Abstract

本实用新型提供了一种自闭式节水阀。该阀由 阀体、密封球和控制杆及定位销连接组成,其结构新 颖、制作简易、节省水源,使用寿命长,可广泛地在实 际生活中尤其是公共用水场所推广应用,具有较好的 使用价值,系一种新型的自闭式节水阀。

Description

本实用新型属于机械工程技术领域中的一种阀,具体地系一种球状闭合件的自闭式水阀。
通常的水阀多是由阀体和带螺旋联杆的锥形阀芯或闸板式阀芯连接组成。它通过旋转联杆调节阀芯与阀体内座孔的动配合,来实现阀门的开启和关闭,但由于现有水阀的螺杆与阀体的连接螺纹和密封易于损坏,使用寿命短,且开关繁琐,尤其用于公共用水场所常出现长流水问题,严重浪费水资源。
本实用新型之目的是提供一种改进的水阀,实现其结构新颖、制造简易、开关方便、使用寿命长,用后水阀自行关闭,节省水源。
本实用新型是这样实现的:采用密封球为闭合元件装置于竖式的阀体内并与阀体中部的球缺状凹孔形成紧密的动配合连接,在阀体下部体壁上横向插连控制杆,控制杆中部制有凸台触连密封球,组成为自闭式水阀。该阀的控制杆以阀体内壁的盲孔为支点,当托动控制杆沿阀体上的导槽向上移动时,控制杆的中凸部顶起密封球脱离配合的球缺孔,将阀开启。用毕后,手离控制杆,控制杆沿阀体的导槽自动下落,密封球随之回位将阀体内的通孔封闭,阀便自行关闭。
本实用新型的优点是结构新颖,设计合理、制造工艺简易,使用方便,应用寿命长。因该阀为常闭式,用后自行关闭,节省水资源。它可广泛地在实际生活中尤其是公共用水场所等推广应用,具有较好的实用价值,是一种新型的自闭式节水阀。
下面结合附图对本实用新型作进一步详细描述。
图1是本实用新型具体结构的剖视图。
如附图所示,本实用新型由阀体(1)、密封球(2)和控制杆(3)及定位销(4)所组成。阀体(1)为竖式阀体,密封球(2)为阀芯。密封球(2)装置于阀体(1)的上孔口内与阀体的球缺状凹孔成紧密的动配合连接。控制杆(3)通过阀体(1)的导槽横向插连位于密封球(2)下部阀体(1)上的盲孔,并在控制杆(3)上装有定位销(4)将控制杆(3)与阀体(1)定位连接。控制杆(3)杆体中部制有凸台,凸台的顶端触连密封球(2),控制阀门的开启或关闭。
