Description

Technical Field

The heat exchange tube is also provided with a regulating mechanism for regulating the liquid flow. The utility model adjusts the flow of the medium in the heat exchange tube by setting an regulating mechanism, specifically, by rotating the knob, driving the rotating rod to rotate, and then rotating the ball center. When the through hole of the ball center is parallel to the flow direction of the medium, the medium can pass through at a larger flow rate. When the through hole of the ball center is crossed or perpendicular to the flow direction of the medium, the flow rate of the medium is reduced, thereby realizing flow regulation.
