Abstract
The utility model relates to a flameout natural gas automatic cut-off device of a combustion gun, which comprises the combustion gun which is connected in an incinerator in a penetrating way, wherein the combustion gun is externally connected with a gas pipeline outside the incinerator, a purple light flame detector and an infrared temperature sensor are arranged on the combustion gun towards the muzzle position of the combustion gun, the purple light flame detector and the infrared temperature sensor are connected with an external controller of the incinerator, the controller is connected with a cut-off valve, the cut-off valve is arranged on the gas pipeline, a U-shaped pipe section with one end bent downwards is arranged on the gas pipeline behind the cut-off valve, and a check valve is arranged at the bottommost end of the U-shaped pipe section.
Description
Technical Field
The utility model relates to a combustion gun structure, in particular to an automatic flameout natural gas cutting device for a combustion gun.
Background
In the existing natural gas incinerator, a burning gun is mostly directly adopted to supply gas for burning in the incinerator, the burning gun is flameout or the special condition that flame is reduced under the condition of insufficient combustible oxygen in the incinerator is possible, if the special condition cannot be found in time, a valve of a gas pipeline cannot be closed in time, explosive gas and backfire are extremely easily formed, and the burning safety cannot be guaranteed.
Disclosure of Invention
The automatic flameout natural gas cutting device for the combustion gun is simple in structure, capable of effectively monitoring and controlling natural gas supply and combustion and good in safety performance.
The technical scheme adopted by the utility model is as follows: the utility model provides a flame-out natural gas automatic cutout device of burning rifle, is including wearing the burning rifle in burning furnace, burning rifle is burning external gas pipeline of burning furnace, its characterized in that: still include purple light flame detector, infrared temperature sensor, a controller, the shut-off valve, the check valve, purple light flame detector, infrared temperature sensor all are towards burning rifle muzzle position setting on burning the rifle, purple light flame detector, infrared temperature sensor connects and burns burning furnace outer control ware, the controller connects the shut-off valve, the shut-off valve sets up on gas pipeline, be equipped with one end U type pipeline section of bending down on the gas pipeline behind the shut-off valve, the bottom of U type pipeline section is provided with the check valve.
Furthermore, another cut-off valve is arranged on the gas pipeline behind the check valve.
Furthermore, a flow regulating valve behind the block valve is arranged on the gas pipeline, and the flow regulating valve is connected with the controller.
Furthermore, an igniter is arranged on the combustion gun and connected with the controller.
The utility model adopts the purple light flame detector to detect the flame combustion intensity and whether the flame is extinguished, simultaneously combines the infrared temperature sensor to detect the flame combustion temperature, and the two are jointly used for judging the signal to the controller, the controller acts on the special condition that the flame gun is extinguished or the flame is reduced under the condition of insufficient combustible oxygen in the furnace, controls the closing of the two cut-off valves, or adjusts the flow regulating valve to control the flow reduction when the combustion is insufficient, thereby avoiding various explosion hidden dangers.
Drawings
FIG. 1 is a schematic view of the structure of the present invention.
In the figure: the device comprises an incinerator 1, a combustion gun 2, a gas pipeline 3, a purple light flame detector 4, an infrared temperature sensor 5, a controller 6, a first cut-off valve 7, a U-shaped pipe section 8, a check valve 9, a second cut-off valve 10 and a flow regulating valve 11.
Detailed Description
The following further description is made in conjunction with the accompanying drawings and examples.
FIG. 1 shows: the utility model provides a burning rifle flameout natural gas automatic cutout device is including the cross-under burning the burning rifle 2 in burning furnace 1, burning rifle 2 is burning external gas pipeline 3 of burning furnace, purple light flame detector 4, infrared temperature sensor 5 all is towards burning rifle muzzle position setting on burning the rifle, purple light flame detector, infrared temperature sensor connects and burns burning furnace external control unit 6, the controller connects and sets up first on gas pipeline, two shut-off valves 7, 10, be equipped with one end U type pipe section 8 of bending down on the gas pipeline between two shut-off valves, the bottom of U type pipe section is provided with check valve 9, establish flow control valve 11 behind the second shut-off valve, flow control valve connects the controller.
On the basis of the embodiment, an igniter connecting controller can be arranged on the combustion gun, so that ignition and safety performance can be further controlled.
