Abstract
947,858. Valves. BELL'S ASBESTOS & ENGINEERING Ltd. June 24, 1960 [Aug. 4, 1959], No. 26551/59. Heading F2V. A screw-down lift valve, Fig. 1, has a valve member or clack 13 which is removably carried on the valve spindle 3 and a valve seat 15 which is removable from the valve body 1, and a set of replacement clacks and seats adapted to fit the same spindle and body is provided, these replacements constituting otherwise a number of alternative constructions (Figs. 3 to 7). In Fig. 3, the clack and seat are of stainless steel having deposited thereon inserts 16, 17 of " Stellite " (Registered Trade Mark) forming wear resisting faces. In Fig. 4, a shroud 18 of the clack seats on an outer conical surface of the seat whilst a plug part of the clack engages in the seat orifice, an annular space 25 being formed between the shroud and plug part to prevent " wire-drawing " on opening the valve. Fig. 5 is similar to Fig. 4 excepting that the plug part of the clack has a conical end to provide a graduated opening. In Fig. 6 a flat faced clack has an inverted sealing ring 19 of rectangular section engaging a flat surface of the seat. In Fig. 7, the sealing ring of Fig. 6 is replaced by an 0-ring seal 22. A screwed part 9 of the spindle may be positioned inwardly of gland packing 7, or outwardly of this packing. Specification 884,529 is referred to.
