Device for initiating blasting charge of explosive
专利摘要:
Improvements for a low energy fuse inserted into a blasting cap wherein the fuse is in the form of a hose and the blasting cap comprises a tubular cover containing an explosive and optionally, a delay detonator. The tubular cover receives the hose so that the end of the hose is in facing relation with the detonator or explosive. A moisture-proof barrier is disposed between the fuse and the explosive or detonator and comprises a diffusion-tight rigid tube inserted into the hose and having a flange extending outside the hose in abutment therewith. A diffusion-tight film or foil covers the flange to seal the interior of the tube and thereby the hose from the interior of the cover. The film or foil is ruptured by the blast wave upon detonation of the hose. 公开号:SU845770A3 申请号:SU792748402 申请日:1979-04-06 公开日:1981-07-07 发明作者:Лундборг Ханс;Кристенсен Лейф;Нюквист Стиг 申请人:Нитро Нобель Аб (Фирма); IPC主号:
专利说明:
The invention relates to blasting, in particular for means of initiation. A device is known for initiating an explosion of an explosive charge (explosive), containing a detonator capsule made of metal or plastic and made open from one end and with a blank bottom from the other end of a cylindrical sleeve, inside which there are charges of initiating explosives at a blank bottom, and in the open end is fastened with a loaded explosive flexible tubular sleeve made of plastic fl]. The known device has the disadvantage of moisture penetrating through the flexible sleeve and its core to the initiating explosive charges, which reduces their initiating effect. The purpose of the invention is to increase the reliability of initiating an explosive charge explosion in conditions of high humidity. This is achieved by the fact that in a device for initiating an explosion of an explosive charge, comprising a detonator capsule made of metal or plastic and made open to another CPPO at one end and with a blank bottom c; the end face with a cylindrical sleeve inside which the charges of the initiating explosive are placed at a blank bottom, the equipped end is secured with the equipped explosive flexible tubular sleeve made of pl mass, a part of the flexible sleeve replicated in the sleeve is fitted with a raceproof barrier in the form of a raceproof rigid tube with a gastric closure facing the charges initiators: but there is a paradise of flax on the BBB flange, to which a moisture-proof wound from a material permeable to an explosive wave is attached, and at the same time! We used such material) foil or film, and the outer K] of the flange of the rigid tube, facing the charges of the initiating explosives, vyps. beveled or rounded, and vg; impermeable membrane bent; Rigid flange rigid tube. In FIG. 1 shows a device in partial longitudinal section! in FIG. 2 - node dock moisture impermeable barrier with capsule detonator; in FIG. 3 - node 1 of FIG. 2. A device for initiating an explosion of a charge of explosives contains plastmotVTO m; ΙβΜ3 th flexible tubular sleeve 1 with explosive 2 inside. A flexible tubular sleeve 1 is inserted inside the open end of the metal or plastic case 3 of the capsule-mount and mounted in it, for example, by rolling the sealing casing 4. Then, charges 3 of the initiating explosives are located in the body 3 to the dead bottom (in the drawing of the show). At the end of the flexible tubular sleeve, a moisture-proof barrier is installed in the form of a moisture-proof rigid tube 5 made of metal or plastic, having a flange 6 on which a moisture-proof membrane 7 is attached, either of foil or of a film permeable to a blast wave. E The front edge of the flange 6 is or rounded or beveled for convenient bending of the membrane on it 7. A flexible sleeve can absorb moisture, which then enters the explosive charge inside it, and after that it can get onto the charges of the initiating explosives and reduce their reliability and initiating effect. A moisture-proof barrier (tube and membrane) prevents the penetration of moisture to the charges of initiating explosives. In addition, the membrane of the moisture-proof barrier prevents the loss of a loose lying explosive.

Claims (4) [1] The invention relates to blasting, in particular, to the means of initiation. A device for initiating an explosion of an explosive charge (cb), containing a detonator cap made of metal or plastic and made open at one end and with a deaf bottom from the other end of a cylindrical sleeve, in which at the bottom of the deaf bottom are located the charges initiating BB, and in the open end, a flexible tubular plastic sleeve 1 is attached to the wound BB. The known device has the disadvantage of moisture penetrating through the flexible hose and its core to the initiating charge of the explosives, which reduces their initiating action. The purpose of the invention is to increase the reliability of the initiation of an explosion of an explosive charge under conditions of increased wet conditions. This is achieved by the fact that, in a device for initiating an explosion, an explosive charge containing a detonator cap made of metal or plastic and made open at one end and a deaf bottom at the end of the cylindrical sleeve inside which the deaf bottom is charged The open end is fixed with an explosive hose. A flexible tubular hose of pl mass, in a part of the flexible sleeve replicated in the sleeve, a permeable barrier in the form of a permeable rigid tube facing the charges is established by initiating the BB with a flange to which ich attached waterproofness wound from a blast wave permeable material, while in Single ve such material used foil or film, and on) uzhny flange to a rigid tube, facing the initiating explosive charge give, vyps chamfered or rounded, and BJ; impermeable membrane bent flange rigid tube. FIG. 1 shows a device with a partial longitudinal section in FIG. 2 shows a docking assembly for a moisture impermeable barrier with a cap detonator in FIG. 3 - the node of FIG. 2. A device for initiating a BA explosive charge contains a plastic flexible tubular sleeve 1 with an explosive 2 inside. The flexible tubular sleeve 1 is wound inside the open end of the metal or plastic body 3 of the detonator capsule: the torus and is fixed in it, for example, by sealing the sealing case 4. Next, in case 3, the charges of initiating explosives are located (shown on the drawing). At the end of a flexible tubular arm, a moisture-tight barrier is installed in the form of a moisture-tight rigid tube 5 made of metal or plastic, having a flange b, on which a membrane 7 or a foil or film is attached, which is waterproof or permeable to an explosive wave. The front edge of the flange 6 is either rounded or beveled for conveniently bending the membrane 7 on it. The flexible sleeve can absorb moisture, which then enters the explosive charge inside it, and after that it can fall onto the charges of initiating explosives and reduce most of their reliability and initiating action. A moisture-proof barrier (tube and membrane) prevents moisture from penetrating to the charges of initiating explosives. In addition, the membrane of the moisture-proof barrier prevents leakage of loosely packed explosives. Formula 1: A device for initiating an explosion of an explosive charge, containing a detonator cap made of metal or plastic and made open from one end and with a deaf bottom from the other end of a cylindrical sleeve inside which has detonating initiating explosives near the deaf bottom substances, and in the open end, a flexible tubular sleeve made of plastic is fixed with an explosive, characterized in that, in order to increase the reliability of initiating an explosion of an explosive charge In conditions of high humidity, a waterproof barrier in the form of a waterproof rigid tube with a flange facing the charges of the initiators of explosive substances, to which a moisture-permeable membrane permeable to a blast wave is sealed, is installed in a part of the flexible sleeve fixed in the sleeve. [2] 2. The device according to claim 1, 1, 1 and 2, in that it uses a foil or film as a permeable blast material. [3] 3. The device according to Claim 1, characterized in that in it the outer edge of the flange of the rigid tube, facing the charge of the charging initiating explosives, is either made obliquely or rounded. [4] 4. Device on PP. 1, 2 and 3, distinguished by the fact that it is moisture-proof membrane bent around the flange of a rigid tube. .
