Description

对夹式碟式止回阀
技术领域
    本实用新型涉及到阀门领域，具体的是一种对夹式碟式止回阀。
背景技术
    止回阀又称单向阀或逆止阀，其作用是防止管路中的介质倒流，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。
止回阀的阀瓣在流体压力作用下开启，流体从进口侧流向出口侧。当进口侧压力低于出口侧时，阀瓣在流体压差、本身重力等因素作用下自动关闭以防止流体倒流。 
发明内容
    本实用新型提供了一种简单而方便实用的对夹式碟式止回阀。
本实用新型的技术方案： 
对夹式碟式止回阀，包括环形阀体，其特征在于：所述的环形阀体直径方向上固定并密封安装有转轴和导柱，所述的转轴上转动安装有对夹式阀板，所述的导柱上套装并固定有扭簧，所述的扭簧两端的触角弹性接触在所述的对夹式阀板上，所述的环形阀体为带有台阶的环形阀体；所述的对夹式阀板的直径大于所述的环形阀体内的小径并小于其大径，所述的台阶上连接有密封圈。
所述的对夹式碟式止回阀，其特征在于：所述的扭簧处于松弛状态时，所述的对夹式阀板为V字形，所述的对夹式阀板整体为圆形。 
本实用新型的优点： 
本实用新型结构简单，制造安装流程简单，防止回流作用好，安全性高。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
    对夹式碟式止回阀，包括环形阀体1，环形阀体1直径方向上固定并密封安装有转轴2和导柱3，所述的转轴2上转动安装有对夹式阀板4，所述的导柱3上套装并固定有扭簧5，所述的扭簧5两端的触角弹性接触在所述的对夹式阀板4上，所述的环形阀体1为带有台阶的环形阀体；所述的对夹式阀板4的直径大于所述的环形阀体1内的小径并小于其大径，所述的台阶上连接有密封圈6，扭簧5处于松弛状态时，所述的对夹式阀板4为V字形，所述的对夹式阀板4整体为圆形。
