六、進口水用高壓減壓閥安裝說明：
1、安裝高壓氣體減壓閥之前必須對管路系統進地沖洗清理，以防焊渣、氧化皮等臟物流入閥內，影響閥門正常工作。
2、高壓氣體減壓閥應安裝在便于操作和維修的地方，并且必須直立安裝在水平管路上（見安裝示意圖）應注意使管路中介質的流向與閥體上箭頭所示方向一致，切勿裝反
3、高壓氣體減壓閥在安裝使用時，應先把旁通管路上的截止閥打開，排除管路中的冷凝水和汽水混合物，以防減壓閥開啟時產生水擊現象損壞減壓閥，當無異常現象后，按順時針方向緩慢旋轉調節螺釘，將出口壓力調至所需要的壓力（以閥后表壓為準），調整好后，將鎖緊螺母鎖緊，擰上防護罩。
4、減壓閥前應安裝過濾器，以防止介質中的雜質進入減壓閥，影響其性能。
5、安裝的減壓閥前后應有一段直管，閥前直管長度約為600毫米，閥后直管長度約為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.
