Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0029] It should be noted that the terms "first," "second," and so on in the specification and claims of this utility model and the aforementioned drawings are used to distinguish similar items and are not necessarily used to describe a specific order or precedence. In addition, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0030] like Figures 1 to 4 As shown in the figure, a Korean-style ball valve with flameout protection is provided in the present invention, comprising a copper valve body 1, a regulating assembly, a solenoid valve 3 and a switch assembly.

[0031] The copper valve body 1 is provided with an air inlet and an air outlet, the air inlet and the air outlet are located on the same straight line, and the air outlet can be installed with nozzles of different specifications according to different air sources. A pressure cap 5 is connected to the air inlet.

[0032] A first cavity 18 , a second cavity 19 and a third cavity 20 that are interconnected are provided in the copper valve body 1 . The air inlet is connected to the third cavity 20 , and the air outlet is connected to the first cavity 18 .

[0033] The adjusting assembly is connected to the first cavity 18 and includes a push rod 4, a spring 15 and a second O-ring 14. The push rod 4 is connected to the copper valve body 1 through the spring 15. A second O-ring 14 is provided between the push rod 4 and the inner wall of the first cavity 18. By moving the push rod 4 downward, the solenoid valve 3 can be opened. When the shut-off function of the solenoid valve 3 fails, emergency treatment is performed to ensure that the shut-off function is in a smooth state. The spring 15 has a buffering effect on the push rod 4, and the second O-ring 14 can play a sealing role to prevent leakage.

[0034] The solenoid valve 3 is connected to the second cavity 19, with its installation orientation at a 90-degree angle to the air outlet. The solenoid valve 3 is secured to the copper valve body 1 by screws 16 and positioned within the second cavity 19. Screws 16 enhance the stability of the connection between the solenoid valve 3 and the copper valve body 1. An external connector 17 is provided at the end of the solenoid valve 3 for connecting a thermocouple.

[0035] The switch assembly is connected to the third cavity 20, and the switch assembly includes a handle 2, a rotating shaft rod 12 and a ball core 9. The handle 2 is connected to the ball core 9 through the rotating shaft rod 12. The ball core 9 is confined in the third cavity 20. By rotating the handle 2, the ball core 9 can be driven to rotate through the rotating shaft rod 12 to realize the opening or closing of the ball valve.

[0036] The handle 2 is sleeved on the shaft rod 12 , and a nut 13 is connected to the end of the shaft rod 12 . The nut 13 can improve the connection stability between the handle 2 and the shaft rod 12 .

[0037] A first O-ring 11 is provided between the rotating shaft 12 and the copper valve body 1 to seal and prevent leakage.

[0038] A first sealing gasket 8 and a second sealing gasket 10 are provided between the core 9 and the inner wall of the third cavity 20 . The first sealing gasket 8 and the second sealing gasket 10 can improve the stability and reliability of the core 9 during operation and prevent leakage.

[0039] The adjustment assembly is connected to the copper valve body 1 through a locking assembly. The locking assembly includes a pin 7 and a slot 6. The slot 6 is arranged in a 7-shaped structure on the copper valve body 1. The pin 7 is connected to the push rod 4 and moves along the slot 6. The design of the pin 7 and the slot 6 can control the pressing stroke of the push rod 4 while preventing the push rod 4 from rotating. When pressed to the bottom, the push rod 4 can be rotated and moved, so that the push rod 4 is always in the open state. At this time, the solenoid valve 3 is always open, which is used for temporary emergency use when the solenoid valve 3 fails to work. Under normal conditions, the locking assembly is not opened.

[0040] The above structure design not only realizes the flameout protection function, but also allows for emergency treatment in the event of damage through the adjustment component and the locking component, so that the flameout protection is unobstructed and does not affect normal use.

[0041] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications based on the present invention to achieve substantially the same technical effects are included within the scope of protection of the present invention.
