Description

封闭式水箱气阀
本实用新型涉及一种封闭式水箱气阀,尤其用于热水器上。
对于封闭式水箱,由于箱内空气的影响,水箱充满成为一难题;即使设法充满,由于负压的作用,使水的排出也增加了困难,水箱中有水而无法使用。
本实用新型的目的在于为封闭式水箱提供一种气阀,在封闭式水箱上使用该气阀,可很方便地对水箱充满水或从水箱中随时取水。
本实用新型所述的封闭式水箱气阀,阀体两端相通,其阀体空腔中设有一水浮子,水浮子的形状与气阀的出口相适应。
水箱中的水不满时,水浮子沉在下,水箱中气体与大气相通,不存在气体被挤压或腔内存在负压的问题,充水、取水都十分方便。当充满水时,腔中的气体被赶净,充满的水使水浮子浮起,水浮子将气阀的出口堵塞,水箱满水,充水结束。需要放水时,随着水的流出,水浮子在大气压和自身重量的作用下下沉,空气从气阀的出口进入水箱内,水箱内外气体相通,水箱中的水便可以很容易地放出。
为了增强水浮子的密封性,将水浮子设计为具有弹性的水浮子。在挤压时,弹性水浮子变形,改善密封性能。
下面结合附图及实施例对本实用新型作进一步的说明。
图1、本实用新型在应用中的一结构示意图,亦为实施例。
图中:1阀体、2出口、3空腔、4高分子弹性材料水浮子、5进口、6水箱。
如图所示,本实用新型所述的封闭式水箱气阀,阀体两端相通,阀体1空腔3中设有一高分子弹性材料水浮子4,水浮子4的形状与气阀的出口2相适应。
本实用新型结构简单,科学合理。在封闭式水箱上使用该气阀,可很方便地对水箱充满水或从水箱中随时取水。本实用新型特别适用于封闭式热水器水箱上,给热水器的使用带来较大方便。
