AI Technical Summary
Existing airflow valves are complex, bulky, and have poor control flexibility when there are multiple pipeline requirements. They also have poor sealing performance and high maintenance costs, making them unsuitable for complex and precision instruments. Furthermore, traditional designs require multiple sub-control valves, which are difficult to operate and increase application costs.
The multi-channel intake valve driven by an electric motor uses a transmission mechanism of meshing active and driven bevel gears, combined with a valve control mechanism and sealing gaskets, to achieve independent or simultaneous opening and closing control of one or more valves, reducing the number of pipes and valves. Electromagnetic force is used to control the opening and closing of the valves.
This invention achieves a multi-channel air intake valve that is compact, small in size, low in cost, easy to maintain, and has a long service life, reducing space occupation and material costs while improving control flexibility and sealing performance.
