Abstract
The utility model relates to a corrugated pipe connecting device in an automobile fuel tank fuel-steam transport system, which comprises a joint, a corrugated pipe and a sealing ring. One end of the joint is arranged at the end of one side of the corrugated pipe; the sealing ring is arranged between the joint and the corrugated pipe; corresponding positions of the outer circumference of the sealing ring and the inner circumference of the corrugated pipe are in a 'bayonet' sealing structure; and the outer circumference of the joint is inserted into the inner circumference of the sealing ring. The corrugated pipe connecting device has the advantages of excellent pressure bearing capacity, vibration resistance, internal pressure pulse stability and capability of realizing rapid connection.
Description
Technical field
The utility model relates to bellows in a kind of automotive oil tank fuel-steam transporting system, relates in particular to this bellows linkage structure.
Background technique
Bellows is used in aerating system by automobile factory by means of advantages such as good mutabililty, noise abatement, damping are more and more, but bellows is perplexing main engine factory with being connected of other parts always.As use quick inserting joint to carry out the transition connection, and then cost is higher, and the too high difficulty of size requirement to adversary's part realizes simultaneously.
How bellows of design and fittings body bindiny mechanism are that the technician will consider in the automotive oil tank fuel-steam transporting system of automatic gearbox of vehicles.
Summary of the invention
The utility model technical issues that need to address have provided corrugated pipe connecting device in a kind of automotive oil tank fuel-steam transporting system, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: fittings body and bellows; Described fittings body one end is at a side end of bellows; Also comprise: a seal ring; Described seal ring is between fittings body and bellows; The internal diameter corresponding position of the external diameter of described seal ring and bellows is " bayonet socket " sealing configuration; The external diameter of described fittings body inserts described internal diameter of the seal ring.
Compared with prior art, the beneficial effects of the utility model are: have fabulous bearing capacity, vibration resistance and internal pressure pulse stability, and can realize connecting fast.
Description of drawings
Fig. 1 is a blast structural representation of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
By Fig. 1, Fig. 2 as seen: the utility model comprises: fittings body 1 and bellows 2; Described fittings body 1 one ends are at a side end of bellows 2; Also comprise: a seal ring 3; Described seal ring 3 is between fittings body 1 and bellows 2; The internal diameter corresponding position of the external diameter of described seal ring 3 and bellows 2 is " bayonet socket " sealing configuration 31; The external diameter of described fittings body 1 inserts described seal ring 3 internal diameters.
Described bellows 2 materials are nylon 12 (PA12); Sealing ring material is hydrogenated butyronitrile (HNBR), and the fittings body material is polyethylene (PE).
The utility model is mainly used mainly and is used in automotive oil tank fuel-steam transporting system.
The utility model has 3 parts and forms: be respectively fittings body, seal ring and bellows, the product schematic representation is seen Fig. 1 before the assembling.During assembling, the corrugated tube end of earlier seal ring being packed into is realized the sealing of seal ring and bellows.Then fittings body is inserted in the seal ring, fittings body causes the distortion of seal ring, thereby realizes the assembly sealing.Assembling back product schematic representation is seen Fig. 2.
The utility model bellows material is PA12, and sealing ring material is HNBR, and the fittings body material is PE.Above-mentioned material all has good oil resistance, can be used as long-term fuel delivery and uses.The seal ring amount of deformation need surpass 1mm, could realize better seal.
The utility model can be realized not leaking more than the internal pressure 5bar, and the assembly pull-out force is not less than 300N.Have fabulous bearing capacity, vibration resistance and internal pressure pulse stability etc.
