Abstract
The utility model discloses a kind of engine exhaust helical bellows, comprise body, body is formed by two to four layers of rolling stainless steel band, lines on body is continuous helical shape, and the distance between body two peaks is 10mm, and the distance between body peak and minimum point is 9mm, body one end is by the first adapter and triangle Flange joint, first adapter is integrated with body, and the body the other end is connected with square flange by the second adapter, and the second adapter is integrated with body.The utility model body is formed by two to four layers of rolling stainless steel band, body lines is continuous helical shape, distance between helicoids two peaks is 10mm, distance between peak and minimum point is 9mm, due to the utility model body peak between distance, distance between peak and minimum point comparatively large, so the surface area of body threaded pipe is larger, and the threaded pipe of body is sequential like, make body better flexible, anti seismic efficiency is good, and thermal diffusivity is better.
Description
Technical field
The utility model belongs to the venting gas appliance of motor, more specifically relates to a kind of helical bellows of engine exhaust.
Background technique
Common exhaust expansion bellows rolling stainless steel band forms, and is welded into tubular after steel band blanking rolls, the nestable rear shaped by fluid pressure together of even weld offset angular.Exhaust expansion bellows, as at the flexible compensation device of the antidetonation of engine exhaust conduit, compensates the axial displacement that engine exhaust pipe in use causes because expanding with heat and contract with cold, and reduction engine luggine causes outlet pipe to rupture or other link probability of damages.Exhaust expansion bellows is in the market due to the restriction of the thread size of bellows, and the surface area of bellows is less, its shockproof properties and heat dispersion to be improved.
Embodiment
In order to solve the problems of the technologies described above, the utility model provides a kind of anti seismic efficiency and thermal diffusivity better and the higher engine exhaust helical bellows of intensity.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is as follows:
A kind of engine exhaust helical bellows, comprise body, body is formed by two to four layers of rolling stainless steel band, lines on body is continuous print helical, and the distance between two peaks of body is 10mm, and the distance between the peak of body and minimum point is 9mm, one end of body is by the first adapter and triangle Flange joint, first adapter is integrated with body, and the other end of body is connected with square flange by the second adapter, and the second adapter is integrated with body.
Its beneficial effect is: body of the present utility model is formed by the rolling stainless steel band of two to four layers, the lines of body is continuous print helical, distance between two peaks of helicoids is 10mm, distance between peak and minimum point is 9mm, due to body of the present utility model peak between distance, distance between peak and minimum point larger, so the surface area of the threaded pipe of body is larger, and the threaded pipe of body is sequential like, make the flexibility of body better, anti seismic efficiency is good, and thermal diffusivity is better.
In some embodiments, the thickness of Stainless Steel Band is 0.2 ~ 0.25mm.
Its beneficial effect is: the THICKNESS CONTROL of wall scroll Stainless Steel Band, at 0.2 ~ 0.25mm, makes the thickness of whole body at 0.4mm ~ 10mm, and the body fastness in this thickness range is better.
In some embodiments, the internal diameter of the first adapter is less than the internal diameter of body, and the internal diameter of the second adapter is less than the internal diameter of body.
Its beneficial effect is: the gas access place of the utility model end is stepped, is accessed by body in the vent systems of motor, flows than smoothly, can be discharged by the waste gas in engine exhaust system in time when waste gas drains into the utility model end.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, the utility model discloses a kind of engine exhaust helical bellows, comprises body 1, and body 1 is formed by two to four layers of rolling stainless steel band.The thickness of every layer of Stainless Steel Band is 0.2 ~ 0.25mm.Lines on body 1 is continuous print helical, and the distance between two peaks 11 of the helical corrugation on body 1 is 10mm, and the distance between the peak 11 of the helical corrugation on body 1 and minimum point 12 is 9mm.One end of body 1 is connected with triangle flange 3 by the first adapter 2, and the first adapter 2 is integrated with body 1.The other end of body 1 is connected with square flange 5 by the second adapter 4, and the second adapter 4 is integrated with body 1.The internal diameter of the first adapter 2 is less than the internal diameter of body 1, and the internal diameter of the second adapter 4 is less than the internal diameter of body 1.
Body 1 of the present utility model is formed by the rolling stainless steel band of two to four layers, the lines of body 1 is continuous print helical, distance between two peaks 11 of helicoids 1 is 10mm, distance between peak 11 and minimum point 12 is 9mm, due to body 1 of the present utility model peak 11 between distance, distance between peak 11 and minimum point 12 larger, so the surface area of the threaded pipe of body 1 is larger, and the threaded pipe of body 1 is sequential like, make the flexibility of body 1 better, good damping effect, thermal diffusivity is better.The THICKNESS CONTROL of wall scroll Stainless Steel Band, at 0.2 ~ 0.25mm, makes the thickness of whole body at 0.4mm ~ 10mm, and the body fastness in this thickness range is better.The gas access place of the utility model end is stepped, accesses in the vent systems of motor by body 1, flows than smoothly, can be discharged by the waste gas in engine exhaust system in time when waste gas drains into the utility model end.
Above-described is only the preferred implementation of the utility model engine exhaust helical bellows; it should be pointed out that for those of ordinary skill in the art, under the prerequisite not paying creative work; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of the engine exhaust helical bellows of the utility model one mode of execution.
