一、进口气瓶减压阀概述

进口气瓶减压阀（威盾VTON），Cylinder pressure reducing valve，就是将气体钢瓶中的高压气体减为实验及工况所需的低压气体压力的减压阀。采用活塞式减压结构，输出压力稳定，主要用于石油化工、化纤、照明电器、热处理、冶金、玻璃、食品、医药、电子、国防航天、航空等主导领域的氮气钢瓶，氧气钢瓶，氦气钢瓶，氢气钢瓶，氩气钢瓶，乙炔钢瓶的出口减压。

各种气体一般都是贮存在专用的高压气体钢瓶中，使用时通过减压阀使气体压力降至实验所需范围，再经过其它控制阀门细调，使气体输入使用系统。由于气瓶内压力较高，而气焊和气割和使用点所需的压力却较小，所以需要用减压器来把储存在气瓶内的较高压力的气体降为低压气体，并应保证所需的工作压力自始至终保持稳定状态。进口气瓶减压阀是将高压气体降为低压气体、并保持输出气体的压力和流量稳定不变的调节装置。

A cylinder pressure reducing valve (VTON) is a pressure reducing valve that reduces the high-pressure gas in a gas cylinder to the low-pressure gas pressure required for experiments and operating conditions. Adopting a piston type pressure reducing structure, with stable output pressure, it is mainly used for outlet pressure reduction of nitrogen steel cylinders, oxygen steel cylinders, helium steel cylinders, hydrogen steel cylinders, argon steel cylinders, acetylene steel cylinders in leading fields such as petrochemicals, chemical fibers, lighting appliances, heat treatment, metallurgy, glass, food, medicine, electronics, national defense aerospace, aviation, etc.

Various gases are generally stored in specialized high-pressure gas cylinders. When in use, the gas pressure is reduced to the required range through a pressure reducing valve, and then finely adjusted through other control valves to input the gas into the usage system. Due to the high pressure inside the gas cylinder, while the pressure required for gas welding, cutting, and usage points is relatively low, a pressure reducer is needed to reduce the high pressure gas stored in the cylinder to low pressure gas, and the required working pressure should be maintained in a stable state from beginning to end. The imported gas cylinder pressure reducing valve is a regulating device that reduces high-pressure gas to low-pressure gas and maintains stable pressure and flow rate of the output gas.

三、进口气瓶减压阀安装说明

1、用下扳将减压器进出气接头螺纹与气瓶阀螺纹或高低压侧管路可靠的连接，一防止气体泄漏。请勿转动减压器本体，应夹持本体，转动螺母拧紧。

2、在安装过程中，应确保减压器进、出气接头与减压器连接处不会发生松动，否则将会导致气体泄漏，造成安全重大隐患。

3、彻底清除气瓶和管路系统与减压器连接位置处的油污、水及灰尘，一旦杂质进入气体减压器内，将会导致污染气体，阻塞气体通道或产生其他麻烦。

4、如果管路上的螺纹变形，无法与气体减压器顺利地装上时，就不要强行连接，否则会导致管路系统及气体减压器上的螺纹损坏，从而引起严重事故。

1. Use the lower wrench to reliably connect the threads of the inlet and outlet joints of the pressure reducer to the threads of the gas cylinder valve or the high and low pressure side pipelines to prevent gas leakage. Do not rotate the pressure reducer body. Instead, clamp the body and tighten the nut.

2. During the installation process, it should be ensured that the inlet and outlet joints of the pressure reducer and the connection between the pressure reducer do not become loose, otherwise it will cause gas leakage and pose a major safety hazard.

3. Thoroughly remove oil, water, and dust from the connection between the gas cylinder and pipeline system and the pressure reducer. Once impurities enter the gas pressure reducer, it will cause gas pollution, block gas channels, or cause other troubles.

4. If the threads on the pipeline are deformed and cannot be smoothly installed with the gas pressure reducer, do not force the connection, otherwise it will cause damage to the threads on the pipeline system and gas pressure reducer, leading to serious accidents.
