Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heating, in particular to an electric heating actuator valve core with temperature and flow balance. BACKGROUND

[0002] In actual use, the heating distribution water collector on the market often causes uneven temperature in each branch. In the case of the same length of each branch pipe, the branch closest to the main water supply pipe has the highest temperature, and the branch farthest from the main water supply pipe has the lowest temperature. The reason is that the branch closest to the main water supply pipe has the smallest resistance and the largest flow, and the branch farthest from the main water supply pipe has the largest resistance and the smallest flow. In the actual process of laying the floor heating pipe, the length of each branch pipe is not the same, which causes the complexity of uneven temperature difference in each branch, and is also a problem that has plagued the heating industry.
