進(jìn)口黃銅減壓閥產(chǎn)品概述：

德國《DE LOCKE》洛克進(jìn)口黃銅減壓閥是通體內(nèi)的啟閉件的開度來調(diào)節(jié)介質(zhì)的流量，將介質(zhì)的壓力降低，同時(shí)借助閥后壓力的作用調(diào)節(jié)啟閉件的開度，使閥后壓力保持在使用工況所需的壓力范圍。從流體力學(xué)的觀點(diǎn)看，減壓閥是一個(gè)局部阻力可以變化的節(jié)流元件，即通過改變節(jié)流面積，使流速及流體的動(dòng)能改變，造成不同的壓力損失，從而達(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié)，使閥后壓力的波動(dòng)與彈簧力相平衡，使閥后壓力在一定的誤差范圍內(nèi)保持恒定。

進(jìn)口黃銅減壓閥產(chǎn)品特點(diǎn)：

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(rèn)為出口壓力不受進(jìn)口壓力的影響（出口壓力的變化量是△P1的8%）。

*的水力特性，壓力損失小，減壓比可達(dá)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)。

Features of imported brass pressure reducing valve:
Using direct acting diaphragm structure, the internal structure is very simple, no jam, reliable performance, durable.
It is dirt resistant and water-proof. It doesn't need filter and bypass pipe. The piping is extremely simple and can save a lot of space and piping cost.
The outlet pressure is precisely adjustable. In general, it can be considered that the outlet pressure is not affected by the inlet pressure (the variation of outlet pressure is 8% of △ P1).
Excellent hydraulic characteristics, small pressure loss, decompression ratio can reach more than 10:1.
It can meet various decompression requirements, especially suitable for branch decompression system.
 

進(jìn)口黃銅減壓閥產(chǎn)品原理：

出口壓力作用在隔膜底面和閥瓣底面，當(dāng)它超過彈簧設(shè)定值時(shí)，壓縮彈簧，使閥瓣關(guān)閉。只要下游無水流動(dòng)，出口壓力將基本保持在設(shè)定值（其變化量僅為入口壓力變化量的8%）；當(dāng)下游用水時(shí)，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(yīng)，使啟閉動(dòng)作趨于平穩(wěn)。

Principle of imported brass pressure reducing valve:
The outlet pressure acts on the bottom of the diaphragm and the bottom of the disc. When it exceeds the spring setting value, it compresses the spring to close the disc. As long as there is no water flow in the downstream, the outlet pressure will be basically kept at the set value (its variation is only 8% of the inlet pressure variation); when water is used in the downstream, the outlet pressure will drop, and the spring will open the diaphragm and open the pressure reducing valve. After a period of continuous flow, the opening of the pressure reducing valve produces self damping effect, which makes the opening and closing action tend to be stable.
