高压截止阀的启闭件是塞形的阀瓣,密封面呈平面或锥面,阀瓣沿流体的中心线作直线运动。阀杆的运动形式,有升降杆式(阀杆升降,手轮不升降),也有升降旋转杆式(手轮与阀杆一起旋转升降,螺母设在阀体上)。截止阀只适用于全开和全关,不允许作调节和节流。

保不住,基本上就是高压截止阀发生内漏了。
第三,高压截止阀或者泄压阀坏了,即发生了内泄漏或者外泄露。
Third, high pressure cut-off valve and pressure relief valve is broken, the inside outside leakage or leakage happened.
只要阀门关闭效果良好,保压时,高压截止阀关闭,后端压力容积变小,压力增大。
As long as the valve closure effect is good, when the pressure, high pressure cut-off valve is closed, the back-end pressure volume smaller, pressure.
