干氯气系统,使用氯气专用阀(和截止阀结构类似),近两年出现拧不动的情况比较频繁,少则三个月,多则一年,阀门就慢慢出现“卡死”的情况了,DN150和DN200的阀门刚开始直接用手都很轻松,而后一个人需要用F扳手,到最后三个人用F扳手都无法拧动了,换了三个厂家的阀,均有类似情况出现,到底是什么原因造成的,还请管阀区的朋友予以解惑,谢谢!

信息最好再补充一下,最好有产品图片和铭牌,以了解产品结构特性。是波纹管型还是普通型,用的什么填料,阀门是什么材质,特别是阀杆和内件。 一般情况下,首先考虑在使用过程中产品出现了材质腐蚀(是否有水分进入阀门内部等),其次考虑产品结构是否合理。

换成波纹管的吧,普通的容易锈死

刘总有好阀门,不妨介绍一下。

氯气系统大多不都是波纹管截止阀么
