Title:
LIQUID LEVEL CONTROL METHOD
Document Type and Number:
Japanese Patent JPH03135610
Kind Code:
A
Abstract:
PURPOSE:To easily and surely control the liquid level with use of a simple and inexpensive device by using a siphon tube which contains two inverse U-shaped bend tube parts and a tube part that connects both U-shaped tube parts together. CONSTITUTION:A siphon tube 10 is set so that an inflow part 11 formed at one of two ends of the tube 10 faces to the inside of a liquid tank 1 together with an outflow port 12 formed at the other end facing to a liquid feed path 4 respectively. At the same time, a top part 14a of an inverse U-shaped bend tube part 14 set at the outflow side is set at a lower limit liquid level setting level L of the tank 1. Therefore the liquid is discharged through a flow path in the tube 10 owing to a head difference when the liquid level of the tank 1 is higher than the level L. Then the liquid is exhausted in the flow path at the position of a small opening 16 when the liquid of the tank 1 reaches a level equal to the part 14a of the tube 14. Thus the discharge of the liquid is surely stopped.
