Equipment for bottom loading of liquid products
First Claim
1. Apparatus for supplying a liquid product to a pipe connected to the bottom of vessel from a flexible conduit connected to a distribution station, said apparatus comprising a tank valve including a hollow body constituted by two parts inclusive of a rear part adapted for connection to the pipe connected to the bottom of the vessel and a front part provided with a large aperture and having coupling means, a flap valve for closing said aperture, means for actuating said flap valve comprising a connecting rod supporting said flap valve, a profiled lever forming a knuckle joint with said connecting rod, an operating shaft rotatably supported by said hollow body, a gusset connected to said operating shaft, said profiled lever being pivotably connected to said gusset, an operating lever extended externally of said body and connected to said shaft to rotate the same,a coupling for connection with the coupling means of the tank valve and the flexible conduit connected to the distribution station, said coupling comprising a main casing connected to the flexible conduit, a connecting nose on said casing for lockable connection with the coupling means of the body of the tank valve, a rear casing including mechanical and hydraulic safety means, a closure member in said casing for controlling flow of liquid product from the flexible conduit to the tank valve and means for actuating said closure member by remote control,said flap valve being applied against said closure member in coupled and closed position of the tank valve such that upon separation of the tank valve from the coupling at the end of supply of liquid to the vessel only a negligible guantity of liquid product is released.

Abstract
Apparatus for supplying a liquid product to a pipe connected to the bottom of a vessel from a flexible conduit connected to a distribution system comprising a tank valve connected to the pipe and a coupling connected to the flexible conduit and adapted for connection to the tank valve. The tank valve includes a hollow body one part of which has a large aperture and a coupling mechanism for attachment with the coupling; a flap valve is disposed in the body for closing the aperture and the flap valve is connected via a linkage to an external operating lever; the coupling has a main casing with a connecting nose for lockable connection with the coupling mechanism of the body of the tank valve. A closure member is disposed in the casing for controlling flow of liquid product from the flexible conduit to the tank valve and a hydraulic ram acts on the closure member along with a cartridge having three springs of staggered force to provide the closure member with three stable positions of increasing opening.

8. Apparatus for supplying a liquid product to a pipe connected to the bottom of vessel from a flexible conduit connected to a distribution station, said apparatus comprising
a tank valve including a hollow body constituted by two parts inclusive of a rear part adapted for connection to the pipe connected to the bottom of the vessel and a front part provided with a large aperture and having coupling means, a flap valve for closing said aperture, means for actuating said flap valve including an operating lever, a coupling for connection with the coupling means of the tank valve and the flexible conduit connected to the distribution station, said coupling comprising a main casing connected to the flexible conduit a connecting nose on said casing for lockable connection with the coupling means of the body of the tank valve, a rear casing including mechanical and hydraulic safety means, a closure member in said main casing for controlling flow of liquid product from the flexible conduit to the tank valve, a hydraulic ram for actuating said closure member, a cartridge in said casing for returning said closure member to initial position including three springs of staggered force having limited travel such that increase of pressure in the ram gives the closure member three stable positions of increasing opening, said flap valve being applied against said closure member in coupled and closed position of the tank valve such that upon separation of the tank valve from the coupling at the end of supply of liquid to the vesel only a negligible quantity of liquid product is released.
