Description
The utility model relates to and a kind ofly anti-fires fighting apparatus especially a kind of sprinkler tip.
China's utility application discloses a kind of AS 95231097.X number, this sprinkler tip mainly is made up of framework, vitreum and splash box three parts, be provided with screw thread silk head in the framework bottom, on the silk head, have water inlet, be provided with the cover for seat of the inside and outside sealing gasket of band at framework delivery port place, vitreum lower end and cover for seat are joined, and the vitreum upper end links to each other with the framework upper end, and splash box is positioned at the framework top.When stating sprinkler tip in the use, it can be installed on the building abutment wall, and its water inlet and tap water pipeline are joined.When fire occurring, specially designed vitreum is subjected to high-temperature baking and breaks, and before by the corresponding unlatching of the delivery port of vitreum shutoff, running water sprayed by delivery port, impacted in splash box and spilt down towards periphery, reached the purpose of self-extinguishing.In above-mentioned existing product, the shape of splash box will produce decisive influence to the spray effect of current.But existing product does not carry out preferably the structure of splash box.The sprinkling area coverage of present widely used 10mm, 15mm sprinkler tip is usually in B～12 square metre, and its area coverage is less, has caused the system pipe network complexity, thus the defective of existing.
The purpose of this utility model is that the shape of splash box is carried out preferably, and a kind of bigger sidewall sprinkler head of coverage rate that sprays is provided.
Sprinkler tip of the present utility model has support body, vitreum and splash box, bottom at support body is provided with pipe joint, be provided with vitreum seat with the delivery port shutoff at the delivery port of pipe joint, be provided with the vitreum holding screw on the top of support body, splash box is fixed in the upper end of support body.In the utility model, above-mentioned splash box is " L " shape seat shape splash box for being made of base plate and backboard especially, join under end and the backboard after the base plate of this splash box, angle between base plate and the backboard is 97 °, this base plate links to each other with the upper end of described support body, offers pod apertures at base plate near the central part of backboard.Use checking through reality, the pod apertures that adopts above-mentioned specially designed splash box can allow current offer from base plate is sprayed on backboard, and by the sputter of backboard current is spilt out fully, thereby reaches preferable fire extinguishing effect.In addition, with regard to sprinkler tip of the present utility model, also can be on the basis of above-mentioned basic splash box structure, do further preferred to the transverse shape of the pod apertures offered on the base plate and the profile of base plate and backboard.
Sprinkler tip of the present utility model is compared with aforementioned existing product, because the structure of splash box has been carried out preferably, thereby help increasing the sprinkling area coverage.Through evidence, adopt the cloth water area of the sprinkler tip of the utility model structure can reach 32.8 square metres, its extinguishing ability improves greatly, and the corresponding quantity that is provided with that reduces sprinkler tip in the fire extinguishing system is simplified pipe network structure.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the structural representation of sprinkler tip among the embodiment.
Fig. 2 is the structural representation of splash box.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is the side view of Fig. 2.
Shown in Fig. 1～4, sprinkler tip in the present embodiment has support body 1, vitreum 2 and splash box 3, be provided with pipe joint 4 in the bottom of support body 1, be provided with vitreum seat 7 at the delivery port 6 of pipe joint 4 with this delivery port shutoff, be provided with vitreum holding screw 8 on the top of support body 1, splash box 3 is fixed in the upper end of support body 1.In the present embodiment, above-mentioned splash box is " L " shape seat shape splash box for being made of base plate 9 and backboard 10 especially, join under end and the backboard 10 after the base plate 9 of this splash box, angle α between base plate 9 and the backboard 10 is 97 °, this base plate 9 links to each other with the upper end of described support body 1, offers pod apertures 11 at base plate 9 near the central part of backboards 10.During sprinkler tip in using present embodiment, can utilize pipe joint 4 and running water pipe to join.When fire alarm occurring, vitreum 2 is subjected to high temperature and breaks, vitreum seat 7 comes off under the effect of hydraulic pressure automatically, running water enters from the water inlet 5 of pipe joint 4, again from delivery port 6 ejections, pod apertures 11 on base plate and clashing into to backboard 10 by splashing down after the bounce-back of backboard 10, realizes automatic fire-extinguishing function downwards.In the present embodiment, the cross section of the pod apertures 11 offered near the central part of backboard of above-mentioned base plate at splash box is " recessed " shape.Simultaneously, have protruding forwards left and right protruding 12,13, constitute water conservancy diversion diffusion breach 14 between this left and right projection in the front center of the base plate 9 of splash box.The diffusion part 15 that has from the bottom to top, protrudes from inside to outside at the backboard middle part of splash box.Has the left and right water conservancy diversion tailgate 16,17 that extends under the base plate 9 in the bottom of splash box backboard 10.Test shows that the above-mentioned design of splash box base plate and backboard all helps the sprinkling of current, can further increase the cloth water area of sprinkler tip.In addition, also between vitreum seat 7 and pipe joint delivery port 6, be provided with metal mold elastic seal ring 18 in the present embodiment, this metal mold elastic seal ring both can assist 7 pairs of pipe joint delivery ports of vitreum seat 6 to carry out shutoff when no fire alarm, help vitreum seat 7 when fire alarm occurring, to come off again, guarantee the normal use of sprinkler tip from pipe joint delivery port 6.
