黄铜截止阀

[简介]：上海瑞普截止阀阀门厂

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，（通用名称：暗杆），也有升降旋转杆式，（通用名称：明杆）截止阀是指关闭件（阀瓣）沿阀座中心线移动的阀门。 根据阀瓣的这种移动形式，阀座通口的变化是与阀瓣行程成正比例关系。由于该类阀门的阀杆开启或关闭行程相对较短，而且具有非常可靠的切断功能，又由于阀座通口的变化与阀瓣的行程成正比例关系，非常适合于对流量的调节。因此，这种类型的阀门非常适合作为切断或调节以及节流用。

[Introduction]:Shanghai Ruipu Globe valves Valve Factory

Valve opening and closing parts are plug-shaped valve, seal appear before the plane or cone, the valve along the centerline of the fluid in a straight line. Stem form of exercise, （generic name: dark bar）, but also lift rotating rod, （common name: the next shot） pieces of cut-off valve is closed （valve） moves along the centerline of the valve seat. According to this form of valve, valve seat and through the mouth of the change is proportional to the valve stroke. As such open or close the valve stem travel relatively short, but very reliable cut-off function, and because changes in the valve seat and through the mouth of the valve stroke is proportional, is ideal for flow adjustment
