Abstract

推拉式自来水阀门,在连有手柄的阀杆另一端紧 靠凸沿下装有截锥形密封塞,密封斜面与相应部位的 阀体相接触,关闭时阀杆凸沿之间的凹部位于出水口 部位,阀体入水口端有可容纳且大于密封塞的空腔, 另一端的阀杆上套有形环压盖,压盖侧壁与阀体连 接,压盖底部装密封圈。
本实用新型开关迅速,注量可任意调节,开启后 无需手继续按压,斜面密封较平面密封效果显著,结 构简单,维修方便。

Description

本实用新型属于自来水阀门,特别是一种阀杆在阀体内作往复运动的推拉式自来水阀门。
现有的用于民用、公共设施及管路的水阀中,大多采用手轮旋转关闭式,不但旋转费事,而且密封方式与水流方向相反,在阀杆顶端旋转部位和水咀处容易浅露;还有一种按动式水阀,阀体中的阀杆下面装有密封活塞,活塞下连接有弹簧,弹簧与活塞的活动部位与出水口相通,通过按动手柄由阀杆带动活塞压缩弹簧,使水流出,其缺点是在连续用水时,手不能脱离手柄,不便使用,阀体内弹簧易生锈变形。
本实用新型的目的在于克服上述水阀存在的缺陷,提供一种开关迅速且开启后无需手继续按压,密封效果好,维修简便的推拉式自来水阀门。
本实用新型是在带空腔的阀体内设置有可作往复运动的阀杆,在阀体的一端和侧面分别是入水口和出水口,在阀体另一端连有手柄的阀杆滑动部位装有
Figure 902078038_IMG4
形环压盖,压盖侧壁与阀体连接,压盖底部装有密封圈,在出水口的阀杆凸沿下装有截锥形密封塞,密封斜面与阀体接触起到密封作用,关闭阀时,阀杆凸沿之间的凹部与出水口部位相对。
当按动手柄时,阀杆向一方滑动,阀杆上的截锥形密封塞斜面脱离与阀体为接触面并到达虚线位置,水经入口通过密封塞外围及阀杆凹部流出。当向相反方向拉动手柄时,阀杆带动密封塞复位,堵住入水空腔口,水流停止。此时有浅露可能的只是密封塞斜面与阀体相应接触部位,而入水口水流方向与密封塞的密封方向一致,水流对密封塞产生的压力进一步加强了密封效果,同时手柄与出水口不在同一位置,避免了推拉部位对水的污染。在更换压盖下部的密封圈时,不必关闭水阀,可将连在阀杆上的手柄取下,旋出压盖,将新垫套入阀杆重新旋紧压盖和手柄即可。水流量调节可通过选择阀杆在阀体中的推拉位置来实现。
下面通过附图对本实用新型作一详细描述。
附图为本实用新型的剖示图。
见附图,阀杆〔4〕位于带有与阀杆活动相适应的空腔阀体〔1〕内,阀杆一端连有手柄〔7〕,另一端凸沿〔9〕下套有倒截锥形密封塞〔3〕,截锥面紧靠凸沿的横截面,由旋在阀杆上的螺母〔2〕使密封塞固定。阀关闭时,阀杆〔4〕凸沿〔9〕之间凹部滑动到出水口〔10〕部位,阀开启时,阀杆凹部可增大水流空间。阀体一端为入水口〔8〕,经入水口有一可容纳且大于密封塞的空腔,阀体〔1〕另一端的阀杆〔4〕上套有 形环压盖〔6〕,使阀杆经压盖孔在阀体中滑动,压盖〔6〕侧壁的外螺纹与阀体内螺纹配合,压盖底部装有密封圈〔5〕,除起到密封作用外,还用来调节压盖与阀杆接触松紧度。密封塞和密封圈均由橡胶制成,阀体材质可采用硬质塑料。
