 彈簧薄膜式減壓閥Y42X原理 彈簧薄膜式減壓閥Y42X主要由調(diào)節(jié)彈簧、膜片、活塞、閥座、閥瓣等零件組成。減壓閥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(wěn)壓功能。該直接作用彈簧薄膜式減壓閥在城市建筑、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)省設備。也可在通常的冷熱水管網(wǎng)中,起減壓穩(wěn)壓作用。該直接作用彈簧薄膜式減壓閥調(diào)壓、穩(wěn)壓動作平穩(wěn)，適用于水和非腐蝕性液體介質(zhì)的管路。 彈簧薄膜式減壓閥Y42X指標

Spring diaphragm reducing valve Y42X principle
Spring diaphragm reducing valve Y42X is mainly composed of a regulating spring, diaphragm, piston, valve seat, valve and other parts. Pressure reducing valve with diaphragm direct sensing downstream pressure actuated valve, control valve opening degree complete decompression function. The direct effect of spring diaphragm reducing valve in city construction, high-rise building hot and cold water supply system, can replace the conventional partition pipe, saving equipment. Also available in the usual hot and cold water pipe network, pressure reducing and stabilizing role play. The direct effect of spring diaphragm reducing valve voltage regulator, steady movement, applicable to water and non corrosive liquid medium pipeline.
