Abstract

本发明公开了一种角向唇状橡胶密封圈，密封圈上端设有径向唇口和轴向内唇，轴向外唇和轴向内唇之间设有轴向沟槽，所述轴向外唇上端设有与密封圈主体连为一体的径向唇口，所述径向唇口和轴向外唇之间设有径向沟槽。本发明是在活塞杆通过结合处纵、横两个方向能同时起密封作用的密封圈，是除O形圈、Y形圈之外的又一种型式的新结构密封圈。

Description

角向唇状橡胶密封圈
技术领域
本发明属于一种橡胶密封件，具体说是一种能同时密封结合处纵、横两个方向的角向唇状橡胶密封圈。
背景技术
Y型密封圈因其具有密封性能可靠；摩擦阻力小，运动平稳； 耐压性好，适用压力范围广；结构简单，价格低廉；安装方便等优点，其使用寿命也高于O型密封圈，而广泛应用于往复动密封装置中。
现有橡胶密封圈，当活塞杆通过结合处时，活塞杆上要有密封件作轴向密封，同时结合面也要有密封件作径向密封，但是现有的橡胶密封圈无论是O形密封圈还是Y形密封圈，均是对结合处一个方向进行密封，无法对径向和轴向两个方向同时进行密封 。  
发明内容
本发明设计出一种角向唇状橡胶密封圈，以解决现有密封圈无法同时对径向和轴向同时进行密封的问题。
本发明的技术方案是：包括密封圈主体，所述密封圈上端设有轴向外唇和轴向内唇，轴向外唇和轴向内唇之间设有轴向沟槽，所述轴向内唇上端设有与密封圈主体连为一体的径向唇口，所述径向唇口和轴向外唇之间设有径向沟槽。
本发明的有益效果是:采用本发明设计方案，设计一种对接合处纵、横两个方向（正交或斜交）能同时起到密封作用的新型橡胶密封圈，具有结构简单，制造方便，密封可靠的优点，而且此结构外圈座孔无需精确加工，是除O形密封圈、Y形密封圈之外的又一种新结构的密封圈。
附图说明
图1是发明的结构示意图。
具体实施方式
下面结合附图对本发明作进一步说明。
如图1所示，本发明包括密封圈主体2，密封圈2上端设有轴向内唇7和轴向外唇3，轴向内唇7和轴向外唇3之间设有轴向沟槽6，所述轴向外唇3上端设有与密封圈1主体连为一体的径向唇口5，径向唇口5和轴向外唇3之间设有径向沟槽4。
本发明在普通Y形密封圈的基础上，把Y形密封圈的外圈上平面扩展为径向唇口5，轴向外唇和轴向内唇能起到轴向密封作用，径向唇口起到平面径向密封的作用，实现了在活塞杆通过结合处时对于纵、横两个方向（正交、斜交均可）能同时起到密封作用。
