Abstract

本实用新型涉及一种汽车尿素罐的零部件，尤其涉及一种尿素灌加注颈总成。一种尿素灌加注颈总成，包括上端管口外翻的管状加注颈；所述加注颈的下端外部套设一个管状过滤网；所述过滤网的封闭下端底部向上凸起呈圆锥状。安装过滤网，过滤效果优良，而且生产加工简单，过滤网底部为锥形，降低了液体的冲击力，使得尿素液体及时向四周流出，加注更顺畅；O型密封圈有效防止尿素外溢。

Description

一种尿素灌加注颈总成
技术领域
本实用新型涉及一种汽车尿素罐的零部件，尤其涉及一种尿素灌加注颈总成。 
背景技术
汽车的尿素罐主要安装在卡车上，加入尿素，经过发动机循环，用以控制排放达到国家标准。尿素罐的加注口用以向尿素罐内加注尿素，常用的尿素加注口，多为管状，管壁上设置通孔，起到过滤作用，底部为平底，加注尿素时，液体对平底冲击力较大，进而导致尿素液流出不及时致使加注口内液位急速上升，导致尿素加注不畅。 
实用新型内容
本实用新型提供了一种尿素灌加注颈总成，利用其给尿素罐加注尿素稳定顺畅。为了实现上述发明目的，本实用新型采用了以下技术手段： 
一种尿素灌加注颈总成，包括上端管口外翻的管状加注颈；所述加注颈的下端外部套设一个管状过滤网；所述过滤网的封闭下端底部向上凸起呈圆锥状。 
所述过滤网通过螺钉固定设置在加注颈的上端翻口上； 
所述过滤网和加注颈的接缝转角处设置有O型密封圈。 
本实用新型的有益效果在于：安装过滤网，过滤效果优良，而且生产加工简单，过滤网底部为锥形，降低了液体的冲击力，使得尿素液体及时向四周流出，加注更顺畅；O型密封圈有效防止尿素外溢。 
附图说明
图1为本实用新型一种尿素灌加注颈总成的结构示意图。 
具体实施方式
下面结合附图，对本实用新型一种尿素灌加注颈总成的优选实施方式作出详细的描述： 
如图1所示，本尿素灌加注颈总成主要包括加注颈1，加注颈1主体为圆管状，其上端管口外翻。加注颈1的下端外部套设一个过滤网4，过滤网4整体也为圆管状，下端封闭，上端管口也是外翻结构，其内径尺寸与加注颈1外径尺寸相适应。加注颈1与过滤网4的外翻管口用螺钉2固定连接在一起，从而将过滤网4固定套设在加注颈1下端。安装过滤网4，加注口的过滤效果优良，而且生产工艺简单，降低了生产成本。 
过滤网4的封闭下端底部向上凸起呈圆锥状。加注尿素时，降低了液体对过滤网4底部的冲击力，并使得尿素液体及时向四周流出，尿素加注更顺畅。 
加注颈1与过滤网4的接缝拐角处设置有O型密封圈3，有效防止了尿素外溢。 

Claims (3)
