Abstract

本实用新型公开了一种橡胶瓣止回阀，包括阀体，所述阀体的左、右两端分别设有进水口端和出水口端，所述阀体中部的上侧壁上设有阀盖，所述阀体的底部安装有活塞，所述活塞的活塞杆一端伸入到阀体内，所述阀盖的内壁上铰接有橡胶瓣的一端，所述橡胶瓣的另一端铰接在活塞的活塞杆上。本实用新型结构简单，操作方便、准确。

Description

橡胶瓣止回阀
技术领域
本实用新型涉及一种橡胶瓣止回阀。
背景技术
止回阀的启闭件靠介质流动和力量自行开启或关闭，以防止介质倒流的阀门叫止回阀。止回阀属于自动阀类，主要用于介质单向流动的管道上，只允许介质向一个方向流动，以防止发生事故。橡胶瓣止回阀：阀体采用全通道结构，具有流量大、阻力小之优点。采用橡胶瓣止回阀，适用于高粘度、有悬浮物的工业及生活污水管网。
实用新型内容
    本实用新型提供一种通过活塞来控制阀门开启，达到精确控制的橡胶瓣止回阀。
本实用新型解决技术问题提供如下方案：
一种橡胶瓣止回阀，包括阀体，其特征在于：所述阀体的左、右两端分别设有进水口端和出水口端，所述阀体中部的上侧壁上设有阀盖，所述阀体的底部安装有活塞，所述活塞的活塞杆一端伸入到阀体内，所述阀盖的内壁上铰接有橡胶瓣的一端，所述橡胶瓣的另一端铰接在活塞的活塞杆上。
所述活塞杆与阀体之间设有密封钢套。
本实用新型在橡胶阀瓣的一端固定安装有活塞杆，通过调节活塞来控制止回阀的开关，这样相比原有的没有控制结构，更加容易精确的调节阀门的开关。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图，一种橡胶瓣止回阀，包括阀体1，所述阀体1的左、右两端分别设有进水口端2和出水口端3，所述阀体1中部的上侧壁上设有阀盖4，所述阀体1的底部安装有活塞5，所述活塞5的活塞杆6一端伸入到阀体1内，所述阀盖4的内壁上铰接有橡胶瓣7的一端，所述橡胶瓣7的另一端铰接在活塞5的活塞杆6上，所述活塞杆6与阀体1之间设有密封钢套8。
