High-temperature high-pressure resistant concentric two-way rotary joint

Abstract

The invention discloses a high-temperature high-pressure resistant concentric two-way rotary joint which comprises a gas-in seat and an outer sealing cylinder, wherein one end of the outer sealing cylinder is clamped on a sealing cylinder cover of the gas-in seat; a sealing ring is also arranged between the outer sealing cylinder and the sealing cylinder cover; a raised butt-joint cylinder is arranged at the middle of the gas-in seat; an inner gas-in pipe is arranged at the gas-in end of the butt-joint cylinder through a gas-in joint; an outer guide cavity is formed between the periphery of the butt-joint cylinder and the outer sealing cylinder; an outer gas-out pipe communicated with an outer backflow cavity is arranged on the side wall of the outer sealing cylinder through the gas-in joint; the gas-out end of the butt-joint cylinder is in contact with a gas-out butt-joint pipe through an inner graphite sealing ring; and the inner graphite sealing ring is positioned in an inner graphite ring groove of the butt-joint cylinder. The concentric two-way rotary joint disclosed by the invention adapts to the long-time work in a high-temperature high-pressure environment through the multiple sealing, oil charging lubrication, gas guide treatment, pressure balancing treatment and the like.

Description

technical field [0001] The invention relates to the technical field of retort pots, in particular to a high temperature and high pressure resistant concentric two-way rotary joint. Background technique [0002] The rotary joint is a rotary joint used to feed working gas into the rotary sterilizer. The compression device in the rotary sterilizer needs compressed air to make the cylinder work, but because the cylinder needs two channels for air in and out, and The working environment in the kettle is harsh, and ordinary rotary joints cannot meet the work requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high temperature and high pressure resistant concentric two-way rotary joint. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a concentric two-way rotary joint resistant to high temperature and high pressure, including an air inlet seat and ...
