Description

偏心半球阀的阀芯
技术领域
本实用新型涉及偏心半球阀领域,具体属于偏心半球阀的阀芯。
背景技术
   在管道中起截断介质的球阀种类很多,有硬质密封偏心球阀和软密封偏心半球阀,硬密封偏心半球阀的密封是金属对金属,长时间使用后相接触面会相互摩擦,使密封有一定的泄漏,软密封偏心半球阀的密封是金属对橡胶,长时间使用后相接触面不会相互摩擦,密封可达到零泄漏,目前市场上已有的软密封结构在使用时虽然达到零密封的效果,但其结构复杂、安装维修不方便,特别是在容易发生结垢的恶略环境中使用,因结垢现象的产生而影响到阀门的自如开启,降低了工作效率,影响了使用寿命和经济效益。
实用新型内容
本实用新型的目的是提供一种偏心半球阀的阀芯,能够承受高压力的水流冲击,密封圈体与密封板密封设置,且安装拆卸方便快捷,易于操作人员单独进行。
本实用新型的技术方案如下:
偏心半球阀的阀芯,包括有半球体,所述半球体外侧端面设有平面状的阀板,阀板外侧壁上凹腔,凹腔内设有多个凸筋,凹腔外固定设有密封板,密封板与密封圈体贴合密封设置。
所述的密封板与半球体的边缘之间联接有螺栓。
本实用新型能够承受高压力的水流冲击,密封圈体与密封板密封设置,且安装拆卸方便快捷,易于操作人员单独进行。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,偏心半球阀的阀芯,包括有半球体1,半球体1外侧端面设有平面状的阀板2,阀板2外侧壁上凹腔3,凹腔3内设有多个凸筋4,凹腔3外固定设有密封板5,密封板5与密封圈体贴合密封设置,密封板5与半球体的边缘之间联接有螺栓6。
