Bolt gasket flange connection design expert system

Abstract

The invention discloses a bolt gasket flange connection design expert system and belongs to the technical field of the design of an expert system. The system comprises a database management module, a gasket query module, a flange connection design module, a design result comparison analysis module and a tool module, wherein the database management module is used for updating a bottom layer database; the gasket query module is used for querying a standard gasket and a standard gasket test; the flange connection design module is used for automatically generating a flange connection design specification and a flange joint part drawing according to input working condition data by utilizing standard gasket size data provided by a standard gasket database, data which is provided by a gasket selection expert library and corresponds to gasket materials, gasket types, a medium, a temperature and a pressure and data provided by a bolt database and a flange database; the design result comparison analysis module is used for carrying out key parameter comparison analysis on a design scheme so as to recommend the optimal design scheme; and the tool module is used for providing unit conversion, scientific calculation and system use help. The system solves the technical problem that the bolt gasket flange connection cannot be economically, safely and accurately designed.

Description

technical field [0001] The present invention relates to an expert system, in particular to an expert system for bolt gasket flange connection design Background technique [0002] As a key part of process equipment and pipeline connection, bolted gasket flange connection is often used by engineering designers for its advantages of convenient disassembly, economical safety, and easy replacement. In fact, flange connection is already the most commonly used connection form in pressure vessels and pipelines. According to statistics, there are hundreds of thousands or even millions of flange connections in a large oil refinery. [0003] With the enlargement of the device and the extreme operation conditions, once the seal of the connection joint fails, it will have a serious impact on the entire production process. Therefore, the flange connection design directly affects the safety of production personnel and the safe operation of the production device. The bolted gasket flange c...

Problems solved by technology

Therefore, the design of bolted gasket flange connection will involve flange selection, gasket type and material selection, bolt load calculation, and determination of bolt diameter and number, etc. The design workload is heavy and the steps are cumbersome. are developing corresponding design software

But so far there is still no system software that is universal, practical and recognized by everyone. The reasons for its low utilization rate are nothing more than: (1) The function is simple, and the design, query, and analysis cann
