电动调节球阀
ELECTRIC REGULATING BALL VALVE
应用
电动调节球阀广泛用于中央空调、采暖、水处理、工业加工行业等系统的流体控制。执行器接收标准的调节型号或三态浮点信号，将球体旋转至指定位置。
Apply
Electric ball valve is widely used in central air conditioning, heating, water treatment, industrial processing industry and other systems of fluid control. The actuator receives a standard adjustable type or tri-state floating-point signal and rotates the sphere to the specified position.
工作原理
电动调节球阀由角行程执行器进行驱动，执行器通过接收BA系统的调节型信号(0-10V或4-20mA)或三态浮点型信号来驱动阀门改变球体与阀座之间的流通面积，从而控制通过阀门的流量，实现自动调节功能。
Working principle
The electric adjustable ball valve is driven by the angular stroke actuator, which drives the valve to change the flow area between the ball and the seat by receiving the adjustment signal of the BA system (0-10V or 4-20mA) or the three-state floating point signal, so as to control the flow through the valve and realize the automatic adjustment function.

安装说明
由于球阀和驱动器是分体式的，可在管道上装好球阀后再安装驱动器。为了调试方便，应了解球体在阀体内的启闭状况，因此阀杆顶端平面刻有一字槽，其方向与球体通孔方向一致。另外，在安装驱动器时，驱动器方孔内的轴销要与阀杆的唯一性安装记号槽方向一致，安装时请按阅体标示的流向方向安装；在所配用型号驱动器的包装盒内的说明书上，详细说明了安装连接方法。球阀可水平装，也可以垂直安装，但不能倒转朝下安装。
Installation instructions
Since the ball valve and driver are split, the driver can be installed after the ball valve is installed in the pipe. In order to facilitate debugging, the opening and closing condition of the ball in the valve body should be understood, so the top plane of the valve stem is engraved with a slot, and its direction is consistent with the direction of the ball through the hole. In addition, when installing the driver, the shaft pin in the square hole of the driver should be in the same direction as the unique installation slot of the valve stem. Please install the shaft in the direction of the flow marked by the reading body during installation; The installation and connection methods are described in detail on the instructions contained in the box of the model driver. Ball valve can be installed horizontally, can also be installed vertically, but can not be inverted downward installation.
