Latch valve and flow control device using the same

摘要

There are provided a latch valve consuming less power, having a simpler structure, and guaranteeing reliable valve operation, there is provided a flow control device comprising a plurality of latch valves connected in series, and the second to the last latch valves, among the latch valves connected in series, include an additional outflow path constantly communicating with a space part between a support body and a plunger, respectively, to allow water from an inlet to constantly flow out to the additional outflow paths.

主权项

1. A flow control device comprising:
first and second latch valves connected in series, wherein each of the first and second latch valves comprises an inflow path and an outflow path formed in a housing, a solenoid having a coil wound thereon, a support body having an inlet connected to the inflow path and an outlet connected to the outflow path, a diaphragm having the support body inserted therein, and a plunger lifted or lowered by a magnetic force induced by the coil to open and close the outlet, and wherein the second latch valve includes an additional outflow path constantly communicating with a space part between the support body and the plunger, to allow water from the inlet of the second latch valve to constantly flow out to the additional outflow path.
