Description
Technical field
The present invention relates to a kind of vent systems, belong to motor exhaust post-processing technology field.
Background technique
The vent systems of automobile refers to collects and the system of discharging waste gas, generally comprises gas exhaust manifold, catalytic converter, outlet pipe, silencing apparatus and tailpipe etc.Waste gas is converted into water and nitrogen oxide after catalytic converter condensation, form acid etching solution, corrosive liquid accumulation for a long time can make each parts of vent systems very easily produce corrosion and get rusty, and vent systems can be caused time serious to lose efficacy, and therefore Anti-corrosion design is the emphasis of exhaust system design.
The main method of current solution exhaust system corrosion problem is by upgrading material, namely perishable parts increase current material thickness in vent systems or use the material that corrosion-resistant higher grade, although the method can effectively occur by slowing down corrosion, material upgrade cost is higher.
" sacrificial anode " method of employing can under the prerequisite of material of not upgrading, and slowing down corrosion occurs, and effectively can solve the cost increase impact because upgrading material brings.Its principle mainly using metal stronger for reducibility as protection pole, be connected with protected metal and form galvanic cell, the metal that reducibility is stronger will consume as negative pole generation oxidation reaction, protected metal as positive pole just can avoid corrode.
Due to the traveling road conditions more complicated of automobile, sacrificed anticathode part need to adopt weld, be spirally connected, the mode such as riveted joint is fixed in perishable place.But need when preparing above-mentioned means of fixation to destroy adjacent material Organizational Structure, the former antiseptic property of material is easily destroyed.In addition, above-mentioned means of fixation easily produces gap, and corrosive liquid is easy to be stuck in these gaps, occurs " crevice corrosion ".
Vent systems is in use, as improper in the selection of anode means of fixation, causes anode part in use to come off from immovable point, will produce larger impact.Due to vent systems in use, constantly have air current flow, stronger air-flow blows anode part and runs helter-skelter in vent systems, easily produce abnormal sound on the one hand, collided by other parts in the anode that blows and vent systems on the other hand, cause this structure function to lose efficacy, affect the normal use of vent systems.
Therefore, be necessary to improve prior art.
