AI Technical Summary
Existing fluid conveying devices cannot completely block the flow when adjusting the flow rate because the gap between the actuating plates on the drive rollers is too large, and the fluid pushes the actuating plates to rotate, making it difficult to adjust the flow rate to a small size.
The system employs a flow-blocking block and sealing sleeve structure. Through the cooperation of a screw and an adjusting disc, the flow-blocking block and sealing sleeve can be moved to adjust the flow rate. The arc-shaped flow guide surface combined with rounded corners ensures complete obstruction and flow guidance.
It enables precise adjustment of fluid flow rate and stable control of small flow rates, while facilitating the replacement of the sealing sleeve, thus improving the efficiency and reliability of the device.
