The working principle of a rotary valve (direct blow type) mainly involves using the valve’s structure to control the flow of air in and out. Here’s a basic overview:
- Rotary Valve Structure: A rotary valve typically consists of a valve body and a rotating disc. The disc rotates within the valve body, altering the relative position between the disc and the body to regulate the airflow.
- Direct Blow Design: The direct blow type is designed with a straight airflow path, minimizing resistance and improving flow rate and efficiency.
- Airflow Control: When the disc rotates to a specific position, the inlet and outlet ports of the valve body align, allowing air to flow in or out. Conversely, when the disc rotates to another position, the airflow path closes, stopping the flow.
- Applications: This type of valve is commonly used in pneumatic conveying, packaging, and automated production lines, enabling quick and effective control of gas flow.
Rotary valves of this type are characterized by their simple structure, ease of operation, and precise flow control.
