截止阀
Stop valve
截止阀的阀杆轴线与阀座密封面垂直。
阀杆开启或关闭行程相对较短，并具有非常可靠的切断动作， 使得这种阀门非常适合作为介质的切断或调节及节流使用。
1.截止阀的阀瓣一旦处于开启状况，它的阀座和阀瓣密封面之间就不再的接触，并具有非常可靠的切断动作，合得这种阀门非常适合作为介质的切断或调节及节流使用。
2.截止阀一旦处于开启状态，它的阀座和阀瓣密封面之间就不再有接触，因而它的密封面机械磨损较小，由于大部分截止阀的阀座和阀瓣比较容易修理或更换密封元件时无需把整个阀门从管线上拆下来，这对于阀门和管线焊接成一体的场合是很适用的。介质通过此类阀门时的流动方向发生了变化，因此截止阀的流动阻力较高于其它阀门。

Stem axis and sealing surface are vertical.
It takes stem short time to open and close. Stem with reliable cut-off action is suitable for cutting off media and adjusting and throttling.
1. Seat and disc don’t contact when disc is being opened, and with reliably cutting action to make this kind of valve is suitable for cutting of media and adjusting and throttling.
2. Seat and disc don’t contact when globe valve is being opened makes machinery of sealing surface small wear. Seat and disc are convenient to mended and valve is needn’t to remove from pipeline when changing seals that is suitable for valve and pipeline are welded together. Flow direction is change while media crosses through this kind of valve, so flow resistance of this kind valve is much higher than others.
