Abstract

771,562. Valves. BRITISH PETROLEUM CO., Ltd., and FRASER, D. S. D. Dec. 15, 1954 [Dec. 22, 1953], No. 35600/53. Class 135. A rotary cylindrical plug valve comprises a body A, Fig. 1, having radially disposed branches B, X<SP>1</SP>, X<SP>2</SP> and a ported tubular valve member C split longitudinally at C<SP>1</SP> and formed on its inner periphery with lugs F<SP>1</SP>, F<SP>2</SP> and a recess G<SP>1</SP> engageable with arms H<SP>1</SP>, H<SP>2</SP>, H<SP>5</SP> of a member E keyed to an operating spindle J. On rotation of the spindle the arm H<SP>5</SP> engages the recess to apply a rotational force to the valve member whence the claw-like end of one or other of the arms H<SP>1</SP>, H<SP>2</SP> engages its associated lug, tending to reduce the width of the split and move the valve member away from the body to permit of its easy rotation. To replace, for example, a faulty safety valve in a plant whilst the plant is still working, two such valves 2, 7, Fig. 4, are connected together by a pipe 5 provided with a safety valve 4. The valve 2 being mounted on a pressure vessel 16 and the valve 7 on an exhaust manifold 13. To replace the safety valve, an arm 11 is moved to rotate an operating spindle 10 common to both valves to isolate the blanked branches 8, 9 from the vessel 16 and manifold 13 respectively. The blanks may then be removed and a replacement pipe and safety valve fitted. The arm 11 is then moved to isolate the branches 3, 6 from the vessel 16 and the manifold 13, whence the faulty valve and pipe may be removed and the ends of the branches 3, 6 blanked.
