style="text-indent:25px">常見問題編輯調(diào)節(jié)閥為什么雙密封閥不能當作切斷閥使用？雙座閥閥芯的優(yōu)點是力平衡結(jié)構(gòu)，允許壓差大，而它突出的缺點是兩個密封面不能同時良好接觸，造成泄漏大。如果把它人為地、強制性地用于切斷場合，顯然效果不好，即便為它作了許多改進（如雙密封套筒閥），也是不可取的。調(diào)節(jié)閥為什么雙座閥小開度工作時容易振蕩？對單芯而言，當介質(zhì)是流開型時，閥穩(wěn)定性好；當介質(zhì)是流閉型時，閥的穩(wěn)定性差。雙座閥有兩個閥芯，下閥芯處于流閉，上閥芯處于流開，這樣，在小開度工作時，流閉型的閥芯就容易引起閥的振動，這就是雙座閥不能用于小開度工作的原因所在。烏魯木齊各種進口閥門公司推薦。新疆烏市排污閥采購</p><p

style="text-indent:25px">什么直行程調(diào)節(jié)閥防堵性能差，角行程閥防堵性能好？直行程閥閥芯是垂直節(jié)流，而介質(zhì)是水平流進流出，閥腔內(nèi)流道必然轉(zhuǎn)彎倒拐，使閥的流路變得相當復雜（形狀如倒S型）。這樣，存在許多死區(qū)，為介質(zhì)的沉淀提供了空間，長此以往，造成堵塞。角行程閥節(jié)流的方向就是水平方向，介質(zhì)水平流進，水平流出，容易把不干凈介質(zhì)帶走，同時流路簡單，介質(zhì)沉淀的空間也很少，所以角行程閥防堵性能好。為什么角行程類閥的切斷壓差較大？角行程類閥的切斷壓差較大，是因為介質(zhì)在閥芯或閥板上產(chǎn)生的合力對轉(zhuǎn)動軸產(chǎn)生的力矩非常小，因此，它能承受較大的壓差。新疆烏市排污閥采購</p><p
