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的啟閉件的開度來調節介質的流量，將介質的壓力降低，同時借助閥后壓力的作用調節啟閉件的開度，使閥后壓力保持在一定范圍內，并在閥體內或閥后噴入冷卻水，將介質的溫度降低，這種閥門稱為減壓減溫閥。減壓閥快易優自動化選型有收錄。該閥的特點，是在進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。

德國力士樂減壓閥是在管道輸送中*的閥門產品。使用減壓閥應按照說明書操作，否則會因使用操作不當達不到減壓的效果。

1．減壓閥啟用前，應打開旁通閥（沖洗閥），清掃管道污物，管道沖洗干凈后，關閉旁通閥和沖洗閥，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，調整減壓閥調節螺釘，使閥后壓力達到預定值，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。固定好調節螺釘，蓋好防護帽。

3．如果減壓閥出現故障或要修理時應先慢慢地打開旁通閥，同時關閉閥門前的切斷閥，手動大致調節旁通閥，使減壓閥出口壓力基本上穩定在預訂值上下，再關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，在恢復正常。
