Description

Technical Field

[0001] The present invention relates to the technical field of water supply equipment, and in particular to an intelligent non-negative pressure variable frequency water supply equipment. Background Art

[0002] Water supply equipment is closely related to people's lives. At present, the non-negative pressure water supply equipment in the prior art generally adopts variable frequency constant pressure control technology, that is, the water outlet pressure of the equipment always supplies water at a constant pressure according to the pressure set by the user. Since the actual water supply pressure required by the equipment is related to the building height, static water pressure and frictional loss, and the building height and static water pressure are unchanged, but the frictional loss changes with the change of water consumption. If the water outlet pressure of the equipment always remains constant according to the user-set pressure, then the pressure at the user end will inevitably change with the change of water consumption. Therefore, this water control technology must have certain problems: First, the water flow size changes with the change of water consumption; Second, the pipes in the user's home are prone to burst. In addition, the water supply equipment in the prior art is equipped with a pressure stabilizing tank to ensure the stability of the water supply pressure. However, the water in the pressure stabilizing tank has poor fluidity and poor water quality due to maintaining the water supply pressure stability for a long time. When the municipal water supply pressure is insufficient, the water supply equipment cannot actively provide pressure for voltage stabilization. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides an intelligent non-negative pressure variable frequency water supply equipment that is environmentally friendly, can actively replace the water in the pressure stabilizing tank, and actively supplements pressure when the municipal water supply pressure is insufficient.

[0004] The technical solution of the present invention: An intelligent non-negative pressure variable frequency water supply equipment, including an equipment base, a vacuum suppressor for suppressing negative pressure generated in the water supply system, a pressure stabilizing tank for stabilizing the water pressure of the water supply equipment, a butterfly valve for controlling the water flow, a check valve for preventing water flow back, and a water pump for providing power for the water supply work. The intelligent non-negative pressure variable frequency water supply equipment further includes a water supply pipeline, a pneumatic pump for stabilizing the air pressure in the water supply equipment, a pneumatic tank connected to the equipment base, and a bistable device for controlling the pressure in the pneumatic tank and the pressure stabilizing tank to remain stable. The pneumatic tank and the pressure stabilizing tank are connected in parallel to the water supply pipeline, and the bistable device is installed on the water supply pipeline.

[0005] Adopting the above technical solution, since the pneumatic tank and the pressure stabilizing tank are connected in parallel to the water supply pipeline, therefore, by adjusting the pressure in the pneumatic tank, the water pressure in the pressure stabilizing tank can be adjusted. When the municipal water supply pressure is insufficient or the water consumption is large, the bistable device controls the pneumatic pump to actively supplement pressure for the water supply equipment. When the water consumption is small or the internal pressure of the water supply equipment is large due to environmental factors, the bistable device controls the pneumatic pump to reduce the power, so that the internal pressure of the water supply equipment returns to normal. This can greatly improve the service life of the water supply equipment, ensure that the equipment does not malfunction, and can also make the water flow provided by the water supply equipment remain stable.

[0006] Further setting of the present invention: The bistable device includes a first detection unit for detecting the air pressure in the pressure tank, a second detection unit for detecting the water pressure in the pressure stabilizing tank, a controller for controlling the output power of the air pump, and a feedback unit for feeding back the detection results of the first detection unit and the second detection unit to the controller. The controller is electrically connected to the feedback unit and the air pump respectively.

[0007] With the above technical solution, since the bistable device includes a first detection unit, a second detection unit, a controller and a feedback unit, the water pressure in the pressure stabilizing tank is detected by the first detection unit, and the air pressure in the pressure tank is detected by the second detection unit. The first detection unit and the second detection unit transmit the detection results to the controller through the feedback unit. If the detection results show that the air pressure is too high or too low, the controller controls the air pump to adjust the power, so that the air pressure and water pressure in the water supply device are kept stable in real time.

[0008] Further setting of the present invention: An external pipeline connected to the pressure stabilizing tank and an electric valve connected to the external pipeline are provided on the pressure stabilizing tank. The bistable device further includes a timing element. The user can set the time on the timing device according to needs. The timing element is electrically connected to the feedback element, and the controller is electrically connected to the electric valve.

[0009] With the above technical solution, since an external pipeline connected to the pressure stabilizing tank and an electric valve connected to the external pipeline are provided on the pressure stabilizing tank, and the bistable device further includes a timing element, the user can set the electric valve to open every certain period of time according to needs. When the time set on the timing device arrives, an electrical signal is transmitted to the controller through the feedback element, and the controller controls the electric valve to open. The water in the pressure stabilizing tank is discharged from the external pipeline, so that the water in the pressure stabilizing tank can be cleaned regularly and the water quality can be ensured to be good.

[0010] Further setting of the present invention: When the time set on the timing element reaches, the controller controls the electric valve to open for 1 minute.

[0011] With the above technical solution, since the controller controls the electric valve to open for 1 minute when the time set on the timing element reaches, such a setting can ensure that the opening time of the electric valve is not too long to cause waste of water resources. At the same time, the 1-minute opening time is sufficient to replace the water in the pressure stabilizing tank and ensure good water quality in the pressure stabilizing tank.

[0012] Further setting of the present invention: The time set by the timing element is one cycle every 24 hours. When 24 hours are reached, the controller controls the electric valve to open. After the electric valve is closed, the timing element starts timing again.

[0013] Adopting the above technical solution, it is a specific embodiment of the present invention. Since the time set by the timing element is one cycle every 24 hours, that is, the water in the pressure stabilizing tank is actively replaced once a day, it can better ensure the good quality of the water provided by the water supply equipment.

