Embodiment
Fig. 1-12 shows urea box assembly 10.This urea box assembly comprises the urea box 12 with inner space.This urea box 12 is formed by middle-high density polythene or other suitable material that can bear the urea liquid corrosion.Filler seal with buss circle 13, filler lid supporting element seal ring 17, filler lid seal ring 50 and urea liquid exit seal circle 28 are made by the good airproof performance and the suitable material that can bear urea liquid.Filler lining 14, filler lining bolt 15, filler lid supporting element bolt 18 and filler lid 19 are made by the suitable material that can bear urea liquid.Filler lid supporting element 16, bayonet lock 20, vent valve nut 34, urea liquid outlet nut 32 and urea liquid outlet bolt 30 are made by the suitable metallic material that can bear urea liquid.Vent valve 36 can bear the suitable material of urea liquid and make.
The position of filler 12b is lower than the extreme higher position point 12c of urea box 12, and make urea box after filling with urea liquid, the space more than 6% of the urea liquid volume of still filling with to some extent in the urea box is empty, required expansion space when freezing at low temperatures as urea liquid that is to say that filler 12b puts solution in the urea box between the 12c to the extreme higher position volume 36 is filler 12b to 6% of the volume 34 of the interior solution of the urea box between the urea box nadir 12n at least.Urea box is no more than 20% of the maximum cross-section area in the maximum area and the difference between the minimum area of the cross section 22 that (between urea box bottom 12a and the filler 12b) on the short transverse is made of urea box inwall 12p so that the volume of urea box (between urea box bottom 12a and filler 12b) with highly near linear relationship.
The bottom of urea box 12 extends outward a step cutting pattern 38, and has a through hole 12j on this step 38, be embedded with a urea liquid outlet nut 32 on the described through hole 12j, in order to urea liquid outlet bolt 30 and urea liquid exit seal bar 28 to be installed, be convenient to regular clean and maintenance urea box.
Urea box 12 has a circular filler step 37, and filler lid supporting element 16 and filler lining 14 are installed on the filler step 37; Filler lid supporting element bolt 18 is fixed in filler lid supporting element 16 and filler lid supporting element seal ring 17 on the urea box 12, and filler lining bolt 15 is fixed in filler lining 14 and filler seal with buss circle 13 on the urea box 12.Filler lid 19 is tightened against filler lid supporting element 16 with rotation mode; Several claw 19b on the filler lid 19 are in order to fixing filler lid seal ring 50, and seal ring 50 plays the effect of sealing urea liquid.
An embedded vent valve nut 34 on the urea box 12, in order to vent valve 36 to be installed, the rigging position of vent valve 36 is not less than the position of filler 12b, is beneficial to low pressure ventilation in the urea box.
The triangle muscle 12f that has the triangle muscle 12d of several vertical directions and/or several substantially horizontals on the urea box 12 is to improve the rigidity of urea box, also to comprise on the urea box 12 the muscle 12g that the groove type muscle 12e that can Gong install and use and buffering urea liquid vibrate.
In actual use, after elder generation is installed in the liquid level sensor assembly on the urea box 12, again urea box assembly 10 is installed on the car load.When prepare adding urea liquid, rotation filler lid 19 earlier, filler lid step 19a when flange 16a rotates to breach 16b, filler lid 19 is taken off, begin to add urea liquid then.After filling it up with urea liquid, cover filler lid 19, and filler lid step 19a is rotated to flange 16a from breach 16b, with locking filler lid 19.In car running process, urea liquid continues to be extracted from urea box 12, so the liquid level of urea liquid continues to descend.Like this since the urea liquid volume in this utility model and the liquid level of urea liquid near linear relationship, so remaining urea liquid volume will correctly be presented on the automobile instrument panel.
To sum up, the utility model encyclopaedizes by the above embodiments.But the utility model is not intended to be defined in the content of the foregoing description.Under the situation that does not break away from spirit and scope of the present utility model, urea box assembly of the present utility model can have many different distortion.For example urea box 12 can have different the variation.The plane that vent valve 36 is installed on the urea box 12 also can be a curved surface.Filler lid 19 can have different curvedization with filler lining 14.For example, change angle of inclination or improve these parts according to new country or international standard; Also can be embedded in several nuts with installation filler lid 19 at urea box 12 as required, or the like.
