Abstract:
A water valve assembly for controlling the flow of water through a water line, comprising:a) a housing;b) a main shutoff valve positioned within said housing for selectively controlling a flow of water through the water line; andc) a variable flow measuring assembly associated with said shutoff valve, and includingi) an axially movable sleeve contained within the housing and having an opening formed therein and movable from a closed position to an open position;ii) a sleeve insert mounted in the housing and disposed relative to the sleeve such that at least a portion thereof projects into the opening of the sleeve such that in the closed position there is a generally no flow condition through the shutoff valve;iii) wherein when the sleeve moves from the closed position towards the open position, water is permitted to flow around the sleeve insert and through the opening of the sleeve; andiv) a transducer for converting the movement of the sleeve to a measurement of water flow through the shutoff valve.
