Abstract

本实用新型涉及一种适用于已有自来水阀门的 防漏阀。它主要由阀杆、阀盖、空心半球状的橡胶密 封圈、阀座和阀芯组成。其中阀盖与阀座之间的密封 是通过橡胶密封圈实现,橡胶密封圈被固定在阀盖和 阀座的内圆上,并与阀芯的连杆固定密封联接。阀门 打开时,水压使阀芯上移,水流出,关闭时,阀杆压在 阀座的进水腔上,使阀门关闭。优点是不漏水,维修 方便。

Description

本实用新型涉及一种防止漏水现象发生的阀门。它适用于各种普通已有的阀门,以防漏水。
CN90203167.8公开了一种“可避免跑水现象的水嘴”,其阀芯与阀座经过改进,关闭水流的阀口位于进水腔,当阀杆因滑丝失去控制开关的作用时,水嘴可自行关闭。从而不致产生跑水现象。
另外,已有的阀门均采用石棉垫圈压住进口腔防漏,随着使用时间的沿长,时而有漏水现象。维修时需关闭阀门才可修理。
本实用新型的任务是设计一种防漏阀,以达到开关自如,不漏水和维修方便的目的。
本防漏阀采用下述设计方案实现。
一种防漏阀,它主要由阀杆、阀盖、橡胶密封圈、阀座和阀芯组成。其结构特征在于阀杆与阀盖螺纹配合,在阀杆的下端开有孔,并与阀芯的连杆间隙配合。连杆上另有固定橡胶密封圈,阀心位于进水腔上,阀盖与阀座螺纹联接。
所述橡胶密封圈为空心半球状。
附图为本防漏阀整体结构剖视图,其图中各称号为:
1、阀杆 2、阀盖 3、橡胶密封圈 4、阀座 5、阀芯。
附图给出了本防漏阀的一个具体实施例。
阀杆1为铸铜件,并与阀盖2螺纹密封联接,阀盖2为铸铁件。橡胶密封圈3通过垫片和螺帽被固定密封在阀芯5的连杆上,橡胶密封圈3的外沿被阀盖2的内园和阀座4内园挤压密封,即阀盖2与阀座4之间密封是通过空心半球状的橡胶密封圈3来实现的。当打开阀门时,在自来水的压力作用下,使阀芯5上移,并带动橡胶密封圈3同时上移,使水流出;当关闭阀开时,阀杆1压在阀芯5的进水腔上,使之断水(参见附图)。
本阀的优点在于:不漏水、维修方便。
