進口高壓氣體減壓閥
一、進口高壓氣體減壓閥 產品概述
品牌：美國歐可OKE
進口高壓氣體減壓閥，High pressure gas reducing valve，也叫高壓氣體調壓閥，是一種自動降低管路工作壓力的專門裝置，活塞式高壓氣體減壓閥是采用控制閥體內的啟閉件的開度來調節介質的流量，將介質的壓力降低，同時借助閥后壓力的作用調節啟閉件的開度，使閥后壓力保持在一定范圍內，適用于各種高壓的氣體管道，壓力可以達到16Mpa或者25Mpa。活塞式高壓氣體減壓閥的特點是在進口壓力不斷變化的情況下，保持出口壓力值在一定的范圍內。在應用活塞式高壓氣體減壓閥時，必須遵循其適用規范的要求，以確保經營正常進行。高壓氣體減壓閥主要用于氣體管路，如空氣、氬氣、氬氣、氬氣、液化氣、天然氣等氣體介質。

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.
