Beschreibung
Zusammenfassung:	The utility model belongs to the technical field of aviation valves, and discloses a pressure-adjustable spherical valve one-way valve structure which is characterized by comprising a one-way valve shell assembly, a valve seat and a pressure valve assembly, the pressure valve assembly is arranged in the valve seat in a vertically movable mode, and the valve seat is arranged in the one-way valve shell assembly. The interior of the one-way valve shell assembly is divided into three cavities through the pressure valve assembly and the valve seat, and the three cavities comprise a pressure valve assembly inlet, an inlet cavity in the front end of the pressure valve assembly, an outlet cavity in the circumferential direction of the one-way valve shell assembly and the pressure valve assembly and a pressure adjusting cavity in the rear end of the valve seat and the pressure valve assembly. The pressure regulating cavity is communicated with the pressure regulating port; the outlet cavity is communicated with the oi
