AI Technical Summary

Technical Problem

In existing vacuum coating equipment, the valve device has a large shaft diameter, occupies a lot of space, and is subjected to uneven force, resulting in high cost and low efficiency.

Method used

Two symmetrically arranged short-shaft valve shafts are used, combined with cylinders and connecting rod assemblies. The valve plate assembly is restricted from shaking by a limiting structure, and the shaking range is limited by springs and guide pillars. The connecting rod assembly is connected at the center position to achieve efficient opening and closing of the valve plate and improve sealing performance.

Benefits of technology

It enables efficient opening and closing of the valve plate assembly, improves sealing and force transmission efficiency, reduces the space occupation and cost of parts, and enhances torsional stiffness.
