Abstract: 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.
Abstract translation: 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。

Abstract: 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.

Abstract: A turbine assembly for a rotary sprinkler head includes a flow control valve, a turbine housing having a fluid inlet and fluid outlet ports, and a rotor mounted in the housing. The flow control valve is moveable between a closed position and a maximum open position, and is spring biased towards the closed position in which all of the fluid flowing into the sprinkler head initially flows into the turbine assembly. When the flow rate through the sprinkler head is sufficient to open the valve, a portion of the fluid flow passes through the valve to bypass the turbine assembly. As the flow rate continues to increase, the valve opens further until it reaches the maximum open position. Once the valve is opened to a predetermined point, as it opens further, up to the maximum position, the valve also increasingly throttles the fluid outlet ports up to a point short of complete blockage of the outlet ports.
Abstract translation: 用于旋转式喷洒头的涡轮组件包括流量控制阀，具有流体入口和流体出口的涡轮壳体，以及安装在壳体中的转子。 流量控制阀可在关闭位置和最大打开位置之间移动，并且被弹簧偏压到关闭位置，在关闭位置，流入喷洒头的所有流体最初都流入涡轮机组件。 当通过喷洒头的流量足以打开阀时，一部分流体流动通过阀以绕过涡轮组件。 随着流量的不断增加，阀门进一步打开直到达到最大打开位置。 一旦阀门打开到预定点，当其进一步打开时，直到最大位置，阀门也越来越多地将流体出口端口节流到直到出口端口完全堵塞的程度。

Abstract: A selected range arc settable spray nozzle with pre-set table precipitation rate in which the arc of coverage adjustment is coupled to an upstream flow throttling valve. As the arc of coverage is adjusted, the opening of the upstream flow throttling valve is proportionally adjusted to maintain the precipitation rate substantially constant independent of arc of coverage adjustments. Upstream flow throttling achieved by use of pre-selected number of larger slots for desired flow whose opening area is varied as the arc is being set. The precipitation rate is set by adjusting the throttling valve to provide the desired flow rate for the maximum arc of coverage setting. A pressure compensating valve may also be provided.

Abstract: A check valve for a sprinkler in accordance with an embodiment of the present application includes a valve body adapted to be positioned at an inlet of the sprinkler, wherein the valve body includes a central opening through which water flows into the sprinkler, a rib extending downwardly from the valve body at a location beyond the margin of the central opening, a valve member configured to cooperate with the central opening to open and close the valve. The valve member includes a valve stem extending downwardly from the valve member, and positioned and configured to be movably supported in a guide ring formed at a lower end of the rib, wherein the valve stem is movable vertically to move the valve member to its open and closed positions. The check valve further include a resilient member biasing the valve stem such that the valve member remains in the closed position until water pressure pushing against the valve member overcomes the bias of the resilient member.
