[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] The preferred embodiment of the gas sealing device for high temperature furnace provided by the utility model is as follows Figures 1 to 5 As shown: a gas sealing device for a high-temperature furnace comprises an air intake pipe 1 fixed on the high-temperature furnace, an air intake channel 2 is opened inside the air intake pipe 1, an outer wall of the air intake pipe 1 is movably connected with a mounting block 3, a connecting groove 4 and a through groove 5 are respectively opened inside the mounting block 3, a return spring 6 is fixedly connected to one side of the mounting block 3, a movable block 7 is fixedly connected to one side of the return spring 6, an outer sealing gasket 8 is fixedly connected to one side of the movable block 7, an outer sealing gasket 8 is fixedly connected to one side of the outer sealing gasket 8, and an inner sealing gasket 10 is fixedly connected to one side of the connecting block 9. By setting the air intake pipe 1, the air intake channel 2, the mounting block 3 and the connecting groove 4, the function of easy installation is realized, and then it is convenient to quickly install the overall air sealing structure to the outer wall of the air intake pipe 1 of the high-temperature furnace, solving the problem of complicated installation work. At the same time, by setting the through groove 5, the return spring 6, the movable block 7, the outer sealing gasket 8, the connecting block 9 and the inner sealing gasket 10, the function of automatic deflation is realized, solving the problem of no automatic deflation, and then avoiding easy damage caused by excessive air pressure, thereby improving safety during use.

[0029] Furthermore, threads are distributed on the outer wall of the air intake pipe 1 , and the mounting block 3 is rotatably connected to the air intake pipe 1 .

[0030] Furthermore, threads are distributed on the inner wall of the connecting groove 4 , and the threads on the inner wall of the connecting groove 4 are meshed with the threads on the outer wall of the intake pipe 1 .

[0031] Furthermore, the return springs 6 are distributed at equal angles along the axial center line of the mounting block 3 , and the movable block 7 forms a telescopic structure with the mounting block 3 through the return springs 6 .

[0032] Furthermore, the diameter of the outer sealing gasket 8 is larger than the diameter of the through groove 5 , and the outer sealing gasket 8 is tightly fitted to the outer wall of the mounting block 3 .

[0033] Furthermore, the connection block 9 passes through one side of the installation block 3 through the through slot 5 , and the connection block 9 is slidably connected to the installation block 3 through the through slot 5 .

[0034] Furthermore, the diameter of the inner seal 10 is smaller than the diameter of the through groove 5 , and the diameter of the inner seal 10 is larger than the diameter of the air intake passage 2 .

[0035] Furthermore, the inner gasket 10 is tightly fitted to one side of the air intake pipe 1, and the inner gasket 10 is an elastic structure.

[0036] When in use, first install the mounting block 3 by engaging the threads of the inner wall of the connecting groove 4 with the threads of the outer wall of the intake pipe 1, and then, through the elasticity of the return spring 6, the movable block 7 drives the outer sealing gasket 8 to seal the through groove 5, and the outer sealing gasket 8 drives the inner sealing gasket 10 to seal the intake channel 2 through the outer sealing gasket 8, thereby improving the sealing effect. When the air pressure inside the high-temperature furnace is greater than the pressure applied by the return spring 6, the air pressure will squeeze the inner sealing gasket 10 to release the sealing work, so that the inner sealing gasket 10 drives the outer sealing gasket 8 to release the sealing work through the connecting block 9, and the outer sealing gasket 8 drives the return spring 6 to stretch and deform through the movable block 7. When the air pressure returns to normal, the elasticity of the return spring 6 allows the overall restoration to continue the sealing work.
