I. Overview of 175H48Y (H) -200 air exhaust check valve :

空排止回阀,主要用于火电厂给水泵出口处。 175H48Y (H) -200 air exhaust check valve is mainly used at the outlet of feed pumps in thermal power plants. Cooperate with the minimum flow recirculation valve of the pump to maintain the safe operation of the system.

Second, 175H48Y (H) -200 air check valve operation principle:


Open the outlet valve and start the feed pump. After the feed water reaches a certain pressure, the valve core will automatically rise and push away from the valve seat, and the feed water will flow out. 片封闭排空口。 At the same time, the spool connecting rod pulls the drain port valve disc to close the drain port. When the feedwater pump flow rate is reduced, the valve core drops, pushing the connecting rod to pull out the drain valve plate, and open the recirculation door to maintain the minimum flow rate of the pump. 阀芯自动下落关闭通道,从而防止高压水锤对给水系统的破坏。 When the pump is stopped, the valve core automatically drops to close the passage, thereby preventing high-pressure water hammer from damaging the water supply system.
