Abstract
The utility model relates to a sealer for a vehicle exhaust, which is used for the sealing connection between the exhaust manifold and an exhaust. A seal is arranged on the connection surface of the utility model, the outer diameter of the seal is composed of a big stepped post, a small stepped post and a conical stepped surface, the inner hole of the seal is composed of a bottom big hole, a middle small hole and an upper conical hole. The apertureof the inner hole of the exhaust manifold corresponds to the small stepped post of the seal, the hole opening of the inner hole which is in a cone shape corresponds to the conical stepped surface of the seal, and the hole opening of the exhaust has a convex ring to correspond to the bottom big hole of the seal. The utility model has tight butting tightness without leakage, and is installed one time without the need of repeatedly tightening. The utility model has the advantages of high safety, noise and pollution reduction and long service life.
Description
The utility model relates to auto parts machinery, and concrete is a kind of automobile exhaust tube sealing device.
BJ492Q series in China's domestic automobile, liberation CA141 series, vehicles such as east wind EQ140 series, its engine exhaust pipe sealing gasket (to call sealing gasket in the following text) prolongs for a long time always uses sheet copper, or the ring liner of other metal parcel asbestos product filling, though it is simple in structure, easy to use, but because it is being subjected to high temperature always, the fierce impact of high pressure exhaust gas, be subjected to simultaneously the distortion and the high temperature coke powder of fastening flange again, ablate, defectives such as defect splits, sealability can reduce greatly, damages repeatedly, thereby causes a large amount of poisonous gas leakages, except that the human body physical and mental health is had the bigger infringement, unnecessary public noise and pollution have been increased again.When vehicle is repaiied the guarantor, as long as dismounting once, will change once this pad simultaneously, general every chassis needs to change 2-3 more than every year, and this is again a significant wastage to resource.Therefore, the sealing of asbestos seal pad, reliability, soundness, useful life longevity are all relatively poor.Perplexing vast department for a long time and driving personnel and trained service personnel, is to leave no choice but solve and a difficult problem not being resolved as yet.So, be necessary engine exhaust pipe sealing gasket old, traditional, that fall behind is updated, to improve its its usage economy.
The purpose of this utility model provides a kind of automobile exhaust tube sealing device, makes its Butt sealing tight, does not reveal, and does not need repeatedly fasteningly, safe in utilization after the disposable installation, reduces noise and pollution, long service life.
The purpose of this utility model is achieved in that
A kind of automobile exhaust tube sealing device is used for being tightly connected between automobile exhaust manifold and the outlet pipe, and this outlet pipe and gas exhaust manifold respectively have flange plate to connect with bolt, is provided with a sealing gasket on its junction surface, it is characterized in that:
The external diameter of described sealing gasket is made up of large and small rank post and terrace, and this terrace is for becoming the conical surface at α angle with level, and the endoporus of sealing pad is made up of bottom big order-opening, hole, rank, middle part, top taper hole, and this taper hole becomes the β dihedral to become waste gas to induce band with center line;
The endoporus aperture of described gas exhaust manifold is corresponding with the small step column of sealing gasket, and the aperture of this endoporus is a taper hole, and its taper is corresponding with the taper terrace that becomes the α angle of sealing gasket;
The aperture of described outlet pipe has the bottom big order-opening of bulge loop and sealing gasket corresponding.
The purpose of this utility model can also realize by following measure:
The α angle of described sealing gasket external diameter terrace is between 10-25 °, and the β angle of the central upper taper hole of described sealing gasket is between 20-40 °.
The α angle of described sealing gasket external diameter terrace is 15 °, and the β angle of the central upper taper hole of described sealing gasket is 30 °.
Described sealing gasket is made with metal.
The utility model has following actively useful effect:
1. its Butt sealing is tight, does not reveal.And in sealing brace circle, be provided with 30 degree waste gas and induce band, it is unblocked to be convenient to waste gas.Do not need repeatedly simultaneously fasteningly after the disposable installation, just can reach reliably firm purpose.And use that can prolonged and repeated continuous permanent property, this is all incomparable maximum characteristics of other existing liner.
2. be suitable for all temps of motor.Because the pure metal manufacturing, the compressive strength height is not afraid of and is ablated and burnt baking.Therefore in all temps atmosphere, can not damage, safe in utilization, improved working efficiency greatly.
3. adopt this product can reduce noise and pollution greatly.Because sealing is higher, the noise conduction is less, and the contaminativity of driving indoor air will disappear, and so just helps driver and other occupants' physical and mental health, can make the driver energetic, and the safe driving vehicle makes passenger's ride comfort.
4. the economic benefit position is considerable.Because the metallic material aboundresources, its use patience is hundred times of crude asbestos liner, avoids maintenance and replacing at ordinary times, uses effective serviceability rate permanent, has just improved economic benefit virtually.In the long term, this product has a extensive future, and produces by batch and can save every materials 40-50mm of former outlet pipe left and right sides high-quality tubing.
Now in conjunction with the accompanying drawings with preferred embodiment.
