[0001] The utility model relates to the technical field of HVAC exhaust, in particular to a building HVAC exhaust structure. Background Art

[0002] HVAC stands for heating, gas supply, ventilation and air conditioning engineering, including: heating, ventilation, and air conditioning. Functionally, it is a part of the construction industry.

[0003] When HVAC equipment is in use, it will generate excess gas, causing the internal air pressure to rise. It is necessary to discharge the gas in time to ensure that the internal pressure of the HVAC equipment is within an appropriate range. However, the existing HVAC equipment requires manual exhaust, which is inconvenient and cannot exhaust in time to adjust the internal air pressure. Content of the Utility Model

[0004] The utility model provides a building HVAC exhaust structure to solve the problems in the prior art.

[0036] The reset valve stem 210 of the exhaust valve part 200 is installed on the orifice plate 102 inside the exhaust pipe 100, and the blocking valve piece 220 at the lower end of the reset valve stem 210 blocks the lower end of the exhaust pipe 100. At the same time, the electric telescopic rod 310 installed at the upper end of the exhaust pipe 100 contacts the upper end of the reset valve stem 210 through the pressure column 320. Moreover, a wireless pressure sensor 230 is installed at the lower end of the blocking valve piece 220. During use, the wireless pressure sensor 230 transmits the internal air pressure of the heating and ventilation equipment to the control terminal computer for monitoring. When the air pressure reaches the set value, the control terminal computer controls the electric telescopic rod 310 to drive the pressure column 320 to press down the reset valve stem 210. The blocking valve piece 220 moves downward to open the lower end of the exhaust pipe 100, and the excess gas is discharged through the exhaust port 101 at the upper end of the exhaust pipe 100. It is more convenient without manual exhaust and can adjust the internal air pressure by exhausting in a timely manner.

[0037] As a further preference of the above embodiment, a first connecting ear 111 is provided in the middle of the outer wall of the exhaust pipe 100, which facilitates connection with the heating and ventilation equipment through the first connecting ear 111.
