The schematic diagram that Fig. 3 is detachable supersonic speed extinguishing device the second spray orifice of the utility model.
The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
The structural representation that Fig. 1 is the detachable supersonic speed extinguishing device of the utility model, as shown in the figure, detachable supersonic speed extinguishing device of the present utility model specifically comprises: top cover 1, housing 2, porous member 3 and power set 4.
Have through hole 10 on top cover 1, housing 2 is connected with top cover 1; Porous member 3 is contained in housing 2, with top cover 1, socket-connect, the top of porous member 3 has the first spray orifice 31, for the top jet supersonic gas from porous member 3, the sidepiece of porous member 3 has the second spray orifice 32, for the sidepiece from porous member 3, sprays supersonic gas.
Power set 4 are detachable, and through hole 10 is fixed on top cover 1, and are contained in porous member 3.Gas generating agent can be filled in power set 4 inside, and is the power set that electric current causes formula, is used for producing a large amount of gas after receiving starting current.
Like this because the existence of detachable power set 4, requirement for processing, storage and the transportation of supersonic speed extinguishing device just can reduce, because can be processed respectively, power set 4 and miscellaneous part are separately processed and just can greatly be increased security, and can reduce manufacturing cost.Again as shown in Figure 1, detachable supersonic speed extinguishing device of the present utility model also comprises baffle plate 5.Baffle plate 5 sealing-ins are at the opening part of housing 2.
Concrete, an annular nose is arranged below top cover 1, pin thread is arranged on it.And internal thread is arranged at porous member 3 tops, with the internal thread of top cover 1, be connected.Be distributed with some screwed holes on the circumference of top cover 1, be used for connecting trumpet-shaped housing 2.Housing 2 lower ends and baffle plate 5 sealing-ins.And power set 4 are fixed on top cover by the through hole 10 on top cover 1, for example power set 4 and through hole 10 are spirally connected by screw thread, and then power set 4 just have been contained in porous member 3.Porous member 3, housing 2, baffle plate 5 are packaged into an enclosure space, interior shape powder extinguishing agent 6.The inner chamber of porous member is called the first pressure chamber 71; Porous member 3 outer walls, housing 2 and dry powder layer surround the second pressure chamber 72.
The schematic diagram that Fig. 2 is the detachable supersonic speed extinguishing device of the utility model porous member, as shown in the figure, the first spray orifice 31 of porous member 3 is distributed in the bottom of porous member 3, and the axial angle of the first spray orifice 31 axis and porous member 3 is 0 to 90 degree.And the second spray orifice 32 is distributed in the sidepiece of porous member 3.The second pressure chamber 72 shown in Figure 1 again, that the outside of the second spray orifice 32 surrounds towards the upper plane by dry powder 6 and housing 2 and porous member 3 outer walls.The axial angle of the axis of the second spray orifice 32 and porous member 3 is greater than 45 degree, be for example 45 to 135 degree, specifically the axial angle of the axis of the second spray orifice 32 and porous member 3 can be 90 degree, namely the second spray orifice 32 axis and porous member 3 angle radially are 0 degree, and the second such spray orifice 32 can be known as radially spray orifice.
The schematic diagram of detachable supersonic speed extinguishing device the second spray orifice of the utility model as shown in Figure 3 again, the second spray orifice 32 is the side spray hole, and tilts towards a direction, is called the spiral sides spray orifice.
The specific works process is as follows:
When static state, the pressure of the first pressure chamber 71 and the second pressure chamber 72 is zero.After detachable supersonic speed extinguishing device receives starting current, at first detachable power set 4 move, and conflagration discharges a large amount of combustion gas, at the interior rapid formation gases at high pressure product of the first pressure chamber 71.Combustion gas is full of the first pressure chamber 71, and the continuous supercharging of the first pressure chamber 71.When reaching the tension limit of the first pressure chamber film, film is broken through by high pressure draught, and the second spray orifice 32 is opened, and high temperature and high pressure gas highly sprays from the second spray orifice 32, and be full of rapidly the second pressure chamber 72, reach the transient equilibrium of the pressure of the first pressure chamber 71 and the second pressure chamber 72.Now, in the second pressure chamber 72, strong flow perturbation is arranged, the powder extinguishing agent 6 be in contact with it is pulverized and accelerated, the dry powder at this place obtains sufficient atomization, and, in the interior disturbance of housing 2, activity is improved.
In this process, appearance due to the second pressure chamber 72, make the pressure in the first pressure chamber 71 to be discharged in the second pressure chamber 72 by side the second spray orifice 32, surge pressure in the first pressure chamber 71 reduces about 20%--35%, directly reduced the strength of materials requirement to porous member 3, reduce porous member 3 difficulty of processing, reduced production cost and process costs.
Burning is proceeded, and the pressure in the first pressure chamber 71, the second pressure chamber 72 constantly increases, and makes the pressure in whole housing 2 constantly raise.Because powder extinguishing agent 6 is incompressible, so pressure can be delivered to baffle plate 5 places by powder extinguishing agent 6.Until while meeting and exceeding the tension limit of baffle plate 5, baffle plate 5 is broken through, powder extinguishing agent 6 leaves the detachable supersonic speed extinguishing device directive scene of a fire under the effect of high velocity air.Now, the powder extinguishing agent 6 around the second pressure chamber 72 also sprays to the scene of a fire along with powder extinguishing agent 6 one superhigh speeds that activated by the first pressure chamber 71, rather than prior art is the same by free fall type, is dropped or become residual dry powder.Under the effect of high speed inert gas and high speed dry powder jet, the condition of a fire is controlled and is extinguished by moment.
So detachable supersonic speed extinguishing device of the utility model, because there are detachable power set, like this can be so that power set and other devices separately to be processed, processing safety requires to reduce, technological process is simplified, so effective Decrease production cost.And can separately transport, reduce thus the security requirement of transportation, improve Transport Safety, reduce equally cost.And due to the setting of porous member the first spray orifice and the second spray orifice; kinetic energy in the time of can increasing the dry powder preshoot the dry powder that makes prior art fail to be utilized fully are fully used; effective protected area is enlarged, and quenching distance increases, and has improved the fire extinguishing effectiveness of dry powder.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not break away from the spirit and scope of technical solutions of the utility model.
