1、特點The characteristics of
截止閥的啟閉件是塞形的閥瓣，密封上面呈平面或海錐面，閥瓣沿閥座的中心線作直線運動。閥桿的運動形式，（通用名稱：暗桿），也有升降旋轉桿式可用于控制空氣、水、蒸汽、各種腐蝕性介質、泥漿、油品、液態(tài)金屬和放射性介質等各種類型流體的流動。因此，這種類型的截流截止閥閥門非常適合作為切斷或調節(jié)以及節(jié)流用。由于該類閥門的閥桿開啟或關閉行程相對較短，而且具有非?？煽康那袛喙δ?，又由于閥座通口的變化與閥瓣的行程成正比例關系，非常適合于對流量的調節(jié)。The globe valve opening and closing is plug valve, sealing the above a plane or cone, disc along the seat of the center line of linear motion. Stem form of exercise, (generic name: non-rising stem), there are also lift rotating bar type can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid flow. Therefore, this type of globe valve valve closure is very suitable for as a cut or adjust and throttling. Due to open or close the valve stem travel relatively short, and very reliable cutting function, and due to the change of his seat and disc stroke proportional relationship, is very suitable for the traffic regulation.
