摘要 |
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. |
