[0002] The thickness and specification of the heating and ventilation pipeline need to be adjusted according to the construction requirements.

However, the existing connection simply uses a single sealing ring connection, and the sealing member structure is single. The sealing ring may be damaged after long-term use, or it may naturally age, or it may be affected by the use conditions to accelerate aging, hardening or deformation, which reduces the sealing performance of the sealing ring. The internal hydraulic pressure or air pressure of the pipeline may be discharged through the sealing ring connection, causing leakage. This may cause the leakage of liquid or gas medium, or the entry of cold air under no pressure or negative pressure conditions, which may affect the heating effect of the heating and ventilation and the use performance of the heating and ventilation pipeline.

DETAILED DESCRIPTION
[0019] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.
[0020] like Figures 1-4 As shown, a heating pipe splicing structure includes a connector 1. Pipes 2 are detachably installed on both sides of the connector 1. A first sealing sleeve 9 is detachably installed on one pipe 2 near the connector 1, and the first sealing sleeve 9 further seals the pipe 2. A second sealing sleeve 10 is connected to the other pipe 2 near the connector 1, and the second sealing sleeve 10 further seals the pipe 2. A threaded rod 11 is connected to one end of the first sealing sleeve 9, and an internal thread 12 is connected to the inner wall of the second sealing sleeve 10, so that the first sealing sleeve 9 and the second sealing sleeve 10 form a threaded connection.
[0021] In this embodiment, a first sealing seat 4 is fitted on one side of the connection between the connector 1 and the pipe 2, and a second sealing seat 5 is fitted on the other side of the connection between the connector 1 and the pipe 2. The sealing ring 3 is fixedly installed at the connection between the pipe 2 and the connector 1. The sealing ring 3 is detachably installed at the connection between the connector 1 and the pipe 2. The sealing ring 3 prevents liquid or gas medium from overflowing from the connection between the pipe 2 and the connector 1, and the sealing ring 3 is located inside the first sealing seat 4 and the second sealing seat 5.
[0022] Furthermore, both the upper and lower ends of the first sealing seat 4 and the second sealing seat 5 are fixedly connected to connecting blocks 6. Threaded pins 7 are threadedly connected inside the connecting blocks 6, and locking nuts 8 are threadedly connected to one end of the threaded pins 7. The first sealing seat 4 and the second sealing seat 5 are fixedly connected through the threaded pins 7 and locking nuts 8. A temperature sensor 13 is connected to the upper end of the inner wall of the first sealing sleeve 9, and a humidity sensor 14 is connected to the upper end of the inner wall of the second sealing sleeve 10. An alarm 15 is connected to the outside of the first sealing sleeve 9. Both the temperature sensor 13 and the humidity sensor 14 are electrically connected to the alarm 15. The temperature sensor 13 senses the temperature of the pipe 2, and the humidity sensor 14 senses the humidity inside the first sealing sleeve 9 and the second sealing sleeve 10. The alarm 15 alerts the staff that a leak has occurred at the connection between the pipe 2 and the connector 1.
[0023] Furthermore, both the first sealing sleeve 9 and the second sealing sleeve 10 are hollow structures, and the threaded rod 11 matches the internal thread 12, so that the first sealing sleeve 9 and the second sealing sleeve 10 can be sleeved on the outside of the connector 1; the first sealing seat 4 and the second sealing seat 5 are semicircles with the same diameter, and the inner diameter of the first sealing seat 4 and the second sealing seat 5 matches the outer diameter of the sealing ring 3.
[0024] The working principle and usage process of this utility model are as follows: The operator first puts the sealing ring 3 on the connection between the connector 1 and the pipe 2, then puts the first sealing seat 4 and the second sealing seat 5 on the outer surface of the sealing ring 3, and makes the connecting block 6 on the first sealing seat 4 coincide with the connecting block 6 on the second sealing seat 5. The first sealing seat 4 and the second sealing seat 5 are fixedly connected by the threaded pin 7 and the locking nut 8, so that the sealing ring 3 is fixedly fitted on the connection between the connector 1 and the pipe 2; then rotate the first sealing sleeve 9 and rotate the threaded rod 11 into the internal thread 12, so that the first sealing sleeve 9 and the second sealing sleeve 10 are fixedly connected. When the sealing ring 3 is damaged after prolonged use, the water or air pressure inside the pipe 2 will discharge the liquid or gas medium through the sealing ring 3. Sealing gaskets are installed at the outer ends of the first sealing sleeve 9 and the second sealing sleeve 10, that is, at the connection between the first sealing sleeve 9 and the pipe 2 and the connection between the second sealing sleeve 10 and the pipe. The first sealing sleeve 9 and the second sealing sleeve 10 play a secondary sealing role, preventing the liquid or gas medium from flowing out and the external cold air from entering the pipe 2, thereby avoiding actual leakage at the sealing ring 3 and improving the sealing performance of the pipe 2 splice. In addition, the splice structure also needs to be equipped with a corresponding waterproof power supply to provide the necessary power for the temperature sensor 13, humidity sensor 14 and even the alarm connected to the sensor.
[0025] Finally, it should be noted that the above descriptions are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Those skilled in the art can modify or make equivalent substitutions to the technical solutions described in the foregoing embodiments. Any modifications or equivalent substitutions made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
