闸阀 Gate valve

靠阀板的上下移动，控制阀门开度。阀板像是一道闸门。

The valve opening is controlled by the up and down movement of the valve plate. The valve plate is like a gate.

快速排气阀 Quick exhaust valve

功能说明：

当系统处于正常工作状态时，气体从进气口P进入，经A进入气缸，排气时从A经排气口O排出。

Function Description:

When the system is in normal working condition, gas enters from the air inlet P, enters the cylinder through A, and is discharged from A through the exhaust port O during exhaust.

当系统需要排气时,进气口O处的压力下降或者撤销。密封圈在系统的压力作用下向下移动,排气口打开O打开，系统实现快速排气。

When the system needs to be exhausted, the pressure at the air inlet O drops or is removed. The sealing ring moves downward under the pressure of the system, the exhaust port opens O, and the system realizes rapid exhaust.
