Patent ID: 7971854

Claim:
An Improved Replaceable Valve Shaft Sealing System that is adaptable to a valve stem that acts as the interface between an actuator and the valve orifice member, comprised of the elements; a valve shaft, having a proximal end containing a valve orifice interface and a distal end containing an actuator interface means and a sealing section that is terminated circumferentially at the upper end of said sealing section by an upper angularly inclined sealing gland ledge, and is terminated circumferentially at a lower end of said sealing section by a lower angularly inclined sealing gland ledge, said sealing section also designed to facilitate at least one sealing member and a lubrication reservoir, two angularly inclined sealing glands, each said gland is polygonal in shape containing at least one angled side that is congruent to each respective upper and lower said angularly inclined sealing gland ledges, said glands are in circumferential communication with said gland ledges, a compression inducing member designed to interface with said actuator interface means, said compression inducing member designed to create a compressive force onto said angularly inclined sealing gland, and a valve shaft housing having an interior bore and an external circumference, an upper end coinciding with said actuator interface means and a lower end coinciding with said valve orifice interface, said internal bore designed to allow for the incorporation of the said valve shaft thereinto through a chamfered opening, located near said upper end of said housing, and said distal end adapted to supply the means for attachment of said compression inducing member and said upper end of said housing providing a positive stop to the advancement of said compression inducing member.
