ABSTRACT:
Disclosed is a solenoid valve for controlling water supply. The solenoid valve includes a constant flow control member having a chamber at one side of a connecting pipe branched from a body which has an outlet port, the chamber temporarily accommodating water and quantitatively supplying the water by using a flow control sheet, and a low-pressure flow control member tightly installed in an inlet port which communicates with the connecting pipe of the chamber, the low-pressure flow control member having a hollow body to enclose the flow control sheet. A first flow channel is formed between an outer periphery of the low-pressure flow control member and an inner periphery of the inlet port, and a second flow channel is formed by a hole of the low-pressure flow control member, a passage of the flow control sheet, and a hole of the resilient member.
