安装示意图 Installation diagram

安装阀门前，必须清洁管道避免磨损。安装阀门时，需要根据阀体上注明的流向安装。必须避免管道力 作用在阀体上。同时，应避免阀门振动。（必须在阀门上游安装过滤器）Before installing the valve, the pipeline must be cleaned to avoid abrasion. When installing the valve, it shall be installed according to the flow direction indicated on the valve body. Pipe forces must be avoided from acting on the valve body. At the same time, valve vibration shall be avoided. (filter must be installed upstream of the valve)
