Definitions
- the invention relates to a spray head as defined in the preamble of claim 1.
- Prior-art spray heads known in fire-fighting technology include spray heads, especially sprinkler heads, provided with a valve element which, when in a non-activated state, blocks the liquid passage and when the sprinkler is activated upon being triggered, e.g. by a thermally activated ampoule being broken, assumes a position in which the extinguishing medium can flow into one or more nozzles.
- a sprinkler head of this type is disclosed in US patent 6,318,474.
- the nozzles are formed by making in a frame a first boring and a second boring, each nozzle being formed by these borings together.
- the first boring has a first diameter
- the second boring has a second diameter.
- the spray head produces medium mist very efficiently.
- the disclosed solution is demanding in respect of manufacturing technology and imposes restrictions regarding the dimensions of the first boring and the second boring on the one hand and, on the other hand, regarding their mutual orientations.
- the object of the present invention is to produce a completely new type of solution for use in conjunction with spray heads, in particular sprinkler heads, that will make it possible to achieve a structure improved in respect of manufacturing technology.
- Another object of the invention is to create a spray head whose properties can be varied according to need, e.g. in a manner optimized for each application.
- the invention is based on a concept whereby the frame of the spray head is provided with a second part, such as a sleeve part, the wall of which is provided with at least one opening, so that the opening in the second part and the opening arranged in the frame part together form at least one nozzle of the spray head.
- the second part may be provided with at least one opening formed in a desired manner, whose dimensions, shape and/or orientation can be formed and, if necessary, optimized according to the application.
- the second part may be formed to be movable.
- the spray head of the invention is characterized in that the spray head is provided with at least one second part with at least one opening formed in it, which opening together with the opening formed in the wall of the frame part forms a spraying nozzle.
- the spray head of the invention is additionally characterized by what is stated in claims 2 - 24.
- the solution of the invention has numerous significant advantages.
- the spraying properties of the spray head can be varied according to the application by using different combinations of frame and second part, such as sleeve part.
- the spray head of the invention is very reliable in operation. It has a very good structure in respect of manufacturing technology.
- the invention allows e.g. solutions in which the dimensions and/or orientations of the nozzle opening formed in the frame and of that formed in the second part differ considerably from each other. This makes it possible to achieve a considerably larger range of application and/or range of variation of nozzle properties than in the case of prior- art solutions, especially when compared to a nozzle head in which the openings, such as borings, formed by the nozzle are made in the same body, such as the frame of the nozzle head.
- the shape of the spray can be adjusted by varying the angle.
- the openings in the frame and in the second part may be oriented in mutually different directions not only in relation to the vertical axis of the spray head but also tangentially relative to each other.
- the solution of the invention permits several openings to be formed in the second part, which are in connection with, i.e. in the coverage area of the nozzle opening formed in frame of the nozzle head.
- the spray head By forming a connection between the different nozzles in the nozzle head, e.g. by forming a medium channel between the frame and the second part, it is possible to further extend the properties of the spray head.
- the medium channel can be effectively created e.g. by forming a groove in the second part or in the frame or in both.
- the spraying properties of the spray head can be further extended.
- Some of the openings function as nozzles, and those of the openings opposite which there is no opening in the second part, such as a sleeve, can now function as air supply openings.
- the second part such as a sleeve, may have a groove formed in the area opposite to the holes bored in the frame, so that at least some of the holes communicate with each other.
- every second hole functions as a nozzle whereas air flows in through the other every second hole when the nozzle func- tions like an ejector.
- the additional air supply holes make it possible to influence the shape and penetration of the spray discharged. Without supplementary air, the spray produced is e.g. broader and/or softer, whereas by using supplementary air e.g. a narrower and/or sharper spray is produced.
- the second part such as a sleeve
- the frame can be arranged to be movable relative to each other.
- the second part is formed to be movable in the frame between at least two positions. This makes it possible to arrange for structural features giving a particular spraying property to be in alignment with each other between the frame and the second part in a first position, and for structural features giving a different spraying property to be in alignment with each other in a second position. In this case, e.g. when the sprayed medium has a higher pressure, the spray head can be arranged to have different properties than if the pressure of the sprayed medium were lower.
- the medium pressure and a counter-element for it such as a pre-tensioning element, especially a spring element
- a sleeve element as the second part, a very advantageous solution is achieved.
- a throttle element in the sleeve element and using a counter-element, a very usable and reliable solution for moving the second element by the medium pressure is obtained.
- a pressure difference is produced which, at higher outputs of sprayed medium, presses the sleeve down, giving a different spray.
- the pressure difference decreases and the spring used as a counter- element causes the sleeve to rise upwards and a new hole gives a new type of spray.

