摘要： PROBLEM TO BE SOLVED: To provide an assembling method for an expansion pipe coupling, by which a ring member can be assembled in a state where it is positioned in an annular circumferential groove without dividing an outer sleeve member and also by which inserting work of the ring member in relation to the annular circumferential groove can be quickly and easily performed with a little laborious work, by devising a mounting structure and a mounting procedure of the ring member. SOLUTION: After a ring member 5 capable of being elastically deformed in the radial direction by being partially cut in the circumferential direction is inserted into an annular circumferential groove 2b through a cutout part 2c of an outer sleeve material 2, an inner sleeve material 1 is inserted into the outer sleeve material 2 in which the ring member 5 is inserted, the ring member 5 is relatively moved in the axial direction along the outer peripheral surface of the inner sleeve material 1 while being elastically deformed in the expanding direction in the annular circumferential groove 2b, and the ring member 5 is fitted and fixed in a recessed groove 1b formed on the outer periphery of the inner sleeve material 1.

摘要： PURPOSE:To reduce an outer measurement of a side to which new pipes of a case are connected by sandwiching the new pipes between divided cases to be connected to each other from a diameter direction, and a providing a connection part which connects the new pipes to the case. CONSTITUTION:An arranged water pipe A and a flange short pipe B, respectively having pipe axes X and Y arranged on the same level in a horizontal direction are sandwiched in a diameter direction by means of vertically divided cases 3 and 4, and fixed by bolt connection of flanges 9. Second flanges 8 of the divided cases 3, 4 are formed on a connection part which connects the flange short pipe B to a case 1, with the flange short pipe B being sandwiched by the cases 3, 4 to be connected to each other. An inner diameter (d) of the second flange 8 is larger than an outer diameter D of the flange short pipe B which is sandwiched by the second flanges 8. The flange short pipe B is sandwiched between the upper and lower second flanges 8 through second seal members S2, and connected along a pipe axis Y thereof in a relatively slidable manner.

摘要： PURPOSE:To prevent leakage of fluid through a discharge passage for a long period by a method wherein a holding mechanism is located on the inner side than the outlet of the discharge passage and an operation mechanism is mountable on and demountable from the connection case side. CONSTITUTION:A holding mechanism 17 to be capable of holding a plug 13 in a closed position comprises a male screw 15 formed on the outer peripheral surface of a plug 13; and a female screw 16 formed in the inner peripheral surface of a bushing 11. Meanwhile, an operation mechanism 14 causes insertion of a columnar insertion rod 18 in a cap 10 such that the insertion rod is in a watertight state and coaxial with a boss axis X and slidable along the boss axis X and a deformed shaft part 19 insertably and retractably fitted in the one end face of a plug 13 is formed at the tip of the insertion rod 18 and mountable on and demountable from the connection case 1 side through a nipple 7 togetherwith a T-pipe tees 8 and a stop valve 9. This constitution causes prevention of leakage of fluid without differently forming a through-hole in the wall of the connection case 1.

摘要： PURPOSE:To let alone the section of a pipe cut off in a condition that circulation of fluid in the pipe is not stopped, and make the section hardly corrosive. CONSTITUTION:An annular contact member 13 for pressing an annular seal member 12, which can be brought into close contact along an annular section 4a of a fluid transport pipe 1 in a condition that a flow of fluid in the pipe is not interrupted, against the section 4a is provided. The annular seal member 12 is additionally provided in a pressing surface 13a of this annular contact member 13, a reaction force receiving member 14 for receiving reaction force according to pressing to a side of the section 4a of the annular contact member 13 is opposed to an opposite side to the pressing surface 13a of the annular contact member 13 and also provided capable of approaching/separating, the annular contact member 13 is connected to the reaction force receiving member 14, and further a connecting mechanism J capable of separation operating the annular contact member 13 from the reaction force receiving member 14 along a connecting direction thereof is provided.
