[0013] The technical effects and advantages of the present utility model:

[0014] 1. By arranging a pressure boosting pipe between the booster pump and the pressure boosting tank, both the booster pump and the pressure boosting tank can boost the water in the pressure boosting pipe. By arranging an extension pipe between the booster pump and the pressure boosting tank, the extension pipe can realize the direct connection between the booster pump and the pressure boosting tank, so that while the booster pump pressurizes the pressure boosting pipe, it can also pressurize the pressure boosting tank to maximize the utilization of the output pressure of the booster pump.

[0015] 2. The utility model realizes the automatic control of the output path of the booster pump by setting a fixed sleeve at the bottom end of the connecting sleeve. The bottom end of the fixed sleeve is connected to the water guide pipe through a pressure detection pipe. The water in the pipeline can act on the piston head in the fixed sleeve, causing the piston head to drive the movable plug to move. When the movable plug is inserted into the connecting sleeve, it can control the on-off between the booster pump and the booster tank, so as to ensure the pressure balance in the pipeline while reducing the start-stop of the booster pump, thereby improving the service life of the device.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides a Figures 1-4 shown new non-negative pressure pipe network booster and flow stabilization water supply device, including a base 1, a plurality of booster pumps 2 are fixedly arranged on the upper surface of the base 1, a water inlet pipe 3 and a water outlet pipe 4 are respectively arranged on both sides of the booster pump 2, and a booster tank 5 is arranged on one side of the water outlet pipe 4;

[0023] Specifically, a connecting pipe 6 is fixedly arranged between the water inlet pipe 3 and the input end of the booster pump 2, a boosting pipe 7 is fixedly arranged between the output end of the booster pump 2 and the water outlet pipe 4, and a water guiding pipe 8 is fixedly arranged between the water outlet pipe 4 and the booster tank 5. The water guiding pipe 8 can realize the pressurization of the water outlet pipe 4 by the booster tank 5;

[0024] More specifically, an extension pipe 9 is fixedly arranged in the middle of the booster tank 5. The top end of the extension pipe 9 is fixedly provided with a confluence pipe 10. A pressure control pipe 11 is fixedly arranged between the confluence pipe 10 and the booster tank 5. A pressure detection pipe 12 is fixedly arranged between the pressure control pipe 11 and the water guiding pipe 8. A control valve 13 is fixedly arranged in the middle of the pressure detection pipe 12. The top end of the pressure detection pipe 12 is fixedly provided with a fixing sleeve 14. The top end of the fixing sleeve 14 is fixedly provided with a connecting sleeve 15. And the connecting sleeve 15 is fixedly arranged between the pressure control pipe 11 and the booster tank 5;

[0025] Moreover, a through groove 16 is penetrated and opened in the middle of the connecting sleeve 15. A slot 17 is penetrated and opened in the middle of the inner side wall of the through groove 16. And the bottom end of the slot 17 extends to the top end of the fixing sleeve 14. A movable plug 18 is inserted in the slot 17. And the bottom end of the movable plug 18 extends into the fixing sleeve 14. A piston head 19 is fixedly arranged at the bottom end of the movable plug 18. A spring 20 is arranged between the piston head 19 and the inner wall of the top end of the fixing sleeve 14. The spring 20 can apply a downward acting force on the piston head 19 to ensure that the movable plug 18 can move downward when the water pressure in the pipeline is low, so as to ensure that the booster pump 2 can pressurize the booster tank 5;

[0026] In addition, an expansion tank 21 is fixedly arranged at one end of the upper surface of the base 1. And the expansion tank 21 is arranged between the water guiding pipe 8 and the booster tank 5.

[0027] The working principle of the utility model:

[0028] When this device is in use, the booster pump 2 can extract water from the water inlet pipe 3 through the connecting pipe 6 and transport the water to the booster pipe 7 to achieve the boosting of the water in the pipeline. During this process, the water in the booster tank 5 can be transported to the booster pipe 7 through the water guide pipe 8 to achieve the effect of auxiliary boosting. Moreover, the water in the water guide pipe 8 can enter the fixed sleeve 14 through the pressure detection pipe 12 and squeeze the piston head 19 in the fixed sleeve 14, causing the piston head 19 to drive the movable plug 18 to move upward. At this time, the movable plug 18 is inserted into the slot 17 and blocks the through groove 16 to achieve the control of the on-off of the pressure control pipe 11. When the internal pressure of the booster tank 5 is relatively large, the movable plug 18 is inserted into the slot 17 under the action of pressure. At this time, the booster pump 2 stops boosting the booster tank 5. When the internal pressure of the booster tank 5 is relatively small, the movable plug 18 moves downward under the action of the spring 20. At this time, the booster pump 2 can pressurize the booster tank 5 through the pressure control pipe 11 to achieve the effect of controlling the pipeline pressure.
