Description
Technical field
The utility model relates to auto parts and components field, particularly a kind of urea tank air tightness test-bed.
Background technology
Impermeability is very high for the technical requirement of urea tank, once urea tank is leaked, urea liquid can be caused to spill, and evaporates into the ammonia that smell is pungent, and causing after-treatment system to lose efficacy cannot carry out effecting reaction to tail gas simultaneously, causes discharge to exceed standard.Therefore, before urea tank is dispatched from the factory, all air-leakage test will be carried out.
At present, existing urea tank air tightness detection equipment adopts traditional bubbling method, staff needs urea tank to be fixed in the sink with manual, then pressurize in tank with air gun, observe urea tank periphery whether have Bubble simultaneously, and will judge its leak degree according to number of bubbles, operator's working strength is large, easy fatigue, easily causes undetected.
Summary of the invention
In order to solve the problem of prior art, it is large that the utility model embodiment provides the existing air-tightness detection device working strength of a kind of solution, the urea tank air tightness test-bed of the problem of complex operation.Described technical scheme is as follows:
The utility model embodiment provides a kind of urea tank air tightness test-bed, and described urea tank air tightness test-bed comprises source of the gas, gas-holder, pneumatic triple piece, pressure regulator valve, total solenoid valve, way solenoid valve, tensimeter, ball valve, urea box, sound suppressor, pressure transducer, electric cabinet;
Described gas-holder import is communicated with described source of the gas, described reservoir outlet and described pneumatic triple piece inlet communication, described pneumatic triple piece outlet and described pressure regulator valve inlet communication, described pressure regulator valve outlet and described total solenoid valve inlet communication, described total electromagnetic valve outlet respectively with each described way solenoid valve inlet communication, each described branch road electromagnetic valve outlet and each described urea box inlet communication, each described urea box outlet and each described ball valve inlet communication, each described ball valve outlet is communicated with each described tensimeter;
Described total solenoid valve is connected with described electric cabinet, each described way solenoid valve one end is all connected with described electric cabinet, each described branch road electromagnetic valve outlet is all communicated with described sound suppressor, and each described ball valve one end is all communicated with described pressure transducer, and described pressure transducer is connected with described electric cabinet.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
Thering is provided robotization dry type to detect air tightness test-bed, for detecting urea tank, solving existing air-tightness detection device working strength large, the problem of complex operation.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the urea tank air tightness test-bed that the utility model embodiment provides.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.

The utility model embodiment provides a kind of urea tank air tightness test-bed, see Fig. 1, described urea tank air tightness test-bed comprises source of the gas 1, gas-holder 2, pneumatic triple piece 3, pressure regulator valve 4, total solenoid valve 5, way solenoid valve 6, tensimeter 7, ball valve 8, urea box 9, sound suppressor 10, pressure transducer 11, electric cabinet 12;
Gas-holder 2 import is communicated with source of the gas 1, gas-holder 2 exports and pneumatic triple piece 3 inlet communication, pneumatic triple piece 3 exports and pressure regulator valve 4 inlet communication, pressure regulator valve 4 exports and total solenoid valve 5 inlet communication, total solenoid valve 5 export respectively with each way solenoid valve 6 inlet communication, each way solenoid valve 6 exports and each urea box 9 inlet communication, and each urea box 9 exports and each ball valve 8 inlet communication, and each ball valve 8 outlet is communicated with each tensimeter 7;
Total solenoid valve 5 is connected with electric cabinet 12, and each way solenoid valve 6 one end is all connected with electric cabinet 12, and each way solenoid valve 6 exports and be all communicated with sound suppressor 10, and each ball valve 8 one end is all communicated with pressure transducer 11, and pressure transducer 11 is connected with electric cabinet 12.
Source of the gas reaches and arranges inner gas pressure after gas-holder, pneumatic triple piece and pressure regulator valve, then controlled to inflate to corresponding urea tank by electric cabinet, detect the pressure sensor signal be connected with urea tank, inflation is stopped when urea tank reaches setting value, pressurize is carried out according to setting-up time, dwell time terminates the force value inside rear detection urea tank, reduces degree judge that whether the impermeability of detected urea tank is qualified according to manometric force value.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
Thering is provided robotization dry type to detect air tightness test-bed, for detecting urea tank, solving existing air-tightness detection device working strength large, the problem of complex operation.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
