Sealing and damping device and air inlet pipe assembly

The invention discloses a sealing and damping device, and relates to the technical field of compressed air energy storage, the sealing and damping device mainly comprises a damping sleeve and a sealing connecting piece, the damping sleeve can be embedded in a plug of a gas storage, and an air inlet pipe can be installed in the damping sleeve; when the damping sleeve is embedded in the plug of the gas storage, the end, close to the gas storage, of the damping sleeve can be connected with the gas inlet pipe in a sealed mode through the sealing connecting piece. The invention further discloses an air inlet pipe assembly which comprises an air inlet pipe and the sealing damping device. Effective shock absorption of the air inlet pipe can be achieved, the problem that in the prior art, the pipe wall of the air inlet pipe is separated from concrete of a gas storage plug, and an air leakage channel is generated is solved, and the air inlet pipe is convenient to replace. 本发明公开一种密封减震装置，涉及压缩空气储能技术领域，主要包括：减震套管和密封连接件，其中，
