Abstract: A system includes a choke valve having a fluid inlet configured to receive a fluid at a first pressure and a fluid outlet configured to output the fluid at a second pressure. The choke valve also includes a fixed component and a movable component defining a throttling orifice between the fluid inlet and the fluid outlet. Additionally, the movable component is configured to automatically move relative to the fixed component in response to a change in the first pressure to maintain a consistent percent pressure drop between the first pressure at the fluid inlet and the second pressure at the fluid outlet.

Abstract translation: 一种系统包括具有流体入口的阻塞阀，所述流体入口构造成在第一压力下接收流体，并且流体出口配置成在第二压力下输出流体。 阻塞阀还包括固定部件和在流体入口和流体出口之间限定节流孔口的可移动部件。 另外，可移动部件构造成响应于第一压力的变化而相对于固定部件自动移动，以保持流体入口处的第一压力和流体出口处的第二压力之间的一致的百分比压降。
