Abstract
The utility model discloses a sealing structure of a bend pipe and an exhaust pipe in an exhaust pipe inflow-prevention device. The sealing structure comprises the bend pipe. The upper end of the bend pipe is connected with the exhaust pipe through a location device which comprises an inner ring and an outer ring. The outer ring is fixedly installed in a pipe opening of the exhaust pipe, the inner diameter of the outer ring and the outer diameter of the inner ring are gradually reduced along the bend pipe insertion direction, the inner ring is sleeved on the bend pipe, and the inner ring and the bend pipe are inserted in the outer ring and firmly clamped by the outer ring. A plurality of annular grooves are arranged on the periphery of the inner ring, and a sealing ring protruding out of each annular groove is arranged in the annular groove. A plurality of annular grooves are arranged on the periphery of the bend pipe, and sealing rings protruding out of the annular grooves are arranged in the annular grooves. The annular grooves are respectively arranged on the peripheries of the inner ring and the bend pipe, and the sealing rings protruding out of the annular grooves are arranged in the annular grooves, so that sealing between the bend pipe and the inner ring and between the inner ring and the outer ring is achieved, and water is prevented from entering the exhaust pipe.
Description
Technical field
The utility model relates to a kind of Water-in proof device of automobile discharge pipe, particularly the sealing configuration of bend pipe and outlet pipe in the anti-water feed apparatus of a kind of outlet pipe.
Background technique
Usually the mounting point of automobile exhaust pipe is lower, generally in the automobile chassis bottom, the face depth of water is higher than again the chassis when the casual water route of automobile process, and traditional automobile exhaust pipe can't be kept out the outlet pipe water inlet to stopping working that automobile causes, and serious will cause water inflow of the engine.
When water being arranged or have other erosion to enter in the automobile exhaust pipe, traditional automobile exhaust pipe can only wait for that ponding or erosion to the corrosion of outlet pipe, finally cause outlet pipe to scrap.
A kind of anti-water feed apparatus of ad hoc meter, preliminary imagination is that a bend pipe is set, in bend pipe, be arranged side by side many in order to the tubule of exhaust, the lower end of bend pipe is equipped with the water check valve that is inclined relative to horizontal, water check valve comprises lid and the number ball identical with tubule that is covered with mesh, ball be separately positioned on each tubule mouth of pipe the below and and the tubule mouth of pipe between leave the gap; Ball has lighter weight, can throw off the tubule mouth of pipe under the effect of tail gas air-flow or block the tubule mouth of pipe under the buoyancy of water effect, thereby both prevent that water from entering, and does not hinder again tail gas to discharge.
The bend pipe upper end links to each other with outlet pipe by positioning device, described positioning device comprises inner ring and outer ring, the outer ring is fixed in the outlet pipe mouth of pipe, and the internal diameter of outer ring, the external diameter of inner ring diminish gradually along the bend pipe direction of insertion, and inner ring is enclosed within on the bend pipe, inner ring, bend pipe are inserted in the outer ring and by the outer ring and tighten, but find in the practice, sealing is good not, between bend pipe and the inner ring, have a little gap between inner ring and the outer ring, water still can enter into wherein.
The model utility content
The utility model has overcome above-mentioned the deficiencies in the prior art, provide a kind of anti-sealing to enter into the interior bend pipe of outlet pipe and the sealing configuration of outlet pipe, the sealing structure is the important component part in the anti-water feed apparatus of outlet pipe, has played the effect of water-based sealing.
The technical solution of the utility model is achieved in that
The sealing configuration of bend pipe and outlet pipe in the anti-water feed apparatus of a kind of outlet pipe, comprise bend pipe, the bend pipe upper end links to each other with outlet pipe by positioning device, described positioning device comprises inner ring and outer ring, the outer ring is fixed in the outlet pipe mouth of pipe, the internal diameter of outer ring, the external diameter of inner ring diminish gradually along the bend pipe direction of insertion, inner ring is enclosed within on the bend pipe, inner ring, bend pipe are inserted in the outer ring and by the outer ring and tighten, be provided with the multiple tracks circular groove in the inner ring periphery, in circular groove, be provided with the seal ring that protrudes from circular groove; Be provided with the multiple tracks circular groove in the bend pipe periphery, in circular groove, be provided with the seal ring that protrudes from circular groove.
As preferably, on inner ring periphery, bend pipe periphery, respectively be provided with three road circular grooves.
Adopted the beneficial effects of the utility model of technique scheme to be:
The utility model is being provided with respectively circular groove on inner ring periphery, bend pipe periphery, be provided with the seal ring that protrudes circular groove in circular groove, has realized between bend pipe and the inner ring, the sealing between inner ring and the outer ring, has prevented that water from entering in the outlet pipe.
Description of drawings
Fig. 1 is the sealed structural representation of bend pipe of the present utility model and outlet pipe;
Fig. 2 is the fractionation structural representation of inner ring, outer ring and bend pipe.
Embodiment
Embodiment of the present utility model is as follows:
Embodiment: the bend pipe in the anti-water feed apparatus of a kind of outlet pipe and the sealing configuration of outlet pipe, as shown in Figure 1, bend pipe 9 upper ends link to each other like this with outlet pipe 1, bend pipe 9 upper ends link to each other with outlet pipe 1 by positioning device, described positioning device comprises inner ring 16 and outer ring 5, and outer ring 5 is installed in the outlet pipe mouth of pipe, and the external diameter of the internal diameter of outer ring 5, inner ring 16 diminishes gradually along the bend pipe direction of insertion, inner ring 16 is enclosed within on the bend pipe 9, and inner ring 16, bend pipe 9 are inserted in the outer ring 5 and by outer ring 5 and tighten.
As shown in Figure 1, 2, be provided with 3 road circular grooves 17 in inner ring 16 peripheries, in circular groove 17, be provided with seal ring 18.In addition, be provided with multiple tracks circular groove 17 in bend pipe 9 peripheries, in circular groove 17, be provided with seal ring 18.
