Description

Control device for the fuel supply for gas-heated steam or hot water boilers The subject of the invention is a control device for the fuel supply in gas-fired steam or hot water boilers. It is already known in such devices, the temperature or the pressure in the boiler, as well as the outside and inside temperature have an effect on thermostats to let who make the regulation. The well-known institutions were used let the thermostats or control thermometers act on special devices, which, in turn, first open the air valve for the supply, the combustion air hired. There was no direct fuel control.

The invention. now guarantees particularly economical fuel consumption and the most precise regulation by the fact that the fuel supply to the heating burner regulating valves, influenced by the thermostats, one behind the other in the fuel line leading to the burner is installed.

The drawing shows an exemplary embodiment of the inventive concept schematic.

In the drawing, the wall of a "room is indicated by a, in a boiler b for the production of warm water or steam for any Purposes, e.g. B. for heating purposes is set up; c is. the gas burner for heating of the boiler and d the gas supply pipe. In the gas supply pipe is now initially in a known manner any designed gas control valve e switched on, which from the steam pressure in the boiler b or from the temperature of the generated in the boiler warm water is dependent and the gas supply line d shuts off if the desired Temperature or the desired pressure has been reached.

According to the invention, a gas control valve is now also f in the line d installed, which through a line g with a thermostat h in Connection. The latter is located outside the room, i.e. in the outside air. It is therefore influenced by the temperature of the outside air and it always blocks depending on the external temperature, the gas supply line decreases more or less. Finally is yet another gas control valve i is provided, which through a line .h with a thermostat is in communication. The latter is in the room that is heated shall be. It is influenced by the temperature of this room and is depending on more or less shut off the gas supply line from the heat prevailing in it.

You can either use the different gas regulating devices side by side arrange them and combine them in a common housing, but they can also be arranged independently Attach from each other at different points on the gas supply line; also is that The design of the specified control valves as well as the design of the thermostats are completely arbitrary.

In certain cases it will be sufficient if the gas supply from the outside temperature or only by the inside temperature. It is sufficient then the additional arrangement of a thermostat.

In the case of other means, e.g. B. by electricity, liquid fuel o. The like., Heated steam or hot water generators, the invention can accordingly be used, with the respective heating means in place of the gas regulating valves must arrange appropriate control devices.
