flow reverse-direction

When the control valve when the reverse, so that both fluid along the direction of movement of spool when closed, the flow control valve capacity will be increased.

当调节阀反向使用时，既流体沿着使阀芯关闭的方向流动时，调节阀的流通能力会增大。

The surface material under the condition of half melting is compelled to flow to the reverse direction, that is none restraint free surface. Thus, the grinding triturate is formed.

由于该区内材料产生了巨大的单向反弹力，迫使已处于半熔化状态的表面材料向压力相反方向即无约束的自由表面流动，从而使磨屑形成。
