止回阀是指依靠介质本身流动而自动开、闭阀瓣,用来防止介质倒流的阀门,又称逆止阀、单向阀、逆流阀、和背压阀。止回阀属于一种自动阀门,其主要作用是防止介质倒流、防止泵及驱动电动机反转,以及容器介质的泄放。

 

工作原理

止回阀还可用于给其中的压力可能升至超过系统压的辅助系统提供补给的管路上。止回阀主要可分为旋启式止回阀(依重心旋转)与升降式止回阀(沿轴线移动)。

止回阀这种类型的阀门的作用是只允许介质向一个方向流动,而且阻止反方向流动。通常这种阀门是自动工作的,在一个方向流动的流体压力作用下,阀瓣打开;流体反方向流动时,由流体压力和阀瓣的自重合阀瓣作用于阀座,从而切断流动。

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,并使阀瓣真实的、一体的与阀座接触。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。旋启式止回阀在完全打开的状况下,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。

液压机,以高压液体(油、乳化液等)传送工作压力的锻压机械。液压机的行程是可变的,能够在任意位置发出大的工作力。液压机工作平稳,没有震动,容易达到较大的锻造高层度,适合于大锻件的锻造和大规格板料的拉深、打包和压块等工作。液压机主要包括水压机和油压机。某些弯曲、矫正、剪切机械也属于液压机一类。

液压机工作原理

利用帕斯卡定律制成的利用液体压强传动的机械,种类很多。当然,用途也根据需要是多种多样的。如按传递压强的液体种类来分,有油压机和水压机两大类。水压机产生的总压力较大,常用于锻造和冲压。锻造水压机又分为模锻水压机和自由锻水压机两种。模锻水压机要用模具,而自由锻水压机不用模具。

 

旋转锻压机,锻造与轧制相结合的锻压机械。旋转锻压机的基本传动方式与轧机相似。在旋转锻压机上,变形过程是由局部变形逐渐扩展而完成的,所以变形抗力小,机器质量小,工作平稳、无震动,易实现自动化生产。辊锻机、成形轧制机、卷板机、多辊矫直机、辗扩机、旋压机等都属于旋转锻压机。

自动送料装置,在锻压机械中有的自动送料装置,此处指用於开式压力机、闭式压力机、多工位压力机、高速压力机等单机或冲压自动线进行板料加工的自动送料装置。
