CHECK VALVE FOR WATER FEED DEVICE

摘要

PURPOSE: A check valve is provided to easily attach and detach an embedded housing while preventing the flow and noise of a check valve body, and to examine reverse flow from the outside. CONSTITUTION: A check valve for a water feeding device comprises a housing(22), an inspection key bolt(17), and a cover(14). The housing is composed of attach and detach knobs(23) formed on an external circumference; O-ring grooves(24) placed to the lower side of the attach and detach knobs; and valve guides(25) formed on an inner circumference. The inspection key bolt containing a stop ring groove(19) on a lower side has a fluid outflow hole(18). The cover contains an inspection hole(15) inserted by the inspection key bolt. The check valve for a water feed device examines the reverse flow of the fluid discharged from an inflow hole while being operated without vibration and noise. The components of the check valve are simply repaired and exchanged by easily attaching and detaching the housing.
