[0027] As a technical optimization solution of the present invention, by providing the sealing ring 15, the drainage component 3 can be made more sealed to avoid water leakage.

[0028] refer to Figure 2 A filter screen 16 is arranged on the right side of the inner cavity of the valve body 1 , and the filter screen 16 is used in conjunction with the valve body 1 .

[0029] As a technical optimization solution of the present invention, by providing the filter 16 , the water flow inside the valve body 1 can be filtered to prevent the valve body 1 from having excessive impurities inside.

[0030] refer to Figure 2 A spiral tooth 17 is provided on the right side of the surface of the valve body 1 , and the spiral tooth 17 is used in conjunction with the valve body 1 .

[0031] As a technical optimization solution of the present invention, the spiral teeth 17 are provided so that the right side of the surface of the valve body 1 can be more firmly connected to the external pipeline, thereby increasing the convenience of connection.

[0032] refer to Figure 3 A sealing recess 18 is provided at the bottom of the valve stem 11, and the sealing recess 18 is used together with the valve stem 11.

[0033] As a technical optimization solution of the utility model, by setting the sealing concave block 18, the valve stem 11 can be fine-tuned up and down more stably, thereby enhancing its sealing performance.

[0034] refer to Figure 3 Both sides of the bottom of the inner cavity of the drainage component 3 are provided with protrusions 19, and the protrusions 19 are used in conjunction with the sealing recessed blocks 18.

[0035] As a technical optimization solution of the utility model, the provision of the protrusion 19 can improve the sealing performance of the valve stem 11 and avoid water leakage.

[0036] The working principle and use process of the utility model are as follows: first, water flows through the interior of the valve body 1 to the interior of the temperature-sensitive stop valve 2. When the memory alloy spring 19 inside the temperature-sensitive stop valve 2 senses cold water, it will contract. When the memory alloy spring 19 contracts, the spring 18 will push the valve stem 7 downward, and then the mounting seat 5 will also move downward through the pressure difference to block the water inlet. On the contrary, when encountering warm water, the memory alloy spring 19 will expand, and its expansion force will be greater than the spring 18, loosening the mounting seat 5 to allow it to flow, and then the cold water remaining in the valve body 1 will contract through the memory alloy spring 2 12. After the memory alloy spring 2 12 contracts, the spring 2 13 will lift the valve stem 2 11 upward, and its drain port will leak out. Under normal temperature, the elastic force of the memory alloy is greater than that of an ordinary spring, and when it is lower than the set temperature, the elastic force of the memory alloy is less than that of an ordinary spring, and the remaining cold water will be discharged through the drain assembly 3, so that the valve body 1 can be opened and closed according to the temperature of the water flow.

[0037] In summary: the antifreeze valve with a temperature control device changes the traditional phenomenon that the valve body cannot be opened and closed according to the temperature of the water flow. The valve stem 7, the memory alloy spring 9 and the spring 8 are used for opening and closing. The opening and closing of the valve body 1 can be controlled according to the temperature of the water flow, and the service life of the antifreeze valve will not be limited.
