Abstract

一种阀门,一种智能水表用的“单向开关阀门”,表壳内单向阀片装在定阀片的反面,利用定阀片的反面与单向阀片密封,并可延阀轴滑动,可使智能水表不改变外部形状而实现开、关和防反向流的功能。

Description

单向开关阀门
技术领域
本实用新型涉及智能水表防止反向流的一种阀门,它是在同一个阀门上控制水流单向、开、关的功能。 
背景技术
目前,智能水表控制反向流主要采用机芯反转,带动齿轮反转,再带动指针反转来实现反向计数或另加装单向阀来实现的,反向计数误差大,另装单向阀则加大了表的体积。 
发明内容
为了防止反向流,本实用新型是在叠片阀门定阀片的反面增加一个单向阀片,以此来阻止水的反向流动。 
本实用新型解决其技术问题采取的技术方案是:1.在阀门内定阀片的反面,加一单向阀片、导向杆、定位杆和弹簧,弹簧的压力加到单向阀片上,使其与下阀片密封,有反向流时,水不能通过单向阀片与下阀片的密封面。在正向流时,水流会推开单向阀片正常流动。2. 单向阀片设有密封凸缘、导向孔和定位滑槽。 
本实用新型的有益效果是:利用叠片阀定阀片的反面增加单向阀,在不改变原智能水表外部形状的情况下实现开、关和防反向流功能。 
附图说明
下面结合附图和实施例对本实用新型进一步说明。 
附图1是阀门实施例的剖面图。 
附图2是单向阀片实施例的结构图。 
在附图1中,1.动阀片,2.定阀片,3.阀片密封圈,4.单向阀片,5.导向杆, 
6.弹簧,7.定位杆,8.壳体,9.阀体,10.阀体密封圈,11.阀压圈,12.阀轴,13.阀轴密封圈,14.轴端密封圈,15.硅胶密封圈,16.弹性压片。
在附图2中,1.密封凸缘,2.导向孔,3.定位滑槽
具体实施方式
在附图1中,导向轴(5)固定在壳体(8)和定阀片(2)的中心孔内,单向阀片(4)装在导向轴(5)上,阀片(4)可在导向轴(5)上滑动,水流正向流动时,水流顶开单向阀片(4),使水流出。弹簧(6)与壳体(8)和单向阀片(4)接触,使单向阀片(4)的密封凸缘与定阀片(2)的下平面紧密接触密封,因此防止了阀门的反向流。定位杆(7)装在壳体(8)上,防止单向阀片(4)旋转。 
在图2中,(1)是密封凸缘。(2)是导向孔,可在导向轴上滑动。(3)是定位滑槽,可在定位杆上滑动。 

Claims (1)

1.一种单向开关阀门, 在阀门内定阀片的反面,加一单向阀片、导向杆、定位杆和弹簧,弹簧的压力加到单向阀片上,使其与下阀片密封,有反向流时,水不能通过单向阀片与下阀片的密封面,在正向流时,水流会推开单向阀片正常流动。
