Description

Technical Field

[0001] The utility model relates to the technical field of flame probes, in particular to a connection structure for multi-model compatible flame detection probes. Background Art

[0002] Burner boilers use different fuels (coal, oil, gas, etc.), and require different types of fire detection probes. According to the different characteristics of different fuel combustion spectra and different installation forms of different furnace types, the commonly used fire detection probes on the market can be mainly divided into integrated infrared fire detection probes, integrated ultraviolet fire detection probes, split infrared fire detection probes, and split ultraviolet fire detection probes. The installation and inspection of the fire detection probe requires connection through a fire detection installation pipe. The fire detection installation pipe passes through the embedded pipe on the outer wall of the furnace wall and is connected to the embedded pipe flange. It is fixed on the furnace wall, with the front end extending into the furnace of the boiler and the rear end located outside the furnace. The tail end of the fire detection installation pipe is connected to the fire detection probe, realizing the installation and fixation of the fire detection probe. Due to the different detection principles and methods of fire detection probes, different types of probes have different structural sizes, resulting in the need to match multiple types of installation pipe assemblies.

[0003] Currently, existing fire detection probes require different fire detection installation tubes to be selected according to the models of different fire detection probes. This will lead to a large number of fire detection installation tube models, which have disadvantages such as low matching degree with fire detection probes, poor compatibility, and high maintenance and manufacturing costs.
