style="text-indent:25px">波紋管截止閥的密封試驗：試驗波紋管截止閥通常是在常溫下以公稱壓力PN進行的，一般是在1.5倍PN壓力下進行的，耐磨波紋管供應商。波紋管截止閥由于有兩個密封副，故需進行雙向密封試驗。試驗時，先將波紋管截止閥的閥門開啟，把通道一端封堵住，壓力從另一端引入，待壓力升高到規(guī)定值時將閥門關(guān)閉，然后將封堵端的壓力逐漸卸去，并進行檢查，耐磨波紋管供應商。另一端也重復上述試驗，耐磨波紋管供應商。波紋管截止閥的另一種試驗方法是在體腔內(nèi)保持試驗壓力，從通道兩端同時檢查閥門的雙密封性。波紋管閘閥的結(jié)構(gòu)長度大于閘閥，同時流體阻力大，長期運行時，密封可靠性不強。耐磨波紋管供應商</p><div
