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 1):
An integral plastic ball valve, said ball valve comprising:\n (a) a spherical enclosure having a generally cylindrical structure and further having a collar with a circular through-aperture, a circular inner face, a peripheral surface, and a barrel opening, said barrel opening having an annular-shaped outer face, said outer face being oriented parallel to the axis of the circular aperture; (b) identical left and a right leakage seal rings, each seal ring having a continuous circumferential lip on one side of the ring; (c) a rod-shaped valve stem having a notch on the first end of said stem, a plurality of installed gasket O-rings, and a polygonal cross-section on the second end of said valve stem; (d) a valve handle having a cavity corresponding to the notch of said valve stem; (e) a valve ball comprising i) a sphere; ii) a through-hole corresponding to an axis of the valve ball, said through-hole thereby forming a left ball outlet and a right ball outlet, and iii) a topmost polygonal socket with a cross-section corresponding to the second end of said valve stem; (f) an annular-shaped spherical enclosure cap comprising a cap opening corresponding to the right ball outlet; a circumferential flange constructed about the cap opening; an annular-shaped cap first face on the first side of the spherical enclosure cap, and exterior to said flange; a cap second face oriented about the inner perimeter of said flange and having an inner diameter corresponding to the right ball outlet; and said cap first face having an inner and outer diameter corresponding to the outer face of said barrel opening (g) a sealing gasket having an outer diameter corresponding to the inner diameter of said circumferential flange; (h) a left flow pipe integral to and coaxial with the left ball outlet and a right flow pipe integral to and coaxial with the right ball outlet; and (i) a valve body housing.
