[0025] As a technical optimization solution of the present invention, by setting an expansion and telescopic component 5, the connecting groove 51 is connected with the positioning ring 52. During use, when the pressure in the reduction chamber body 2 increases, the pressure can generate pressure on the expansion ring 54 through the connecting groove 61, causing the expansion ring 54 to expand and reduce the pressure in the reduction chamber body 2.

At the same time, the heat-resistant ring 55 can provide heat-resistant protection for the inner side of the expansion ring 54 to avoid damage to the expansion ring 54 due to high heating temperature.

[0027] As a technical optimization solution of the present invention, by setting up an expansion detection component 6, when the pressure in the reduction chamber body 2 is relatively high during use, an expansion force can be generated on the insulation ring 63 through the connecting groove 61, so that the insulation ring 63 moves to push the positioning plate 64 and press the pressure sensor 65, so that the pressure sensor 65 is subjected to force to detect pressure. The insulation ring 63 can prevent the high temperature from affecting the use of the pressure sensor 65.

[0028] refer to Figure 3 A buffer block 7 is fixedly connected to the outside of the expansion ring 54. A buffer hole 8 is opened on the outside of the buffer block 7. There are several buffer holes 8, and the buffer holes 8 are arranged at equal distances.

[0029] As a technical optimization solution of the present invention, by setting a buffer block 7 and a buffer hole 8, the buffer block 7 can buffer the outer side of the expansion ring 54 during use, reducing the movement and expansion stability of the expansion ring 54 during use, and the buffer hole 8 can improve the buffering stability of the buffer block 7 during use.

[0030] refer to Figure 3 The inner side of the heat-resistant ring 55 is fixedly connected to a support block 9, the outer side of the support block 9 is fixedly connected to a positioning rod 10, and the surface of the positioning rod 10 is movably connected to a positioning column 11.

At the same time, the positioning column 11 can limit the surface movement of the positioning rod 10, so that the positioning rod 10 can stably limit the movement of the support block 9 and the expansion ring 54 during use, thereby enhancing the directional expansion stability during use.

[0033] As a technical optimization solution of the present invention, by providing a heat-resistant sealing ring 12, the heat-resistant sealing ring 12 can enhance the sealing effect between the inner side of the positioning column 11 and the outer side of the support ring 62 during use, and at the same time has a heat-resistant effect, which can effectively perform sealing.

[0034] refer to Figure 4 The outside of the reduction chamber body 2 is connected to a solenoid valve 13 , the outside of the solenoid valve 13 is connected to an expansion column 14 , and the solenoid valve 13 is electrically connected to the pressure sensor 65 through a wire.

[0035] As a technical optimization solution of the present invention, by setting the solenoid valve 13 and the expansion column 14, the solenoid valve 13 can be opened when the pressure sensor 65 detects that the pressure is relatively high, so that the solenoid valve 13 is opened and connected to the reduction chamber body 2 through the expansion column 14, which can effectively reduce the expansion buffering of the expansion ring 54 and the insulation ring 53 to the pressure.

[0036] refer to Figure 3 The ceramic fiber board 15 is fixedly connected to the inner side of the heat-resistant ring 55 , and the aerogel column 16 is fixedly connected to the interior of the positioning ring 52 .

[0037] As a technical optimization solution of the present invention, by arranging ceramic fiber boards 15 and aerogel columns 16, the ceramic fiber boards 15 can buffer and protect the inner side of the expansion ring 54. The ceramic fiber boards 15 are a fibrous lightweight refractory material with many advantages such as good elasticity, light weight, high temperature resistance, good thermal stability, and low thermal conductivity. Its elasticity is mainly reflected in its fiber structure. These fibers are interwoven with each other and can buffer external forces and adapt to shape changes to a certain extent. The aerogel column 16 is a material with a nanoporous structure. It has relatively large elasticity, extremely low density and thermal conductivity, and is a very efficient thermal insulation material. Its elasticity comes from its special three-dimensional network structure.

[0038] The working principle and use process of the present invention are as follows: when in use, the connecting groove 51 is connected with the positioning ring 52. During use, when the pressure in the reduction chamber body 2 increases, the pressure can generate pressure on the expansion ring 54 through the connecting groove 61, causing the expansion ring 54 to expand and reduce the pressure in the reduction chamber body 2. At the same time, the thermal insulation ring 53 can insulate the interior of the positioning ring 52 to prevent rapid temperature loss from affecting the normal use of the reduction chamber body 2. At the same time, the heat-resistant ring 55 can provide heat-resistant protection for the inner side of the expansion ring 54 to prevent the expansion ring 54 from being damaged by high heating temperatures. When the pressure in the reduction chamber body 2 is relatively high, an expansion force can be generated on the thermal insulation ring 53 through the connecting groove 61, causing the thermal insulation ring 53 to move and push the positioning plate 64 to press the pressure sensor 65, so that the pressure sensor 65 is subjected to force to detect pressure. The thermal insulation ring 63 can prevent high temperature from affecting the use of the pressure sensor 65, achieving the effect of directional expansion and enhancing the safety of the reduction chamber.

[0039] To sum up: this kind of directional telescopic expansion thermal decomposition reduction chamber structure, by setting the expansion and telescopic component 5 and cooperating with the expansion detection component 6 to stably and conveniently carry out directional buffering expansion in the reduction chamber body 2, solves the problem that the existing thermal decomposition reduction chamber cannot directional telescopic expansion. This heat-conducting thermal decomposition reduction chamber expands and contracts due to heat and cold during operation. The materials in different parts may produce excessive stress due to mutual squeezing, thereby causing damage, reducing the safety of the reduction chamber.
