[0006] Preferably, the push ring on the upper side and the lower side can be clamped together, and the flange away from the one end of the inner sealing ring is rotationally connected with the connecting ring.

[0007] Preferably, the connecting ring is screw-connected with the fixed ring on the inner side of the one end away from the inner sealing ring, and the end of the fixed ring is fixed with the push ring.

[0008] Preferably, the push ring is a hollow circular truncated cone structure, and the inner wall of the push ring is attached to the outer side of the flange.

[0009] Preferably, the moving distance of the push ring is equal to the distance from the push ring to the end of the flange, and the moving distance of the push ring is less than the thread width of the fixed ring and the connecting ring.

[0010] Compared with the prior art, the utility model has the beneficial effects that:

[0011] The push ring is located outside the flange, the inner wall of the push ring is in contact with the end of the flange, the outer sealing ring is installed at the end of the push ring, the upper and lower outer sealing rings are extruded to realize sealing, the upper and lower inner sealing rings are extruded to realize sealing, the steel wire mesh framework composite pipe is realized double sealing, the sealing effect is improved, the fixed ring rotates to make the two flanges close to each other, due to the structure of the fixed ring, the fixed ring is subjected to the same force around, and then the outer side of the inner sealing ring is subjected to the same force, and the sealing effect is improved.
