Abstract
A fluid control valve capable of reducing or preventing a foam from being retained inside and reducing the likelihood or preventing the other fluid equipment placed downstream from causing a failure due to the foam, and a droplet discharging device using the fluid control valve, are provided. Fluid control valves and include a tank through which fluid flows, an inflow port through which fluid flows into the tank, an outflow port through which fluid flows out from the tank and a valve body for opening and closing the inflow port or the outflow port, the inflow port being provided below the outflow port.
Claims1
A droplet discharging device, comprising:
- a droplet discharging head provided with a plurality of nozzles to discharge a liquid material having fluidity;
- a cleaning device to clean a peripheral part of the nozzles;
- a cleaning liquid supply part to discharge cleaning liquid to the cleaning device;
- a first supply flow passage to supply the liquid material to the droplet discharging device;
- a second supply flow passage to supply the cleaning liquid to the cleaning liquid supply part;
- and
- a fluid control valve to control flow of the liquid material flowing in the first supply flow passage and flow of cleaning liquid flowing in the second supply flow passages, respectively, the fluid control valve having:
- a tank through which fluid flows;
- an inflow port through which fluid flows into the tank;
- an outflow port through which fluid flows out from the tank;
- and
- a valve body to open and close the inflow port or the outflow port,
- the inflow port being provided below the outflow port.
