Description

TECHNICAL FIELD

[0001] The utility model relates to pipeline connection technical field, especially a heating ventilation pipeline connection structure. BACKGROUND

[0002] Heating ventilation pipeline, also known as heating ventilation equipment pipeline, is mainly used in ventilation, air conditioning, heating and the like, is the pipeline system connecting heating ventilation equipment, and the heating ventilation pipeline is an indispensable component in building and plays an important role in guaranteeing indoor air quality, adjusting temperature and humidity and keeping air circulation.

[0003] In the prior art, in order to improve the sealing performance of the heating ventilation pipeline, a sealing air bag and quicklime are combined, the air bag is directly wrapped on the outer wall of the pipeline, water and quicklime are reacted to generate gas to fill the entire sealing air bag, the sealing air bag is tightly wrapped between the gaps of the pipeline in the inflated state, thereby realizing the connection and sealing of the pipeline, and when replacement is needed, the sealing air bag is only needed to be punctured to facilitate replacement.

[0004] However, in the above scheme, when the connected pipeline leaks after installation, the sealing air bag needs to be punctured to repair the connection of the pipeline, and the sealing air bag and quicklime are used again after repair, which causes material waste, increases repair cost, and on the other hand, after the sealing air bag is punctured, the pressure operation increases the replacement risk of personnel, and the lime water in the sealing air bag flows out from the connection of the pipeline, causing the lime water stored in the air bag to leak to the pipeline interface, which is easy to cause alkaline pollution.

[0014] Further, the lower side of the first connecting ring and the second connecting ring is provided with a recovery assembly, and the installation groove is provided with a liquid leakage hole communicated to the recovery assembly, so that the liquid in the installation groove can flow to the recovery assembly.

[0017] Further, the upper side of the first connecting ring and / or the second connecting ring is provided with a light-heat assembly, and the light-heat assembly is used to transfer the energy of light to the thermal expansion sealing ring and the liquid suction member.

[0018] Further, the light-heat assembly comprises a mirror rotatably arranged above the first connecting ring and / or the second connecting ring.

[0019] Further, a frame is mounted on the periphery of the reflector, the frame rotates above the first connecting ring and / or the second connecting ring, and an adjusting head is arranged at the rotating position of the frame.

[0020] Further, the first connecting ring and the second connecting ring are respectively connected with a first sleeve and a second sleeve at the ends away from each other.

[0021] The above technical scheme has the following advantages:

[0022] The heat expansion sealing ring is connected to the end of the pipeline, and the expanded heat expansion sealing ring can further improve the tightness with the pipeline, thereby further improving the sealing effect of the sealing ring, avoiding liquid leakage, and quickly completing the connection of the pipeline.
