Wall-mounted furnace and coaxial smoke pipe connector assembly thereof

Abstract

The invention discloses a coaxial smoke pipe connector assembly comprising a connector body. The connector body is provided with an air inlet channel; a smoke exhausting channel is coaxially arranged on the middle portion of the air inlet channel; and the connector body is provided with an exhausting flow limiting ring matched with the smoke exhausting channel and an air inlet flow limiting ring matched with the air inlet channel. In the assembling and using process, by means of cooperation of the exhausting flow limiting ring and the air inlet flow limiting ring, the channel area of the air inlet channel and the channel area of the smoke exhausting channel are adjusted at the same time, and therefore the adjustable range of the area specific value of channel ports of the coaxial smoke pipe connector assembly is effectively widened, and the overall work condition adaptive capacity and work performance of a wall-mounted furnace are remarkably improved. The invention further discloses the wall-mounted furnace applying the coaxial smoke pipe connector assembly.

Description

Technical field [0001] The invention relates to the technical field of wall-hung boiler supporting components, and in particular to a coaxial smoke pipe joint assembly. The invention also relates to a wall-hung boiler using the coaxial smoke pipe joint assembly. Background technique [0002] As a separate component, the coaxial smoke pipe joint plays a role in connecting the wall-hung boiler and the coaxial smoke pipe. [0003] Under normal circumstances, a restrictor ring is installed between the coaxial smoke pipe joint and the sheet metal parts of the boiler body to adjust the size of the air inlet channel. By selecting a suitable air intake passage opening area, it is ensured that the air intake passage and the flue gas exhaust passage have a suitable ratio, so that the combustion working condition of the wall-hung boiler reaches the best effect. [0004] In the above way, the size of the air intake passage is adjusted to ensure the proper passage opening area ratio, and the op...

AI Technical Summary

Problems solved by technology

[0005] However, although the existing coaxial smoke pipe joints can meet the basic operation needs of the wall-hung boiler, due to its own structural limitations, the assembly position of the restrictor ring is relatively single, which not only limits the adjustable range of the channel port area ratio, but also Restricts the overall working condition adaptability and working performance of the wall-hung boiler
