Abstract

本实用新型涉及一种对夹单瓣内装式止回阀,包括阀体、阀座和阀瓣,阀体采用对夹式与介质管道安装连接;主要是阀瓣采用销轴安装在阀体通道上方内壁,该销轴两端与阀体内壁的销孔动配合,在销轴与阀体之间安装弹性压圈。具有结构长度短、体积小、重量轻、使用方便、泄漏点少、密封可靠性好等优点。

Description

一种对夹单瓣内装式止回阀
技术领域
本实用新型属于阀门领域,特别是关于一种旋启式对夹止回阀。
背景技术
现有旋启式止回阀一般采用法兰连接,其结构主要有阀体、阀座、阀瓣、阀盖组成,其结构长度长、体积大、重量重、使用不方便,而且泄漏点较多。
发明内容
本实用新型的目的是针对现有技术的不足,提供一种结构长度短、体积小、重量轻、使用方便、泄漏点少、密封可靠性好的对夹单瓣内装式止回阀。
本实用新型的技术方案包括阀体、阀座和阀瓣,阀体采用对夹式与介质管道安装连接;主要是阀瓣采用销轴安装在阀体通道上方内壁,该销轴两端与阀体内壁的销孔动配合,在销轴与阀体之间安装弹性压圈。
本实用新型的优点是阀瓣采用销轴安装在阀体内壁,阀体采用对夹安装方式,其结构长度短、体积小、重量轻、使用方便、泄漏点少、密封可靠性好。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
如图1所示的对夹单瓣内装式止回阀,包括阀体1、阀座2和阀瓣3,阀体1采用对夹式与介质管道安装连接,阀座2安装在阀体1通道内,阀座2孔中心线与阀体1通道中心线重合;阀瓣3采用销轴6安装在阀体1通道上方内壁,该销轴6两端与阀体1内壁的销孔动配合,销轴6中间与阀瓣3上端固定连接,正向介质压力推动阀瓣3和销轴6在阀体1内壁的销孔内旋转开启,在销轴6与阀体1之间安装弹性压圈4,该弹性压圈4对阀瓣3产生关闭方向的力矩,反向介质压力和弹性压圈4的扭力共同作用,使阀瓣3与阀座2压紧密封配合。阀体1上端安装吊环5。
