Document Type and Number:
Japanese Patent JP6694580
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a water valve apparatus which may prevent water leak from a connecting part on a flow path by preventing a main flow path of a water valve main body part to have an excessive higher pressure and may reduce operation burden upon establishment.SOLUTION: A water valve apparatus 1 of the present invention comprises a water valve main body part 10 in which a main flow path 8 allowing water or functional water to flow is formed at its inner section, and a water ejecting part 32 which is formed at a downstream side of the main flow path 8 and on which a water ejecting port 44 ejecting the water or functional water flowing through the main flow path is formed. An opening sectional area of the water ejecting port is smaller than a flow path sectional area of the main flow path. The water ejecting part comprises pressure releasing means R, 46 which release pressure in the main flow path by communicating the main flow path and the air when a pressure P in the main flow path reaches a predetermined pressure P1 or more.SELECTED DRAWING: Figure 6
