工作原理
本閥門共有三處通孔，可實現換（huàn）向分流或混合（hé）功能，在一定程度上可替代兩通截止閥。閥門在非工作狀態時，由於彈簧力的作用，閥門C端常閉，B端常開；當執行器活塞被（bèi）壓縮氣體作用時，閥門（mén）C端打開，B端關閉。雙作用形式（shì）時（shí），靠壓縮空氣控製閥門開啟或關閉。
The valve has three through holes,which can realize the function of reversing shunt or mixing,and can replace the two-way stop valve to a certain extent.When the valve is in non-working state,the C end of the valve is normally closed and the B end is normally open due to the action of the spring force.When the actuator piston is acted on by compressed gas,the Cend of the valve is opened and the B end is closed.In double- acting form,the valve is opened or closed by compressed air control.
