进口气瓶减压阀
一、进口气瓶减压阀概述
品牌：美国欧可OKE
进口气瓶减压阀，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。

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、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。
四、进口气瓶减压阀操作说明
1、在气体进入减压器之前，须确认已对管路系统（含减压器）按要求进行吹扫或进行抽真空处理。
2、在气体进入减压器之前，须确认减压器调压把手处于旋松状态（逆时针旋松调压把手），否则供气初期的瞬时压力有可能损坏膜片，从而导致减压器失效，严重时会危及人身安全。
3、缓慢打开减压器入口侧的供气阀门，用肥皂水火专用检测仪对减压器各连接处进行检漏。
▲ 注意：打开供气阀门时，人体不得正对或背对减压器。
4、顺时针旋转减压器调压把手，将压力（或流量）调到所需要的刻度指示位置，并用肥皂水或专用检测仪对减压器各连接处进行检漏。
▲ 注意：在减压器供气过程中，如果发现有任何异常的机械振动、噪音、卡住或压力异常升高的现象，表明减压器已存在故障，应立即停止使用。

Imported gas cylinder pressure reducing valve
I. Overview of imported gas cylinder pressure reducing valve
Brand: US Ouke OKE
The Cylinder pressure reducing valve is a pressure reducing valve that reduces the high pressure gas in the gas cylinder to the low pressure gas pressure required for the experimental and working conditions. It adopts piston type decompression structure and stable output pressure. It is mainly used in nitrogen steel cylinders, oxygen cylinders, helium gas in the leading fields of petrochemical, chemical fiber, lighting, heat treatment, metallurgy, glass, food, medicine, electronics, defense aerospace, aviation, etc. Cylinder, hydrogen cylinder, argon cylinder, acetylene cylinder outlet decompression.
All kinds of gases are generally stored in special high-pressure gas cylinders. When used, the gas pressure is reduced to the required range by the pressure reducing valve, and then finely adjusted by other control valves to make the gas input into the system. Since the pressure inside the cylinder is high, and the pressure required for gas welding and gas cutting and use points is small, a pressure reducer is required to reduce the higher pressure gas stored in the cylinder to a low pressure gas, and it should be ensured. The required working pressure is stable from start to finish. The imported cylinder pressure reducing valve is an adjusting device that reduces the high pressure gas to a low pressure gas and keeps the pressure and flow rate of the output gas constant.

Third, the import cylinder pressure reducing valve installation instructions
1. Use the lower wrench to connect the pressure reducer into the gas outlet thread and the gas cylinder valve thread or the high and low pressure side pipeline to prevent gas leakage. Do not turn the pressure reducer body. Hold the body and turn the nut to tighten.
2. During the installation process, it should be ensured that the connection between the inlet and outlet of the pressure reducer and the pressure reducer will not loosen, otherwise it will cause gas leakage and cause serious safety hazards.
3. Thoroughly remove the oil, water and dust from the connection between the cylinder and the piping system and the pressure reducer. Once the impurities enter the gas pressure reducer, it will cause polluting gas, block the gas passage or cause other troubles.
4. If the thread on the pipeline is deformed and cannot be installed smoothly with the gas pressure reducer, do not forcibly connect it. Otherwise, the thread on the piping system and the gas pressure reducer will be damaged, causing serious accidents.
Fourth, the import cylinder pressure reducing valve operation instructions
1. Before the gas enters the pressure reducer, it must be confirmed that the piping system (including the pressure reducer) has been purged or vacuumed as required.
2. Before the gas enters the pressure reducer, make sure that the pressure regulator handle is fully loosened (turn the pressure knob counterclockwise), otherwise the instantaneous pressure at the initial stage of air supply may damage the diaphragm, resulting in decompression. Invalid device, in severe cases, endangers personal safety.
3. Slowly open the air supply valve on the inlet side of the pressure reducer, and use a special tester for soap and water to check the connection of the pressure reducer.
?▲ Note: When opening the air supply valve, the human body must not face or face the pressure reducer.
4. Turn the pressure reducer knob clockwise to adjust the pressure (or flow rate) to the desired scale indication position, and use soapy water or a special detector to check the connections of the pressure reducer.
▲ Note: If any abnormal mechanical vibration, noise, jamming or abnormal increase in pressure is found during the supply of the pressure reducer, it indicates that the pressure reducer has a fault and should be stopped immediately.
