阀门阀体上标示的箭头方向表示阀门的承压方向,一般被工程装置公司作为介质流向符号过错装置发生走漏乃引发管路事故;
The arrow direction marked on the valve body indicates the pressure bearing direction of the valve, which is generally used as the medium flow direction symbol by the engineering device company. The leakage of the wrong device and even pipeline accidents are caused;
承压方向是指该阀门应用于管路工况后的封闭状态下,阀体箭头方向为引荐接受压力的方向,如若过错装置,则或许出现阀门封闭不严的走漏毛病现象发生。超达的软密封球阀一般是双向密封的,一般不标出箭头,金属硬密封球阀能够做到双向密封,但仍是会有一个方向的密封功能仍是较好一点的,所以也会有标出箭头,这就是指引荐阀门承压方向,能够先咨询下客户的意见。
If the valve is not closed tightly under the recommended working condition, the direction of the pressure bearing device may be the direction of the valve. If the arrow is not closed tightly under the recommended working condition, it refers to the direction of the valve. Chaoda's soft seal ball valve is generally two-way sealed, and the arrow is generally not marked. The metal hard seal ball valve can achieve two-way sealing, but there will still be one direction, and the sealing function is still better. Therefore, the arrow will also be marked, which refers to the pressure bearing direction of the valve. You can consult the customer first.
带有标示箭头的硬密封蝶阀在管道的不同方位,其箭头的方向与介质流向均是不一样的,如在泵房内水泵的出水端,则阀体的箭头与介质流向是相反的,如在水泵的入水端,则箭头与介质流向是共同的,如装置于主管路上的,则箭头一般顺应介质流向等,具体要看工况及装置方位再定。
For the hard seal butterfly valve with marked arrow, the arrow direction and medium flow direction are different in different directions of the pipeline. For example, at the outlet end of the pump in the pump room, the arrow of the valve body is opposite to the medium flow direction. For example, at the inlet end of the pump, the arrow and medium flow direction are common. If it is installed on the main pipeline, the arrow generally conforms to the medium flow direction. The specific situation depends on the working condition and device orientation.
