力士樂減壓閥操作使用說明

力士樂減壓閥是采用控制閥體內(nèi)的啟閉件的開度來調(diào)節(jié)介質(zhì)的流量，將介質(zhì)的壓力降低，同時(shí)借助閥后壓力的作用調(diào)節(jié)啟閉件的開度，使閥后壓力保持在一定范圍內(nèi)，并在閥體內(nèi)或閥后噴入冷卻水，將介質(zhì)的溫度降低，這種閥門稱為減壓減溫閥。減壓閥快易優(yōu)自動(dòng)化選型有收錄。該閥的特點(diǎn)，是在進(jìn)口壓力不斷變化的情況下，保持出口壓力和溫度值在一定的范圍內(nèi)。

德國力士樂減壓閥是在管道輸送中*的閥門產(chǎn)品。使用減壓閥應(yīng)按照說明書操作，否則會(huì)因使用操作不當(dāng)達(dá)不到減壓的效果。

1．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，然后啟用減壓閥。

2．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，zui后把減壓閥前的切斷閥打開，觀看減壓閥前后的壓力表，調(diào)整減壓閥調(diào)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。固定好調(diào)節(jié)螺釘，蓋好防護(hù)帽。

3．如果減壓閥出現(xiàn)故障或要修理時(shí)應(yīng)先慢慢地打開旁通閥，同時(shí)關(guān)閉閥門前的切斷閥，手動(dòng)大致調(diào)節(jié)旁通閥，使減壓閥出口壓力基本上穩(wěn)定在預(yù)訂值上下，再關(guān)閉減壓閥后的切斷閥，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。
