Abstract:
The inventive concept discloses a completely integral ball valve manufactured by an injection molding process. The device comprises a valve core, a valve housing, a valve control handle, and inlet/outlet flow pipes, all forming an integral structure. The valve core is the primary component of the ball valve, and is comprised of a spherical enclosure, a valve ball, left and right leakage seal rings, a spherical enclosure cap, a valve stem affixed to the valve ball, and a valve handle. The valve core, valve housing, and left and right intake/outflow pipes are integrally assembled by injection molding. The injection molding process gives the ball valve higher flexion strength and greater durability as compared to the typical sweat soldering process. Precisely dimensioned mold sections ensure the accuracy of dimensions, fittings, and tolerances of the ball valve components during the injection molding. Primary materials used are polypropylene and high-density polyethylene

Claim (Index 6):
An improved method of manufacturing an integral plastic ball valve of the type having a spherical ball with a cylindrical through-hole, a left ball outlet, a right ball outlet, and a polygonal socket in the outer surface of said ball, the improvement comprising:\n (a) assembling a valve core consisting of a spherical enclosure, left and right leakage seal rings, a sealing gasket, the valve ball, a valve stem, and a spherical enclosure cap; (b) co-axially placing a left mold rod and a right mold rod into the left ball outlet and the right ball outlet, respectively; (c) providing an injection mold having a first mold cavity and a second mold cavity, each cavity comprising a concave profile corresponding to the shape of the valve core and mold rods, thereby forming a valve body housing encompassing said valve core; (d) placing the valve core and mold rods into the combined mold cavities in correspondence with a mold injection machine and initiating the pressurized flow of molten substance into the combined mold cavities; and (e) allowing an adequate cooling time for the mold, and afterwards, removing the integral valve body housing and the left and right outlet/inlet pipes.
