专注通风管道加工·排烟罩

　　When the inner core tube is installed, it is fully unfolded by pushing screw. The outer wall of the core tube is tightly connected with the inner wall of the trachea. The opening at the end of the core tube is closed by a liner, forming a second sealing surface.

　　所述橡胶密封圈与所述风管管壁被压缩形成第三密封面，从而可靠地满足所述芯管连接的密封要求。

　　The rubber sealing ring and the air pipe wall are compressed to form a third sealing surface, thereby reliably meeting the sealing requirements of the core pipe connection.

　　内芯管用于风管连接的运行

　　Inner core tube for air duct connection operation

　　安装前将“0”形橡胶密封圈张紧力嵌入“v”形槽内的芯管，芯管两端开口处于shiplap状态，直径较窄。使它可以很容易地把保持连接到管口,安装时在推动螺杆芯直径膨胀,当核心管两端对齐,完成内部扩张业务,与心墙风管壁紧密,然后用自攻螺丝或铆钉核心管和管周向固定安装完成。

　　Before installation, the tension force of the "0" rubber sealing ring is embedded in the core tube of the "v" groove. The opening of both ends of the core tube is in shiplap state, and the diameter of the core tube is narrow. It can be easily maintained to the nozzle, and when installed, the diameter of the screw core expands. When the two ends of the core tube are aligned, the internal expansion business is completed, and the core wall air duct wall is tightly connected. Then the core tube and the tube are fixed by tapping screw or rivet.

　　工作区域新风预处理风机-为厨房工作区域(人员工作岗位)提供经过预处理的新风。济南烟机安装人员提供约20%的排烟风量，排烟风机排烟炊事烹调区提供烟机油和煤气。

　　Fresh Air Pretreatment Fan for Working Area - Provide pre-treated fresh air for kitchen working area (staff position). Jinan smoke machine installation personnel provide about 20% of the smoke exhaust air, smoke exhaust fan to the cooking area to provide smoke engine oil and gas.

　　厨房排烟风机排烟罩除消防排烟风机管外，考虑到厨房工作温度过高的原因。其他风机管道建议安装150℃消防阀(与平时普通风机管道设备70℃略有不同)。当火灾排烟风机发生作用时，必须关闭所有其他风机(消防送风从窗外、门缝等处进入)。开启“排烟风机”时，应同时开启“通风柜补充风机”和“工作区域新风预处理风机”(联动)。

　　The smoke hood of kitchen exhaust fan takes into account the high working temperature of kitchen besides the fire exhaust fan tube. Other fan pipelines are recommended to install fire valves at 150 C (slightly different from normal fan pipeline equipment at 70 C). When the fire exhaust fan works, all other fans must be shut down (fire supply air enters from windows, door cracks, etc.). When opening the "smoke exhaust fan", the "supplementary fan of the ventilator" and the "fresh air pre-treatment fan of the working area" (linkage) should be opened at the same time.

　　厨房排烟罩排烟管末端设置排烟阀，排烟风机排烟罩与排烟管连接处设置排烟防火阀。需要注意的是，排气阀与排气阀是完全不同的设备功能。排烟阀平时通常是关闭的。如遇火灾打开时，将与报警主机连接。开启条件是自动报警系统将发生火灾(探测器报警)，火灾报警主机将处于自动状态。排烟消防阀通常是开启的，火灾也处于开启状态，但当排烟温度达到280℃时，排烟消防阀自动关闭，联动风机已开启停止运行。

　　A smoke exhaust valve is arranged at the end of the smoke exhaust pipe of the kitchen smoke hood, and a smoke exhaust fire valve is arranged at the connection between the smoke exhaust hood of the exhaust fan and the smoke exhaust pipe. It should be noted that the exhaust valve and the exhaust valve are completely different equipment functions. The exhaust valve is usually closed. In case of fire, it will be connected with the alarm host. The opening condition is that the automatic alarm system will have a fire (detector alarm), and the main fire alarm machine will be in an automatic state. The smoke exhaust fire valve is usually open, and the fire is also open. But when the smoke exhaust temperature reaches 280 C, the smoke exhaust fire valve closes automatically, and the linkage fan has been opened and stopped running.
