Technical Field

[0001] The utility model relates to the field of HVAC pipeline connection devices, in particular to a HVAC pipeline connection device. Background Art

[0002] HVAC pipe connection devices are key components used to connect pipes, fittings and equipment in HVAC systems. HVAC systems include heating, ventilation and air-conditioning systems. The pipes in these systems need to be connected through connection devices to ensure sealing, stability and good fluid transmission. The connection method is commonly used to connect metal pipes and fittings. A groove is formed at the end of the pipe and then welded at the groove. A method of cutting an internal thread at the end of the pipe and then connecting it with a threaded fitting is usually used in piping systems that require frequent disassembly and installation.

[0003] In the specific connection of HVAC pipes, there are many connection methods, but most of the connection devices are cumbersome to install, which will increase the installation time, and the usual connection methods can only connect the HVAC pipes, which has limited effect.
