产品介绍

一、进口带压力表气体减压阀产品概述

进口带压力表气体减压阀（With pressure gauge Gas pressure reducing valve）是指阀门自带有两个压力表，一个进口压力表，一个出口压力表，可以直接显示进出口压力，对气体直观的压力调节变化，用于气体系统管道，比如空气、氮气、氧气、氢气、氦气、氩气、液化气、天然气等气体，通过调节弹簧压力设定出口压力、利用膜片传感出口压力变化，通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小，实现减压稳压功能，减压阀上带有压力调节手柄，可以方便准确的对减压阀的出口压力进行设定和调节。从流体力学的观点看，减压阀是一个局部阻力可以变化的节流元件，即通过改变节流面积，使流速及流体的动能改变，造成不同的压力损失，从而达到减压的目的。然后依靠控制与调节系统的调节，使阀后压力的波动与弹簧力相平衡，使阀后压力在一定的误差范围内保持恒定。

A gas pressure reducing valve with a pressure gauge refers to a valve that comes with two pressure gauges, one inlet pressure gauge and one outlet pressure gauge, which can directly display the inlet and outlet pressure, and can intuitively adjust the pressure change of gas. It is used in gas system pipelines, such as air, nitrogen, oxygen, hydrogen, helium, argon, liquefied gas, natural gas, etc. The outlet pressure is set by adjusting the spring pressure, and the outlet pressure change is sensed by a diaphragm. The pilot valve opens and closes to drive the piston to adjust the size of the flow surface area at the main valve throttle, achieving pressure reduction and stabilization function. The pressure reducing valve is equipped with a pressure adjustment handle, which can conveniently and accurately adjust the outlet pressure of the pressure reducing valve. Set and adjust the pressure. From the perspective of fluid mechanics, a pressure reducing valve is a throttling element that can change local resistance. By changing the throttling area, the flow rate and kinetic energy of the fluid are changed, resulting in different pressure losses and achieving the purpose of pressure reduction. Then, relying on the adjustment of the control and adjustment system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve remains constant within a certain error range.

二、进口带压力表气体减压阀产品特征

1、广泛用于气体管路，如空气、氮气、氧气、氢气、液化气、天然气等气体。

2、属于先导活塞式减压阀。由主阀和导阀两部分组成。主阀主要由阀座、主阀盘、活塞、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。控制精确。

3、通过调节调节弹簧压力设定出口压力、利用膜片传感出口压力变化，通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小，实现减压稳压功能。进口压力不断变化的情况下，保持出口听压力和温度值在一定的范围内。

1. Widely used in gas pipelines, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas, and other gases.

2. Belongs to a pilot piston type pressure reducing valve. It consists of two parts: the main valve and the pilot valve. The main valve is composed of parts such as valve seat, main valve disc, piston, spring, etc. The pilot valve is mainly composed of parts such as valve seat, valve disc, diaphragm, spring, and regulating spring. Accurate control.

3. By adjusting the spring pressure to set the outlet pressure, using the diaphragm to sense the change in outlet pressure, and driving the piston to adjust the size of the flow area at the throttle position of the main valve through the opening and closing of the pilot valve, the pressure reducing and stabilizing function is achieved. Maintain the outlet listening pressure and temperature values within a certain range while the import pressure is constantly changing.
