Description

Technical Field

[0001] This utility model relates to the field of HVAC pipe connection, and more particularly to a pipe connection device for HVAC equipment. Background Technology

[0002] HVAC duct connection technology is a crucial element in the building industry, as its quality directly impacts the operational efficiency and safety of the entire HVAC system. With continuous advancements in building technology and the growing acceptance of energy conservation and environmental protection concepts, HVAC duct connection technology is constantly innovating and developing.

[0003] In terms of connection technology, while traditional fire welding offers advantages such as low heating temperatures and smooth, flat joints, it also suffers from problems like weld blockages and leaks, and significant safety hazards. To address these issues, flameless connection technology has emerged. This technology utilizes physical means such as connecting rings to connect pipes, eliminating the need for open flames and greatly improving safety and ease of operation. Furthermore, flameless connection technology effectively avoids problems such as weld slag blockage and internal refrigerant system hazards, providing strong support for the stable operation of HVAC systems. Besides material and technology selection, the installation and commissioning of HVAC pipe connection equipment are also crucial for ensuring the normal operation of the system. During installation, it is essential to strictly adhere to relevant specifications and standards to ensure the strength and sealing of pipe connections. Simultaneously, it is necessary to commission and monitor the piping system to ensure that all parameters meet design requirements. Utility Model Content
