气液联动阀的维护与保养

Daily Care and Maintenance of Gas-oil Valve

阐述了气液联动阀的基本结构和工作原理、操作程序、过滤器的清洗与更换、气源管和检测管的检查与吹扫、气液罐液压油及油位的检查、电池电压的检查等日常维护与保养工作要点以及冬季运行应注意的问题。给出了GOV阀在压力正常情况下异常关断、Lineguard通信功能失灵、气源管及检测管接口处漏气、液联动阀关阀不到位、现场与远传信号不同步等一些常见故障排除方法。

This paper describes the key point of gas-oil valve in daily care and maintenance, including the basic structure, operating procedure, cleaning of filter and replacement, inspection of air-tube and test tube, inspection of hydraulic oil of gas-liquid and oil-level,inspection of voltage of battery,also the problems to be focused on in winter operation. The paper lists following common failures of the gas-oil valve,including abnormal 'off' under the condition of normal pressure, failure of Lineguard communication function, air leakage at the junction of air-tube and test tube, unable 'fine off' and out of sync signal between field signal and remote signal and. The trouble-shooting methods are given.
