Embodiments of the present invention relate to a kind of gas cylinder bonfire test test macro, as shown in Figure 1, comprise burning source of the gas 1, bonfire test platform 2, safety relief device 3 and remote control computer 4, described burning source of the gas 1 is connected with the input end of electric-controlled ball valve 6 in electric cabinet 5 by pipeline, and the output terminal of described electric-controlled ball valve 6 is connected with bonfire test platform 2 by rapid-acting coupling 7; Described bonfire test platform 2 is provided with for placing the gas cylinder placement mechanism of gas cylinder 8; Described gas cylinder 8 is connected with safety relief device 3; Described remote control computer 4 is connected with the controller of controlling bonfire test platform 2 by wireless network transceiver 9.Described gas cylinder bonfire test test macro also comprises for obtaining the monitor 10 of bonfire test platform image and for the anemoscope 11 of measuring wind, described monitor 10 is all connected with described remote control computer 4 by wireless network transceiver 9 with anemoscope 11.
In this cover pilot system, burn testing table and adopt split-type design, be that each bonfire test platform specification is 0.9m * 0.45m, adopt large gasification case 21 and multi-nozzle formula structure 22, large gasification case 21 provides a gas diffusion chamber for burning, can be by after burning gas source feed, below bonfire test platform, in large gasification case, collect, to guarantee the homogeneity of fire combustion; Multi-nozzle structure 22 adopts 5 * 9 matrix forms to arrange, each injector spacing is 8cm, at correct position, two-way temperature sensor 23 and two portfires are installed simultaneously, thermopair as temperature sensor during burning directly contacts with the bottle of gas cylinder, and for thermopair has designed safeguard structure and Elastic Contact mode, at utmost realized Intensive Design.Wherein, described thermopair is fixed on gasification case by spring, and is arranged between the nozzle of described multi-nozzle structure; The head of the sleeve pipe of described thermopair is also provided with screw-type protection ring.
This project organization has solved following three problems:
The one, split-type design has solved the requirement of the gas cylinder bonfire test of different length, gas cylinder for the long 1m of bottle left and right, the bonfire test platform that can be used alone is tested, for the longer gas cylinder of body, can adopt the mode of a plurality of bonfire test platform parallel connection to test, can effectively meet the rectilinear of plurality of specifications gas cylinder and horizontal bonfire test requirement.
The 2nd, the case multi-nozzle that gasifies greatly design has solved desiredly in standard lights a fire in any given position, and realize the uniform requirement of flame in the short time, can, by regulating flame height to regulate in real time flame intensity, control thus the temperature and pressure of bonfire test simultaneously.
The 3rd, solved the requirement of measuring bottle surface temperature in bonfire test process.Thermopair is conventionally harder, should not be long and be difficult for folding and unfolding, for measuring the temperature of gas cylinder bottle, need to take safeguard procedures to avoid thermopair directly to contact with flame, and adopt casing pipe protection mode that thermopair is directly installed on bonfire test platform, not only solved the trouble of on-the-spot installation temp measuring system, all the other positions that can also avoid thermopair to be exposed in flame occur that temperature is higher than the situation on thermopair top, avoid the distributary phenomenon of thermopair, guaranteed to greatest extent the authenticity of data acquisition.Because the diameter of every gas cylinder differs, therefore can cause the distance of gas cylinder and thermopair all to there are differences.In order to make thermopair be close to all the time bottle, thermopair is connected with spring, because the support of external force, thermopair can perfectly be fitted in tested bottle body bottom all the time.May be because bottle gravity bends thermopair because considering; therefore the head of the sleeve pipe of thermopair has a fixed protection ring in order to protect the head of thermopair; but find in process of the test; the existence of this ring; make thermopair tip have trickle distance with bottle always; what measure is many times the temperature of air, cannot truly reflect bottle problem.By this protection ring is improved, made screw-type protection ring (mode being threaded connection is connected to protection ring on the sleeve pipe of thermopair) into, by screw-type protection ring can regulating ring in the degree that exposes of thermopair, thereby solved this problem.This thermometric mode has been avoided before each flask, all will pasting the trouble of a large amount of temperature strain sheets in the past, when reducing workload, has also improved the accuracy of thermometric.
