Description

Technical Field

[0001] The utility model relates to the technical field of water replenishment devices, and specifically to an intelligent water replenishment device for a heat exchange unit. Background Art

[0002] The heating water of the heating heat exchanger unit is circulated in the system. In order to avoid the system pressure reduction caused by insufficient water in the system, a water replenishment system needs to be set up to automatically replenish the water in the heating water circulation system. The water replenishment system can automatically detect water shortage through a water level sensor. The water level sensor is a device that can sense the water level and convert it into an electrical signal. It is usually installed at the bottom or side wall of the water tank. When the water level is lower than the set minimum water level line, the water level sensor will send a signal to notify the water replenishment system that water replenishment is needed.

[0003] Existing devices have some disadvantages during use. For example, the reliability of the liquid level sensor may be seriously affected after long-term use. The aging of the material and the change of the electrical performance may cause the sensor to fail or malfunction frequently, which will lead to interruptions and delays in the production process and increase the cost of maintenance and replacement of the sensor. In addition, the liquid level sensor will be affected by attachments and dirt during use. Utility Model Content

[0006] In the above scheme, the water replenishment tank is the main part of the water replenishment device, which is used to store and supply replenishment water. The sleeve pipe is used to guide the water flow. The water inlet pipe guides the water flow into the sleeve pipe and then into the water replenishment tank through the water guide pipe. The length of the water guide pipe is adjustable to avoid excessive noise from falling water. The liquid level of the water replenishment tank can be controlled by the set water control mechanism, thereby realizing intelligent water replenishment.

[0026] like Figure 1 and Figure 2As shown, the utility model provides a technical solution: an intelligent water replenishment device for a heat exchanger unit, comprising a water replenishment tank 10, a sleeve tube 11 is fixedly connected to one side of the top of the water replenishment tank 10, a water inlet pipe 12 is transversely fixed to the inner side of the sleeve tube 11, a water inlet end of the water inlet pipe 12 is connected to an external water source, one end of the water inlet pipe 12 extends to the outside of the sleeve tube 11, a water control mechanism for controlling the water flow is arranged at the end of the sleeve tube 11 located inside the water replenishment tank 10, a water guide pipe 13 is fixedly connected to the lower end surface of the sleeve tube 11, the water inlet end of the water guide pipe 13 is communicated with the sleeve tube 11, a water replenishment pipe 14 is fixedly connected to one side of the bottom of the water replenishment tank 10, and the water inlet end of the water replenishment pipe 14 is connected to the outer side of the sleeve tube 11. It is connected to the water supply tank 10, and the water outlet end of the water supply pipe 14 is connected to the pipeline of the external heat exchanger unit. During specific use, the water supply tank 10 is the main part of the water supply device, which is used to store and supply water supply. The sleeve pipe 11 is used to guide the water flow. The water inlet pipe 12 guides the water flow into the sleeve pipe 11 and then guides it into the water supply tank 10 through the water guide pipe 13. The length of the water guide pipe 13 is adjustable to avoid excessive sound of falling water. The liquid level of the water supply tank 10 can be controlled by the set water control mechanism, thereby realizing intelligent water supply, and the water is transported to the external heat exchanger unit through the set water supply pipe 14, thereby realizing the water supply operation of the heat exchanger unit.

[0027] As an implementation method in this embodiment, Figure 2 , Figure 3 and Figure 4As shown, the water control mechanism includes a water inlet valve 20 arranged on the end of the sleeve tube 11, and the water inlet valve 20 is made of elastic rubber material. The water inlet valve 20 adopts elastic rubber material to facilitate deformation. A pin 21 is arranged on one side of the water inlet valve 20, and a fixer 22 is slidably sleeved on the outer side of the pin 21. The end of the sleeve tube 11 located on the inner side of the water replenishment tank 10 is threadedly connected with a sealing cover 23, and a connecting seat 24 is fixedly connected to the outer side wall of the pin 21 and the fixer 22. A float arm 25 is rotatably connected to the connecting seat 24. A fixing plate 26 is fixedly connected to the upper end surface of the float arm 25, and a top rod 27 is threadedly connected to the center of the fixing plate 26. The bottom end of the float arm 25 is fixedly connected to a connecting rod 28, and a hollow float 29 is fixedly connected to the connecting rod 28. During specific use, the hollow float 29 is filled with air. The interior of 29 is filled with air, so that the hollow float 29 will float on the liquid surface, and the hollow float 29 will rise or fall according to the liquid level in the water replenishment tank 10. When the water level in the water replenishment tank 10 is low, the float arm 25 is driven to move by the hollow float 29, and the push rod 27 connected to the float arm 25 will not apply pressure to the pin 21, so that the push rod 27 will not press the center of the water inlet valve 20, and the water inlet valve 20 will not block the water outlet of the water inlet pipe 12. When the water level of the water replenishment tank 10 is high, the push rod 27 connected to the float arm 25 applies pressure to the pin 21, so that the push rod 27 presses the center of the water inlet valve 20, and the water inlet valve 20 will block the water outlet of the water inlet pipe 12. The sealing cover 23 is set to fix the fixture 22, and the fixture 22 squeezes the water inlet valve 20 to prevent the water inlet valve 20 from moving or falling off.

[0028] As an implementation method in this embodiment, Figure 1 As shown, a solenoid valve 141 is fixedly connected to the water replenishment pipe 14, and the solenoid valve 141 is electrically connected to the external main control system. When the external main control system receives a signal that water replenishment is required, it will electrically control the solenoid valve 141 to open, so that the water replenishment pipe 14 transports water to the external heat exchanger unit, thereby realizing the water replenishment operation of the heat exchanger unit.

[0029] As an implementation method in this embodiment, Figure 4 As shown, a plurality of convex strips 231 of auxiliary knobs are fixedly connected in an annular array on the outer wall of the sealing cover 23. The convex strips 231 increase the friction between the sealing cover 23 and the palm, making the sealing cover 23 easy to manually disassemble and assemble.

[0030] Working principle: When in use, the hollow float 29 rises or falls according to the liquid level in the water replenishment tank 10. When the water level in the water replenishment tank 10 is low, the float arm 25 is driven to move by the hollow float 29. The push rod 27 connected to the float arm 25 will not apply pressure to the pin 21, so that the push rod 27 will not press the center of the water inlet valve 20, and the water inlet valve 20 will not block the water outlet of the water inlet pipe 12. When the water level in the water replenishment tank 10 is high, the push rod 27 connected to the float arm 25 applies pressure to the pin 21, so that the push rod 27 presses the center of the water inlet valve 20, and the water inlet valve 20 will block the water outlet of the water inlet pipe 12. The sealing cover 23 is used to fix the fixture 22, and the fixture 22 squeezes the water inlet valve 20 to prevent the water inlet valve 20 from moving or falling off.

[0031] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
