Abstract
A fluid delivery device for fixing to and delivering a fluid into a pressurized pipe, the device operable for restricting a flow of fluid through the pipe, thereby generating a restricted flow region within the pipe, the device including a delivery conduit arranged to open into the restricted flow region.
Claims16
A fluid delivery device for fixing to and delivering a fluid into a pressurized pipe, the device comprising flow restriction means operable to restrict a flow of fluid through the pipe, thereby generating a restricted flow region within the pipe at the position of the flow restriction means, as compared to an unrestricted flow upstream of the device, the device further comprising a delivery conduit arranged to open into or proximal to the restricted flow region, wherein the flow restriction means is adjustable so as to alter the amount of restriction of the flow within the pipe, wherein the flow restriction means comprises an aperture through which the fluid in the pipe may travel, and wherein the aperture is generally funnel shaped.
A method of delivering a fluid into a pressurized pipe, the method comprising adding flow restriction means within the pipe to thereby generate a restricted flow region within the pipe at the position of the flow restriction means, as compared to an unrestricted flow upstream of the flow restriction means, and arranging a delivery conduit to open into or proximal to the restricted flow region, wherein the flow restriction means is adjustable so as to alter the amount of restriction of the flow within the pipe, wherein the flow restriction means comprises an aperture through which the fluid in the pipe may travel, and wherein the aperture is generally funnel shaped.
A method of attaching a fluid delivery device to a pressurized pipe, the method comprising:
- arranging a saddle about a pressurized pipe, the saddle comprising an access point to allow a hole forming apparatus access to the pressurized pipe,
- arranging the hole forming apparatus about the access point of the saddle, the hole forming apparatus being substantially sealed with the saddle via a first seal;
- using the hole forming apparatus to form a hole in a wall of the pressurized pipe;
- forming a secondary seal in the access point at a position between the formed hole and the first seal;
- and
- removing the first seal and inserting flow restriction means of the fluid delivery device into the access point of the saddle, thereby forming a tertiary seal wherein the flow restriction means is adjustable so as to alter the amount of restriction of the flow within the pipe, wherein the flow restriction means comprises an aperture through which the fluid in the pipe may travel, and wherein the aperture is generally funnel shaped.
