专注通风管道加工·排烟罩

　　Types of exhaust duct vents:

　　1. 活动百叶窗(双层数百页的风口通常用作送风口,也可以直接使用风机盘管,广泛应用的空调系统,也可以打开多用调节阀调节风量。单层百叶风口可上下风向调节，回风可配合风口过滤器使用，节流阀角度可调节，叶片之间有ABS塑料固定支架。清洗时可将固定过滤器从滑块上取下，清洗后推入滑块内继续使用。

　　1. Movable louvers (double hundreds of pages of air outlets are usually used as air outlets, but also can directly use fan coil units, widely used central air conditioning system, can also open multi-purpose control valves to regulate air volume. Single-layer louver tuyere can adjust the direction of upper and lower air, return air can cooperate with tuyere filter, throttle valve angle can be adjusted, ABS plastic fixed bracket between the blades. When cleaning, the fixed filter can be removed from the slider and pushed into the slider to continue using.

　　2、自闭百叶(自闭百叶式风口有正压空调室自动排风。通常依赖于风口百叶窗式的自重和自然下垂,隔离室内和室外空气交换,当室内空气压力大于室外空气的压力,空气会吹百叶窗和排气,相反,室内空气压力低于室外空气的压力,不能逆转的气流进入室内,风口有单向检查效果。

　　2. Self-closing louver (self-closing louver with positive pressure air conditioning room automatic exhaust air). Usually depends on the self-weight and natural sag of the tuyere louver, isolating the air exchange between indoor and outdoor. When the indoor air pressure is greater than the outdoor air pressure, the air will blow the louver and exhaust. On the contrary, the indoor air pressure is lower than the outdoor air pressure, and the irreversible air flow enters the room. The tuyere has one-way inspection effect.

　　3.风口控制阀(扩散器控制阀、卷帘风口控制阀)

　　3. Tuyere control valves (diffuser control valves, curtain tuyere control valves)

　　4. 固定百叶(侧墙格栅风口，开侧墙格栅风口)

　　4. Fixed louvers (side wall grille vent, side wall grille vent)

　　5. 风口过滤器(铝合金过滤器、钢网过滤器)

　　5. Tuyere filter (aluminium alloy filter, steel mesh filter)

　　6. 防雨百叶风口(单层防雨百叶、双层防雨百叶、自挂防雨百叶)

　　6. Rain-proof louvers (single-layer, double-layer and self-hanging louvers)

　　7. 扩压器(方形、矩形扩压器、lfk-7动叶缝扩压器、条状直扩压器、平叶扩压器)

　　7. Diffuser (square, rectangular diffuser, lfk-7 movable blade gap diffuser, strip diffuser, flat blade diffuser)
