The invention discloses a high-flow high-pressure pneumatic switch valve which comprises a main valve and an electromagnet, wherein the electromagnet is located on the main valve and fixed on the main valve through a bolt. The electromagnet comprises an electromagnet support frame, an upper electromagnet body and a lower electromagnet body. The main valve comprises a valve body, a valve deck, a valve sleeve, a spring, a valve core seat and a valve core, wherein the valve core comprises a cone valve core body with a threaded hole, a valve core rod and a rubber ring. The high-flow high-pressure pneumatic switch valve can solve the problems that when high-pressure gas passes through an ordinary valve, the energy available value of the gas is reduced due to friction and the like, and the amount of the gas flowing through the ordinary valve is quite small, and can improve the energy utilization rate of a device in which compressed air is used for storing and supplying energy and the like; and meanwhile, the high-flow high-pressure pneumatic switch valve is simple in structure and is only composed of the electromagnet and the main valve, so that complexity and instability of the device are reduced, when the high-flow high-pressure pneumatic switch valve needs to be opened or closed, just the electromagnet needs to be powered on or powered off, the electromagnet responds fast, and therefore the response speed of opening and closing the valve is extremely high, the effect that the high-flow high-pressure pneumatic switch valve is opened and closed rapidly can be achieved, and the high-flow high-pressure pneumatic switch valve can meet the requirement on fast response of pneumatic automobiles and other vehicles.
