Abstract
The utility model relates to a water inlet preventing device of an engine exhaust pipe, which is arranged in an exhaust port of the engine exhaust pipe. The water inlet preventing device is characterized in that the water inlet preventing device comprises at least three flexible valves, wherein the bottom ends of the valves are fixedly arranged on the pipe wall of the exhaust pipe, edges of two adjacent valves are overlapped, the top end of each valve is retracted to the center, and all of the valves are integrally closed to form a sealed tip. The water inlet preventing device has the advantages of simple structure, convenience in installation and good use effect.
Description
Technical field
The utility model relates to the anti-water feed apparatus of a kind of engines tail tracheae.
Background technique
Be used for the anti-water feed apparatus of motor car engine in the prior art generally in the following ways: thus a kind of be the height that improves the offgas duct outlet by installing pipe additional, be 201020518170.6 such as the patent No., patent name is for disclosing a kind of structure in " Water-in proof device of automobile discharge pipe ": comprise flexible pipe, one end of described flexible pipe has for the joint that is tightly connected with automobile exhaust pipe, flexible pipe away from an end of its joint have for the adsorbent equipment of automotive body secure fit; Water-in proof device of automobile discharge pipe of the present utility model adopts flexible pipe, when running into the darker situation of surface gathered water and maybe need to wade acroos a river, can be tightly connected with automobile exhaust pipe easily by described joint, then as required the other end of described flexible pipe is drawn the higher position of upper vehicle body, then fix by described adsorbent equipment, so indirectly the raise position of automobile exhaust pipe relief opening has solved that outlet pipe is not had by water logging and the problem of intaking.The defective of above-mentioned prior art is: flexible pipe needs interim the installation, needs dismounting after being finished, and therefore uses trouble, and complex structure, destroys the Integral automobile profile.
The model utility content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and a kind of simple in structure, easy for installation, anti-water feed apparatus of engines tail tracheae that using effect is good is provided.
The technical scheme in the invention for solving the above technical problem is: this engines tail tracheae is prevented water feed apparatus, be arranged on the relief opening of engines tail tracheae, it is characterized in that: the valve that comprises at least three flexibilities, the valve bottom is fixed on the tube wall of offgas duct, two adjacent cusp margins are superimposed, draw in to the center on every valve top, and all valve unitary closed form the tip of sealing.
The every plate shape size of valve described in the utility model is identical, and valve evenly distributes on the circumferencial direction of tube wall.
Valve described in the utility model bottom is provided with wedged interface, is fixed on the tube wall by this wedged interface valve sealing.Easy to process, good sealing effect.
Valve described in the utility model is rubber or silica gel material.
The utility model compared with prior art has the following advantages: the utility model is arranged on the tube wall of offgas duct, and valve has certain elasticity.When normal exhaust, thereby air-flow can be washed internally the tip of valve sealing open air-flow is discharged.When running into ponding, because the special shape of valve, current are blocked and can not pour in down a chimney into outlet pipe.The utility model low cost of manufacture, easy for installation, using effect is good.
