专注通风管道加工·排烟罩

　　First, smoke smoke damper strong air tightness, mainly reflected in the following four aspects:

　　1、执行机构驱动灵活。反馈、联锁信号准确。

　　1, actuators flexible. The feedback and interlocking signals are accurate.

　　2、漏风量低，气密性能好。

　　2 、 the air leakage is low, and the air tightness is good.

　　3、电动开启消耗电流小。

　　3 、 electric opening consumes little current.

　　4、防腐性能强，使用寿命长。

　　4, corrosion resistance, long service life.

　　二、在装修排烟防火阀时可以参照这些要点进行检查，可以减少后期的损害，主要有以下五点：

　　Two, in the decoration smoke smoke fire valve can refer to these points for inspection, can reduce the damage later, mainly has the following five points:

　　1、排烟防火阀的熔断片应装在朝向火灾危险性较大的一侧。

　　1. The fuse shall be installed on the side of the fire danger.

　　2、排烟防火阀可与通风机、排烟风机联锁，阀门的操作机构一侧应有不小于200mm的净空间以利检修。

　　2, smoke fire dampers can be ventilation, smoke exhaust fan interlock, the valve side of the operating mechanism should be less than 200mm of the net space, in order to facilitate maintenance.

　　3、排烟防火阀应单独设支吊架，以防止发生火灾时管道变形影响其性能。

　　3 smoke exhaust fire valve shall be provided with separate hangers to prevent pipe deformation during fire and affect its performance.

　　4、安装排烟防火阀阀门前必须检查阀门的操作机构是否完好，动作是否灵活有效。

　　4, the installation of smoke fire valve, valve must check whether the operation of the valve is intact, the action is flexible and effective.

　　5、排烟防火阀应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。

　　5, smoke fire pipe valve should be installed in the wall or floor close to the wind in the fire valve fire partition walls on both sides of the distance from the wall surface should be no more than 200mm, the pipeline fire valve on both sides of the range of 2.0m and the adiabatic material should use non combustible materials.
