Abstract

一种止回阀涉及一种建筑地漏中应用的止回流装置,本实用新型所述的止回阀主要由阀体、盖板和卡槽构成,阀体的入口与积水管连接,阀体的出口与排水管连接,其特征在于,在阀体的出口处有盖板,盖板通过卡槽与阀体连接。使用本实用新型所述的止回阀,可以排放积水,且又能有效阻止外面的水流入降层板,即有效地使降层板内保持干燥。

Description

一种止回阀
技术领域
本实用新型涉及一种建筑地漏中应用的止回流装置。
背景技术
目前的建筑地漏在同层排放中,如果地漏上方有比较大的水流下或地漏杂物堵塞造成排水不畅,地漏上方的水倒流有可能流向降层板返回到地面,这样容易造成地板长期处于潮湿当中,影响家居生活。
实用新型内容
本实用新型的目的只在于克服现有技术的缺陷,提供一种既可以排放积水,又能阻止外面的水流入的止回阀。
本实用新型所述的止回阀,主要由阀体、盖板和卡槽构成,阀体的入口与积水管连接,阀体的出口与排水管连接,在阀体的出口处有盖板,盖板通过卡槽与阀体连接。
所述的阀体出口处截面小于盖板截面。
所述的盖板打开的角度为0-90度。
使用本实用新型所述的止回阀,可以排放积水,且又能有效阻止外面的水流入降层板,即有效地使降层板内保持干燥。
附图说明
图1为本实用新型的结构示意图。
图中,1-阀体,2-盖板,3-卡槽。
具体实施方式
下面结合附图对本实用新型作进一步的说明,但不限于实施例。
实施例1
本实用新型所述的止回阀,主要由阀体1、盖板2和卡槽3构成,阀体1的入口与积水管连接,阀体1的出口与排水管连接,在阀体1的出口处有盖板2,盖板2通过卡槽3与阀体1连接,且阀体1的出口处截面不得大于盖板2截面。在同层排放中,有积水时推开盖板2一个角度排放积水,积水的水流越大推开盖板2的角度越大,没有积水时则盖板2因重力完全封住阀体的出口处,这样既能保证降层板积水排出且又能保证地漏内的水流不会流入降层板中,有效地使降层板内保持干燥。
