Description

密封构件
技术领域:
本实用新型涉及一种密封构件,尤其涉及一种离心泵上轴端的密封构件。
背景技术:
随着工业化的发展,机械设备尤其是离心泵轴端密封问题得到的长足的进步。一些传统的密封方式如填料式密封方式都为波纹管式密封方式所替代。虽然密封方式的发展扩大了适用范围,能够用于高温、低温、强腐蚀性等工作情况,但是这些密封方式都存在着密封面磨损的问题,尤其是成本较高的波纹管式密封方式,密封面一旦磨损就需整体更换,造成了较大的浪费。
发明内容:
本实用新型的目的就是为了解决上述问题,而提出了一种新型的密封结构。本实用新型涉及巧妙,能够在设备转动时开启,停机时闭合,保证设备在工作期间密封的可靠性。
本实用新型提供的技术方案是:
密封构件,由密封腔盖、静环等组成。轴套一端有螺纹,另一端平均开有离心孔;轴套与密封腔盖之间形成间隙A,在轴套的离心孔的两侧装有动环与静环,动环与静环形成可变间隙B,在动环上装有弹性元件,离心孔内装有离心柱头。所述轴套的螺纹也可以是螺旋槽且旋向与轴的旋转方向相反。
所述动环内表面上有与离心柱头接触的环形斜台或斜槽。
弹性元件为弹簧。
本实用新型结构简单,易于实现;大大延长了机械设备的使用寿命,而且密封可靠,可以广泛的应用于各种旋转类设备中。
附图说明
图1是本实用新型的结构示意图
1轴套2密封腔盖3弹簧4动环5离心柱头6静环7轴8螺纹9离心孔图中A为轴套与密封腔盖之间形成的间隙
图中B为动环与静环形成的可变间隙
具体实施方式
在轴套的左端开有一定长度的螺纹,螺纹部分与密封腔盖之间形成间隙A,螺纹的旋向与轴的旋转方向相反,在轴套的右端开有若干均匀分布的离心孔,在离心孔内装有离心柱头。
当设备运转时,轴套上的螺纹将介质密封住,此时由于离心力的作用,离心柱头将动环向左推开,使动环和静环不再摩擦。
当停机时,离心柱头失去离心力,在弹簧的作用下,动环被推向右方,于是动环与静环闭合,防止液体介质泄露。
最后应当说明的是:以上实施例仅用以说明本实用新型的技术方案而非对其限制;尽管参照较佳实施例对本实用新型进行了详细的说明,所属领域的普通技术人员应当理解:依然可以对本实用新型的具体实施方式进行修改或者对部分技术特征进行等同替换;而不脱离本实用新型技术方案的精神,其均应涵盖在本实用新型请求保护的技术方案范围当中。
