1、升降貨梯http://m.iyunsun.com/調壓閥支撐措施不到位，如果不加設支撐或者支撐加設不當都可能造成調節閥閥桿與閥座的不同心，造成調壓閥發熱，容易導致差變或使填料泄漏等故障。即使升降貨梯調節閥有固定和支撐措施，也必須定期進行檢查，一般2～3個月檢查一次。
Lift cargo lift control valve support measures are not in place, if you do not add support or support for the improper design may cause the valve stem and valve seat of the valve stem, resulting in heat, easy to lead to poor or leakage of the filler. Even if the lift control valve has a fixed and supporting measures, it must be regularly checked, generally 2 to 3 months to check.

2、升降貨梯安裝時緊固不均勻，人為的某些碰撞給調節閥及其管道造成的應力等。這些應力作用在調節閥及其管線上，很容易造成調壓閥發熱，嚴重時會影響到升降機上調節系統本身，因此，任何時刻都要保證避免或消除應力，把應力導向遠離調節閥的地方。
When the elevator is installed, the fastening is not uniform, and some of the human impact on the adjustment valve and the pipeline caused by the stress, etc.. These stresses acting on the control valve and its pipeline, it is easy to cause the pressure regulating valve fever, serious when will affect the lift adjustment system itself, therefore, any time to ensure that avoid or eliminate stress, the stress direction from the place far from the control valve.

3、升降貨梯http://m.iyunsun.com/調壓閥內有雜物，要經常檢查調節閥連接升降機的管道內有無鐵銹、焊渣、污物等，發現后應及時清除。因為升降貨梯調節閥在關閉時，很小的一塊鐵銹或焊渣就足以破壞研磨得很好的閥座密封面，況且這些污物也會對調節閥閥芯和閥座造成磨損，影響其正常運行。
Elevator goods ladder adjusting pressure valve with debris, should always check the adjusting valve is connected with a lift pipe rust, welding slag, dirt, etc., found should be promptly removed. Because the elevator goods ladder

regulating valve in the closed and very little of a rust or welding slag is enough to destroy grinding was a good sealing surface of the valve seat. Moreover, the dirt will on the valve spool and valve seat caused by wear and tear,

affecting its normal operation.
