Abstract

PURPOSE: To make a rubber weir free to level completely with a simple piping by providing a hollow spacer lengthwise in the inside of the weir while one end of the spacer is opened upward therein.
CONSTITUTION: When an erected rubber weir is levelled with the discharge of a sealed fluid, a fluid passage 17 communicated lengthwise is formed as the spacer 7 is extended. The fluid moves through the fluid passage 17 and is discharged quickly from a water running port.
