Detailed Description
Referring to fig. 1, the cold and hot self-adjusting valve body provided by the invention has a hot water inlet 2 at a first end of the valve body 1, a valve cap 3 mounted at a second end of the valve body 1, and a through hole formed in the valve cap 3. In the working state of the valve core, hot water flows in from a hot water inlet of the valve body 1 and then flows out from the valve cap 3 for use.
The inside flow isolating plate 4 that is equipped with of valve body 1, flow isolating plate 4 cuts apart into hot water passageway 5 and the mixed passageway 6 that all is parallel with valve body 1 axial direction with valve body 1 inner chamber, and hot water passageway 5 communicates with hot water inlet 2. The side wall of the valve body 1 is provided with a cold water inlet 7 communicated with the mixing channel 6, and the cold water inlet 7 is provided with a one-way valve 8.
The flow isolating plate 4 is provided with a communicating structure 40 for communicating the hot water channel 5 and the mixing channel 6. Under the working state of the valve core, hot water flows into the hot water channel 5 from the hot water inlet 2 and then enters the mixing channel through the communication structure 40; when the cold water inlet 7 is conducted, the cold water which is accessed by the cold water inlet 7 is mixed with the hot water in the mixing channel 6 and then flows out.
In this embodiment, the piston 9 is installed in the hot water passage 5, and the communicating structure 40 is located on the movement locus of the piston 9. The piston 9 is connected to the valve cap 3 by a memory spring 10. In this embodiment, after the valve core is opened and enters the working state, the water supply pipelines of the hot water inlet 2 and the cold water inlet 7 are all communicated, the water supply pressure of the hot water inlet 2 is greater than that of the cold water inlet 7, and the hot water pipeline connected with the hot water inlet 2 can be realized by setting the aperture of the hot water pipeline greater than that of the cold water pipeline connected with the cold water inlet 7. Therefore, after the valve core is opened, the water flow at the hot water inlet 2 presses the memory spring 10 to compress the memory spring 10, so that the communication structure 40 is completely unblocked, the interior of the valve body 1 is quickly filled with hot water, the water pressure in the valve body 1 rises, and the one-way valve is stopped. If the temperature of water input from the hot water inlet 2 is too high, the compressed memory spring slowly extends until the memory spring recovers to the original length, in the process, the piston 9 moves forwards to gradually block the communicating structure 40, so that the water pressure in the valve body 1 is reduced, the one-way valve 8 is opened, and the cold water inlet 7 is connected with cold water; and, with the gradual blockage of the communicating structure 40, the proportion of the hot water flow accessed by the hot water inlet 2 and the cold water flow accessed by the cold water inlet 7 is gradually reduced, so that the water temperature finally output by the valve core is adjusted.
In the present embodiment, the communicating structure 40 is a strip-shaped hole and is parallel to the axis of the valve body 1 so as to gradually block the communicating structure 40 along with the movement of the piston 9. And, the communicating structure 40 and the cold water inlet 7 are positioned on the same diameter of the cross-section circle of the valve body 1, so that the cold water and the hot water can be rapidly mixed and cooled.
Alternatively, the communicating structure 40 is a plurality of through holes dispersedly disposed on the flow partitioner 4. Therefore, the contact area of hot water and cold water is enlarged by diffusing flow through the through holes, so that rapid mixing and cooling are performed.

In this embodiment, the check valve 8 is a rubber valve, and the piston 9 is covered with a rubber ring.
In this embodiment, a flow dispersing plate perpendicular to the axial direction of the valve body 1 is arranged in the valve body 1, the flow dispersing plate is located between the valve cap 3 and the flow separating plate 4, and a plurality of through holes are formed in the flow dispersing plate. Thus, the mixed water flow flowing out from the mixing channel 6 is dispersed, so that the cold and hot uniformity can be further improved. The memory spring 10 penetrates the diffuser plate.
