<p>PURPOSE:To make it possible to surely perform both connecting and disconnecting operation of a piping in a short time and holding airtightness as well by connecting a moving pipeline side made into constitution for individually operating an elastic body attached to the outside of the outer pipe and a passage opening closing elastic body equipped to the inside of the inner pipe to a fixed pipeline side. CONSTITUTION:For the purpose of connecting a moving side pipeline and a fixed side pipeline 1 together, the connecting nozzle 2 of the moving side pipeline is formed in a duplex tube consisting of an outer pipe 3 and an inner pipe 4 with communicating ports 3a, 4a provided therein respectively, and an elastic body 5 possible to swell out is attached to the outside of the outer pipe 3. Moreover, an elastic body 6 for opening/closing a passage for raw material or the like is provided in the inside of the inner pipe 4 for partitioning off flow of pressure liquid supplied into the duplex tube so as to divide the same into two parts in circular direc tion, and the elastic body 5 on the outside of the outer pipe 3 and the elastic body 6 provided in the inside of the inner pipe 4 are constituted so as to be possible to operate individually. The connecting nozzle 2 constituted in such a way is connected to the fixed side pipeline 1 so as to be inserted therein while, being elastic body 5 attached to the outside of the outer pipe 3 is swelled out with operation of the pressure liquid, and constituted so as to be con nected to the fixed side pipeline 1 in close contact thereto.</p> |
