Q:I installed here in the water pump inlet, water pump with a 100 tons of water tank, there are many pumps, long time running, the pump will heat the cylinder, there is no water in the cylinder, the pressure does not go. The water pump is imported. Is the check valve broken or is the installation position wrong?: Is the check valve installed at the inlet or outlet of the pump? Mainly to see whether the water pump suction or press in? There are other factors, such as pressing first class.

Also, how high the pump needs to be played, and the pressure is often determined. The check valve is installed on the water outlet side of the pump. I simple analysis may be the following reasons, need to have a simple to complex one by one investigation, 1, electrical specifications are matching? 2 、 the pump has air intake or air not discharged 3, piping layout is reasonable? 4, check valve installed counter, or check valve did not open, stuck,?

Such as gas regulator.For example, the compressed air regulator has no reverse cut-off function.Regulators in the form of a lot of specific circumstances, specific analysis, only to exceed the body can withstand the pressure, generally not bad.

Q:The difference between slow closed valve and open the valve: The difference is mainly that the opening and closing of the slow closing check valve depend on the external and external forces to perform the slow opening and closing (usually hydraulic cylinder or pneumatic cylinder). The swing check valve is opened and closed by the pressure of the pipe medium to complete the opening and closing (and the pressure of the pipeline).
