Description
Technical field
The present invention relates to analysis field tests and in particular to a kind of for screw plug seal rigid container gas on-the-spot test
Device.
Background technology
The low-boiling point liquid group such as isopropyl nitrate, oxirane is usually contained in the warhead charge of some armament systems
Point, the increase with equipment active time and transport, in storage process environmental factorss impact it may occur however that warhead is close
The envelope phenomenon such as rubber burn into is aging, leading to evaporates produces gas and is diffused in the cavity of whole equipment, causes weapon bullet
Medicine lost efficacy and jeopardized storehouse and personal security.Therefore, to armament systems inside, potential gas leakage detects, for weapon
The life appraisal of equipment, safe storage and accident analysis are significant.
In producing assembling process, the enclosure interior of such weapon would generally fill the noble gases of certain pressure to ensure
Safety, enclosure interior passing hole channel is communicated with the outside and is sealed with screw plug.For such rigid seal container internal gas
Collection and measurement, the gas sampling bag of commercialization is not had suitable interface to complete to dock with container, cannot be extracted by needle tubing yet
Mode sampled, in the case of not destroying its structure, at screw plug, sampled measurements are a kind of most viable methods.If straight
Take out screw plug test, internal gas and outside air occur rapidly gas exchange, and measured result cannot truly reflect in equipment
The original concentration of portion's gas, therefore, sampling and test process need to carry out under conditions of strict seal.Currently for such
In sampling apparatuses using the rigid container of screw plug sealing, can be connected simultaneously at screw plug with the sleeve of rubber tube and ad hoc structure
Sealing, opens screw plug using the screw rod in sleeve, and the gas in container is imported in sampler bag by the gas circuit hole of sleeve inner.
But, this device is strict to the size of sleeve and requirement on machining accuracy, and each covering device can only specifically be used for size coupling
Sampling Interface;Meanwhile, this device utilizes sampler bag to collect gas, not connecting test instrument, and sample also needs through once turning
Move past journey it is impossible to carry out on-the-spot test.
Content of the invention
Seal the gas on-site testing device of rigid container provided by the present invention for screw plug by sampling storehouse, band, gas
Body canal, screw rod, pressure gauge, effusion meter etc. forms;Sampling storehouse is flexible material, and internal preset screw rod simultaneously introduces gas conduit;
Sampling storehouse fully wrapped around screw plug sealing rigid container end, fills lute and is fixed with band at gap;Gas conduit is altogether
Have three, including suction catheters, air induction conduit and test conduit, each conduit is provided with valve, suction catheters connect pressure gauge and
Vacuum pump, air induction conduit is connected with argon by effusion meter, and test conduit connects gas tester.First with vacuum pump during test
Go out to sample air in storehouse by suction catheters platoon, subsequently volume is carried out by the argon that air induction conduit is quantitatively passed through certain volume
Calibration, connects gas tester reading data by testing conduit after opening screw plug.
Advantage of the invention is that:
(1) test process completes in confined conditions, can avoid, with outside air, gas exchange impact test knot occurs
The accuracy of fruit.
(2) carry out full environmental sealing it is adaptable to the screw plug of different specification size seals rigid container using flexible sampling storehouse
Internal gas are tested.
(3) sampling is carried out with test process simultaneously, and achievable screw plug seals the on-the-spot test of rigid container internal gas.
Brief description
The present invention is described in detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the schematic diagram of apparatus of the present invention.In figure 1. samples storehouse, 2. band, and 3. screw plug sealing rigid container, 4. takes out
Airway, 5. air induction conduit, 6. test conduit, 7. screw plug, 8. screw rod, 9. pressure gauge, 10. vacuum pump, 11. effusion meters, 12. argons
Gas, 13. gas testers, 14. evacuating valves, 15. air intake valves, 16. test valves.
Specific embodiment
As shown in figure 1, the structural representation for apparatus of the present invention.By flexible sampling storehouse 1 fully wrapped around screw plug sealing rigidity
Container 3 end, built-in screw rod 8 simultaneously introduces three gas conduits, respectively suction catheters 4, air induction conduit 5 and test conduit 6.Its
In, suction catheters 4 connect pressure gauge 9 and vacuum pump 10, and air induction conduit 5 connects argon 12 by effusion meter 11, and test conduit 6 is even
Connect gas tester 13, every conduit is all with controlled valve.Sampling storehouse 1 and screw plug seal at the gap between rigid container 3
Filling lute, and be tamping with band 2.Open vacuum pump 10 and evacuating valve 14, be completely exhausted out sampling the air in storehouse, this
When sampling warehouse overstock be condensed to zero.Close evacuating valve 14 and vacuum pump 10, stand five minutes, check the sealing of system;If
Pressure gauge reading is unchanged, is considered as air tight, can carry out next step operation.Open air intake valve 15, be passed through the argon of certain volume
Gas 12.Close air intake valve 15, using screw rod 8 open screw plug seal rigid container 3 end screw plug 7, standing 15 minutes so that
Gas seals from screw plug and is fully diffused in rigid container 3 in sampling storehouse 1 and reaches balance.Open test valve 16, by gas
Body tester 13 measures.
