YDK43H液壓快關(guān)止回蝶閥主要安裝于汽輪機(jī)抽汽管路，高爐煤氣或焦?fàn)t煤氣余壓發(fā)電裝置（TRT）供氣管路等高安全等級(jí)系統(tǒng)，作緊急切斷閥用；在系統(tǒng)出現(xiàn)危機(jī)工況時(shí)，在0，3``0，8秒鐘內(nèi)實(shí)施緊急關(guān)閥，實(shí)現(xiàn)管路的可靠截止，有效防止汽機(jī)尾部蒸汽和冷凝水倒灌，保護(hù)汽輪機(jī)組的安全或當(dāng)煤氣管路的壓力下降時(shí)緊急切斷煤氣管路，防止煤氣回火事故發(fā)生。我公司生產(chǎn)的液控快關(guān)閥又分為；全液壓蓄能器型快關(guān)閥及液壓彈簧蓄能型快關(guān)閥。
YDK43H液壓快關(guān)止回蝶閥產(chǎn)品型號(hào)說(shuō)明：

YxK  D  7  ※    4  3 ※  –  ※  ※
閥門(mén)材料：　C 碳鋼 ；P，不銹鋼；I鉻鉬鋼
公稱(chēng)壓力：  單位: kg/㎝2　　
密封材料：　H 不銹鋼，W本體材料
結(jié)構(gòu)形式：　3 三偏心結(jié)構(gòu)(新標(biāo)準(zhǔn))
連接方式：  法蘭連接

P  電氣為PLC智能控制
驅(qū)動(dòng)方式： 液壓傳動(dòng)
                                      產(chǎn)品類(lèi)別：  蝶閥
功能特征：  YxK蓄能快關(guān)；YtK彈簧快關(guān)
產(chǎn)品結(jié)構(gòu)及特點(diǎn)：
  由閥門(mén)本體，傳動(dòng)執(zhí)行機(jī)構(gòu)，液控裝置，電控系統(tǒng)等四大部分組成，其主要結(jié)構(gòu)如下：
1， 電液聯(lián)動(dòng)快關(guān)蝶閥的閥門(mén)本體根據(jù)管路系統(tǒng)不同的壓力溫度等級(jí)要求采用三偏心金屬硬密封蝶閥或彈性金屬硬密封閘閥，這兩種閥門(mén)是目前世界上較為*和流行的閥門(mén)，采用這類(lèi)閥門(mén)可有效密封且啟閉閥門(mén)力矩小，使用壽命長(zhǎng)，維修方便。（詳見(jiàn)三偏心金屬硬密封蝶閥有關(guān)資料）。
2， 電液聯(lián)動(dòng)快關(guān)蝶閥的閥門(mén)材料選用及適用工況
