Description
Technical field
The utility model relates to a kind of roll-over valve proving installation, especially a kind of proving installation that is used to test roll-over valve protection pressure.
Background technology
Gasoline is volatile fuel, and therefore, the fuel oil in the fuel tank of automobile can volatilize very soon increases the pressure of fuel tank internal, when pressure arrives certain value, will produce certain danger.In order to address this problem, people can connect a canister on the fuel tank of automobile, and canister inside is filled by the very strong activated charcoal of adsorbability; Fuel-steam unnecessary in the fuel tank no longer is discharged in the atmosphere, but is incorporated in the canister by a snorkel, makes the active carbon adsorption fuel-steam; In the time of start; The solenoid valve of canister is opened in good time, and the fuel-steam that absorbs is imported inlet manifold again, to reach the purpose of practicing thrift fuel oil and environmental protection.
Along with the development of society, the security of automobile is more and more paid close attention to by people.Thereby the fuel oil entering snorkel for fear of inclination of vehicle is perhaps translated in the rear fuel tank is blasted; The upset safety protective valve need be set on snorkel; Be called for short roll-over valve or Tipping valve; When angle that fuel tank tilts certain, roll-over valve will be closed automatically, prevents that fuel oil from getting into snorkel and blast.
Flip angle is two important performance parameters of roll-over valve with protection pressure; What angle that the former has determined roll-over valve to tilt at mailbox makes works; The latter then can prevent vehicle in motion fuel oil get into canister because of rocking through snorkel, roll-over valve only just can be opened under certain pressure.
In order to ensure the effect of roll-over valve, need carry out the test of performance parameter to it through certain proving installation.There is more proving installation to can be used for test at present to flip angle, for example: disclosed on the Chinese patent document " the complete white dynamic test platform of Tipping valve ", its application publication number is CN102313644 A; This device is installed scrambler on the scrambler mount pad, motor is installed on motor mount, and two bearing seats are set between scrambler mount pad and motor mount; On bearing seat, be rotatablely equipped with the clamp body pedestal; Clamp body pedestal two ends have rotating shaft, and the input shaft of scrambler mount pad is connected with the rotating shaft of clamp body pedestal through the connecting shaft cover, and the output shaft of motor is connected with the rotating shaft of clamp body pedestal through shaft coupling; The Tipping valve clamp body is installed in the clamp body pedestal; Sidewall at the clamp body pedestal is fixed with revolving cylinder, on revolving cylinder, is fixed with to compress cylinder, is fixed with compact heap on the cylinder compressing; On compact heap, be provided with device for dotting, be provided with Tipping valve test air inlet tube in the bottom of clamp body pedestal.This device is simulated the actual working environment of roll-over valve through rotating mechanism of driven by motor, accomplishes the detection to roll-over valve, makes testing result more near reality.But it mainly is applicable to the flip angle of test roll-over valve, and whole mechanism is complicated.But, still there is not at present a kind of special test device of simple and reliable for structure, convenient test for the test of protection pressure.
The utility model content
