Abstract
The utility model relates to an automobile exhaust pipe device, in particular to a backflow-preventing device of an automobile exhaust pipe and aims at providing a device for preventing water from flowing into the automobile exhaust pipe. For achieving the purpose, the technical scheme is that the backflow-preventing device of the automobile exhaust pipe comprises an exhaust pipe and is characterized in that the exhaust pipe consists of a front portion, a middle cavity and a tail portion. The inner diameter of the middle cavity is larger than that of the front portion and that of the tail portion, a first exhaust port is arranged at the tail portion, the middle cavity is upward provided with a second exhaust port, and the second exhaust port is provided with an auxiliary exhaust plug. Two backflow-preventing water films are arranged in the pipe at the tail portion and are tapered, an opening is arranged at the top of a tapered shape, and the bottom of the tapered shape is fixed in the pipe at the tail portion.
Description
Technical field
The utility model relates to a kind of exhaust system, relates in particular to a kind of automobile exhaust pipe backward flowing preventing device.
Background technique
Automobile exhaust pipe is to be the waste gas behind the eliminating engine combustion, and in use, because common automobile exhaust pipe is arranged on the automobile bottom, in the highway section that runs into rainy weather or approach ponding, the lower outlet pipe in position causes that very easily water pours in down a chimney air inlet-outlet pipe, causes motor to damage easily.Also do not occur and at automobile exhaust pipe the anti-automobile that pours in down a chimney is set specially in the market.
Summary of the invention
The purpose of this utility model provides a kind of anti-sealing and irritates the interior device of admission vehicle exhaust pipe.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of automobile exhaust pipe backward flowing preventing device, comprise outlet pipe, it is characterized in that outlet pipe is made up of front portion, middle part cavity, afterbody, middle part cavity internal diameter is built-in and afterbody internal diameter greater than the front portion, afterbody arranges first relief opening, and the middle part cavity upwards has second relief opening, and second relief opening arranges the auxiliary exhaust plug, two anti-films of pouring water are set in the afterbody caliber, the described anti-film of pouring water is taper, and conical top has opening, and conical lower portion is fixed in the afterbody caliber.
According to described automobile exhaust pipe backward flowing preventing device, it is characterized in that described auxiliary exhaust plug uses aluminum alloy material.
Advantage of the present utility model is that product structure is simple, and cost of production is low, can effectively avoid water to pour in down a chimney admission vehicle exhaust pipe, has avoided the motor damage.
Description of drawings
Fig. 1 is sectional view of the present utility model.
Fig. 2 is stereogram of the present utility model.
In the accompanying drawing: 1, front portion; 2, middle part; 3, second relief opening; 4, auxiliary exhaust plug; 5, the anti-film of pouring water; 6, afterbody; 7, first relief opening.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model as shown in Figure 1, a kind of automobile exhaust pipe backward flowing preventing device comprises that row front portion 1, middle part 2, afterbody 6 are linked in sequence and form, and is characterized in that, described middle part 2 cavity internal diameters are greater than anterior 1 internal diameter and afterbody 6 internal diameters, afterbody 6 arranges first relief opening 7, and middle part 2 upwards has second relief opening, 3, the second relief openings 3 auxiliary exhaust plug 4 is set, two anti-films 5 of pouring water are set in afterbody 6 calibers, the described anti-film 5 of pouring water is taper, and conical top has opening, and conical lower portion is fixed in afterbody 6 calibers.
According to described automobile exhaust pipe backward flowing preventing device, it is characterized in that described auxiliary exhaust plug 4 uses aluminum alloy material.
In concrete the enforcement, when afterbody is in the underwater, the anti-film 5 of pouring water can be to inner recess because hydraulic pressure, and anti-film 5 openings of pouring water are closed, and waste gas is assembled at the middle part, and pressure acquires a certain degree, and pushes auxiliary exhaust valve open, finishes toxic emission.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; common engineers and technicians make the technical solution of the utility model in related domain various modification and improvement all should fall into protection domain of the present utility model.
