Автор: Guthrie Kevin J.
Принадлежит: LAVELLE INDUSTRIES, INC.

An improved fill valve has a pivot valve body that is pivotally suspended immediately below a float housing and is movable between two positions. In a first position, the pivot valve body blocks the flow of water from the float housing. In a second position, the pivot body allows the flow of water from the float housing. The pivot valve body has two top compartments, each separated from the other by a wall. The first compartment retains an amount of water in it. The second compartment functions as a water flow restriction apparatus and includes an upwardly-extending member for sealing off a check valve that is disposed within the bottom of the float housing. A pressure compensating drip emitter allows water to trickle into the float housing at a very slow rate. The emitter comprises a labyrinth structure having a plurality of serpentine pathways formed in its outer surface. 1.

The double action float valve utilizes a valve body, a heavy filling obturator positioned within the valve body, a light inverse obturator positioned within the heavy filling obturator, and a float connected to the heavy filling obturator. When the inflow pressure from the pipe is greater than the outflow pressure of the tank, the tank is filled until the float reaches a predetermined level. When the outflow pressure of the tank is greater than the inflow pressure, the double action float valve is automatically reconfigured to discharge the fluid from the tank into the pipe.
