Heating and ventilating construction pipeline connecting structure

Abstract

The invention discloses a heating and ventilating construction pipeline connecting structure. The heating and ventilating construction pipeline connecting structure comprises a first connecting ring and a second connecting ring which are fixedly installed on a main pipeline, the first connecting ring is provided with a first installation groove, a second installation groove and a sliding groove, aclamping mechanism is arranged between the side wall of the second connecting ring and the first installation groove, a blocking mechanism is arranged between the second installation groove and the sliding groove, the blocking mechanism extends into the clamping mechanism and abuts against the inner side wall of the clamping mechanism, a sealing cavity is formed in the second connecting ring, anda sealing mechanism is arranged between the sealing cavity in the second connecting ring and the side wall of the second connecting ring. The heating and ventilating construction pipeline connectingstructure has reasonable structural design, can stably seal the inner space of a pipeline, prevents the joint of a connecting pipeline inside the pipeline from being oxidized and corroded by outside humid air, can timely discharge the leaked water when the connecting pipeline leaks water, and ensures the dryness inside the pipeline.

Description

technical field [0001] The invention relates to the technical field of heating and ventilation construction pipelines, in particular to a connection structure for heating and ventilation construction pipelines. Background technique [0002] HVAC is an integral part of the building. In the subject classification, it is called heating, gas, ventilation and air conditioning engineering, including: heating, ventilation, and air conditioning. It is also an indispensable part of the future family from a functional point of view. , The heating and ventilation pipes are connected to various pipes needed for family life, such as heating pipes, water inlet pipes, drain pipes, gas pipes, etc. [0003] In the prior art, when the existing HVAC construction pipelines are connected, they are generally connected by welding. There is a problem of missing welding in the welded connection, and the sealing performance in the pipeline is poor, which will cause the joints of the connecting pipeli...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing heating and ventilation construction pipelines in the prior art are generally connected by welding. The joints of the connecting pipes are oxidized and corroded, which affects the normal use of the connecting pipes, and when water leaks at the connecting pipes, the leaked water will gather in the pipes and is not easy to discharge, and a HVAC construction pipe connection is proposed structure, which can stably seal the internal space of the pipeline, prevent the connection of the connecting pipeline inside the pipeline from being oxidized and corroded by the external humid air, and when the connecting pipeline leaks, the leaked water can be discharged in time to ensure the internal safety of the pipeline. dry
