1.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

4.螺旋风管软管式连接软管式连接主要用于螺旋风管与部件(如散流器静压箱侧送风口等)相连装置时,软臂两端套在连接管外,然后用特制软卡把软管箍紧。

4. The spiral air pipe hose connection hose connection is mainly used to connect the spiral air pipe with the components (such as the static pressure box side air outlet of the diffuser) when the two ends of the flexible arm are sleeved outside the connection pipe, and then the hose is hoisted with a special soft card.
