Abstract

1,212,520. Valves. BRYAN DONKIN CO. Ltd. 10 Dec., 1968 [12 Dec., 1967], No. 56382/67 Heading F2V. In a valve which is adapted to regulate pressure when such pressure lies between predetermined upper and lower values and to cutoff flow when such pressure rises above, or falls below the predetermined values, regulation of pressure is effected by a valve member 80 which co-operates with a seat formed about a port 72 whilst cut-off is effected by a valve member 84 which co-operates with a seat formed about a port 74, the two valve members being interconnected by a spindle 83 and the two ports interconnected by the bore formed in a plug 70 which is disposed in a wall 66 separating the inlet 62 from the outlet 64. An extension 60 of the spindle 83 is connected, through an operating lever 92, a trip lever 94 and a link 96, to a diaphragm 32, the underside of which is subjected, via ports 65, to pressure at the outlet, the operating lever being pivoted at 116, and the trip lever being pivoted to lever 92 at 102 and to link 96 at 100. A spring 104 extends between the pivot point 100 and a pin 106 and, under normal regulating conditions, extends below pivot point 102. With the fluid pressure within the predetermined valves, the pressure at the outlet 64 acts on the diaphragm which in turn correspondingly actuates valve member 80. Upon such pressure falling below the lower predetermined value, spring 47 moves the diaphragm downwardly and hence, via the link and levers, moves valve member 84 on to its seat, Fig. 3 (not shown). In the event of the pressure rising slightly above the upper predetermined value, diaphragm 32 moves upwardly so causing lever 92 to pivot in an anticlockwise direction and hence valve member 80 to be seated, Fig. 2 (not shown). A further pressure increase results in spring 104 moving to the other side of pivot 102 and hence, by virtue of the arrangement of pivot points and the spring tension, forcing cut-off valve member 84 on to its seat, Fig. 4 (not shown). Re-setting of the valve, subsequent to valve member 84 being seated, is effected by appropriate manipulation of diaphragm stem 40.
