Abstract
The utility model discloses a corrugated pipe for an exhaust system. The corrugated pipe comprises two connecting flanges, a corrugated outer pipe and a diversion inner pipe, the two connecting flanges are fixed to two ends of the corrugated outer pipe respectively; the diversion inner pipe is arranged inside the corrugated outer pipe; and the air inlet end is fixed on the corrugated outer pipe, and the air outlet end is suspended. The corrugated pipe is reasonable and simple in structure; the diversion inner pipe is arranged inside the corrugated outer pipe, so that high-temperature airflow is prevented from impacting the corrugation of the corrugated outer pipe directly, and the cracking and air leakage of the corrugated outer pipe are avoided. In addition, the diversion inner pipe is fixed with one end of the corrugated outer pipe, and the other end of the corrugated outer pipe is suspended, so that the corrugated outer pipe can be stretched and retracted arbitrarily and is convenient to install.
Description
Technical field
The utility model relates to engine art, particularly a kind of vent systems bellows.
Background technique
For satisfying the installation of car load, reduce the interference of each system when assembling, produce mechanical failure, the many employings of automobile exhaust pipeline completely bellows connect.
Traditional vent systems bellows is under the continuous impact of engine exhaust system high temperature gas flow, and ripple position vapour lock is large in the pipe, and under alternation heat load and effect of vibration, easily cracking leaks gas, thereby affects the normal operation of vehicle.
The model utility content
The utility model is in order to overcome defective in the above-mentioned prior art, to provide a kind of rational in infrastructure simple, not the vent systems bellows of gas leakage easy to crack.
For achieving the above object, provide a kind of vent systems bellows according to the utility model, comprising: connecting flange, corrugated outer tube and water conservancy diversion inner tube; Connecting flange is two, is separately fixed at the two ends of corrugated outer tube; The water conservancy diversion inner tube is arranged on corrugated outer tube inside, and inlet end is fixed on the corrugated outer tube the unsettled setting in outlet side.
In the technique scheme, connecting flange, corrugated outer tube and water conservancy diversion inner tube are metal material.
In the technique scheme, the inlet end of water conservancy diversion inner tube is weldingly fixed on the corrugated outer tube.
Compared with prior art, the utlity model has following beneficial effect: this vent systems bellows structure is rationally simple, by the water conservancy diversion inner tube is arranged on corrugated outer tube inside, avoided high temperature gas flow directly to impact the ripple of corrugated outer tube, make its gas leakage not easy to crack.In addition, water conservancy diversion inner tube and corrugated outer tube one end are fixed, and the other end is unsettled, and be so that corrugated outer tube can stretch arbitrarily, easy for installation.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of vent systems bellows of the present utility model;
Description of reference numerals:
The 1-connecting flange, 2-corrugated outer tube, 3-water conservancy diversion inner tube.
Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.It will be appreciated that, mentioned in the following mode of execution of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction only are for convenience of explanation, do not represent the restriction to the concrete technological scheme of the utility model.
As shown in Figure 1 (arrow represents airintake direction among the figure), vent systems bellows of the present utility model comprises: connecting flange 1, corrugated outer tube 2 and water conservancy diversion inner tube 3.
Wherein, connecting flange 1 is metal material, is used for being connected with the outlet pipe of engine exhaust system.
Corrugated outer tube 2 is metal material, has with the same flexible and very high bending fatigue strength of sebific duct, and welding performance is good.Two connecting flanges 1 are weldingly fixed on respectively the two ends of corrugated outer tube 2.
Water conservancy diversion inner tube 3 also is metal material, be arranged on corrugated outer tube 2 inside, the suction port end of water conservancy diversion inner tube 3 (left end among the figure) is welded and fixed together with the left port inwall of corrugated outer tube 2, and the unsettled setting of air outlet end (right-hand member among the figure), so that bellows can stretch arbitrarily, and the length that is not subject to water conservancy diversion inner tube 3 restricts, and easy for installation.At this moment, the high temperature gas flow of engine exhaust system enters from water conservancy diversion inner tube 3 suction ports, flows out from the air outlet of water conservancy diversion inner tube 3, has avoided high temperature gas flow directly to impact the ripple place of corrugated outer tube 2, has improved the reliability of vent systems bellows.
This vent systems bellows structure is rationally simple, by the water conservancy diversion inner tube is arranged on corrugated outer tube inside, has avoided high temperature gas flow directly to impact the ripple of corrugated outer tube, makes its gas leakage not easy to crack.In addition, water conservancy diversion inner tube and corrugated outer tube one end are fixed, and the other end is unsettled, and be so that corrugated outer tube can stretch arbitrarily, easy for installation.
Above disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
