Abstract

PURPOSE: To widen the extent of application of a check valve by equipping it with a manually operating mechanism which is to open the check valve.
CONSTITUTION: The body 6 of a check valve 1 is equipped with a manually operating mechanism (a) composed of a pillar 14a, a threaded rod 14 and a loose preventive nut 16. This provides possibility to open the check valve even by hand and thereby widens the extent of application of a check valve remarkably.
