Thank you very much!: Selection of check valve for pump outlet check valveGeneral pump station project, for the pump outlet check valve, the following principles should be observed;The outlet check valve shall be used when the diameter of the outlet pipe of the pump is smaller, that is, DN50mm.The pipeline of the pump outlet pipe diameter DN is larger than 50mm, should be used in swing check valves can be installed horizontally or vertically. Swing check valve to rotate around the shaft, the fluid resistance is generally less than the lift check valve, which applies to the larger diameter of the occasion, the installation location restrictions, usually installed in horizontal pipelines, it applies with large caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves for medium and medium duty applications. Large diameter pipeline using single swing check valve, in order to reduce the water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double valve swing check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a fast check valve. Multi disc swing check valve is suitable for large diameter pipeline

Q: Check valve does not automatically check back, how to adjust?: The non-return valve does not automatically check the cause:1, the valve at both ends of the road must be blocked, there is dry ventilated room.
