ができる。 When the pump 1 is operated with the pressure tank 13 empty, water is pumped from the water source to the pump 1 via the check valve 5, and then through the discharge pipe 7 and the pumping pipe 9 to the sealing valve. 21 reaches the flow path 23. At this time, the valve body 29 is pushed down by the spring force of the push spring 43, and the valve cushion 35 is moved against the valve seat 37.
The pumped water passes through the passage 39 and applies pressure to the bypass valve 41, pushing it upward and opening it as shown in FIG. 2, causing the flow to flow. It flows from channel 23A through connecting pipe 11 into pressure tank 13. Since the bypass valve 41 can be opened widely regardless of the push spring 43, the valve body 29 is opened widely, compared to the case where the valve body 29 itself is slightly opened and water flows through the gap.
It can be operated with low noise and without vibration.

なく封圧弁２１を流れることができる。 When this water pumping operation is started and the pressure on the lower surface of the diaphragm 27 of the sealing pressure valve 21 increases, the diaphragm 27 overcomes the spring force of the push spring 43 and moves upward as shown in FIG. At the same time, the valve body 29 also moves upward, widening the gap between the valve body 29 and the valve seat 37, and closing the bypass passage 39 with the bypass valve 41. Since the gap between the valve body 29 and the valve seat 37 is wide open, pumped water can flow through the sealing pressure valve 21 without any hindrance.

When the pressure inside the pipe 7 reaches the closing pressure of the pressure switch 15, the pressure switch 15 closes and the pump 1 starts pumping operation.

利用容積が増えることになる。 In this way, when the pump 1 is repeatedly operated and stopped, the air auxiliary device 17 is connected to the pressure tank 13 each time.
Replenish air inside. When the air in the pressure tank 13 is replenished and the air in the pressure tank 13 increases, the upper limit water level L 1 and the lower limit water level L 2 of the pressure tank 13 become the upper limit water level L 3 and the lower limit water level shown in FIG.
It goes down like L 4 , upper limit water level L 3 and lower limit water level L 4
This increases the water level difference between the pressure tank 13 and the pressure tank 13.

有効利用容積を増大することができる。 In this case, the lower limit water level L 4 of the pressure tank 13 is set considerably low, and the compressed air in the pressure tank 13 is discharged by supplying water from the faucet that is higher than the amount of water pumped by the pump 1. No inconvenience will occur. That is, by using water in excess of the amount of water pumped by the pump 1, the pressure inside the discharge pipe 7 increases to the point where the pressure switch 15
When the pressure drops below the closing pressure of , the sealing pressure valve 21 closes as shown in FIG. 1, and the discharge of the compressed air in the pressure tank 13 is prevented. Therefore, the effective usable volume of the pressure tank 13 can be increased.

Even if the lower limit water level L 4 is set to be considerably low and water is supplied from a faucet, etc. in excess of the amount of water pumped by the pump 1, the compressed air in the pressure tank 13 will not flow out. Therefore, it is possible to increase the effective usable volume of the pressure tank 13. Furthermore, when the pump performs water pumping operation when the pressure tank 13 is empty, the water is pumped into the pressure tank 13 via the bypass valve 41 which is not affected by the spring force of the push spring 43, so the valve body of the sealing pressure valve 21 The sealing pressure valve 21 can be operated with low noise without causing the valve 21 to vibrate.
