High-temperature and high-pressure air cylinder sealing assembly

Abstract

The invention relates to the technical field of machinery, and discloses a high-temperature and high-pressure air cylinder sealing assembly. The high-temperature and high-pressure air cylinder sealing assembly comprises an upper half air cylinder, a flange I at the bottom of the upper half air cylinder, a lower half air cylinder below the upper half air cylinder, a flange II at the top of the lower half air cylinder, and bolts and nuts for fastening the ends, away from the upper half air cylinder, of the flange I and the flange II. Buckling grooves are formed in the flange I and the flange II. Through the designed buckling grooves, a transmission air channel and a sealing clamping plate, when the operation of the air cylinders is influenced by high-temperature and high-pressure gas, the high-temperature and high-pressure gas passes through the transmission air channel to enter a buckling cavity formed after the buckling grooves in the flange I and the flange II are closed; and high-temperature and high-pressure gas pushes the sealing clamping plate to be clamped with a trapezoidal protrusion formed by the buckling cavity to form self-locking, so that when the upper half air cylinder and the lower half air cylinder tilt with one bolt as a fulcrum, the sealing clamping plate limits separation of the flange I and the flange II to complete sealing compensation, and the two air cylinders are kept in a sealed state.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a high-temperature and high-pressure cylinder sealing assembly. Background technique [0002] The cylinder is a device used to carry the gas medium. Often the gas in the cylinder is used as the power source, output source, etc., causing the gas medium in the cylinder to always be in a state of high temperature and high pressure, so that the high temperature load and The gas high pressure load is very strong, so it is very important for the sealing of the cylinder. [0003] At present, for the sealing of high-temperature and high-pressure cylinders, flange parts are mostly used at the joints of the upper and lower half cylinders for bolt connection, and the pre-tightening force of the bolts is used to make the two flanges contact and seal. Due to the influence of high temperature and high pressure, the cylinder still has a tendency to expand the upper and lower half cylinders, ...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the use of the existing high-temperature and high-pressure cylinder sealing flanges proposed in the background technology, the present invention provides a high-temperature and high-pressure cylinder sealing assembly, which has high-temperature and high-pressure gas as a power source for self-locking, high-temperature and high-pressure gas push The advantage of sealing clamping plate and trapezoidal protrusion to complete the sealing compensation, and maintaining the clamping relationship after the sealing clamping plate is deformed to complete the lower level of sealing compensation, solves the problem of cylinder warping, seal failure, etc. Technical Problems of Bolt Deformation Seal Failure
