Abstract

本实用新型的暖气包防泄水排气嘴属采暖系统 小附件，具有明显的节能效果，其外形尺寸大小与手 动旋塞式放气阀相差不多，关键是在阀腔内部依次放 置了弹簧、钢球和密封圈，用阀塞旋紧压紧而成，克服 了采暖散热器的跑水现象和私自用水现象的发生，本 实用新型的暖气包防泄水排水嘴结构简单、体积小 巧、便于安装、工作安全可靠、造价低廉，适宜推广使 用。

Description

本实用新型的暖气包防泄水排气嘴属暖气包放气阀的改进新型。
原暖气系统的排气阀有跑水和人为用水现象发生，专利申请号为91203076.3的自动阻水排气阀是通过阀体腔内的小球对气流和水流的不同作用而分别开启或堵塞阀口，从而起到水暖系统散热器的自动阻水排气作用，另有人设想浮球杠杆式自动排期嘴，据初步分析，这套机构将较为复杂，安装维修难度大，工作稳定性差，难以推广使用。
本实用新型的目的是提出一种用手工方法完成散热器排气阻水功能的暖气包防泄水排气嘴。
本实用新型的设计思想是在放气阀腔内设置弹簧、钢球、密封圈和带丝扣、带气眼孔的阀塞，用人工将一钢性杆从阀塞气眼孔穿进用人工顶回钢球、弹簧，从而完成放气任务，抽回钢性杆，钢球在弹簧作用下，又将气眼孔堵死，防止排水。
图1是本实用新型的暖气包防泄水排气嘴的结构简图。
（1）阀体；（2）弹簧；（3）钢球；（4）密封圈；（5）阀塞。
本实用新型的暖气包防泄水排气嘴，外形尺寸大小与原手动旋塞式排气嘴相仿，但其内部结构却截然不同，这种防泄水排气嘴靠尾部的螺纹与暖气包连接，排气时，只要将排气顶杆顶入阀塞（5）前面中央的气眼孔内，排气顶杆推动钢球（3）向后移动，同时压缩后面弹簧（2），这时暖气包内的气体与外部大气沟通，由于内、外压力差的作用，积存气体就排入大气，气体排完后，随即有水溢出，这时将顶杆抽出，钢球（3）在弹簧（2）弹力的作用下，被推进到带有锥孔的橡胶密封圈（4）内，在弹簧力和暖气包内部压力的作用下，钢球被压得很紧，这样就可以止住暖气水的外溢，从而达到了排气和防排水的功能。
该产品由五个部件组成，结构简单，体积小巧，安装拆卸方便，工作安全可靠，造价低廉。
