Abstract

一种柔性球阀与阀体锥孔斜面相切密封水龙头, 其由手柄、锁紧母、压盖、丝杠、阀体和阀芯等组成,其 特征在于:阀体的锥孔与丝杠端部的挡肩之间设置了 一个柔性球阀。采用柔性球锥面封水方式,操作力 小,封水性能好,结构简单,维修方便,零件不易磨损, 使用寿命长。

Description

本实用新型涉及水龙头,特别是一种柔性球阀与阀体锥孔斜面相切密封水龙头。
传统的水龙头或阀门,均采用棱线式封水方式,即通过旋转丝杠,使其下端的铜垫挡肩挤压橡胶垫与封水口棱突挤压封水,因橡胶垫薄,又为死点接触,反复的摩擦、挤压,橡胶垫很快就被割断,不易更换,再则铜垫挡肩与轴线不垂直或挡肩平面度差都会造成密封不严,因此传统产品封水性能差,操作力大,零件易磨损,使用寿命短。
本实用新型的目的在于提供一种柔性球阀与阀体锥孔斜面相切密封水龙头或阀门,以提高其封水性能,减化生产工艺,减小操作力,方便维修,延长使用寿命。
本实用新型由手柄1、锁紧螺母2、压盖3、丝杠4、阀体5、阀芯6等部件组成,其特征在于:所述的阀体5的进水孔为锥孔,阀芯6为一个柔性球阀,该柔性球阀与阀体5的锥孔斜面相切;所述的丝杠4端部设置有一个内球面的挡肩,挡肩的内球面与柔性球阀吻合。
以下结合附图进一步描述。
图1为其结构示意图,图2为其阀芯密封部位局部放大图。
如图1所述的水龙头只有六个零件组成,它们分别为:手柄1、锁紧螺母2、压盖3、丝杠4、阀体5、阀芯6。图2示出了其阀芯密封部位相应零件结合情况,详见上文,此处不再赘述。
组装时,将丝杠4装入压盖3中,压盖3上端装入密封毡圈和锁紧螺母2,丝杠2端部装手柄1,最后将装好的压盖整件拧紧在已装有柔性球阀6的阀体5上,即装配完毕,轻轻拧使柔性球阀6和阀体5的进水锥孔如图2所示结合即可封水。
上述的柔性球阀可以是橡胶球、柔性塑料球及其它材料制作的具有弹性的球。
本实用新型优点如下:
采用柔性球锥面封水方式,因柔性球有弹性,只要施加很小的压力,球即和锥孔紧密相切,封水性能好,而且球受水流的冲击,随时可变换体位,避免了局部压伤,球面利用率高,更换方便。结构简单,零件较传统产品少,制造工艺简化,成本低,操作力小,零件不易磨损,使用寿命大大延长。
