[0014] (III) Beneficial effects

[0015] Compared with the prior art, the present invention provides a heating temperature balance control valve, which has the following beneficial effects:

[0016] 1. The heating temperature balancing control valve can discharge external hot water and cold water into the connecting pipe for mixing through the hot water pipe and the cold water pipe, and discharge them through the outlet pipe, and then through the heat-receiving material.

The positioning rod 14 and the rack 13 are movably sleeved with the same positioning ring 15, and the positioning ring 15 is fixedly connected to the circular tube 6, which can improve the stability of the movement of the circular plate 7 and the rack 13.

[0027] The side wall of the connecting tube 1 is symmetrically provided with two through holes matching the circular tube 6 , and a rubber plug 16 is movably embedded in the through holes, which can facilitate the addition of lubricating oil to the parts inside the circular tube 6 and improve the transmission effect of the internal parts.
