Description

A kind of modified exhaust pipe of haulage vehicle

Technical field

The utility model relates to exhaust pipe more particularly to a kind of modified exhaust pipes of haulage vehicle.

Background technique

It is also more and more the phenomenon that ponding in city as summer rainwater recent years increases.Some automobiles are due to entering Ponding region causes to be vented water inlet tube, to cause vehicle failure, or even scraps.In response to the above problems, row in the prior art Tracheae can not solve.

Utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of transport vehicle Modified exhaust pipe, can solve the water inlet problem of automobile exhaust pipe.

The utility model is to be achieved by the following technical programs:

A kind of modified exhaust pipe of haulage vehicle, comprising:

Exhaust pipe, exhaust pipe inside are equipped with the first segment and second segment of shoulder hole structure, and the aperture of first segment is greater than second Section, first segment side wall are equipped with multiple exhaust holes；

Fixed part, fixed part are fixedly mounted on inside exhaust pipe, and fixed part is equipped with fixed part through-hole；

First, first shape is to cooperate the disc of second segment, and first is connect with fixed part by spring；

Second, second shape is cylinder, and first side wall is equipped with the hierarchic structure inside cooperation exhaust pipe Third section and the 4th section, second inside is equipped with unidirectional valve chamber, No.1 channel, No. two channels and No. three channels, unidirectional valve chamber Connection runs through second No.1 channel and through No. three channel of second the 4th section of side wall, and No. two channels connect No.1 channel And run through second third section side wall.

According to the above technical scheme, it is preferable that check valve is intracavitary to be equipped with spherical spool and one-way valve spring.

The beneficial effects of the utility model are: the automatic sealing package when exhaust pipe immerses ponding may be implemented by above structure It closes, and does not influence exhaust effect.

Detailed description of the invention

Fig. 1 shows the schematic view of the front view of the embodiments of the present invention.

In figure: 1. exhaust pipes, 2. first segments, 3. second segments, 4. exhaust holes, 5. fixed parts, 6. fixed part through-holes, 7. First, 8. springs, 9. second, 10. third sections, 11. the 4th sections, 12. unidirectional valve chambers, 13. No.1 channels, 14. No. two logical Road, 15. No. three channels, 16. spherical spools, 17. one-way valve springs.

Specific embodiment

In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing The utility model is described in further detail with most preferred embodiment.

As shown, a kind of modified exhaust pipe of haulage vehicle of the utility model, comprising:

Exhaust pipe 1, is equipped with the first segment 2 and second segment 3 of shoulder hole structure inside exhaust pipe, and the aperture of first segment is greater than the Two sections, first segment side wall is equipped with multiple exhaust holes 4；

Fixed part 5, fixed part is fixedly mounted on inside exhaust pipe, and fixed part is equipped with fixed part through-hole 6；

First 7, first shape is to cooperate the disc of second segment, and first is connect with fixed part by spring 8；

Second 9, second shape is cylinder, and first side wall is equipped with the hierarchic structure inside cooperation exhaust pipe Third section 10 and the 4th section 11, second inside is equipped with unidirectional valve chamber 12, the channel 14 of No.1 channel 13, two and No. three channels 15, unidirectional valve chamber connection runs through second No.1 channel and through No. three channels of second the 4th section of side wall, No. two channels It connects No.1 channel and runs through second third section side wall.

In the present embodiment, when normal exhaust, vehicle exhaust enters No.1 channel, and No. two channels are by the of exhaust inside pipe wall One section of closing, more and more vehicle exhausts open check valves, are discharged into the second segment of exhaust pipe from No. three channels, and the of exhaust pipe The opening of two sections of connection exhaust pipes；

When the opening of exhaust pipe is submerged into ponding, the pressure of ponding is held essentially constant, and exhaust pipe first segment The tail gas of middle accumulation is more and more, cause first and second it is mobile to exhaust pipe opening direction, until second outer wall Hierarchic structure is limited by the hierarchic structure inside exhaust pipe, and No. three channels are connect with the exhaust hole of exhaust pipe first segment at this time, Exhaust pipe can be discharged along No.1 channel, No. three channels, exhaust hole in vehicle exhaust, while exhaust pipe is by first and second Portion's closing.

The self-closed when exhaust pipe immerses ponding may be implemented by above structure, and do not influence exhaust effect.

According to above-described embodiment, it is preferable that check valve is intracavitary to be equipped with spherical spool and one-way valve spring.First and second Portion's cooperation constitutes unidirectional valve chamber.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the protection scope of the utility model.
