Description

Technical Field

[0001] The utility model relates to the technical field of coupling tanks, in particular to a floor heating coupling tank. Background Art

[0002] Floor heating is the abbreviation of floor radiation heating. It uses the entire floor as a radiator, and evenly heats the entire floor through the heat medium in the floor radiation layer. It supplies heat to the indoor room through the ground in the form of radiation and convection heat transfer to achieve the purpose of comfortable heating. The floor heating coupling tank is a key component in the floor heating system. It mainly plays the role of buffering and dividing the pressure, ensuring that the primary pump of the wall-mounted boiler and the secondary pump of the floor heating operate independently without interfering with each other.

[0003] The traditional coupling tank only couples the flow. When the water flows through the coupling tank, the residual impurities in the water will cause the pipeline to be blocked. The existing filter element is set inside the tank body, which is inconvenient to disassemble and cannot be cleaned or replaced in time. Therefore, those skilled in the art provide a floor heating coupling tank to solve the problems raised in the above background technology. Utility Model Content
