Technical Field

[0001] This application relates to the field of energy-saving and environmental protection equipment for cooling water circulation, and particularly to a cooling water energy-saving circulation device. Background Art

[0002] Cooling water energy-saving circulation devices are widely used in industrial cooling, air conditioning systems and other fields, aiming to improve the efficiency of the cooling system, reduce energy consumption and water resource waste. With the acceleration of the industrialization process, the demand for high-efficiency cooling equipment is increasing day by day. Although traditional cooling systems can meet basic cooling needs, they have problems such as high energy consumption and low water resource utilization rate in actual applications, seriously affecting production efficiency and environmental protection. To address the above problems, existing technical solutions usually adopt various methods to optimize the performance of the cooling system. Among them, common means include using efficient heat exchangers, adjusting the water flow rate, improving pipeline design, etc. For example, by increasing the heat transfer area and improving the fluid flow characteristics, the heat transfer efficiency can be effectively improved; by reasonably arranging the pipelines, reducing elbows and resistance points, and reducing the water pressure loss, energy can be further saved; in addition, the heat exchanger and pipelines can be cleaned regularly to keep them in good working condition and extend their service life. However, these conventional means still have certain limitations in actual applications. Especially in the case where the cooling temperature needs to be precisely controlled, traditional cooling systems often have difficulty achieving precise energy management, easily resulting in excessive or insufficient water supply, thereby affecting the working stability and efficiency of the cooled mechanism. Summary of the Invention

[0003] In order to precisely control the water supply to control the cooling temperature, this application provides a cooling water energy-saving circulation device.

The energy-saving valve is used to prevent excessive water supply.

[0006] By adopting the above technical solution, the water storage tank is installed on the bracket, and the water supply pipe is connected to the water storage tank through the water supply pump, ensuring the stable water supply of the system; the heat exchanger is installed on the bracket and connected to the water storage tank, and the return water pipe is connected to the heat exchanger through the return water pump, realizing an efficient heat exchange process; a water-saving pipe is installed on the water supply pipe through an energy-saving valve, and the other end of the water-saving pipe is connected to the heat exchanger. The energy-saving valve is used to avoid excessive water supply, thereby preventing the increase in energy consumption and water resource waste caused by overcooling.

[0007] In a specific feasible embodiment, the energy-saving valve includes a valve body, a valve core, a valve seat and a limit seat. One end of the valve body is provided with a water inlet, and the valve body is provided with a first water outlet and a second water outlet. The first water outlet is connected to the water outlet pipe and thus connected to the external water supply device in need. The second water outlet is connected to the return water pipe through the heat exchanger. The valve seat is installed in the valve body below the second water outlet, the limit seat is installed in the valve body above the second water outlet, the valve core is installed between the valve seat and the limit seat. The valve core is provided with a first water passing hole and a second water passing hole. The limit seat is provided with a limit seat through hole. One end of the water inlet of the first water passing hole faces the water inlet, and the valve seat can block the first water passing hole.

One end of the water inlet of the second water passing hole faces the water inlet, and one end of the water outlet of the second water passing hole can be connected to the second water outlet hole, and the side wall of the valve body can block one end of the water outlet of the second water passing hole. An electromagnetic coil is arranged in the valve seat.

[0008] By adopting the above technical solution, the energy-saving valve can accurately control the water flow distribution, avoid excessive water supply, and thus effectively save energy and water resources. Specifically, the first water passing hole and the second water passing hole in the valve body respectively realize the water flow regulation of different paths. Among them, the first water passing hole ensures the smooth entry of water into the heat exchanger through connection with the limit seat through hole, while the second water passing hole diverts the excess water back to the return water pipe through connection with the second water outlet. At the same time, the blocking effects of the valve seat and the side wall of the valve body on the corresponding water passing holes ensure the precise control of the water flow. The addition of the electromagnetic coil further improves the automation degree of the valve, enabling it to quickly respond when needed and adjust the water flow state, thereby enhancing the efficiency of the entire cooling system.

[0009] In a specific feasible embodiment, a telescopic pipe is further included. Both ends of the telescopic pipe are respectively connected to the limit seat and the valve core, and the limit seat through hole opened on the limit seat and the first water passing hole opened on the valve core are hermetically connected through the telescopic pipe.

[0012] By adopting the above technical solution, the setting of the return spring can ensure that the valve core automatically resets to the initial position when the electromagnetic coil is not powered on, ensuring the correct switching of the water flow path, and improving the stability and reliability of the system. At the same time, the return spring can also reduce the impact force during the movement of the valve core, extending the service life of the energy-saving valve.

[0016] By adopting the above technical solution, the integrated control module can achieve precise control of the electromagnetic coil, and then adjust the position of the valve core, accurately controlling the opening and closing of the first water through hole and the second water through hole. This not only improves the automation degree of the system, but also ensures the reasonable distribution of water flow, further enhancing the cooling efficiency and energy-saving effect.

[0017] In a specific feasible implementation, it further includes a flow sensor, which is installed at one end of the valve body adjacent to the second water outlet. The flow sensor is used to detect the water output at the second water outlet, and the flow sensor is electrically connected to the integrated control module.

[0018] By adopting the above technical solution, the flow sensor can monitor the water output at the second water outlet in real time and transmit the data to the integrated control module. The integrated control module adjusts the working state of the electromagnetic coil according to the data provided by the flow sensor, and then accurately controls the position of the valve core and the opening degree of the water passage hole to ensure that the water flow is stable and meets the requirements. This can effectively avoid the occurrence of excessive or insufficient water supply, further improve the energy efficiency ratio and stability of the system, and reduce energy waste and water resource consumption.
