【摘要】：天然气快开盲板是天然气输送管线上安装在气体杂质过滤器等容器设备端部可以实现快速启闭的关键装置,其一般由高颈法兰、门盖、锁紧机构、密封结构、安全联锁机构、启闭机构等组成。随着我国天然气管网的大力建设,天然气快开盲板的需求越来越旺盛。目前我国输气管线上应用的快开盲板主要依赖进口,为此,国内某石油公司联合厂家和高校共同完成了新型高压、大直径(压力达12.6MPa,内径为Φ1550mm)天然气快开盲板装置的开发,其中对橡胶密封圈结构进行了较大改进。本论文就新型快开盲板结构中的关键技术鞍形密封圈的密封性能做了一系列仿真分析和相关性能试验。论文介绍了新型天然气过滤器锁环式快开盲板密封圈的开发背景及过程,并借助于功能强大的非线性有限元软件,针对影响新型橡胶密封圈结构性能的各种因素进行了参数化分析,同时研究分析了国外主要同类产品的密封圈特性,结合相关的试验数据,进行了对比,得出新型鞍形橡胶密封圈具有良好的密封性能、方便的启闭功能,完全适合天然气快开盲板的密封要求。论文的主要工作归结如下：1.围绕天然气快开盲板采用的密封圈形式,研究分析了国内外主要应用的快开盲板密封结构原理和特点,介绍了我们开发的新型鞍形密封圈快开盲板的结构原理,并对上述各种形式的结构进行了对比分析。2.利用有限元分析软件ABAQUS对影响鞍形橡胶圈密封性能的参数进行分析,得出其合理的取值范围;同时完成了传统“C”形橡胶密封圈、KEMLCOK型“O”形密封结构密封性能的仿真分析及性能对比。3.完成了高压大直径快开盲板采用新型鞍形密封圈结构的密封性能试验和开关门盖“防卡”性验证,显示新型密封圈具有良好的密封性能和门盖启闭时的“防卡”浮动性能。4.阐述了橡胶材质密封圈的“电子老化”原理,结合相关的材料性能试验数据,完成了对鞍形密封圈使用寿命的预估分析。
[Abstract]:The natural gas fast opening blind plate is the key device which can realize the quick opening and closing at the end of the container equipment such as gas impurity filter installed on the natural gas pipeline, which is generally made up of high neck flange, door cover, locking mechanism and sealing structure. With the construction of natural gas network in our country, the demand for the fast open blind board of natural gas is more and more strong. At present, the fast open blind board used in the gas pipeline in our country mainly depends on the import. Therefore, a new type of high pressure, large diameter (pressure 12.6MPa, inner diameter 桅 1550mm) natural gas fast open blind board has been developed by a domestic oil company and a university. The structure of rubber seal ring has been improved greatly. This paper has done a series of simulation analysis and related performance test on the key technology of the new type fast open blind plate structure, saddle seal ring, and introduced the new type of seal ring. Development background and process of gas filter locking ring type fast open blind plate seal ring. With the help of the powerful nonlinear finite element software, various factors affecting the structural performance of the new rubber seal ring are analyzed, and the characteristics of the main foreign products of the same kind are also studied and analyzed. According to the experimental data, the new type saddle rubber seal ring has good sealing performance and convenient opening and closing function. The main work of this paper is as follows: 1. The sealing ring around the natural gas fast blind plate. This paper studies and analyzes the structure principle and characteristics of the fast open blind plate which is mainly used at home and abroad, and introduces the structure principle of a new type of saddle ring fast open blind plate developed by us. By using finite element analysis software ABAQUS, the parameters affecting the sealing performance of saddle rubber ring are analyzed, and the reasonable value range is obtained. At the same time, the traditional "C" rubber sealing ring is completed. Simulation Analysis and comparison of Seal performance of KEMLCOK Type "O" Seal structure. 3.The sealing performance test and opening and closing cover of high pressure large diameter fast opening blind plate with new saddle seal ring structure have been completed. Anti-card "sex verification." It shows that the new seal ring has good sealing performance and the floating property of "anti-blocking" when the door cover is opened and closed. The principle of "electronic aging" of rubber seal ring is expounded, and the related material performance test data are combined. The service life of saddle seal ring is estimated and analyzed.
