[0030] Embodiment 2

[0031] On the basis of the first embodiment, a constraint component is set to constrain the connection state of the mounting disk 2 and the mounting sealing plate 3, and the constraint component includes an annular function box 7 and a plurality of constraint rods 10. The annular function box 7 is sleeved with the mounting disk 2 and the mounting sealing plate 3, and the plurality of constraint rods 10 are respectively and horizontally symmetrically plugged into the inner circumference of the annular function box 7, and the plurality of constraint rods 10 are respectively in contact with one side of the mounting disk 2 and the mounting sealing plate 3. A guide plate is provided at the upper end of the annular function box 7, and the guide plate is overlapped with the upper end of the mounting sealing plate 3, and the upper end of the assembly bolt 4 is abutted against the lower end of the guide plate. An annular air groove 8 is opened in the annular function box 7, and the annular function box A plurality of piston grooves 9 are symmetrically provided at the upper and lower ends of one side of the annular air groove 8 in the inner part 7, and the two sides of the piston groove 9 are respectively connected to the annular air groove 8 and the air groove and the rod groove are provided on the inner circumference side of the annular functional box 7, and the constraint rod 10 is horizontally placed in the piston groove 9 and one side is movable through the rod groove, and the constraint rod 10 is placed in the piston groove 9. A constraint piston 11 is provided on one side of the constraint rod 10, and a reset spring 12 is sleeved on one side of the constraint piston 11 of the constraint rod 10 located in the rod groove, and the guide plate abuts against the upper end of the assembly bolt 4 to prevent the assembly bolt 4 from moving upward, and a rubber sealing gasket can be provided at the position where the guide plate abuts against the upper end of the mounting sealing plate 3;

[0032] A plurality of restraining rods 10 on the upper and lower sides of the annular functional box 7 are respectively abutted against the upper and lower ends of the mounting sealing plate 3 and the mounting disk 2, and the side surfaces of the restraining rods 10 close to the mounting sealing plate 3 and the mounting disk 2 are all inclined surfaces. When the restraining rods 10 extend out of the piston groove 9 and abut against the side edges of the mounting disk 2 and the mounting sealing plate 3, the mounting disk 2 and the mounting sealing plate 3 can be effectively prevented from moving up and down, thereby improving the stability of the pressed seal between the two.

[0033] The design of the inclined surface makes it convenient for the restraining rod 10 to press against the mounting disk 2 and the mounting sealing plate 3 when it extends out of the annular functional box 7, thereby preventing the restraining rod 10 from abutting and getting stuck against the outer peripheral sides of the mounting disk 2 and the mounting sealing plate 3. In addition, a matching key groove and key strip can be provided on one side of the restraining rod 10 that passes through the rod groove, so that the inclined surface of the restraining rod 10 is always facing the mounting disk 2 and the mounting sealing plate 3.

[0034] Embodiment 3

[0035] On the basis of the second embodiment, a reinforced sealing component is provided to perform additional sealing on the joint between the mounting disk 2 and the mounting sealing plate 3.

An annular groove is provided on one side of the annular functional box 7 close to the mounting disk 2 and the mounting sealing plate 3. The expansion sealing ring 14 is horizontally inserted into the annular groove. The expansion sealing ring 14 contacts the joint between the mounting disk 2 and the mounting sealing plate 3 on the outer peripheral side. A connecting groove 13 is vertically provided between the upper and lower piston grooves 9 in the annular functional box 7. The expansion sealing ring A connecting pipe is sealed and inserted between 14 and the connecting groove 13, and when the restraining rod 10 extends out of the annular functional box 7 to the maximum extent, the connecting groove 13 is connected with the annular gas groove 8 through the piston groove 9. When the two first sealing rings 5 ​​leak, under the action of the second sealing ring 6, the volatile gas cannot be discharged through the connection position of the assembly bolt 4, and then the expansion sealing ring 14 seals the joint of the mounting plate 2 and the mounting sealing plate 3, thereby improving the sealing effect of preventing the volatile gas from leaking, and as the air pressure increases, the expansion sealing ring 14 continues to expand, which can improve the sealing quality;

[0036] In this embodiment, when high-pressure gas is injected into the annular air groove 8 through the air compressor and the self-sealing single-line valve, the high-pressure gas simultaneously pushes a plurality of restraining pistons 11 and restraining rods 10 to move toward the positions of the mounting disk 2 and the mounting sealing plate 3, and under the action of the inclined surface, the mounting disk 2 and the mounting sealing plate 3 are further pressed and positioned. When the restraining rod 10 is extended to the maximum position, the connecting groove 13 is connected with the annular air groove 8 through the piston groove 9. At this time, the high-pressure gas in the annular air groove 8 enters the expansion sealing ring 14 through the connecting groove 13, and the expansion sealing ring 14 expands to strengthen the sealing of the joint between the mounting disk 2 and the mounting sealing plate 3.
