Description
Technical field
This utility model relates to a kind of device testing explosion velocity of explosive, is specifically related to a kind of device testing explosive explosion time explosion velocity at low temperatures.
Background technology
Along with the extensive use in the extremely frigid zones engineering explosion technology such as Xinjiang, Inner Mongol, frozen soil layer explosion can be frequently encountered by, explosion is opened ice etc. when temperature is lower than-30 DEG C explosion situation.But when being by blast working, explosive resistance to low temperature is poor, easily miss-fires under low temperature environment, it is necessary to take the measure of rising again normally to use, bring great inconvenience to construction.Therefore the resistance to low temperature of explosive, it is necessary to paid attention to.
Explosion velocity of explosive refers to detonation wave spread speed in explosive, is one of explosion properties.Under normal circumstances, explosive explosion velocity under certain degree of packing has multiple accurate measuring method.But at present for explosive explosion velocity test at low temperatures, but without method simply and easily.
In view of there is no one method simply and easily for the test of explosive explosion velocity at low temperatures at present.Therefore the device of explosion velocity under test explosive low temperature is developed the development of blast working under low temperature and explosive is significant.
Utility model content
The purpose of this utility model patent is in that by simulating low temperature environment, it is provided that a kind of test the device of explosion velocity of explosive under low temperature, to instruct the development of explosion and explosive under low temperature further.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of test the device of explosion velocity of explosive under low temperature, it is characterized in that, including blast cavity, the freezing attemperator being located in explosion chamber body and test system, blast cavity has body, the lower end of described body is provided with the lower sealing of closed tube lower end, and the upper end of body is provided with upper sealing upper flange and the lower sealing lower flange of closed tube upper end；Freezing attemperator includes the saline solution nilas and the heat-preservation cotton that set gradually from outside to inside；There is the groove of explosive sample at heat-preservation cotton center；Test system includes initiator and the detonation velocity meter of being located at described body side, and the bottom of explosive sample is provided with detonator, and detonator is connected with initiator by detonator payment to a porter；Being provided with two probes in the middle part of explosive sample, probe is connected with detonation velocity meter by explosion velocity test lead.
Preferably, being provided with wire casing between upper sealing upper flange and lower sealing lower flange, detonator payment to a porter is through described wire casing, and explosion velocity test lead is also through described wire casing.
Preferably, also including the thermometer for measuring explosive specimen temperature, the lower end of described thermometer is placed on inside explosive sample through upper sealing upper flange.
This device is simulated the process of experiment and principle is: when carrying out Exploding test at a certain temperature, first explosive and this device is together put freezing at such a temperature and reaches to want seeking time.During test, first lower sealing is connected with antistatic body；Then saline solution nilas and heat-preservation cotton and explosive sample are assembled, with fully wrapped around live explosive sample be as the criterion, and connect detonator payment to a porter and explosion velocity test lead；Again the explosive sample after wrapping is put into cavity, two flanges of upper sealing by bolt compact siro spinning technology；Now thermometer is inserted observation explosive temperature in sample, thus explosive sample is maintained under cryogenic, and the true temperature that can record during test in explosive.Then at test site initiator apparatus to cause bursting, drawing the explosion velocity under explosive low temperature by the detonation velocity meter being connected with explosion velocity test lead, this numerical value should be just the simulation explosion velocity carrying out explosion time at the same temperature.
This utility model has the advantages that
After adopting this device, under normal temperature experimental condition, realize the test of explosion velocity of explosive under low temperature by simulating the mode of low temperature environment, and one of explosion velocity explosion property index that to be explosive important, this device is conducive to instructing further the development of explosion and explosive under low temperature.
