[0003] In the prior art, when testing some centrifugal pumps with a net positive suction head value less than 1m, ordinary valves cannot meet the test accuracy requirements, because the sealing performance of ordinary valves is not good enough. When the inlet pipeline pressure is less than atmospheric pressure, gas will be sucked into the pipeline through the valve packing seal, resulting in inaccurate test results. In addition, the traditional water seal valve often has a flushing pipe at the valve packing seal, which isolates the pipeline system from the atmosphere by continuously introducing cooling water. However, this structure not only requires on-site fabrication of cooling water inlet and outlet pipelines, but also requires a small flow rate water supply pump. Since the pump factory is usually a temporary test circuit with a short test period, the test circuit is dismantled after the test is completed. Therefore, it is particularly troublesome to provide a cooling water pipe for the valve, and it also affects the test progress.

[0034] like Figures 1 to 4 As shown, this utility model provides an integrated water seal valve water supply device, including an integrated water seal valve water supply device valve body 1. A connecting pipe 2 is fixedly connected through the middle of the integrated water seal valve water supply device valve body 1, and a plug 13 is fixedly connected through one side of the interior of the integrated water seal valve water supply device valve body 1. Packing blocks 14 are fixedly connected to both sides of the interior of the integrated water seal valve water supply device valve body 1, and one end of each packing block 14 is connected to one side of the corresponding connecting pipe 2. One side of the right packing block 14 is fixedly connected to one end of a pipe connector 15, and the other end of the pipe connector 15 is fixedly connected to one flange of a connecting pipe 16. The other end of the connecting pipe 16 is fixedly connected to the bottom of a water tank 17 made of transparent material. The top height of the water tank 17 is higher than the top height of the packing block 14. The water tank 17 is an interchangeable structure.

[0035] By using the integrated water seal valve supply device 1, this device eliminates the need for traditional water supply inlet and outlet pipelines and water pumps. When the device is working, it stores an appropriate amount of liquid in the water tank 17 to ensure that the packing block 14 is always submerged in water. This perfectly isolates the packing seal from the atmosphere. During a water pump cavitation test, if a negative pressure forms in the pipeline, the water in the water tank 17 automatically supplies water to the packing block 14 seal by gravity to compensate. Since the cavitation test time is very short, the water in the tank is sufficient to compensate for the valve's water supply, thus achieving the valve's water seal effect very simply.

[0036] like Figures 1 to 4 As shown, both ends of the connecting pipe 2 are welded with connection ports 3, and a hollow mounting cover 4 is fixedly connected to the outer wall of the end of the connection port 3 away from the connecting pipe 2. A flexible material connecting strip 5 is fixedly connected to the end of the mounting cover 4 away from the connection port 3, and one end of the connecting strip 5 is fixedly connected to one end of the elastic sealing strip 6. A ring-shaped stabilizing balloon 7 is fixedly connected to the inner wall of the mounting cover 4, and silicone protrusions 8 for contacting the outer wall of the connecting pipe are fixedly connected at equal intervals on the outer wall of the stabilizing balloon 7 near the center point of the mounting cover 4. Movable cavities 9 are fixedly connected at equal intervals on the inner wall of the maximum diameter of the stabilizing balloon 7, and connecting springs 10 are fixedly connected at equal intervals on one end of the inner wall of the movable cavity 9. A damping block 12 is fixedly connected to one end of the connecting spring 10 through an extension plate 11, and the damping block 12 is a semi-cylindrical structure.

[0037] By using the connection port 3, during testing and other operations, the connection port 3 can be connected to the output, input, or detection end of the connecting pipe. After the connecting pipe is connected, the stabilizing balloon 7, together with the silicone protrusion 8, wraps around its outer wall, making the connecting pipe more stable and preventing sealing problems at the connection. Furthermore, the damping block 12, during use, is driven by the potential energy released by the connecting spring 10 from the extension plate 11, which drives the damping block 12 to move towards the center point of the stabilizing balloon 7. This further enhances the wrapping force of the stabilizing balloon 7 and the silicone protrusion 8 on the connecting pipe.

[0038] like Figure 1 As shown, a liquid level monitoring sensor 18 is fixedly connected to the top of the water tank 17. A liquid replenishment port 19 is fixedly connected through the middle of the top of the water tank 17. A sealing cap 20 is snapped onto the top of the liquid replenishment port 19, and a transmission pipe 21 is fixedly connected through the flange at the top of the sealing cap 20. With the liquid level monitoring sensor 18, the liquid level in the water tank 17 can be monitored in real time during use. When the liquid level in the water tank 17 is too low, the operator can replenish the liquid in time. At the same time, automatic liquid replenishment can be achieved through the transmission pipe 21, making the device more convenient to use.

[0039] The principle and process of this utility model:

[0040] First, before the test, pour an appropriate amount of clean water into the water tank 17 and connect the connection port 3 to the output, input or detection end of the connecting pipe.

[0041] Secondly, after the connecting pipe is connected, the stabilizing balloon 7 and the silicone protrusion 8 are wrapped around its outer wall. The damping block 12 is driven to move towards the center point of the stabilizing balloon 7 by the potential energy released by the connecting spring 10 through the extension plate 11. This further improves the wrapping force of the stabilizing balloon 7 and the silicone protrusion 8 on the connecting pipe.

[0042] Subsequently, when the water pump cavitation test is carried out, once the pipeline forms a negative pressure, the water in the water tank 17 will automatically supply water to the packing block 14 seal by gravity to compensate for the negative pressure.

[0043] Finally, by using the liquid level monitoring sensor 18, the liquid level in the water tank 17 can be monitored in real time during use. When the liquid level in the water tank 17 is too low, the operator can replenish the liquid in time. At the same time, the transmission pipe 21 can automatically replenish the liquid. In this way, the integrated water seal valve water supply device is completed.
