Accompanying drawing explanation
Fig. 1 is the utility model embodiment schematic diagram.
Embodiment
For making those skilled in the art better understand technical scheme of the present invention, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is the utility model embodiment schematic diagram.As can be seen from Figure 1, the portfire 9 that the explosion testing device in the present embodiment has explosive reaction storehouse 10, propagation ducts 14 and is installed in the cavity of explosive reaction storehouse, has sensor 13 in propagation ducts 14.When being full of the mixed gas needing tester and air in explosive reaction storehouse 10, portfire 9 can ignite mixed gas produce blast, the characteristic of detonation propagation under air blast impacts and simulates normal temperature and pressure to propagation ducts 14, sensor 13 detects air-flow and shows.
Sensor 13 in the present embodiment can be one or more in temperature sensor, pressure transducer and flame sensor, the different qualities of test explosion gas.In order to measure in real time and the data of feedback transducer, sensor 13 can be connected with dynamic data automated collection systems, the data of dynamic acquisition, storage sensor 13.Certainly, also free-standing sensor can be set to, by instrument display sensor 13 test data.Portfire 9 in the present embodiment is communicated with external power source 18, controls portfire 9 electric discharge sparking by external switch.
In order to isolate explosive reaction storehouse 10 and propagation ducts 14, when preventing from adding mixed gas in explosive reaction storehouse 10, mixed gas is propagated to propagation ducts 14,5th valve 7 is set between explosive reaction storehouse 10 and propagation ducts 14, opens the 5th valve when needs carry out detonation propagation test.In order to improve control effects and security, the 5th valve 7 can adopt autocontrol valve, realizes valve opening and closing by Long-distance Control.In the present embodiment, the 5th valve 7 is automatic spherical valve; Certainly, also can be other types valve member.
In order to can ready-mixed gas, the present embodiment is provided with tester storage silo 8, tester storage silo 8 has charging aperture 3, the powdery tester needing Exploding test is added by charging aperture 3, and fill to tester storage silo 8 air that adds high pressure, utilize pressure-air that powdery tester is dispersed to Exploding test storehouse 10.In order to realize working alone of various piece, Exploding test storehouse 10 and tester storage silo 8 intermediate connection pipeline are provided with the first valve 2.As the 5th valve 7, first valve 2 also can be autocontrol valve, preferably automatic spherical valve.For realizing the fine dispersion of powdery tester, needing before the test by negative pressure ventilation machine 11, the air in the Exploding test storehouse 10 closed to be discharged, forming certain negative pressure; There is in Exploding test storehouse 10 the second tensimeter 12 measuring negative pressure.Second tensimeter 12 is vacuum table, does not use in blast process, has therefore installed the 6th valve 19 on its pipeline be connected with Exploding test storehouse 10.
For measuring the air pressure in tester storage silo 8, ensure that pressure is in safe range, is provided with the first tensimeter 6, first tensimeter 6 and also can be connected with remote control, realize the long-range reception of real-time testing data in tester storage silo.
For adding pressure-air in tester storage silo 8, high pressure air bottle 5 is provided with in the present embodiment, be connected with tester storage silo 8 by pipeline, and the second valve 17 is installed between high pressure air bottle 5 and tester storage silo 8, enter tester storage silo by controlling the second valve 17 open and close controlling gases at high pressure.In order to ensure the blending ratio of air and tester, simulation actual high-voltage explosive event, high pressure air bottle 5 also directly can be connected with explosive reaction storehouse 10, and arranges the circulation that the 3rd valve 16 controls pressure-air.Second valve 17, the 3rd valve 16 all can be autocontrol valve.Certainly, high pressure air bottle 5 can not be adopted in other embodiments, and directly use air compressor compression generation pressure-air to carry out corresponding charge operation, or directly form mixed gas by fan system winding tester and be filled with explosive reaction storehouse, at this moment the second valve 17, the 3rd valve 16 just can be no longer set.
After Exploding test completes, for discharging the gaseous product in explosive reaction storehouse 10 as early as possible, opening the 3rd valve 16 and passing into gases at high pressure, the air in explosive reaction storehouse just can be discharged from propagation ducts 14 right-side outlet.
In the present embodiment, explosive reaction storehouse 10 and propagation ducts 14 are fixedly mounted on bracing frame 1.Bracing frame 1 is fixed by ground, and the impact that blast produces like this is passed to ground by bracing frame 1.Certainly, bracing frame 1 is not the one integral of the present embodiment, can not arrange yet.
In order to test the various parameters of explosion scene, in explosive reaction storehouse 10, also various sensor can be installed, realize the measurement of several functions, diversiform data.
In order to realize the automatic control of whole system, the present embodiment arranges automatic control system, controls the switch of each valve, the opening and closing of portfire and accepts the sensed data of each sensor, realize the real-time measurement of Long-distance Control and data by slave computer.Each measurement data and operational order are passed to slave computer by master system.
The use procedure of the present embodiment explosion testing device:
1. check sealing, the security of all parts, close each valve;
2. in tester storage silo 8, inject tester by charging aperture 3, this tester is dust-like tester;
3. open negative pressure ventilation machine 11 and the 4th valve 15, being bled by Negative pressure machine makes explosive reaction storehouse 10 form subnormal ambient.Close charging aperture 3, open the second valve 17 and inject pressure-air in tester storage silo 8, now can open the first valve 2 in good time, by pressure-air and suction function, dust-like tester is dispersed to explosive reaction storehouse 10;
4. when explosive reaction storehouse 10 melting concn reaches reasonable value, close the first valve 2, second valve 17, open the 5th valve 7 and test of lighting a fire; Now each sensor 13 can measure the air characteristics in propagation ducts, simulates tunnel detonation propagation characteristic under normal temperature and pressure;
5., after having tested, open the 3rd valve 16, explosion gas is discharged from propagation ducts 14 by pressure-air effect.
Certainly, test process can be recycled, and coordinates reinforced aerating, deflation course, realizes collaborative work, saves time.
In above process 3, the 3rd valve 16 also can be opened in good time, in explosive reaction storehouse, inject pressure-air.If needs tester is inflammable gas, also directly can open the first valve 2, the 3rd valve 16 and inject two kinds of gases in explosive reaction storehouse 10.As adopted dust-like and other class testing things, above test process is also applicable.
Use through actual, the experiment automatized degree of the explosion testing device in the present embodiment is high, and phenomenon is obvious, and success ratio is high, and single time is short, test frequency is high, well tunnel detonation propagation characteristic under simulation normal temperature and pressure.
Above the explosion testing device be suitable in new embodiment is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment; the explanation of above embodiment just understands core concept of the present utility model for helping; when not departing from the utility model principle; also can carry out some improvement and modification to the utility model, these improve and modify and also fall within the scope of protection of the present invention.
