Triplet electro-heat execution valve and terra warm water mixing device

Abstract

The invention belongs to the ground heating water mixing device technical field. The three-way electric heat execution valve of the invention comprises a valve body, a valve core assembly and an electric heat power assembly. The valve body is provided with a water inlet, a by-pass port, a water outlet and a mounting port; the valve core assembly comprises a valve core; the electric heat power assembly can push the valve core to move; the valve body is also provided with a main through port communicating the water inlet and the water outlet and an auxiliary through port communicating the water inlet and the by-pass port; the valve core comprises a valve core bar, a limiting member arranged on the valve core bar, a main seal plate capable of blocking the main through port in the valve body, and an auxiliary seal plate capable of blocking the auxiliary through port in the valve body. The ground heating water mixing device provided by the invention adopts the three-way electric heat execution valve capable of conveniently controlling the water discharge flow rate and the backwater flow rate. The temperature control valve has the advantages of convenient control of hot water return and discharge flow rate, quicker response to temperature control and higher temperature control accuracy. The ground heating water mixing device has the advantages of capability of making full use of hot water heat energy, quicker response to temperature control and higher temperature control accuracy.

Description

technical field [0001] The invention belongs to the technical field of home heating, and in particular relates to a method and device for controlling the temperature of mixed water for floor heating. Background technique [0002] Low-temperature hot water floor radiant heating, commonly known as floor heating, is replacing radiator heating due to its comfort and energy saving, and is gradually becoming the mainstream heating method. According to statistics, more than 90% of new buildings in some developed countries in Germany, Japan and Northern Europe adopt floor heating for heating. [0003] Low-temperature hot water floor radiant heating, according to relevant requirements and considerations of comfort, generally requires the temperature of hot water entering the floor heating pipe to be below 60°C, if the temperature is too high, it will affect the comfort and service life of the pipe, and will cause the room to overheat The thermal energy waste of window regulation.

Problems solved by technology

The disadvantage of this kind of household floor heating mixing water device is: this kind of floor heating mixing water device uses a four-way fixed with a pressure switch at the upper end and a regulating valve with a structure that cannot be completely closed at the lower end as the water volume adjustment mechanism, and its structure is relatively complicated. The cost is high; in addition, there are also the disadvantages of slow flow rate adjustment and poor temperature control accuracy

[0005] Other existing technologies also use mechanical self-operated temperature control two-way or three-way valves for flow control, but they all have the disadvantages of slow temperature control response speed and poor temperature control accuracy.
