AI Technical Summary
Technical Problem
Existing swing valves have poor sealing performance when fibers become entangled, which prevents the valve from blocking the airflow channel and effectively preventing fibers from becoming entangled on the shaft.
Method used
A wear-resistant composite seal is installed at the gap between the shaft and the valve body. The side of the seal is attached to the inner wall of the valve body and matches the shaft through a groove. It is then fixed with a pressure plate and fasteners to achieve a complete seal of the gap.
Benefits of technology
The sealing performance of the swing valve has been improved to prevent fibers from getting tangled in the shaft, ensuring that the valve can tightly close the air inlet and prevent air leakage.

Abstract
The utility model relates to a kind of swing valve of anti-fiber winding, belong to textile dust filtering equipment technical field. Including valve body, the valve body one end has air inlet, the other end has gas outlet, the air inlet and gas outlet are connected airflow line respectively;The rotatable shaft of horizontal arrangement is equipped in the valve body, the rotatable shaft both ends are equipped in valve body by shaft sleeve, valve is set on the rotatable shaft, drive device drives the rotatable shaft swing, drives valve to swing, so that valve is close to air inlet and seals air inlet;Or valve is far from air inlet and opens air inlet;Rotatable shaft both ends and the clearance of valve body are respectively equipped with sealing unit. The sealing unit includes sealing element, the sealing element side is attached to the inner wall of valve body, the sealing element bottom has recess, the recess is clamped on the upper half of rotatable shaft, the sealing element cover rotatable shaft and the clearance of valve body. The application avoids that fiber enters clearance and winds on rotatable shaft, so that valve can tightly close valve air inlet, prevent air leakage.
