力士乐减压阀操作使用说明

力士乐减压阀是采用控制阀体内的启闭件的开度来调节介质的流量，将介质的压力降低，同时借助阀后压力的作用调节启闭件的开度，使阀后压力保持在一定范围内，并在阀体内或阀后喷入冷却水，将介质的温度降低，这种阀门称为减压减温阀。减压阀快易优自动化选型有收录。该阀的特点，是在进口压力不断变化的情况下，保持出口压力和温度值在一定的范围内。

德国力士乐减压阀是在管道输送中*的阀门产品。使用减压阀应按照说明书操作，否则会因使用操作不当达不到减压的效果。

1．减压阀启用前，应打开旁通阀（冲洗阀），清扫管道污物，管道冲洗干净后，关闭旁通阀和冲洗阀，然后启用减压阀。

2．有的蒸汽减压阀前有疏水阀，需要先开启，再微开减压阀后的切断阀，zui后把减压阀前的切断阀打开，观看减压阀前后的压力表，调整减压阀调节螺钉，使阀后压力达到预定值，随即慢慢地开启减压阀后的切断阀，校正阀门出口压力，直到满意为止。固定好调节螺钉，盖好防护帽。

3．如果减压阀出现故障或要修理时应先慢慢地打开旁通阀，同时关闭阀门前的切断阀，手动大致调节旁通阀，使减压阀出口压力基本上稳定在预订值上下，再关闭减压阀后的切断阀，更换或修理减压阀。待减压阀更换或修理好后，在恢复正常。
