[0026] During specific use, the staff aligns the card block 10 fixedly connected to the explosion-proof plate 9 with the card slot 7 opened on the connecting pipe 2 and snaps it in, and passes an inner hexagon bolt through the hole opened on the card block 10 and threadedly connects it with the threaded hole on the connecting pipe 2 to fix the explosion-proof plate 9 on the connecting pipe 2. Then, the pressure relief pipe 1 is installed on the connecting pipe 2, so that the convex block on the gasket 4 fixedly connected to the pressure relief pipe 1 snaps into the card slot 7 opened on the connecting pipe 2, and the bolt passes through the flange plates on the connecting pipe 2 and the pressure relief pipe 1 and is threadedly connected through a nut to fix the connecting pipe 2 and the pressure relief pipe 1 together.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, a spring 14 is provided to ensure the safety of the pressure vessel main body 8. The other end of the spring 14 is fixedly connected to the top plate 15. A connection hole 16 and a ventilation groove 18 are formed in the top plate 15. The connection hole 16 is in a circular groove structure. When the pressure relief pipe 1 is installed on the connection pipe 2, the spring 14 is in a tense state, so that the top plate 15 contacts the explosion-proof plate 9, and the top plate 15 has a certain thrust on the explosion-proof plate 9, providing a certain support for the explosion-proof plate 9 and improving the use effect of the explosion-proof plate 9. The clamping groove 7 is in a square groove structure. A clamping block 10 is clamped in the clamping groove 7. The clamping block 10 can slide along the clamping groove 7. The clamping block 10 is fixedly connected to the explosion-proof plate 9. If the pressure in the pressure vessel main body 8 is too high, causing the explosion-proof plate 9 to deform or the explosion-proof plate 9 to separate from the connection pipe 2, the explosion-proof plate 9 and the clamping block 10 slide along the clamping groove 7 to push the top plate 15 to slide along the clamping groove 7. The limiting rod 13 is in a cylindrical structure. One end of the limiting rod 13 is clamped in the limiting hole 17 formed above the top plate 15. The limiting rod 13 can slide along the limiting hole 17. The limiting hole 17 is in a circular groove structure, enabling the top plate 15 to slide along the limiting rod 13 fixedly connected to the fixing plate 5. The limiting rod 13 slides with the limiting hole 17 formed in the top plate 15, so that the steel needle 11 fixedly connected to the fixing plate 5 is inserted into and penetrates through the connection hole 16 formed in the top plate 15. The steel needle 11 can pierce the explosion-proof plate 9, causing the explosion-proof plate 9 to break, so that the gas in the pressure vessel main body 8 can flow out. The gas in the pressure vessel main body 8 flows into the pressure relief pipe 1 through the ventilation groove 18 formed in the top plate 15 and is depressurized through the pressure relief pipe 1, avoiding the explosion of the pressure vessel main body 8 due to excessive pressure and improving the safety of the pressure vessel main body 8.

[0029] Embodiment Three

[0030] On the basis of the second embodiment, a top plate 15 is provided for the convenience of the staff. A number of indicating rods 12 are fixedly connected to the top plate 15. The indicating rods 12 are cylindrical structures. One end of the indicating rods 12 can be just seen by the staff through the explosion-proof observation window 3 installed on the pressure relief pipe 1. The fixing plate 5 is fixedly connected to the pressure relief pipe 1. A steel needle 11, a limiting rod 13 and a spring 14 are fixedly connected to the pressure relief pipe 1. An explosion-proof observation window 3 is installed on the pressure relief pipe 1. If the explosion-proof plate 9 is deformed, the deformed part of the explosion-proof plate 9 can push the top plate 15 to move along the limiting rod 13. The staff can then observe through the explosion-proof observation window 3 that the position of the indicating rod 12 fixedly connected to the top plate 15 has changed, which is convenient for the staff to use. The staff can clearly understand the state of the explosion-proof plate 9. The sealing gasket 4 is fixedly connected to the pressure relief pipe 1. The convex block fixedly connected to the sealing gasket 4 can be inserted into the clamping groove 7 opened on the connecting pipe 2. The connecting pipe 2 is fixedly connected to the pressure vessel body 8. A valve 6 is installed on the connecting pipe 2. The staff closes the valve 6, unscrews and removes the bolts and nuts at the upper end of the flange on the pressure relief pipe 1 and the connecting pipe 2, and removes the pressure relief pipe 1. The staff then unscrews and removes the hexagon socket head bolt on the clamping block 10 fixedly connected to the side of the explosion-proof plate 9, and can remove the damaged explosion-proof plate 9 and replace it with a new explosion-proof plate 9, ensuring the effectiveness of the protection component, improving the reliability of the device, being convenient for the staff to use, facilitating the later maintenance by the staff, and having high practicability.

[0031] During actual use, when the explosion-proof plate 9 is deformed, its deformed part can push the top plate 15 to move along the limiting rod 13. The staff can then observe through the explosion-proof observation window 3 that the position of the indicating rod 12 fixedly connected to the top plate 15 has changed, and can clearly understand the state of the explosion-proof plate 9. The pressure relief pipe 1 is removed from the connecting pipe 2, and then the hexagon socket head bolt on the clamping block 10 fixedly connected to the side of the explosion-proof plate 9 is unscrewed and removed, and the damaged explosion-proof plate 9 can be removed and replaced with a new explosion-proof plate 9, ensuring the effectiveness of the protection component, improving the reliability of the device, and facilitating the later maintenance by the staff. When the pressure in the pressure vessel body 8 is too high, the explosion-proof plate 9 is separated from the connecting pipe 2. The explosion-proof plate 9 and the clamping block 10 slide along the clamping groove 7 under the push of the pressure and push the top plate 15 to slide along the clamping groove 7, so that the steel needle 11 fixedly connected to the fixing plate 5 is inserted into and penetrates the connecting hole 16 to pierce the explosion-proof plate 9, enabling the gas in the pressure vessel body 8 to flow out. The pressure vessel body 8 is depressurized through the pressure relief pipe 1, preventing the pressure vessel body 8 from exploding due to excessive pressure, enhancing the safety of the pressure vessel body 8, improving the reliability of the device, and having high practicability.
