ABSTRACT:
A liquid storage tank overfill prevention assembly that includes an outer housing, an insert that includes fill flow ports, a shut-off sleeve to slowly close off the flow ports and a float member for controlling the sleeve in response to the rise of the stored liquid level. As the product flows through the assembly it is diverted through flow ports in the insert to the inside of the outer body and through the fill pipe installed in the bottom of the valve. As the product level in the tank increases, the float rises and the shut-off sleeve relatively slowly covers or closes the flow ports in the insert. The shut-off is gradual and no hydraulic shock is felt through the valve. For further benefit, the shape of the shut-off sleeve diverts the liquid flow steam through the ports and is shaped to maintain substantial laminar liquid flow until the liquid exits the ports into the housing interior. Thus, resistance or decrease in the liquid flow rate is minimized notwithstanding this diversion and maximum flow rates can be achieved when the ports are fully open for the rapid filling of the tank.
