都合であり、安全性にも欠けるものである。When the automatic opening/closing valve 6 is opened, the pressure water in the pressure tank 2 flows into the jet bonding section 14 through the water supply pipe 7, and this inflowing water generates a negative pressure section in the jet pump section 14. At this time, the backwash water from the pressure tank 2 is cut off by the check valve 9, so the water in the air supply tank 4 is sucked by the jet pump section 14, and the water is removed from the pressure tank.
This slanted air supply tank 4 returns to the suction side 1a of the pump 1, which is located upstream from the 1nJd inside the pump 1, together with the driving water from the pump 1 via the automatic on-off valve 6 and the drain pipe 12.
The inside becomes negative pressure, and atmospheric air is taken into the air supply tank from the air intake valve 8. When the automatic opening/closing valve 6 is closed, the pressure water in the pressure tank 2 flows backward from the jet pump part 14 into the air supply tank 4. This inflow water closes the air intake valve 8, and the air in the air replenishment tank 4 9IC#'i check valve 9. It is forced into the pressure tank 2 through the air supply pipe 10. By the way, the automatic opening/closing valve 6 is operated periodically by a skin timer or the like, but if the timing of opening and closing is not perfect, the air taken into the air supply tank 4 will flow through the automatic opening/closing valve 6, the drain pipe 12, and then the pump 1. This can cause problems such as a drop in bonde pressure and an inability to pump water. Therefore, when the water level in the air supply tank 4 reaches the L-L water level, the water level detection means 16 opens the contact 16b, opens the control circuit of the automatic on-off valve 6 (not shown), and Close 7
Do it like this. In this way, the above problem can be solved. However, if the water level detection means 16 is attached directly to the lower cover abI/Uf of the air supply 1114, this is inconvenient in terms of maintenance and also lacks safety.

This is a mounting device configured to be detachably attached to the mounting screw portion 4f of b. The operation of the device configured in this way will be explained. When the automatic opening/closing valve 6 is opened, high pressure water in the pressure tank 2 flows into the jet pump section 14 via the water supply pipe 7.
This inflow water creates a negative pressure portion within the jet pump section 14. At this time, since the backflow water from the pressure tank 2 is cut off by the check valve 9, the water in the air supply tank 4 is sucked by the jet pump section 14, and is automatically combined with the driving water from the pressure tank 2. Open/close valve6. The water flows back through the drain pipe 12 into the pump 1 or to a low-pressure water source such as the suction side 1a of the bonder 1 located upstream from the pump 1. Therefore, the inside of the air supply tank 4 is kept under negative pressure, and the air is taken into the air supply tank through the air intake valve 8. Next, when the automatic on-off valve 6 is closed, the high pressure water in the pressure tank 2 flows backward through the jet pump section 14 and flows into the air supply tank 4, and this inflow water closes the air intake valve 8.
The air in the air supply tank 4 is supplied through a check valve 9 and an air supply pipe 1.
