Abstract
The utility model provides a device for testing the underwater explosion velocity of the explosive, which comprises a pressure device and an explosion cavity, wherein the pressure device comprises a three-way valve respectively communicated with a pressure gauge, an air charging nozzle and an air throttle and a threaded steel pipe, and the air throttle is used for controlling the gas flow enteringthe explosion cavity through the threaded steel pipe; the explosion cavity comprises an upper closed end and a lower closed end for sealing the pipe body; and the upper closed end of the pipe body and the threaded steel pipe are sealed. When the explosive is used, the test sample of the explosive and the water-resistant and pressure-resistant priming tube are placed in the explosion cavity, the explosive is led out of the explosion cavity by the leg wire of the priming tube, then the water is drained to submerge the explosive, then the explosion cavity is filled with air to the air throttle until the pressure reaches that of the underwater depth, and finally the explosive is ignited. The explosion velocity of the explosive is measured by the explosion velocity testing wire led out of theexplosion cavity. The velocity of the underwater explosion which is not detected originally can be measured on land in a simulative manner by the adoption of the device, thereby facilitating the further guidance to the development of the underwater explosion and the explosive.
Description
Technical field
The utility model patent relates to a kind of device of testing explosion velocity of explosive, is specifically related to a kind of device of explosion velocity when testing the explosive underwater blast.
Background technology
The Underwater Engineering blasting technique has been widely used in harbour, waterway dredging reef explosion at present, water-retaining cofferdam or rock bank demolition blasting, chock blasting under the reservoir water, the explosion compacting processing of mud and saturated sandy soil ground etc.Submarine blast design needs the depth of water, flow velocity, data such as morning and evening tides is poor, wave is high, wind speed, underwater topographic map and detailed hydrogeologic data more accurately.In anti-water compressive property, especially the deep water explosion of explosive, must be paid attention in addition.
Explosion velocity is the velocity of propagation of detonation wave (following the shock wave of chemical reaction) in explosive, is one of explosion property of explosive.On land, the explosion velocity of explosive under certain charge density can accurately be measured.But at present, still do not have a kind of simple and easy to do method, show according to relevant document for the test of explosive underwater blast performance: common waterproof explosive, when depth of water 10m, explosion velocity decay 11% and when the depth of water is increased to 30m, explosion velocity will decay 26%.Moreover, also can make explosive density become big because pressure increases, sensitivity to initiation and propagation of explosion sensitivity all can reduce.Some explosion depth of water may be far longer than 30m, so the decay of explosion velocity and explosion velocity is more serious, if do not take measures, not only increases unit consumption, also can cause detonate not exclusively, propagation of explosion interrupts, and has a strong impact on demolition effect.
Because the test for explosive underwater blast performance does not have a kind of simple and easy to do method at present.Therefore the device of development test explosive underwater blast performance has important directive significance to the development of submarine blast and explosive.
Summary of the invention
The purpose of this utility model is by powder charge environment under the Simulated Water, provides a kind of device of the explosion velocity when testing the explosive underwater blast, further to instruct the development of submarine blast and explosive.
The purpose of this utility model be achieved in that this device mainly by pressue device, the blast cavity form, described pressue device comprises tensimeter 1, three-way valve 2, charging connector 3, air throttle 4, threaded steel pipe 12, three valves of three-way valve 2 are communicated with tensimeter 1, charging connector 3, air throttle 4 respectively, and air throttle 4 controls enter the endoceliac gas flow of explosion chamber by threaded steel pipe 12; Described blast cavity comprise on the body seal, body 15, body lower sealing; Seal on the described body and comprise sealing on the body to seal on upper flange plate 13, the body on upper and lower rubber sheet gasket 6, the body and seal lower flange 7, seal upper flange plate 13 and threaded steel pipe 12 on the body and be connected by thread seal; Seal upper and lower rubber sheet gasket 6 on upper and lower ring flange 13 that seals on the body and 7 bodys that reach therebetween by bolt blind flange valve snail hole 5 sealings on body; Described body lower sealing is a plug 11; Seal between lower flange 7 and the body 15 on the body, be tightly connected between body 15 and the plug 11.
The purpose of this utility model further also can realize like this: the body lower sealing is made up of body lower sealing upper flange plate 19, the upper and lower pad 20 of body lower sealing, body lower sealing lower flange 21, the upper and lower ring flange 19 of body lower sealing and 21 and therebetween the upper and lower rubber sheet gasket 20 of body lower sealing by bolt through 18 sealings of body lower sealing ring flange screw, between the lower flange 7 and body 15 that seals on the body, be tightly connected between the upper flange plate 19 of body 15 and body lower sealing.
Described being tightly connected refers to each corresponding coupling part of this device when device is pressurized to the rated pressure of simulated conditions defined, the leakage of gas, liquid can not take place.
Process and principle that this device carries out simulation test are: a certain under water degree of depth is carried out explosion time, these influences can be converted into a pressure value after the influence (mainly being the air pressure and the hydrostatic force sum on hydrostatic surface) of comprehensive various natural conditions to this depth location.Therefore, reach at this device under the condition of seal request, in the cavity of this device body, put into the explosive sample, and discharge water explosive is flooded, after charging into air pressure by this pressure value again in this device, the situation of explosive just should be simulated identical with the situation of same depth under water in this device.During test, use the sealing of suds testing fixture earlier, good as impermeability, then according to GB test explosion velocity of explosive, explosive sample and anti-water resistance to compression detonator are put in the blast cavity, and connect detonator payment to a porter 9 and explosion velocity p-wire 14 (it goes between by after drawing between upper and lower rubber sheet gasket, is connected with the explosion velocity test macro with initiation system respectively), in device, add a certain amount of water, be as the criterion with submergence explosive sample; Then bolt is tightened, carried out leak check once more, if impermeability is good, handle assembly is pressurized to the rated pressure of simulated conditions defined.At this moment, the situation of explosive is just identical with the situation that is in the explosive of respective depth under water in this device.Then air throttle is closed, and unload pressue device, detonate then, at explosion velocity checkout area initiator apparatus to cause bursting, measure explosion velocity numerical value by the explosion velocity proving installation that is connected with the explosion velocity p-wire, this numerical value just should be that same condition is carried out the simulation explosion velocity of explosion time under water.
The beneficial effects of the utility model are, after adopting this device, the explosion velocity that can not carry out during with original explosion under water detects, detect on land with simulated mode, and explosion velocity is one of the leading indicator of the explosion property of explosive, measuring of this explosion velocity helps further instructing the development of submarine blast and explosive.
