六、进口水用高压减压阀安装说明：
1、安装高压气体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。

High pressure relief valve for imported water
1. High pressure relief valve for imported water Product Overview
Brand: US Ouke OKE
Water high-pressure reducing valve is also called high-pressure pressure regulating valve. It is mainly composed of adjusting spring, diaphragm, piston, valve seat and valve disc. It uses diaphragm to directly sense downstream pressure-driven valve. The valve that controls the valve opening to complete the decompression and pressure regulation function. The maximum valve front pressure is 32Mpa, and the outlet is reduced to 0.1Mpa. It is suitable for high-pressure or high-pressure water flow media applications, reducing the high pressure of the inlet to the required pressure value.
The US Ou Ke OKE imported water high pressure relief valve is mainly used in coal mine high pressure, urban high-rise buildings, hotels and other hot and cold water supply systems, which can replace the conventional partition water pipes and save equipment. It can also be used in the normal hot and cold water pipe network to reduce the pressure.
Main features:
◆The structure is novel and reasonable, high pressure and pressure reduction
◆Stable and reliable work, large traffic
◆The valve flap opens and closes slowly, and the high pressure difference is no impact on the hammer (the closing time is adjustable)
◆High voltage regulation and high adjustment range
◆Good sealing performance and long service life

6. Installation instructions for imported high pressure relief valve for water:
1. Before installing the high-pressure gas pressure reducing valve, the pipeline system must be flushed and cleaned to prevent the dirt, such as welding slag and oxide scale, from flowing into the valve, which affects 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 must be installed upright on the horizontal pipeline (see installation diagram). Note that the flow direction of the medium in the pipeline is consistent with the direction indicated by the arrow on the valve body. Do not pretend
3. When installing and using the high-pressure gas pressure reducing valve, first open the shut-off valve on the bypass line to eliminate the condensed water and steam-water mixture in the pipeline to prevent water hammer from being damaged when the pressure-reducing valve is opened. When there is no abnormality, slowly rotate the adjusting screw clockwise to adjust the outlet pressure to the required pressure (according to the valve back pressure). After adjusting, lock the lock nut and screw 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 installed pressure reducing valve. The length of the straight pipe before the valve is about 600 mm, and the length of the straight pipe behind the valve is about 1000 mm.
