Abstract
946,354. Valves. AUDCO Ltd. Aug. 2, 1962 [Aug. 8, 1961], No. 28547/61. Heading F2V. A plug valve comprises a tapered plug comprising a core member, formed with a through passage, and a sleeve of anti-friction synthetic material, such as p.t.f.e. on the core, the interengaging surfaces of the core and sleeve being of non-circular cross-section over at least a portion of their length. In the form shown in Fig. 5, the core 10 is of substantially octagonal cross-section and is provided with lips 14 surrounding the flow passage 12, the sleeve 11 being mounted round the core. In a modification, the lips 14 are omitted. Peripheral circumferential grooves may also be provided on the core on either side of the passage 12. In a further modification, lips 15, Fig. 7, are provided around the flow passage and the core is formed with longitudinal grooves which receive the sleeve 11. The peripheral grooves may be provided as above and the core may be of octagonal shape above and below the passageway 12. In a further modification the core is provided with four raised portions so that in the regin of the passageway the sleeve does not extend all round the core.
