截止閥又稱截門閥，屬于強(qiáng)制密封式閥門，所以在閥門關(guān)閉時(shí)，必須向閥瓣施加壓力，以強(qiáng)制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥門時(shí)，操作力所需要克服的阻力，是閥桿和填料的摩擦力與由介質(zhì)的壓力所產(chǎn)生的推力，關(guān)閥門的力比開閥門的力大，所以閥桿的直徑要大，否則會(huì)發(fā)生閥桿頂彎的故障。按連接方式分為三種：法蘭連接、絲扣連接、焊接連接。從自密封的閥門出現(xiàn)后，截止閥的介質(zhì)流向就改由閥瓣上方進(jìn)入閥腔，這時(shí)在介質(zhì)壓力作用下，關(guān)閥門的力小，而開閥門的力大，閥桿的直徑可以相應(yīng)地減少。同時(shí)，在介質(zhì)作用下，這種形式的閥門也較嚴(yán)密。我國閥門“三化給”曾規(guī)定，截止閥的流向，一律采用自上而下。截止閥開啟時(shí)，閥瓣的開啟高度，為公稱直徑的25%～30%時(shí).流量已達(dá)到大，表示閥門已達(dá)全開位置。所以截止閥的全開位置，應(yīng)由閥瓣的行程來決定。

截止閥（stop valve,Globe Valve）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(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)桿式可用于控制空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品、液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動(dòng)。因此，這種類型的截流截止閥閥門非常適合作為切斷或調(diào)節(jié)以及節(jié)流用。由于該類閥門的閥桿開啟或關(guān)閉行程相對較短，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，非常適合于對流量的調(diào)節(jié)。SAUTER M234SF132