The source of the gas that burns in this cover system can adopt LPG cylinder group, and it has and is easy to carry, and is convenient to field work, and source is extensively economical, the advantages such as flameholding.This bonfire test platform, except using civil LPG, can also be used the media such as liquefied propylene, rock gas.
When bonfire test amount is larger, test provides source of the gas by two groups of gas cylinder groups of employings, and every group of gas cylinder group is comprised of the liquefied petroleum gas steel cylinder of 4 35.5L, and one not one replaces, and guarantees air feed.
In actual tests, find, this type of steel cylinder generally, after carrying out three, four bonfire tests, can sharply decline because a large amount of air feed cause a bottle interior temperature, and air output is declined.Now, can be in the extremely short time, within about 1～2 minute, change another group gas cylinder group, carry out next round bonfire test.When second group of gas cylinder group tolerance declines, first group of gas cylinder group, because bottle temperature has returned to again normal temperature, can continue again to devote oneself to work.So can in the situation that once transport, can meet 20 left and right gas cylinders are carried out to bonfire test, the gas consumption of bonfire test significantly reduces, and by gas efficiency, also greatly improves.
Bonfire test in the past, all can adopt container truck to transport the effect of car load rock gas at every turn and burn source of the gas, both wastes time and energy, also uneconomical, once there is the accidents such as gas bottle explosion, may bring disaster to rock gas accumulating vehicle, danger is larger, therefore, the gas cylinder group that the present invention the adopts air supply method of rotating, cost is low, safe, convenient operation, than prior art, had very large improving.
In this cover system, safety relief device is the core of design.Find after deliberation, bonfire test device security bleeder main with the factor analysis such as gas cylinder bottle pressure and baked wheaten cake duration, two kinds of comparatively common and serious situations below may occurring in bonfire test process:
(1) if in gas cylinder bonfire test process, burn temperature up to standard, pressure of the inside of a bottle has surpassed correlation standard requirement, and safety feature is not released yet, in order to prevent that gas cylinder from blasting, tackles it and carries out manual pressure release and finish test, is judged to be defective.As, compressed natural gas used as vehicle fuel steel cylinder, steel inner container for containing compressed natural gas hoop winding gas cylinder and steel cylinder for liquefied petroleum gas used for motor.
(2) if in gas cylinder bonfire test process, when bottle, to burn the duration and reach requirement, safety feature is not yet released, and now gas cylinder has met bonfire test requirement, tackles it and carries out manual pressure release and finish test, and it is qualified to be judged to be.As, respirator composite cylinder.
Described safety relief device 3 comprises tensimeter 31, pressure transducer 32 and high-pressure solenoid valve 33, and described high-pressure solenoid valve 33 is connected with the place, cylinder valve gas outlet of described gas cylinder 8 by high-voltage tube, and described high-voltage tube is provided with described tensimeter 31 and pressure transducer 32.Gas cylinder bonfire test platform safety relief device 3 can be connected to cylinder valve gas outlet by high-voltage tube and locate, during test, open cylinder valve, Real-Time Monitoring gas cylinder bottle pressure is controlled high-pressure solenoid valve by computer remote and is opened and closed when bottle hypertonia, realizes bottle medium and releases by high-voltage tube.
When trying out, native system finds, in use, because the encapsulant of the bleed outlet of solenoid valve adopts teflon, its maximum operation (service) temperature is only 200 ℃ of left and right to the high-pressure solenoid valve of being controlled by computer, and in bonfire test process, the gas cylinder temperature in bottle can reach more than 500 ℃.At the test initial stage, from the pipeline to solenoid valve in bottle, only has 1 meter of left and right, cooling system is not designed in centre yet, therefore, high-temperature gas directly impacts and releases the nonmetal seal of solenoid valve, after the releasing of 5 left and right of general experience, its seal is just out of shape deteriorated under the impact of high temperature, cannot realize high pressure sealing again.For warranty test carries out, just must frequently change nonmetal seal, so not only waste time and energy, also there is potential safety hazard.In order to ensure the essential safety of native system, this device is transformed, install manual control high-pressure unloading valve additional in order to relieving pressure, thereby realized binary channels, the dual fail-safe design of safety relief passage.As shown in Figure 2, described high pressure manual unloader 34 can be arranged between described tensimeter 31 and high-pressure solenoid valve 33 safety relief device schematic diagram.
