进口高压气体减压阀
一、进口高压气体减压阀 产品概述
品牌：美国欧可OKE
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。

Imported high pressure gas pressure reducing valve
I. Imported high pressure gas pressure reducing valve Product overview
Brand: US Ouke OKE
The imported high pressure gas reducing valve, also called high pressure gas pressure regulating valve, is a special device for automatically reducing the working pressure of the pipeline. The piston type high pressure gas pressure reducing valve adopts the opening and closing member in the control valve body. The opening degree is used to adjust the flow rate of the medium, and the pressure of the medium is lowered. At the same time, the opening degree of the opening and closing member is adjusted by the action of the post-valve pressure, so that the post-valve pressure is maintained within a certain range, and is suitable for various high-pressure gas pipelines, pressure Up to 16Mpa or 25Mpa. The piston type high pressure gas pressure reducing valve is characterized by keeping the outlet pressure value within a certain range under the condition that the inlet pressure is constantly changing. When applying a piston high pressure gas pressure reducing valve, it must comply with the requirements of its applicable specifications to ensure normal operation. The high pressure gas pressure reducing valve is mainly used for gas pipelines such as air, argon, argon, argon, liquefied gas, natural gas and the like.
