—种高压眼镜阀
[0001 ] 本专利技术涉及一种阀门,特别是涉及一种高压眼镜阀。
技术介绍
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。
技术实现思路
为了克服现有眼镜阀上述缺点,本专利技术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。本专利技术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。本专利技术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专利技术作进一步说明。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 ...
