Description

一种四密封航油阀的密封结构的制造工艺
技术领域
本发明涉及一种四密封航油阀的密封结构的制造工艺,特别是针对腐蚀性较高的油路储运系统中的液体截断。
背景技术
航油阀是近几年常用的油路储运系统截止阀,安装在油路储运系统中,利用双阀瓣来实现双向密封,同时利用硬密封和软密封相结合来实现可靠性较高的密封。若阀发生泄露,不仅会使阀腔内充满液体,也会使液体泄露到管路外。故阀的密封性要求极高,一旦气体泄漏,则阀失效。
现有的航油阀软密封的O形密封圈一般采用橡胶硫化成型,该方式粘结强度大,可以高达16.0MPa,满足油路系统的压力大小。但是,由于橡胶存在老化现象,同时可能与油路中的某些液体成分产生化学反应,所以在使用过程中要经常更换阀瓣,甚至不慎时会发生泄露。
发明内容
本发明的目的是克服现有技术的不足,提供一种四密封航油阀的密封结构的制造工艺。
1)将四密封航油阀的密封结构的PTFE密封圈放入低温等离子反应器中,使用99.999%的Ar等离子气体,采用外电极、13.56MHz射频功率发生器来进行流动式射频放电,放电气体压强40-50Pa、放电功率50-100W、放电时间5-10min;
2)将处理后的PTFE密封圈在空气中放置5-10min;
3)将阀瓣的梯形沟槽浸泡在0.5%APS的甲苯溶液中10-12h,温度50-60℃,再用乙醇超强声清洗;
4)将处理后的阀瓣在100-120℃下干燥5-10min;
5)在PTFE密封圈和梯形沟槽之间引入JF205-1环氧粘合剂,采用60℃持续3h的固化工艺,将两者粘结。
所述的四密封航油阀的密封结构包括阀芯、阀瓣、阀座、PTFE密封圈、梯形沟槽;阀瓣对称设置在阀芯外。所述的阀瓣为两个,均开有梯形沟槽。
使用本发明,在实现双密封的同时,保证了软密封的可靠性。一方面,PTFE密封圈的抗腐蚀、耐高温性能良好,可以避免油路中的液体对密封圈的腐蚀以及频繁开关阀门对密封圈的磨损;另一方面,使用低温等离子处理与环氧粘合剂相结合的技术,可以使PTFE密封圈与阀体粘结强度提高。经过试验,在200℃/3h的处理条件下,粘结仍有效,在实际使用中,其粘结性能和耐高温性能良好,能够承受300℃的高温。
