ES191280U - Discharge device for tankers. (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Discharging device for tanks, essentially characterized in that it is constituted by a tubular receptacle provided inferiorly with a chamber provided with side holes, inside which receptacle is vertically displaced the overflow conduit, which comprises in its lower area a washer located above the sealing gasket and inside said lower chamber, the latter comprising an articulated anchorage on its wall a movable stop provided with a float to the outside of said chamber, which stop is located at a higher height than the aforementioned washer, so that by actuating a pneumatic device anchored in the upper area of the receptacle, the overflow conduit moves vertically upwards causing the opening of the discharge valve, at which time said washer exceeds in height the mobile stop, preventing the latter its fall and consequently the closure of the discharge valve, until the tank is empty and the float loses contact with the liquid, whereupon the said stop recovers a position out of reach of the washer, allowing the fall by gravity of the overflow conduit to be established again the closing of the discharge valve.
