Q:The working principle of the vacuum check valve: A vacuum check valve is a valve that automatically prevents fluid from flowing back. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the exit side, the valve automatically closes under the influence of fluid pressure, gravity and other factors to prevent fluid flow backwards.Vacuum check valve according to the structure, can be divided into lifting check valve, swing check valve and butterfly check valve three.
