Description

A kind of urea tank air-leakage test mechanism
Technical field
The utility model relates to a kind of air-leakage test mechanism, is specifically related to a kind of urea tank air-leakage test mechanism.
Background technology
Urea tank, i.e. urea storage tank, be mainly used in being arranged on truck, load onto urea, and tail gas is through cycle of engine, and discharge just reaches state IV standards.Be about to need to use aqueous solution of urea in the state four of enforcement, Ou Si emission standard diesel emission abatement system, this urea tank is used for stored urea aqueous solution, SCR selective reduction, reduces oxides of nitrogen.
After urea tank needs to fill aqueous solution of urea, tail gas just can be discharged in air after urea tank, and therefore the impermeability of corresponding urea tank requires higher, requires that urea tank is water-tight, air tight.In testing process in the past, mostly be and manually blocked successively by three of urea tank tank mouths, then inflate in urea tank, around tank mouth position, sprinkle water, whether manual observation tank mouth has bubble with this to differentiate the impermeability of urea tank.
Utility model content
For there being the defect of technology on overcoming, the purpose of this utility model is intended to proposition can detect the bubble-tight a kind of urea tank air-leakage test mechanism of tank body automatically.
For achieving the above object, the utility model adopts following technical scheme:
A kind of urea tank air-leakage test mechanism, comprising and detects dolly, water vat, it is characterized in that: the workbench of described detection dolly is placed for detecting bubble-tight water vat; A fixed bar is fixed in described water vat inside; The middle part of described fixed bar is provided with slide rail; Described fixed bar is provided with two be horizontally disposed with, can the flexible metal strip of movement on slide rail; Described flexible metal strip is connected by locking head with between slide rail; One end of described flexible metal strip is fixed with can by the rubber closure of urea tank Jar opening sealer; The workbench that dolly is detected in the side of described water vat namely places one and fills dual-purpose pump of bleeding; The described dual-purpose pump of bleeding that fills is connected to by pipeline the gas port that rubber testing covers; Described rubber testing covers and has gas port and fix a moisture responsive rod; The top of described rubber testing lid arranges an alarm lamp.
Explanation and the further scheme of such scheme are as follows:
In such scheme, described in fill on pipeline that dual-purpose pump of bleeding is connected with rubber testing lid an air valve be set.
In such scheme, described rubber seal covers and arranges the pressure gauge that can survey urea box internal air pressure.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Whether the utility model not only can carry out bleeding and use the induction of moisture responsive rod to leak, and inflatable also directly can be used to observe the gas leakage situation of urea tank in water, can carry out the air tight test of various ways.The structure of whole testing agency is simple simultaneously, conveniently moving, can be suitable for multiple place and be suitable for.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In above accompanying drawing: 1, detect dolly; 2, water vat; 3, workbench; 4, fixed bar; 5, slide rail; 6, flexible metal strip; 7, locking head; 8, rubber closure; 9, dual-purpose pump of bleeding is filled; 10, gas port; 11, moisture responsive rod; 12, alarm lamp; 13, air valve; 14, pressure gauge; 15, rubber testing lid; 16, urea tank.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in Figure 1:
A kind of urea tank air-leakage test mechanism, comprising and detects dolly 1, water vat 2, the workbench 3 of described detection dolly 1 being placed for detecting bubble-tight water vat 2; A fixed bar 4 is fixed in described water vat 2 inside; The middle part of described fixed bar 4 is provided with slide rail 5; Described fixed bar 4 is provided with two be horizontally disposed with, can the flexible metal strip 6 of movement on slide rail; Described flexible metal strip 6 is connected by locking head 7 with between slide rail 5; One end of described flexible metal strip 6 is fixed with can by the rubber closure 8 of urea tank Jar opening sealer; The workbench 3 that dolly 1 is detected in the side of described water vat 2 namely places one and fills dual-purpose pump 9 of bleeding; The described dual-purpose pump 9 of bleeding that fills is connected to gas port 10 on rubber testing lid 15 by pipeline; Described rubber testing lid 15 have gas port 10 and fix a moisture responsive rod 11; The top of described rubber testing lid 15 arranges an alarm lamp 12; Described filling on pipeline that dual-purpose pump 9 of bleeding is connected with rubber testing lid 15 arranges an air valve 13; Described rubber closure 8 is arranged the pressure gauge 14 that can survey urea box internal air pressure.
The urea tank 16 of having produced is placed in water vat 2, rubber closure 8 in two flexible metal strip 6 is covered the air intake opening in urea tank 16 and liquid level gauge mouth, flexible metal strip 6 regulates fixed position on slide rail 5, locking locking head 7, flexible metal strip 6 is fixed on fixed bar 4, then rubber testing lid 15 is blocked gas outlet, moisture responsive rod 11 on rubber testing lid 15 stretches in urea tank 16, open air valve 13, fill dual-purpose pump 9 of bleeding, air in urea tank 16 is extracted out, observes pressure gauge 14 and keep the suitable speed of exhaust.If urea tank 16 exists gas leakage seepy question, then the water in water vat 2 will enter in urea tank 16 from the gap of urea tank 16, and moisture responsive rod 11 senses in urea tank 16 have moisture, then alarm lamp 12 is reported to the police.Then rubber closure 8 is covered liquid level gauge mouth and gas outlet, rubber testing lid 15 is covered air intake opening, repeat above detecting step.Detect the tightness of each tank mouth successively.
Dual-purpose pump of bleeding is filled owing to using, also inflation in urea tank can be thought, urea tank is immersed in water vat, the situation of artificial observation urea tank in water, whether observe has bubble to produce, but because the gas leakage point of urea tank is all less, may observe bubble does not have the precision of above-mentioned moisture responsive rod high.
The utility model main body supporting body is for detecting dolly, and conveniently moving can carry out air-leakage test at various production station to urea tank, and testing agency has Through Several Survey Measure simultaneously, alternative more, decreases artificial malobservation.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection domain of the present utility model.
