Abstract

1477173 Sliding gate valves FLOGATES Ltd 16 May 1975 [15 June 1974] 26633/74 Heading F4B A sliding gate valve 10 with an orifice 11 for controlling the flow of molten metal from a teeming passage with axis denoted by line 12, is connected for position control to a fluid actuator unit 15 comprising two rams 20, 21 arranged in line and sharing a common housing 22. The piston-rod 29 of one ram is secured to a fixed mounting and the piston-rod 30 of the second ram is secured to the gate valve 10. Fluid supplied to the rams may be controlled by solenoid valves 17, 18 operated by a pushbutton consol 32. With the piston-rod 30 of ram 21 fully extended, the orifice 11 is required to centre on the teeming passage axis 12, and thus datum-setting is established by adjusting cylinder housing 22 relative to ram 20. From the datum-setting ram 21 is operated to open and close the gate valve as required. If a stage is reached when the orifice 11 is eroded and normal operation of ram 21 is unable to close the teeming passage, cylinder housing 22 is moved relative to the ram 20 to shift the actuator unit 15 as a whole to give emergency valve closure so that area 34 of the slide plate covers the teeming passage. For installation when the line of action of the unit 15 is not coincident with the direction of movement of the slide plate 10, a directionchanging coupling such as a bell-crank (40), Fig. 4 (not shown), may be employed.
