Abstract
An improved valve disc assembly that can be easily and conveniently disassembled and reassembled with accurate positioning of the valve disc within the through bore of the valve body. A split clamp ring is provided for securing the seat retaining ring and valve seat onto the valve body for sealing engagement with the valve disc. The shaft through which movement of the valve disc to and between open and closed positions is accomplished, also includes a detent that automatically positions the valve disc within the bore upon reassembly of the valve.
Claims27
A method for assembling a valve assembly comprising the steps of:
- inserting a valve member within a bore of a valve body;
- inserting first and second shafts through first and second holes, respectively, in the valve body;
- releasably coupling the first and second shafts with the valve member;
- engaging a fixed detent on at least one of the shafts with the valve member thereby to center the valve member within the bore;
- mounting at least one shaft retainer to the valve body thereby to releasably secure the shafts to the valve body;
- and
- attaching an actuator to one of the shafts to permit selective rotation of the shaft for pivoting the valve member between closed and open positions in the valve body.

6 more elements
A valve assembly comprising:
- a valve body having a bore there through;
- a valve member removably and pivotally mounted within the valve body for selectively closing and opening the bore in the valve body;
- a first and a second valve arm each connected to and extending from the valve member;
- a first and a second shaft each projecting through the valve body and being mounted for rotation relative to the valve body, the first and second shafts being releasably coupled to the first and second valve arms, respectively;
- a fixed detent on at least one of the shafts engaging the respective valve arm for centering the valve member relative to the bore;
- and
- an actuator coupled to one of the shafts to selectively rotate the shafts relative to the valve body and to pivot the valve member within the valve body, for opening and closing the valve;
- whereby upon disassembly and re-assembly of the valve assembly the valve member is automatically centered relative to the bore by the engagement of the fixed detent on the shaft with the valve arm.
