进口氦气钢瓶减压阀

四、进口氦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 ts 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 ts 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.

四、进口氦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完全旋松状态（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。

1. Before the gas enters the pressure reducer, it must be confirmed that the pipeline system (including the pressure reducer) has been purged or vacuumed as required.

2. Before gas enters the pressure reducer, it is necessary to confirm that the pressure regulating handle of the pressure reducer is fully loosened (counterclockwise loosening of the pressure regulating handle). Otherwise, the instantaneous pressure in the early stage of gas supply may damage the diaphragm, leading to the failure of the pressure reducer, and in severe cases, it may endanger personal safety.

3. Slowly open the gas supply valve on the inlet side of the pressure reducer and use a soap water fire special detector to detect leaks at all connections of the pressure reducer.

▲ Attention: When opening the gas supply valve, the human body should not be facing or facing away from the pressure reducer.

4. Rotate the pressure regulator handle clockwise to adjust the pressure (or flow) to the desired scale indication position, and use soapy water or a specialized detector to check for leaks at each connection of the pressure regulator.

▲ Attention: If any abnormal mechanical vibration, noise, jamming, or abnormal pressure increase are found during the gas supply process of the pressure reducer, it indicates that there is a malfunction in the pressure reducer and should be stopped immediately.
