Abstract
PURPOSE:To form a valve box and a short pipe in one body simply and still rapidly without generating thermal stress in important portion of the valve by connecting the valve box and the short pipe together with using a female crowned groove on inner circle of a socket for the short pipe on the valve box and a male crowned projection on the short pipe. CONSTITUTION:A female crowned groove 3 is formed on inner circle of a socket 2, for a short pipe 4 of thin metal pipe, provided on a valve box 1 of a sluice valve and the like, and after inserting the short pipe 4 in the socket 2, the short pipe 4 is formed on a portion into the shape of a male crowned projection 5 coinciding with the shape of the female crowned groove 3 by a pipe expanding means of bulging or roll forming and the like with keeping it in inserted condition, and thereby the valve box 1 and the short pipe 4 are connected together in one body.
