進口水用減壓閥
一、進口水用減壓閥 產品概述
品牌：美國歐可OKE
進口水用減壓閥，Water pressure reducing valve，也叫水用調壓閥，主要由調節彈簧、膜片、活塞、閥座、閥瓣等零件組成，利用膜片直接傳感下游壓力驅動閥瓣，控制閥瓣開度完成減壓穩壓功能的閥門。
美國歐可OKE進口水用減壓閥主要應用在城市建筑、高層建筑的冷熱供水系統中，可取代常規分區水管，節省設備。也可在通常的冷熱水管網中，起減壓穩壓作用。

六、進口水用減壓閥 安裝注意事項
1.為了操作和維護方便，該閥一般直立安裝在水平管道上。
2.減壓閥安裝必須嚴格按照閥體上的箭頭方向保持和流體流動方 減壓閥
向一致。如果水質不清潔含有一些雜質，必須在減壓閥的上游進水口安裝過濾器
3.為了防止閥后壓力超壓，應在離閥出口不少于4M處安裝一個減壓閥。
4.減壓閥在管道中起到一定的止回作用，為了防止水錘的危害，也可安裝小的膨脹水箱，防止損壞管道和閥門，過濾器必須安裝在減壓閥的進水管前，而膨脹水箱必須安裝在減壓閥出水管后！

Imported water pressure reducing valve
I. Imported water pressure reducing valve Product overview
Brand: US Ouke OKE
Imported water pressure reducing valve, also known as water pressure regulating valve, is mainly composed of adjusting spring, diaphragm, piston, valve seat, valve disc and other parts, using diaphragm to directly sense downstream pressure-driven valve flap The valve that controls the valve opening to complete the decompression and pressure regulation function.
The US Ou Kee OKE water 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. Imported water pressure reducing valve 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!
