To the above-mentioned defect of prior art, the utility model provides a heavy vapour exhaust helical bellows, including first bellows 1, 1 lateral wall cover of first bellows is equipped with second bellows 2, 2 both ends of second bellows are equipped with first takeover 3 and second takeover 4 respectively, it is equipped with ring flange 5 all to overlap on first takeover 3 and the second takeover 4, mounting hole 6 has been seted up on ring flange 5, a plurality ofly have been seted up along 5 circumferencial directions of ring flange to mounting hole 6.
Preferably, the middle section part of the outer side wall of the first connecting pipe 3 is provided with a clamping groove 7.
Preferably, the flange on the first adapter 3 is clamped on the clamping groove 7.
Preferably, the flange on the second connecting pipe 4 is far away from the second corrugated pipe 2 and is connected by welding.
Preferably, the diameter of the inner side wall of the first connecting pipe 3 is smaller than that of the inner side wall of the second connecting pipe 4.
Preferably, the inner side wall of the second connecting pipe 4 is provided with a filter screen 8, and the filter screen 8 is positioned at the joint of the second connecting pipe 4 and the first corrugated pipe 1.
Preferably, the inner side wall of the first corrugated pipe 1 and the outer side wall of the second corrugated pipe 2 are attached.
The utility model has the advantages that:
the exhaust spiral corrugated pipe in the utility model adopts a double-layer structure, thereby avoiding the high-temperature airflow from directly impacting the second corrugated pipe, improving the reliability of the corrugated pipe of the exhaust system and further improving the vibration damping performance of the product; the first corrugated pipe can be protected from being damaged by external force through the filter screen arranged on the inner side wall of the second connecting pipe.
