電動(dòng)截止閥

[

截止閥的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運(yùn)動(dòng)。閥桿的運(yùn)動(dòng)形式，（通用名稱：暗桿），也有升降旋轉(zhuǎn)桿式，（通用名稱：明桿）截止閥是指關(guān)閉件（閥瓣）沿閥座中心線移動(dòng)的閥門。 根據(jù)閥瓣的這種移動(dòng)形式，閥座通口的變化是與閥瓣行程成正比例關(guān)系。由于該類閥門的閥桿開啟或關(guān)閉行程相對(duì)較短，而且具有非常可靠的切斷功能，又由于閥座通口的變化與閥瓣的行程成正比例關(guān)系，非常適合于對(duì)流量的調(diào)節(jié)。因此，這種類型的閥門非常適合作為切斷或調(diào)節(jié)以及節(jié)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
