Title: Check valve
Inventor: MIYAZAKI MASAYASU
IPC: F16K15/14
Filed: 2017-10-30
Abstract: To provide a check valve which can prevent air oxidization and saprophyte contamination even after repeating discharge of the content.SOLUTION: At the time of discharge, the pressure applied to a container is transferred to a fluid body to bring a plug member away from an annular seat seal part of an elastic film such that the plug member moves to a discharge port side. When a movement of the plug member toward the discharge port side is restricted to stop by a projection of the elastic film and a cylindrical member, a spherical seal surface expands which seals by bringing the elastic film and the plug member at a vicinity of an exit side of the annular seat seal part into a tight contact by the pressure of the fluid body, which also expands a thinned part of the elastic film such that the fluid body is discharged and flown out from a tip part of the discharge port with the thinned part as a fluid body flow channel. Then, at the same time as stopping discharge of the fluid body, the spherical seal surface for sealing by being in tight contact with the elastic film elastically shrinks, and the plug member moved to the discharge port side of the elastic film is instantly retracted to the annular seat seal part side, and thus the plug member and the annular projection are tightly sealed to obtain a complete back-flow preventing function.SELECTED DRAWING: Figure 1
