流体调节器、流体阀体、用于流体调节器的阀体
摘要：
本公开涉及流体调节器、流体阀体以及用于流体调节器的阀体。示例性的流体调节器包括一具有主通道的主体，该主通道限制限定流体地耦接入口和出口的出孔腔以连接入口和出口，其中该主通道限定在入口和孔腔之间限制出的入口体积容积边界，以及在孔腔和出口之间限制出的出口容积边界。该出口容积边界的一部分包括一邻近孔腔的内壁。一阀塞设置于该通道的第二部分内，从而该内壁大体上实质上围绕阀塞的外表面以大体上实质上限制流体在该内壁和阀塞的外表面之间朝向喉部流动。阀体具有位于出口容积边界内的第二流体通道以在流体流过孔腔时增加朝向阀体的喉部的流体流动。
摘要（英）：

The utility model relates to a fluid regulator, a fluid valve body and a valve body used for the fluid regulator. The fluid regulator in an example comprises a main body with a main passageway, wherein the main passageway defines an orifice to fluidly couple an inlet and an outlet so as to connect the inlet and the outlet, and the main passageway defines an inlet volume boundary between the inlet and the orifice and an outlet volume boundary between the orifice and the outlet. A portion of the outlet volume boundary includes an inner wall adjacent the orifice. A valve plug is disposed within a second portion of the passageway such that the inner wall substantially surrounds an outer surface of the valve plug to substantially restrict fluid flow between the inner wall and the outer surface of the valve plug and toward a throat. The valve body has a secondary fluid passage within the outlet volume boundary to increase fluid flow toward the throat of the valve body when a fluid flows across the orifice.
