Welded insulated gas cylinder of the present utility model is furnished with guard circle at an upper portion thereof; seat ring is furnished with in bottom; the pipeline valve system that guard circle mainly protects gas cylinder top to be equipped with; use as hanging piece when carrying simultaneously; foundation ring mainly keeps the steady erectility of gas cylinder; foundation ring built with rubber shock-absorbing circle, to reduce the vibrations to inner bag when gas cylinder transport pallet is put.
Welded insulated gas cylinder of the present utility model should be noted following situation in use:
1.1 gas cylinders clean by oxygen unit requirement before using
With the matching used spare part of the welded insulated gas cylinder of splendid attire liquid oxygen and equipment, have to pass through the cleaning process with oxygen compatibility, determine the qualified operating mode that the component contacted with liquid oxygen or oxygen must have " cleaning by oxygen unit requirement ", otherwise likely will draw super burn to burn, cause casualties accident.
1.2 keep ventilating, away from flammable and explosive substance
When using welded insulated gas cylinder, must carry out under air flows sound ventilation environment.For when filling or use oxygen, " oxygen-enriched environment " (the CGA's environment of definition oxygen content more than 23% is oxygen-enriched environment) can be produced when ambient oxygen concentration is too high, if when now there is combustible material in environment, violent or blast may be caused.Deposit at oxygen (liquid oxygen), operate, the place such as use should isolate with organic substance, inflammable and explosive substances and place, particularly oil, kerosene, gasoline, fat oil, tar, timber, cotton, paint etc. and the waste containing oil or fat oil thereof.Forbid depositing at oxygen, place smoking, the igniting such as operation or produce electrostatic.

Welded insulated gas cylinder of the present utility model uses:
Welded insulated gas cylinder, gas phase can export liquid gas, provide the gas of the different pressures in predetermined range, flow for user, also liquid phase can export liquid gas, provide the different pressures in predetermined range, the liquid of flow for user.
1.1 gases use
Gas is provided to be the most basic purposes of welded insulated gas cylinder to user, rapid and main points are as follows by jia bombardier:
1, use at welded insulated gas cylinder gas (or on connecting pipeline) on the joint of valve (gas valve) that suitable decompressor is installed, between gas equipment and reduction valve, connect suitable use air pipe;
2, pressure charging valve and gas use valve is opened;
3, by observing gas cylinder upward pressure table, when inner bag working pressure meets or exceeds the setting value of economic adjustment valve, economic adjustment valve is opened, the gas source now provided in year is the saturated vapour of the gas-phase space at inner bag top, gas enters built-in vaporizer by economic adjustment valve, become gentle gas after absorbing heat, use valve to flow to supply air line, to user's air feed by gas.The working pressure of inner bag can be made like this to be declined;
When inner bag working pressure is reduced to the setting value lower than economic adjustment valve, economic adjustment valve cuts out, and the source of air feed is the liquid bottom inner bag.Liquid medium enters liquid in-out pipe by the pressure in water heater container top gas phase space, enter built-in vaporizer again, gentle gas is become after absorbing heat, by the outside air feed of supply air line, because little liquid can become the gas of significant volume, therefore such inner liner pressure only has and declines slightly.
When working pressure continues to decline, during setting pressure lower than boost pressure regulation valve, boost pressure regulation valve will be opened, now liquid is by the pressure piping bottom inner bag, gas is become after absorbing heat, entered the top of inner bag by boost pressure regulation valve, thus the pressure in inner bag top gas phase space is raised, otherwise boost pressure regulation valve cuts out.
4, adjust decompressor and use atmospheric pressure to suitable.
5, complete with gas, close all valves.
1.2 liquid use
Rapid and main points are as follows by jia bombardier:
When welded insulated gas cylinder does feed flow use, with the achievable rate of liquid, depending on the gaseous pressure of inner bag and the temperature of liquid, for security consideration, advising, when using liquid, pressure of the inside of a bottle to be reduced as far as possible.
1, connecting pipeline is to the liquid in-out valve of welded insulated gas cylinder
2, pipe being filled be connected to and filled container, if open hood type container, filling pipeline end, the device that prevents liquid splash should be installed.
3, open and filled the liquid-filling valve of container and atmospheric valve.
4, the liquid in-out valve of welded insulated gas cylinder is opened, and coutroi velocity
5, fill complete, close successively and filled the valve of container, welded insulated gas cylinder liquid in-out valve, opens the atmospheric valve filled on pipeline, with the emptying liquids and gases filled in pipeline.
6, close the valve of all welded insulated gas cylinders, remove and fill pipeline.
The welded insulated gas cylinder that the utility model provides, clean health, to filled gas without any pollution, can reuse and fill, safe and reliable, easy to use, charging ratio is high.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
