Triple Interlinked Quick-Acting Gate Valve for Coke Oven Flue (opening time <1s)

Core Product Features:
1. Millisecond-level rapid response: Opening time is strictly controlled within 1 second, far exceeding the 3-5 second response speed of conventional valves in the industry. It can quickly cut off or open the flue gas flow, blocking risks immediately in emergency situations (such as gas leaks or abnormal pressure), improving the system's safety level.
2. Triple linkage protection: Integrating a triple control mechanism of "mechanical linkage + electrical interlock + PLC signal feedback," it avoids misoperation caused by the failure of a single control. When the valve operates, it simultaneously triggers signal interaction between upstream and downstream equipment, ensuring coordinated operation of the coke oven flue gas system and the gas collection and purification units, preventing process disconnection.
3. Designed to withstand harsh operating conditions: The valve body is made of high-temperature resistant alloy material (ZG35Cr24Ni7SiN, etc.), capable of withstanding the high-temperature environment of 800-1200℃ in coke oven flue gas; the sealing surface adopts a hard alloy overlay welding process, which is wear-resistant and corrosion-resistant, solving the problem of valve sealing performance loss caused by flue dust and corrosive gases.
4. Lightweight operation and maintenance: The eccentric structure design reduces valve opening and closing resistance, and with an electric actuator (manual emergency operation optional), daily control can be completed by a single person; the valve body has no complex cavities, and periodic maintenance only requires cleaning the sealing surface, reducing downtime for maintenance.

Product application areas:
Coke oven heating system: As a core component of the coke oven body, it can realize rapid reversal and precise adjustment of flue gas flow, ensuring stable heating process.
Equipment maintenance and safety isolation: Used for quick and safe shutdown of equipment during system maintenance or emergencies, achieving reliable area isolation.
Environmental emission control: Acting on the terminal flue, it controls the leakage of harmful gases through reliable sealing, meeting environmental protection regulations.
