摘要： The present invention is a water conservation safety shut-off valve assembly for use on locations which normally have intermittent water usage but need to indicate when there is constant water usage, such as a leak. The valve assembly has a valve body with a fluid pathway and a valve plug held in an open position allowing water to flow through the pathway. As water flows through the pathway, a sensing device detects water flowing through the pathway and begins timing duration of water flowing through the pathway. If the water flow through the pathway stops, the timer value is reset to zero. If the water flows through the pathway, and the timer circuit reaches a predetermined manually set value, the valve closes the pathway, stopping the flow of water through the valve assembly. Preferably, the valve assembly indicates whether the valve is in an open or closed position. In addition, the valve assembly may generate its own electricity or may use standard battery or household power to operate the timer and related circuitry.

摘要： An automatic shut off valve comprising a housing having a main inlet, an outlet, a user inlet and a user outlet. A valve assembly is contained within the housing and is movable between an open and a closed position. In its open position, the user inlet and outlet are fluidly connected in series with the main inlet and main outlet while, conversely, in its closed position, the valve assembly sealingly closes and isolates both the user inlet and outlet from the main inlet and main outlet. A compression spring urges the valve assembly towards its closed position while a fluid flow rate greater than a predetermined amount into the user inlet retains the valve assembly in its open position. Consequently, in the event of an interruption or blockage of the fluid flow between the user inlet and outlet, the compression spring snaps the valve assembly to its closed position thus isolating the inlet and outlet from the main inlet and terminating fluid flow through the shut off valve. In the preferred form of the invention, a flow indicator provides an exteriorly visible indication of the flow rate through the shut off valve.
摘要翻译：一种自动关闭阀，包括具有主入口，出口，用户入口和用户出口的壳体。阀组件容纳在壳体内并且可在打开位置和关闭位置之间移动。在其打开位置，用户入口和出口与主入口和主出口串联地流体连接，而相反地处于其关闭位置，阀组件密封地关闭并隔离主入口和主体的用户入口和出口出口。压缩弹簧促使阀组件朝向其关闭位置，而大于预定量的流体流量进入用户入口将阀组件保持在其打开位置。因此，在用户入口和出口之间的流体流动的中断或阻塞的情况下，压缩弹簧将阀组件卡扣到其关闭位置，从而将进口和出口与主入口隔离并终止通过关闭的流体流阀。在本发明的优选形式中，流量指示器提供通过截止阀的流速的外部可见指示。

摘要： A valve assembly comprises a valve body having a bore therein, a first opening communicating with the bore, and a second opening displaced from the first opening and also communicating with the bore. A valve element is slidably mounted in the bore for longitudinal movement therein between first and second positions. In the first position the first opening is sealed from communication with the second opening, and in the second position communication between the first and second openings is permitted via the bore. The valve element includes a pressure reaction area exposed to fluid pressure from the second opening in the second position whereby the valve element is retained in the second position upon the presence of fluid pressure in the second opening in excess of a given limit. The assembly further comprises return means for automatically returning the valve element to the first position upon the absence of fluid pressure above the limit in the second opening.
