Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0028] The clamping assembly 2 comprises a clamping pipe 1, which is fixedly connected with the valve body 1. The outer surface of the clamping pipe 1 is sleeved with a sleeve 29. The outer surface of the clamping pipe 1 is provided with a receiving groove 26. The outer surface of the receiving groove 26 is sleeved with a clamping ring 292, which is fixedly connected with the sleeve 29. One end of the clamping ring 292 is fixedly connected with a clamping spring 291. One end of the clamping spring 291 is fixedly connected with one side of the inner wall of the receiving groove 26. The side, where the clamping pipe 1 and the clamping ring 292 are in contact, of the clamping pipe 1 is provided with a plurality of spherical grooves 24. The inner surfaces of the spherical grooves 24 are all provided with a plurality of balls 25. The inner surface of the clamping pipe 1 is sleeved with a clamping pipe 2. The outer surface of the clamping pipe 2 is provided with a ring groove 23 corresponding to the plurality of balls 25. When it is necessary to connect, the sleeve 29 is pushed to compress the clamping spring 291. The balls 25 enter the ring groove 23. After the sleeve 29 is loosened, the clamping spring 291 pushes the clamping ring 292 to make the balls 25 tightly cooperate with the ring groove 23, thereby realizing stable connection.

[0029] Specifically, the inner surface of the sleeve 29 is fixedly connected with two sliding blocks 293. The outer surface of the clamping pipe 1 is provided with sliding grooves 27 for cooperating with the two sliding blocks 293, which can effectively limit the sliding direction of the sleeve 29 and prevent the sleeve 29 from rotating circumferentially during installation or use, thereby further enhancing the stability and reliability of the clamping assembly 2.

[0030] As shown in Figures 1 to 5 , one end of the clamping pipe 1 is fixedly connected with a sealing ring 28, which can fill the gap at the connection position when the valve is connected with the pipeline, thereby improving the sealing performance of the connection position, effectively preventing fluid leakage and ensuring the normal work of the valve.

[0031] Furthermore, the diameter of the spherical groove 24 is greater than the diameter of the ball 25, and the opening size of the spherical groove 24 is smaller than the diameter of the ball 25, so as to prevent the ball 25 from falling out of the spherical groove 24, which not only ensures that the ball 25 can roll flexibly in the spherical groove 24 and cooperate with the ring groove 23 of the clamping pipe 2 to realize clamping, but also prevents the ball 25 from falling out of the spherical groove 24, thereby ensuring the normal use of the clamping assembly 2.

[0032] As shown in Figures 1 to 5As shown, the inner surface of the valve stem body 3 in the valve body 1 is provided with a cavity 8, the upper inner wall of the cavity 8 is fixedly connected with a top plate 9, the bottom end of the top plate 9 is fixedly connected with a buffer spring 7, the bottom end of the buffer spring 7 is fixedly connected with a buffer plate 10, the bottom end of the buffer plate 10 is fixedly connected with a temperature sensor body 4 through threads, the bottom end of the temperature sensor body 4 penetrates through the valve stem body 3 and extends into the valve body 1, which can effectively buffer the impact force of the fluid in the pipeline on the temperature sensor body 4, avoid damage or displacement of the temperature sensor body 4 due to excessive impact, and ensure that the temperature sensor body 4 stably and accurately measures the temperature of the medium in the valve body 1, providing reliable temperature data for system operation.

[0033] Notably, the outer surface of the buffer plate 10 is fixedly connected with two guide blocks 5, and the inner surface of the cavity 8 is provided with a guide groove 6 matched with the two guide blocks 5, which limits and guides the buffer plate 10 and the temperature sensor body 4, ensuring that the buffer plate 10 and the temperature sensor body 4 can only move linearly along the direction of the guide groove 6 when impacted, preventing them from shaking or shifting, and further improving the stability and measurement accuracy of the temperature sensor body 4.

[0034] As shown in Figures 1 to 5 The outer surfaces of the buffer plate 10 and the two guide blocks 5 are coated with sealing paint, which prevents the medium in the valve body 1 from leaking through the gap between the cavity 8 and the guide groove 6, avoids corrosion of the internal structure by the medium, protects the temperature sensor body 4 and the entire buffer structure, and prolongs its service life.

[0035] Working principle and process: The valve body 1 is connected to the pipeline through the clamping assembly 2, the sleeve 29 is pushed during installation, the clamping ring 292 is compressed by the clamping spring 291, the clamping pipe two 22 is inserted into the clamping pipe one 21, the sleeve 29 is loosened, the clamping spring 291 pushes the clamping ring 292, and the ball 25 enters the annular groove 23 of the clamping pipe two 22 to realize clamping. The temperature sensor body 4 in the valve stem body 3 is used to measure the temperature of the fluid in the valve body 1, when the fluid impacts the temperature sensor body 4, the buffer spring 7 buffers and protects the temperature sensor body 4 through the buffer plate 10, and the guide block 5 slides in the guide groove 6 to ensure the stability of the movement of the buffer plate 10.
