Abstract

一种水阀,包括阀体、阀芯、阀杆、阀盖,阀杆活接于阀盖的上端,其中阀盖上阀盖与阀杆活接处的下面为一台阶,台阶上设有用于密封阀杆的密封圈,密封圈呈台阶状,密封圈的下面和内侧面均设有槽。本实用新型与已有技术相比能有效地将阀杆密封,防止了水从阀杆与阀盖间的活接处泄漏出去。

Description

一种水阀
本实用新型涉及一种水阀。
现有的水阀一般由阀体、阀芯、阀杆、阀盖构成,为了防止水从阀盖与阀杆间的空隙泄漏出去,在阀杆与阀盖间还设有密封垫圈,此种水阀由于仅靠密封垫圈固有的压在阀杆上的弹力将阀杆密封,在使用过程中,阀杆与密封垫圈不断摩擦,使密封垫圈不断磨损,当密封垫圈被磨损到其弹力不足以将阀杆密封时,水就沿阀杆泄漏出去,此外,若水阀装配不当时,也会使水沿阀杆泄漏出去。
本实用新型的发明目的在于提供一种装配容易的、水不易沿阀杆泄漏出去的水阀。
本实用新型是这样实现的,包括阀体、阀芯、阀杆、阀盖,阀杆活接于阀盖的上端,其中阀盖上阀盖与阀杆活接处的下面为一台阶,台阶上设有用于密封阀杆的密封圈,密封圈呈台阶状,密封圈的下面和内侧面均设有槽。
本实用新型与已有技术相比,由于采用了带有槽的密封圈,当阀盖内充满水时,水压使密封圈下面的槽扩大,密封圈往内扩张,将阀杆紧密密封,从而有效地防止了水从阀盖与阀杆的接合处泄漏出去。
图1为本实用新型的构造示意图;
图2为本实用新型使用时密封圈变形的示意图。
现接合附图和实施例对本实用新型作进一步详细描述:
如图1所示,本实用新型主要由阀体1、阀芯2、阀杆3、阀盖4构成,阀杆3活接于阀盖4的上端,其中阀盖4上阀盖4与阀杆3活接处的下面为一台阶5,台阶5上设有用于密封阀杆3的密封圈6,密封圈6呈台阶状,密封圈6的下面和内侧面均设有槽8。使用时,打开阀门,一部分的水沿阀芯通道7进入阀盖4,在水压的作用下,密封圈6往内扩张,将阀杆3紧密密封。
