It can use to the urea tank for containing urea in SCR aftertreatment system, after urea tank uses a period of time, urinate at present
The bottom of plain tank will deposit the deposits such as some impurity, it is necessary to which timing tapping is cleaned, therefore is provided with the bottom of urea tank
Tap hole.Existing urea box tapping mouth structure is that metal insert is set on housing, has internal thread in metal insert inner circle, with
External screw thread matches on plug, puts sealing gasket on plug, is subsequently installed in metal insert and is tightened and ensure to seal.Due to structure
Reason metal insert anti-rotation ability, during dismantling or assembling plug, easily twisted off or unscrewed together；Due to sealing gasket
It is to be enclosed on the plug of screw-type structure, is easily lost during dismounting, causes to lose sealing function, cause leakage and crystallize.In addition,
, need to be using the inserts and plug of special material due to the corrosivity of urea, while tap hole structural manufacturing process is also more complicated, is manufactured into
This is higher.
Such as Chinese patent notification number：CN 105883168A, publication date：In August, 2016 patent of invention of 24 days discloses one
Kind of closure, including enclosing cover, the inner cap being engaged in enclosing cover with enclosing cover is arranged on, the outer edge of inner cap has concave part, groove
Fluid sealant is filled with portion, fluid sealant carries out sealing cooperation with bottle, and enclosing cover and/or interior cover are provided with relative the opposing party's projection
Lug boss.But the structural manufacturing process is also more complicated, manufacturing cost is higher, and anti-rotation ability, urea easily corrodes seal,
Cause sealing effectiveness bad, in-convenience in use.
The content of the invention
The purpose of this utility model is, sealing cover structure letter also more complicated for existing urea case tap hole structural manufacturing process
Single, anti-rotation ability, urea easily corrodes seal, causes sealing effectiveness bad, it is easy to the defects of revealing and crystallizing and
Deficiency, there is provided a kind of structural manufacturing process is simple, and anti-rotation kinetic force is good, improves decay resistance, good sealing effect, using very convenient
A kind of urea box tapping mouth sealing device.
To achieve the above object, technical solution of the present utility model is：A kind of urea box tapping mouth sealing device, bag
Urea box is included, the bottom of urea box is provided with tap hole, external screw thread is provided with the excircle of the tap hole, is set on tap hole
Blanking cover is equipped with, is provided with the internal thread being engaged with external screw thread on the inwall of blanking cover, the bottom of blanking cover is provided with bayonet socket, on bayonet socket
Sealing gasket is fixed with, sealing gasket faces the external port of tap hole.
The periphery of the blanking cover is arranged into nut head structure type, and blanking cover adopts made of plastic, the interior spiral shell inside blanking cover
Line is also plastic construction.
The sealing gasket is made of the elastomeric material of resistant to urea corrosion, and the diameter of sealing gasket is more than the external diameter of tap hole.
The beneficial effects of the utility model are：
1. the utility model is provided with external screw thread on the excircle of tap hole, it is provided with the inwall of blanking cover and external screw thread
The internal thread being engaged, structural manufacturing process are simplified, and anti-rotation kinetic force is good, and blanking cover is made of integral molded plastic, is not deposited
Having by the risk of urea corrosion.
2. the utility model is rational in infrastructure, blanking cover bottom is provided with bayonet socket, and bayonet socket can be effectively firmly solid by sealing gasket
The bottom of blanking cover is scheduled on, is not in the situation that sealing gasket is lost in use, while improves sealing property, it is corrosion-resistant
Property is fine, using very convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：Urea box 1, tap hole 2, blanking cover 3, external screw thread 4, sealing gasket 5, bayonet socket 6.
Embodiment
The utility model is described in further detail below in conjunction with brief description of the drawings and embodiment.
Referring to Fig. 1, a kind of urea box tapping mouth sealing device of the present utility model, including urea box 1, the bottom of urea box 1
