The utility model has the advantages that the utility model relates to a kind of water proof type automobile exhaust pipes, the case where not increasing exhaust gas pipe height
Under, by the way that sealing gland cavity and super charge pipe are arranged in exhaust pipe, increase the gas pressure in exhaust pipe, be used to balance external
Portion's ponding pressure, prevents ponding from entering inside automobile exhaust pipe, realizes the waterproof of automobile exhaust pipe.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Appended drawing reference are as follows: upper exhaust pipe 1, electric three passes valve 2, super charge pipe 3, sealing gland cavity 4, pressure sensor 5,
Lower exhaust pipe 6, partition 7.
Specific embodiment
In the following description, a large amount of concrete details are given more thoroughly to manage in order to provide to the utility model
Solution.It is, however, obvious to a person skilled in the art that the utility model may not need it is one or more of these thin
It saves and is carried out.In other examples, in order to avoid obscuring with the utility model, for more well known in the art
Technical characteristic is not described.
As shown in Fig. 1, a kind of water proof type automobile exhaust pipe, comprising: upper exhaust pipe 1, electric three passes valve 2, be pressurized into
Tracheae 3, sealing gland cavity 4, pressure sensor 5, lower exhaust pipe 6.
Wherein, upper 1 one end of exhaust pipe is connected with automobile engine tail gas pipe or exhaust gas cleaner, the other end and gas
It is connected above envelope cavity 4；The side of upper exhaust pipe 1 is arranged in super charge pipe 3, in the super charge pipe 3 and upper exhaust
The junction of pipe 1, which is equipped with, to be connected below electric three passes valve 2 and lower exhaust pipe 6 and the sealing gland cavity 4.It is installing
When, three ports of electric three passes valve are connected and fixed with the nozzle of related pipe body respectively.Under Part load, it can adopt
It is reinforced with modes such as clamping or flanges.
As a preferred embodiment, the sealing gland cavity 4 is oval metal cavity, is an integral molding structure.As this
The main body of exhaust pipe in technical solution needs to guarantee the air-tightness and integral strength of exhaust pipe, is gas and ponding mutual extrusion
Stable place is provided.
As a preferred embodiment, lead between the sealing gland cavity 4 and upper exhaust pipe 1, sealing gland cavity 4 and upper exhaust pipe 1
It crosses screw thread to be connected, junction is provided with sealing ring.It can not only be convenient for changing the exhaust pipe of damage in this way, and can be improved
The leakproofness of exhaust pipe junction.
As a preferred embodiment, 4 bottom of sealing gland cavity is provided with pressure sensor 5.By pressure change, can survey
Measure the water-feeding deep in sealing gland cavity 4.
As a preferred embodiment, 3 other end of super charge pipe is connected with air compressor.It had been embodied
Cheng Zhong can provide pressure by air compressor for exhaust pipe, while can also be connected with other exhaust equipments on automobile, mention
For the gas of enough pressure, equilibrium water pressure.
As a preferred embodiment, the height of the sealing gland cavity 4 is 3~5 times of upper and lower 6 diameter of exhaust pipe.It can give
Into one sufficient cushion space of ponding of exhaust pipe, the excessively high exhaust pipe volume that will lead to of sealing gland cavity 4 becomes larger, and needs to change
