Abstract
538,495. Valves. GRAHAM, J., GRAHAM, D. A., and AULD & SONS, Ltd., D. April 22, 1940, No. 7256. [Class 135] An isolating valve of the kind wherein a balanced or substantially balanced valve member is operatively connected to a floating disc actuator arranged in a passage leading to a relief valve, is so arranged that the joint between the main casing and the relief valve casing is not subjected to the pressure on the delivery side of the balanced valve. In the form shown the balanced valve comprises a double-beat valve with slightly unequal beats f, g. The valve spindle h is guided by a sleeve h<SP>1</SP> supported by integral webs h<SP>2</SP> and is directly connected to the actuating disc i, the upper and lower faces of which incline towards each other from the centre to the periphery. The seat l for the relief valve surrounds the upper end of the cylindrical passage j housing the disc i. The valve m is loaded by a spring o adjusted by a screwed member t having a flange t<SP>1</SP> with an even number of holes adapted to co-operate with a flange u on the relief valve casing having an uneven number of holes, one pair of said holes being adapted to receive a locking pin v. The valve m may be loaded by weights or a weighted lever. Sediment is received in a cup k detachably secured to the lower part of the casing.
