使用:
減壓閥啟用前,應(yīng)打開旁通閥(沖洗閥),清掃管道
污物,管道沖洗干凈后,關(guān)閉旁通閥和沖洗閥,然后
。固定好調(diào)節(jié)螺釘,蓋好防護(hù)帽。如果減壓閥出現(xiàn)故
障或要修理時應(yīng)先慢慢地打開旁通閥,同時關(guān)閉閥門
啟用減壓閥。有的蒸汽減壓閥前有疏水閥,需要先開
啟,再微開減壓閥后的切斷閥,后把減壓閥前的切
節(jié)螺釘,使閥后壓力達(dá)到預(yù)定值,隨即慢慢地開啟減
壓閥后的切斷閥,校正閥門出口壓力,直到滿意為止
前的切斷閥,手動大致調(diào)節(jié)旁通閥,使減壓閥出口壓
斷閥打開,觀看減壓閥前后的壓力表,調(diào)整減壓閥調(diào)
閥,更換或修理減壓閥。待減壓閥更換或修理好后,
在恢復(fù)正常。
