目前在地质勘探工作中,广泛使用的钻探冲洗泵多为仿苏200/40、200/30、100/30等型号,这些冲洗泵所采用的进、出水阀门,均为弹簧式阀门,在使用中,特别是使用泥浆时,阀门磨损的非常快,时常发生故障,严重影响正常地钻进工作.这种阀门每台水泵有8个,主要是由活阀爪、活阀片、弹簧、活阀压盖等零件组成,不但制作困难,而且成本也较高.因此,有些勘探队就开始采用钢球来代替过去的阀门,即称球形阀,但是仍不够理想,
Currently in the geological exploration work, the widely used drilling flushing pump is mostly imitation Su 200 / 40,200 / 30,100 / 30 and other models, these flushing pump used inlet and outlet valves are spring-type valve, the use of In particular, the use of mud, the valve wear very fast, frequent failures, seriously affecting the normal drilling work.This valve each pump has eight, mainly by the live valve claw, live valve, spring, live Valve gland and other components, not only difficult to make, but also higher costs.Therefore, some exploration teams began to use the ball instead of the past valve, known as the ball valve, but still not ideal,
