Abstract

本实用新型涉及一种蓄电池用单向阀密封塞,它 包括上下盖,弹簧和密封塞,经过组装,使该塞在使用 时可以随需要而进行工作,即在需密封时,弹簧可以 压住密封塞,而在需要放出部分气体减小电池内压力 时,气体会将密封塞顶起而排出,直到压力降低后,密 封塞重新由弹簧压紧。

Description

本实用新型涉及的是一种蓄是池用单向阀密封塞。
人们知道,蓄电池在工作过程中,经常会出现水气外溢或气压升高等问题,于是出现了许多解决方案,试图一方面密封电池,使电池中的水气不外溢,另一方面又能使电池在其内压达到一定程度时排出部分气体,以防止电池爆裂损坏。然而,目前还未见到理想的技术解决方案和可靠的解决形式。
本实用新型的目的,就是提供一种可靠的蓄电池用单向阀密封塞,它既可以达到减少外加水的工作或根本不加水,又可以达到免维护或少维护的作用,从而克服了上述缺陷。
为了实现本实用新型的上述目的,具体的实施形式是,采用的单向阀密封塞包括上、下盖,均可为塑料制成,在两盖之间装有由弹性材料制成的密封塞,如橡皮塞,和弹簧。其具体工作过程是,弹簧对橡皮塞施加一定压力,其压力可根据需要来选取不同的弹簧,使橡皮塞堵住下盖的出气孔,使电池成密封状态以阻止水气外溢,而当电池内部气压过大时,气体会首先将橡皮塞顶起,使少量的气体从排气孔排出,从而降低电池内压,以防止电池爆裂损坏,在电池内压减小时,弹簧又重新压回橡皮塞堵住排气孔,使电池又为密封状态。这样既可以减少充电中或搁置期间水的损失,又不至因内压过高而致电池爆裂。
图1是各部件组装示意图,它示出了按本实用新型制造出的电池用单向阀密封塞。
下面结合附图对本实用新型作进一步详细的描述。
在图1中,图1a是组装在一起的单向阀密封塞的结构图。图1b是上盖,图1c是弹簧,图1d是圆台形橡皮塞,图1e是下盖。从图1中可以清楚地看到,弹簧是放置在橡皮塞的上方,而两者均放置在上下装置之间,并通过上下盖上的螺纹加以固定。
从上述的描述中,可以确信,本实用新型设计出的单向阀密封塞完全达到了上述的目的,并具有安全可靠,保持电池中水气不外溢等优异特性,其结构简单,便于推广使用。
