Description

Technical Field

[0001] This utility model relates to the field of quick-connect pipe technology, and in particular to a self-compensating direct high-efficiency quick-connect pipe. Background Technology

[0002] Pipeline compensators, also known as expansion joints or expansion valves, are used to compensate for the thermal expansion and contraction of pipelines caused by temperature changes. If the pipeline cannot expand or contract freely when the temperature changes, thermal stress will be generated in the pipeline. This stress must be considered in pipeline design, otherwise it may lead to pipeline rupture and affect normal production. As an important component of pipeline engineering, compensators play an important role in ensuring the long-term normal operation of pipelines.

[0003] In existing self-compensating pipeline connections, the pipeline compensator is connected to the pipeline body, and then the pipeline is rotated or connected by a connector to achieve a threaded connection and seal. However, this method is cumbersome and inefficient, especially for large pipelines. The transportation, connection, and rotation of the pipeline are very complicated, the operation is difficult, and the sealing is even more difficult, making it impossible to achieve efficient and quick connection and sealing. Utility Model Content

[0004] This utility model provides a self-compensating direct high-efficiency quick-connect pipe. The pipe body and the quick-connect pipe body are in a transition fit, allowing the pipe body to be directly sleeved inside the quick-connect pipe body with the end located in the snap-fit ​​cavity. The connection is convenient and quick. After connection, the inflatable sealing ring is inflated to create a spiral seal between the pipe body and the quick-connect pipe body. This not only ensures a stable connection and better sealing, but also allows for direct sleeve connection, making operation convenient and eliminating the need for rotation or other operations, thus greatly improving the efficiency of pipe connection.

[0005] To achieve the above objectives, a self-compensating direct-connect high-efficiency quick-connect pipe is provided, comprising: an compensator body, a quick-connect assembly fixedly connected to the top of the compensator body, the quick-connect assembly including a quick-connect pipe body, an inner ring, a snap-fit ​​cavity, a gas pipe groove, a quick-connect flange, bolt holes, an inflation sealing ring, a pressure gauge, a gas nozzle, and a pressure valve. The inner ring is fixedly connected inside the quick-connect pipe body, forming a snap-fit ​​cavity with the inner circumferential surface of the quick-connect pipe body. A gas pipe groove is provided on the inner circumferential surface of the quick-connect pipe body, the gas pipe groove being spiral-shaped. A quick-connect flange is fixedly connected to the circumferential surface of the quick-connect pipe body, and bolt holes are provided on the quick-connect flange. An inflation sealing ring is snapped into the inside of the gas pipe groove, the inflation sealing ring being spiral-shaped. A pressure gauge is fixedly connected to the inflation sealing ring, and a gas nozzle is fixedly connected to the end of the pressure gauge away from the inflation sealing ring. A pressure valve is fixedly connected to the circumferential surface of the gas nozzle.

[0006] According to the self-compensating direct high-efficiency quick-connect pipe, there are two quick-connect components, which are symmetrically distributed on the upper and lower sides of the compensator body. The pipe body is snapped into the inside of the snap-fit ​​cavity. The pipe body and the quick-connect pipe body are in transition fit. A pipe flange is fixedly connected to the circumferential surface of the pipe body.

[0007] According to the self-compensating direct high-efficiency quick-connect pipe, the number of bolt holes is set to multiple and evenly distributed on the quick-connect flange.

[0008] According to the self-compensating direct high-efficiency quick-connect pipe, the pipe flange and the quick-connect flange are fixedly connected by bolts.

[0009] According to the self-compensating direct high-efficiency quick-connect pipe, the inflatable sealing ring is made of wear-resistant rubber.

[0010] According to the self-compensating direct high-efficiency quick-connect pipe, the pressure gauge, air nozzle, and pressure valve are all located on the outside of the quick-connect pipe body.

[0011] The beneficial effects of this utility model are as follows: By setting up a quick-connect pipe body, inner ring, snap-fit ​​cavity, air pipe groove, quick-connect flange, bolt hole, inflation sealing ring, air pressure gauge, air nozzle, air pressure valve, pipe body and pipe flange, the pipe body and quick-connect pipe body are in a transition fit, and the pipe body can be directly sleeved inside the quick-connect pipe body with the end located in the snap-fit ​​cavity, making the connection convenient and quick.
