Description

Novel blast pipe of efficient

Technical Field

The utility model relates to an automobile parts technical field, concretely relates to novel blast pipe of efficient.

Background

The exhaust pipe of the automobile is a common automobile accessory, and the air inlet of the exhaust pipe is connected with air exhausted from an engine and exhausted from the air outlet of the exhaust pipe, so that the engine works normally and certain noise reduction effect is achieved.

In recent years, the number of automobiles is rapidly increased, and the accompanying traffic noise pollution phenomenon is increasingly prominent. The most important noise of the automobile comes from an exhaust system of the automobile, namely, the exhaust emission noise of the automobile, the existing automobile exhaust pipe realizes the effect of reducing the noise by installing a silencer, but the silencer has a complex structure and is inconvenient to install. On the other hand, some accidental conditions easily cause the exhaust pipe to deform and even corrode, the service life is influenced, frequent maintenance and replacement are needed, and time and labor are wasted.

Disclosure of Invention

An object of the utility model is to provide a novel blast pipe of efficient to the not enough of actual life condition and prior art.

The utility model provides a novel blast pipe of efficient, include the exhaust person in charge, purifier and the exhaust branch pipe that sets gradually along the gas discharge direction, the exhaust branch pipe includes inner tube and outer tube, inner tube and outer tube seamless connection, the outer tube is close to orificial one side and is symmetrical wedge-shaped strengthening rib for the cross-section, the nose end of inner tube still is equipped with the cover that shelters from that has close net to prevent that the foreign matter from getting into.

Further, the outer pipe is a stainless steel pipe.

Furthermore, a plurality of layers of silencing nets are arranged in the exhaust main pipe.

Further, the purification device is a three-way catalyst.

Further, the reinforcing rib is solid.

Further, the outer surface of the outer tube is treated with a special color.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model relates to a novel high-efficiency exhaust pipe, which comprises an inner pipe and an exhaust branch pipe of an outer pipe which are connected in a seamless way, wherein the pipe orifice end of the inner pipe is provided with a shielding cover with a dense grid, which can prevent foreign matters from entering to block a pipeline; one side of the outer pipe close to the pipe orifice is provided with reinforcing ribs with symmetrical wedge-shaped sections, so that the effects of pressurization and turbulence can be achieved, and the exhaust is smoother; on the other hand, the solid reinforcing ribs ensure the integral strength of the structure, can play a good role in protection and reinforcement, prevent the inner pipe from deforming and corroding, prolong the service life of the exhaust pipe, increase the heat dissipation area and have a certain heat dissipation effect; the outer surface of the outer pipe is processed by special colors, so that the whole image of the exhaust pipe is more attractive, and better experience is provided for customers. The utility model relates to a rationally, the function is practical, still has characteristics such as simple structure, cost are lower, modern design, has very big market prospect.

Detailed Description

In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following description will explain specific embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be obtained from these drawings without inventive effort. In addition, the term "orientation" merely indicates a relative positional relationship between the respective members, not an absolute positional relationship.

Please refer to fig. 1 and fig. 2. The utility model relates to a novel blast pipe of efficient, include that the exhaust that sets gradually along gas discharge direction is responsible for 1, purifier 2 and exhaust branch 3, and exhaust branch 3 includes inner tube 30 and outer tube 31, and inner tube 30 and outer tube 31 seamless connection, outer tube 31 are close to orificial one side and are symmetrical wedge-shaped strengthening rib 32 for the cross-section, and the nose end of inner tube 30 still is equipped with the cover 33 that shelters from that has close net to prevent that the foreign matter from getting into.

In this embodiment, the exhaust gas that automobile engine produced gets into exhaust main pipe 1 through the air inlet, in whole process, can produce very big noise, not only can cause the influence to the surrounding environment, also is very big burden to blast pipe self, even weaken before reaching the blast pipe, still need establish multilayer noise reduction net 34 in exhaust main pipe 1, further weaken the noise, the exhaust main pipe 1 outside can also set up the amortization cotton, can play certain noise reduction effect like this.

Immediately following the exhaust main 1 is a purification apparatus 2, and in the present embodiment, the purification apparatus 2 employs a three-way catalyst. Automobile exhaust contains a large amount of harmful substances including carbon monoxide, nitrogen oxides, hydrocarbons, solid suspended particles and the like, which not only directly endanger human health, but also have a profound influence on the environment of human life, so that automobile exhaust needs to be purified to meet emission standards.

For traditional individual layer exhaust branch, the utility model discloses an inside and outside pipe seamless connection constitutes exhaust branch 3. Outer tube 31 is nonrust steel pipe, and its tip is solid strengthening rib 32, and on the one hand, the bulk strength of 3 structures of exhaust branch has been guaranteed to solid strengthening rib, can play fine protection and reinforcing effect, prevents that the inner tube from warping and receiving the corruption, has improved the life of blast pipe, and on the other hand can play certain syllable-dividing effect. The section of the reinforcing rib 32 is wedge-shaped, and is horn-shaped as a whole, so that the effects of pressurization and turbulence can be achieved, and the exhaust is smoother.

The mouth end of the inner pipe 30 is also provided with a shield cover 33 with a dense mesh to prevent foreign matter from entering and clogging the exhaust pipe.

The outer surface of the outer pipe 31 is processed by special colors, so that the whole image of the exhaust pipe is more attractive, and better experience is provided for customers.

The general exhaust system is modified, only the tail section of the exhaust pipe is involved, the diameter of the tail part of the exhaust pipe can be properly increased, the structural form of the silencer can be changed, the air flow passing through the unit area is increased, and therefore the exhaust emission is smoother. The most basic modification is to sleeve a more beautiful stainless steel sheath on the tail end of the exhaust pipe, and the stainless steel exhaust pipe has the advantages of low price, convenient installation and no influence on the original vehicle. The deep modification is to saw the tail section of the original vehicle exhaust pipe, weld a special tail throat at the cut-off part, or directly replace the tail throat of the original special vehicle pushed by different brands.

Foretell repacking scheme, or to the blast pipe of car cause permanent damage, to overall structure unfavorable, or the effect is not obvious, even bad material rusts very easily for a long time, can make the whole car more pleasing to the eye.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described.
