德州德祥正压送风口集研发,生产,销售于一体的专业厂家,正压送风口以高质量的售后赢得市场,产品畅销全国各地,深受广大用户青睐,质量可靠、品种齐全、服务保证,欢迎咨询!
通风、空调或排烟系统的管道上,常见正压送风口设备,那么它是怎样工作的呢?下面德祥小编具体为你介绍:安装风口前必面临如何选型问题,如常开还是常闭、手动复位、讯号输出、远距离控制等要求。选型详解如下:
 
正压送风口厂家
正压送风口联动应选用带双微动开关装置。叶片应为钢板,厚度为2~6mm,阀体为不燃材料制作,转动部件应采用耐腐蚀的金属材料,并转动灵活。阀门的外壳厚度不得小于2mm。易融部件应符合消防部门的认可标准。且安装正压送风口联锁时一定要留空间,以便以后维护检修。安装前必须检查阀门的操作机构是否完好,动作是否灵活有效。
正压送风口通常安装在紧靠墙或楼板的风管管段中,防火分区隔墙两侧的防火阀距墙表面不应大于200mm,防火阀两侧各2.0m范围内的管道及其绝热材料应采用不燃材料。应单独设支吊架,以防止发生火灾时管道变形影响其性能。熔断片应装在朝向火灾危险性较大的一侧。 
 
正压送风口工作原理
如安装在通风、空调系统的送、回风管路上,平时呈开启状态,管道内气体温度达到70℃时即自行关闭,并在一定时间内能满足耐火稳定性和耐火完整性要求,起隔烟阻火作用。
如安装在排烟系统管道上或排烟风机的吸入口处,平时呈关闭状态,当火灾发生时,通过火灾报警信号手动或自动开启阀门,根据系统功能配合排烟,当管道内烟气温度达到并能在一定时间内满足耐火稳定性和耐火完整性要求,起隔烟阻火作用。
