Pneumatic high-temperature angle seat valve for papermaking equipment

The invention discloses a pneumatic high-temperature angle seat valve for papermaking equipment. The angle seat valve comprises a valve body. A valve port is arranged in the valve body. A valve coveris fixedly connected to the side end of the valve body. The upper end of the valve cover is fixedly connected with a heat dissipating pipe. Two rows of rotating wheels distributed vertically and symmetrically are fixedly installed on the inner wall of the heat dissipating pipe. A pneumatic actuator is fixedly connected to the upper end of the heat dissipating pipe. Two air inlets distributed vertically are fixedly connected to the side end of the pneumatic actuator. A valve rod is arranged at the lower end of the pneumatic executor. The lower end of the valve rod penetrates through the heat dissipating pipe and the valve cover and is fixedly connected with a valve clack. A ring-shaped groove is formed in the side of the lower end of the valve clack. A second rubber gasket is fixedly connected into the ring-shaped
