Abstract

本实用新型公开了一种带有填料函的蝶阀,它的阀体(1)包括壳体(2),在壳体(2)内插有阀杆(3),阀杆(3)的上部与壳体(2)之间设有间隙,在间隙内设有填料(4),所述的填料(4)的下部设有保护组合件,保护组合件位于间隙内,保护组合件套在阀杆(3)上。本实用新型不但可以有效地防止填料磨损老化,减轻介质的冲蚀,而且提高蝶阀的使用寿命。

Description

一种带有填料函的蝶阀
技术领域
本实用新型涉及一种带有填料函的蝶阀。
背景技术
填料装入填料函后,经压盖对其施加轴向压力,由于填料的塑性变形,产生径向力,并与阀杆紧密接触,但这种接触往往并不均匀,加之在使用过程中,渗透性强的介质的影响和填料自身的老化,使填料与阀杆间产生泄漏。
发明内容
本实用新型提供了一种带有填料函的蝶阀,它不但可以有效地防止填料磨损老化,减轻介质的冲蚀,而且提高蝶阀的使用寿命。
本实用新型采用了以下技术方案:一种带有填料函的蝶阀,它的阀体包括壳体,在壳体内插有阀杆,阀杆的上部与壳体之间设有间隙,在间隙内设有填料,其特征所述的填料的下部设有保护组合件,保护组合件位于间隙内,保护组合件套在阀杆上。
所述的保护组合件包括上金属环、下金属环和碟形弹簧组合,碟形弹簧组合位于上金属环和下金属环之间。所述的碟形弹簧组合包括三个碟形弹簧,三个碟形弹簧相互叠加后套在阀杆上。
本实用新型具有以下有益效果:本实用新型在填料的下部设有保护组合件,保护组合件包括上金属环、下金属环和碟形弹簧组合,碟形弹簧组合位于上金属环和下金属环之间,碟形弹簧组合包括三个碟形弹簧,碟形弹簧套在阀杆上,这样上、下两只金属保护环能有效耐介质冲蚀,中间采用3只碟形弹簧叠加能在较小的轴向距离上提供较大的螺栓预紧力,保护填料不受过分压力从而导致填料不会在短期内即发生严重磨损而报废,减轻介质的冲蚀,提高蝶阀的使用寿命,缩短维修期限。
附图说明
图1为本实用新型的结构示意图
具体实施方式
在图1和图2中,本实用新型为一种带有填料函的蝶阀,它的阀体1包括壳体2,在壳体2内插有阀杆3,阀杆3的上部与壳体2之间设有间隙,在间隙内设有填料4,其特征所述的填料4的下部设有保护组合件,保护组合件位于间隙内,保护组合件套在阀杆3上,保护组合件包括上金属环5、下金属环7和碟形弹簧组合,碟形弹簧组合位于上金属环5和下金属环7之间,碟形弹簧组合包括三个碟形弹簧6,三个碟形弹簧6相互叠加后套在阀杆3上。
