专注通风管道加工·排烟罩

　　Shandong ventilation duct processing air flow control valve can be used in subway ventilation, air conditioning system fire prevention and smoke exhaust, valve with fire automatic alarm equipment and gas fire extinguishing system linkage control function.

　　每台全自动风量调节阀有两个独立电动控制信号，分别由EMCS、气消系统进行监控，控制信号均为DC24V±10%信号。风量调节阀在安装时一定要做好以上几个注意事项，只有这样在火灾发生时才能发挥它的特性，保护人身和财产。

　　Each automatic air volume control valve has two independent electric control signals, which are monitored by EMCS and gas elimination system respectively, and the control signals are DC24V + 10% signals. In the installation of air flow control valve, we must do a good job of the above considerations, only in this way, when the fire can take place in its characteristics, protect personal and property safety.

　　1.排烟防火阀选用主要控制参数为规格等。

　　1. smoke exhaust fire valve, the main control parameters for specifications.

　　2.排烟防火阀叶片应为钢板，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。

　　2., smoke exhaust valve blade should be steel plate, the thickness of 2~6mm, the valve is non combustible material, the rotating components should be corrosion-resistant metal materials, and flexible rotation. The shell thickness of the valve shall not be less than 2mm. Easy to melt components shall comply with fire department approval standards.

　　3.选用排烟防火阀时应注意阀门的功能，如常开还是常闭、自动关闭开启、手动关闭开启、手动复位、讯号输出、远距离控制等要求。

　　3. selection of smoke fire valve should pay attention to the function of the valve, normally open or normally closed, automatic shutdown, open, manual closed, open, manual reset, signal output, remote control requirements.

　　4.排烟防火阀适用于通风、空调或排烟系统的管道上.

　　4. smoke dampers are suitable for ventilation, air conditioning, or smoke extraction systems

　　5.排烟防火阀适用于通风空调系统，除公共建筑的厨房排油烟系统用防火阀，动作温度为150℃外，一般通风空调系统用排烟防火阀动作温度为70℃。

　　5. smoke fire dampers for ventilation and air conditioning system, in addition to public buildings kitchen smoke exhaust system with fire dampers, action temperature of 150 degrees outside, general ventilation and air conditioning system with smoke exhaust fire valve action temperature of 70 degrees.

　　6.排烟防火阀若与风机联动的应选用带双微动开关装置。

　　6. if the smoke damper and the fan linkage should be selected with dual micro switch device.
