1、重庆升降机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。
Zhejiang Lifts regulator support measures in place if we do not set up or support plus support provided may result in improper valve stem and seat of different heart, causing fever regulator, easily lead to poor change or make packing leakage and other faults. Even if the valve has a fixed and support measures must also be checked regularly, usually 2 to 3 months, check again.

2、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，严重时会影响到浙江货梯上调节系统本身，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。
Zhejiang freight elevator installation when tightening is not even certain collision artificial valve and piping to adjust the stress caused by, these stress in regulating valve and pipeline regulator is likely to cause fever, severe affect Zhejiang adjust the freight system itself, so any time we must ensure to avoid or eliminate stress, the stress away from the valve guide areas.

3、调压阀内有杂物，要经常检查调节阀连接浙江货梯的管道内有无铁锈、焊渣、污物等，发现后应及时清除。因为调节阀在关闭时，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。
There is debris in the Zhejiang freight regulator should always check valve connected in the pipeline freight Zhejiang whether the rust, welding slag, dirt, etc., should be promptly removed after the discovery. Because the control valve is closed, a small piece of rust or welding slag abrasive enough to destroy a very good seat sealing surface, besides these contaminants will also cause spool valve and seat wear, affecting its normal operation.