- the frame part 1 has at least one opening 4.
- the opening 8 in the sec- ond part 7 and the opening 4 in the frame part 1 are arranged to function together so that, when a medium is flowing through them, the nozzle head produces a medium spray, especially a medium mist spray.
- the opening 8 in the second part is thus in the coverage area of the frame part.
- the spray head comprises a valve element 6 which, in the position shown in Fig. 1, is arranged to block the medium flow passage from the inlet 2 to the nozzle formed by the openings 8, 4.
- the second part 7 is arranged inside the frame part 1, in a channel 5, but alternatively it is conceivable that the second part could be arranged outside the frame part, at least in the area where at least some of the nozzle holes of the frame part are arranged.
- a sealing element 12 Arranged in the boring in the frame is a sealing element 12 or the like.
- the sealing element 12 is preferably placed in the boring, pressed between the second part 7 and the part 3 on the inlet side, so that it, together with the valve element 6 movably arranged in the boring in the frame, closes the passage into the channel 9 in the sleeve.
- the valve element 6, i.e. plunger blocks the medium flow passage to the nozzles 8, 4.
- the valve element is locked in the first position by locking means 14, 15.

- the heat-sensitive element 14 may be e.g.
- the means for releasing the valve element may also consist of other types of devices, and they could conceivably function e.g. on the basis of a signal coming from the control system of a fire-fighting system.
- Formed in the valve element 6 is a boring 16, into which the upper end 18 of the ampoule 14 as seen in the figure is arranged to fit. The total length of the ampoule 14 and valve element 6 is fitted to be such that, when the ampoule is in position, the valve element is in a blocking position.
- the medium pressure acting on the valve element 6 end facing towards the inlet 2 causes the valve element 6 to move to a second position (Fig. 2), in which the passage to at least one nozzle 8, 4 is open.
- valve element 6 has at least one opening 17 formed in it, extending from space 9 into boring 16.

- a connection is pro- vided between different openings 4, e.g. by forming a medium channel 23 between the frame 1 and the second part 7, allowing the properties of the spray head to be further extended.
- the medium channel 23 can be effectively created e.g. by forming a groove 23 in the second part 7 (Fig. 13) or in the frame or in both.
- the spraying properties of the spray head can be further extended.
- the sleeve 7 may have a groove formed in the area opposite to the holes bored in the frame, so that at least some of the holes communicate with each other.
- every second hole functions as a nozzle whereas air flows in through the other every second hole when the nozzle functions like an ejector.
- the additional air supply holes make it possible to influence the shape and penetration of the spray discharged. If no supplementary air is used, e.g. a broader and/or softer spray can be produced, whereas by using supplementary air e.g. a narrower and/or sharper spray can be produced.
- Figs. 9 and 10 present yet another embodiment of the invention.
- the second part 7, such as a sleeve part, and the frame 1 can be arranged to be movable relative to each other.

- the sleeve part is in a second position.
- the second part is slidably arranged in the channel 5.
- the second part 7 comprises a groove with a sealing element 22, such as an O-ring or the like, arranged in it.
- the medium pressure and a counter-element for it such as a pre-tensioning element, especially a spring element 20, 21, to assist the motion of the second part, it is possible to achieve a solution for varying the properties of the spray head that is very reliable in operation and advantageous in respect of manu- facturing technology.
- a sleeve element as the second part 7, a very advantageous solution is achieved.
- a throttle element 19 in the sleeve element and using a counter-element 20, 21, a very usable and reliable solution for moving the second part 7 by the medium pressure is obtained.
- a pressure difference is produced which, at higher outputs of sprayed medium, presses the sleeve 7 down (Fig. 10), giving a different spray.
- the pressure difference decreases and the spring 20,21 used as a counter-element causes the sleeve to rise upwards and a new hole 8' gives a new type of spray (Fig. 9).
