止回阀是指启闭件为圆形阀瓣并靠自身重量及介质压力产生动作来阻断介质倒流的一种阀门。属自动阀类,又称逆止阀、单向阀、回流阀或隔离阀。阀瓣运动方式分为升降式和旋启式。升降式止回阀与截止阀结构类似,仅缺少带动阀瓣的阀杆。介质从进口端(旋启式止回阀有一个斜置并能绕轴旋转的阀瓣,工作原理与升降式止回阀相似。止回阀常用作抽水装置的底阀,可以阻止水的回流。止回阀与截止阀组合使用,可起到安全隔离的作用。缺点是阻力大,关闭时密封性差
工作原理
其中止回阀就属于这种类型的阀门,它包括旋启式止回阀和升降式止回阀。旋启式止回阀有一介铰链机构,还有一个像门一样的阀瓣自由地靠在倾斜的阀座表面上。为了确保阀瓣每次都能到达阀座面的合适位置,阀瓣设计在铰链机构,以便阀瓣具有足够有旋启空间,并使阀瓣真正的、全面的与阀座接触。阀瓣可以全部用金属制成,也可以在金属上镶嵌皮革、橡胶、或者采用合成覆盖面,这取决于使用性能的要求。旋启式止回阀在打开的状况下,流体压力几乎不受阻碍,因此通过阀门的压力降相对较小。升降式止回阀的阀瓣坐落位于阀体上阀座密封面上。此阀门除了阀瓣可以自由地升降之外,其余部分如同截止阀一样,流体压力使阀瓣从阀座密封面上抬起,介质回流导致阀瓣回落到阀座上,并切断流动。根据使用条件,阀瓣可以是全金属结构,也可以是在阀瓣架上镶嵌橡胶垫或橡胶环的形式。像截止阀一样,流体通过升降式止回阀的通道也是狭窄的,因此通过升降式止回阀的压力降比旋启式止回阀大些,而且旋启式止回阀的流量受到的限制很少
