style="text-indent:25px">什么直行程調節(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，而介質是水平流進流出，閥腔內流道必然轉彎倒拐，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，介質水平流進，水平流出，容易把不干凈介質帶走，同時流路簡單，介質沉淀的空間也很少，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，是因為介質在閥芯或閥板上產生的合力對轉動軸產生的力矩非常小，因此，它能承受較大的壓差。新疆烏市隔膜閥廠家烏魯木齊市各種進口閥門廠家推薦。</p><div
