Abstract:
The present invention relates to a spray head for effective fire fighting. The spray head according to the present invention provides a uniform distribution of a fluid, such as pressurised water, over a relatively large area. To achieve this, the spray head comprises a body defining a central axis and further comprising a fixation structure for fixing the spray head to a fluid supply system, a fluid inlet, directing fluid in a first direction, a plurality of outlet holes arranged around the central axis, and a flow path between the inlet and the holes, wherein a first set of holes are located in such a way, that the fluid is leaving the first set of holes in a second direction opposite to the first direction and wherein the body further comprises an arrangement for holding a fire actuation member.
Abstract:
A residential or commercial sprinkler system is provided wherein the sprinkler heads and piping distribution network are provided with a relatively low pressure fire suppressant liquid in place of pneumatic pressure, which is typical, and control valve keeps fire suppressant supply pressure from entering the discharge sprinkler system at design discharge pressure until a fire detection system detects a fire condition. Upon the detection of a fire condition, a control valve is opened to provide the sprinkler heads and piping distribution network with a fully pressurized supply of fire suppressant. Also in the case of electric control power loss the system will operate from loss of outlet supervised pressure releasing sprinkler liquid suppressant to the discharge system of closed fused sprinklers.
Abstract:
A pendant sprinkler preferably includes a body having an inner surface defining a passageway. The passageway includes an inlet and an outlet spaced apart along the longitudinal axis and defines a K-factor of about 5. The sprinkler also includes a closure assembly adjacent the outlet to occlude the outlet and a thermally responsive support means for maintaining the closure assembly adjacent the outlet. Also provided are means for distributing a flow of fluid over a protection area ranging from about 144 square feet to about 400 square feet, the fluid distribution having a density of at least 0.05 gallons per minute per square foot (0.05 gpm/ft 2 ) so as to define a range of minimum operating pressures ranging from about seven pounds per square inch to about seventeen pounds per square inch (7-17 psi.) and a range of minimum operating fluid flows ranging from about thirteen gallons per minute to about twenty gallons per minute (13-20 gpm.). The sprinkler preferably includes a thermally responsive plate means for maintaining a minimum spacing between the outlet and the means for distributing.
Abstract:
A fire extinguisher comprises a vessel (2) containing extinguishing agent and a nozzle (3) arranged, in use, to deliver the extinguishing agent to a scene. The extinguisher further comprises a sensor (5) for receiving infrared radiation from the scene. Data from the infrared sensor may be processed and used to derive a visual image or other visual indication of infrared radiation from the scene. Alternatively, the data may be used to provide an audible and/or tactile signal to a user. The provision of an infrared sensor permits a user of the extinguisher to locate the centre of the fire and release extinguishing material in one operation. Previously, a user had to firstly locate the centre of the fire using imaging equipment, then put that equipment aside and take up the fire extinguisher, directing the nozzle approximately in the region of the fire.
Abstract:
A sprinkler head mounting assembly for attaching a sprinkler head (10) to a fluid distribution pipe (1), wherein the sprinkler head mounting assembly comprises a sprinkler head stem (12) connected to the sprinkler head, a flange (15) connected to the sprinkler head stem, a first clamp portion (30) designed to fit around a section of the peripheral surface of the pipe and to engage the flange to affix the sprinkler head to an opening (20) in the pipe, and a second clamp portion (40) designed to fit around the section of the peripheral surface of the pipe that is not covered by the first clamp portion, wherein the second clamp portion designed to engage the first clamp portion to form a substantially secure connection about the pipe.
Abstract:
The proposed invention concerns a sprinkler nozzle for the atomization of foam or water, in particular for the purpose of extinguishing fires. It comprises a head component provided with a channel which tapers in the direction of the supplied medium and has an inlet and outlet. It has a bridge which connects with the channel and has supports arranged at a distance from each other which join at the base, between which a support cone is situated on a distributor star. The distance between the channel outlet and the scattering pot is more or less equal to the distance between the outlet and inlet of the head. The generatrices of the conical tapering of the channel converge in the support cone. According to the invention, the support cone has a rebounding pot consisting of a cylindrical bore and an inner cone as the base. The generatrices of the channel converge in the rebounding pot and the surface of the distributor star encloses an angle alpha of 0-5 DEG and preferably 3 DEG with the vertical plane to the central axis of the nozzle.
