Description
technical field [0001] The invention relates to a leak rate test device, in particular to a leak rate test device for pipe joint seals. 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. The pipe joint is a detachable sealed connection, which is an important part in the connection of various sealing devices, and is widely used in pipeline systems such as machinery, petrochemicals, and ships. The failure behavior of the sealed connection is mainly manifested as leakage. Once the dangerous medium leaks, it may cause irreparable economic losses. [0003] The research on the normal and high ...
