The air-leakage-prevention adjusting valve comprises a square pipe body, flange openings are formed in the two ends of the pipe body, connecting holes are formed in the four corners of the flange openings, a rotating plate is mounted in the pipe body, the pipe body is formed by three-time right-angle bending and surrounding of a galvanized sheet, right-angle bending connecting plates are arranged at the two ends of the galvanized sheet, and the two connecting plates are in riveted or welded connection with the side wall of the corresponding pipe body.

Description

technical field [0001] The invention relates to a regulating valve, in particular to an anti-leakage regulating valve. Background technique [0002] The air duct and regulating valve of the existing air conditioning system are usually made of galvanized sheet. The ventilation pipe of the regulating valve is connected in series with the air pipe. In the prior art, the ventilation pipe of the regulating valve is usually connected by welding, and the panels on the four sides are welded sequentially. Due to the large number of welds, after long-term use, the welds are prone to rust and corrosion, resulting in air leakage from the regulating valve, which affects the efficiency of the air conditioning system. Contents of the invention [0003] The object of the present invention is to provide an anti-leakage regulating valve connected by sheet metal and riveting. [0004] For achieving above object, the technical scheme that the present invention takes is: [0005] An anti-l...
