smc減壓閥的基本作用原理是靠閥內流道對水流的局部阻力降低水壓,水壓降的范圍由連接閥瓣的薄膜或活塞兩側的進出口水壓差自動調節。定比減壓原理是利用閥體中浮動活塞的水壓比控制,進出口端減壓比與進出口側活塞面積比成反比,這種減壓閥工作平穩無振動,使得國內減壓閥生產技術進一步提高;閥體內無彈簧,故無彈簧銹蝕、金屬疲勞失效之慮;密封性能良好不滲漏,因而既減動壓(水流動時)又減靜壓(流量為0時);特別是在減壓的同時不影響水流量。減壓閥通常有DN15~DN100等多種規格,閥前、后的工作壓力分別為<1MPa和0.1~0.5MPa,調壓范圍誤差為±5%~10%。

順時針調節手輪,調壓彈簧被壓縮,推動膜片組件下移,通過閥桿,打開閥芯,則入口氣壓力經閥芯節流降壓,壓力輸出
出口壓力氣體經反饋管進入膜片下腔,在膜片產生一個向上的推力。當此推力與調壓彈簧力平衡時,出口壓力便穩定一定在值。
1)普通型減壓閥,出口壓力不要超過進口壓力的85%;精密減壓閥,出口要壓力不要超過進口壓力的90%。輸出壓力不得超過設定壓力的zui大值。
2)連接配管要充分吹洗。
3)空氣的流動方向按箭頭方向安裝,不得裝反。
4)使用塑料材質的減壓閥,應避免陽光直射
