Abstract

一种胶套密封水龙头,特别是这种水龙头具有可调节的密封结构,它可以全部由硬质塑料制造,阀体与阀芯之间有胶套,具有较低的制造成本和不锈蚀特点;这种水龙头具有可调节的密封工作面,所以有启闭灵活,密封可靠之优点;另外这种水龙头的阀芯与阀体之间有胶套,中间有水润滑,很少磨损,具有较长的使用寿命。

Description

胶套密封水龙头
本实用新型涉及一种水龙头,特别是这种水龙头的可调性密封。
已有的技术中,水龙头的结构多为两种形式,一是螺杆传动压紧口盖,二是阀体与阀芯直接配合的换向型,这两种结构都容易在相互转动的配合面上造成磨损,而产生渗漏,减少使用寿命。
本实用新型为克服上述不足,提出一种内有密封胶套,且可调节密封面松紧度的胶套密封水龙头。
胶套密封水龙头有阀体,阀体内有胶套,胶套内有阀芯,阀芯的上端有搬杠,其特点是阀体的内腔是上小下大的圆锥孔,圆锥孔小端有台阶,台阶上有缺口,胶套为圆锥形,小端的端面上有凸台,胶套装在阀体内腔,胶套上的凸台装配在阀体上的缺口中,用于防止胶套在阀体内转动;阀芯安装在胶套内,阀芯外表中部是圆锥面,与胶套的内圆锥面相配合,阀芯有内腔,阀芯圆锥面上有对称分布的大小两个通水孔,用于改变出水量和阀芯与胶套间润滑;阀芯的上端有径向长方孔,用于穿入搬杠,搬杠与阀体之间有垫圈,搬杠的窄面有锥度,小端有螺钉用于防止搬杠滑落,搬杠的锥面与长方孔的上斜面相配合,串动搬杠可调节阀芯与胶套间的松紧度,转动搬杠即转动阀芯,可启闭水龙头,阀芯下部是出水口,外部有螺纹连接防溅淋头。
本实用新型胶套密封水龙头比已有的水龙头有如下益处:一是它可全部由塑料制造,具有较低的制造成本和不锈蚀性,有较长的使用寿命。二是它有可调节的密封工作面,可使配合面的松紧度保持最佳状态,以保证可靠的密封和启闭动作灵活。三是它的阀体与阀芯之间有胶套,改硬对硬的工作面配合为胶对塑的弹性配合,使其增加了密封性能。
下面结合附图对本实用新型作进一步说明。
图1是胶套密封水龙头的主剖视图。
图2是图1的A-A剖视图。
附图中有阀体1、阀芯2、胶套3、搬杠4、垫圈5、螺钉6、防溅淋头7。阀体1上有螺纹11连接水管,阀体1的内圆锥面安装胶套3,胶套3的小端有两个凸台31,安装在阀体1上部的缺口中,防止胶套3在阀体1内转动,阀芯2安装在胶套3中,阀体1、阀芯2、胶套3上都有水的通孔12,转动搬杠4可启闭水龙头,水经过通孔12进入阀芯2的内腔21,再经出水口22流出,阀芯2的上部有长方孔23,孔内穿有搬杠4,搬杠4的窄面41有锥度,与长方孔23的上面配合,串动搬杠4可使阀芯2做轴向微动,实现调节阀芯2与胶套3之间的松紧度;搬杠4小端有螺钉6,搬杠4与阀体之间有垫圈5,用于防止搬杠4与阀体1直接摩擦,阀芯2上有一小孔24,用于改变出水量和配合面润滑,出水口22外部有螺纹连接防溅淋头7。
