阀门的启闭过程∶开启阀门时，要先旋转手轮，使塞子上升，与密封面脱离，再旋转手柄90°，使塞子的通道和阀体的通道相通，连到开启的。而开闭的过程是先旋转手柄90°，使塞子的通道和阀体的通道垂直，再旋转手轮，使塞子下降，连接密封 RETZ Process of opening and closing of thevalve. when opening the valve, first ofall, turn the hand wheel tomake the plug lifted and separated with the sealed surface,then turn the handle by 90 degree to connect the channel of plugto the channel of valve body, so that the valve is opened; when closing the valve, first of all, turn the handle by 90degree to make the channel of plug veertical to the channel of valve body, and then turn the hand wheel to descend the plug, so that the valve is closed.
