Abstract
PURPOSE:To obtain a high reliable check valve to perform its maintenance work further in small size, by utilizing the joint part of a piping line in a refrigerating cycle and mounting the check valve. CONSTITUTION:When a check valve 14 is built in a joint part 21, elastic members 28a, 28b made of rubber material or the like are firstly fitted to two root parts 16g, 16h of a crest part 16g in the check valve 14, and then there are internally peripherally fitted one side of an outer cylinder 16 of the check valve 14 to a pipe 10e while the other side to a union 22. Thereafter, a flared nut 23 is tightened to the union 22 to complete the joint part 21. The check valve is fixed to a piping by holding the crest part 16g together with a flange part 10i between the flared nut 23 and the union 22, further air-tightness processing means for the above is performed by arranging the elastic members 28a, 28b in a deformed state respectively with screw tightening force.
