A double-door flap valve of a large high-temperature and high-frequency action RTO system

Abstract

The utility model relates to a double -open door flap valve of large -scale high temperature high frequency action RTO system belongs to exhaust gas treatment equipment technical field, solves the problem that the existing large -scale high temperature flap valve often appears broken axle fault, cannot on -the -spot dismount maintenance, including door frame welding frame, the middle part of door frame welding frame is provided with two groups of flap valve exhaust inlet, the upper side of flap valve exhaust inlet is provided with the valve plate respectively, the valve plate is fixedly connected with valve plate pivot through valve plate connecting arm, one end of valve plate pivot is rotatably connected with the inner bearing seat of door frame welding frame middle part, the other end of valve plate pivot is rotatably connected with the outer bearing seat of hydraulic cylinder support outer end, the fixed end of flap valve drive hydraulic cylinder is connected with hydraulic cylinder support through hydraulic cylinder hinged support, the telescopic end of flap valve drive hydraulic cylinder is fixedly connected with valve pivot end portion through valve shaft connecting swing arm, it is reasonable in design, compact structure, firm connection, effectively solve the problem that slender axle is easy to break, and dismount and maintain conveniently, and the practicality is strong.
