摘要： A cylindrical valve body for a sleeve valve including the valve body to be secured to the upper wall of a reducing chamber and a valve cylinder gate having open upper and lower ends and slidably fitted in the valve body, the gate communicating at its upper end with an inlet elbow for pressurized water. The valve body is formed in its peripheral wall with a multiplicity of straight bores each having a cylindrical nozzle member fixedly fitted therein and provided with an outwardly tapered port. This construction renders the tapered ports easy to form in the wall of the valve body. The tapered port is closable with a plug including a conical head in conformity with the tapered port and a threaded pin projecting from the top end of the head by inserting the plug into the port and screwing a nut on the threaded pin. By altering the number of the tapered ports so closed, the distribution of open ports is variable to improve the flow ratio characteristics of the valve body.
摘要翻译：一种用于套筒阀的圆柱形阀体，其包括要固定在还原室上壁上的阀体和具有敞开的上端和下端并具有可滑动地装配在阀体中的阀门门，该门在其上端与用于加压水的入口弯头。阀体在其周壁上形成有多个直孔，每个直孔具有固定地装配在其中并具有向外锥形端口的圆柱形喷嘴构件。这种结构使锥形端口易于在阀体的壁上形成。锥形端口可以使用包括锥形头的插头来封闭，锥形头与锥形端口一致，以及通过将插头插入端口并将螺母拧到螺纹销上从而从头部的顶端突出的螺纹销。通过改变如此关闭的锥形端口的数量，开口的分布是可变的，以改善阀体的流量比特性。
