Description

Unlike the one-valve gas generators, the proposed gas generator, in order to reduce the gas output to the charging chamber when calcium carbide is supplied to the gas collector with WATER, is equipped with a second automatically operating valve with a float.

The generator can also be safely used when charging it with small-granulation calcium carbide.

The generator shown in the drawing consists of a housing 1, divided by a horizontal partition 2 into two parts - closed and open.

The closed part of the housing serves as a gas collector 5, and the open, upper part is a receiver 4 of water displaced from the gas collector through pipe 5.

Calcium carbide is automatically supplied from the chamber to the gas collector by means of two valves.

One of the valves 6 is associated with a float 7 located in the gas collector and the other valve 8 is connected with the upper float S located in the upper part of the housing 4.

Both valves open and close alternately and automatically, delivering calcium carbide in portions from the loading chamber B to the gas collector.

The hinge cover 10 with a rubber gasket II seals the loading chamber.

The generator has a gas sampling pipe / 2, withdrawn from the gas collector.

The gas generator is charged as follows.

Calcium carbide is loaded into the chamber with the bottom valve closed and the top valve open, which is locked by a bolt 13. Then the lock bolt is unscrewed; the upper valve closes.

Water is poured into the gas collector through pipe 5 to a certain level. At this time, with the help of a float, the bottom valve opens and calcium carbide enters the water reservoir of the gas collector.

With increasing acetylene pressure, water is displaced through tube B to the upper part of the housing.

As soon as the water level in the gas collector is reduced to a normal level, the bottom valve will close,

and the upper valve will open automatically and a new portion of calcium carbide will flow into the volume between the upper and lower valves.

Thus, the calcium carbonate gas collector is loaded automatically and safely, without the acetylene exiting the gas collector back to the charging chamber.

For discharging the gas generator, the upper valve is closed and locked; all the water from the gas collector is discharged through the drain valve 14.

To remove the residue of unused calcium carbide from the loading chamber, the chamber must first be removed from the housing.

The subject of the invention Acetylene generator low

System pressure carbide into water with a housing divided into two parts, in which one part is a gas collector and the other is a water displaced from the gas collector, with a valve for controlling the supply of calcium carbide from the loading chamber to the water collecting container associated with the float in the gas collector, characterized in that, in order to reduce the release of gas into the loading chamber when the carbide is supplied to the gas collector, the loading chamber is equipped with a second valve that is connected to the float located in the receiver be expelled water and closed when the water level is lowered as a result of reducing das. laziness of gas.
