通风和空调体系中3c排烟防火阀设置的若干问题 ​

发布日期:2018-06-22 作者:德州金航 点击:

通风、空气调节体系中3c排烟防火阀的设置和选用,是暖通专业规划中量大面广的作业内容。我国现行的有关规划标准,都对防火阀的设置部位作了规则。可是,由于这些标准公布实施的时刻不同,加上实践工程的千差万别,以及对条文的了解方面发生的差异,关于防火阀的设置及选用常常引起争议。本文经过剖析讨论,期望能够添加共同,削减不合,使实践工程中3c排烟防火阀浙江11选5走势图的设置和选用更加合理。

用于通风、空气调节体系中的防火阀有两种:一种可称为一般防火阀,其首要功用是:70℃温度熔断器主动封闭(防火),能够输出封闭电信号;另一种为防烟防火阀,靠烟感器操控动作,用电信号经过电磁铁封闭(防烟),还可70℃温度熔断器主动封闭(防火),手动封闭,手动复位,输出封闭电信号。

《建规》第9.3.7条条文阐明,是讲进入出产厂房的水平或笔直风管设防火阀,但其附图9.3.7中并未呈现防火阀;图9.3.10-a为送回风管穿过机房隔墙和楼板的防火阀安置示意图,但该图却没有在穿过机房隔墙和楼板处的送回风管上设防火阀,只是在送、回风水平管与笔直总管交接处设了防火阀,与图9.3.10-c类似,何况该图中送风机房2中,有两个未标示阀门,颇令人费解。从图例上看好象是防火阀,但同一送风机房内的管道是没有必要设防火阀的。至于9.3.10-b中,将送排风管上的防火阀标示颠倒(7应为送风管上的防火阀,8应为送风管上的防火阀),且送风口浙江11选5走势图箭头标错方向,则完全是笔误,实属不应。
