Specifically, the heat exchange device 3 is arranged on one side of the valve body 1 close to an air quick valve 19, so that the high-temperature air in the flow channel lining pipe can be subjected to heat exchange. In the design, the inlet air lining pipe 25 and the outlet air lining pipe 26 are always filled with high-temperature air. When the high-temperature quick valve is in a non-working state, the heat exchange device 3 is opened, the external cooling gas enters the exchange cavity 9 through the air inlet proportional adjusting valve 4, then enters the heat exchange through pipe 6 through the communication port 10 of the exchange cavity 9, so that the heat exchange through pipe 6 is subjected to heat exchange with the high-temperature air in the flow channel lining pipe, the high-temperature air is taken out through the heat exchange through pipe 6 and is discharged to the outside of the valve body 1 through the air outlet proportional adjusting valve 17, so that the heat exchange is realized.

[0025] Further, the heat exchange pipe group 5 is arranged in a three-layer structure, the heat exchange pipe group 5 comprises the heat exchange through pipe 6, the heat exchange sleeve pipe 7 and the water cooling sleeve pipe 8, the heat exchange sleeve pipe 7 is arranged on the outer surface of the heat exchange through pipe 6, the water cooling sleeve pipe 8 is arranged on the outer surface of the heat exchange sleeve pipe 7, the exchange cavity 9 is formed between the heat exchange sleeve pipe 7 and the heat exchange through pipe 6, a plurality of communication ports 10 are arranged on one end of the heat exchange through pipe 6 close to the valve body 1, and the heat exchange through pipe 6 is communicated with the exchange cavity 9 through the communication ports 10.

The gap can provide space for the deformation of the heat exchange pipe 6 after the heat exchange pipe 6 is heated and expanded, so as to avoid the extrusion deformation of the part of the heat exchange pipe 6 close to the valve body 1 due to the lack of expansion space.

[0027] Further, the pipe wall of the heat exchange sleeve 7 extends away from the center position of the heat exchange sleeve 7 to form an adjusting pipe 16, the adjusting pipe 16 is arranged through the pipe wall of the water cooling sleeve 8, the air inlet proportional adjusting valve 4 is arranged at one end of the adjusting pipe 16 away from the heat exchange sleeve 7, and the air inlet proportional adjusting valve 4 is communicated with the heat exchange sleeve 7 through the adjusting pipe 16.

[0029] Further, the valve body 1 is arranged as a double valve structure in which the high-temperature stop valve 18 and the air quick valve 19 are connected together, so that the flow channels 2 of the high-temperature stop valve 18 and the air quick valve 19 are communicated, a flow channel lining pipe 21 made of a nickel-based alloy material is arranged in the communicated flow channels 2, and a double-layer heat preservation structure 20 is arranged on the flow channel lining pipe 21, so that the air in the flow channel lining pipe 21 can be effectively preserved and the temperature loss is reduced, the double-layer heat preservation structure 20 is a flow channel sleeve 22 arranged on the flow channel lining pipe 21 and a heat preservation material, the flow channel sleeve 22 is arranged outside the flow channel lining pipe 21, a first heat preservation cavity 23 is formed between the flow channel sleeve 22 and the flow channel lining pipe 21, a second heat preservation cavity 24 is formed between the flow channel sleeve 22 and the inner wall of the flow channel 2, and the first heat preservation cavity 23 and the second heat preservation cavity 24 are both filled with the heat preservation material.

[0030] Further, the flow channel liner 21 in the flow channel 2 is provided in a multi-section structure, the flow channel liner 21 near the high-temperature stop valve 18 is an air inlet liner 25, the flow channel liner 21 near the air quick valve 19 is an air outlet liner 26, the air inlet liner 25 is in communication with the air outlet liner 26, and a blowout prevention connecting structure 27 is arranged between the air outlet liner 26 and the air inlet liner 25, and the two ends of the blowout prevention connecting structure 27 are correspondingly connected to the air inlet liner 25 and the air outlet liner 26.

Specifically, by arranging the blowout prevention gap 28, a deformable space can be provided for the air inlet liner 25 and the air outlet liner 26 in a super-high-temperature environment for a long time, so as to prevent the two from being extruded and deformed in a close state; and the blowout prevention gap 28 can also limit the heat preservation material in the first heat preservation cavity 23, since the blowout prevention gap 28 is in communication with the first heat preservation cavity 23 to form a bending structure, so that the heat preservation material cannot be blown out towards the air outlet liner 26 due to excessive air pressure.

[0031] Specifically, a transition connecting structure is further arranged on the flow channel sleeve 22, the transition connecting structure includes a first transition connecting structure 29 and a second transition connecting structure 30, the first transition connecting structure 29 extends obliquely from one end of the air inlet liner 25 near the air outlet liner 26 towards the cavity wall of the flow channel, the second transition connecting structure 30 extends obliquely from one end of the air outlet liner 26 near the air inlet liner 25 towards the inner wall of the flow channel, and the first transition connecting structure 29 and the second transition connecting structure 30 are both connected to the inner wall of the flow channel.
