进口高压减压阀的选用： 

进口高压气体减压阀的根据使用要求选定减压阀的类型和调压精度，再根据所需zui大输出流量选择其通径。决定阀的气源压力时，应使其大于zui输出压力0．1MPa。减压阀一般安装在分水滤气器之后，油雾器或定值器之前，并注意不要将其进、出口接反；阀不用时应把旋钮放松，以免膜片经常受压变形而影响其性能。

进口高压减压阀产品安装说明：

1、安装高压减压阀之前必须对管路系统进地冲洗清理，以防焊渣、氧化皮等脏物流入阀内，影响阀门正常工作。

2、高压气体减压阀应安装在便于操作和维修的地方，并且必须直立安装在水平管路上(见安装示意图)应注意使管路中介质的流向与阀体上箭头所示方向一致，切勿装反.

3、高压气体减压阀在安装使用时，应先把旁通管路上的截止阀打开，排除管路中的冷凝水和汽水混合物，以防减压阀开启时产生水击现象损坏减压阀，当无异常现象后，按顺时针方向缓慢旋转调节螺钉，将出口压力调至所需要的压力(以阀后表压为准)，调整好后，将锁紧螺母锁紧，拧上防护罩。

4、减压阀前应安装过滤器，以防止介质中的杂质进入减压阀，影响其性能。

5、安装的减压阀前后应有一段直管，阀前直管长度约为600毫米，阀后直管长度约为1000毫米。

1. Before installing the high-pressure pressure reducing valve, the pipeline system must be flushed and cleaned to prevent welding slag, oxide scale and other dirt from flowing into the valve and affecting the normal operation of the valve.

2. The high-pressure gas pressure reducing valve should be installed in a place convenient for operation and maintenance, and it must be installed vertically on the horizontal pipeline (see the installation diagram). Attention should be paid to make the flow direction of medium in the pipeline consistent with the direction indicated by the arrow on the valve body, and do not install it reversely

3. When the high pressure gas pressure reducing valve is installed and used, the stop valve on the bypass pipeline should be opened first to remove the condensate water and steam water mixture in the pipeline, so as to prevent water hammer from damaging the pressure reducing valve when the pressure reducing valve is opened. When there is no abnormal phenomenon, slowly rotate the adjusting screw clockwise to adjust the outlet pressure to the required pressure (based on the gauge pressure behind the valve). After the adjustment, the outlet pressure should be adjusted, Lock the lock nut and screw on the protective cover.

4. A filter should be installed before the pressure reducing valve to prevent impurities in the medium from entering the pressure reducing valve and affecting its performance.

5. There should be a straight pipe before and after the pressure reducing valve. The length of the straight pipe in front of the valve is about 600mm, and the length of the straight pipe behind the valve is about 1000mm.