The success or failure whether temperature at fusible alloy place can be measured and whether accurately be related to whole safety relief.If there is no the monitoring of temperature here, cannot understand timely the situation of baked wheaten cake, also cannot adjust timely.At fusible alloy, be wound around soft temperature measuring equipment 35 beyond the Great Wall, this device by switch board directly by thermotonus to controlling on computer.If find that the temperature of fusible alloy does not reach the temperature of regulation all the time, can increase flame by increasing the gaseous tension of the burner of the first side of gas bottle.The increase of flame can make the temperature at fusible alloy place reach in time the requirement of releasing, thereby makes gas cylinder safety relief in time.

During bonfire test system works, bonfire test management control software has carried out a large amount of processing to data.By updating data management and disposal route, improve data-handling capacity and treatment effeciency.Wherein, core data processing section is according to the standard of gas cylinder bonfire test, starts to detect the temperature of each point for measuring temperature, and need to seek the maximum temperature value that appropriate algorithm obtains current measurement point timely and accurately after automatic ignition success.According to most standard requirement, when maximum temperature point being detected and reach 590 ℃, start to enter the data recording stage, until complete test.Detected temperatures maximal value can adopt the fastest bubbling method of processing speed to carry out data sorting.
The placement of gas cylinder is an important problem.Owing to generally can reaching more than 100 kilogram after inflating gas cylinder, so bonfire test platform can adopt stainless steel to make.In order to allow gas cylinder can just in time be placed on the centre of bonfire test platform, can on testing table, weld suspension ring, and on suspension ring, hang up stainless steel chain, and at any time adjusting chain length to regulate the height of bottle.Also can improve bonfire test platform, in bonfire test platform outside, increased a retort stand, this retort stand can adapt to the gas cylinder of maximum model and place, three semi-circular structures on retort stand, have been increased again in order to prevent gas cylinder, thereby can facilitate gas cylinder on brandreth by rotation adjust safety relief device towards, be placed in the optimum position of bonfire test.
Variation for energy measuring wind speed in real time has increased knotmeter in test macro.This knotmeter can reflect on-the-spot wind conditions in real time.Because the variation of wind speed directly can affect the height of flame, thereby affect the temperature of flame and bottle less than the temperature of position, therefore the measurement of wind speed is necessary very much.Described anemoscope is connected with described remote control computer by wireless network transceiver.
In bonfire test requires, require flame can not directly touch gas cylinder valve.At the design initial stage, use a thicker iron plate, and be processed into the mode of semicircle, be stuck in the region of gas cylinder and cylinder valve, but like this in baked wheaten cake process, flame cannot contact cylinder valve at all.Because cylinder liner generally adopts high-strength steel, and cylinder valve is aldary, and fusible alloy is in the widgets of a protrusion of aldary, and different materials causes temperature transmission speed slower.And the time of bonfire test can not be long, overlong time can cause even on fire coming off of winding layer distortion, the safety of Crisis test.
Final inventor has solved the problems referred to above by baffle plate fairly simple but that practicality is very strong.The place, gas outlet of described cylinder valve is also provided with baffle plate, and the outer side edges of described baffle plate is by regulating stent support, and described baffle plate can be by regulating support to carry out lifting; The fusible alloy of described cylinder valve is wound around temperature measuring equipment beyond the Great Wall.This baffle plate is the steel plate that wall thickness is very thin, and support can lifting, can regulate, thus can be according to position and the direction of the angle different adjustment baffle plate of valve.
