?閘閥的啟閉件是閘板，閘板的運(yùn)動(dòng)方向與流體方向相垂直，閘閥只能作全開(kāi)和全關(guān),不能作調(diào)節(jié)和節(jié)流。閘板有兩個(gè)密封面,較常用的模式閘板閥的兩個(gè)密封面形成楔形、楔形角隨閥門參數(shù)而異,通常為5°,介質(zhì)溫度不高時(shí)為2°52'。楔式閘閥的閘板可以做成一個(gè)整體，叫做剛性閘板；也可以做成能產(chǎn)生微量變形的閘板,以改善其工藝性,彌補(bǔ)密封面角度在加工過(guò)程中產(chǎn)生的偏差,這種閘板叫做彈性閘板。閘閥關(guān)閉時(shí),密封面可以只依靠介質(zhì)壓力來(lái)密封,即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來(lái)保證密封面的密封，這就是自密封。成都鍛造電站閥電站閘閥在全開(kāi)或全閉時(shí)，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過(guò)時(shí)，不會(huì)引起閥門密封面的侵蝕。</p><div

style="text-indent:25px">電站閘閥開(kāi)啟過(guò)程：1、在關(guān)閉位置，閥體受閥桿的機(jī)械施壓作用，緊壓在閥座上。2、當(dāng)逆時(shí)針轉(zhuǎn)動(dòng)手輪時(shí)，閥桿則反向運(yùn)動(dòng)，其底部角形平面使球體脫開(kāi)閥座。3、閥桿繼續(xù)提升，并與閥桿螺旋槽內(nèi)的導(dǎo)銷相互作用，使球體開(kāi)始無(wú)摩擦地旋轉(zhuǎn)。4、直至到全開(kāi)位置，閥桿提升到極限位置，球體旋轉(zhuǎn)到全開(kāi)位置。關(guān)閉過(guò)程：1、關(guān)閉時(shí)，順時(shí)針旋轉(zhuǎn)手輪，閥桿開(kāi)始下降并使球體離開(kāi)閥座開(kāi)始旋轉(zhuǎn)。2、繼續(xù)旋轉(zhuǎn)手輪，閥桿受到嵌于其上螺旋槽內(nèi)的導(dǎo)銷的作用，使閥桿和閘板同時(shí)旋轉(zhuǎn)90度。3、快要關(guān)閉時(shí)閘體已在與閥座無(wú)接觸的情況下旋轉(zhuǎn)了90度。4、手輪轉(zhuǎn)動(dòng)的后幾圈，閥桿底部的角形平面機(jī)械地楔向壓迫球體，使其緊密地壓在閥座上，達(dá)到完全密封。</p><p style="text-indent:25px">影響閥門密封性能的因素：介質(zhì)的物理性質(zhì)，介質(zhì)物理性質(zhì)對(duì)其密封性產(chǎn)生的影響較大，在電站閥門的運(yùn)用過(guò)程中，其起到的影響不容忽視，其物理性質(zhì)分為三方面包括：溫度、粘度、親水性。氣體粘度小于液體粘度，而氣體滲透力要高于液體的。通過(guò)理論可知，不算飽和蒸汽，壓縮氣體與液體相比較，發(fā)生泄漏的情況更為頻繁，也更易發(fā)生。從理論可知，對(duì)電站閥門密封性的測(cè)試，如果利用氣體將會(huì)得到更加準(zhǔn)確的結(jié)果。而用于氣體的電站閥門則用氣體做試驗(yàn)是必要條件。焊接閘閥的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運(yùn)動(dòng)。</p><div
