The utility model relates to a manual and pneumatic dual-purpose control valve, and relates to the field of fire fighting equipment. According to the manual and pneumatic dual-purpose control valve, a first cavity and a first
piston are arranged in a valve body, and an air inlet and an air outlet are formed in the first cavity; a second cavity is formed in the air cylinder, and a second
piston is arranged in the second cavity in a sliding mode; one end of the pressing arm is rotationally connected with the valve body, a limiting groove is formed in the other end of the pressing arm, and the other end of the first
piston extends out of the valve body and abuts against the bottom wall of the pressing arm; one end of the rotating arm is rotatably connected with the valve body through a rotating shaft, and the other end abuts against the second piston. One end of the rotating shaft is fixed to the rotating arm and connected with the limiting groove in a limiting mode, and a
handle is fixed to the rotating shaft. The control valve is of a pressing arm type structure, does not need to replace any part after being started, and can be repeatedly used; meanwhile, the control valve has a manual
operation mode and a pneumatic
operation mode and can be quickly opened, so that the fire extinguishing agent can be quickly released to a protection area.
