Description

一种密封体
技术领域
本实用新型涉及一种高压电控共轨喷油器总成中零部件,具体涉及一种活塞回油节油孔的密封体。
背景技术
现有技术中,德国博世公司推出高压电控共轨燃油喷射系统。在该系统中的核心部件高压电控共轨喷油器总成中控制活塞回油节油孔密封部件由密封钢球和钢球座两部分组成,其结构复杂,对钢球几何形状如表面圆度及表面粗糙度要求非常高,普通钢球难以实现密封,制造加工成本或采购成本较高。
发明内容
为解决上述不足之处,本实用新型提供一种密封体。它既设计合理,结构简单又制造成本较低。
本实用新型的任务是通过下述技术方案实现的,一种密封体,其结构特点是在圆柱体3上设有圆台2和圆锥1组成的密封环带。
本实用新型的积极效果是结构简单,易于加工,密封性能好并且制造成本低。
附图说明
图1为依据本实用新型提出的结构主视图
图2为依据本实用新型提出的结构俯视图
图中1-圆锥,2-圆台,3-圆柱体。
具体实施方式
本实用新型是一种密封体。下面结合附图对本实用新型进一步说明。如图1所示,它由圆锥1、圆台2和圆柱3组成。其中在圆柱体3上端有圆台2和圆锥1组成的密封环带。该密封体为GCr15的轴承钢,易于加工,密封性能好。
