Analysis And Calculation Of The Strength Of High-pressure Test Tank Quick Opening Device

In the production of the chemical industry，many pressure vesselsbe dued to the requirements of the actual working conditions, and the needfor frequent open-closed-door cover. To solve this problem, a wideapplication and development opportunities be got with a variety of quickopening device, which clamp quick closure of its simple structure, easyassembly and disassembly be widely used. At present, design rules be gotwith the two clamp of small-diameter quick opening device. But thedetailed guidelines for the research and application of large-diameter threeclamp quick opening device not be found in the high-pressure container.To solve this problem, based on engineering practice, the following workbe made:Firstly, the application advantages of three large-diameter clampquick opening device be analyzed comparatively,and the two clamp quickopening device strength analysis and calculation be referenced to analyzethe intensity of the three clamp quick opening device (clamps, bolts,flanges, C-ring), and the three clamp quick opening device designformulas be deduced, and the more clamp quick opening equipment designand calculation rules be explored on this basis.Secondly, on the basis of the clamp quick opening device design rulesin Chapter13of the HG20582and three clamp quick opening device strength analysis to derive formulas, design calculations and strengthcheck of be carried out.Thirdly, based on software of ansys, finite element analysis of threeclamp quick opening device be carried out, including constructing finiteelement model, Solving draw relevant stress cloud, the correctness of thederivation formula be tested by comparison.Lastly, to measure the clamp quick opening device-related parts ofthe stress and strain be used resistance strain testing techniques, and to getconclusion be analyzed comprehensively.
