How to pump air into a can
A can of compressed air is used to blow dust and dirt out of hard-to-reach places with a directed flow. It is used to clean various boards, keyboards, fans, etc. Such a can is a necessary thing, but its cost is clearly overpriced. In this regard, it is more cost-effective to make an adapter to pump compressed air into empty gas cylinders with a collet connection for mini burners.
A gas cartridge for burners can withstand a pressure of 17-20 atmospheres, so it can be used for pumping air without any fear, after first making sure that there is no gas in it. Such a cylinder is equipped with a valve that allows gas or air to pass in both directions, but only while being pressed. The collet mount of the torch can compress it into the correct position, so the adapter for refueling must be made from it.
The burner tube is sawn in half.The peculiarity of this homemade product is that the assembled adapter can be used for pumping air, and then, if necessary, reassembled into a fully functioning burner.
To do this, you need to take the valve from the chamber and connect it to the tube from half of the burner with a collet mount.
These parts are soldered. In order for the tin to hold securely, you must first clean the valve from any remaining stuck rubber.
Then take the valve cap and drill a hole through the top. Next, it is inserted with the side with the antennae into the tube of the upper half of the burner and also soldered.
Now, if you need to use the sawn burner for its intended purpose, its halves are twisted. Naturally, when docking, the spool is removed from the valve.
When it is necessary to pump air into an empty cylinder for purging, only half with a collet is installed on it. In this case, a spool valve is screwed into the valve. After this, a compressor or hand pump is connected to the adapter, and air is pumped in. Before this, you need to open the valve on the burner itself so that air can freely flow into the can.
To be on the safe side, it is better not to pump the pressure to more than 10 atmospheres, that is, half of what the cylinder can withstand. If you use a hand pump or a small car compressor when pumping, you will hardly be able to get more than 7-8 atm.
After filling with air, a deodorant sprayer with an inserted tube is installed on the cylinder. It is possible to use an ear stick as this. In this form, the cylinder can be used for cleaning.Since it is pumped with atmospheric air and not with special gas, it is only enough to clean one computer or keyboard. In the future, if necessary, the cylinder can be re-inflated as many times as necessary until its valve begins to leak air from wear.
Materials:
- gas burner with a collet connection without electric ignition;
- empty gas cartridge;
- chamber valve with a metal cap;
- deodorant sprayer.
