WATER SAFETY SHUT-OFF VALVE

Номер: US20160018017A1
Автор: Burlage Brian J., Burlage Roger A., Pesek Alex
Принадлежит:

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 starts a timer. The valve closes the pathway, stopping the flow of water through the valve assembly when the time elapses. The valve assembly indicates whether the valve plug is in an open or closed position.

A kinetically unyielding, statically compliant (KUSC) positive return valve action. In one embodiment, a guide is pivotally mounted and rotationally abuts a limiting bench. A pin mounted slidably on the guide is linked to a poppet valve, a driver positioning the pin along the guide. With the valve seated and the driver overtraveled a deflection opens up between the guide and the limiting bench that resolves the overtravel, which deflection is opposed by a forcing spring. As the valve is initially lifted, valve-lift kinetic force is buttressed against the guide mount and the limiting bench, neither of which yields. With increasing lift the pin position passes the guide mount axis to be cantilevered on the guide at maximal valve lift against valve-return kinetic force: this also is unyieldingly buttressed. The action is adjusted by positioning the limiting bench either manually or by hydraulic lash adjuster. 1. An action for cyclically translating a valve between a seated position and a lifted position , comprising:a driver that positions a guide and a pin with respect to one another, the guide being mounted for rotation about a first axis and the pin being rotatably mounted about a second axis and mounted to describe a predetermined path with respect to the guide, the second axis being substantially parallel to the first axis;an output member that is one of, the guide and the pin, linked to participate in positioning the valve;an abutment that may be operatively effected against a limiting bench which said abutment unyieldingly limits a rotation of the guide about the first axis, each position of the driver determining a position of the output member with the abutment in effect;a forcing member that opposes a deflection of the abutment, an instance of the deflection being produced by an overtravel of the driver at valve seating;a moment plane that includes the second axis and is normal to its momentary path with respect to the guide, the moment plane being removed ...
