Embodiment Construction

[0130] figure 1 and figure 2 Side and three-dimensional views of different embodiments of a filter 10 according to an aspect of the present invention are shown.

[0131] The filter 10 is formed by a duct 12 extending from a first end to a second end. An inlet 18 is located through the first end of the duct, and the inlet has a cross-sectional area which is smaller than that of the outlet 16 of the duct 12 and which in use is generally smaller than the outlet of the associated nozzle.

[0132] The inlet 18 also has a cross-sectional area that is smaller than the cross-sectional area of ​​the bore of the conduit 12 .

[0133] The slot 20 extends longitudinally along a first portion of the sidewall 13 of the duct 12 from the first end of the duct to the threaded bushing 22 . The width of the slots is 1 mm and above, and in this example the slots have a suitable length where two of the slots are equal to the flow required to produce the corresponding K-factor of the associated...

Abstract

A filter is disclosed that includes a conduit extending from a first end to a second end and having a bore with an internal cross-sectional area. The duct includes an inlet having an inlet cross-sectional area positioned through the first end of the duct. The duct also includes an outlet having an outlet cross-sectional area, wherein the inlet cross-sectional area is smaller than the outlet cross-sectional area, and thus sufficiently small debris entering the inlet will tend not to block the larger outlet. The filter also includes a plurality of additional inlets, usually slots, in the pipe between the exterior of the pipe and the holes. In a preferred embodiment, the first end portion may be conical and in particular dome-shaped. This helps direct the debris towards the outside of the pipe where it is less likely to be sucked into the filter and potentially clog the filter or downstream components such as nozzles. The filter can be attached to lines and nozzles.

Description

technical field [0001] The invention relates particularly, but not exclusively, to filters as part of, or for nozzles connected to, a pipeline. Background technique [0002] Fluid flow systems, such as sprinkler systems, are widely used in onshore and offshore installations, such as oil and gas platforms, to contain or suppress fires. During the operation of the sprinkler system, it is likely that scale, debris and other contaminants will accumulate and become a problem. Scale is usually formed by the precipitation of inorganic compounds such as calcium carbonate or calcium sulfate from the water due to pressure and / or temperature changes in the pipeline. Corrosion in pipelines can build up along the inner walls of the pipes and also generate debris that enters the system. Sea life can also cause clogging problems. Salt can also crystallize and cause clogging problems. [0003] Due to this accumulation, the nozzles of the sprinkler system are often clogged and this can r...
