AI Technical Summary
Technical Problem
In existing vacuum equipment, flange blind plate sealing requires multiple parts to be assembled, which has high material costs and long installation time, resulting in high overall use costs.
Method used
A blind plate assembly structure is designed, including a lower seal, upper gland, flat washer and screws, and sealing is achieved through a screw connection, avoiding the problem of inner connection gap caused by the outer connection of the chamber.
Benefits of technology
It achieves a low-cost and simple installation sealing effect, reduces processing costs, and avoids gas leakage caused by lax sealing under vacuum conditions.

Abstract
The invention discloses a blind plate assembly structure and a use method, multiple groups of blind plate assembly structures are arranged on a reserved flange surface of a vacuum chamber, each group of blind plate assembly structure comprises a lower sealing element, an upper gland arranged above the lower sealing element, a flat washer arranged above the upper gland, and a screw arranged above the flat washer, a first through hole is formed in the center of the lower sealing piece, a second through hole is formed in the center of the upper gland, a third through hole is formed in the center of the flat washer, and the first through hole, the second through hole and the third through hole are arranged in a penetrating mode. The screw penetrates through the first through hole, the second through hole and the third through hole to fix the upper gland and the lower sealing piece. The blind plate has the advantages that the blind plate is simple in structure, low in processing cost due to few materials and convenient to install in the later period, and therefore the blind plate has the advantages of being low in cost and convenient to install in the using process.
