Description

可调节轴孔密封填料结构
技术领域
本发明涉及蝶阀技术领域，尤其涉及一种可调节轴孔密封填料结构。
背景技术
阀体轴孔是密封的重要部位，如果密封不好的话，则会发生严重的漏液现象，现有技术中的阀门上轴孔主要采用填料函的结构，这种填料结构长时间使用情况下会发生磨损，由于填料不能够调节，所以磨损越大，泄露就越明显。
发明内容
本发明的主要目的就是针对上述问题，提供一种可调节轴孔密封填料结构，防止外漏。
本发明为实现上述目的，采用以下技术方案：一种可调节轴孔密封填料结构，其特征在于：包括压板、压套、密封填料以及压紧螺栓；所述密封填料安装在阀轴与阀体之间的轴孔内，所述压套套在所述阀轴上并压在所述密封填料的上部，所述压板设置在所述压套上，所述压紧螺栓穿过所述压板外侧并与所述阀体的顶部螺纹连接。
优选地，所述压紧螺栓的顶部设有螺母，所述螺母与所述压板之间设有弹簧，弹簧套在所述压紧螺栓上。
优选地，所述压板与所述压套之间的接触面为倾斜面。
本发明的有益效果是:本装置通过压套压紧密封填料，通过压紧螺栓带动压板向下压紧压套，从而能够调节密封填料的紧实程度，当密封填料磨损后，通过调节压紧螺栓调节密封填料的，通过弹簧，可以使密封填料始终都有一个向下的力，从而提高密封填料的密封性能。
附图说明
图1为本发明的主视图。
具体实施方式
下面结合附图及较佳实施例详细说明本发明的具体实施方式。如图1所示，一种可调节轴孔密封填料结构，包括压板1、压套2、密封填料3以及压紧螺栓4；所述密封填料安装在阀轴5与阀体6之间的轴孔内，所述压套套在所述阀轴上并压在所述密封填料的上部，所述压板设置在所述压套上，所述压紧螺栓穿过所述压板外侧并与所述阀体的顶部螺纹连接。所述压紧螺栓的顶部设有螺母，所述螺母与所述压板之间设有弹簧7，弹簧套在所述压紧螺栓上。弹簧始终给压板一个向下的力，始终保持压套向下压紧密封填料，从而提高密封填料的密封性。在本发明中，所述压板与所述压套之间的接触面为倾斜面。
本装置通过压套压紧密封填料，通过压紧螺栓带动压板向下压紧压套，从而能够调节密封填料的紧实程度，当密封填料磨损后，通过调节压紧螺栓调节密封填料的，通过弹簧，可以使密封填料始终都有一个向下的力，从而提高密封填料的密封性能。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
