AI Technical Summary
Technical Problem
The existing two-position five-way valve cannot achieve the function of airflow reversal, and it has a complex structure, high cost, and large size.
Method used
Design a two-position five-way valve with three-layer coaxial air passage. Through spatial structure and motor-driven valve core movement, the airflow can be coordinated between the middle and outer air passages. A single motor can be used to switch between positive and negative pressure, simplifying the structure and reducing costs.
Benefits of technology
It enables efficient switching of airflow between common outlets, reduces costs and size, maintains normal operation of the turbine fan, improves work efficiency, and makes installation and maintenance more convenient.
