Abstract

本实用新型公开了一种右侧开式自闭止回阀,在阀体前面设有大法兰,在大法兰前面设有水封,在水封前面设有阀门,阀门与上、下铰链联为一体,在小法兰上设有12个等距离螺栓孔,本实用新型的关键技术是:将阀体大法兰端面右边的上、下铰链竖向布置,将小法兰上的12个等距离螺栓孔7以中心线为基准,全部向右位移一定角度(本实用新型位移5°)。这样,本实用新型安装后,可利用阀门的自重水平分力作动力,达到减小阀门的开启阻力和自动闭门的目的。

Description

右侧开式自闭止回阀
技术领域
本实用新型公开了一种右侧开式自闭止回阀。
背景技术
目前,世界各国的自来水泵房里普遍使用的是旋启式止回阀,这种止回阀存在开启角度小,水流阻力大,能源损耗多,使用寿命短等缺陷。到目前为止,在市场上还尚未见到一种开启角度大,水流阻力小,可以节约大量能源,使用寿命长的右侧开式自闭止回阀。
发明内容
本实用新型的目的是提供一种开启角度大,水流阻力小,可节约大量能源,使用寿命长的右侧开式自闭止回阀。
本实用新型的技术方案如下:一种右侧开式自闭止回阀,包括阀体、大法兰、水封、阀门、上、下铰链、小法兰和12个等距离螺栓孔等。其中,在阀体前面设有大法兰,在大法兰端面上设有水封,在水封前面设有阀门,阀门与上、下铰链联为一体,在小法兰上设有12个等距离螺栓孔。
本实用新型的关键技术是:将大法兰端面右边的上、下铰链竖向布置,将小法兰上的螺栓孔7以中心线为基准,全部向右位移一定角度(本实用新型位移5°)。这样,本实用新型安装后,可利用阀门的自重水平分力作动力,达到减小阀门的开启阻力和自动闭门的目的。
附图说明

图2是本实用新型结构主视图的剖面视图
具体实施方式
如图1、图2所示,一种右侧开式自闭止回阀,包括阀体1、大法兰2、水封3、阀门4、上、下铰链5、小法兰6和12个等距离螺栓孔7等。其中,在阀体1前面设有大法兰2,在大法兰2端面上设有水封3,在水封3前面设有阀门4,阀门4与上、下铰链5联为一体,在小法兰6上设有12个等距离螺栓孔7。
本实用新型的关键技术是:将大法兰2端面右边的上、下铰链5竖向布置,将小法兰6上的12个螺栓孔7以中心线为基准,全部向右位移一定角度(本实用新型为5°)。这样,本实用新型安装后,可利用阀门5的自重水平分力作动力,达到减小阀门5的开启阻力和自动闭门的目的。
