The utility model solves above-mentioned technical matters by following technical proposals:
A kind of expansion tank, for in vehicle fuel delivery system, described expansion tank comprises a tank body, one cover, two connectors, its feature is, described tank body comprises a tank base, one tank wall, described cover comprises a cover top, one cover sidewall, described cover is linked in described tank body, and the outside face of described cover sidewall and the inside face of described tank wall are affixed merga pass welded seal to be connected, described tank wall is provided with two relative outer perforation, described cover sidewall is provided with two relative interior perforation, described outer perforation is relative one by one with described interior perforation, described connector is located in described outer perforation and described interior perforation successively.
Preferably, the height of described tank wall equals the height of described cover sidewall.
Preferably, described cover top is provided with one with the junction of described cover sidewall and is connected chamfering, and described connection chamfering is connected by welded seal with described tank wall.
Preferably, described outer perforation comprises the extension that the first through hole and be located on described tank wall protrudes from described tank wall, and the internal diameter of described extension is equal with the external diameter of described connector.
Preferably, described interior perforation comprises the peristome that the second through hole and be located on described cover sidewall extends to the bottom of described cover sidewall from described second through hole, and the width of described peristome and the external diameter of described connector match.
Preferably, described connector is slub type.
Preferably, described connector is connected by welded seal with described outer perforation.
Preferably, each described connector is also provided with a seal groove with described outer one end be connected of boring a hole, and a seal ring and described seal groove are tightly connected.
A kind of vehicle fuel delivery system, its feature is, it comprises expansion tank as above.
In the utility model, above-mentioned optimum condition can combination in any on the basis meeting this area general knowledge, obtains each preferred embodiment of the present utility model.
Positive progressive effect of the present utility model is: compared with prior art, expansion tank of the present utility model has fabulous bearing capacity, the ability that abates the noise and internal pressure pulse stability, can realize the following No leakage of internal pressure 30Mpa, and after the assembling of actual car load, noise obviously reduces and does not even have noise.
