State of the art

Known atmospheric gas burner containing two gas regulators connected in series, each of which consists of a control and regulation unit, flame and traction sensors, two valves, an ignition sensor with a bimetallic plate connected to the burner, and a furnace, three temperature regulators, each block control and regulation consists of a start button to the mains gas, a membrane with a rigid center, a valve with a seat, a supmembrane cavity, a membrane and a two-position shutter, a drainage nozzle and a pressure source nozzle, a throttle ator channel (see. The atmospheric gas burner. RGU-M1. Instruction Manual. CA 2.574.023.RE "Plant Starorusspribor" 175200, Staraya Russa, Novgorod region., street. Mineral, 24).

The disadvantage of this burner is the design complexity, low reliability.

Known nozzle assembly of the burner, comprising a housing with a guide plate mounted outside it and bent end bent at a predetermined angle relative to its plane towards the flow, while the plate from the side opposite the bent end is provided with a pivot axis perpendicular to the longitudinal axis of the body and its end bent at an angle 10-15 ° (see.with. SU No. 989244, IPC F23D 13/26).

The disadvantage of this nozzle node of the burner is the design complexity, low reliability.

The closest in technical essence and the achieved positive effect and accepted by the authors for the prototype is an atmospheric gas burner containing a gas regulator, consisting of a control unit connected to a temperature sensor using a control channel, a control unit connected to flame sensors, a draft control channel, with this it is equipped with a second gas regulator, consisting of a control unit connected to temperature and outdoor air sensors, a control unit, while the second gas the heater is installed with the possibility of parallel connection of the cavities of the control units and the outdoor temperature sensor by connecting a second gas regulator to the control unit, and the percentage of gas supply to the burner by both regulators is set by taps (see US Pat. No. 2196939, IPC F23N, F23D 14/60 )

The disadvantage of this burner is the design complexity, the lack of a constant connection with the ambient temperature.

Disclosure of invention

The objective of the invention is the development of a gas power controller with a simplified design, increased reliability and the ability to automatically control the power of burner devices at low temperatures.

The technical result, which can be obtained using the present invention, is to simplify the design, increase reliability and automatically control the power of the burner devices at low temperatures.

The technical result is achieved using a gas regulator, comprising a valve body with inlet and outlet pipes of an external gas pipeline, a manometric system with a sensing element, an adapter, an adjustment spring, a rod connected by a lock washer to one end of the adjustment spring, a threaded sleeve, the regulator being equipped with a rotary valve with a window for minimum gas supply at a positive outside temperature, and a manometric system with a sensitive element through an adapter is installed it is connected to the threaded part of the valve body, while the rotary valve is made to interact with the control disk of the manometric system mounted on the second end of the stem and separated from the threaded sleeve by a remote sleeve that provides automatically controlled gas supply at low outdoor temperatures and full gas supply in the event of a malfunction manometric system.

Brief Description of the Drawings

The drawing shows a gas regulator, a General view.

The implementation of the invention

The gas regulator consists of valve body 1, adapter 2, gauge system 3, while in the valve body 1 there is an inlet pipe 4 and an outlet pipe 5 of the external gas pipe located behind the insulated wall 6 of the boiler (not shown), inside the valve body 1 on the hinge 7 is equipped with a rotary valve 8 with an emphasis 9 and a window 10 of the first stage of minimum gas supply at a positive outdoor temperature, and the gauge system 3 consists of a sensing element 11, a housing 12, a rod 13, adjustable spring 14, the latter is fixed at one end to the stem 13 by means of a lock washer 15, and the second rests against the threaded sleeve 16, which changes the initial force of the spring 14, at the end of the rod 13 are a control disk 17 lift and a remote sleeve 18, while the rotary valve 8 made with the possibility of interaction with the control disk 17 of the gauge system 3, mounted on the second end of the rod 13 and separated from the threaded sleeve 16 by a remote sleeve 18, which provides automatically controlled gas supply at low temperatures ax of external air and full gas supply in case of malfunction of the gauge system.

The gas regulator operates as follows.

With a positive outside temperature, the gauge system 3 through the stem 13, the control disk 17 with the stop 9 supports the rotary valve 8 in the closed state, gas from the external gas pipeline through the inlet pipe 4 enters the valve body 1 and through the annular gap between the rotary valve 8 and window 10 of this valve 8 in the amount of 30-40% of the boiler capacity (the volume of gas of the first stage is determined structurally) enters through the outlet pipe 5 into the gas burner device of the boiler, with a decrease in the outdoor temperature, about the volume of fluid in the gauge system 3 between the housing 12 and the sensing element 11 is reduced, the adjustment spring 14 lifts the rod 13 with the control disk 17 through the lock washer 15, under gas pressure, the rotary valve 8 is rotated around the axis of the hinge 7, constantly resting against the control 9 the disk 17 is opened, and the increased volume of gas continues to flow into the burner, and when the outdoor temperature reaches - 10 -: - 12 ° C, the gas power regulator provides 100% gas supply. Thus, the main part of the gas, 60-70%, is automatically regulated by the gauge system 3 from frost on the street, with an increase in the outdoor temperature to positive values, the volume of liquid in the gauge system 3 increases, and through the lock washer 15, compressing the adjustment spring 14, the rod 13 with the control disk 17 goes down and transfers the force through the stop 9 to the rotary valve 8, which, turning around the hinge 7, goes down, leaving window 10 in the rotary valve 8 and the annular gap between the turn for gas supply th valve 8 and the window 10 of the valve 8, the gas flow rate is reduced to 30-40%. If the manometric system 3 is not tight, the adjusting spring 14, abutting the threaded sleeve 16 through the lock washer 15 and the stem 13, stretches the sensing element 11, lifts the control disk 17 to the stop 9 through the distance sleeve 18 into the threaded sleeve 16, i.e. during a gauge malfunction system 3, the gas power regulator has 100% throughput.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- simplification of the design;

- improving the reliability of the gas regulator;

- automatic control of the power of the burner at low temperatures;

- saving heat carrier and electricity.
