Beschreibung
Zusammenfassung:	The utility model relates to a valve assembly for an air brake double-loop braking main valve. The valve assembly comprises a body of the braking valve. The outer plane of the body is provided with three air holes integrally formed. The three air holes are uniformly distributed in the circumference. The inner circle and the outer circle of the body are provided with lip openings with inclined faces being sealed. The portion, with the air holes, of the plane is provided with a boss. According to the valve assembly for the air brake double-loop braking main valve, due to the fact that the shape and the structure of the valve are reasonably optimized, the leak tightness is improved, the production efficiency of production machining is high, the machining cost is low, bad defects are eliminated, and the implementation effect is good.
