[0024] like Figure 1-Figure 7 As shown, a vibration-resistant pressure vessel flange provided in this embodiment includes a flange 1 and a flange 2, one side of the flange 2 is welded to the inlet of the pressure vessel, and the flange 2 is fixedly connected to the pressure vessel, a groove 3 is provided on one side of the flange 1, and a groove 4 is provided on the side of the flange 2 close to the groove 3, a plurality of ratchets 5 are fixedly connected to the upper top surface of the groove 3, a ratchets 6 are fixedly connected to the lower bottom surface of the groove 4, a sealing ring 7 is provided inside the groove 4, and when the sealing ring 7 is located inside the groove 4, the sealing ring 7 can be limited by the plurality of ratchets 6 to prevent the sealing ring 7 from moving, and when the flange 1 is moved to make the upper side of the sealing ring 7 slide inside the groove 3, the plurality of ratchets 5 and the sealing ring 7 conflict with each other, and the flange 1 cannot rotate through the tight conflict between the ratchets 5 and the ratchets 6 and the sealing ring 7;

[0025] Further, such as Figure 1-Figure 7 As shown, the upper and lower sides of the sealing ring 7 are provided with limit grooves 12, the limit grooves 12 correspond to the ratchet 1 5, and the limit grooves 12 correspond to the ratchet 2 6. When the sealing ring 7 is located inside the groove 1 3 and the groove 2 4, the sealing ring 7 is rotated so that the ratchet 1 5 and the ratchet 2 6 are both located inside the limit grooves 12, which limits the rotation of the sealing ring 7 and prevents the sealing ring 7 from rotating during vibration.

[0026] Among them, Figure 1-Figure 7As shown, a rubber plug 8 is fixedly connected to the lower bottom surface of flange 1, a cavity 9 is opened inside the rubber plug 8, and a plurality of limit blocks 10 are fixedly connected inside the rubber plug 8, one end of the plurality of limit blocks 10 is located in the cavity 9, and the other end of the plurality of limit blocks 10 extends to the outer wall of the rubber plug 8. When flange 1 and flange 2 collide with each other, the rubber plug 8 will slide to the inside of the inlet of the pressure vessel, and then push one end of the plurality of limit blocks 10, so that the other end of the plurality of limit blocks 10 extends from the outer wall of the rubber plug 8. After the plurality of limit blocks 10 are in close contact with the pressure vessel, a limit is formed, which can prevent vibration during vibration.

[0027] Among them, Figure 1-Figure 7 As shown, a turntable 13 is rotatably connected in the cavity 9, and a plurality of abutment disks 14 are fixedly connected to the outer wall of the turntable 13. The plurality of abutment disks 14 correspond to the plurality of limit blocks 10 one by one, and the outer wall of the abutment disk 14 abuts against the outer wall of one end of the limit block 10. The turntable 13 is rotated to drive the plurality of abutment disks 14 to move, and the other end of the limit block 10 is pushed to move under the action of the plurality of abutment disks 14.

[0028] Further, such as Figure 1-Figure 7 As shown, the plurality of abutment disks 14 are in the shape of semicircular disks, and the sides of the plurality of limit blocks 10 close to the abutment disks 14 are curved surfaces, so as to reduce the friction between the abutment disks 14 and the limit blocks 10 when the abutment disks 14 rotate with the turntable 13.

[0029] Further, such as Figure 1-Figure 7 As shown, a screw rod 15 is fixedly connected to the upper surface of the turntable 13, and the screw rod 15 is threadedly connected to the flange 1, and the other end of the screw rod 15 extends to the other side of the flange 1, so that the turntable 13 can be driven to rotate by the screw rod 15.

One end of the connecting column 16 extends into the sliding groove 17, and the connecting column 16 is slidably connected to the sliding groove 17. When the contact plate 14 breaks the mutual interference with the contact block, under the action of the connecting column 16, the limit block 10 can be pulled to move into the cavity 9.

[0032] like Figure 1-Figure 7As shown, the principle of a vibration-resistant pressure vessel flange provided in this embodiment is as follows: by welding flange 2 to the pressure vessel, moving flange 1, driving the rubber plug 8 to move to the inside of the pressure vessel inlet, so that flange 1 and flange 2 are in contact with the sealing ring 7 at the same time, rotating the sealing ring 7 so that multiple ratchet teeth 1 5 and multiple ratchet teeth 2 6 are located in the limiting groove 12, and then using bolts to pass through the connecting hole 11 to fix flange 1 and flange 2 2, rotating the screw rod 15 to drive the turntable 13, and the turntable 13 drives the contact plate 14 to move, and the contact plate 14 moves to drive the connecting column 16 to slide in the slide groove 17, and at the same time, the contact plate 14 contacts the limit block 10 from the inside of the cavity 9 to the outside, and the limit is formed by the limit block 10.

[0033] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
