Abstract
(EN)
This watertight testing device 21 has: a cylindrical core 22 internally fitted to a pipe joint part 1; a first seal member 23 that seals the space between the outer circumference of the core 22 and the inner circumference of one pipe 2; a second seal member 24 that seals a space between the outer circumference of the core 22 and the inner circumference of the other pipe 4; a first pressing member 25 that presses and compresses the first seal member 23 into a first seal member insertion space 46; a second pressing member 26 that presses and compresses the second seal member 24 into a second seal member insertion space 47; a moving device 27 that moves the first and second pressing members 25, 26 in the pipe axial direction A; and a testing fluid supply device 28 that supplies a testing fluid into a testing space 71.
(FR)
La présente invention concerne un dispositif d'essai étanche à l'eau 21 comprenant : un noyau cylindrique 22 ajusté à l'intérieur d'une partie de raccord de tuyau 1 ; un premier élément d'étanchéité 23 qui étanche l'espace entre la circonférence externe du noyau 22 et la circonférence interne d'un tuyau 2 ; un second élément d'étanchéité 24 qui étanche un espace entre la circonférence externe du noyau 22 et la circonférence interne de l'autre tuyau 4 ; un premier élément de pression 25 qui presse et comprime le premier élément d'étanchéité 23 dans un premier espace d'insertion d'élément d'étanchéité 46 ; un second élément de pression 26 qui presse et comprime le second élément d'étanchéité 24 dans un second espace d'insertion d'élément d'étanchéité 47 ; un dispositif de déplacement 27 qui déplace les premier et second éléments de pression 25, 26 dans la direction axiale A de tuyau ; et un dispositif d'alimentation en fluide d'essai 28 qui alimente en fluide d'essai un espace d'essai 71.
