Description

Technical Field

[0001] The utility model relates to the technical field of pipe connection, in particular to a pipe compression connection sealing structure. Background Art

[0002] The pipe compression connection sealing structure seals and connects two pipes to achieve conductivity between the two pipes, which plays an important role in the transportation industry. In the current connection structure, when liquid or gas enters the gap between the two pipes, it usually generates a thrust on the sealing ring, which increases the pressure of the sealing ring and causes the sealing ring to fail prematurely. The sealing ring needs to be maintained and replaced in the short term, and the later maintenance cost is very high.

[0003] In the application with patent number CN220706659U, a pet attractant storage container is disclosed, including a first tube, a first sealing ring, a second tube and a second sealing ring, one end of the second tube is inserted in the second tube, and the outer wall of the second tube abuts against the first sealing ring; the second sealing ring is provided with a slot, the tube wall of one end of the second tube is inserted in the slot, and the second sealing ring abuts against the inner wall of the first tube, and the double sealing ring is used to improve the sealing effect and stability and reduce the subsequent maintenance cost.

[0004] However, due to the setting of the first sealing ring and the second sealing ring, when the two pipes start to transport liquid or gas, the pipes will be subjected to a certain thrust, which may easily cause the pipes to shake against each other and produce displacement. The friction of the pipe connection is low and the stability is poor. The pipes are easily separated under the action of external forces. At the same time, since the sealing ring is set on the inner wall, the pipe can easily drive the sealing ring to move, resulting in poor sealing effect of the sealing ring and easy formation of gaps.

[0011] Preferably, the sealing gasket A and the sealing gasket B are made of rubber material, which can improve the sealing performance of the sealing gasket A and the sealing gasket B.

[0012] Preferably, the distance from the limiting ring to the right plane of the pipe A is 5 cm, and the length of the sealing sleeve is 5 cm, which can ensure that the sealing sleeve completely enters the pipe A, thereby improving the fit and stability of the connection between the two.

[0013] Preferably, an elastic rubber layer is mounted on the inner wall of the pipe A, so as to improve the sealing performance between the pipe A and the sealing sleeve.
