Abstract

The invention discloses a multilayer rubber sealing ring sealing device suitable for sealing the joint of a cavity port and a cavity cover of a vacuum cavity. The multilayer rubber sealing ring sealing device comprises a plurality of rubber sealing rings. The vacuum cavity is provided with containing tanks around the cavity port, the containing tanks are just opposite to the cavity cover, the rubber sealing rings are contained in the containing tanks in one-to-one correspondence and protrude the containing tanks, a cooling tank just opposite to the cavity cover is arranged between the neighboring containing tanks, and cooling pipes in hollow structures are contained in the cooling tanks in one-to-one correspondence; and air exhaust channels are also arranged on the side wall of the vacuum cavity, one ends of the air exhaust channels are communicated with external vacuum equipment, and the other ends of the air exhaust channels are respectively communicated with the cooling tanks. The invention aims to provide the multilayer rubber sealing ring sealing device having the advantages of simple and compact structure, good anti-leakage performance, long service life and multilayer sealing effect.

Description

technical field [0001] The invention relates to a multi-layer rubber sealing ring sealing device, in particular to a device for sealing the chamber cover of a vacuum chamber. Background technique [0002] For a long time, most of the flat seals of the cavity are sealed with a single rubber strip or an "O" ring structure. The operating temperature of the rubber strip is -40°C to 60°C. The requirements for sealing materials and seals are: 1. .The material has good compactness and is not easy to leak medium; 2. It has appropriate mechanical strength and hardness; 3. It has good compressibility and resilience and small permanent deformation; 4. It does not soften or decompose at high temperature, and does not harden or brittle at low temperature 5. It has the flexibility to bond with the sealing surface; 6. It has good aging resistance and durability; 7. It is convenient to process and manufacture, cheap in price, easy to obtain materials, etc. A single rubber strip cannot meet...
