力士樂(lè)REXROTH截止閥R901093910線(xiàn)路連接

動(dòng)作原理：

截止閥的啟閉件是塞形的閥瓣，密封面呈平面

或錐面，閥瓣沿閥座的中心線(xiàn)作直線(xiàn)運(yùn)動(dòng)。閥

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)

桿的運(yùn)動(dòng)形式，（通用名稱(chēng)：暗桿），也有升

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(lèi)閥門(mén)的閥

降旋轉(zhuǎn)桿式，（通用名稱(chēng)：明桿）截止閥是指

關(guān)閉件（閥瓣）沿閥座中心線(xiàn)移動(dòng)的閥門(mén)。

桿開(kāi)啟或關(guān)閉行程相對(duì)較短，而且具有非常可

節(jié)。因此，這種類(lèi)型的截流截止閥閥門(mén)非常適

合作為切斷或調(diào)節(jié)以及節(jié)流用。

性能介紹：

閘閥的密封面有一定的自密封能力，它的閥芯

啟和關(guān)閉時(shí)閥芯和閥座密封面始終接觸并相互

磨擦，因而密封面容易磨損，特別是在閥門(mén)處

靠介質(zhì)壓力緊緊地與閥座密封面接觸，達(dá)到嚴(yán)

死。所以，高溫、高壓楔形閘閥，在結(jié)構(gòu)上都

采取了一定的防止閥芯卡死的措施。閘閥在開(kāi)

密不漏。楔形閘閥的閥芯斜度一般為3~6度，

當(dāng)關(guān)閉過(guò)量或溫度變化較大的閥芯容易卡

于接近關(guān)閉狀態(tài)時(shí)，閥芯前后壓差很大，密封

面磨損就更為嚴(yán)重。
