Abstract

本实用新型公开了一种止回阀,它包括阀体(4)和位于阀体(4)内的阀瓣(6),阀体(4)的顶部设有阀盖(3),所述的阀瓣(6)铰接在阀盖(3)上。本实用新型使流体通过止回阀更好流畅,提高了止回阀的生产效率。

Description

一种止回阀
技术领域
本实用新型涉及止回阀,尤其是止回阀的阀瓣连接装置。
背景技术
止回阀是一种常用的阀门,主要用于防止管道内的流体倒流,造成设备的损坏。止回阀包括阀体和位于阀体内的阀瓣,目前,阀瓣都是这样连接的,阀体内设有凸台,阀瓣铰接在凸台上。上述结构的缺点是由于阀体设有凸台,流体通过时,对流体形成了阻力,使流体流通不畅。同时,由于阀体内设置凸台,给阀体铸造带来了较大的困难,降低了生产效率。
实用新型内容
本实用新型的目的就是解决止回阀因阀瓣铰接在阀体内造成流体流通不畅,降低了制造效率的问题。
本实用新型采用的技术方案是:一种止回阀,它包括阀体和位于阀体内的阀瓣,阀体的顶部设有阀盖,其特征是所述的阀瓣铰接在阀盖上。
采用上述技术方案,由于阀瓣铰接在阀盖上,这样阀体内不需要设置凸台,方便了流体在阀体内的通过,同时给阀体的铸造带来了方便,提高生产效率。
本实用新型有益效果是:使流体通过止回阀更好流畅,提高了止回阀的生产效率。
附图说明
图1为本用新型示意图。
图2为图1的左视图。
具体实施方式
    本实用新型一种止回阀,如图1、图2所示,它包括阀体4和位于阀体4内的阀瓣6,阀体4的顶部设有阀盖3,阀瓣6铰接在阀盖3上。本实施例是这样实现的,阀盖3的底面一侧固连有两个平行向下伸出的凸台2,阀瓣6的背面连接有摇臂5,摇臂5呈倒L形,一端通过螺栓1活动连接在凸台2上。
