Claims
- 1. A reinforced plastic valve comprising,
- a valve body molded of plastic material and having a means for reinforcing said valve body,
- said valve body having a cylindrical bore with an upper portion and a lower portion, said upper portion and said lower portion both having a cylindrical edge,
- said lower portion of said cylindrical bore having a fluid inlet opening and fluid outlet opening,
- a valve plug and actuator assembly having a plug portion positioned in the lower portion of said chamber between said inlet opening and said outlet opening,
- said plug and actuator assembly having means thereon to control the flow of fluids through said chamber,
- said plug and actuator assembly being molded from plastic materials to form a unitary body including a plug portion and an actuator portion, said plug portion molded from a plastic material having high dimensional stability, and said actuator portion molded from a plastic material having high impact resistance,
- said plug portion having a flow passage therethrough,
- said plug portion being rotatable in said chamber between an opened position with said flow passage aligned with said inlet opening and said outlet opening and a closed position where said flow passage is not aligned with said inlet opening and said outlet opening to control the flow of fluid through said chamber lower portion,
- said actuator portion extending upwardly from said plug portion through said chamber upper portion, said actuator portion having a circular flange and an upwardly extending stem,
- said circular flange positioned in overlying relation with said valve body upper portion cylindrical edge and thereby closing said valve body chamber upper portion,
- said plastic valve body having a plastic disk-like closure member closing said valve body cylindrical bore lower portion, said plastic closure member being fused to said valve body cylindrical bore lower portion cylindrical edge so that when said fluid pressure within said valve body exceeds a preselected pressure a portion of said plastic closure member disengages from said valve body to release the fluid pressure from said chamber.
- 2. A reinforced plastic valve as set forth in claim 1 in which,
- said disk-like closure member having a cup-shaped configuration with an upstanding angular shoulder and a circular flange extending therefrom,
- said circular flange having a surface fused to said valve body lower portion cylindrical edge.
- 3. The reinforced plastic valve as set forth in claim 1 in which,
- said actuator portion of said plug and actuator assembly having circumferential projections extending into said plug portion of said plug and actuator assembly.
- 4. Said reinforced plastic valve as set forth in claim 3 in which,
- said circumferential projections on said actuator portion of said valve member having apertures to permit plastic injected into a mold to form said plug to flow through said apertures and form a unitary plug-actuator assembly.
