The pressure of the compressed gas inside the tank is used to send the water stored in the tank into the water supply network, and the pressure inside the tank also drops. When the pressure drops to the minimum working pressure, the control cabinet turns on the power to the water pump, and the water pump restarts. This cycle repeats continuously, which allows the water pump to avoid running for a long time and helps extend the service life of the water pump. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides the following technical solution: an energy-saving constant pressure water supply and exhaust device, including a mounting plate 1, a water storage tank 2 fixedly mounted on the left side of the top of the mounting plate 1, a diaphragm-type pressure water tank 5 fixedly mounted on the right side of the top of the mounting plate 1, a water pipe 15 fixedly mounted on the right side of the water storage tank 2, a rubber flexible joint 23 fixedly mounted on the surface of the water pipe 15, a gate valve 24 and a check valve 25 fixedly mounted on the surface of the water pipe 15, a water pump 17 fixedly mounted at one end of the gate valve 24, and a fixed water pipe 22 fixedly mounted at the output end of the water pump 17. A connecting water pipe 7 is fixedly installed at one end of the 22. A pressure gauge transmitter 11 and a pressure gauge 12 are fixedly installed on the surface of the connecting water pipe 7. A water outlet 6 is fixedly installed at the right end of the connecting water pipe 7. A connecting hose 18 is fixedly installed on one side of the connecting water pipe 7, and one end of the connecting hose 18 is fixedly connected to the bottom of the diaphragm-type pressure water tank 5. A butterfly valve 13 is fixedly installed on the surface of the connecting hose 18. A pressure relief pipe 3 is fixedly installed on the front side of the water storage tank 2, and one end of the pressure relief pipe 3 is fixedly connected to the surface of the connecting water pipe 7. An air inlet 4 is fixedly installed on the top of the diaphragm-type pressure water tank 5.

[0022] According to Boyle's gas law, for a given mass of gas at a given temperature, the product of pressure and volume is constant. When water pump 17 operates, water is delivered to the water supply network, and excess water enters the diaphragm-type pressure tank 5. The water chamber expands, compressing the gas inside the tank, while the gas chamber shrinks, causing the pressure inside the tank to rise. When the pressure reaches the maximum working pressure P2, control cabinet 21 cuts off the power to water pump 17, and water pump 17 stops. At this time, the pressure of the compressed gas inside the tank is used to send the water stored in the tank into the water supply network, causing the water chamber to shrink, the gas chamber to expand, and the pressure inside the tank to drop. When the pressure drops to the minimum working pressure P1, control cabinet 21 turns on the power to water pump 17, and water pump 17 restarts. This cycle repeats continuously. The commissioning procedure for the diaphragm-type pressure tank 5 should follow the principle of filling with water first, then with nitrogen. Water can be supplied using the city's water supply system. When filling with water, open the vent valve. Once the air in the water chamber is completely expelled, stop filling and close the vent valve. Begin inflation by first turning the pointers of the electric contact pressure gauge 12 to the required maximum and minimum pressure positions. Then, open the inflation nozzle to inflate. When the inflation pressure reaches the maximum pressure P2, inflation is complete. Close the inflation nozzle. Because the diaphragm-type air bladder can store energy, the water pump 17 does not need to run for extended periods during periods of low water usage, saving electrical energy and extending the pump's lifespan. The water tank has a service life of 17 days, and the water supply pressure can be set arbitrarily to ensure the user's water supply pressure. The water replenishment pipe 9 facilitates the replenishment of water into the water storage tank 2, while the drain pipe 8 facilitates the cleaning and discharge of mud and sludge from the water storage tank 2. The overflow port 10 allows water to flow out when there is too much water in the water storage tank 2, and the float valve allows for easy closing or opening of the overflow port 10 to ensure water storage. Excess water inside tank 2 can flow out through pressure relief pipe 3. Regarding the control cabinet 21, since the pressure gauge transmitter 11, pressure gauge 12, and water pump 17 are all electrically connected to the control cabinet 21, it is easy to control the start and stop of water pump 17. The spare port 16 allows for the connection of water pipe 7, providing an extra outlet 6. A sealing cap is threaded onto one side of the spare port 16, allowing it to be opened by unscrewing the cap and closed by unscrewing it. The support rod 19 facilitates the installation of the diaphragm-type pressure water tank 5 on top of the mounting plate 1, thus providing an advantage for easy installation. The mounting block 14 and connecting hole 20, with three mounting blocks 14, allow for suspended installation of the diaphragm-type pressure water tank 5, making this device more versatile in its installation methods. All electrical equipment in this device is powered by an external power source.

[0023] In one aspect of this embodiment, the support rod 19 facilitates the installation of the diaphragm-type pressure water tank 5 on the top of the mounting plate 1, thus the support rod 19 has the advantage of facilitating the installation of the diaphragm-type pressure water tank 5. As for the mounting block 14 and the connecting hole 20, since there are three mounting blocks 14, it is convenient to suspend the diaphragm-type pressure water tank 5, making the device more versatile in terms of installation methods.

[0024] In one aspect of this embodiment, the water supply pipe 9 facilitates the replenishment of water into the water storage tank 2, while the drain pipe 8 facilitates the cleaning and discharge of mud and sludge from the water storage tank 2. The overflow port 10 allows excess water in the water storage tank 2 to flow out through the overflow port 10. The float valve allows for the closure of the overflow port 10 or the opening of the overflow port 10, allowing excess water in the water storage tank 2 to flow out through the pressure relief pipe 3.

[0025] In one aspect of this embodiment, the control cabinet 21 is electrically connected to the pressure gauge transmitter 11, pressure gauge 12, and water pump 17, which facilitates the control of the start and stop of the water pump 17. The spare port 16 is designed to facilitate the connection of the water pipe 7 to have an extra outlet 6. A sealing cap is threaded on one side of the spare port 16, so the spare port 16 can be opened by unscrewing the sealing cap, and conversely, it can be closed.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
