Abstract

一种双唇橡胶平面密封垫片有橡胶片环,橡胶片环的环周上布有螺栓孔,橡胶片环的两个侧面是垫片密封面,垫片密封面是光滑的平面,其特征在于:垫片密封面的螺栓孔口外有沿螺栓孔口的圆环形密封线,垫片密封面上、沿橡胶片环的环周有内外两道环形密封线。使用时,把本实用新型夹在法兰或筒形缸体与缸盖上相配合的环形平面密封面之间,用螺栓把法兰或筒形缸体与缸盖旋紧。本实用新型的垫片密封面的螺栓孔口外有沿螺栓孔口的圆环形密封线,垫片密封面上、沿橡胶片环的环周有内外两道环形密封线,安装时,密封线对相连的法兰或筒形缸体与缸盖之间的不均匀间隙具有补偿作用,安装后不易产生泄漏,密封性能好。

Description

双唇橡胶平面密封垫片
技术领域
本实用新型涉及一种橡胶平面密封垫片,特别是一种橡胶平面密封垫片的密封唇口。 
背景技术
橡胶平面密封垫片用于设备的法兰之间或筒形缸体与缸盖之间连接的密封。法兰或筒形缸体与缸盖上有相配合的环形平面密封面,环形平面密封面上有螺栓孔。橡胶平面密封垫片有与法兰或筒形缸体与缸盖上的环形平面密封面相配合的橡胶片环,橡胶片环是圆环或异形环,橡胶片环的两个侧面是垫片密封面,橡胶片环的环周上布有与上述环形平面密封面上的螺栓孔相配合的螺栓孔。现有技术中,橡胶平面密封垫片的垫片密封面是光滑的平面。使用时,橡胶平面密封垫片被夹在法兰或筒形缸体与缸盖上相配合的环形平面密封面之间。这种橡胶平面密封垫片的垫片密封面是光滑的平面,而相连的法兰或筒形缸体与缸盖之间的间隙不是很均匀,安装后可能由于密封性能不好而产生泄漏。 
发明内容
本实用新型的目的是为了克服上述不足,提出一种安装后密封性能好的双唇橡胶平面密封垫片。 
本实用新型是用如下方法实现的。 
双唇橡胶平面密封垫片有橡胶片环,橡胶片环的环周上布有螺栓孔,橡胶片环的两个侧面是垫片密封面,垫片密封面是光滑的平面,垫片密封面的螺栓孔口外有沿螺栓孔口的圆环形密封线,垫片密封面上、沿橡胶片环的环周有内外两道环形密封线。 
本实用新型的橡胶片环与法兰或筒形缸体与缸盖上的环形平面密封面相配合,橡胶片环可以是圆环或异形环,橡胶片环的环周上的螺栓孔与所用法兰或筒形缸体与缸盖的环形平面密封面上的螺栓孔相配合。 
使用时,把本实用新型夹在法兰或筒形缸体与缸盖上相配合的环形平面密封面之间,用螺栓把法兰或筒形缸体与缸盖旋紧。 
本实用新型的垫片密封面的螺栓孔口外有沿螺栓孔口的圆环形密封线,垫片密封面上、沿橡胶片环的环周有内外两道环形密封线,安装时,密封线对相连的法兰或筒形缸体与缸盖之间的不均匀间隙具有补偿作用,安装后不易产生泄漏,密封性能好。 
下面结合附图,对本实用新型作进一步地说明。 
附图说明
图1是根据本实用新型的发明方案提出的一种双唇橡胶平面密封垫片的主视示意图; 
图2是图1的A-A剖视示意图。
具体实施方式
图1、图2中,双唇橡胶平面密封垫片有橡胶片环1,橡胶片环的环周上布有螺栓孔2,橡胶片环的两个侧面是垫片密封面3、4,垫片密封面是光滑的平面,垫片密封面的螺栓孔口外有沿螺栓孔口的圆环形密封线5,垫片密封面上、沿橡胶片环的环周有内、外两道环形密封线6、7。
