螺旋风管抱箍式连接抱箍式连接每一管段的两端轧制成鼓筋,并使及一端缩为小口.装置时按气流方向把小口插入大口,外面用钢制拖箍将两个管端的鼓筋抱紧连接最后用螺栓穿在耳环中固定拧紧做法。
1. The two ends of each pipe section are rolled into drum bars and
one end is shrunk into a small orifice. The small orifice is inserted
into the big orifice according to the direction of air flow. The drum
bars of the two pipe ends are tightly connected with the steel towing
hoop outside. Finally, the drum bars of the two pipe ends are fixed and
tightened with bolts through the earrings.
2.螺旋风管插接式连接插接式连接主要用于矩形或圆形风管连接,先制作连接管然后插入两侧风管再用自攻螺钉或拉柳钉将及紧密固定。
2. Spiral air duct plug-in connection is mainly used for
rectangular or circular air duct connection. The connecting pipe is made
first, then inserted into both sides of the air duct, and then fixed
tightly with self-tapping screw or willow nail.
3.螺旋风管插条式连接插条式连接于矩形风管连接将不同形式的插条插入风管两端,然后压实
3. Spiral air duct plug-in type connecting to rectangular air duct
connecting to insert different forms of plugs into both ends of the air
duct, and then compact
