Description

一种防擦伤可清洗球阀阀座结构 技术领域
本实用新型涉及机械阀门技术，尤其涉及一种防擦伤可清洗球阀阀座结构。
背景技术
现有的球阀阀座结构，主要由密封圈、刮片、球体、侧阀体、阀座支承等组成，现有阀座结构通道内侧没有工艺卡槽，阀门装配完成后，阀座与球体之间的密封面紧密接触，不能清除密封面堆积的杂质，从而导致密封面容易擦伤。
实用新型内容
本实用新型旨在提供一种防擦伤可清洗球阀阀座结构，能够具有清洗密封面和防止密封面擦伤的功能。
为达到上述目的，本实用新型采用的技术方案如下：
一种防擦伤可清洗球阀阀座结构，包括球体、阀座支承和侧阀体，所述侧阀体内表面为台阶状，包括第一台阶和第二台阶；所述阀座支承外圆与侧阀体内表面贴合，所述阀座支承左端内表面与球体表面接触；所述阀座支承和球体之间包括密封圈A，所述阀座支承上设有与密封圈A适配的密封槽；所述阀座支承上还设有刮刀，刮刀嵌装在阀座支承左端的内表面上；所述阀座支承与侧阀体之间还包括螺旋弹簧，侧阀体上设有与螺旋弹簧适配的盲孔，所述盲孔设置在第一台阶的竖直面上；所述阀座支承右部内表面还设有工装 卡槽，所述工装卡槽为环状卡槽。
优选的，所述密封圈A的截面为三角形。
优选的，所述刮刀位于密封槽下方，刮刀与阀座支承过盈配合。
优选的，所述阀座支承和侧阀体接触形成一个密封腔，所述密封腔位于第二台阶处，密封腔内设有密封圈B。
优选的，所述密封圈B为O形密封圈。
本实用新型设计有工艺卡槽结构，在阀门装配完成到安装到管道系统的过程中，阀座与球体的密封面会堆积杂质，只靠介质压力很难完全清洗干净，本实用新型提供的结构可通过工装卡住工装卡槽，带动阀座沿轴线、远离球体的方向平移，从而使阀座密封面和球体密封面分离，再通过气体或液体清洗密封面，可完全清除杂质，避免密封面擦伤。
附图说明
图1为本实用新型结构示意图。
图中：1-球体、2-密封圈A、3-密封槽、4-阀座支承、5-螺旋弹簧、6-工装卡槽、7-盲孔、8-第一台阶、9-第二台阶、10-侧阀体、11-密封腔、12-密封圈B、13-刮刀。
具体实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图，对本实用新型进行进一步详细说明。
如图1所示，一种防擦伤可清洗球阀阀座结构，包括球体1、阀座支承4和侧阀体10，所述侧阀体10内表面为台阶状，包括第一台阶8和第二台阶9；所述阀座支承4外圆与侧阀体10内表面贴合，所述阀座支承4左端内表面与球体1表面接触；所述阀座支承4和球体1之间包括密封圈A2，所述阀座支 承4上设有与密封圈A2适配的密封槽3；所述阀座支承4上还设有刮刀13，刮刀13嵌装在阀座支承4左端的内表面上；所述阀座支承4与侧阀体10之间还包括螺旋弹簧5，侧阀体10上设有与螺旋弹簧5适配的盲孔7，所述盲孔7设置在第一台阶8的竖直面上；所述阀座支承4右部内表面还设有工装卡槽6，所述工装卡槽6为环状卡槽。
优选的，所述密封圈A2的截面为三角形。所述刮刀13位于密封槽3下方，刮刀13与阀座支承4过盈配合。所述阀座支承4和侧阀体10接触形成一个密封腔11，所述密封腔11位于第二台阶9处，密封腔11内设有密封圈B12。所述密封圈B12为O形密封圈。
当然，本实用新型还可有其它多种实施例，在不背离本实用新型精神及其实质的情况下，熟悉本领域的技术人员可根据本实用新型作出各种相应的改变和变形，但这些相应的改变和变形都应属于本实用新型所附的权利要求的保护范围。
