Abstract
(EN)
A check valve (1) comprises: a vessel body (2) that includes a cylindrical valve-accommodating section (21), a flow-in section (22) formed at one end of the valve-accommodating section (21), a flow-out section (23) formed at the other end of the valve-accommodating section (21), and a valve seat (24) that protrudes from the inner circumferential surface of the valve-accommodating section (21); and a valve (3) that is disposed in the vessel body (2) and that can move in the axial direction.
(FR)
L'invention concerne un clapet de non-retour (1) qui comprend : un corps de contenant (2) qui comprend une partie de logement de clapet cylindrique (21), une partie d'entrée de flux (22) formée à une extrémité de la partie de logement de clapet (21), une partie de sortie de flux (23) formée à l'autre extrémité de la partie de logement de clapet (21), et un siège de clapet (24) qui fait saillie de la surface circonférentielle interne de la partie de logement de clapet (21) ; et un clapet (3) qui est disposé dans le corps de contenant (2) et qui peut se déplacer dans la direction axiale.
(JA)
