Multi-functional multi-specimen sealing gasket service life evaluation testing apparatus

Abstract

The invention relates to a multi-functional multi-specimen sealing gasket service life evaluation testing apparatus which comprises a gasket loading and load measuring system (56) and a medium given system (51). The apparatus is characterized in that the air given end of the medium given system (51) is connected with the air inlet end of a medium sealing system (53), the medium sealing system (53) is positioned inside of a temperature controlling and measuring system (54), a cooling thermal insulation system (57) is placed above the medium sealing system (53), and a leakage rate measuring system (55) is positioned on one side of the temperature controlling and measuring system (54); the medium sealing system (53), the temperature controlling and measuring system (54) and the cooling thermal insulation system (57) are connected respectively through stress bolts (14) of the gasket loading and load measuring system (56); and a data acquisition and control system (52) is respectively and electrically connected with the medium given system (51), the medium sealing system (53), the temperature controlling and measuring system (54), the leakage rate measuring system (55) and the cooling thermal insulation system (57).

Description

technical field [0001] The invention relates to the field of sealing technology, in particular to a multifunctional multi-specimen sealing gasket life evaluation test device which adopts a new structure and a high-precision sensor to measure gasket sealing performance parameters, conduct an accelerated life test, and accurately predict the life of the 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] Although there have been many evaluation methods for the sealing life of gaskets, these methods are mainly based on the derivation of mechanical theory and the experimental r...
