【進(jìn)口水用減壓閥】詳細(xì)說明：
水用減壓閥：法蘭連接形式、彈簧薄膜式結(jié)構(gòu)、密封面材料為橡膠銅合金、公稱壓力 PN10~PN16、閥體材料為灰鑄鐵或球墨鑄鐵的減壓閥。該產(chǎn)品針對(duì)高層、超高層建筑設(shè)計(jì)，是解決高層建筑生活用水、消防用水系統(tǒng)中，要求流量大、靈敏度高等場(chǎng)合的理想產(chǎn)品。其性能更加*，*取代中間水箱，節(jié)約建筑中間水箱的費(fèi)用，擴(kuò)大建筑物的使用面積。水減壓閥,水用減壓閥在城市建筑,高層建筑的冷熱供水系統(tǒng)中,可取代常規(guī)分區(qū)水管,節(jié)省設(shè)備。也可在通常的冷熱水管網(wǎng)中,起減壓穩(wěn)壓作用。,自來水減壓閥本系列減壓閥屬于先導(dǎo)活塞式減壓閥.由主閥和導(dǎo)閥兩部分組成.主閥主要由閥座、主閥盤、活塞、彈簧等零件組成。導(dǎo)閥主要由閥座、閥瓣、膜片、彈簧、調(diào)節(jié)彈簧等零件組成。通過調(diào)節(jié)調(diào)節(jié)彈簧壓力設(shè)定出口壓力、利用膜片傳感出口壓力變化，通過導(dǎo)閥啟閉驅(qū)動(dòng)活塞調(diào)節(jié)主閥節(jié)流部位過流面積的大小，實(shí)現(xiàn)減壓穩(wěn)壓功能。
Water pressure relief valve: flange connection type, spring film structure, sealing surface material for rubber copper alloy, nominal pressure PN10 ~ PN16, valve body material for gray iron or ductile iron pressure relief valve. This product is aimed at the design of high-rise and super-high-rise buildings. It is an ideal product to solve the high-rise buildings'domestic water and fire water systems, which require large flow and high sensitivity. Its performance is more superior, completely replacing the intermediate water tank, saving the cost of building the intermediate water tank, expanding the use area of the building. Water pressure relief valves, water pressure relief valves in urban buildings, high-rise buildings in the cold and hot water supply system, can replace conventional zoning water pipes, save equipment. It can also play the role of decompression and stabilization in the normal cold and hot water pipeline network. Tap water pressure relief valves This series of pressure relief valves belong to pilot piston type pressure relief valves. They are composed of main valve and pilot valve. The main valve is mainly composed of seat, main valve disc, piston, spring and other parts. The guide valve is mainly composed of seat, disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting the spring pressure, the diaphragm is used to sense the outlet pressure change, and the pilot valve opens and closes to drive the piston to adjust the flow area of the throttle part of the main valve, so as to realize the function of reducing pressure and stabilizing pressure.
【進(jìn)口水用減壓閥】特性：
1.減壓閥的進(jìn)口壓力波動(dòng)應(yīng)控制在進(jìn)口壓力給定值的80-105，如超過該范圍水管減壓閥的性能會(huì)受影響。
2.通常水用減壓閥的閥后壓力Pc 應(yīng)小于閥前壓力的0.5 倍即Pc<0.5P1。彈簧活塞式減壓閥的每一檔彈簧只在一定的出口壓力范圍內(nèi)適用超出范圍應(yīng)更換彈簧。
3.在介質(zhì)工作溫度比較高的場(chǎng)合般選用先導(dǎo)式活塞式減壓閥或先導(dǎo)式波紋管減壓閥。
4.介質(zhì)為空氣或水液體的場(chǎng)合一般宜選用直接作用薄膜式水減壓閥或先導(dǎo)式薄膜式減壓閥。
5.介質(zhì)為蒸汽的場(chǎng)合宜選用先導(dǎo)活塞式減壓閥或波紋管式減壓閥。
6.為了操作、調(diào)整和維修的方便減壓閥一般應(yīng)安裝在水平管道上。
【進(jìn)口水用減壓閥】結(jié)構(gòu)特點(diǎn)和用處：
減壓閥屬于直接作用式薄膜彈簧減壓閥。主要由調(diào)節(jié)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(qū)動(dòng)閥瓣，控制閥瓣開度完成減壓穩(wěn)壓功能。
水用減壓閥在城市建筑、高層建筑的冷熱供水系統(tǒng)中，可取代常規(guī)分區(qū)水管，節(jié)省設(shè)備。也可在通常的冷熱水管網(wǎng)中，起減壓穩(wěn)壓作用。
本產(chǎn)品調(diào)壓、穩(wěn)壓動(dòng)作平穩(wěn)，適用于水和非腐蝕性液體介質(zhì)的管路。
