Description

Technical Field

[0001] This utility model relates to the field of plumbing technology, and in particular to a plumbing pipe connection device for heating and ventilation equipment. Background Technology

[0002] Water heating is an important heating method in cold regions or places. HVAC is a general term for heating and ventilation. All equipment related to heating and ventilation, such as air conditioners, ventilation ducts, control equipment, boilers, pipes, radiators and electric heating equipment that use air as a heat medium, are collectively called HVAC equipment. The recently popular HVAC air conditioning is a new type of HVAC equipment, which is actually a small-scale central air conditioning system.

[0003] Existing plumbing pipe connections typically use upper and lower retaining rings, secured by bolts and nuts. In actual use, when the plumbing pipe connection is suspended, the high airflow rate inside the pipe can cause it to vibrate. Over time, this can lead to loosening of the bolts and nuts, which in turn causes the upper and lower retaining rings to loosen, resulting in air leakage and wasted heating energy.
