ABSTRACT:
A quick-disconnect system for selectively connecting a slurry tank to a fluid supply line includes a first valve on the slurry tank and a second valve in the supply line fitting. Each of such valves includes a piston having a tapered neck extending from such valves. Each such piston slides within a cylinder having fluid passages extending through the walls of such cylinder, and each cylinder is received within a valve body. A biasing spring ordinarily advances such pistons to cause enlarged side wall portions of such pistons to seal the fluid passages that extend through the cylinders. Each piston has a tapered neck portion that extends outwardly from the valve, and upon connection of quick-disconnect system, the tapered neck portions of the pistons engage each other to simultaneously overcome the biasing springs. As each piston retracts, the enlarged side wall portions of the pistons slide past the fluid passages that extend through the cylinders, and are removed from the abrasive fluid flow path. The biasing springs are contained between the pistons and the closed ends of the cylinders, thereby isolating the biasing springs from the abrasive fluid flow path.
