Abstract
Method for the manufacture or repair of a globe valve. The valve housing (1) is assembled by welding out of two or more parts around a closing member (4) shaped as a part of the face of a globe and provided with a flow opening (3), and the shaft (5) of rotation of the closing member is attached to the closing member. Before the shaft (5) of rotation of the closing member is installed in its place, the closing member (4) is turned in the housing (1) so that the point (8) of fastening of the shaft of rotation becomes positioned facing the first flow duct (6) of the housing, and the shaft of rotation is inserted into the closing member through this flow duct (6) and attached to the closing member (b 4). The end of the closing member (4) placed facing away from the shaft (5) of rotation is pressed against the sealing face (7') of the second flow duct (6') of the housing, and this sealing face (7') is ground by means of the end of the closing member, or the end placed at the side of the shaft of rotation is pulled against the other sealing face, and this sealing face is ground by means of the end placed at the side of the shaft of rotation.
