摘要： In an expansion valve a valve body combines an inlet and outlet in an orifice in fluid communication therewith. A closure is positioned in the valve body and is movable between an opened and closed position to allow or prevent fluid to flow through the orifice from the inlet to the outlet. The valve body defines a bypass flow path which is in fluid communication with the outlet and inlet to allow fluid to flow from the outlet to the inlet, a bypass closure positioned in the bypass flow path is movable between an opened position and a closed position so that when said closures in said closed position fluid flowing from said outlet towards an inlet causes a bypass closure to move toward said opened position allowing fluid to flow on a reverse direction from the outlet to the inlet. When the closure moves toward the opened position fluid pressure maintains the bypass closure in the dosed position allowing fluid to flow from the inlet to the outlet. The bypass closure is free floating within the valve body.

摘要翻译： 在膨胀阀中，阀体将与其中流体连通的孔口中的入口和出口组合。 封闭件定位在阀体中并且可在打开和关闭位置之间移动，以允许或阻止流体从入口到出口流过孔。 阀体限定旁路流动路径，其与出口和入口流体连通，以允许流体从出口流到入口，位于旁路流动路径中的旁路闭合可在打开位置和关闭位置之间移动，因此 当在所述关闭位置处的所述闭合物从所述出口流向入口的流体导致旁路封闭件朝向所述打开位置移动时，允许流体在从出口到入口的相反方向上流动。 当封闭件朝向打开位置移动时，流体压力将旁路封闭件保持在计量位置，从而允许流体从入口流到出口。 旁路盖可自由浮动在阀体内。
