Description

Technical Field

[0001] The utility model relates to the technical field of transmission valves, and more specifically, to a rectangular vacuum transmission valve. Background Art

[0002] Vacuum gate valves come in various styles, typically with round or rectangular orifices. Rectangular gate valves are typically used to transfer components between two chambers in a vacuum system. They serve as a barrier when closed. Opening and closing rectangular valves require vibration-free operation to avoid damaging the chamber's status and function, nor the condition of the components being transferred. With increasingly competitive industry conditions, product upgrades are essential to expand product applications and create greater value. Rectangular vacuum transfer valves, as high-vacuum valves, are commonly used in vacuum coating systems, suitable for coating thin and wide surfaces. They primarily include dual-plate, single-plate, and single-plate direct-insert types. This product utilizes a dual-plate, dual-plate, dual-plate structure. The dual-plate, dual-plate structure includes a valve plate, auxiliary plate, retainer, stopper plate, and connecting rod. During the moment of opening and closing, the plates contact the valve chamber and retainer, and the dual plates move within the inner grooves of the bars. This can affect the stability of the valve during reclosing, and metal-to-metal contact can cause impact and vibration. Utility Model Content
