摘要
简述了带压密封技术的基本原理,论述了带压密封技术的关键金属构件-夹具的两个基本作用:密封保证和刚度保证,提出了夹具的设计准则:良好地吻合性、足够的强度、足够的刚度、合适的密封空腔、接触间隙严密、注剂孔开设、分块合理.以曲梁的有力矩理论为基础,建立了中高压管道法兰夹具的刚度计算公式.同时给出了中高压管道法兰夹具的强度校核公式.
This article describes briefly the basic principle, key metal compo nent--clamp two basic functions： seal and stiffness assurance for online leak sealing technology. Clamps design criterion：fine inosculation, enough strength, enough rigidity, suitable sealing cavity, contact gap close, injecting threaded hole and reasonable subdivision are discussed. The rigidity calculation formula of middle-high pipeline flange clamps are proposed based on the torque theory of the bent beam. It also shows the strength check formula of middle-high pipeline flange clamps.
