Description

(54) WATER DISCHARGE NOZZLE (71) We, BRITISH STEEL CORPORATION, a Corporation incorporated and existing under the Iron and Steel Act 1967 whose principal office is at 33 Grosvenor Place, London, S.W.l do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to water discharge nozzles. It is particularly concerned with nozzles suitable for use with water under high pressure to clean deposits from contaminated surfaces. One application of the nozzle is described in our co-pending British patent specification 52625/76. Serial No. 1 595 179. The nozzle may, however, be suitable for other applications.
According to the invention there is provided a water discharge nozzle comprising a nozzle head having a plane end face, a single discharge orifice located in the end face and opening to a passage extending through the nozzle head, at least two slots formed in and extending across the end face of the nozzle head intersecting at said orifice so as to provide in use at least two intersecting flat fan shaped water discharges, the diameter of the discharge orifice being greater than the width of any of the slots.
The slots are preferably equi-angularly spaced from one another such that the flat fanshaped discharges provided in use are also equiangularly spaced. The orifice is preferably centrally located in the end of the nozzle head.
The slots may be U-shaped in cross-section.
The slots may be flat bottomed when viewed in cross-section. Alternatively other configurations such as a V-shape may be employed.
At least one of the slots may decrease in depth towards the perimeter of the end face of the nozzle head. Alternatively, at least one of the slots may have a constant depth along its length. Where the slot depth varies, it may vary as an arc of a circle when seen in cross-section.
One or more of the slots may extend continuously to the perimeter of the end face of the nozzle head.
An embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a water discharge nozzle; Figure 2 is a side elevation of the nozzle of Figure 1; Figure 3 is an end elevation of the nozzle of Figure 1, and Figure 4 is a section on line IV-IV of Figure 3.
The water discharge nozzle shown comprises a cylindrical head 10, a central portion 11 having a hexagonal periphery of diameter greater than the head 10, and a threaded portion 12 at the opposite end of the nozzle from the head 10.
The head 10 has a plane end face with a centrally located orifice 17. The orifice 1 7 connects with a channel 18 which extends along the central axis of the head 10 along the length of the nozzle.
Two mutually perpendicular slots, 15 and 16 respectively, are cut into the end face of the head 10 such that the slots 15 and 16 intersect at the orifice 17. The slots 15 and 16 are of varying depth along their length, each slot being cut as the arc of a circle when seen in cross-section, as in Figure 4, with the deepest part of each slot at the orifice 17. Both slots are U-shaped and extend about four fifths across the diameter of the head 10.
The threaded portion 12 is adapted to engage with a hollow stem (not shown) which in use supplies water under high pressure to the nozzle. By high pressure it is meant between 1000 and 10,000 psi. Under these conditions two flat fan-shaped discharges having a common axis and spaced at equal angles of ninety degrees to one another are produced by the nozzle.
WHAT WE CLAIM IS: 1. A water discharge nozzle comprising a nozzle head having a plane end face, a single discharge orifice located in the end face and opening to a passage extending through the nozzle head, at least two slots formed in and extending across the end face of the nozzle head intersecting at said orifice so as to provide in use at least two intersecting flat fan-shaped water discharges, the diameter of the discharge orifice being greater than the width of any of the slots.
2. A water discharge nozzle as claimed in

2. A water discharge nozzle as claimed in claim 1 in which the slots are equi-angularly spaced from one another such that the flat fanshaped discharges provided in use are also equiangularly spaced.
3. A water discharge nozzle as claimed in claim 1 or claim 2 in which the orifice is centrally located in the end face of the nozzle head.
4. A water discharge nozzle as claimed in any preceding claim in which the slots are Ushaped in cross-section.
5. A water discharge nozzle as claimed in any of the claims 1 to 3 in which the slots are flat-bottomed when viewed in cross-section.
6. A water discharge nozzle as claimed in any preceding claim in which at least one of the slots decreases in depth towards the perimeter of the end face of the nozzle head.
7. A water discharge as claimed in claim 6 in which the slot depth varies as an arc of a circle when seen in cross-section.
8. A water discharge nozzle as claimed in any preceding claim in which at least one of the slots extends continuously to the perimeter of the end face of the nozzle head.
