Description

Heavy steam exhaust spiral corrugated pipe

Technical Field

The utility model mainly relates to an exhaust technical field especially relates to a heavy vapour exhaust helical bellows.

Background

The exhaust corrugated pipe is a shock-resistant elastic compensation device arranged on an exhaust pipe section of an engine, and aims to compensate shaft displacement of an engine exhaust pipe caused by expansion and contraction of heat during use and reduce the possibility of breakage of the exhaust pipe or damage of other connecting pieces caused by vibration of the engine.

The straight tube structure is mostly adopted by the exhaust corrugated pipe in the current market, so that the heat exchange area between tail gas and a closed cavity is too small when the tail gas passes through the exhaust pipe, the actual cooling effect is poor, the exhaust corrugated pipe is easy to crack and damage due to the high vibration frequency of high temperature in use, and the service life is short.

SUMMERY OF THE UTILITY MODEL

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.
