Description
Technical field
It the utility model is related to gas cylinder safely detection device technical field, more particularly to a kind of intelligent static evaporation rate test
Instrument.
Background technology
Static evaporation rate refers to, deep cooling container be filled into maximum allowable cryogenic liquid stand 48 it is small when after, 24 it is small when
The percentage of cryogenic liquid quality, is scaled standard ring under the cryogenic liquid quality and container dischargeable capacity of interior natural evaporation loss
(20 DEG C, 1atm) evaporation rate, unit %/d under border.
In the prior art, the measurement of welded insulated gas cylinder static evaporation rate has two methods, and one kind is weight method, another
It is mass flowmenter method.Wherein, weight method is chiefly used in gas cylinder manufacturing unit, for this kind of method inconvenience of gas cylinder periodic inspection
In realization, and low precision, artifical influence factor is more, therefore is rarely employed in gas cylinder periodic inspection work.It is regular in gas cylinder
It is mass flowmenter method to examine the more method used in work.Static evaporation is obtained by mass flowmenter method in the prior art
Rate usually requires to monitor in test：Instantaneous delivery, integrated flow, inlet pressure, inlet temperature, ambient atmosphere pressure, environment temperature
The relevant parameter of degree and ambient humidity, and according to GB/T 18443.5-2010《Vacuum insulation deep freeze refrigeration plant method for testing performance
5 parts：Static evaporation rate measures》Static evaporation rate is calculated middle 8.1.2 and 8.2.1 formula.
According to TSG R0006《Gas cylinder safely technology Supervision Code》Regulation, welded insulated gas cylinder is (containing automobile-used welded insulated
Gas cylinder) it need to examine once within every 3 years.Static evaporation rate measurement be inspection item the most key and important in its checkout procedure it
One, cryogenic liquid is stored in welded insulated gas cylinder liner, thermal insulation material is wound between liner and outer courage and by interlayer vacuum-pumping,
To reach insulation effect.The purpose of static evaporation rate test is on the premise of gas cylinder laminated vacuum is not destroyed, and detects gas cylinder
Vacuum effectiveness.That is, cryogenic liquid (generally liquid nitrogen, automobile-used LNG gas cylinders are liquefied natural gas) will be full of in welded insulated gas cylinder,
Open gas phase blow valve, after pressure of the inside of a bottle stabilization, when 24 is small after in bottle the amount of evaporating number, then judge gas cylinder
Heat-insulating property, finally infer its vacuum effectiveness.
In the prior art when completing test job relevant with static evaporation rate, generally use manual measurement and manually meter

Originally, measurement result easily malfunctions, is related to many technology drawbacks such as instrument and equipment species is various, result of calculation is inaccurate, and one
Having a power failure occurs in denier or other unexpected phenomenons, pre-stage test data are easily lost.Further, static steaming of the prior art
Hair rate detection device is the detection of unit single-station, and an equipment can only examine 1 gas cylinder, and work efficiency is relatively low.Further,
Automobile-used LNG gas cylinders are connected by supporting steelframe fixed structure with vehicle, when making static evaporation rate test according to the prior art, are limited
In existing detection device interface set-up mode, it is necessary to be examined after gas cylinder is pulled down.It is artificial involved by automobile-used LNG gas cylinders dismounting
It is with high costs, and can have the technical risk of damage gas cylinder in disassembly process, how to realize the static steaming free of demolition of automobile-used LNG gas cylinders
Hair rate is examined, and is also those skilled in the art's urgent problem to be solved.Further, because the normal work temperature of mass flowmenter
Degree is 5-45 DEG C, and the accuracy of flowmeter measurement data can be influenced below or above this temperature range, can not also be ensured
The service life of flowmeter, so in the winter time or temperature can not carry out detection work less than 5 DEG C of area, inspection week can be delayed
Phase.Further, since environmental parameter can influence the calculating selection of coefficient, the phase selected in the prior art under the generally use status of criterion
Relation number manually computes, and the result and actually detected state obtained is always there are trickle numerical value difference, so final is quiet
State evaporation rate result also can there are a degree of deviation.
Therefore it provides a kind of intelligence static evaporation rate tester, for overcoming above-mentioned at least one technological deficiency, just becomes
Those skilled in the art's urgent problem to be solved.
