Title: Improvements in or relating to actuating mechanisms for flap and slide valves, more particularly for tankers
IPC: F16K31/124
Filed: 1968-06-04
Abstract: 1,235,172. Valves. O. KRACHT, J. KRACHT and L. KRACHT, [trading as KRACHT PUMPEN-UND MOTORENFABRIK K.G.]. 4 June, 1968 [1 June, 1967; 19 Jan., 1968], No. 26434/68. Heading F2V. An arrangement for actuating a ship's slide valve 42, comprises an operator 22, a relay 48, and an hydraulic cylinder 40, the cylinder being operatively connected to the valve. In the state of the arrangement shown, the operator valve 23 is in its " stop position O " in which communication between supply and exhaust lines 6 and 10 respectively and the arrangement operating line 28 is broken, the relay plunger 52 is maintained by static pressure in line 28 acting within chamber 46 and in opposition to adjustable spring 54 in its equilibrium position, in which position communication between relay supply and exhaust ports 60 and 62 respectively and relay working port 58 is broken, cylinder chamber 43 is pressurized, and valve 42 is closed. Upon placing the operator valve 23 in its " open position I ", the pressure supplied to line 28 moves plunger 52 to the right so placing cylinder chamber 43 in communication with relay exhaust 62, with cylinder chamber 41 being simultaneously pressurized as a result of which valve 42 is caused to move towards its fully open position. Such movement is maintained as long as operator valve 23 is in its open position, but can be terminated at will, and before the fully open position is reached by placing valve 23 in its stop position. To reclose valve 42, operator valve 23 must be placed in its " close position II " in which line 28 is depressurized, plunger 52 consequently moved to the left, and cylinder chamber 43 placed in communication with relay supply 60. The operator 22 can be by-passed when it is desired to close valve 42 by actuating a valve 32 which then places line 28 in communication with a low pressure line 34. A pressure gauge 29, or a combined pressure and volume gauge, (128, Fig. 4, and Figs. 6-12, not shown), may be provided on line 28 in order to indicate the state of the arrangement and the position of the valve. Figs. 4 and 5, not shown, depict the application of the arrangement to a different slide valve and to a butterfly valve respectively.
