[0002] Currently, in many industries such as chemical engineering, energy, and electric power, a water pump circulation system is required to cool the medium. The commonly used solution is a water pump negative pressure drainage system, which uses a drainage tank to form a vacuum to continuously suck water in the storage pool, enabling the circulation pump to continuously operate for heat dissipation. Compared with the self-priming pump solution, it has low power consumption, high reliability, and convenient maintenance.

[0003] However, in the operation process of this water pump negative pressure drainage system solution, the air pressure in the drainage tank is likely to increase due to high temperature, resulting in an increase in the pressure of the gas cavity above after the water vaporizes, causing the circulation water pump to pump out the liquid inside the drainage tank, and the liquid inside the drainage tank cannot be drained and replenished in time; and during the operation process, air is also easily sucked into the circulation pump, resulting in an air binding phenomenon. Therefore, it is necessary to manually replenish water inside the drainage tank regularly and manually exhaust the circulation water pump, with low automation; and the connections of multiple structures are all connected through the connecting flanges of the flange plates, and the flange plates are connected through multiple external fastening bolts and nuts for combined connection, resulting in inconvenience during installation, combination, and disassembly, affecting the installation and combination efficiency. Therefore, an automatic water replenishment device for a water pump drainage tank is proposed. Summary of the Utility Model

[0008] Preferably, one end of the water replenishing pipe is communicated with the inner cavity of the drainage tank, and the connecting hoses at both ends of the circulating water pump are respectively communicated with one end of the one-way check valve and the Y-shaped filter.

When a negative pressure is generated inside the drainage tank 1, the liquid inside the reservoir 2 can pass through the coarse filter 7 and then enter the inside of the drainage tank 1 through the inlet pipe 6 to achieve the function of automatic water replenishment;

[0026] One side of the drainage tank 1 is connected with a Y-shaped filter 8. On one side of the Y-shaped filter 8, a circulating water pump 9 is arranged. One side of the water storage tank 3 is connected with a butterfly valve 10. One end of the butterfly valve 10 is connected with a one-way check valve 11.

Installation and use can be completed without external bolts and nuts.

[0028] As shown in the appendix Figure 1 、 2 As shown, one end of the water replenishing pipe 13 is communicated with the inner cavity of the drainage tank 1. The connecting hoses 12 at both ends of the circulating water pump 9 are respectively communicated with one end of the one-way check valve 11 and the Y-shaped filter 8. When the pressure in the water storage tank 3 increases, part of the liquid can flow back into the inside of the drainage tank 1 through the water replenishing pipe 13 to replenish water to the drainage tank 1, realizing the function of water replenishment. And by starting the circulating water pump 9, the liquid inside the drainage tank 1 filtered by the Y-shaped filter 8 can be input into the water storage tank 3 through the one-way check valve 11 and the butterfly valve 10.

[0029] As shown in the appendixFigures 4-6 As shown in the figure, the quick-connect and quick-disconnect sealing mechanism includes a sealing groove 17 opened on one side of the first connecting flange 15. One side of the second connecting flange 16 is fixedly connected with an extrusion ring 18.

[0034] When the circulating water pump 9 inputs the liquid inside the drainage tank 1 into the middle of the water storage tank 3, the liquid entering the inside of the circulating water pump 9 can be filtered by the Y-shaped filter 8. At this time, a pressure difference is generated inside the drainage tank 1. Through the guidance and filtration of the inlet pipe 6 and the coarse filter 7, the liquid inside the reservoir 2 is supplemented into the inside of the drainage tank 1, realizing the function of automatic water replenishment;

[0035] Through the combination of multiple butterfly valves 10, the circulating water pump 9 and the drainage tank 1 set, multi-pump parallel connection can be facilitated, so that different combination branches can be arbitrarily selected for use, which is convenient for maintenance and use;

[0036] During the operation of the device, when the air pressure inside the drainage tank 1 increases due to high temperature and the liquid inside the reservoir 2 cannot be replenished into the drainage tank 1 in time, the water replenishing ball valve 14 can be opened to allow the liquid inside the water storage tank 3 to flow into the drainage tank 1 to achieve the function of water replenishment, thereby realizing automatic water replenishment;

[0037] When connecting the first connecting flange 15 and the second connecting flange 16, only need to insert the extrusion ring 18 into the sealing groove 17 to extrude the sealing ring 19, and make the limiting groove 21 correspond to the clamping groove 20. At this time, rotate the screw rod 22 to make the screw rod 22 snap into the clamping groove 20 and rotate the nut 23 at one end of the screw rod 22 to extrude the second connecting flange 16 to complete the fixation. It can be connected and used without external bolts and nuts, improving the use effect.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
