目前钻井泥浆固控系统中多采用内置大通径流程管线,一套好的罐阀门设计是其功能完善与否的关键。要保证罐面整洁、防变形防掉落,又要保证操作方便可靠、开关顺畅、指示准确和便于维护的要求,笔者集多年经验,优化设计出一种可斜拉旋升式海底阀,并与常规海底阀进行应用分析,以供业内同行探讨。 At present, the drilling mud solid control system mostly adopts the built-in large-diameter process pipeline, and the design of a good canister valve is the key to its perfect function. To ensure the tank surface neat, anti-deformation anti-drop, but also to ensure easy and reliable operation, smooth switch, indicating accurate and easy maintenance requirements, the author set many years of experience, optimize the design of a tilt-pull rotary submarine valve, and Application analysis with conventional submarine valve for industry peers to explore.
