PVC plastic check valve can be called a one-way valve or a check valve. It allows the flow of the medium itself to drive the valve flap to open and close. It is generally a valve to prevent the medium from flowing back, so it is also called a reverse valve. Check valves, one-way valves, counter-flow valves, etc., are automatic plastic valves. Commonly used one-way valves include spin-down type, swing plate type, ball type and so on. It is mainly used to prevent the backflow of the medium or the discharge of the medium. Usually this kind of valve works automatically. Under the pressure of the medium flowing in one direction, the valve flap can automatically open. If the medium flows in the opposite direction, the pressure and the valve flap will act on the valve seat to cut off the flow. It also includes focusing on different valve methods.
Plastic check valve
PVC plastic check valves are widely used in industry. Generally, in order to prevent fluid from flowing back, plastic check valves are installed on the pipeline, but they are generally used for relatively clean media, some with solid particles and relatively high viscosity media It cannot be used. There are also some points to pay attention to when installing. When installing on the pipeline, pay attention to the direction that the plastic check valve passes and the flow direction of the fluid is the same, and avoid adding pipe joints and other items within the scope of the disc operation. Blocking objects to prevent adverse effects on the valve body. If you want to avoid disc fragmentation, you must use plastic materials to make the disc check valve, which is a plastic check valve. If there is a back flow of the medium, check whether the sealing surface is damaged or impurities are trapped in the pipeline. It is necessary to repair the sealing surface and clean the impurities in time to prevent the back flow of the medium.
Plastic reverse valve plastic check valve
Since the valve body of PVC plastic check valve is relatively light, easy to install, and has strong corrosion resistance, it has a wide range of applications. Therefore, this valve has been widely used in many piping systems, but it is installed and used at the same time. During the process, pay attention to regularly check or repair the valve to ensure that the valve can work normally and avoid affecting the piping system.
