LATCH VALVE AND FLOW CONTROL DEVICE USING THE SAME |
摘要 |
Provided is a simpler, more efficient, and more reliable latch valve. The latch valve includes an inflow path and an outflow path formed in a housing; a solenoid having a coil wound thereon; a permanent magnet positioned at an upper portion of a plunger and latching the plunger when the plunger is lifted; a spring positioned between the permanent magnet and the plunger; 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 the plunger lifted or lowered by a magnetic force induced by the coil to open and close the outlet, wherein an additional outflow path constantly communicating with a space part between the support body and the plunger is provided to allow a flow to be generated in the additional outflow path even when the plunger is closed. |

1. A latch valve comprising:
an inflow path and an outflow path formed in a housing; a solenoid having a coil wound thereon; a permanent magnet positioned at an upper portion of a plunger and latching the plunger when the plunger is lifted; a spring positioned between the permanent magnet and the plunger; 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 the plunger lifted or lowered by a magnetic force induced by the coil to open and close the outlet, wherein an additional outflow path constantly communicating with a space part between the support body and the plunger is provided to allow a flow to be generated in the additional outflow path even when the plunger is closed. |
