Description

Technical Field

[0001] The utility model relates to the technical field of fire row pieces, in particular to a combined fire row piece structure. Background Art

[0002] Household water heaters, gas stoves, and even lighters can all be considered as a type of burner. According to its working principle, a burner can be defined as a device that converts substances into heat energy through a chemical reaction called combustion - that is, air and fuel are mixed in appropriate proportions through a premixing device to ensure full combustion. Burners have a variety of classification methods based on their different properties;

[0003] After checking the public (announcement) number: CN210772161U, a combined fire row plate structure is disclosed. This technology discloses technical solutions such as "the fire row plate threaded connecting rod on the lower surface of the fire row plate is fixedly connected to the shunt pipe connecting port", and has technical effects such as "a fire row plate threaded connecting rod is installed under the fire row plate, and several threads on the fire row plate threaded connecting rod are used to cooperate with the shunt pipe connecting port below, so that they can be connected and fixed by rotating. The advantage of this is that it greatly facilitates users to install and disassemble the fire row plate";

[0004] Since the fire strip in the above scheme is connected by threads, the fire strip may vibrate and move during operation, especially in high temperature and high pressure environments. Over time, the threaded connection may produce fatigue cracks due to repeated vibration and loading, which will not only reduce the reliability and stability of the connection, but also may cause safety hazards; although the threaded connection allows disassembly and reassembly, in some cases, the disassembly process may become difficult due to overtightening or thread damage, increasing maintenance costs and time.
