法蘭式截止閥
美標(biāo)法蘭式截止閥 公稱通徑:DN50-DN400, 壓力等級(jí):150LBS~1500LBS, 材質(zhì):WCB,WCC,LCB,LCC,WC6,WC9,CF8,CF8M等 截止閥是在管道中用來調(diào)節(jié)流量的閥門,不僅開閉過程中密封面之間摩擦力小,比較耐用,而且結(jié)構(gòu)簡(jiǎn)單,制造容易,維修方便. 采用標(biāo)準(zhǔn): 設(shè)計(jì)制造:鑄鋼截止閥按照BS 1873 and ASME B16.34 檢驗(yàn)和試驗(yàn):API 598 法蘭連接:ASME B16.5 對(duì)焊端:ASME B16.25 結(jié)構(gòu)長(zhǎng)度:ASME B16.10 溫壓等級(jí):ASME B16.34 操作形式: 一般情況下采用手輪驅(qū)動(dòng)或者齒輪傳動(dòng)方法,可根據(jù)用戶需要采用鏈輪傳動(dòng)或者電動(dòng)裝置。 |
閥體和閥蓋連接形式:
Class150~Class900采用拴接閥蓋;Class1500~Class2500采用自壓密封式閥蓋。
閥蓋墊片形式:
Class150截止閥采用不銹鋼石墨復(fù)合墊片;Class300截止閥采用不銹鋼石墨纏繞墊片;Class600截止閥可用不銹鋼石墨纏繞墊片也可采用金屬環(huán)墊片;Class900截止閥可采用金屬環(huán)墊片;Class1500~Class2500截止閥采用自密封金屬環(huán)。
填料密封:
通常采用柔性石墨作為填料材料,可根據(jù)用戶需求提供PTFE或者復(fù)合填料材料。填料與填料函接觸的表面粗糙3.2μm,可以保證閥桿與填料接觸面接合緊密但是旋轉(zhuǎn)自如,經(jīng)過精密的機(jī)械加工的閥桿密封面粗糙度0.8μm可以保證閥桿可靠的密封。
截止閥結(jié)構(gòu)特點(diǎn):
拴接閥蓋,明桿支架和升降式閥桿金屬密封面。
