Embodiment Construction

[0017] Refer to attached Figures 1 to 7 Shown, the designed airtight blaster of the present invention adopts special steel material, by blaster support 1, blaster pillar 7, blaster cover 3, blaster through cover 2, blaster end cap 10, primer end cap 5, It consists of a pressure-resistant light-transmitting glass sheet 11, a copper sealing gasket and a pressure relief plug.

[0018] attached by figure 1 , 2 As can be seen, there are two supports, high and low, on the base plate of the blaster support 1, and the high support has two holes up and down, and the low support has a hole. The inner diameter of cylindrical explosive device cover 3 is 35.68mm, and the outer diameter is 80mm. In the middle part of the side of the explosive device cover, a cuboid pillar 7 is welded, and two holes are arranged on the pillar upper and lower. When installing, align the two holes of the pillar 7 with the corresponding holes on the support 1, wherein the lower holes are connected together...

Abstract

The invention provides a manometric bomb for a primer performance test. Two ends of the manometric bomb are of detachable cylinders. The manometric bomb comprises a bomb strut, a bomb support, a bomb sleeve, a bomb through cover, a bomb end cover, a primer end cover, a pressure-resistance transmissible glass sheet, a red copper gasket and the like, wherein primers of various types can be arranged at one end of the bomb, and a transmissible window is arranged at the other end of the bomb, and the temperature when the primer is ignited can be tested by utilizing a colorimetric infrared temperature sensor; a pressure testing hole is formed on the lateral side of the bomb, a pressure sensor can be arranged on the lateral side to measure the output pressure of the primer; and a conical protective cover is designed and arranged in front of the transmissible glass sheet, so that residues of a primer action product can be prevented from jetting on the glass sheet, the glass sheet is protected, and light can reliably transmit. By adopting the manometric bomb, closed environmental space is provided for measuring the pressure and temperature of the primer action product, and the requirement for quantitatively testing primer output energy can be fulfilled.

Description

technical field [0001] The invention belongs to a test device for the ignition performance test of pyrotechnic products, in particular to a closed explosive device for primer performance tests capable of installing various types of primers and meeting the test requirements of piezoresistive pressure sensors and colorimetric infrared temperature sensors at the same time . Background technique [0002] The airtight explosive device is a certain capacity, airtight, pressure-resistant container. It can provide a closed action environment for explosives such as gunpowder and explosives. By measuring the pressure-time curve of the action product in the closed explosive device, the action performance of gunpowder and explosives can be known. In order to measure the output capacity of the primer, a relatively single and traditional measurement method is to test the P-t curve of the pressure of the output gas product of the primer as a function of time. Most of the existing airtig...
