Abstract
The utility model discloses a kind of automobile that prevents and overflow the exhaust pipe device of water final vacuum water inlet tube, the outlet pipe and the tube wall that comprise L shape are equipped with the exhaust pipe mouth of meeting water undergoes rapid expansion rubber.The object of design L shape outlet pipe is that water level first soaks exhaust pipe mouth when reaching main body exhaust gas pipe height, triggers the rubber on exhaust pipe mouth sidewall, makes its undergoes rapid expansion, blocking exhaust pipe mouth, stops water to continue to enter main exhaust and then damage motor.Hydro-expansive rubber is pasted or screw is fixed on relief opening inwall.Hydro-expansive rubber is made by natural rubber, styrene butadiene rubber and water-absorbing resin and polyacrylic acid sodium, and the component of water-absorbing resin is higher, and expanded rubber expansion rate of water absorption is higher.Expanded rubber produces 2-3 dilatancy doubly after meeting water, is full of space, and produces huge contact, thoroughly prevents infiltration.Expanded rubber water-swellable 3 times, its thickness is 1/5th of relief opening radius, closes relief opening completely after realizing meeting water.The relief opening that hydro-expansive rubber is housed, independent of main body outlet pipe, is threaded connection in main body outlet pipe, to be convenient for changing.
Description
Technical field
The utility model relates to a kind of automobile exhaust pipe of water-inlet-proof, the L shape outlet pipe of a kind of exhaust pipe mouth configuration of specific design expanded rubber.
Background technique
When running into heavy rain in automobile running and occur ground degree of depth ponding, if water level is higher than outlet pipe position, water enters outlet pipe by relief opening, and flows into engine combustion cylinder under hydraulic pressure, causes automobile flameout, even engine damage.
Disclosed in the utility model, water-inlet-proof automobile exhaust pipe, is equipped with hydro-expansive rubber at relief opening, when automobile runs into deep water, the rapid water-swellable of expanded rubber closed row gas port, stop water to enter outlet pipe and motor, now allow automobile flameout, can ensure that automobile is not damaged.L shape outlet pipe of the present utility model makes relief opening contact water prior to main exhaust, closes there to be the sufficient time to realize relief opening.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of automobile exhaust pipe of water-inlet-proof, prevents automobile from forming damage by outlet pipe water inlet during ponding to motor.
For solving the problems of the technologies described above, the technical solution of the automobile exhaust pipe of the utility model design water-inlet-proof is:
Comprise main body outlet pipe and the L-shaped structure of relief opening, exhaust pipe inwall is installed and is met water undergoes rapid expansion rubber.Expanded rubber is covered with exhaust pipe inwall completely, and available waterproof glue is pasted or is screwed in inner-walls of duct.
Described hydro-expansive rubber is by the component of adjustment water-absorbing resin, and make its water-swellable 3 times of volumes, then its thickness can be designed to 1/5th of relief opening radius, closes relief opening completely after can realizing meeting water.
The described relief opening that expanded rubber is housed, independent of main body outlet pipe, is threaded connection in main body outlet pipe, to be convenient for changing.
The technique effect that the utility model can reach is:
The utility model design water-inlet-proof automobile exhaust pipe, is equipped with hydro-expansive rubber at relief opening, when automobile runs into deep water, the rapid water-swellable of expanded rubber closed row gas port, stop water to enter outlet pipe and motor, now allow automobile flameout, can ensure that automobile is not damaged.L shape outlet pipe of the present utility model makes relief opening contact water prior to main exhaust, closes there to be the sufficient time to realize relief opening.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the automobile exhaust pipe plan view of the utility model water-inlet-proof;
Fig. 2 is the automobile exhaust pipe relief opening longitdinal cross-section diagram of the utility model water-inlet-proof;
Fig. 3 is the automobile exhaust pipe relief opening view in transverse section of the utility model water-inlet-proof;
Embodiment
As shown in Figure 1, the automobile exhaust pipe of the utility model water-inlet-proof, comprises the hydro-expansive rubber on outlet pipe main body, the exhaust pipe L-shaped with main body outlet pipe and exhaust pipe inwall;
The relief opening that expanded rubber is housed, independent of main body outlet pipe, is threaded connection in main body outlet pipe;
As shown in Figure 2, the thickness of the hydro-expansive rubber on exhaust pipe inwall much smaller than diameter of outlet, the patency that is vented when ensureing automobile normal running;
When ensureing hydro-expansive rubber intensity, increasing the ratio of water-absorbing resin as far as possible, to increase its expansivity, so just can reduce the thickness of hydro-expansive rubber;
As shown in Figure 3, hydro-expansive rubber is covered with exhaust pipe inwall, and when there being water to enter relief opening, expanded rubber, from tube wall all directions to center swell, forms relief opening and closes, thus stops water to enter main body outlet pipe.
Claims (5)
