According to a control method, a two-position two-way direct-acting type structure is adopted, the solenoid valve is opened after energization and is closed after deenergization, and a fluid medium flows into from the upper part of the valve body and flows out from the lower part of the valve seat. Compared with the prior art, the large-diameter direct-acting type high-pressure solenoid valve has the obvious advantages that (1) the diameter is large, the working pressure is high, the sustainable conduction time is long, and therefore, large-flow media can be continuously and stably supplied; (2) the action response speed is high (less than or equal to 10 ms), the solenoid coil of the solenoid valve is large, the sectional area of the valve core is large, so that large electromagnetic force can be generated, and therefore, the response speed is high.

The invention discloses a large-flow air-control corrugated pipe type pressure reducing valve. An inlet cavity (2), an outlet cavity (4), a damping cavity (6), a control cavity (7) and an unloading cavity (9) are sequentially arranged in a valve body from top to bottom. The large-flow air-control corrugated pipe type pressure reducing valve is characterized in that the front end of the valve inlet cavity (3) is externally provided with a bypass pipeline (23) communicating with the unloading cavity (9), and the acting force applied by a medium to a throttling valve element (13) is balanced. Compared with the prior art, the large-flow air-control corrugated pipe type pressure reducing valve has the remarkable beneficial effects that a metal corrugated pipe serves as a sensitive element of the pressure reducing valve, rigidity is small, sensitivity is good, the effective area is large and the mass is small, and therefore the kind of valve has the beneficial effects of being high in outlet pressure control precision, stable in pressure, large in flow, small in dynamic-static pressure difference, good in dynamic characteristic and the like; and the unloading cavity can be used for counteracting the acting force applied by the high-pressure gas medium to the throttling valve element, the opening conditions of the throttling valve element are improved, the loads of the sensitive element are reduced, and the service life of the metal corrugated pipe is prolonged.
