Description

Technical Field

[0001] The utility model belongs to the technical field of flame welding, in particular to a flame welding gas control device. Background Art

[0002] Quartz is a mineral found widely in the Earth's crust. Its extremely high melting point and excellent optical and physical properties make it widely used in semiconductors, optical instruments, chemical laboratory equipment, and other fields, providing an important material foundation for the development of modern industry and science and technology. During the production and processing of quartz, welding techniques are required to firmly connect two or more quartz glass components together to form complex structures or devices.

[0003] There are many methods for quartz welding, and flame welding is the most commonly used one. It uses a high-temperature flame generated by an oxygen-fuel gas mixture to melt the weldment and solder, thereby achieving a connection. Currently, there are some flame welding equipment on the market. For example, a welding gun that can improve the flame intensity is disclosed on the China Patent Network, and its announcement number is CN220892241U. This welding gun can be used for quartz welding, but there are some defects and deficiencies that need to be improved: (1) Some existing flame welding equipment requires workers to hold the welding gun when using it, which is inconvenient. After a long time of welding, it will cause fatigue to the workers, and it is impossible to weld multiple quartz pieces at the same time, making it difficult to meet the needs of large-scale quartz welding; (2) Some existing flame welding equipment is difficult to adjust the flame at any time during welding. The flame type needs to be manually adjusted every time a welding operation is performed, which has low work efficiency. Therefore, in response to the above problems, the flame welding gas control device provided by the present invention is of great significance. Utility Model Content

At this time, the oxygen and hydrogen in the oxygen storage pipe 5 and the hydrogen storage pipe 6 can be introduced into the mixing chamber of the igniter 15 respectively through the oxygen guide pipe 29 and the hydrogen guide pipe 30. After the oxygen and hydrogen are fully mixed in the mixing chamber of the igniter 15, they can enter the flame welding gun 1 through the air outlet 16 and the air outlet pipe 22, and enter the welding nozzle of the flame welding gun 1.

At this time, oxygen and hydrogen can be introduced into the multiple flame welding guns 1 at the same time through the multiple oxygen gas guide tubes 29 and the hydrogen gas guide tubes 30, so that batch welding operations can be performed on multiple quartzes at the same time, thereby effectively meeting the large-scale quartz welding needs. Before the welding operation, the flame type in the flame welding gun 1 is a seed fire for preheating and maintaining the welding flame. After the oxygen and hydrogen are introduced into the flame welding gun 1 through the gas control component, the seed fire in the flame welding gun 1 can be automatically converted into a high-temperature flame of a hydrogen and oxygen mixture. When the welding operation is completed and the gas guide valve 13 is closed, the flame type in the flame welding gun 1 automatically changes from a high-temperature flame of a hydrogen and oxygen mixture to a seed fire without the need for manual adjustment, thereby greatly improving the efficiency of the entire welding work.
