Problems solved by technology

[0005] The disadvantage of this floor heating mixing device is that the three-way mixing valve can only realize the two functions of "using all the low temperature water for mixing" and "returning all the low temperature water", and cannot adjust the low temperature water according to actual requirements. The proportion of mixed high-temperature influent water; the structure of the whole water mixing device is complex and the cost is high

Embodiment 1

[0032] like figure 1 , figure 2 and image 3 As shown, the present embodiment is a self-adjusting backflow three-way valve, which includes a valve body 1 with a valve cavity 11 inside. Connected water supply inlet 12, water supply outlet 13 and return water inlet 14. The water supply inlet 12 also has a heat network 200 for connecting to a heat source. The heat network 200 water supply pipe interface 15, the water supply outlet 13 has a user water supply pipe interface 16 for connecting the water separator 300, and the return water inlet 14 has a water supply pipe interface for The user return pipe interface 17 connected to the water collector 500 ; the water supply pipe interface 15 of the heating network 200 , the user water supply pipe interface 16 and the user return pipe interface 17 are all integrally formed with the valve body 1 .

[0033]In this embodiment, one end of the valve chamber 11 is closed, and at the other end of the valve chamber 11, the valve body 1 is ...

Embodiment 2

[0046] like Image 6 As shown, in this embodiment, a water mixing center for automatically adjusting backflow includes a water mixer 100, which is the three-way valve for automatically adjusting backflow in Embodiment 1, and the water supply inlet 12 of the water mixer 100 is connected to the The heating network 200 is connected, the water supply outlet 13 is connected with the water distributor 300, and the water distributor 300 is connected with the water collector 500 through several water distribution pipes 400, and each water distribution pipe 400 is distributed in each user's room; the water collector 500 The water outlet end of the water outlet is respectively connected with the heat network 200 and the return water inlet 14 of the water mixer 100 through the return water tee 600 .

[0047] The water outlet end of the water collector 500 is also provided with a temperature sensor 700 for detecting the return water temperature, and a drive mechanism (not shown) connected...

Abstract

The invention discloses an automatic adjustment backflow three-way valve and a water mixing center thereof. The three-way valve comprises a valve body, wherein a valve cavity is arranged in the valvebody. A supplied water inlet, a supplied water outlet and a return water inlet which communicate with the valve cavity are arranged on the valve body and are sequentially arranged in the circumferential direction of the valve body by being spaced by 90 degrees. A valve element is rotationally mounted in the valve cavity and is in sealed fit with the inner wall of the valve cavity. The valve element is provided with a direct water supply position used for completely blocking the return water inlet, a mixed water supply position used for partially blocking or not blocking the return water inletand a water closing position used for completely blocking the return water inlet. According to the automatic adjustment backflow three-way valve, the blocking degree of the valve element to the returnwater inlet can be adjusted by adjusting the rotating angle of the valve element, and therefore the mixing quantity of low-temperature water is controlled, and the aim of precisely adjusting the final supplied water temperature is achieved.

Description

technical field [0001] The invention belongs to the technical field of heating facilities, and in particular relates to an automatic adjustment backflow three-way valve and a water mixing center thereof. Background technique [0002] Floor heating is a very widely used heating facility. At present, the heat medium of floor heating is usually hot water. The temperature of the hot water output by the heating network is the same, but the heating parameters of each heating user connected to the heating network are different. are not the same, so it is necessary to be able to adjust the heating parameters at any time. [0003] In order to solve the above-mentioned problems, most existing heating systems of residential buildings are required to be equipped with a constant temperature mixing center capable of realizing a constant water temperature function. For example, the Chinese utility model patent with the publication number CN203642300U also discloses a ground heating mixing...
