A limit spring 3 is sleeved on the surface of the valve core body 2, and a bearing plate 17 is sleeved on the lower end of the valve core body 2. A locking rod 18 is fixedly installed on both sides of the bottom of the bearing plate 17.

[0024] A top plate 4 is fixedly installed on the top of the thermostat body 1. Positioning plates 5 are provided on both sides of the top of the top plate 4. Vertical rods 8 are fixedly installed on the top of the positioning plates 5. A horizontal plate 9 is fixedly installed on the top between the two vertical rods 8. A fixing sleeve 10 is fixedly installed at the center of the top of the top plate 4. The lower end of the valve core body 2 passes through the fixing sleeve 10 and the top plate 4 and extends into the interior of the thermostat body 1. A fastening sleeve 11 is fitted onto the surface of the fixing sleeve 10. Vertical plates 12 are fixedly installed on both sides of the fastening sleeve 11. A support spring 13 is welded to the inner side of the upper end of the vertical plate 12. An arc-shaped retainer 14 is snapped into the inner end of the support spring 13. The arc-shaped retainer 14 is snapped into the upper surface of the valve core body 2.

[0025] Both sides of the top of the top plate 4 are provided with snap-fit ​​grooves 7, and snap-fit ​​blocks 6 are snapped into the inside of the snap-fit ​​grooves 7. The top of the snap-fit ​​blocks 6 is fixedly installed with the bottom of the positioning plate 5, and the positioning plate 5 is connected to the top plate 4 by bolts.

[0026] Through the above technical solution, the snap-fit ​​groove 7 can support and install the snap-fit ​​block 6 at the bottom of the positioning plate 5, and at the same time increase the firmness of the positioning plate 5 after it is installed on the top of the top plate 4.

[0027] A fastening plate 15 is fixedly installed on the right side of the bottom of the top plate 4 and on the side close to the thermostat body 1. The top of the fastening plate 15 is connected to the top plate 4 by bolts.

[0028] By using the above technical solution, by adding a fastening plate 15 between the bottom of the top plate 4 and the thermostat body 1, the bottom of the top plate 4 can be reinforced to prevent it from shaking.

[0029] A sealing ring 16 is snapped into the center of the top of the horizontal plate 9, and one end of the valve core body 2 is located inside the sealing ring 16.

[0030] By adding a sealing ring 16 to the top of the horizontal plate 9, the sealing between the valve core body 2 and the horizontal plate 9 can be increased, and no large gap will occur when moving up and down.

[0031] The bottom of the horizontal plate 9 is fitted to the top of the limiting spring 3, and one end of the valve core body 2 is movably connected to the through position of the horizontal plate 9.

[0032] By using the above technical solution, the limiting spring 3 and the horizontal plate 9 are fixed together, which avoids the limiting spring 3 from shifting slightly when it is squeezed, and ensures the balance of the limiting spring 3 when it contracts and moves.

[0033] Both sides of the top of the horizontal plate 9 are provided with through slots, and one end of the vertical plate 12 is located inside the through slot and is slidably connected.

[0034] Through the above technical solution, the through groove can limit one end of the vertical plate 12 and ensure that the vertical plate 12 remains balanced when moving up and down.

[0035] The inside of the arc-shaped ferrule 14 is coated with an anti-corrosion coating, and the surface of the anti-corrosion coating is provided with a wear-resistant paint layer.

[0036] Through the above technical solution, the anti-corrosion coating inside the arc-shaped ferrule 14 can protect the surface of the valve core body 2, and the additional wear-resistant paint layer can prevent internal corrosion. After the valve core is attached to one end, it will not cause friction damage to its surface.

[0037] The lower end of the snap-fit ​​rod 18 is snapped and fixed inside the thermostat body 1, and the bearing plate 17 is fastened and snapped onto the surface of the valve core body 2.

[0038] By using the above technical solution, the lower end of the valve core body 2 can be limited and supported by the snap-fit ​​rod 18 inside the thermostat body 1, and the firmness of the lower end of the valve core body 2 after installation inside the thermostat body 1 can be ensured.

[0039] A sealing gasket is fitted onto the middle of the bearing plate 17 and onto the surface of the valve core body 2, and the sealing gasket is arc-shaped and securely fastened to the surface of the valve core body 2.

[0040] By adding a sealing gasket inside the bearing plate 17, the surface of one end of the valve core can be protected, and the friction force can be increased, so that the bearing plate 17 will not fall off after installation.

[0041] The working principle of this invention is as follows: the valve core is installed by snap-fit, so that one end is installed inside the thermostat body 1, which makes it easy to disassemble and replace later. At the same time, the upper end of the valve core is supported by multiple structures to keep it balanced during operation and movement, which can effectively prevent the valve core from tilting and thus improve the working efficiency of the thermostat.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
