Apparatus for the filling of a tank with a volatile liquid includes a delivery pipe having a pair of tubular distribution members hinged to the lower end thereof. The distribution members may hinge between an insertion position where they lie parallel to the axis of the delivery pipe and a deployed position where the members are co-axial but extending normally to the axis of the delivery pipe. When in their insertion position, the distribution members as well as the delivery pipe may be passed through the conventional fill-pipe of the tank, the distribution members then hinging to their deployed position as the lower end of the delivery pipe approaches the bottom of the tank. The delivery pipe is in communication with the interior of the distribution members when the latter are in their deployed position. Holes are formed along the length of each distribution member so that volatile liquid fed down the delivery pipe in the tank is distributed throughout the area of the tank, so minimizing turbulence of liquid already in the tank.
Filling apparatus for use in the filling of an essentially closed tank with a volatile liquid, while minimizing any resultant turbulence in the tank comprising a delivery pipe adapted to be inserted generally vertically through an opening into the tank, and at least one distribution member being hingedly connected about a transverse axis to the lower end of the delivery pipe so as to be movable between an insertion position where the or each distribution member extends parallel to the pipe and a deployed position where the or each distribution member extends generally radially away from the pipe, the or each distribution member being in the form of a duct arranged so that when in its deployed position liquid flowing along the delivery pipe may then flow along the duct defined thereby, and exit from the distribution member along the length thereof.
A method of filling of an essentially closed tank with a volatile liquid using apparatus including a delivery pipe having at least one distribution member being hingedly connected about a transverse axis to the lower end of the pipe so as to be movable between an insertion position where the or each distribution member extends parallel to the pipe and a deployed position where the or each distribution member extends generally radially away from the pipe, the or each distribution member being in the form of a duct arranged so that when in its deployed position liquid flowing along the pipe may then flow along the duct, which method comprises the steps of lowering said pipe through an opening in the tank with the or each distribution member in said insertion position until the lower end of the or each distribution member touches the bottom of the tank, continuing to lower the pipe so that the or each distribution member is moved from its insertion position to its deployed position and bears on the bottom of the tank, and then supplying liquid to the delivery pipe so that the liquid flows along the pipe and then into the or each deployed distribution member, and exit from the distribution member along the length thereof.
An essentially closed tank for a volatile liquid, which tank includes a fill-pipe extending generally vertically into the tank through an opening in an upper part thereof, and a distribution member secured to the lower end of the fill-pipe so as to extend generally radially away from the fill pipe, the distribution member being in the form of a duct which is in communication with the interior of the fill-pipe so that liquid flowing along the fill-pipe may then flow along the duct defined by the distribution member, said member being configured to permit discharge therefrom of liquid supplied thereto from the fill-pipe along the length of the distribution member.
