Description

The apparatus for producing acetylene known up to the present time has the disadvantage that water, necessary for the formation of gas, goes very slowly to the carbide, so that with an increased consumption of gas, the gas in the gasometer is depleted before fresh water reaches the carbide and through the formation of gas reimburse the amount of gas consumed. Due to this, a temporary excess of oxygen is obtained in the welding flame, which acts in an oxidizing manner on the welding ground. In the opposite case, when gas consumption is stopped, water comes down from the carbide at the same, relatively low speed, so that for a certain period of time after gas consumption is suspended, some gas formation occurs. If the gas meters of such devices are not large enough, their gas overflows, due to the subsequent gas formation, which is accompanied by the release of gas from under the bottom.

edge of the gas meter out and may cause an explosion.

The present invention aims to remedy this disadvantage by quickly adjusting the pressure under the bell and quickly ceasing gas generation in the carbide chamber.

A device for regulating gas generation in pressure-type acetylene generators consists of a floating gas tank, which is used to regulate the flow of water into the carbide chamber, which is connected to the gasholder by a tube with two processes; One of the processes is provided with a knee immersed in the liquid under the bell to release gas under pressure, and the other with a valve connected to the bell, due to which there is a rapid increase in pressure under the bell and the water is quickly expelled from the carbide chamber.

In FIG. 1-3 depict vertical cuts of the proposed fixture in three design options.

The letter a denotes a water tank, and a gas meter bell, an e-front tank connecting: tank a, d-cleaner, e-water constipation and f-vessel with back pressure, in the middle of which is installed a 1c pipe for gas release. While the top opening of the pipe k in the previously known gas separators never closes tightly, so that the subsequent evolution of gas occurs through the same opening, in the proposed fixture tightly closed with a special mechanical valve V from above, and then the gas formed via a special tube S (Fig. 1).

Formed in a carbide tube, the pelvis passes through pipe h and lifts the bell. When the bell is slightly raised, the counterweight on the valve spindle v and set in motion by the bell, the counterweight closes the opening of pipe I, and the gas formed thereafter, the passage through pipe s meets resistance to a solid column S-, what is the value of water in the carbide the chamber is displaced, so that the formation of gas cannot take place. As soon as the tap V is opened by the action of the bell, the carbide will be brought into contact with water at the same moment, and water will be immediately displaced from the carbide chamber if gas consumption is less; if the gas enters the bell in a quantity slightly larger than consumed, the bell is raised and; tap V is closed.

In the fixture depicted in FIG. 2, the pipes / pipes are not located side by side, but one in another. In this case, instead of a tap, the closure of the opening of the li pipe is achieved by breaking a ball or valve v made of rubber or other sealing material mounted on the pipe s, which is actuated by the arms H, hinged on the pipe If. This lever, in turn, is driven by a ring D reinforced inside the bell b. As soon as the carbide in the carbide chamber d comes into contact with water, the resulting gas passes through the pipeline and the counterpressure vessel f, as well as through the open hole of the pipe k into the bell b: From the moment more gas enters the bell whereby the bell goes out through the tube g, the bell rises, and the tube st lowers the valve and the upper opening closes. When the bell is lowered again, so that the ring L actuates the lever and, and the pipe s with the valve rises, water comes in contact with the carbide, and gas is formed again until the bell rises and closes the opening of the pipe K and until water is again forced out of the carbide chamber. At the end of gas consumption, the latter is forced to pass through the opening JB in the pipe k, then through the annular space between the pipe / s and pipe 5, and then through the water into the bell. FIG. 3 shows a device different from that shown in FIG. 1 and 2 in that the locking device crane v is located outside the bell. The gas supply pipe p and the discharge pipe g are connected by means of a connecting pipe k, so that the gas leaving the carbide chamber through pipe h does not pass through the bell, but directly through the pipeline Jc to the water lock E. The crane v is equipped with a counterbalanced lever which is activated by means of a rod G, mounted on the bell in such a way that when the latter is lowered, the valve opens, and when raised, it is closed by the action of the counterweight.

The gas leaving pipe A is supplied in the lower position of the bell through the pipes and and i to the water lock or to the place of gas consumption. Upon termination of consumption, the gas is forced, when it enters the bell, to pass through the pipe S, mounted on the vessel f, and the gas must overcome
