Definitions
- the present invention relates to an apparatus for dispensing liquids, in particular readily vapourisible liquid fuels, e.g. gasoline. It relates in particular to apparatus comprising a product storage vessel, and a dispensing column (e.g. a petrol pump) with the dispensing column and the product storage vessel being connected by a product supply pipe which is not in an easily accessible position. Thus the product pipe may be buried in the ground.
- a dispensing column e.g. a petrol pump
- vapourisible liquids such as gasoline
- a product storage tank into another container, for example the fuel tank of a car
- vapourised liquid from the container into which the liquid is dispensed. It is desirable to reduce the emissions of such vapours and gases into the atmosphere.
- DE 36 13 453 A discloses an apparatus in which a gas return line is located within the product supply hose of a gasoline dispenser (petrol pump). The gas return line is then led from the dispensing column (petrol pump) and is led into the gas space in the product storage vessel.
- US-A-3016928 is concerned with providing a device which can be installed in existing fuel gravity or pump lines. However, the disclosure is concerned with devices which are installed in vertical fuel pipes, and a central gas return pipe runs all the way through the flexible and refuelling hose to the storage tank.
- US 3016928 discloses a device for extracting gases and vapours from liquid fuel storage containers. A gasoline dispensing column (“pump”) is shown which has a gas return line within a fuel supply pipe which extends vertically downward into a storage tank.
- pump gasoline dispensing column
- an apparatus for dispensing a liquid product in particular a readily vapourisable liquid fuel
- which apparatus comprises a product storage vessel, a dispensing column, a product supply pipe which is not readily accessible and which connects the storage vessel and the dispensing column, and a gas return line connecting the dispensing column and the storage vessel, which gas return line opens into the dispensing column and the storage vessel at other places than the product suppply pipe, and part of which gas return line runs inside the product supply line is characterised in that said product supply pipe (7) is provided with sealed inlet and outlet members (13,14,15) for the gas return line.
- the present invention is particularly useful when there is not vertical straight line connection between the dispensing column and the storage vessel, for example when there is a horizontal portion of the supply pipe which is not easily accessible.
- the apparatus of the present invention is preferably provided with a return pump in the gas return line because this makes possible the use of a gas return line with a smaller diameter, which in general will be of the order of 8 mm internal diameter and thus does not significantly reduce the free cross-section of the product pipeline.
- the installation of the gas return line is substantially simplified because it is merely necessary to provide the product pipeline at the inlet and outlet locations with corresponding inlet and outlet devices. These are formed from a tubular intermediate piece with an inlet or outlet connector provided with a seal. The connectors are provided in the protected area of a dispensing column and in the access pit of the storage vessel. The requirements for the protection of the gas return line are thus relatively small because it does not lie free in the ground and is thus protected from unexpected mechanical or chemical attack. It can thus be in the form of a hose of flexible and product resistant plastic, for example Perbunan (butyl rubber) or of PTFE.
- the gas return line may be electrically conducting, either because the material from which it is made is conductive or because it contains a conductive metal insert.
- the gas return line is highly desirable for the gas return line to be undivided in the region of the inlet and outlet device. Preferably it is undivided throughout the product pipe, in order not to influence the reliability of the apparatus.
- the inlet and outlet devices on the product pipe then merely need to be arranged for sealing of the periphery of the gas return line, while any necessary pipe connections for the gas return line can be arranged outside the product supply pipe and the inlet and outlet devices. In this way the possibly sensitive regions of the gas return line are easily accessible for checking and maintenance.
- the introduction of the gas return line into the product supply pipe may be carried out either directly by insertion of the flexible gas supply line or by means of a spiral, or, for pipe runs with frequent changes in direction, with a pulling wire. If it is not easy to push the gas return line, the spiral or the pulling wire through the product supply pipe on account of the number of changes of direction then the free end of the return pipe or a pulling means attached to it can be connected to a pig which can be forced through the product pipe under pressure.
- the invention will now be described with reference to the drawing which is a schematic representation of the apparatus of the invention.
- Buried in the ground (1) is the storage vessel (2) for easily vapourisable liquid fuel.
- the vessel (2) has an upwardly extending portion (3) through which access may be obtained to the vessel.
- This upwardly extending portion (3) is accessible within an access pit (4).
- From portion (3) of the tank there extends a portion (5) of a fuel supply pipe forming part of the vessel (2).
- This is connected by an expansion compensator or distance piece (6) to a buried section (7) of the fuel supply line (7).
- the fuel supply line (7) ends in a pit (8) under a dispension column (9) and is connected with the internal parts of the dispensing column (9) by means of an expansion compensator (10).
- Gas return line (11) leads from the dispensing column (9) through return pump (12) back to the vessel (2).
- the fuel supply line and the gas return line are connected with different internal parts of the dispensing column (9) they leave from different parts of the dispensing column. They also open into different parts of the storage vessel.
- the product supply line (7,5) opens into the liquid space in the vessel while the gas return line opens into the gas space in the upwardly projecting portion (3).
- connecting pieces (13,14) are connected which are formed as inlet and outlet devices for the gas return line (11). They have a connecting piece (15) through which the gas return line, consisting of flexible plastic is led and which is sealed around the periphery of this line by suitable sealing means.
- the gas return line therefore needs to have no break at this place. It can if desired lead in a single undivided length from the dispensing column to the storage vessel. It can also be provided with a connector (16) outside the fuel supply pipe (7). This is for example appropriate if the return line on the grounds of mechanical resistance is of a different material from that inside pipe (7).
- the tube connector (16) can if desired be mechanically supported by the connector (15) and for this purpose may be connected to it, which however does not alter the principle of the undivided passage of the return line through the connectors or their seals.
