The excessive deformation of strong-willed sealing ring and make seal failure, slight crack, which occurs, in sealing ring will lead to gas leakage, and engine consumption increases, unfavorable
In the use of people；
Engine can generate high-temp waste gas at work and is discharged by exhaust pipe, existing exhaust pipe seal gasket, which is conducted heat, to expire,
The vibration of engine cavity cannot be absorbed, when high temperature is easy to fall off, is unfavorable for heat transfer, for this purpose, we have proposed a kind of engines
Exhaust pipe sealing ring.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and it is simple, at low cost, no to provide a kind of structure
Sealing ring easily-deformable, resistant to high temperature, including connection ring, bellows, fixed ring, link block, fixed block and sealing ring, the connection
Ring side is fixedly connected with bellows, and the bellows is fixedly connected with fixed ring, the bellows far from the side of connection ring
Inner wall is fixedly connected with sealing ring, and the connection ring offers through-hole far from the side of bellows, and through-hole is connected with bellows
Logical, the through-hole is fixed with sealing ring, the sealing ring outer wall and the fixed company of ripple inside pipe wall close to the insertion of the side of bellows
It connects, the link block offers pilot hole far from the side of bellows, and pilot hole is connected with bellows, and the fixed ring is remote
Side from bellows is symmetrically fixedly connected with link block, and the fixed ring is fixedly connected with fixation far from the side of bellows
Block.
Preferably, the connection ring and fixed ring outer wall are coated with ceramic.
Preferably, the connection ring and fixed ring are a kind of fluoroplastics component.
Preferably, the bellows is a kind of Teflon member.
Preferably, the connection ring is fixedly connected with limited block far from the side of bellows.
The beneficial effects of the utility model are:
1, the utility model is welded fixed ring and automobile engine by fixed block and link block, and exhaust pipe is inserted
Enter and be fixed with sealing ring in connection ring, bellows itself can replace elastic element, and reduction exhaust pipe is in discharge gas
Pressure prevents from deforming, can be more stable when engine is operated, and prevents vibration from generating slight crack, and leakproofness is stronger.
2, the utility model connection ring and fixed ring are heat-resisting, high temperature resistant, and bellows made of polytetrafluoroethylene material is thermally conductive
Fastly, the design of surface V-groove increases the contact area with air, so that heat dissipation is faster, can also have one in engine luggine
Fixed compensation and shock attenuation result, sealing ring deformation when preventing high temperature, prevents from falling off, to extend whole service life.
