Abstract

该发明为自来水管道中的一种止水阀门,属建筑材料领域。本发明所采用的技术方案是:阀体内设一对对称L型槽内套,设一片止水板置于内套L型槽内,使止水板只能转动不能左右移动。设传压板及胶封分别各一对对称置于止水板两侧。胶封的两端分别与传压板及内套相连起密封作用。采用止水板及传压板之间的平面作止水面。止水板及传压板分别设有两个三角孔,使水只能经过两个三角孔通过。本发明的特殊功能是自动关闭,可防止住宅或公共场所,因忘记关闭水源,发生冒水现象。

Description

保险阀门
一、技术领域
该发明为自来水管道中的一种止水阀门,属建筑材料领域。
二、背景技术
就申请人所知,目前国内外市场上销售的普通止水阀门,常见为闸阀或球两种类型,这两种阀门均存在着不耐久现象。对国家专利局提供的(EPO453287)公开的一种阀门,本发明与其相比应有所不同是:内套所设计的L型槽,传压止水的胶封,开关的手柄,最突出特点是自动关闭功能,可防止住宅或公共场所因忘记关闭水源,所产生的自来水跑水现象,即节约了水资源,又避免了由此所造成的直接或间接的经济损失。
三、发明内容
本发明的目的在于解决阀门使用中的密封问题,耐久性问题,自动关闭问题。
本发明的阀体2中间沿外圆方向有一个四分之一周长的小槽,手柄1在其内滑动,止水板4和传压板5分别设有两个三角孔。本发明的特征在于,阀体2内设置一内套3,在其内壁上设有L型档槽阻止止水板4左右移动,一胶封7由两组对称安装在止水板4两侧。
本发明的有益效果是:密封效果好,耐久性好不易损坏,特殊功能是自动关闭。
四、附图说明
附图1是本发明的剖面透视图,手柄1;阀体2;内套3;止水板4;传压板5;环箍6;胶封7;环胶垫9;紧锢螺母10。
五、具体实施方式
阀体2中间沿外圆方向有一个四分之一周长小槽,使手柄1在其内滑动,上方为开起,下方为关闭。当手柄1在开起的位置,在水压力的作用下,经传压板5与止水板4之间所产生的摩擦力,处使止水板4及手柄1会停留在该位置上,阀门始终处在敞开状态。当管道停水时,阀门内压力作用,手柄1会自动带动止水板4下落到关闭的位置,即止水板4将传压板5的两个三角孔封闭,从而达到自动关闭水源之目的。
内套3;传压板5;环箍6;胶封7分别由一对对称安装止水板两侧。内套3内壁分别设有L型槽及凹槽,L型槽使止水板4只能转动不能移动,凹槽使传压板5(两个凸键)只能前后滑动不能转动。(凸、凹图1未画出)
