Abstract
A self-contained, operative, valving unit which includes a valve body having inlet and outlet ports, and a rotatable valve plug is securely though removably housed within a valve housing having inlet and outlet ports which are permanently secured to pipes through which the fluid media to be controlled is conveyed to and from the housing, and wherein the entire valving unit, per se, is received within a valving-unit-receptive bore of the valve housing with its inlet and outlet ports in cooperative, aligned, fluid tight relationship with respect to corresponding inlet and outlet ports interiorly of the valve housing whereby the flow of fluid media through the valve housing is controlled by the removable valving unit.
Claims14
A valve assemblage comprising a valve-receptive outer housing and a removable self-contained valve unit which is received in said housing for controlling the flow of fluid through said housing wherein:
- said housing includes a centrally disposed upwardly opening bore the lower end of which is closed so that access to said bore occurs only via the open top thereof, axially aligned outer inlet and outlet ports spaced outwardly from and on opposite sides of said bore, said ports defining means for connecting said housing in a pipe line, and axially aligned inner inlet and outlet ports in open communication with said bore and in laterally spaced relationship with said corresponding outer inlet and outlet ports and in communication therewith;
- said valve unit is removably mounted in said bore of said housing, said valve unit includes a valve body and a rotatable valving member unconnected to each other, said valve body has an upwardly opening bore therein for the reception of said rotatable valving member, said valve body provides subjacent support for said rotatable valving member to prevent downward movement of said rotatable valving member with respect to said valve body, said valve body includes axially aligned inlet and outlet ports communicating with said bore in said valve body, said valving member has a passage extending therethrough for movement into and out of alignment with said inlet and outlet ports in said valve body, said valving member blocking said inlet and outlet ports in said valve body when said passage in said valving member is out of alignment with said inlet and outlet ports in said valve body, and sealing means is disposed between said valve body and said valving member to prevent contact between said valve body and said valving member while preventing fluid leakage therebetween;
- means to releasably connect said valve body to said housing;
- means attached to said valve body and accessible from a location above and remote from said housing for withdrawing or lowering said valve unit from or into said bore in said housing, said attached means extending upwardly from said valve body and being accessible irrespective of whether said valve body is releasably connected to said housing by said releasable connecting means;
- rotation means, separate from and independent of said attached means, accessible from a location above and remote from said housing to enable rotation of said valving member within said valve body;
- and each of said attached means and said rotation means being accessible from a location above and remote from said housing without the other of said attached means and said rotation means being moved.

A valve assemblage comprising a valve-receptive outer housing and a removable self-contained valve unit which is received in said housing for controlling the flow of fluid through said housing wherein:
- said housing includes a centrally disposed upwardly opening bore, outer inlet and outlet ports, and inner inlet and outlet ports in open communication with said bore and in laterally spaced relationship with said corresponding outer inlet and outlet ports and in communication therewith;
- a first pipe is fixed to said housing and communicating with said outer inlet port in said housing, a second pipe is fixed to said housing and communicating with said outer outlet port in said housing, said valve unit is removably mounted in said bore of said housing, and said bore of said housing is formed to provide closed communication of said pipes with each other when said valve unit is removed from said bore of said housing except for the upward opening in said bore of said housing through which said valve unit is removed so that leakage of fluid is prevented;
- said valve unit includes a valve body and a rotatable valving member unconnected to each other, said valve body has an upwardly opening bore therein for the reception of said rotatable valving member, said valve body provides subjacent support for said rotatable valving member to prevent downward movement of said rotatable valving member with respect to said valve body, said valve body includes inlet and outlet ports communicating with said bore in said valve body, said valving member has a passage extending therethrough for movement into and out of communication with said inlet and outlet ports in said valve body, said valving member blocking said inlet and outlet ports in said valve body when said passage in said valving member is not in communication with said inlet and outlet ports in said valve body, and sealing means is disposed between said valve body and said valving member to prevent contact between said valve body and said valving member while preventing fluid leakage therebetween;
- means to releasably connect said valve body to said housing;
- means attached to said valve body and accessible from a location above and remote from said housing for withdrawing or lowering said valve unit from or into said bore in said housing, said attached means extending upwardly from said valve body and being accessible irrespective of whether said valve body is releasably connected to said housing by said releasable connecting means;
- rotation means, separate from and independent of said attached means, accessible from a location above and remote from said housing to enable rotation of said valving member within said valve body;
- and each of said attached means and said rotation means being accessible from a location above and remote from said housing without the other of said attached means and said rotation means being moved.
