Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of structure simple, slows down the Novel automobile exhaust pipe of the pressure of waste gas.
The utility model solves the technological scheme that its technical problem adopts: a kind of Novel automobile exhaust pipe, comprise the expansion housing and silencer that are connected by bend pipe, expansion housing is built-in with dividing plate and expanding shell intracoelomic cavity is separated into the first expansion chamber, the second expansion chamber and the 3rd expansion chamber, be communicated with by pipe between first expansion chamber and the second expansion chamber, be communicated with by pipe between the second expansion chamber and the 3rd expansion chamber; Described first expansion chamber sidewall is connected with suction tude, and the 3rd expansion chamber offers air outlet; Described air outlet is connected with bend pipe; Described silencer comprises pipe in the inside and outside noise reduction shell that arranges and perforate, and be filled with silencing cotton between pipe in noise reduction shell and perforate, in perforate, tube cavity forms air-flow path, and air-flow path one end is connected to bend pipe, and the air-flow path the other end is provided with steam outlet pipe.
Further, the first described expansion chamber is built-in with the air inlet interpolation pipe be connected with suction tude, and the 3rd expansion chamber is built-in with the interpolation pipe of giving vent to anger be connected with air outlet.
Further, in the first described expansion chamber, air inlet interpolation pipe and pipe are in staggered distribution, and pipe is positioned at above air inlet interpolation pipe; Give vent to anger in described 3rd expansion chamber interpolation pipe and pipe is in staggered distribution, and interpolation pipe of giving vent to anger is positioned at above pipe.
Further, described silencing cotton is high temperature resistant and glass wool layer that is good muffling effect.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, easy and simple to handle, air-flow mutually impacts in the first expansion chamber, the second expansion chamber and the 3rd expansion chamber, air-flow velocity is slowed down, slow down the waste gas after pressure and enter silencer by bend pipe, waste gas noise absorbs through silencing cotton and realizes silencing function.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. expansion housing, 2. dividing plates, 3. the first expansion chamber, 4. the second expansion chamber in figure, 5. the 3rd expansion chamber, 6. pipe, 7. suction tude, 8. air outlet, 9. bend pipe, 10. air inlet interpolation pipe, 11. give vent to anger interpolation pipe, 12. noise reduction shells, 13. silencing cottons, pipe in 14. perforates, 15. air-flow paths, 16. steam outlet pipes.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Novel automobile exhaust pipe as shown in Figure 1, comprise the expansion housing 1 and silencer that are connected by bend pipe 9, expansion housing 1 is built-in with dividing plate 2 and expansion housing 1 inner chamber is separated into the first expansion chamber 3, second expansion chamber 4 and the 3rd expansion chamber 5, be communicated with by pipe 6 between first expansion chamber 3 and the second expansion chamber 4, be communicated with by pipe 6 between the second expansion chamber 4 and the 3rd expansion chamber 5; First expansion chamber 3 sidewall is connected with suction tude 7, and the 3rd expansion chamber 5 offers air outlet 8; Air outlet 8 is connected with bend pipe 9; Described silencer comprises pipe 14 in the inside and outside noise reduction shell 12 that arranges and perforate, silencing cotton 13 is filled with between pipe 14 in noise reduction shell 12 and perforate, in perforate, pipe 14 inner chamber forms air-flow path 15, and air-flow path 15 one end is connected to bend pipe 9, and air-flow path 15 the other end is provided with steam outlet pipe 16.
