quick joint with the structure and material suitable for the use environment) combined with the humidity conditions of the use environment, the condition of dust, and the use environment such as easy corrosion, to consider the type of the selected quick joint, the body material, and the sealing material.
5, the shape and size of the installation (please order the product after determining the final shape and size) Please determine the type and material of the quick connector, and specify the assembly shape and size corresponding to the characteristics of the pipe. Please note that size is dependent on fluid flow.
