　　单向阀其实就是止回阀，也叫做逆止阀，所以这些叫法都表示同一种阀门。那单向阀型号其实就是止回阀的型号，若想知道具体的单向阀型号大全可参考《<a href="http://www.lumunon.com/famenjishu/checkvalve.html">常见止回阀型号大全</a>》。</p> <p> 　　单向阀作用主要是利用介质自身的流动而自动启闭阀瓣从而达到阻止介质逆向流动的自动阀门。</p> <p> 　　单向阀结构也分为升降式、旋启式、蝶式、隔膜式三种，通常称为<a href="http://www.lumunon.com/zhihuifa/h41h-h41y.html">升降式止回阀</a>、旋启式止回阀、蝶式止回阀以及隔膜式止回阀。</p> <p> 　　单向阀设计标准一般遵循GB13932、GB12221、GB12235、GB12236、JB/T3595、JB/T8937、API594、API 6D、ANSI B16.34、E101等标准。</p> <p> 　　单向阀原理<br /> 　　<img alt="单向阀原理"
