Abstract

本实用新型涉及一种蝶阀蝶板锁紧螺丝的防松动固定装置,包括筒体,所述筒体底部设有一孔,筒体开口端圆周上设有内折边和外折边。本实用新型结构简单、使用方便、生产制造容易,制造成本低。

Description

蝶阀蝶板锁紧螺丝的防松动固定装置
技术领域
本实用新型涉及蝶阀制造技术领域,尤其是涉及一种蝶阀蝶板锁紧螺丝的防松动固定装置。
背景技术
现有蝶阀和蝶板压环上的连接使用常规内六角螺钉,在螺钉下面加上弹性垫圈,此结构能够在振动较小的工况下防止螺钉松动。在一些特殊工况下,如流体冲刷蝶板剧烈,阀门的振动较大,抽气蝶阀关闭速度比较快等,此结构也会产生松动,对阀门的性能产生一定的影响。
实用新型内容
本实用新型针对上述缺陷,目的在于提供结构简单、使用方便、生产制造成本低的蝶阀蝶板锁紧螺丝的防松动固定装置。
为此本实用新型采用的技术方案是:本实用新型包括筒体,所述筒体底部设有一孔,筒体开口端圆周上设有内折边和外折边。
所述内折边和外折边数量各位两个,并均匀分布。 
本实用新型的优点是:本实用新型具有结构简单、使用方便、生产制造成本低的特点。
附图说明
图1为本实用新型的结构示意图。
图2为图1的俯视图。
图3为图1的左视图。
图4为本实用新型使用安装示意图。
图中1为筒体、2为内折边、3为外折边、4为螺钉、5为蝶板、6为蝶板压环。
具体实施方式
本实用新型包括筒体1,所述筒体底部设有一孔,筒体开口端圆周上设有两个内折边2和外折边3,且对称均匀分布,将螺钉4穿过筒体底部孔与蝶板5连接,待螺钉4拧紧后,将内折边2向内折,卡紧螺钉4,将外折边3向外折,卡紧蝶板压环6。
