Abstract
本发明公开了一种复合水龙头阀体,整个阀体包括填充体、内壳体和外壳体;所述填充体内设置有进水管和出水管;所述内壳体包裹在填充体外,内壳体由左、右两瓣合为一体而成;所述外壳体一体生成,外壳体上设置有阀芯座结构。本发明阀体的制造材料结合多种材料,在降低材料制造成本的同时保证了本体的强度和成品的光泽度,同时也保证了产品加工的良品率和成品质量,提升了生产效率。
Description
本发明涉及一种水龙头,特别是涉及一种复合水龙头阀体。
最早的水龙头其阀体材料一般都采用不锈钢、铜或铜合金等金属材料,优点是成品的光泽度很好、强度高、不易磨损,缺点是材料成本太高,制造次品率比较高,本体制造的模具采用砂型并一体制造,在制造过程中很容易出现砂眼和毛孔。
为此,近年来出现了很多采用非金属材料制造的水龙头,如陶瓷水龙头、塑料水龙头、树脂水龙头等,这几种方式在相比传统龙头阀体在一定程度上都降低了材料的制造成本。
而为了进一步降低材料成本,目前市面上又出现了一种多种材料复合的水龙头,其结构一般包括外壳体和填充体,填充体中设置进水管和出水管,其中的外壳体采用塑料、树脂或金属,填充体为水泥、石膏等,在此,因填充体的材料非常经济,该结构设计的外壳体保证了产品外表的光洁度,而填充体结构则进一步降低了龙头阀体的材料成本。以上复合水龙头的加工过程是:首先用模具一体制成带进、出水管的填充体,而后在加工完成的填充体外壁注塑或金属铸造水龙头外壳体,最后再对水龙头外壳表面进行电镀或真空镀膜的光洁处理。但在实际加工当中,当对加工完成的填充体外壁进行注塑或金属铸造外壳体时,填充体的温度很高,而填充体本身具有一定的膨胀率,由于其表面无保护层结构,导致填充体受热后很容易发生爆裂,加工的次品率很高,严重影响了生产效率和成品质量。
针对上述问题,本发明设计了一种复合水龙头阀体,其阀体的制造材料结合多种材料,在降低材料制造成本的同时保证了本体的强度和成品的光泽度,同时也保证了产品加工的良品率和成品质量,提升了生产效率。
为实现上述目的,本发明采用以下技术方案:
一种复合水龙头阀体,其特征在于:整个阀体包括填充体、内壳体和外壳体;所述填充体内设置有进水管和出水管;所述内壳体包裹在填充体外,内壳体由左、右两瓣合为一体而成;所述外壳体一体生成,外壳体上设置有阀芯座结构。
上述内壳体底部设置有浇口,浇口旁边设置有浇注排气孔。
上述填充体由非金属材料所制成。
上述非金属材料包括水泥、泥沙、塑料、树脂、碳酸钙、石膏、矿石粉或磁性材料。
上述内壳体由塑料或金属制成。
上述外壳体由塑料或金属制成。
上述塑料包括PP、PP改性材料、ABS、ABS改性材料、PPS、PEO、PVC、PA、PPR、PET或PC材料。
上述金属包括铜、铜合金、铝、铝合金、锌合金或铸铁。
上述复合水龙头阀体的制造方法,其步骤如下:a、首先通过模具注塑或金属铸造出内壳体的左右两瓣;b、把进水管和出水管定位在内壳体左、右两瓣的任意一瓣上,而后把左右两瓣用塑封或焊接合为一体;c、从内壳体底部的浇口外往内壳体内灌注填充体,直到填充体完全填满整个内壳体;d、把形成一体的内壳体和填充体作为嵌件放入外壳体模具的模腔中,而后在内壳体外壁注塑或金属铸造出带阀芯座的外壳体;e、最后对外壳体进行抛光、电镀或真空镀膜表面处理即得成品水龙头阀体。
本发明阀体结合多种材料制作,在保证同强度、同光泽度的情况下大大降低了材料成本。同时为便于加工,提升产品良品率和成品质量,整个阀体由外壳体、内壳体和填充体组成,在加工时,首先由内壳体和填充体形成阀体毛坯,而后再在内壳体外壁进行注塑或金属铸造得到外壳体,在此,因阀体毛坯由内壳体包裹填充体形成,内壳体相当于给填充体设置了一保护层,有效解决了填充体的受热膨胀爆裂问题,进而保证了产品加工的良品率,提升了成品质量和加工效率。
