Abstract

1,245,109. Pipe joints; valves. J. A. CANNINGS. 7 Nov., 1969 [7 Nov. 1968], No. 52816/68. Headings F2G and F2V. A resilient fluid-tight sealing ring 16 has two frusto-conical surfaces 30, 32 forming two coaxial lines of contact 34, 36 with a spherical surface 18, the ring material thickness, normal to the contact, being uniform along each line of contact and equal for each line of contact. The sealing ring 16 may be of P.T.F.E., or a polyimide, and is held in a metal body 10 with a passage 42 for a coolant fluid. The seal 16 and body 10 may be used in a swivel pipe joint or a ball valve. The body 10 has, at the other end, provision for a resilient seal 12 for a flat surface 14, the seal being urged against the surface by a frusto-conical spring 24, and also by fluid pressure, provision being made for fluid to enter the seal between the body and a seal flange 26.
