Embodiment Construction

[0030] like Figure 1 to Figure 4 As shown, the present invention provides a collector and sealing device for explosive aging release gas, including a collector device 3 and a sealing device, the collector device includes a glass gas sampling tube 31, and the upper end of the glass gas sampling tube is connected with a The two branch ports are respectively the first branch port 32 and the second branch port 33. The first branch port 32 is a sampling branch port, which has a large diameter and is straight up and down. The plug-in connection is convenient for adding powder samples and small test pieces with a diameter of less than 10mm, and at the same time prevents the flame from entering the glass gas sampling tube to ignite the explosive when the opening is sealed with an open flame; the second branch 33 is a vacuum branch , the vacuum branch is a step-variable diameter type, which is vertically connected with the glass gas collection pipe at right angles, and there is a capi...

Abstract

The invention discloses an explosive aging outgassing acquisition and melting and sealing device. The device comprises an acquisition device and a melting and sealing device, wherein the acquisition device comprises a glass gas acquisition pipe, two branches are connected with a part of an upper part of the glass gas acquisition pipe and are respectively a first branch and a second branch, the first branch is connected with the glass gas acquisition pipe in an inclination and insertion way, the second branch is vertically connected with the glass gas acquisition pipe, the melting and sealing device comprises a support and a glass melting and sealing protection device, the glass melting and sealing protection device is fixedly arranged on an upper surface of the support and is of a two-segment sleeve structure, a lower-segment sleeve is fixedly connected with the upper surface of the support, an upper-segment sleeve is a replaceable sleeve, and the inner diameter of the upper-segment sleeve is matched with the external diameter of the glass gas acquisition pipe. By the device, the problem of long-term sealing performance of an existing glass gas acquisition container is effectivelysolved, meanwhile, the device is safe to operate, and subsequent gas taking and analysis operation is facilitated.

Description

technical field [0001] The invention relates to explosive aging evaluation and detection technology, in particular to an explosive aging release gas collector and a melting sealing device. Background technique [0002] Explosives are thermodynamically in a metastable state, and under the action and influence of environmental stress (such as temperature, radiation or the synergy of the two), they will undergo slow chemical changes and release gases, and at the same time, secondary reactions with gases will occur , to form more complex gas products, so the outgassing components and content are considered to be important characteristics of explosive aging. Accurate qualitative and quantitative detection of outgassing components of explosives under different environmental conditions is very important for mastering the aging law and analysis of explosives. Its aging mechanism, and then predict its storage and service life is of great significance. [0003] In order to know the o...
