二、進口不銹鋼水用減壓閥產(chǎn)品特征
1、不銹鋼材質(zhì)，耐磨，耐腐蝕，耐生銹
2、螺紋連接，連接方便，省材料，性價比高
3、極佳的水力特性，壓力損失小
4、加壓比例大，減壓比可達成10：1以上
三、進口不銹鋼水用減壓閥工作原理
出口壓力作用在隔膜底面和閥瓣底面，當它超過彈簧設定值時，壓縮彈簧，使閥瓣關閉。只要下游無水流動，出口壓力將基本保持在設定值（其變化量僅為入口壓力變化量的8%）；當下游用水時，出口壓力下降，彈簧推開隔膜，打開減壓閥。水流連續(xù)流通一陣后，減壓閥的開啟產(chǎn)生自阻尼效應，使啟閉動作趨于平穩(wěn)。
采用直接作用隔膜式結(jié)構(gòu)，內(nèi)部結(jié)構(gòu)非常簡單，無卡阻，性能可靠，經(jīng)久耐用。耐臟防水垢,不需過濾器,不需旁通管,配管極其簡單,能節(jié)省大量空間和配管成本。 出口壓力精密可調(diào)，在一般場合下，可以認為出口壓力不受進口壓力的影響（出口壓力的變化量是△P1的8%）。 極佳的水力特性，壓力損失小，減壓比可達成10：1以上。 可滿足多種減壓要求，特別適用于支管減壓系統(tǒng)。

Imported stainless steel water pressure reducing valve
I. Overview of imported stainless steel water pressure reducing valve
Brand: US Ouke OKE
Imported stainless steel water pressure reducing valve means that the valve body is made of stainless steel 304 or 316. It has the functions of acid and alkali resistance, corrosion resistance and rust resistance. It has good strength, strong toughness and high precision. The decompression regulator valve.
Imported stainless steel water pressure reducing valves are mainly used in various building water supply systems, fire protection systems, central air conditioning systems, heating systems, etc. It is used for branch pipe decompression, which can make the water supply pressure distribution more balanced, avoid partial water supply overpressure, and optimize the high-rise building water supply zone. The imported stainless steel water pressure reducing valve can replace the zone frequency variable frequency water pump. It can replace the district water pump in the fire water supply system and can be used in the household water supply system to protect all the faucets and other water appliances.
Second, the imported stainless steel water pressure reducing valve product features
1, stainless steel, wear-resistant, corrosion-resistant, rust-resistant
2, threaded connection, convenient connection, material saving, cost-effective
3, excellent hydraulic characteristics, low pressure loss
4, the pressure ratio is large, the pressure reduction ratio can reach 10:1 or more
Third, the working principle of imported stainless steel water pressure reducing valve
The outlet pressure acts on the bottom surface of the diaphragm and the underside of the valve flap. When it exceeds the spring setting, the spring is compressed to close the flap. As long as there is no downstream flow, the outlet pressure will remain at the set value (the amount of change is only 8% of the inlet pressure change); when the downstream water is used, the outlet pressure drops, the spring pushes open the diaphragm, and opens the pressure reducing valve. After the water flow is continuously circulated for a while, the opening of the pressure reducing valve produces a self-damping effect, which makes the opening and closing action tend to be stable.
With a direct acting diaphragm structure, the internal structure is very simple, no jamming, reliable performance and durability. It is resistant to dirt and scale, does not require a filter, does not require a bypass pipe, and the piping is extremely simple, saving a lot of space and piping costs. The outlet pressure is precisely adjustable. Under normal circumstances, the outlet pressure can be considered to be unaffected by the inlet pressure (the change in outlet pressure is 8% of ΔP1). Excellent hydraulic characteristics, low pressure loss, and a pressure reduction ratio of 10:1 or more. It can meet a variety of decompression requirements, especially for branch pipe decompression systems.
