液体管道多功能减压阀

Multi-functional pressure regulation valve for liquid pipeline

陡坡液体管道有超压和泄漏两个特殊问题。通过对国内外现行处理技术的分析 ,研制了自力式多功能减压阀。该阀不依赖外部能源工作 ,具有自动节流减压、泄漏超流自动截断、禁开、温升膨胀自动卸压和压力自动开启等多项功能。

The overpressure and leak are two problems in critical downhill section of liquid pipeline.This paper summarizes and analyzes the actual treatment technology at home and abroad,and emphatically introduces a self operated multi functional pressure regulation valve developed by the authors.The pressure regulation valve,working without exterior energy,has the functions of pressure regulating,overflow closing,liquid temperature expansion relieving,and set pressure opening.
