[0002] In the process of coke oven operation, the diffusion valve and the water seal valve are important components; among them, when the pressure of the gas collecting pipe is too high, the diffusion valve releases the gas in the diffusion mode to maintain the safe operation of the coke oven system; the water seal valve forms a certain height of water seal in the pipeline to avoid the backflow of the gas to the gas collecting pipe or the carbonization chamber;

[0003] When the pressure of the coke oven system is too high and the gas needs to be released, in order to make the gas flow out smoothly through the diffusion valve, the water level in the water seal valve needs to be temporarily lowered to destroy the water seal so that the gas can flow; when the pressure of the coke oven system is reduced to the safe range, the diffusion valve is closed, and the water seal in the water seal valve needs to be reformed to continue to prevent the discharge of the gas;

[0004] However, if the water seal valve cannot be closed in time when the diffusion valve diffuses the gas, the gas may leak to other areas through the water seal valve, causing environmental pollution and safety hazards, so the diffusion valve and the water seal valve need to be linked to synchronize the opening and closing of the two; in addition, when one of the diffusion valve or the water seal valve fails and needs to be repaired, the linkage assembly between the two cannot be affected by disassembly, so the coke oven automatic diffusion water seal valve linkage device is needed to solve the above problems.
