Description

Technical Field

[0001] The utility model relates to the technical field of heat measurement, in particular to a control valve system for optimizing heat network zoning. Background Art

[0002] The existing heating network zoning control valve has a single function of only locking the fluid passage. With the use of the equipment and the oxidation of the materials over time, the residual substances such as rust will cause blockage in the key parts and pipelines of the zoning control valve. Once blocked, it will affect the function and normal use of the zoning control valve. Similarly, if the user of the heating pipeline releases water privately, it will destroy the entire heating circulation system and fail to meet the heating needs of each floor and each household. Since the control valve is not equipped with a temperature sensor and cannot detect the heating temperature, the valve cannot be automatically closed when the heating season ends early, wasting water resources.
