Abstract
PURPOSE: To supply a proper quantity of air to a pressure tank by few structural parts and all the time, in this water-service installation provided with the pressure tank.
CONSTITUTION: Under a condition that a pump 1 is stopped, water in a pressure tank 3 is pushed out and water supply is continued, only the first sluice valve 12 is opened, water in an air supply tank 7 is discharged through a drain pipe 11 and the outside air is taken into said tank 7 through a valve 10 by negative pressure generated at that time. When air 6 in the pressure tank 3 flows out with water and is insufficient, and the inner pressure reaches the pressure of the lowest limit, the pump 1 is started by means of a pressure switch 4. The water in the pressure tank 3 flows into the air supply tank 7 through a feed water pipe 5 because the first sluice valve 12 is closed and the second sluice valve 13 is opened at the same time as the starting of the pump 1. Thus, air in said tank 7 is compressed, and supplied into the pressure tank 3 through an air supply pipe 8 by pressure difference by water-level difference before and behind a check valve 9.
