、升降貨梯http://www.8kvv.com/調(diào)壓閥支撐措施不到位，如果不加設(shè)支撐或者支撐加設(shè)不當(dāng)都可能造成調(diào)節(jié)閥閥桿與閥座的不同心

，造成調(diào)壓閥發(fā)熱

，容易導(dǎo)致差變或使填料泄漏等故障。即使升降貨梯調(diào)節(jié)閥有固定和支撐措施

，也必須定期進(jìn)行檢查

，一般2～3個(gè)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.

、升降貨梯安裝時(shí)緊固不均勻

，人為的某些碰撞給調(diào)節(jié)閥及其管道造成的應(yīng)力等。這些應(yīng)力作用在調(diào)節(jié)閥及其管線上

，很容易造成調(diào)壓閥發(fā)熱

，嚴(yán)重時(shí)會(huì)影響到升降機(jī)上調(diào)節(jié)系統(tǒng)本身，因此

，任何時(shí)刻都要保證避免或消除應(yīng)力

，把應(yīng)力導(dǎo)向遠(yuǎn)離調(diào)節(jié)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.

、升降貨梯 http://www.8kvv.com/調(diào)壓閥內(nèi)有雜物

，要經(jīng)常檢查調(diào)節(jié)閥連接升降機(jī)的管道內(nèi)有無鐵銹、焊渣

、污物等

，發(fā)現(xiàn)后應(yīng)及時(shí)清除。因?yàn)樯地浱菡{(diào)節(jié)閥在關(guān)閉時(shí)

，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(huì)對(duì)調(diào)節(jié)閥閥芯和閥座造成磨損，影響其正常運(yùn)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.
