1、升降货梯http://m.iyunsun.com/调压阀支撑措施不到位，如果不加设支撑或者支撑加设不当都可能造成调节阀阀杆与阀座的不同心，造成调压阀发热，容易导致差变或使填料泄漏等故障。即使升降货梯调节阀有固定和支撑措施，也必须定期进行检查，一般2～3个月检查一次。
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、升降货梯安装时紧固不均匀，人为的某些碰撞给调节阀及其管道造成的应力等。这些应力作用在调节阀及其管线上，很容易造成调压阀发热，严重时会影响到升降机上调节系统本身，因此，任何时刻都要保证避免或消除应力，把应力导向远离调节阀的地方。
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、升降货梯http://m.iyunsun.com/调压阀内有杂物，要经常检查调节阀连接升降机的管道内有无铁锈、焊渣、污物等，发现后应及时清除。因为升降货梯调节阀在关闭时，很小的一块铁锈或焊渣就足以破坏研磨得很好的阀座密封面，况且这些污物也会对调节阀阀芯和阀座造成磨损，影响其正常运行。
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.
