[0003] However, ball valves face numerous severe challenges in high-temperature environments. On one hand, high temperatures cause thermal expansion of the ball valve materials. If the ball valve's structural design is inadequate, this expansion may generate excessive stress between internal components, leading to cracks and other damage, severely impacting the ball valve's service life and safety. On the other hand, high-temperature environments can also damage the ball valve's sealing performance, causing media leakage, which not only wastes resources and pollutes the environment but may also trigger safety accidents.

Some ball valves lack effective adaptive adjustment mechanisms and cannot cope with the material expansion caused by high temperatures; others have sealing structures that are prone to failure at high temperatures, making it difficult to guarantee reliable sealing performance. Therefore, developing an alloy ball valve that can operate stably in high-temperature environments and has good high-temperature resistance and crack prevention properties is of significant practical importance.

[0030] In order to better understand the above technical scheme, the above technical scheme will be described in detail in combination with the drawings of the specification and the specific embodiments.

[0031] Embodiment one

[0032] The utility model embodiment discloses a high-temperature-resistant anti-crack alloy ball valve.

[0043] Further, the connecting ring 145 is slidably connected to the inner wall of the connecting groove 144.

[0044] In a high-temperature environment, the valve core 12 expands due to heat and increases in volume, and pushes the valve seat 13, which is tightly combined with the valve core 12, to move away from the center of the valve core 12. The movement of the valve seat 13 drives the moving ring 142, which is fixedly connected with the valve seat 13, to slide in the moving groove 141, and the spring 143 is compressed.

[0045] The spring 143 generates a reaction force after being compressed, and the reaction force acts on the valve core 12 through the moving ring 142 and the valve seat 13, but due to the buffering effect of the elastic assembly 14, the valve core 12 and the valve seat 13 can still be tightly combined, so that the sealing performance is guaranteed.
