Bolt-spacer-flange connecting and sealing safety evaluating system

Abstract

The invention provides a bolt-spacer-flange connecting and sealing safety evaluating system. The bolt-spacer-flange connecting and sealing safety evaluating system is characterized by comprising a data processing module, a data calculating module, a safety evaluating module and a spacer selecting module; the data processing module is used for processing tested basic data about a bolt, a spacer and a flange to establish a relationship model among the bolt, the spacer and the flange; the data calculating module is used for calculating the system leakage rate on the basis of the relationship model obtained by the data processing module among the bolt, the spacer and the flange; the safety evaluating module is used for comparing the leakage rate obtained by the data calculating module with a safety performance level preset by the system to obtain a system leakage rate level; the spacer selecting module is used for selecting the spacer needed by the system on the basis of the system leakage rate level obtained by the flange safety evaluating module. According to the safety evaluating system, safety management of a bolt-spacer-flange connecting system can be improved.

Description

technical field [0001] The invention relates to a safety evaluation system, in particular to a bolt gasket flange connection sealing safety evaluation system. Background technique [0002] Flange connection is a static sealing structure of pressure vessels, which is widely used in petrochemical plants. Flanges are divided into container flanges and pipe flanges. Vessel flanges have been widely used as important connecting components, and they are required to have sufficient strength and reliable sealing performance. Its sealing performance depends on the deformation coordination relationship of bolts, gaskets and flanges. Since many pipelines and containers operate under high temperature and high pressure conditions for a long time, and the temperature has a great influence on the various components of the flange connection system, the sealing performance of the flange connection at high temperature is a coupling problem between the temperature field and the structural fie...

Problems solved by technology

Since many pipelines and containers operate under high temperature and high pressure conditions for a long time, and the temperature has a great influence on the various components of the flange connection system, the sealing performance of the flange connection at high temperature is a coupling problem between the temperature field and the structural field. Temperature will cause different degrees of thermal expansion and contraction of various components, and the deformation coordination relationship is relatively complicated. It is difficult to accurately obtain the deformation coordination relationship between bolts, gaskets and flanges, so that the flange connection of bolts and gaskets cannot be effectively sealed. assess the safety performance of
