300X Slow Control Check Valve

Specifications

Taian is a manufacturer and supplier specializing in supplying 300X-Slow Control Check Valve.The check valve is an intelligent valve that features hydraulic self-control, slow opening and closing, and integrates the functions of check and water hammer elimination. 300X-Slow Control Check Valve is installed at the pump outlet or the end of the pipeline network to prevent backflow when the pump stops and water hammer damage.

Working principle

When the valve is fed from the inlet end, the water enters the main valve control room through the micro-filter, needle valve, check valve, and then drains downstream through the ball valve, Because the opening of the needle valve is less than the opening of the ball valve, that is, the drainage speed of the main valve control room is greater than the inlet speed, so the pressure of the control room is reduced, and the inlet pressure acting on the lower end of the main valve disc opens the main valve to supply water downstream.Pawn pipe When the water supply is stopped, if the downstream water begins to return, pat of the return water enters the main control room through the ball valve, due to the function of the check valve, the return water cannot flow out of the main control room, causing the main control Gradually increase the pressure in the chamber and slowly close the main valve.
