DESCRIPTION OF THE PREFERRED EMBODIMENTS
The numeral 10 designates an elongate valve housing of the type which is adapted to be located in a relatively inaccessible area such as, by way of example, in a pit or underground sump area where it may be totally confined or contained, particularly in those instances in which it is -5a-B
used in conjunction with piping to control fluid media which contains radioactive materials The valve housing is provided with outer inlet and outlet ports and with inner inlet and outlet ports, wherein the outer inlet and outlet ports are defined by the outer, pipe-receptive ends 12 and 14 which are rigidly and permanently secured to pipes 16 and 18 by means of welding, whereby housing 10 is immovably located in the line through which the media to be controlled passes. In some instances the housing is located under water.
The inner inlet and outlet ports of the housing are designated by the numerals 20 and 22, respectively, each of which are provided in an elongate, internal, upwardly opening, centrally disposed bore 24 which may be cylindrical, or preferably tapered from a larger diameter adjacent its upper end to a smaller diametTic dimension at its lower end.
The lower end of bore 24 is completely closed, as at 25, whereby all access to the interior of housing 10, when associated in a line as in Fig. 1, is via the open upper end of said bore.
: A complete, fully operative, self-contained valving unit 30 ~see Fig. 2~ is adapted to be securely, though releasably, received within and operatively associated with bore 24 of the housing 10, with its inlet and outlet ports A and B in precise sealed alignment with the inner ports 20 and 22 of the housing 10.
Valving unit 30 includes a valve body 32 having an outer surface 34 which is the compliment of bore 24 of housing 10 to provide a slip fit wîth said bore and having an inner, elongate, valving-member-receptive bore, in which a valving-member 36 is rotatably journaled within a liner .
:' ' .. , . ' .
~1077913 of a non-metallic, inherently slippery, self-lubricating material such as polytetrafluoroethylene which forms continuous circular seals 40 adjacent opposite ends of the valving member, note Fig. 4, and which forms intermediate sealing areas 42, as illustrated in Fig. 6. Liner 38 is located between the valving member and corresponding portions of the valving-member-receptive bore of the valve body.
Valving member 36 includes a passageway 38 which is adapted ~-to be disposed in or out of alignment with ports A-B of the valve body 32, note Fig. 6.
As best illustrated in Fig. 5 the outer surface of the valve body 32 is provided with an upper circumferential groove 50 and a pair of laterally spaced lower circumferential grooves 5Z and 54, and with pairs of longitudinal grooves 56 and 58 which are disposed on opposite sides of ports A
