Further, a third connecting shaft 1410 and a second connecting shaft 1411 are sequentially arranged on the pressure thermometer 131, a fourth gear 1413 and a third gear 1412 are respectively arranged on the third connecting shaft 1410 and the second connecting shaft 1411, a fifth gear 1414 is arranged on the synchronizing shaft 141, wherein the fourth gear 1413 is meshed with the fifth gear 1414, the fourth gear 1413 is meshed with the third gear 1412, the diameters of the fifth gear 1414, the fourth gear 1413 and the third gear 1412 are sequentially increased, the second gear 146 is arranged on the third connecting shaft 1410, so that when the synchronizing shaft 141 rotates, the driving force required for driving the pressure thermometer 131 and the mounting seat 134 to rotate can be reduced through the speed reduction transmission of the fifth gear 1414, the fourth gear 1413 and the third gear 1412, the temperature measuring pointer can be driven to stably rotate when the pressure thermometer 131 rotates, the temperature measuring pointer can be used for flow regulation and control, and otherwise, the diameters of the third gear 1412, the fourth gear 1413 and the fifth gear 1414 are gradually decreased and accelerated, the water flow is increased to wash the temperature bulb 133 to drive the pressure type thermometer 131 to rotate, and the stable flow regulation and control of the temperature bulb 133 are ensured.

The outer side of the lantern ring 1415 is sleeved with the outer cover 15, the outer cover 15 covers the outer sides of the lantern ring 1415 and the gears and rotates synchronously with the pressure type thermometer 131 to provide sealing protection for the gears and tooth grooves, and dust and impurities on the surface are accumulated to influence stable transmission of the gears.

And then through the balanced valve that sets up including temperature acquisition module 13 and actuating mechanism 14, can real-time supervision return water temperature on hot user's wet return to according to the direct and automatic adjustment pipeline aperture size of return water temperature, abandoned data transmission to the terminal and through the mode of terminal control, effectively avoided the stable regulation and control of aperture under the untimely or signal terminal condition of data transmission, guarantee that the automatic and timely stable balanced regulation and control of secondary network uses.
