一、进口高压气体减压阀产品概述
进口高压气体减压阀,High pressure gas reducing valve,也叫高压气体调压阀,是一种自动降低管路工作压力的专门装置,活塞式高压气体减压阀是采用控制阀体内的启闭件的开度来调节介质的流量,将介质的压力降低,同时借助阀后压力的作用调节启闭件的开度,使阀后压力保持在一定范围内,适用于各种高压的气体管道,压力最高可以达到16Mpa或者25Mpa。活塞式高压气体减压阀的特点是在进口压力不断变化的情况下,保持出口压力值在一定的范围内。在应用活塞式高压气体减压阀时,必须遵循其适用规范的要求,以确保经营正常进行。高压气体减压阀主要用于气体管路,如空气、氩气、氩气、氩气、液化气、天然气等气体介质。
High pressure gas reducing valve, also known as high-pressure gas regulating valve, is a specialized device that automatically reduces the working pressure of pipelines. The piston type high-pressure gas reducing valve adjusts the flow rate of the medium by controlling the opening and closing parts inside the valve body, reducing the pressure of the medium. At the same time, the opening of the opening and closing parts is adjusted by the pressure behind the valve to maintain the pressure behind the valve within a certain range. It is suitable for various high-pressure gas pipelines, and the pressure can reach up to 16Mpa or 25Mpa. The characteristic of a piston type high-pressure gas pressure reducing valve is to maintain the outlet pressure value within a certain range when the inlet pressure is constantly changing. When applying piston type high-pressure gas pressure reducing valves, it is necessary to follow the requirements of their applicable specifications to ensure normal operation. High pressure gas pressure reducing valves are mainly used in gas pipelines, such as air, argon, argon, liquefied gas, natural gas and other gas media.
