AI Technical Summary
Technical Problem
The existing louvered valves in cement kiln industry have poor sealing performance, resulting in internal leakage and making it impossible to completely cut off the fluid passage.
Method used
A high-sealing louver valve is designed, which adopts an elastic sealing structure, including a rubber sealing gasket and abutment. The elastic sealing structure of the blades forms a multi-stage seal by mutual compression, and the synchronous rotation of the blades is achieved by a drive motor and controller to ensure the sealing effect.
Benefits of technology
It effectively improves the sealing performance of the louver valve, reduces fluid leakage, and achieves a tight seal of the fluid passage.

Abstract
The invention belongs to the technical field of louver valves, and particularly relates to a high-sealing-performance louver valve which comprises a valve body, rotating shafts and blades, a plurality of transverse rotating shafts are arranged on the two opposite sides in the valve body, each rotating shaft is provided with a transverse blade, every two adjacent blades are in lap joint to form a sealing face, and the blades are arranged in the valve body. Elastic sealing structures are arranged on the edges of the blades, and when the blades are closed, the elastic sealing structures of the adjacent blades extrude each other to form multi-stage sealing. The elastic sealing structure is arranged, the shutter valve is closed, the valve body gap is completely attached to the blade, the multi-stage sealing effect is achieved, and the problem that when most existing blades are used in cooperation, the sealing performance is not good, and inner leakage is caused is solved.
