Explanation of the structural characteristics of the suction check valve

Release Date: December 18, 2019

Structural features of extraction check valve:

1. The sealing surface is welded with Cr13 series stainless steel or cobalt-based hard alloy, which has good wear resistance and stable and reliable sealing performance.

2. The heavy hammer acts on the pin through the extension rod and the fork to balance the heavy moment of the rocker and prevent the occurrence of water hammer. When the medium is flowing forward, it helps to open the valve and keep the valve stable and reduce vibration during operation.

3. When the medium is flowing in the forward direction, the air in the lower chamber of the cylinder is fed with air and interacts with the weight, and the closing flap is in a fully open position in a balanced manner. When the medium flows in reverse, the pressure in the lower cavity of the cylinder piston is quickly released, and the valve flap closes quickly in 0.5 seconds.
