High-temperature comprehensive property evaluation experimental device of sealing spacer

Abstract

The invention relates to a high-temperature comprehensive property evaluation experimental device of a sealing spacer, comprising a spacer loading system, a flange lifting separation system, a spacerdeformation measuring system, a heating and temperature control measuring system, a cooling heat insulation system, a medium setting system, a medium sealing and leakage rate measuring system and a data acquisition system. The invention has the advantages of high parameter, convenient experiment, compact structure of a whole experimental machine, small occupying area, and the like, takes a low-pressure area as a leakage measuring cavity, enhances the measuring precision of the pressure of the leakage measuring cavity and also effectively avoids the problem of pipeline leakage caused by takinga high-pressure area as a leakage cavity so that the measurement of the sealing property of the spacer is more accurate; and in addition, the flange lifting separation system can solve the problem ofthe difficult bonding and separation of the high-temperature experimental spacer and a flange.

Description

technical field [0001] The invention relates to a high-temperature comprehensive performance evaluation test device for sealing gaskets, in particular to a high-temperature compression rebound performance, creep relaxation performance and sealing performance of gaskets at high temperatures using a new structure and high-precision sensors. The high-temperature comprehensive performance evaluation test device of the comprehensive performance of the sealing gasket. Background technique [0002] Bolt flange gasket seals are widely used in equipment and pipeline connections in the process industry, and gaskets are key components that affect the sealing performance of connections. The sealing of the fluid is achieved through the close contact between the flange and the gasket, relying on the elastic-plastic deformation of the gasket to reduce or block the leakage channel to increase the flow resistance. [0003] In the past 30 years, the sealing characteristics of bolted flange c...
