可以考虑打开阀门阀杆指示开度的地方,查看一下是否可以维修

如果蝶阀无法维修,又不能停下来更换,地方允许的话可以考虑带压钻孔,给这个蝶阀焊个旁路阀打开即可

最好发个图片,看看是否能修。能人力扳断的阀杆???还是要看看长啥样在发言:)

是执行机构坏了还是阀杆断了?能不能把阀杆焊接上或者用管钳打开?
Reply #62019-05-08
是阀杆里面还是外面?如果是执行机构就好搞,焊接已经可以满足,反正打开了一般也不需要关。如果是里面就只能换,循环水系统3、4个小时随便能换好吧!

楼主,还是发张图片吧。如果只是阀杆外部断,只需焊接或用管钳;如果是内部坏,就停下来换吧。

如果不停工,只能带压在线钻孔,在蝶阀前后增加阀门,然后打开阀门。
