The invention relates to a strengthened valve, which includes: a tube body, an external thread is set on an outer edge of the tube body; an elastic slip-piece, which is a hollow structure, is previously glued with the tube body as an air-tight condition; a sleeve, which is a hollow structure, an internal threaded hole is set on an inner edge of its top, the sleeve is slipped on the elastic slip-piece when the strengthened valve is put on a rim, the internal threaded hole of the sleeve is fastened on the external thread of the tube body, a bottom of the sleeve is against outer side of the rim; by composition of above structure, tolerance of the strengthened valve for centrifugal force effect may be strengthened that tire deflated condition may not happened during high speed driving, to thereby improve road safety.
