Abstract

本实用新型涉及一种带防火阀式排气管,包括排气道、、导向弯、阀片、易熔片,其特征是:带防火阀式排气管上进气口内有导向弯,导向弯上方出气口边沿有一组压缩弹簧装置,阀片下端的轴套与一组压缩弹簧中的固定轴连接,支架上的易熔片钩住阀片,本实用新型的优点是当排气道内温度达到摄氏70度时,易熔片熔断,阀片盖住导向弯上方的出气口,火焰无法窜进室内造成火灾。

Description

带防火阀式排气管
技术领域
本实用新型涉及一种住宅建筑内集中排气用的带防火阀式排气管。
背景技术
目前,市埸上住宅建筑用的集中排气管内没有防火阀,当排气管内有火焰时,容易窜进室内,造成火灾。
实用新型内容
本实用新型的目的是当住宅建筑内排气管内温度达到摄氏70度时,防火阀关闭,排气道内焰火不会窜进室内造成火灾。
本实用新型的技术方案是设计一种带防火阀式排气管,包括排气道、导向弯、阀片、易熔片,其特征是:带防火阀式排气管上的进气口内有导向弯,导向弯上方出气口边沿有一组压缩弹簧装置,阀片下端的轴套与一组压缩弹簧内的固定轴连接,支架上的易熔片钩住阀片。
本实用新型的优点是当室内往外排气时,烟气有导向弯向上排放,当排气道内温度达到摄氏70度时,易熔片熔断,阀片盖住出气口,火焰无法窜进室内。
附图说明
附图为本实用新型的结构剖面示意图;
附图中数码分别表示为:排气道1、进气口2、导向弯3、出气口4、一组压缩弹簧5、阀片6、支架7、易熔片8。
具体实施方式
实现本实用新型方式是带防火阀式排气管上进气口2,连接室内排气装置,当往外排气时,烟气通过导向弯3上方出气口4进入排气道1,当排气道1内温度达到摄氏70度时,支架7上的易熔片8熔断,阀片6脱钩,一组压缩弹簧5复位,压迫阀片6盖住出气口4,火焰无法窜进室内造成火灾。
