DESCRIPTION:
BRIEF SUMMARY
This invention concerns a liquid delivery nozzle.
The liquid delivered by the nozzle may be water.
An object of the invention is to provide a liquid delivery nozzle which may be constructed and so used as to deliver water in the form of stream of drops of which the majority are large drops meaning water drops each having a diameter of at least substantially 0.7 m.m. or greater.
According to the invention a liquid delivery nozzle comprises a tube for liquid to be introduced into one end of said tube and emerge from another or output end of the tube, a dispersion plate of dish-form being concave on one side of said plate, said output end facing said concave side of the plate for emergent liquid to be directed against the concave side, said dispersion plate being impervious, and and said concave side being substantially smooth and continuous.
In use the liquid may be water, and the nozzle may be disposed with its tube in a substantially vertical attitude and with the concave side of the plate facing upwards so that water emerging from the output end of the tube hits the plate and then travels over the concave surface of the plate to a periphery of the plate for which periphery the water is discharged in said relatively large drops.
We believe that such water drops delivered continuously in the form of a stream or curtain can prevent, suppress or impede the occurrence, development, progress or effect of an explosion of explosive gas, vapour, or dust.
A plurality of spaced nozzles may be mounted at/or in the vicinity of an area where explosive material, for example combustible gases or liquids, is being handled, or stored for water to be delivered to the nozzles in the event of a potentially explosive condition being detected. Preferably the nozzles are mounted at elevated positions. The nozzles may be used at oil or fuel gas drilling or production platforms or installations, oil refineries, fuel gas production sites, at storage sites of explosive or inflammable gas or liquid, and at chemical plants. The gas referred to above may be natural gas.
Various aspects of the invention will now be further described with reference to the accompanying drawings in which:
FIG. 1 is a fragmentary view, partly in section on line I--I in FIG. 2, of an embodiment of a liquid delivery nozzle formed according to the invention;
FIG. 2 in a section on the line II--II in FIG. 1;
FIG. 3 in an inverse plan view in the direction of arrow III of the delivery nozzle in FIG. 1;
FIG. 4 is a representation of the delivery nozzle in FIG. 1 illustrating how liquid supplied to delivery nozzle is delivered therefrom;
FIG. 5 is representation of the nozzle in FIG. 1 to illustrate ranges of dimensions which component parts or features of a delivery nozzle, formed according to the invention, may have;
FIG. 6 is a fragmentary view, partly in section on line VI--VI in FIG. 7, of another embodiment of delivery nozzle formed according to the invention;
FIG. 7 is a view of the delivery nozzle in FIG. 6, in the direction of arrow VII;
FIG. 8 in view, partly in section and similar to FIG. 1, of yet another embodiment of liquid delivery nozzle formed according to the invention, and wherein the dispersion plate is shown mounted on a support and the tube is shown connected to a supply of liquid;
FIG. 9 is a diagrammatic plan view, partly in section, of a further embodiment of a nozzle formed according to the invention mounted on a partition or wall, and
FIG. 10 is a diagrammatic representation of an explosion suppression and/or fire extinguishing arragement including liquid delivery nozzles each as shown in FIGS. 1 to 3.
In the following description like reference numerals refer to like or comparable parts.
With reference to FIGS. 1 to 3, a liquid delivery nozzle 2 comprises a jet or substantially cylindrical tube 4 into which a liquid, for example water, under pressure is supplied at one end to emerge at an output end 6.
The output end 6 faces towards a concave side 8 of a dispersion plate 10 of curved, dish form and having a substantially circular periph
