ABSTRACT:
A live-load device for applying a compressive force to packing or gasket material in a valve or pipe conduit junction. The device incorporates spring-washers having resilient blades for imparting a spring force. The spring force is transmitted from each blade through a ball-bearing seated at a selected one of a plurality of contact points along the blade tip. The spring constant of the device is selected by positioning the ball-bearing at a particular one of the contact points. This adjustment capability makes the spring device universally adaptable to a wide variety of valves and conduit junctions.
