Claims

[Scope of Claim for Utility Model Registration] 1. A check valve chamber and a ball valve chamber that communicate vertically are formed between the population side and the outlet side, and the ball valve chamber has a rotatable valve chamber with a flow hole. A ball valve is disposed through a pair of pole seats, and a check valve body is provided in the check valve chamber so as to be able to slide up and down with a ball valve handler and to block the flow hole of the ball valve. A ball valve equipped with a check valve mechanism in which check valve gaskets for closing the flow hole are arranged under the valve body in accordance with the positional relationship of the pole seat with respect to the ball valve. 2. A practical use characterized in that the check valve gasket has a concave lower surface and directly blocks the outlet of the flow hole of the ball valve which is held between the left and right sides by a pair of pole seats. A ball valve equipped with a check valve mechanism according to claim 1. 3. The check valve gasket is formed with a convex lower surface, and by fitting the convex surface into the through hole of the upper ball seat of the pole seat that clamps the ball valve from above and below. A ball valve equipped with a check valve mechanism according to claim 1, which closes the outlet side of a flow hole of the ball valve. 4. A ball valve equipped with a check valve mechanism according to claim 3, wherein the through-hole portion of the upper ball seat has an inner circumferential edge formed in an upright manner.
