摘要： A flow shut off or throttling valve is provided in a sprinkler nozzle housing to enable a nozzle to be changed without having to turn off a flow pressure source. The valve intersects a flow path through the nozzle housing and has an opening such that when the opening is aligned with the flow path, a flow stream can flow unobstructed through the flow path. The valve is movable between a fully open position in which the opening is aligned with the flow path and a closed position which blocks the flow stream from flowing to a nozzle disposed at an outlet passage of the flow path. The valve may be constructed to be either slidable or rotatable between the two positions, and is actuated by a gearing arrangement which is operable at the exterior of the nozzle housing. The external valve actuator may function as a physical barrier to retain the removable nozzle in the nozzle housing when the valve is open and to disengage the nozzle when the valve is closed.
摘要翻译： 在喷洒喷嘴壳体中设置有流动切断阀或节流阀，以使得能够改变喷嘴而不必关闭流量压力源。 阀与通过喷嘴壳体的流路相交，并且具有开口，使得当开口与流动路径对准时，流动流可以畅通无阻地流过流动路径。 所述阀可在其中所述开口与所述流动路径对准的完全打开位置和封闭位置之间移动，所述关闭位置阻止所述流动流流向设置在所述流动路径的出口通道处的喷嘴。 阀可以构造成在两个位置之间可滑动或可旋转，并且由可在喷嘴壳体的外部操作的传动装置致动。 当阀门打开时，外部阀门致动器可用作物理屏障，以将可移除喷嘴保持在喷嘴壳体中，并且当阀门关闭时使外部阀门致动器脱离喷嘴。

摘要： A diaphragm operated valve having the diaphragm attached at its lower end to a valve closure plug, and movable therewith, and attached at its upper end to a portion of valve body that forms the pressure cavity. The diaphragm has a stepped portion between its upper and lower ends which folds back on itself when the valve opens. The valve body has shoulder portions that support the diaphragm when the valve is closed to avoid stressing the diaphragm material due to pressure in the pressure chamber. This allows the outside diameter of the diaphragm to be minimized, and eliminates the need for fabric reinforcement. A filter screen is positioned flush with the surface of the valve plug so that high velocity flow across the screen while the valve is opening and closing removes accumulated dirt thereby making the screen self cleaning.
摘要翻译： 隔膜操作阀，其隔膜在其下端附接到阀闭塞塞并可与其一起移动，并在其上端附接到形成压力腔的阀体的一部分。 隔膜在其上端和下端之间具有阶梯部分，当阀门打开时，其自身折回。 当阀门关闭时，阀体具有支撑隔膜的肩部，以避免由于压力室中的压力而对隔膜材料施加压力。 这样可以使膜片的外径最小化，并且不需要织物加固。 过滤网与阀塞的表面平齐地定位，使得当阀门打开和关闭时，跨过筛网的高速流动除去积聚的污垢，从而使筛网自清洁。
