具体实施方式
下面结合附图详细说明本发明的具体实施方式，其作为本说明书的一部分，通过实施例来说明本发明的原理，本发明的其他方面、特征及其优点通过该详细说明将会变得一目了然。在所参照的附图中，不同的图中相同或相似的部件使用相同的附图标号来表示。
本发明针对目前气体密封元件密封性能检测领域内的存在的检测周期较长，不易长期监测现象，提出一种基于多种加速试验方法的气体密封性能综合检测系统，实现气体密封元件密封性能的快速检测，减少测试周期，降低试验成本目的。如图1-4所示，本发明提供的气体密封性能模拟综合检测系统的舱脚1、舱体2和舱顶7利用焊接手段固定在一起，所述舱脚1、舱体2、舱顶7、舱门6组成装置的基本结构。所述舱体2为整个系统的主体设备，其它元件大都依附在所述舱体2上。所述舱门6可以人为打开或关闭，主要是保证所述被测气体密封元件12能够自如的通过。所述被测气体密封元件12为需要检测被检测气体的密封性能的储气装置，其内充满标识气体和原本所需要存储的气体，要求标识气体不能与所存储气体发生任何物理化学反应。
所述舱体2内设有密封件支撑座13，所述密封件支撑座13的形状并不固定，其主要作用是支撑固定被测气体密封元件12，故此密封件支撑座13的具体形状和结构受被测试气体密封元件12的结构限制，不做具体要求。
本发明的舱体2内设有气体压力传感器11、温度传感器29和标识气体检测仪10，其中，气体压力传感器11固定在所述舱体2的内壁上，气体压力传感器11拥有较大的测量范围，并能实时准确地将检测到的压力数据传输到电脑终端26中。所述温度传感器29用来测量所述舱体内部温度，并将其温度值传输到所述电脑终端26中。所述标识气体检测仪10位于所述舱体2内壁上，其具有较高的准确性，可以精准检测出由被测气体密封元件12泄漏气体中的标识气体的含量，进而计算出泄漏气体的含量，然后将其数据传输到电脑终端26中。
所述舱体2的外底部设有抽气孔3、数据孔4和电源插孔5，所述抽气孔3贯通所述舱体2，并通过管路与气体过滤器18连接。所述气体过滤器18的一端通过管路与所述抽气孔3连接，另一端与所述高压气泵27连接，所述气体过滤器18可以过滤由所述抽气孔3抽出的气体，确保其变成无毒无害的气体排放到大气中。所述高压气泵27通过所述抽气孔3与所述气体过滤器18连接，所述高压气泵27可以将所述舱内2的气体抽出，通过所述气体过滤器18的过滤后变为安全气体释放到大气中，通过这种方式可以降低舱体2内的气压，进而加快被测气体密封元件12的泄漏速度。所述电源插孔5为所述舱体2与外界的电源连接口，其往内通过内部供电线路19与标识气体检测仪10、气体压力传感器11、电灯8和压缩机15连接，往外通过外部供电线路25与外部电源28连接，为整个舱体2内的用电元件提供电力支持。所述数据孔4为所述舱体2与所述电脑终端26之间的数据中介，所述舱体2内的各个传感器测得的数据先通过内部数据传输线路20 到达数据孔4，然后在通过外部数据传输线路24到达所述电脑终端26进行分析计算。所述电脑终端26为整个系统的分析处理机构，也是整个装置的控制中心，所有数据最终都将在该计算机中汇总分析，并且整个装置系统中的各个机构的运行都需要经由所述电脑终端控制执行。电灯8通过所述内部供电线路19提供的电力进行照明，方便所述被测气体密封元件12的移动。
本发明的舱体内设有制冷系统，所述制冷系统包括制冷剂箱17、压缩机15、冷凝器14和制冷管9，其中制冷剂箱17、压缩机15、冷凝器14位于所述舱体2内外壁之间。所述压缩机15的一端通过冷凝剂管道16与所述制冷剂箱17连接，将制冷剂吸入，另一端通过双向管道的制冷剂输出管22和制冷剂回流管21与冷凝器14连接，制冷剂在被吸入到压缩机15之后经过压缩会变成高温高压的气态制冷剂，然后通过制冷剂输出管22被输送到冷凝器14中，在冷凝器14中制冷剂会开始进行放热，通过冷凝放热之后，高温高压的气态制冷剂会变成低温低压的液态制冷剂，最后通过制冷剂输出管22进入到制冷管9中，低温低压的液态制冷剂进入到制冷管9之后会迅速的吸热蒸发，最终变成等温等压的气态制冷剂，之后气态制冷剂会再次通过制冷剂回流管21被压缩机15吸入压缩，继续进行制冷循环。随着制冷剂的蒸发吸热，所述舱体2中的温度也随之降低，最终实现了加速所述被测气体密封元件12的制冷的作用，实现被测气体密封元件12的泄漏速率的目的。所述制冷管9为圆环形管道，位于所述舱体2的内壁上，从上到下均匀排布，其中部分制冷管受到舱门的限制，其形状为缺失一部分弧度的扇形环装管路，其作用是通过制冷功能降低所述舱体2内部的测试温度，进而加快被测气体密封元件12的泄漏速度，实现加速试验的目的。
下面，参照图1～图4并结合上述结构描述，对本发明的气体密封性能 模拟综合检测系统的使用方法进行描述：
实验开始之前，首先将混有标识气体和预存储气体的被测气体密封元件12放入到舱体2中，并记录被测气体密封元件12的初始气体压力和容器体积到电脑终端26，并利用密封件支撑座13将其固定，然后封闭舱门6。在电脑终端26中输入被测气体密封元件12所处的初始环境(温度、压强)和检测时长(需要使用的时间)，系统根据输入量进行自动分析计算，最终在原有初始环境基础上得出加速试验应该维持的温度、压强和加速之后的检测时长，进而在不改变被测气体密封元件12失效机理的前提下，通过强化试验条件，使被测气体密封元件12加速泄漏，以便在较短时间内获得其各项泄露参数。
然后电脑终端26通过外部数据传输线路24、数据孔4、内部数据传输线路20下达的指令给高压气泵27、压缩机15使其开始工作。高压气泵27通过抽气管道23、抽气孔3、气体过滤器18抽取舱体2内的空气，使得舱体2内的气压快速下降到指定数字后关闭抽气孔3。同时压缩机15开始工作，通过冷凝器14、制冷管9开始制冷，直到舱体2内温度下降到指定值后维持该温度值不变。舱体2内的温度、气体压力和标识气体浓度均通过气体压力传感器11、温度传感器29和标识气体检测仪10来检测，并及时将检测到的数值通过内部数据传输线路20、数据孔4、外部数据传输线路24反馈到电脑终端26中，电脑终端26会根据反馈回来的数值变化及时调整指令，使得舱体2内维持在稳定的设定温度值和气体压力值。当系统测试时间达到电脑终端26的预先设定时间时，标识气体检测仪10会将最后的测量值传输到电脑终端26中，测量完成抽气孔3打开，高压气泵27工作抽出舱体2内部气体，待舱体2内部泄漏气体排出后，可打开舱门6，等待一段时候后取出被测试气体密封元件12即可。
本发明的基于多种加速试验方法的气体密封性能综合检测系统可以在 保证不改变气体密封元件失效机理的前提下，通过强化试验条件，使受试气体密封元件加速泄漏，以便在较短时间内获得其各项泄露参数，进而对其密封性能做出评估。
以上所述是本发明的优选实施方式而已，当然不能以此来限定本发明之权利范围，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和变动，这些改进和变动也视为本发明的保护范围。
