Description

Technical Field

[0001] The utility model relates to the technical field of chimney control, in particular to a chimney control device. Background Art

[0002] The multifunctional boiler chimney automatic opening and closing control device is developed on the basis of the original up-and-down lifting device. Generally, the potential safety hazard of a boiler is caused by the "chimney effect". Especially when the boiler is operating, as the hot air rises in the chimney, the generated air flow overflows, and the air outside the boiler fills in, resulting in instability in the air conditioning control inside the boiler. Therefore, it is inevitable to appropriately use "blocking" at the outlet to reduce the rapid overflow of hot air.

[0003] In different experimental environments of high-temperature furnaces, some require the inside of the furnace chamber to be airtight without gas flow (smoldering), and some require air flow to help the test object oxidize fully. Therefore, it is necessary to control the opening and closing of the chimney, which is a key component of the furnace ventilation circuit.

[0004] The existing opening and closing control of chimneys is usually electric control. When the power is off, the control of the chimney will be paralyzed. Summary of the Utility Model
