電動閥堵塞了怎么處理

人氣:0發表時間:2019/12/10 0:01:52

一般來說,當電動閥遇到這種卡住和堵塞時,我們可以選擇以下兩種方法來解決。

1)清潔

管道內的焊渣、鐵銹、殘渣堵塞或粘在下蓋板、導向位置和平衡孔中,造成閥芯表面、導向表面劃傷、密封面壓痕。這通常發生在新系統和大修之后的早期。這是最常見的失敗。在這種情況下,有必要去除清洗,去除渣,如密封表面的損壞,也應拋光;同時,打開底部的塞子,從平衡孔到渣的下蓋沖洗掉,沖洗管道。投運前,調節閥應全開,使介質在投運前流動一段時間。


2)外部沖刷法

對于一些易沉淀、含有固體顆粒的介質,采用電動閥,經常在節流孔、導塞處,可在閥蓋下對底部的氣體和蒸汽進行外部侵蝕。當閥門堵塞或卡住時,打開外部氣閥或蒸汽閥,在不移動調節閥的情況下完成清洗工作,使閥門正常工作。

以上就是電動閥遇到堵塞的情況的處理辦法。希望對你有所幫助。
