Description

Flow guider for nozzle

The present invention relates to a kind of flow guider for nozzle that can spray water for fire extinguishing equably on a large scale.

In the past, for this conducting element, structure was as shown in Figure 6 arranged.

That is, technology in the past is, by means of breach 4a a plurality of water spray plate 5a is bent upwards in the periphery of conducting element body 1a, prolongs in water spray plate 5a simultaneously wherein that any one water spray plate 5a forms supporting slice 6a, again ring bodies 9a is fixed to the upper end.The conducting element that is installed on the fountain head body 10a moves shown in Fig. 6 (C), sprays water for fire extinguishing.

Yet, in above-mentioned technology in the past, owing to be equipped with supporting slice 6a on the distribution channel of water for fire extinguishing, the sprinkling of water for fire extinguishing is subjected to the obstruction of supporting slice 6a, its result, as shown in Figure 7, can produce the so improper part in space that a part can not spray 20, and, because the height setting of shower plate 5a must be than higher, thereby this is to make one of reason of spraying the distance reduction.

Therefore, the present invention makes for solving above-mentioned problem in the past, its objective is water for fire extinguishing can evenly be sprayed in very big scope.

Also be, for addressing the above problem, the device that the present invention taked is, periphery at conducting element body 1 is bent upwards a plurality of water spray plates 5 by means of breach 4, and at least 2 these water spray plates 5 are prolonged and formation supporting slice 6, simultaneously, can be free to slide the extraterrestrial ring bodies 9 that is embedded on the fountain head body 10 in the setting of the upper end of this supporting slice 6, in such flow guider for nozzle, the lower end side outer peripheral face 7 of supporting slice 6 is provided in than the periphery of the outer peripheral face 8 that forms each water spray plate 5 to be justified on the more inboard position of R.

Therefore, the water for fire extinguishing of emitting from the flow export of fountain head body 10, although by impacting on conducting element body 1, be radial water spray the breach 4 between water spray plate 5, but be provided in than on the more inboard position of the periphery circle R of the outer peripheral face 8 that forms water spray plate 5 by the lower end side outer peripheral face 7 of supporting slice 6, thereby discharge, flow into towards the lower end side outer peripheral face 7 of supporting slice 6 with the water for fire extinguishing that the interior phase of water spray plate 5 is impacted, be sprayed onto the outside.Its result although there is supporting slice 6, but still can make water for fire extinguishing spray equably.

Below, an example of related conducting element of the present invention is described with reference to the accompanying drawings.

Fig. 1 has shown an example of conducting element involved in the present invention, (A) is sectional drawing, (B) is ground plan.

Fig. 2 is the part section front elevation that shows same baffle user mode.

Fig. 3 is the part section front elevation that shows the sprinkling state of same baffle.

Fig. 4 is the part cross sectional plane figure that shows the sprinkling state of same baffle.

Fig. 5 is the part section front elevation that shows other form of implementation.

Fig. 6 has shown existing conducting element, (A) is plane, (B) is the general positive map that comprises the part section, (C) is the part section front elevation that shows the sprinkling state.

Fig. 7 is the part cross sectional plane figure that shows existing sprinkling state.

In Fig. 1,1 has shown that the through hole 3 that key 2 is inserted usefulness is located in the tabular conducting element body of central authorities, is bent upwards a plurality of water spray plates 5 by means of breach 4 on its periphery.

The 6th, in water spray plate 5, prolong 3 water spray plates 5 stipulating and the supporting slice that forms, its lower end side outer peripheral face 7 is provided in than the periphery of the outer peripheral face 8 of each water spray plate 5 of the formation of representing with chain-dotted line to be justified on the more inboard position of R and by otch.The 9th, be fixed on the ring body of supporting slice 6 upper ends.

Have, consider the waterdrainage amount of water for fire extinguishing and hydraulic pressure etc., the height H above conducting element body 1 of water spray plate 5 is advisable to be set in 1～2.5mm.

Although this form of implementation is by as above constituting, this conducting element D makes outlet 11 obturations of fountain head body 10 in order to utilize key shown in Figure 22, and its ring body 9 need be arranged to be free to slide extraterrestrial being embedded on the fountain head body 10.

And, 17 is under the situation of the many fountain heads of waterdrainage amount among the figure, the ring-type cowling panel that is embedded into the convex shaped part 18 of key 2 from the outside, because the part of the water for fire extinguishing of being emitted thus can import to the side well by cowling panel 17, even thereby waterdrainage amount increases, also water for fire extinguishing can be sprayed equably.

This fountain head is when breaking out of fire, temperature by sensible heat body 12 rises, but can make solution 13 fusions, fall by the cramping body 14 that makes the below, the chimera 15 that freely stretches is shunk, the cramping body 16 of top is fallen, simultaneously, by the elasticity of helical spring 21, conducting element D is descended as shown in Figure 3, can carry out the sprinkling of water for fire extinguishing.

Therefore, the water for fire extinguishing of being emitted from the outlet 11 of fountain head body 10 and impacting mutually above conducting element body 1 and the key 2 is sprayed onto the outside by means of the breach 4 of conducting element D.

In this case, although the part of water for fire extinguishing is impacted on the inner peripheral surface of supporting slice 6, but because the lower end side outer peripheral face 7 of supporting slice 6 is provided on the more inboard position of the periphery circle R of this outer peripheral face 8 that forms water spray plate 5, thereby as shown in Figure 4, the water for fire extinguishing that impacts with the inner peripheral surface of water spray plate 5 is towards lower end side outer peripheral face 7 side inflows of supporting slice 6, spray towards the outside.Therefore can not produce the space of not carrying out spraying, can water for fire extinguishing be sprayed equably in whole peripheral extent.

And,, thereby can guarantee effective spray radius because the height H of water spray plate 5 can be set extremely lowly.

Have again, under the situation of the many fountain heads of waterdrainage amount, also can adopt the structure that ring-type cowling panel 17 is embedded into the convex shaped part 18 of key 2 from the outside for example shown in Figure 5ly.Thus because the part of the water for fire extinguishing of being emitted imports to the side well by cowling panel 17, even thereby waterdrainage amount increase, also water for fire extinguishing can be sprayed equably.

In addition, key 2 is not restricted to the described embodiments, and also can use structure above being covered by seal 19 made of copper for example shown in Figure 5.

Further, in the above-described embodiments, the supporting slice 6 of conducting element D is made as 3, but concrete number need not investigate, as long as the number of this supporting slice 6 is elected as more than 2 at least, all is feasible.

Moreover conducting element D of the present invention is not limited to the application of the fountain head of the foregoing description, also can be widely used in other structure.

In sum, because the present invention is provided in the lower end side outer peripheral face of supporting slice than on the more inboard position of the periphery circle of the outer peripheral face that forms water spray plate, discharge, flow into towards the lower end side outer peripheral face 7 of supporting slice 6 with the water for fire extinguishing that the inner peripheral surface of shower plate impacts, be sprayed onto the outside, although thereby have such supporting slice 6, but still can obtain special result that water for fire extinguishing is sprayed equably.

And, consider the waterdrainage amount of water for fire extinguishing and hydraulic pressure etc., in the scope of alternative plan of the present invention, because it is very low that the height setting of water spray plate is got, by the reduction that water spray plate can alleviate injection flow rate, the effect of the radius that obtains guaranteeing effectively spraying water.
