Description

一种高压眼镜阀
技术领域
本发明涉及一种阀门，特别是涉及一种高压眼镜阀。
背景技术
目前使用的眼镜阀，阀板与阀座之间仅采用O形圈密封，密封性差，无法适用于高压环境。
发明内容
为了克服现有眼镜阀上述缺点，本发明提供一种采用三道密封结构，既可多级降压又可耐高压的高压眼镜阀。
本发明解决其技术问题所采用的技术方案是一种高压眼镜阀，包括左阀体、波纹管、阀板、丝杆、左螺母、右螺母、右阀体、左阀座、右阀座，阀板固定在丝杆中部，丝杆的左端通过左螺母安装在左阀座上，丝杆的右端通过右螺母安装在右阀座上，左、右阀体与左、右阀座之间分别焊有波纹管，左、右阀体上分别装有左、右支承板，丝杆穿过左支承板通过限位板与左阀体固定连接，丝杆穿过右支承板通过限位板、压盖与右阀体连接，阀板与左、右阀座之间采用三道密封结构，第一道采用同心圆交替相嵌的三角螺纹结构，第二道采用金属O形圈密封，第三道采用特种高分子材料的软密封。
本发明的有益效果是阀板与阀座之间采用三道密封结构，既可以耐高压又可以实现多级降压的目的，提高了阀门的密封性。
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2是本实施例中密封结构10的局部放大图。
图1、2中：1. 左阀体；2. 限位板；3.左支承板；4.丝杆；5.波纹管；6.左螺母；7.左阀座；8.阀板；9.右螺母；10.密封结构；11.右阀座；12.压盖；13.右支承板；14. 右阀体；15.三角螺纹；16.金属O形圈；17.特种高分子材料。
具体实施方式
如图1所示，一种高压眼镜阀，包括左阀体1、波纹管5、阀板8、丝杆4、左螺母6、右螺母9、右阀体14、左阀座7、右阀座11，阀板8固定在丝杆4中部，丝杆4的左端通过左螺母6安装在左阀座7上，丝杆4的右端通过右螺母9安装在右阀座11上，左阀体1和左阀座7之间以及右阀体14和右阀座11之间分别焊有波纹管5，左、右阀体上分别装有左支承板3和右支承板13，丝杆4穿过左支承板3通过限位板2与左阀体1固定连接，丝杆4穿过右支承板13通过限位板、压盖12与右阀体14连接，阀板8与左、右阀座之间采用三道密封结构10，如图2所示，第一道采用同心圆交替相嵌的三角螺纹结构15，第二道采用金属O形圈密封16，第三道采用特种高分子材料的软密封17。
当丝杆4转动，驱动左螺母6和右螺母9旋转，在波纹管5的作用下，带动左阀座7和右阀座11挤压阀板8，同时挤压它们之间的密封结构10，由于采用三道密封结构，在高压环境中，能够起到更好的密封效果。
