ライ弁。[Claims for Utility Model Registration] 1. In a butterfly valve in which a valve body is rotatably provided in a valve body via a valve shaft, a circumferential shape is provided on the periphery of the face of the valve body opposite to the valve opening operation direction. A butterfly valve characterized in that a plurality of projecting edges are formed, a plurality of small through holes are formed in each of the circumferential projecting edges, and a comb-like protrusion is formed at the top of each of the circumferential projecting edges. 2. The axes of the small through holes provided in the circumferential flange, which becomes the secondary side after the valve body is closed, are parallel to each other or in a direction in which the downstream side in the fluid flow direction is slightly open. butterfly valve. 3. The comb tooth-like protrusions provided on the circumferential protrusion that becomes the secondary side when the valve body is closed are arranged so that the axes of the slit-like channels formed between the protrusions are parallel to each other or are slightly open on the downstream side in the fluid flow direction. 2. The butterfly valve according to claim 1, wherein the butterfly valve is formed so as to be oriented in the opposite direction. 4. The axes of the small through holes provided in the circumferential flange that becomes the secondary side when the valve body is closed are parallel to each other or in a direction in which the downstream side in the fluid flow direction is slightly open, and the comb teeth are provided in the circumferential flange. 2. The butterfly valve according to claim 1, wherein the protrusions are formed such that the axes of the slit-like channels formed between the protrusions are parallel to each other or slightly open downstream in the fluid flow direction. .
