浅谈一种多级降压高压差结构在放空阀中的应用设计

Application Design of a Multi Stage Buck High Pressure Differential Structure in Vent Valve

放空控制阀属于控制阀大类中现场工况比较复杂的阀门类型。放空应用阀门是将有压力的气体或者液体,在非工作情况或者紧急状态下,能立即排掉,避免发生其它意外。本文介绍一种多级降压高压差结构在放空环境下的应用,通过多级降压结构设计,以及特殊的先导阀芯结构设计,密封等级高,达到严密关闭切断流体、降噪、降压的效果。

Abstact ： Vent control valve belongs to the complex valve type in the large class of control valve. Venting application valves are pressure gas or liquid, in the non-operating or emergency, can be discharged immediately to avoid other accidents. This paper introduces the application of a multistage depressed pressure difference structure in venting environment, through multistage depressed structure design, and special guide valve structure design to achieve the effect of high seal level, noise reduction and lower pressure.
