Description

Technical Field

[0001] The utility model relates to the technical field of air valves, and specifically relates to a high-sealing air valve structure. Background Technique

[0002] The air volume regulating valve, also called the air damper, is an indispensable end accessory of the central air conditioner in the ventilation, air conditioning and air purification projects of industrial plants and civil buildings. It is generally used in the air conditioning and ventilation system pipelines to regulate the air volume of the branch pipes, and can also be used for the mixing regulation of fresh air and return air.

[0003] However, it still has some disadvantages. For example: when the traditional air valve regulates the air volume, it cannot adjust the size of the air outlet of the air valve arbitrarily according to the on-site situation, and when the air valve is in the closed state, the sealing performance is poor, and air leakage and other situations are likely to occur.

[0004] To solve the above problems, a high-sealing air valve structure is proposed in this application. Content of the Utility Model

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model starts the driving motor by setting an adjusting component, and the rotation of the driving motor drives the threaded sleeve to rotate. Under the rotation of the threaded sleeve, the threaded rod is retracted into the threaded sleeve. At this time, the movable rod movably connected to the upper end of the threaded rod drives the movable rod and the fixed rod to rotate under the pulling of the threaded rod, and the connecting plate fixedly connected to the fixed rod will also rotate together. The connecting block and the wind shield plate fixedly connected at one end of the connecting plate will rotate horizontally together. The threaded rod can be retracted back and forth by rotating the threaded rod, so that we can quickly adjust the gap between the wind shield plate and the connecting pipe according to the on-site conditions, adjust the air volume of the pipeline, and improve the practicability of the air valve. The provided sealing gasket can increase the sealing between the wind shield plate and the connecting pipe. BRIEF DESCRIPTION OF THE DRAWINGS
