Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention so that the technical solution of the present invention can be more easily understood and grasped, and should not be construed as limiting the present invention.

Example (b):

a three-way ball valve core based on thermodynamic effect is disclosed, referring to fig. 1, fig. 2 and fig. 3, comprising a main sphere 1, a right-angle pipeline 2 arranged in the main sphere 1, and a second channel 3 arranged between the outside of the right-angle pipeline 2 and the inside of the main sphere 1, wherein the inlet of the second channel 3 is in the same direction as the inlet of the right-angle pipeline 2, and the outlet of the second channel 3 is in the opposite direction to the outlet of the right-angle pipeline 2. D1 in fig. 3 represents the flow direction of the water flow on the right-angle pipe 2; d2 in fig. 3 represents the flow direction of the water flow on the second passage 3. An adjusting cover 4 is fixedly connected to an inlet of the right-angle pipe 2, and the adjusting cover 4 comprises a fixing part 41 fixedly installed on the right-angle pipe 2 and a thermal bimetal part 42 for adjusting water flow resistance.

Bimetallic strip is a commercially available bimetallic strip, which is a composite material made of two (or more) layers of metal or alloy components having different coefficients of thermal expansion. One type of precision alloy is formed by firmly bonding two (or more) layers of metals or alloys having different coefficients of thermal expansion as constituent layers. A component layer in the thermal bimetal has a low thermal expansion coefficient and is a passive layer; the other component layer has a high coefficient of thermal expansion and is the active layer.

The main ball body 1 is used as a valve core structure and is suitable for being assembled on a three-way ball valve. Because have right angle pipeline 2 and second passageway 3 in the main spheroid 1, can realize the reposition of redundant personnel effect from this, can also play the effect of opening and close in addition. In addition, because the inlet of the right-angle pipeline 2 is provided with the adjusting cover 4, the deformation of the adjusting cover 4 is influenced by the temperature change of the medium, and the resistance influence condition of the adjusting cover on the flow velocity of the medium is changed by the deformation of the adjusting cover 4, so that the purpose of adapting to the temperature change to make flow self-adaptive change is achieved.

And the threaded connection mode is adopted, so that the assembly and the disassembly are convenient. The welding mode is adopted, so that the reliability and firmness of connection can be effectively improved. The interference fit mode is adopted, so that the assembly is convenient, and the process is simplified.

The fixing portion 41 is annular, the thermal bimetal component 42 is strip-shaped, and the plurality of thermal bimetal components 42 are uniformly distributed on the periphery of the fixing portion 41 in the circumferential direction. The fixing portion 41 and the thermal bimetal 42 are connected by caulking or integrally. The annular fixing portion 41 is mainly adapted to the right-angle pipe 2, and the strip-shaped thermal bimetal 42 can improve the resistance surface. The circumferential uniform distribution mainly reflects the uniform degree of stress.

The thermal bimetal member 42 is bent and deformed in the water flow direction by heat. Since the thermal bimetal 42 is deformed after being heated, the resistance to the flow of water is reduced, and the flow rate of hot water is increased, whereas the relative resistance is large and the flow rate is reduced in the case of cold water.
