六、进口水用可调式减压阀 安装注意事项
1.为了操作和维护方便，该阀一般直立安装在水平管道上。
2.减压阀安装必须严格按照阀体上的箭头方向保持和流体流动方 减压阀
向一致。如果水质不清洁含有一些杂质，必须在减压阀的上游进水口安装过滤器
3.为了防止阀后压力超压，应在离阀出口不少于4M处安装一个减压阀。
4.减压阀在管道中起到一定的止回作用，为了防止水锤的危害，也可安装小的膨胀水箱，防止损坏管道和阀门，过滤器必须安装在减压阀的进水管前，而膨胀水箱必须安装在减压阀出水管后！

Adjustable pressure reducing valve for imported water
1. Adjustable pressure reducing valve for imported water Product Overview
Brand: US Ouke OKE
Water adjustable pressure reducing valve is also called water 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 drive. The valve flap controls the valve opening to complete the decompression and pressure regulation function. The pressure reducing valve is equipped with a pressure adjustment button, which can perform various high-precision pressure adjustment control on the pressure reducing valve according to the user's post-valve pressure demand value.
The US Ou Ke OKE imported water adjustable pressure reducing valve is mainly used in the urban and high-rise building's hot and cold water supply system, which can replace the conventional partition water pipe 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, and the hydraulic principle control theory is rationally applied.
◆Stable and reliable work, large traffic
◆Valve opening and closing slowly, no hammer impact (closed time adjustable)
◆High voltage regulation and high adjustment range
◆Good sealing performance and long service life
◆ Easy installation, pressure regulation and maintenance

6. Adjustable pressure reducing valve for imported water Installation precautions
1. For ease of operation and maintenance, the valve is generally mounted upright on a horizontal pipe.
2. The pressure reducing valve must be installed in strict accordance with the direction of the arrow on the valve body and the fluid flow side pressure reducing valve
Consistent. If the water quality is not clean and contains some impurities, the filter must be installed at the upstream inlet of the pressure reducing valve.
3. In order to prevent post-valve pressure overpressure, a pressure reducing valve should be installed at not less than 4M from the valve outlet.
4. The pressure reducing valve plays a certain role in the pipeline. In order to prevent the damage of the water hammer, a small expansion tank can also be installed to prevent damage to the pipeline and the valve. The filter must be installed in front of the inlet pipe of the pressure reducing valve. The expansion tank must be installed after the pressure relief valve outlet!
