style="font-size:16px;">采用縮徑式流道（無論是錐管形非均勻縮徑或均勻縮徑），其優(yōu)點是同一規(guī)格的閥門，可減少閘板的尺寸、啟閉力與力矩；缺點是流阻增加，壓降和能耗增大，所以縮孔不宜太大。對錐管形縮徑來說，閥座的內(nèi)徑與公稱通徑之比，通常取。公稱通徑小于250mm的縮徑閥門，其閥座內(nèi)徑一般比公稱通徑降低一檔；公稱通徑等于或大于300mm的縮徑閥門，其閥座內(nèi)徑一般比公稱通徑降低二檔。流道呈錐管形的即是一種非均勻縮徑，這類閥門入口端的孔徑基本上與公稱通徑相同，然后逐漸縮小，至閥座處縮小。閥關(guān)閉時，密封面可以只依靠介質(zhì)壓力來密封，即只依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強制密封的，即閥門關(guān)閉時，要依靠外力強行將閘板</span><span style="font-size:16px;">壓向閥座，以保證密封面的密封性。</span> </p><p> <span style="font-size:16px;">軟密封閘閥將是供水行業(yè)樂意采用的一種形式。目前國內(nèi)制造的軟密封閘閥口徑達1500mm，但多數(shù)廠家制造的口徑在80-300mm間，國內(nèi)制造工藝上尚有諸多問題。軟密封閘閥的關(guān)鍵部件是襯膠閥板，而襯膠閥板的技術(shù)要求較高，國外也不是所有廠家都能達到的，往往是從質(zhì)量可靠的廠方購進組裝。軟密封閘閥的銅螺母塊是嵌掛在襯膠閥板上方的，類似閘閥的結(jié)構(gòu)，由于螺母塊的活動摩擦容易使閥板的襯膠剝離。國外某公司的軟密封閘閥，銅螺母塊是鑲嵌在襯膠閘板內(nèi)，形成整體，克服了上述缺點，但閥蓋與閥體組合的同心度要求較高。啟閉軟密封閘閥時，千萬不應(yīng)關(guān)閉過死，只要達到止水效果即可，否則不易開啟或襯膠剝離。某閥門廠家，在閥門試壓檢驗時，使用扭力板手來控制關(guān)閉的程度，作為自來水公司的閥門操作人</span><span style="font-size:16px;">員也應(yīng)效仿此種啟閉方法。</span> 閘閥可以分為單閘板和雙閘板兩種。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="固原閘閥廠家供應(yīng),閘閥"
