Specific embodiment：
Spray parameters test device of the present invention is described further with specific embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, spray parameters test device of the present invention includes left box body 1, raising middle flask
Body 2 and right case 3, left box body 1 and right case 3 use hard transparent material, such as acrylic board, safety glass, as case
Wall, using the purpose of hard material not still in order to be used for the forming shape of equipment itself, and can also preferably bear weight
And impulsive force during injection.Transparent effect can be the spraying situation for more intuitively observing box house.Middle casing 2 is left
End is tightly connected by the first adpting flange 15 and bolt 18 with the right-hand member of left box body 1, and the right-hand member of middle casing 2 passes through the second adpting flange
16 and bolt 18 be tightly connected with the left end of right case 3.It is provided with test device front and is with the left end center line starting point of left box body
Mark origin (mark starting point), the length scales 4 being marked on the basis of casing center line and spraying diffusion angle scale 6,
Length scales 5 and spraying diffusion angle scale 6 run through left box body 1, middle casing 2 and right case 3.In other words, scale long
The mark starting point of chi 4 and spraying diffusion angle scale 6 is arranged on the high order end of the front center line of left box body 1, length scales 4
Trend with casing front center line overlap, and spray diffusion angle scale 6 with casing front center line position be 0 °.Length scales
5 scale values are a measurement unit with every 100mm, and the scale value of spraying diffusion angle scale 6 is with every 5 ° for a measurement unit.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, the left end of left box body 1 is provided with injection entrance 4, left box body 1 and right case
3 bottom is equipped with dry powder recovery port 7, sewage draining exit 9 and universal wheel 14.The effect of sewage draining exit 9 is after both having can be used for spurting
The recovery of dry powder, it is also possible to dust and other impurities cleaning during for regular maintenance.It is dry that the setting of universal wheel 14 is easy for the present invention
The movement and transport of powder spray parameters test device.The top of left box body 1 and right case 3 is equipped with pressure relief opening 8, during test, lets out
Pressure mouth 8 connects external dry powder returnable by external flexible pipe 17.In test process, when the pressure in casing is excessive,
Casing is susceptible to bursting accident, and the setting of pressure relief opening 8 will not occur accident when can ensure that injection test because of explosion.Such as Fig. 1,
Shown in Fig. 2 and Fig. 3, spray gun fixed support 10 is provided with the injection entrance 4 of the left end of left box body 1, on spray gun fixed support 10
It is connected with spray gun fixing hoop 11.
As shown in figures 1 to 6, middle casing 2 is extension type transparent cabinet, and the telescopic transparent cabinet is mutually flat by five
Capable support keel 12 and the transparent thin-film material 13 of connection support keel 12 are constituted, and the every bottom of support keel 12 is connected with
Two universal wheels 14.The length of middle casing 2 can freely stretch as needed.Because transparent thin-film material is softer, therefore this
A little support keels mutually can be overlapped arbitrarily, so as to allow the length of casing during middle casing 2 changes by stretching according to actual needs
Degree.
In the present invention, effective jet length refers to spray the highest distance position that the inner core conical surface can be arrived, maximum jet length
From referring to spray the highest distance position that male cone (strobilus masculinus) can be ejected into, these are all the term of spraying, therefore do not repeat herein.Angle of flare
Degree, effective jet length, maximum these three data of jet length are testers straight by the scale on the casing of left, center, right
Connect range estimation gained.
Specifically used process of the invention is：
1st, carry out box body combinations installation first, will left box body 1, middle casing 2 and right case 3 pass through the first adpting flange 15
It is sequentially connected with bolt 18 with the second adpting flange 16, and checks whether sewage draining exit 9 and the plug of dry powder recovery port 7 are tightened, together
When two pressure relief openings 8 are connected in dry powder returnable by external flexible pipe 17 and fixed；
2nd, casing leak detection is then carried out, the nitrogen after will depressurizing stretches into injection entrance 4, is continually fed into, and checks each connection
The air-tightness of point；
3 and then the flexible experiment of middle casing is carried out, i.e., after device integrated connection, stretch left box body 1 and the right side to both sides respectively
Casing 3 arrives longest distance, then pushes away and be reduced to beeline, and whether casing 2 can normally stretch in experiment；
4th, test operation is then carried out, spray gun is placed on spray gun fixed support 10 and is carried out with spray gun fixing hoop 11
Fixed, spout stretches into injection entrance 4 and adjusts spray gun to horizontal level, confirms two external flexible pipes 17 of pressure relief opening 8
It is connected respectively in external returnable；
5th, following pretrigger spraying, the maximum jet length of observation spraying (can suitably adjust test box extremely to close if needed
Suitable length), and check again for whether first flange 15, second flange 16, sewage draining exit 9 and dry powder recovery port 7 have leakage；
6th, spraying is again started up, by the diffusion angle of spray diffusion angle scale 6 and the measurement spraying of length scales 5, is had
The data such as effect jet length, maximum jet length are simultaneously recorded, in test process, can be by two pressure relief openings 8 to casing pressure release；
7th, after the completion of last test, stripping device, you can the dry powder for staying will be collected in casing and reclaimed by recovery port.
Spray parameters test device of the present invention is not only applicable to the spray parameters test in powder extinguishing system, Er Qietong
Spray parameters test of the sample suitable for Water spray fire extinguishing system and water spray extinguishing system, except that, gone out in Water spray
In spray parameters test in fiery system and water spray extinguishing system, the function of dry powder recovery port 7 and the function one of sewage draining exit 9
Sample, dust and other impurities cleaning during for regular maintenance, but water not recycling, and the water smoke or water droplet that pressure relief opening 8 overflows
Not recycling.In addition, during the spray parameters in Water spray fire extinguishing system and water spray extinguishing system are tested, injection entrance 4 is just
It is the entrance of water.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to model of the invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art are to technical side of the invention
The various improvement that case is made, all should fall into the protection domain of claims of the present invention determination.
