Abstract
1331973 Valves HYDROMETER GmbH 1 Dec 1970 [3 Dec 1969] 57031/70 Heading F2V A valve for controlling large flows from a main meter connected at 11 and for connection to a secondary meter at 12 for small flows comprises a valve disc 52 biased to closed position by springs 29 acting through levers 28 and rollers 32 co-operating with inclined surface 57 and opened by differential pressure thereacross. In operation when the differential pressure increases a cylinder 82 will move relative a fixed piston 81 to the right against a spring bias 88 and the valve disc will also move abruptly to the right when the differential pressure reaches a predetermined value, the rollers 32 running along the cylindrical surface 58 and no longer applying a bias to the disc 52. After the valve has opened the differential pressure will decrease and the cylinder 82 will move to the left and through radial pins 67 and bars 63 will move an auxiliary valve disc 64 to an open position in which flow takes place through holes 61 in the disc 52. Spring-loaded balls 74 engaging in recesses 75 lock the disc 64 in open position. Cylinder 82 abutting the disc 52 will move the latter according to the pressure differential thereacross until this drops to such a value that the disc 52 approaches seat 46 and closes off flow by means of seal 48 engaging cylindrical surface 54. At this point the spring bias 24 again acts on the disc 52 since rollers 32 are positioned on inclined surface 57. Flow still takes place through holes 61. When the pressure differential drops to the predetermined value the spring bias 29 moves the disc abruptly to the left so that seal 56 abuts seat 46 and simultaneously disc 64 abuts member 23 to move the balls 74 out of recesses 75 and allow the disc to close under the bias of weak spring 68 acting between disc 52 and radial pins 67. In modifications the spring bias applied by rollers acts on a hub of the disc 52 or is applied by radially mounted springs, the spring bias acting on cylinder 82 is disposed within the cylinder, and the auxiliary valve disc is dispensed with, the final closing of the valve being determined by flow between co-operating flanges on the housing and the cylindrical surface of the disc 52.
