Embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model spray parameters proving installation is described further:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the utility model spray parameters proving installation comprises left box body 1, middle casing 2 and right case 3, left box body 1 and right case 3 all use hard transparent material, as acrylic board, tempered glass etc., as tank wall, adopt the object of hard material not still in order to the forming shape for equipment self, and impulsive force when can bear weight better and spray.Transparent effect is the spraying situation can observing box house more intuitively.Middle casing 2 left end is tightly connected with left box body 1 right-hand member by the first joint flange 15 and bolt 18, and middle casing 2 right-hand member is tightly connected with right case 3 left end by the second joint flange 16 and bolt 18.Be provided with in proving installation front with the left end center line starting point of left box body as mark initial point (mark starting point), with casing center line for benchmark carries out the length scales 4 that marks and spraying diffusion angle scale 6, length scales 5 and spraying diffusion angle scale 6 all run through left box body 1, middle casing 2 and right case 3.In other words, the mark starting point of length scales 4 and spraying diffusion angle scale 6 is arranged on the high order end of left box body 1 front center line, the trend of length scales 4 and casing front center line overlap, and diffusion angle scale 6 of spraying is 0 ° with casing front center line position.Length scales 5 scale value is a measurement unit with every 100mm, and spraying diffusion angle scale 6 scale value is a measurement unit with every 5 °.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, left box body 1 left end is provided with and sprays entrance 4, and the bottom of left box body 1 and right case 3 is equipped with dry powder recovery port 7, sewage draining exit 9 and universal wheel 14.The effect of sewage draining exit 9 is the recovery that both may be used for spurting rear dry powder, also may be used for dust and other impurities cleaning during daily servicing.The setting of universal wheel 14 is movement and the transport of being convenient to the utility model dry powder parameter test device.The top of left box body 1 and right case 3 is equipped with pressure relief opening 8, and during test, pressure relief opening 8 connects external dry powder returnable by external flexible pipe 17.In test process, when the pressure in casing is excessive, easily there is bursting accident in casing, and the setting of pressure relief opening 8 can be guaranteed can not meet accident because of explosion when spraying test.As shown in Figure 1, Figure 2 and Figure 3, injection entrance 4 place of left box body 1 left end is provided with spray gun fixed support 10, spray gun fixed support 10 is connected with spray gun fixing hoop 11.
As shown in figures 1 to 6, middle casing 2 is extension type transparent cabinet, this telescopic transparent cabinet is made up of the transparent thin-film material 13 of five support keels be parallel to each other 12 and connection support keel 12, is connected with two universal wheels 14 bottom every root support keel 12.The length of middle casing 2 as required can free-extension.Because transparent thin-film material is softer, therefore these support keels can be mutually arbitrarily overlapping, thus the length of casing in allowing middle casing 2 change by stretching according to actual needs.
In the utility model, effective jet length refers to the highest distance position spraying the inner core conical surface and can get at, and maximum jet length refers to the highest distance position spraying male cone (strobilus masculinus) and can be ejected into, and these are all the terms of spraying, therefore do not repeat at this.Diffusion angle, effectively jet length, these three data of maximum jet length are all that tester directly estimates gained by the scale on the casing of left, center, right.
Concrete use procedure of the present utility model is:
1, first box body combinations installation is carried out, be connected successively with the second joint flange 16 bolt 18 by the first joint flange 15 by left box body 1, middle casing 2 and right case 3, and check whether the plug of sewage draining exit 9 and dry powder recovery port 7 is tightened, two pressure relief openings 8 are connected in dry powder returnable also fixing by external flexible pipe 17 simultaneously;
2, then carry out casing leak detection, stretch into by post-decompression nitrogen and spray entrance 4, continue to pass into, check the impermeability of each tie point;
3, then carry out the flexible test of middle casing, namely after device integrated connection, respectively to both sides stretching left box body 1 and right case 3 to longest distance, then push away and be reduced to bee-line, in test, whether casing 2 can normally stretch;
4, then test operation is carried out, spray gun is placed on spray gun fixed support 10 and is also fixed with spray gun fixing hoop 11, spout stretches into and sprays entrance 4 and regulate spray gun to horizontal level, confirms that two pressure relief openings 8 are connected respectively in external returnable with external flexible pipe 17;
5, next pretrigger spraying, observes the maximum jet length of spraying (if needed can suitably adjust test box to appropriate length), and again checks whether the first flange 15, second flange 16, sewage draining exit 9 and dry powder recovery port 7 have leakage;
6, again start spraying, measured diffusion angle, the effectively data such as jet length, maximum jet length record of spraying by spraying diffusion angle scale 6 and length scales 5, in test process, by the 8 pairs of casing pressure releases of two pressure relief openings;
7, after last test completes, stripping device, can be reclaimed collecting in casing the dry powder stayed by recovery port.
The utility model spray parameters proving installation is not only applicable to the spray parameters test in powder extinguishing system, and the spray parameters test be applicable to too in Water spray fire extinguishing system and water spray fire extinguish system, difference is, in spray parameters test in Water spray fire extinguishing system and water spray fire extinguish system, the function of dry powder recovery port 7 is the same with the function of sewage draining exit 9, for dust and other impurities cleaning during daily servicing, but water no longer reclaims, and pressure relief opening 8 overflow water smoke or water droplet also no longer reclaim.In addition, in the spray parameters test in Water spray fire extinguishing system and water spray fire extinguish system, the entrance that entrance 4 is exactly water is sprayed.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various improvement that those of ordinary skill in the art make the technical solution of the utility model, all should fall in protection domain that the utility model claims determine.
