摘　　要：研制的采气井口装置单流阀泄压工具能将井口阀门阀腔或套管头环空内的压力安全泄掉,解决了井口维护作业中阀门阀腔或套管头环空内压力不清楚时的泄压问题,以及单流阀在失效的情况下对其进行更换的问题,为井口维护作业提供了安全保证。The single flow valve is mainly installed on the valve and casing head in the wellhead gas recovery tree, which can relieve the pressure safety in the hole of the valve cavity or casing head in the wellhead, and solve the problems of pressure relief when the pressure of valve cavity or casing head is not clear in the wellhead maintenance operation, and the problem of replacing the single flow valve in the case of failure and maintenance for the wellhead. The operation provides security guarantee.
