Abstract

本实用新型是一种暖气自动排气阀。在底座上,有一浮子室、室内有浮子、利用气、液对浮子的作用将排气阀打开或关闭,达到自动排气的目的。

Description

本实用新型是一种暖气自动排气阀。
目前通用的暖气排气阀是一种金属针形阀,由人操纵排气,不能自动开关。
本实用新型的目的在于设计一种浮子式暖气自动排气阀。利用气液对浮子的作用,将排气阀打开或关闭达到自动排气的目的。
结合附图1,本实用新型是这样实现的。在底座7上浮子室内有一空心浮子6,顶端排气口上有工字型阀杆1,中间套螺旋弹簧2和胶垫5。
底座与暖气片相连,排气阀与大气相通,可随时排气。当暖气片中的气体排净,水进入浮子室,将浮子逐渐浮起,浮起的浮子将顶部的排气阀杆弹簧压缩,阀杆向上移动,胶垫将排气口关闭,液体不能排出。如果浮子室气体增加,水被逐渐从浮子室排回暖气片,浮子则逐渐下降,阀杆在弹簧作用下,向下移动,排气口打开,实现排气。
