Abstract

1,256,727. Valves. K. FUJIWARA. 1 July, 1969 [7 Aug., 1968; 23 Aug., 1968; 30 Aug., 1968; 18 Nov., 1968], No. 33218/69. Heading F2V. Rotatable ball plug valve comprises a ball valve member 5 supported against the downstream slat 7 by a spring 9. The valve member has a key and slot connection with an operating stem 10 which allows it to take up its position on the downstream seat. The valve member may be clear of an upstream seat 8 excepting under reversed pressure conditions. The stem 10 is located axially, e.g. by a sleeve as shown between the handle 12 and body 1, so that it cannot push downwardly and displace the valve member. A stop plate 16 on the key end of the stem co-operates with an abutment 17 on the body and limits the rotation to 90 degrees. The stem may seat conically at 26 in a bonnet 21 to provide frictional resistance preventing accidental rotation of the valve member. The stem is sealed by an 0-ring 22. In another embodiment a ring (41), Figs. 6 and 7 (not shown), seating on the ball constitutes an abutment for the spring.
