Type 300X slow-closing check valve consists of the main valve, check valve, needle valve, ball valve, micro filter and pressure gauge to form a hydraulic control valve takeover system Using hydraulic automatic operation, the main valve can get the best opening and closing speed. Prevent water hammer and water hammer, so as to achieve the effect of slow closing and silencing. When the valve feeds water from the inlet end, the water enters the main valve control room through the microfilter, needle valve and one-way valve, and then drains downstream through the ball valve. Because the opening of the needle valve is smaller than the opening of the ball valve, that is, the drainage speed of the main valve control room is greater than the water inlet speed, so the pressure in the control room decreases, and the inlet pressure acting on the lower end of the main valve disc opens the main valve to supply water downstream.
