水減壓閥在環保水處理應用Y42X不銹鋼法蘭減壓閥概述：
Y42X不銹鋼法蘭減壓閥屬于直接作用式彈簧薄膜式減壓閥。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。
Y42X法蘭不銹鋼減壓閥在城市建筑、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。

所先認識下水用減壓閥有哪些結構類型，根據減壓原理和結構型式的不同，水用減壓閥可分為比例式減壓閥和可調式減壓閥。
比例式減壓閥：是依據其閥腔內減壓活塞進出口兩端感應面積的差異，實現進、出口壓力成一定比例關系的減壓閥，依據進口壓力設定出口壓力。
可調式減壓閥：是根據水力差動控制原理或水力先導控制（由減壓先導閥控制主閥）原理，以出口壓力的設定值為準，自動調節閥瓣的開啟度和流量，實現出口壓力的減壓和穩定，并與進口壓力的關聯度較小，可通過彈簧調節裝置，對減壓閥出口壓力進行有效調整。
一、薄膜式水用減壓閥工作原理
屬于直接作用彈簧薄膜式的有Y416X、200P、YZ11X型水用減壓閥，在吸取了國外同類產品優點的基礎上適當加大了膜片面積，提高了靈敏度。主要由膜片、磴形閥瓣、調節彈簧等零件組成。利用膜片傳感下游壓力變化驅動閥瓣，改變和控制閥門開度實現減壓穩壓功能。由調定調節彈簧壓力設定出口壓力值。當閥后壓力超過彈簧設定值時，壓縮彈簧，使閥瓣慢慢開度慢慢減小。適用于高層建筑公寓樓和住宅區的支線管路以及公寓、住宅的入戶自來水管減壓使用。
二、活塞式水用減壓閥工作原理
屬于直接作用彈簧活塞式的有Y42X/F型水用減壓閥，當壓力變化時，流入活塞下腔并與活塞上方保持平衡，迫使活塞向移動，改變節流面積，造成壓力損失，實現減壓。由于本閥采用卸荷機構，減小了進口壓力變化對出口壓力的影響，同時加大了出口壓力作用面積，即加大敏感元件作用面積，從而減小了閥門出口壓力偏差，大大提高了減壓閥的穩壓精度。以滿足控制要求。
三、先導式水用減壓閥工作原理
屬于先導膜片式的有200X、ZZYP型水用減壓閥，水流通過導管進入主閥的控制室、并建立向下的壓力，出口壓力也通過導管作用在導閥的膈膜下并與導閥的調節彈簧相對抗。當下游壓力超過導閥彈簧設定值時，導閥關閉，控制室內的水排泄量為0，上閥腔可變壓力達到大，則主閥盤緊閥座減壓閥出口減小。
