Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to a gate valve used for a flue. Background Art

[0002] The calcination process of prebaked anode manufacturers produces a large amount of high-temperature flue gas, which needs to be transported through the flue; the high-temperature flue gas can be transported to waste heat boilers, thermal oil boilers and other systems through different flues for heat recovery and utilization. In order to achieve the reasonable distribution of flue gas, it is necessary to install a gate valve on the high-temperature flue to adjust the flue gas volume. Since the gate is in a high-temperature environment for a long time and needs to be adjusted frequently, the gate is easily damaged after a period of use. After the gate is damaged, the castable fragments in the gate will fall to the bottom of the gate box, which is not easy to remove, causing the gate to fail to fall into place; at the same time, the flue gate valve is in the dusty exhaust flue for a long time, resulting in the deposition of dust at the bottom of the gate valve, which will also affect the sealing of the gate to the flue, and thus make it difficult to adjust the flue gas volume.