[0014] Further setting of the present invention: Maintenance openings are respectively provided at the connection ends of the air pressure tank and the pressure stabilizing tank with the equipment base, and sealing covers are provided on the maintenance openings, and the sealing covers are detachably installed on the maintenance openings.

[0015] Adopting the above technical solution, since maintenance openings are respectively provided at the connection ends of the air pressure tank and the pressure stabilizing tank with the equipment base, and sealing covers are provided on the maintenance openings, and the sealing covers are detachably installed on the maintenance openings, it can ensure that the equipment can be conveniently maintained after a failure occurs.

[0018] As Figure 1-2 shown, an intelligent non-negative pressure variable frequency water supply equipment includes an equipment base 1, a vacuum suppressor 2 for suppressing negative pressure generated in the water supply system, a pressure stabilizing tank 3 for stabilizing the water pressure of the water supply equipment, a butterfly valve 4 for controlling the water flow, a check valve 5 for preventing water flow back, and a water pump 6 for providing power for the water supply work. The intelligent non-negative pressure variable frequency water supply equipment further includes a water supply pipeline 7, an air pressure pump 8 for stabilizing the air pressure in the water supply equipment, an air pressure tank 9 connected to the equipment base 1, and a bistable device 10 for controlling the pressure in the air pressure tank 9 and the pressure stabilizing tank 3 to remain stable. The air pressure tank 9 and the pressure stabilizing tank 3 are connected in parallel to the water supply pipeline 7, and the bistable device 10 is installed on the water supply pipeline 7.

[0019] Since the air pressure tank 9 and the pressure stabilizing tank 3 are connected in parallel to the water supply pipeline 7, therefore, by adjusting the pressure in the air pressure tank 9, the water pressure in the pressure stabilizing tank 3 can be adjusted. When the municipal water supply pressure is insufficient or the water consumption is large, the bistable device 10 controls the air pressure pump 8 to actively supplement pressure for the water supply equipment. When the water consumption is small or the internal pressure of the water supply equipment is large due to environmental factors, the bistable device 10 controls the air pressure pump 8 to reduce the power, so that the internal pressure of the water supply equipment returns to normal. This can greatly improve the service life of the water supply equipment, ensure that the equipment does not fail, and can also make the water flow provided by the water supply equipment remain stable.

[0020] The bistable device 10 includes a first detection unit for detecting the air pressure in the pressure tank 9, a second detection unit for detecting the water pressure in the pressure stabilizing tank 3, a controller for controlling the output power of the air pressure pump 8, and a feedback unit for feeding back the detection results of the first detection unit and the second detection unit to the controller. The controller is electrically connected to the feedback unit and the air pressure pump 8 respectively.

[0021] Since the bistable device 10 includes a first detection unit, a second detection unit, a controller and a feedback unit, the water pressure in the pressure stabilizing tank 3 is detected by the first detection unit, the air pressure in the pressure tank 9 is detected by the second detection unit, and the first detection unit and the second detection unit transmit the detection results to the controller through the feedback unit. If the detection results show that the air pressure is too high or too low, the controller controls the air pressure pump 8 to adjust the power so that the air pressure and water pressure in the water supply equipment are kept stable in real time.

[0022] An external pipeline connected to the pressure stabilizing tank 3 and an electric valve connected to the external pipeline are provided on the pressure stabilizing tank 3. The bistable device 10 further includes a timing element. The user can set the time on the timing device according to needs. The timing element is electrically connected to the feedback element, and the controller is electrically connected to the electric valve.

[0023] Since an external pipeline connected to the pressure stabilizing tank 3 and an electric valve connected to the external pipeline are provided on the pressure stabilizing tank 3, and the bistable device 10 further includes a timing element, the user can set the electric valve to open every certain period of time on the timing device. When the time set on the timing device arrives, an electrical signal is transmitted to the controller through the feedback element, and the controller controls the electric valve to open. The water in the pressure stabilizing tank 3 is discharged from the external pipeline, which can ensure that the water in the pressure stabilizing tank 3 is cleaned regularly and the water quality is good.

[0024] When the time set on the timing element arrives, the controller controls the electric valve to open for 1 minute.

[0025] Since when the time set on the timing element arrives, the controller controls the electric valve to open for 1 minute, such a setting can ensure that the opening time of the electric valve is not too long to cause waste of water resources. At the same time, the 1-minute opening time is sufficient to replace the water in the pressure stabilizing tank 3 completely and ensure good water quality in the pressure stabilizing tank 3.

[0026] The time set by the timing element is one cycle every 24 hours. When 24 hours are reached, the controller controls the electric valve to open. After the electric valve is closed, the timing element starts timing again.

[0027] As a specific embodiment of the present invention, since the time set by the timing element is one cycle every 24 hours, that is, the water in the pressure stabilizing tank 3 is actively replaced once a day, it can better ensure good water quality provided by the water supply equipment.

[0028] The connection ends of the pressure accumulator 9 and the pressure stabilizing accumulator with the equipment base 1 are respectively provided with inspection openings 11, and the inspection openings 11 are provided with sealing covers 12, and the sealing covers 12 are detachably mounted on the inspection openings 11.

[0029] Since the connection ends of the pressure accumulator 9 and the pressure stabilizing accumulator with the equipment base 1 are respectively provided with inspection openings 11, the inspection openings 11 are provided with sealing covers 12, and the sealing covers 12 are detachably mounted on the inspection openings 11, it can ensure that the equipment can be conveniently inspected after a failure.
