Attachment structure of joint destal of flexible pipe

摘要

Topic Just junction the joint destal with the flange coupling which becomes the barrel the attachment to be possible, airtight inspection is made unnecessary argon welding of the flexible pipe and the coupling as unnecessary, as for the coupling being form simple, the numbers of processes of cutting work process unit cost offer the attachment structure of the joint destal of the inexpensive flexible pipe few.SolutionsIt has the spigot 9, as it possesses rim flange 14 in on the one hand flexible pipe and 1a and flexible pipe 1b of the opposite side which has socket 12 and one end side at the same time by other end side it possesses left and right symmetrical circular arc section 17b by the left and right band plate one section 16b which the flange coupling 2 which becomes barrel 13 of the pair which inner circumference flange 15 lap facilities is done and the band plate two-fold is done and provides the respective long hole 18b providing boss 19 in the inside edge of each long hole, it consists of with the fastener 3 which it formed.
