次往返移動。密封填料函及其他部件連接處不應有滲漏現(xiàn)象。2 .關閉時的泄漏檢查：① 注水法泄漏檢查，對于雙座調節(jié)閥一般可用簡易的注水法檢查泄漏情況。向薄膜氣室輸入信號壓力使調節(jié)閥關閉，成都滑閥式真空泵。向調節(jié)閥進口處注入溫度為室溫的水，在不加壓的情況下另一端應無明顯滴漏現(xiàn)象。② 水壓法泄漏量檢查：向薄膜氣室輸入信號壓力使閥關閉。將溫度為室溫的水，以10kg/cm2恒定壓力按打開閥芯的方向通入調節(jié)閥的一端，成都滑閥式真空泵，用秒表和量杯在另一端測量其泄漏量不應超過允許值。真空閥門應保持清潔并存放在干燥室內。成都滑閥式真空泵</p><div style="width:100%;text-align: center;"><img style="max-width:
