Technical Field

[0001] This utility model relates to the field of water replenishment technology for thermal systems, specifically a water replenishment device for thermal systems. Background Technology

[0002] Water replenishment devices are crucial during power plant operation. Timely water replenishment is essential for maintaining the balance of the steam-water system of the unit, thus ensuring the stability of the thermal system during operation.

[0003] In existing technology, the water supply device is connected to the main pipeline of the heating system to deliver water into the interior of the heating system, which enables the heating system to work stably with the support of the water supply device.

[0004] However, in actual use, the heating device needs to be replenished with salt water. When making the salt water, impurities from the salt particles are mixed into the water and enter the heating device along with the water. Long-term replenishment of water can damage the heating device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a water replenishment device for a thermal system. This solves the problem that, in actual use, the thermal system needs to be replenished with salt water. However, during the preparation of the salt water, impurities from the salt particles are mixed into the water and enter the thermal system along with the water. Prolonged water replenishment can lead to damage to the thermal system.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water replenishment device for a thermal system, comprising a treatment tank, one end of which is connected to a valve, and the other side of which is connected to a tubular flow meter. A screen is installed inside the treatment tank, and valve stems are installed on the outer wall of the screen. Two valve stems are provided. A safety chamber is formed at the bottom of the inner wall of the treatment tank. The valve stems are movably connected to the upper part of the inner wall of the treatment tank and the inner wall of the safety chamber, respectively. A sealing gasket is installed between the valve stems and the treatment tank. A replacement device is installed on the outer wall of the valve stems.

[0007] Preferably, the replacement device includes a fixed frame, a locking block is fixedly connected to the outer wall of the fixed frame, the locking block is slidably engaged with a locking groove, the locking groove is opened in the inner wall of the valve column, and replacement chambers are provided on both sides of the valve column, the replacement chambers are opened in the outer wall of the processing box.

[0008] Preferably, a drive rod is fixedly connected between the two valve stems, the outer wall of the drive rod is rotatably connected to the inner wall of the processing box through a sealed bearing, and a servo motor is fixedly connected to one end of the drive rod extending to the top of the processing box, the outer wall of the servo motor being fixedly connected to the top of the processing box.

[0009] Preferably, a connecting pipe is fixedly connected to the lower outer wall of the treatment box, the connecting pipe is connected to the replacement chamber, and a one-way valve is installed at the end of the connecting pipe away from the treatment box. The one-way valve is connected to a tubular flow meter through a pipe.

[0010] Preferably, a rubber pad is fixedly connected to the outer wall of the fixed frame, and the outer wall of the rubber pad abuts against the outer wall of the screen. Beneficial effects

[0011] This invention provides a water replenishment device for a thermal system. It offers the following advantages: Through the cooperation of a treatment tank, a screen, and a valve column, this water replenishment device removes impurities from the brine as the water passes through the treatment tank and the screen acts on it. This prevents impurities from entering the thermal system and solves the problem of needing to use brine to replenish the thermal system, where impurities from the salt particles are mixed into the water during brine preparation and enter the thermal system with the water, potentially causing damage to the thermal system with prolonged water replenishment.

[0012] By using a connecting pipe, a one-way valve, and a safety chamber, when the screen becomes clogged, the two valve stems can be rotated to allow the valve stem and screen in the safety chamber to filter the water, while the screen in the upper valve stem can be replaced. In this way, while replacing the screen, the water can still enter the heating device through the safety chamber and connecting pipe, and the one-way valve can ensure that the water does not flow back. This solves the problem that existing water replenishment devices require shutting down the pipeline for replacement when they become clogged, which leads to reduced work efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In actual use, the heating device needs to be replenished with brine. However, when making brine, impurities from the salt particles are mixed into the water and enter the heating device along with the water. Over time, this replenishment can damage the heating device.

[0017] In view of this, the present invention provides a water replenishment device for a thermal system, which solves the problem that when the thermal system needs to be replenished with salt water in actual use, impurities from the salt particles will be mixed into the water during the preparation of the salt water and enter the thermal system with the water. Long-term water replenishment will cause damage to the thermal system.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process.

[0019] Example 1: By Figure 1-5 It is known that a water replenishment device for a thermal system includes a treatment tank 1. One end of the treatment tank 1 is connected to a valve 3, and the other side of the treatment tank 1 is connected to a tubular flow meter 4. A screen 9 is installed inside the treatment tank 1, and a valve column 8 is installed on the outer wall of the screen 9. There are two valve columns 8. A safety chamber 5 is opened at the bottom of the inner wall of the treatment tank 1. The valve columns 8 are respectively movably connected to the upper part of the inner wall of the treatment tank 1 and the inner wall of the safety chamber 5. A sealing gasket 12 is installed between the valve column 8 and the treatment tank 1. A replacement device is installed on the outer wall of the valve column 8. In the specific implementation process, it is worth noting that two cavities are opened in the inner wall of the treatment tank 1. The upper cavity is the main pipe, through which water mainly flows when replenishing. The safety cavity 5 is connected to the main pipe, but with the cooperation of the two valves 8, the main pipe and the safety cavity 5 will open and close separately. When the opening on the side of the upper valve 8 is connected to the main pipe, the lower valve 8 will close the safety cavity 5. In this way, when water flows through the main pipe, the water in the safety cavity 5 will not flow, thus achieving diversion. When replenishing water to the heating device, the tubular flow meter 4 is connected to the heating device to detect the amount of replenished water. At the same time, the side of the treatment tank 1 where the valve 3 is installed is connected to the water supply device. In this way, when the water supply is stopped, the valve 3 will close the pipe, thus stopping the water supply. The tubular flow meter 4 is installed in the outlet direction of the treatment tank 1 to measure the filtered water. The specific model of the flow meter is not limited, as long as it meets the actual use. The model of the valve 3 is also not limited. The appropriate screen size 9 should be selected based on actual usage conditions to facilitate brine filtration. A sealing gasket 12 is installed between the valve column 8 and the treatment box 1 to prevent leakage and ensure efficient water delivery. When the screen 9 becomes clogged, a replacement device is used to replace it, ensuring stable filtration. Two identical valve columns 8, one above the other, are positioned inside the treatment box 1, with through holes on both sides to accommodate the screen 9. When placed inside the treatment box 1, the through holes are crisscrossed. When replacing the screen 9, rotating one valve column 8 90 degrees will simultaneously rotate the other 90 degrees. This allows the upper valve column 8 to close the main pipe inside the treatment box 1, while the lower valve column 8 opens the safety chamber 5, allowing water to flow through the safety chamber 5 and into the heating device, ensuring simultaneous filtration when replacing the screen 9. Furthermore, the replacement device includes a fixed frame 13, a locking block 15 is fixedly connected to the outer wall of the fixed frame 13, the locking block 15 is slidably engaged with a locking groove 14, the locking groove 14 is opened on the inner wall of the valve column 8, and replacement chambers 11 are provided on both sides of the valve column 8, the replacement chambers 11 are opened on the outer wall of the processing box 1. In the specific implementation process, it is worth noting that the shape of the fixing frame 13 is the same as the shape of the through hole opened on the valve column 8, which makes it convenient to fix the screen 9. In addition, the slot 14 opened on the inner wall of the valve column 8 allows the locking block 15 to be inserted inside. When the fixing frame 13 is inserted into the valve column 8, the locking block 15 will be inserted into the slot 14. When it is fully inserted into the slot 14, the fixing frame 13 is rotated and moved so that the locking block 15 is pressed against the inside of the slot 14. In this way, the fixing frame 13 is fixed in the through hole in the valve column 8, and the screen 9 is fixed inside the valve column 8. At the same time, a replacement cavity 11 is opened on the side of the processing box 1. The screen 9 inside can be replaced by using the replacement cavity 11, which ensures that it is convenient to replace. Furthermore, a drive rod 10 is fixedly connected between the two valve columns 8. The outer wall of the drive rod 10 is rotatably connected to the inner wall of the processing box 1 through a sealed bearing. A servo motor 2 is fixedly connected to one end of the drive rod 10 that extends to the top of the processing box 1. The outer wall of the servo motor 2 is fixedly connected to the top of the processing box 1. In the specific implementation process, it is worth noting that the two valve stems 8 are connected together by the drive rod 10. This ensures that the two valve stems 8 can rotate synchronously, and the rotation of the two valve stems 8 is stable under the drive of the servo motor 2. It is also worth mentioning that the operator only needs to control the servo motor 2 to drive the valve stems 8 to rotate 90 degrees. The model of the servo motor 2 is not limited, as long as it meets the actual use.

[0020] Example 2: From Figure 1-5 It can be seen that a connecting pipe 6 is fixedly connected to the lower outer wall of the treatment box 1. The connecting pipe 6 is connected to the replacement chamber 11. A one-way valve 7 is installed at the end of the connecting pipe 6 away from the treatment box 1. The one-way valve 7 is connected to the tubular flow meter 4 through a pipe. In the specific implementation process, it is worth noting that the one-way valve 7 can ensure that the water in the main pipeline will not flow back into the safety chamber 5 in the treatment tank 1 through the connecting pipe 6. At the same time, the water flowing out of the connecting pipe 6 will also enter the water flow in the heating device through the tubular flow meter 4 for statistical analysis, ensuring that the dosage of water entering the heating device is stable. In this way, when the screen 9 in the main pipeline is blocked and needs to be replaced, the water will enter the heating device through the safety chamber 5 and the connecting pipe 6, thereby making the overall practicality of the device higher. Furthermore, a rubber pad 16 is fixedly connected to the outer wall of the fixed frame 13, and the outer wall of the rubber pad 16 abuts against the outer wall of the screen 9. In the specific implementation process, it is worth noting that the material of the rubber pad 16 is rubber. When fixing the screen 9, the fixing frame 13 will squeeze the rubber pad 16, and the rubber pad 16 will seal the gap between the screen 9 and the fixing frame 13 under its own elasticity, so as to avoid leakage when water flows through, which would affect the filtration effect.
