Abstract

The invention discloses a multi-layer rubber sealing ring sealing device, which is suitable for sealing the connection between the cavity mouth of the vacuum cavity and the cavity cover, and includes several rubber sealing rings, and a surrounding ring is provided at the vacuum cavity facing the cavity cover. The accommodating grooves at the mouth of the cavity and the rubber sealing rings are accommodated in the accommodating grooves one by one and protrude from the accommodating grooves. There is a cooling groove facing the cavity cover between adjacent accommodating grooves. A corresponding hollow cooling pipe is accommodated, and an air extraction channel is provided on the side wall of the vacuum cavity. One end of the air extraction channel communicates with external vacuum equipment, and the other end of the air extraction channel communicates with the cooling groove respectively. The object of the present invention is to provide a multi-layer rubber sealing ring sealing device with simple and compact structure, good anti-leakage performance and long service life with multi-layer 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...
