In most cases, when in gas cylinder gas reaches a limit, it is simpler to buy gas cylinder, than to try to fill it. However, as usual, people want to save money and to find way how to fill gas cylinder to avoid purchase. Actually, it is not so difficult to make it. Just follow certain instruction and observe security measures.
Instruction
1. So, take normal household gas cylinder with valve (from 5 to 300 liters). Establish it upside down to provide outflow of liquid gas. For this purpose you can make special support or suspend it on rope. Also you can just put it in big old chair. Options the weight, the main thing that the position of cylinder was steady and reliable.
2. Further collect filling system which consists of two hoses, the adapter, the crane and threaded head. Take the crane, hoses, the adapter and cups from the gas equipment better, it is desirable for liquid nitrogen. It will provide durability of system. If you take normal tapping cocks and tubes, then the system will quickly break. Collect everything and strong fix by couplings. Do not use reducer, it will only slow down process of gas station.
3. Screw the adapter on thread of gas cylinder. The crane is required to you for gas supply adjustment. Try not to use valve of cylinder as it quickly enough will fail. Take head on gas thread from the old cutting torch or torch. In case with the cutting torch everything is already ready for fastening to hose, and with torch, perhaps, it is necessary to tinker longer as its diameter insufficiently big for hose. Grip better make metal, do not use plasticity. If to be engaged in it closely and to understand all parts, creation of system for filling of gas will not take you more than one day.
4. Now start directly gas station. Gas flows rather slowly therefore on gas station of one cylinder from three to fifteen minutes, depending on the collected system and volume of cylinder will leave. On any cylinder the gas weight therefore it is possible to control gas station by means of scales is specified. Or approximately: after filling of half of cylinder, pit gas and fill cylinder to top.
5. If to carry out gas station it is accurate also according to all rules, then it is possible to fill cylinder from three to ten times. The main thing, you remember that if on cylinder any external damages have appeared, it is better not to risk and buy new.
