Coke oven flue gate valves can resolve technical issues in regulating gas flow within coke oven tail gas ducts.

The coke oven flue gate valve comprises a valve body and a valve core positioned within the valve body. The valve body is a hollow structure filled with refractory material. The hollow valve body structure and internal refractory filling enhance the gate valve's high-temperature resistance. The valve core comprises a valve plate made of refractory material and a valve stem connected to the plate. A lateral extension protrudes from the valve body's mid-section, housing the valve core within its groove. This lateral extension ensures the valve plate remains entirely within the valve body throughout its entire displacement stroke, guaranteeing smooth operation of the valve core during opening and closing. Simultaneously, it enhances sealing between the valve core (including plate and stem) and the valve body.

Coke oven flue gate valves effectively resolve the technical challenge of regulating flue gas flow in coke oven exhaust ducts. Offering superior technology, simple structure, low investment, and minimal operating costs, they facilitate precise and convenient adjustment and control of flue gas volume. This capability meets the demands of coke oven processes, particularly those concerning furnace temperature regulation.
