Abstract: The present invention relates to a butterfly valve with improved airtightness, in which an insertion hole having an end portion formed to be inclined inward is formed on the circumference of a body configured to prevent leakage of a fluid therein by being in contact with the outer side of a disk, and a sealing member is inserted into the insertion hole, such that the fluid therein is prevented from being leaked between the body having a body sheet and the body sheet when a gap is generated since the shape of the body sheet is changed due to interference caused by changes in the internal temperature of a flow path formed in the body. When a pipe is fastened to both sides of the butterfly valve to allow the fluid to move therein, the pipe presses the sealing member and a contact member and pushes the sealing member into the insertion hole, such that the sealing member is fixated and prevented from being separated. Most of all, even if the fluid inside the body is leaked between the body and the body sheet due to the deformation of the body sheet, the sealing member is able to prevent the fluid from being leaked to the outside, thereby improving airtightness of the butterfly valve.
