Safety automation of gas-using devices has several degrees of protection in emergency situations:

- when the coolant overheats, it is provided in the presence of a limit temperature sensor 12 (Fig. 1, 2);

- when the flame goes out on the pilot 8 (Fig.1-3);

- in case of traction violation.

The operation of safety automation of gas-using devices is as follows.

In the initial position, gas from the network through the gas supply channel 24 and the filter 23 enters the inlet cavity 22. The valve shutter 15 of the electromagnetic valve 2, due to the force of the spring, covers the bottom of the cavity 17 located between the seat 16 and the electromagnetic valve 2. Before turning on the automatics, you need a handle turn control knob 39 of water temperature 32 clockwise until it stops (position “♦”), while valve 43 of water temperature regulator 32 closes the hole of saddle 44. When the automatics are turned on again, control knob 39 is turned rb until a click is heard when the valve 43 water thermostat 32 closes. It is not recommended to turn the control knob 39 in (position “♦”) at a temperature above 60 degrees.

To ignite the boiler, it is necessary to press the piezo ignition button 14 all the way, while first the valve shutter 15 of the electromagnetic valve 2 will block the hole 17 of the seat 16 from above, while moving the rod 18 of the piezo ignition button 14 will move the valve shutter 15 of the electromagnetic valve 2 to the lowermost position. The hole 17 of the seat 16 will open from the bottom and the gas from the outlet cavity 22 through the hole of the seat 20 and the channel 21 in the solenoid valve body 2 and the ignition tube 13 will begin to flow to the igniter 8. Then ignition 8 should be ignited. When igniting the ignition 8, the thermocouple 9 will start to produce .D.S. After warming it up (in the range of 10-60 s.) E.D.S. will be enough to hold the solenoid valve 2. The piezo ignition button 14 is released and the valve shutter 15 rises with it, opening the hole 17 of the seat 16 from above, while the gas flows into the cavities 19 and 46. Turning the control knob 39 of the water temperature controller 32 counterclockwise, set the required temperature of the coolant or air in the heated room, while the rod 36 rises, releasing the plate 42, the valve 43 opens, gas begins to flow to the main burner of the burner pipes 10 and the ignition is ignited nickname 8. When water or air in a heated room is heated to the required temperature, the thermoballon 34 is heated with it. The thermostatic fluid enclosed in it expands and flows through the capillary tube 35 into the bellows 37. The bellows 37 expands and moves down the spring rod 36, which interacts with the plate 42. When a certain force is reached, the plate 42 instantly (by clicking) moves the valve 43 of the water temperature controller 32, which closes the opening of the seat 44. Actuation of the valve 43 leads to a complete cessation Started main burner of burner tubes Yu.Posle bulb 34 cools the bellows 37 is compressed - the valve 43 opens.

The described process is periodically repeated, thus maintaining the set value of the water temperature (50 ÷ 90 ° C) in the boiler or the air temperature in the heated room for convectors (15 ÷ 30 ° C), for bath stoves (70 ÷ 120 ° C).

The gas pressure in the manifold of the gas burner device (GGU) is maintained by the gas pressure regulator 3. The gas pressure regulator is adjusted with the adjusting screw 25. To turn off the gas pressure regulator, it is necessary to turn the adjusting screw 25 clockwise until it stops.

The operation of the safety automatics of gas-using devices in emergency mode occurs when the flame of the igniter 8 is extinguished, due to cooling of the thermocouple 9, or in case of traction violation. In the latter case, the draft sensor 5, heating up from the products of combustion, breaks the eclectic circuit 11 between the thermocouple 9 and the electromagnetic valve 2. At the same time, the valve shutter 15 of the electromagnetic valve 2 shuts off the gas supply to the main burner of the burner pipes 10 and the igniter 8.

When the coolant overheats, the temperature limit sensor 12 turns off the gas supply.

An open circuit 11 also occurs when you press the button "STOP" 53 emergency shutdown, if there is a thermocouple 9.

The design of the control unit 1 of the automation provides for the adjustment of the power of the igniter 8 using a screw 51 located on the front side of the unit under the cap 52.
