Abstract

1,190,307. Valves. KEROTEST MFG. CORP. 15 Oct., 1968, No. 48876/68. Heading F2V. A valve comprises a non-rising stem 6 with a threaded portion 15 co-operating with a reciprocating indicator 42, and a threaded portion 17 co-operating with a nut 21 of a locking swivel 24 rotatably connected thereto, which has a portion extending through an aperture in a bell-shaped cover 30, and a pin 35 passing through an aperture in the extending portion, to which a padlock 8 can be fitted to prevent the cover being removed. The indicator 42 has one, two, three or more arms 44 that project through slots 48 in the cover 30, and in Fig. 1, the slots are formed so that the cover can only be fitted when the indicator 44 is in its lowermost position and the valve is closed. Each arm 44 has an aperture 45, and is slidable on a pin 46 mounted on a gland 9. Stem 6 is formed in two parts, viz. a lower part, which is formed as a usual valve stem, and an upper part fitted thereto by pins 50. The stem can be formed as one piece. A padlock keeper can be passed directly through the aperture in the swivel 24. The pins 46 can bear on the side of the arms 44 to prevent rotation. The cover 30 can have a number of slots 48 of different lengths. An arm 44 could be bent downwardly to extend below an unslotted cover.
