Description

Technical Field

[0001] This utility model relates to the field of industrial gas burner technology, specifically a safety configuration structure for an industrial gas burner solenoid valve. Background Technology

[0002] Industrial gas burners are the core heating elements of industrial furnaces and kilns. They provide heat to the furnaces and kilns by controlling the mixing and combustion of gas and combustion air. Solenoid valves, as key control components, are responsible for regulating the flow of gas and combustion air. Their safety configuration is directly related to the stability and safety of the furnace and kiln operation.

[0003] In existing technologies, gas solenoid valves mostly adopt a single valve body structure. The common solution is to rely on the sealing performance of a single solenoid valve to ensure the gas blocking effect. However, this method cannot deal with leakage problems caused by valve body wear or failure, which can easily lead to continuous gas leakage. Solenoid valves and power supply components often use a unified wiring method. Although this solution facilitates standardized production, it makes it difficult to distinguish the wiring of gas solenoid valves from combustion air solenoid valves, making it very easy to connect incorrectly during on-site installation or maintenance. At the same time, power supply cables are mostly marked with simple wire numbers. The common solution is to distinguish them by matching the wire numbers with circuit diagrams. However, in actual operation, it is difficult to quickly identify them when there is no circuit diagram, further increasing the probability of wiring errors. These problems may eventually lead to deflagration or even explosion accidents. Therefore, a safe configuration structure for industrial gas burner solenoid valves is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a safe configuration structure for an industrial gas burner solenoid valve, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety configuration structure for an industrial gas burner solenoid valve, comprising:

[0006] Gas solenoid valve, combustion air solenoid valve, three-prong wiring socket, four-prong wiring socket, first power plug, second power plug, first label and second label;

[0007] The gas solenoid valve is a dual solenoid valve series structure, and the gas solenoid valve is fixedly connected to a three-prong terminal block. The first pin, the second pin, and the ground pin of the three-prong terminal block are respectively connected to the neutral wire, the live wire, and the ground wire.

[0008] The combustion air solenoid valve is fixedly connected to a four-pin socket. The first, third, and ground pins of the four-pin socket are connected to the neutral, live, and ground wires, respectively. The second pin of the four-pin socket is not connected to any wire.

[0009] The first power plug is compatible with a three-pronged socket and is plugged in. The first power plug’s No. 1 socket, No. 2 socket and ground socket are respectively connected to the neutral wire, the live wire and the ground wire.

[0010] The second power plug is compatible with a four-pin socket. The first, third, and ground pins of the second power plug are connected to the neutral, live, and ground wires, respectively. The second pin of the second power plug is not connected.

[0011] The first label is fixed to the power supply cable of the gas solenoid valve, and the second label is fixed to the power supply cable of the combustion air solenoid valve. The first label and the second label are different colors, and the first label is labeled as the gas solenoid valve, while the second label is labeled as the combustion air solenoid valve. The dual solenoid valve series structure can form a double sealing protection, effectively reducing the risk of leakage from a single solenoid valve. The differentiated wiring design avoids accidental valve opening when the two are misconnected. The label marking further reduces the probability of wiring errors, thereby avoiding safety accidents such as deflagration and explosion, and significantly improving the safety and reliability of industrial gas burners.

[0012] Preferably, protective covers can also be added, which are respectively fitted onto the connection between the three-pronged socket and the first power supply plug, and the connection between the four-pronged socket and the second power supply plug.

[0013] Compared with the prior art, this utility model provides a safe configuration structure for an industrial gas burner solenoid valve, which has the following beneficial effects:

[0014] This invention utilizes a gas solenoid valve with two solenoid valves connected in series to achieve double sealing protection for gas flow, thus enhancing leak prevention. The differentiated wiring design between the three-pin and four-pin wiring sockets, and between the first and second power supply plugs, prevents power supply to the solenoid valve in case of incorrect connection, avoiding accidental opening of the gas solenoid valve. Furthermore, the use of first and second labels to identify the corresponding power cables allows for quick on-site identification, reducing the probability of wiring errors. These progressively designed features address the safety issues of wiring errors and single solenoid valve leaks that can easily lead to deflagration or even explosions in existing technologies, thereby improving the safety of industrial gas burners.

[0020] This utility model provides a technical solution: a safety configuration structure for an industrial gas burner solenoid valve. (Please refer to...) Figure 1 , Figure 2 and Figure 3 ,include:

[0021] 1. Gas solenoid valve; 3. Combustion air solenoid valve; 2. Three-prong wiring socket; 4. Four-prong wiring socket; 5. First power supply plug; 6. Second power supply plug; 7. First label; and 8. Second label.

[0022] The gas solenoid valve 1 is a dual solenoid valve series structure, and the gas solenoid valve 1 is fixedly connected to the three-prong terminal block 2. The first pin, the second pin, and the ground pin of the three-prong terminal block 2 are respectively connected to the neutral wire, the live wire, and the ground wire.

The first pin, the third pin, and the ground pin of the four-pin socket 4 are connected to the neutral wire, the live wire, and the ground wire, respectively. The second pin of the four-pin socket 4 is not connected.

[0024] The first power plug 5 is adapted to be plugged into the three-pronged socket 2. The first socket, the second socket and the ground socket of the first power plug 5 are respectively connected to the neutral wire, the live wire and the ground wire.

The differentiated wiring of the three-prong wiring socket 2, the four-prong wiring socket 4, the first power plug 5, and the second power plug 6, along with the different colored first label 7 and second label 8, not only reduces the probability of wiring errors, but also prevents power supply to open the valve even if the wiring is incorrect, thus comprehensively avoiding the risk of deflagration or explosion and enhancing core safety assurance.

The two ends of the protective sleeves are tightly fitted to the outer periphery of the socket and the outer periphery of the plug, respectively.
