進口進口電動調節球閥安裝說明 installation instructions
由於球閥和驅動器是分體式的，可在管道上裝好球閥後再安裝驅動器。為了除錯方便，應了解球體在閥體內的啟閉狀況，因此閥桿頂端平面刻有一字槽，其方向與球體通孔方向一致。另外，在安裝驅動器時，驅動器方孔內的軸銷要與閥杆的性安裝記號槽方向一致，安裝時請按閥體標示的流向方向安裝；在所配用型號驅動器的包裝盒內的說明書上，詳細說明了安裝連線方法 retz ball valve and the driver are split, the driver can be installed after the ball valve is installed on the pipeline. in order to facilitate debugging, it is necessary to understand the opening and closing conditions of the ball in the valve body. therefore, the top plane of the valve stem is engr**ed with a slot, whose direction is consistent with the direction of the ball through hole. in addition, when installing the driver, the shaft pin in the square hole of the driver shall be consistent with the direction of the unique installation mark groove of the valve stem. please install it according to the flow direction marked on the valve body; the installation and connection methods are described in detail in the instructions in the packaging box of the matched driver. the ball valve can be installed horizontally or vertically, but cannot be installed upside down.
球閥可水平裝，也可以垂直安裝，但不能倒轉朝下安裝 the ball valve can be installed horizontally or vertically, but cannot be installed upside dow
