Description

A kind of device of reusable testing underwater brisance of explosive
Technical field
The utility model relates to a kind of device of testing underwater brisance of explosive, is specifically related to a kind of device of reusable testing underwater brisance of explosive.
Background technology
The ability of pulverizing and destroy the object that is in contact with it during explosive charge is called the brisance of explosive, and on land, the brisance of explosive under certain charge density can accurately be measured.But test for explosive underwater blast performance, because submarine blast is to carry out in the environment of water is arranged, the key element that not only influences explosion is more, objective condition such as anti-water compressive property, lithology structural environment and maritime meteorology situation as pore-forming technique, charge process, explosive, all submarine blast is constituted influence, so its blasting technique is more more complex than land explosion.And, to the result after the submarine blast, all be difficult to measure such as parameters such as brisance, explosion velocities.Owing to above reason, limited this subject development of submarine blast, make submarine blast lag behind the development of production practices theoretically.
In view of this, the applicant applied for Chinese patent " a kind of device of testing underwater brisance of explosive " (number of patent application: 200910094374.3) on June 19th, 2009, blast analogue is under water carried out to the land, and on land the parameter after its blast is tested.This device mainly is made up of pressue device, blast cavity, and pressue device comprises three-way valve, the threaded steel pipe that its three passages are connected with tensimeter, charging connector, air throttle respectively, the cavity that explodes comprise on the body seal, body, body lower sealing; Seal on this body and comprise sealing on the body to seal on upper and lower rubber sheet gasket, the body on upper flange plate, the body and seal lower flange; Seal upper flange plate on the body and be connected by thread seal, seal upper and lower rubber sheet gasket on upper and lower ring flange that seals on the body and the body therebetween by bolt blind flange valve snail hole sealing on body with threaded steel pipe; This body lower sealing is made up of body lower sealing upper flange plate, body lower sealing rubber sheet gasket, body lower sealing lower flange, the upper and lower ring flange of body lower sealing and therebetween body lower sealing rubber sheet gasket by bolt through the sealing of body lower sealing ring flange screw, between the lower flange and body that seals on the body, be tightly connected between the upper flange plate of body and body lower sealing.During the test explosive brisance, explosive sample, steel disc, lead block and anti-water resistance to compression detonator are put in the blast cavity, and the detonator payment to a porter is connected with initiation system, in device, add a certain amount of water, be as the criterion with submergence explosive sample; Then bolt is tightened, carried out leak check, 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,, measure the length of blast front and back lead block, just can obtain the simulation brisance that same condition is under water carried out explosion time at blast checkout area initiator apparatus to cause bursting.Said apparatus can be simulated the underwater blast of explosive preferably, thereby can measure its brisance parameter through being facts have proved.But its weak point is, because this device each several part is in fully and compresses sealing state, after explosive charge, threaded steel pipe part in the lower flange that seals on the body of device, the body, the upper flange plate of body lower sealing even the pressue device also is damaged, thereby can only disposablely use, and can not reuse, cause the waste of material.
Summary of the invention
The purpose of this utility model is to provide a kind of and both can have simulated the underwater blast of explosive, thereby can measure its brisance parameter, the device of the testing underwater brisance of explosive that can be repeatedly used again.
The purpose of this utility model is achieved in that employed device is the improvement of the device in the above-mentioned background technology, this device comprises pressue device and blast cavity, pressue device comprises tensimeter 1, three-way valve 2, air throttle 3, steel pipe 4, three passages of three-way valve 2 are communicated with air supply hose, tensimeter 1, air throttle 3 respectively, and air throttle 3 controls enter the endoceliac gas flow of explosion chamber by steel pipe 4; In addition, this device also comprises connecting screw rod 7, operating platform 19; Described blast cavity comprises upper flange plate 6, upper flange plate rubber sheet gasket 8, body 10, lower flange rubber sheet gasket 17, lower flange 18, and corresponding screw is arranged on upper and lower ring flange 6 and 18, also has the mounting hole of the binding post 5 of detonator on upper flange plate 6; Described binding post 5 is the binding post of conductor for appearance insulation inside; Its annexation is: be installed in the mounting hole of upper flange plate 6 to the insulation of binding post 5 appearances, its lower end is connected with detonator payment to a porter 9, and its upper end can connect detonator igniter; Steel pipe 4 and upper flange plate 6 seal weldings; The upper and lower end of body 10 is connected with upper flange plate rubber sheet gasket 8, upper flange plate 6 and lower flange rubber sheet gasket 17, lower flange 18 respectively successively, with the be connected screw of connecting screw rod 7 by upper flange plate 6 and lower flange 18 correspondences upper flange plate 6, lower flange 18 is compressed with upper flange plate rubber sheet gasket 8, lower flange rubber sheet gasket 17 and body 10 sealings then.
The process that this device carries out the testing underwater brisance of explosive simulation test is: during test, the blast cavity places on the operating platform 19, use the sealing of suds testing fixture earlier, good as impermeability, reach the requirement of national regulation, then operate according to GB, explosive sample 14, steel disc 15, lead block 16 and waterproof resistance to compression detonator 13 are put in the blast cavity, and connect detonator payment to a porter 9, and in device, add a certain amount of water 12, be as the criterion with submergence explosive sample 14; Then bolt 7 is tightened, carried out leak check once more, if impermeability is good, then open air throttle 3, charge into pressure gas 11 in the blast cavity, handle assembly is pressurized to the rated pressure of simulated conditions defined.Then air throttle 3 is closed, and unload pressue device, the initiator apparatus to cause bursting is connected with binding post 5, ignite, measure the length of the front and back lead block that explodes, just can obtain the simulation brisance that same condition is under water carried out explosion time at the blast checkout area.
The principle that this device can repeat the testing underwater brisance of explosive simulation test is: when explosive charge, with lead block that explosive directly contacts be subjected to exploding damage in, last rubber sheet gasket 8, following rubber sheet gasket 17 are also by explosive damage, thereby producing air gap between upper flange plate 6 and the body 10 and between lower flange 18 and the body 10, the gas with enormous impact power that blast produces releases from air gap, thereby has reduced impact and damage to the device other parts.
The invention has the beneficial effects as follows, adopt this device after because the damage that is subjected to of this device is less, therefore, after only needing to change rubber sheet gasket, this device is still reusable in identical test, the unlikely waste that causes material.
