Description

高温眼镜阀的密封装置
技术领域
本发明涉及一种眼镜阀，特别是涉及一种眼镜阀的密封装置。
背景技术
眼镜阀是一种由盲板、透板等组合而成的形式眼镜的阀板机构，沿阀座密封面作往复直线移动，实现截断、开通功能的特种阀门。此阀门只能用于低于250°C的介质管道中。由于高温（400~800°C）工况的需要，橡胶密封圈的耐温不足，会发生泄露。目前，国内有不少厂家会在阀体和伸缩体内开槽，通循环冷却水，但效果不佳，最多能维持10分钟的350°C的高温。通过查阅国内外相关资料，还没有制造出能在400~800°C的高温工况条件下安全工作的阀门。
发明内容
为了克服现有眼镜阀上述缺点，本发明提供一种能在400-800°C的高温工况条件下安全工作的密封装置。
本发明解决其技术问题所采用的技术方案是高温眼镜阀的密封装置，包括阀板以及与之接触的伸缩体和阀体，阀板上设置T形凸面，伸缩体和阀体上设置T形凹面，T形凸面的斜面与T形凹面的斜面相抵接，形成两道金属硬密封，伸缩体和阀体上T形凹面的平面处设置软密封件，软密封件与T形凸面形成一道软密封。
进一步的，软密封件为固定连接的波纹管以及柔性石墨环，柔性石墨环与T形凸面形成一道软密封。
再进一步的，柔性石墨环与与T形凸面的接触面为曲面。
本发明的有益效果是：
1、采用两道斜面硬密封和一道柔性石墨软密封的三道密封结构，保证了阀门的密封性能；
2、采用斜面硬密封在同等条件下增加了密封面的面积，减小泄漏，采用柔性石墨软密封可使用在高温工况，在400-800°C的高温工况条件下可以安全工作；
3、采用波纹管与柔性石墨结合的形式，利用波纹管的高弹性，在柔性石墨环磨损后仍可压紧密封面，有效保证阀门的密封性;
4、柔性石墨环采用曲面形式可增大密封面积，减小泄漏。
附图说明
下面结合附图和实施例对本发明作进一步说明。
图1是本实施例结构图。
图1中：1. 阀体；2. 阀板；3. 伸缩体；4-1. 波纹管A；4-2.波纹管B；5-1. 柔性石墨环A；5-2. 柔性石墨环B；6-1. T形凸面A；6-2. T形凸面B；7-1. T形凹面A；7-2. T形凹面B。
具体实施方式
如图1所示，高温眼镜阀的密封装置，包括阀板以及与之接触的伸缩体3和阀体1，阀板2上设置T形凸面A6-1和T形凸面B6-2，阀体1上设置T形凹面A7-1，伸缩体3上设置T形凹面B7-2， T形凸面A6-1和T形凸面B6-2的斜面与T形凹面A7-1、T形凹面B7-2的斜面相抵接，形成两道金属硬密封，伸缩体3 的T形凹面B7-2和阀体1上T形凹面A的平面处设置软密封件，软密封件为与固定连接的波纹管A4-1以及柔性石墨环A5-1，以及与伸缩体3固定连接的波纹管B4-2以及柔性石墨环B5-2，柔性石墨环A5-1与T形凸面A6-1形成一道软密封，柔性石墨环B5-2与T形凸面B6-2形成一道软密封。再进一步的，柔性石墨环A5-1与T形凸面A6-1的接触面为曲面，柔性石墨环B5-2与T形凸面B6-2的接触面为曲面。
