Description

TECHNICAL FIELD

[0001] The present application belongs to the field of water supply equipment, in particular to a sectional water supply device. BACKGROUND

[0002] The existing water supply device for city high-rise buildings generally comprises a large motor set and a small motor set, when the water consumption is low, the large motor set is stopped and only the small motor set is used, when the water consumption is high, the large motor set and the small motor set are used simultaneously.

[0003] The small motor set in the existing water supply device for high-rise buildings generally drives one pump body with one motor to supply water to the whole building, when the lower floor and the high floor use water simultaneously, the water pressure of the lower floor is particularly large, while the water pressure of the high floor is very small, even without water, at this time, the large motor set is started to supply water to the building, only when the middle and lower users almost do not use water, the small motor set can meet the water supply of the high users, and the probability is very small, so that the large motor set is frequently started to meet the water supply of the high users, such water supply device is particularly power-consuming and not energy-saving and environment-friendly. SUMMARY

[0004] In view of the defects of the existing small motor set water supply for city high-rise buildings, the technical problem to be solved by the present application is to provide a sectional water supply device with stronger water supply capacity.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present application, the present application is realized by the following technical measures: a sectional water supply device, comprising:

[0006] a plurality of pump bodies, the shafts of the pump bodies are connected through a shaft coupling, and an outer pump body is further connected with a motor, and the motor provides power for the pump bodies simultaneously;

[0007] a tap water pipe I, which is directly connected with the user water supply pipes, and a one-way valve is arranged at the connection between the tap water pipe I and the user water supply pipes;

[0008] a tap water pipe II, one end of which is connected with the tap water pipe I, and the other end is connected with the pump bodies through an inlet pipe, and a one-way valve is arranged on the inlet pipe of the tap water pipe II, except for the pump body connected with the motor;

[0009] an outlet pipe, which is used to connect the pump bodies and the user water supply pipes, and a one-way valve is arranged on the outlet pipe, the tap water in the tap water pipe II is discharged into the user water supply pipes through the outlet pipe after being pressurized by the pump bodies,

[0010] an electromagnetic valve is arranged on the outlet pipe, except for the outlet pipe of the pump body farthest from the motor, and a pressure sensor is arranged in each user water supply pipe, and the pressure sensor and the electromagnetic valve are connected through a controller.

[0011] This segmented water supply device sets the number of pumps according to the height of the floors, thus reducing the number of floors that a single pump can supply. When the water consumption of a single floor is small, water is supplied directly through the tap water pipe I. Only when the pressure sensor detects a large water consumption will the controller open the solenoid valve, so that the water supplied from the tap water pipe II to the pump is pressurized before flowing into the user's water supply pipe. This method has a stronger water supply capacity than a single pump supplying water to the entire floor.

[0012] Furthermore, the segmented water supply device also includes a connecting pipe, with each adjacent pump body connected by a connecting pipe. One end of the connecting pipe is connected to the inlet pipe, and the other end is connected to a one-way valve. This design allows pressurized water from the pump body on the lower floor to enter the adjacent pump body through the connecting pipe when the pump body on the lower floor is not pressurizing the water supply to the user. This increases the kinetic energy for supplying water to the upper floors, resulting in a faster water output.

[0013] Compared with the prior art, the advantages of the present invention are: the segmented water supply not only allows for the use of a smaller motor to provide kinetic energy, but also results in better water supply performance. When a connecting pipe is added, the water supply kinetic energy reaches its maximum value. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example

[0020] Please refer to Figure 1 This embodiment provides a segmented water supply device including a pump body 1, a motor 2, a water pipe I 3, a water pipe II 6, a water outlet pipe 8, and a connecting pipe 11. There are two pump bodies 1, connected by a coupling. A motor 2 is fixed to the outside of the right pump body 1, providing power to both pump bodies 1. The water pipe I 3 is directly connected to each user's water supply pipe 4, and a one-way valve 5 is fixed at the connection point to ensure that water can only flow into the user's water supply pipe 4 and cannot flow back. The left end of the water pipe II 6 is connected to the water pipe I 3, and the right end is preferably closed. Two inlet pipes 7 are connected to the water pipe II 6, and the other ends of the two inlet pipes 7 are connected to the pump body 1 to supply water. The inlet pipe 7 on the right side of the pump body closest to the motor is a through pipe, while the inlet pipe 7 on the left side is... A one-way valve 5 is fixed inside the inlet pipe 7 on the pump body furthest from the motor. Each of the two pump bodies 1 has an outlet pipe 8 fixed at its lower end. The outlet pipe 8 is connected to the user's water supply pipe 4, and a one-way valve 5 is also fixed on the outlet pipe 8, so that the water pressurized by the pump body 1 can enter the user's water supply pipe 4. A solenoid valve 9 is also fixed on the outlet pipe 8 on the right pump body near the motor. The solenoid valve 9 is located above the one-way valve 5. The solenoid valve 9 is connected to the inlet pipe 7 at the upper end of the left pump body 1 through a connecting pipe 11. The connecting pipe 11 is preferably located below the one-way valve 5 on the inlet pipe 7. The solenoid valve 9 controls whether the water flows into the user's water supply pipe 4 or the connecting pipe 11. Pressure sensors 10 are fixed inside both user's water supply pipes 4. The pressure sensor 10 on the right is connected to the solenoid valve 9 through a controller.

[0021] In operation, motor 2 drives both pump bodies 1 to rotate simultaneously. When the water supply from water pipe I3 ​​is insufficient to meet the needs of the entire floor, some tap water enters the two pump bodies 1 through water pipe II6 and is pressurized by the pump bodies 1. When pressure sensor 10 detects that the water consumption of the lower-floor users is low, the controller will close the solenoid valve 9. The pressurized water from the right-hand pump body 1, which is closest to the motor, will enter the left-hand pump body 1 through the connecting pipe 11 to pressurize the water flow together, making the water pressure of the middle and upper floors greater and meeting the water demand of the entire floor. When the lower-floor users also need pressurized water, the solenoid valve 9 will open, controlling the water flow into the user's water supply pipe 4. In this way, the connecting pipe 11 will not be overfilled with pressurized water, and the right-hand pump body 1, which is closest to the motor, can then pressurize the water supply to the lower-floor users. Example

[0022] Please refer to Figure 2 , Figure 2 The difference between the structure shown and that of Embodiment 1 is only in the increase of the number of pump bodies 1. At the same time, in all pairs of adjacent pump bodies 1, the solenoid valve 9 at the lower end of the right pump body 1 is connected to the water inlet pipe 7 at the upper end of the left pump body 1 through the connecting pipe 11. Only the water outlet pipe 8 at the lower end of the leftmost pump body 1, which is farthest from the motor, is not equipped with a solenoid valve 9. All other water outlet pipes 8 at the lower end of the pump body 1 are equipped with solenoid valves 9.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various changes and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
