[0003] The existing pressure tank is provided with an air bag inside, and air is injected into the pressure tank to adjust the pressure, so as to control the pressure on the air bag and play a role of stabilizing pressure. However, when the existing pressure tank is in use, water will flow in and out of the air bag for a long time during the long-term use of the pressure tank, and the pressure in the tank will constantly change, which will inevitably cause leakage, resulting in the air bag being unable to maintain a specific position. When the air pressure is insufficient and the air bag is dumped, it will affect the control of the water flow and it is impossible to obtain a stable pressure control. In addition, the air bag usually needs to be disassembled for cleaning, which is troublesome and takes a long time to operate, affecting normal water use. In addition, each disassembly and assembly will affect the seal, affecting the normal use of the pressure tank. Utility Model Content

DETAILED DESCRIPTION

[0016] See also Figure 1-2As shown, the technical solution adopted in this specific embodiment is: it comprises an outer box 1, an air pressure tank 2, the air pressure tank 2 is arranged in the outer box 1, a control chamber 1-1 is arranged on the top of the outer box 1, an air pressure pump 3 and a control system 9 are arranged in the control chamber 1-1, a three-way pipe 6 is arranged on the air pressure tank 2, the three-way pipe 6 is connected to the air pressure pump 3 through an air pipe 14, a pressure sensor 5 is arranged on the three-way pipe 6, the pressure sensor 5 is electrically connected to the control system 9, the control system 9 is electrically connected to the air pressure pump 3, and a water pipe is arranged at the bottom of the air pressure tank 2. 10. The water pipe 10 is provided with a water inlet solenoid valve 7 and a water discharge solenoid valve 8. The water inlet solenoid valve 7 and the water discharge solenoid valve 8 are electrically connected to the control system 9. In this embodiment, the pressure sensor detects the pressure in the air pressure tank. When the pressure drops to the minimum value, the pressure sensor signal is triggered. The air pressure pump is controlled by the control system to inflate and pressurize. When the pressure in the air pressure tank reaches the maximum set value, the control system controls the air pressure pump to stop, thereby realizing automatic pressure regulation, without manual daily inspection and maintenance, to ensure the stability of water supply;

[0017] In addition, regular cleaning of the air pressure tank is also an important part of daily maintenance. In this embodiment, automatic control is performed by setting inlet and drain solenoid valves on the water pipe, wherein the water pipe 10 includes an inlet pipe 10-1 and a drain pipe 10-2, the inlet solenoid valve 7 is set in the water inlet direction of the inlet pipe 10-1, and the drain solenoid valve 8 is set in the drain direction of the drain pipe 10-2;

[0018] The cleaning cycle can be set on the control panel, or it can be started manually. When cleaning begins, the water inlet solenoid valve is first controlled to be closed, and the drain solenoid valve remains open to discharge the sewage in the air bag. After emptying, the drain solenoid valve is closed, and the water inlet solenoid valve is opened to supply water. When the air bag is filled with clean water, the pressure in the air pressure tank returns to normal, the pressure sensor sends a signal, the control system closes the water inlet solenoid valve, and opens the drain solenoid valve again to discharge sewage. During the drainage process, the pressure in the air pressure tank continues to decrease. The pressure sensor has set the minimum air pressure detection value during drainage. When the value is reached, a signal is sent to the control system. The control system closes the drain solenoid valve again and opens the water inlet solenoid valve. This cycle is repeated until the cleaning work is completed, that is, the water inlet solenoid valve is opened again, the drain solenoid valve is closed, and the air bag is replenished with water, so that the air pressure tank returns to normal pressure. The pressure sensor sends a signal to the control system again, and the control system controls the drain solenoid valve to open. Both solenoid valves are in the open state for normal water supply.

[0019] More specifically, a one-way valve 4 is provided on the air pipe 14, and the one-way valve 4 is connected to one side of the three-way pipe 6. The one-way valve is provided so that the air pump can only pump air into the air pressure tank, and the air in the air pressure tank will not flow back, thereby ensuring the pressure replenishment effect.

[0020] To be more specific, a water inlet interface 11 and a drainage interface 12 are respectively provided on both sides of the outer box 1. The water inlet interface 11 is connected to the water inlet pipe 10-1, and the drainage interface 12 is connected to the drainage pipe 10-2. The water inlet interface and the drainage interface are provided on the outer box to facilitate connection with external pipelines, thereby facilitating the installation and use of the equipment.

[0021] To be more specific, a control panel 15 is provided on the control chamber 1-1, and the control panel 15 is electrically connected to the control system 9. The maximum and minimum pressure detection values ​​for daily pressure replenishment can be conveniently set through the control panel to realize automatic pressure replenishment, as well as high and low pressure values ​​during cleaning, thereby realizing automatic cleaning.

[0022] To be more specific, the control chamber 1-1 is also provided with an air pressure observation window 16, and the position of the air pressure observation window 16 corresponds to the position of the air pressure pump 3. During daily maintenance or use, not only can specific parameters be observed through the control panel, but also the working status of the air pump can be observed through the air pressure observation window.

[0023] The working principle of the utility model: after the equipment is installed, the minimum value and the maximum value of the air pressure detected by the pressure sensor 5 are set through the control panel 15, so as to control the air pressure pump 3. During use, when the air pressure in the air pressure tank 2 drops to the set minimum value, the pressure sensor 5 sends a start signal to the control system 9, and the control system 9 starts the air pressure pump 3 to inflate and pressurize. When the pressure value reaches the set maximum value, the pressure sensor 5 sends a stop signal to the control system 9, and the control system 9 sends a stop signal to the air pressure pump 3, and the air pressure pump 3 stops pumping and completes a pressure replenishment operation. When the air bag needs to be cleaned, the control system 9 controls the water inlet solenoid valve 7 to close and the water discharge solenoid valve 8 to open, and the sewage in the air bag 13 is discharged. After emptying, the water discharge solenoid valve 8 is closed, and the water inlet solenoid valve 7 is opened to supply water. When the clean water fills the air bag, Bag 13, the pressure in the air pressure tank 2 returns to normal, the pressure sensor 5 sends a signal, the control system 9 closes the water inlet solenoid valve 7, and opens the drain solenoid valve 8 again to drain sewage. During the drainage process, the pressure in the air pressure tank 2 continues to decrease. The pressure sensor 5 has set the minimum air pressure detection value during drainage. When the value is reached, a signal is sent to the control system 9. The control system 9 closes the drain solenoid valve 8 again and opens the water inlet solenoid valve 7. This cycle is repeated until the cleaning work is completed, that is, the water inlet solenoid valve 7 is opened again, the drain solenoid valve 8 is closed, and the air bag 13 is replenished with water, so that the air pressure tank 2 returns to normal pressure. The pressure sensor 5 sends a signal to the control system 9 again, and the control system 9 controls the drain solenoid valve 8 to open. Both solenoid valves are in the open state for normal water supply. The entire process is operated through the control panel 15, and no other excessive manual operations are required.

Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
