摘要

FIELD: pipeline engineering. ^ SUBSTANCE: quick-detachable joint comprises two housings that are pressure-tightly interconnected. Each of the housings is pressure-tightly connected with the corresponding pipeline and receives the hollow tubular locking members and inserts. Each insert is provided with dummy first face and at least one through passage that passes through the side of the appropriate inset and enters the corresponding pipeline from the side of the face of the inset. The first seals are interposed between the sides of the insets and inner sides of the inserts. The first valving member is provided with solid walls and mounted inside the first housing. The first face of the first inserts that projects out from the first housing is provided with the first seat. The walls of the second valving member are provided with at least one port interposed between the third seal and fourth seal when the second valving member reciprocates between the end positions. ^ EFFECT: reduced leakage. ^ 10 cl, 9 dwg
