Description

Variable frequency water supply equipment time-segment flow regulation device Technical Field

[0001] This utility model relates to the field of water supply equipment technology, and in particular to a time-segmented flow regulation device for variable frequency water supply equipment. Background Technology

[0002] In existing water supply systems, variable frequency water supply equipment is a key component in ensuring a stable supply of water for residential use and industrial production. However, users' water demand varies significantly at different times of day; for example, water consumption at night is significantly lower than during the day. Traditional variable frequency water supply equipment often struggles to accurately and flexibly adjust water flow according to these time-of-day changes.

[0003] Currently, although some water supply equipment has certain flow regulation functions, the regulation method is relatively simple, usually achieving flow control by manually adjusting the valve opening. This method is not only cumbersome to operate and requires frequent manual intervention, but also makes it difficult to achieve precise flow regulation, failing to meet the refined needs for water flow at different times. In addition, manually adjusting the valve opening cannot be adjusted in real time according to the actual water usage, which can easily lead to insufficient or excessive water supply, resulting in water waste or failure to meet the normal water needs of users.

[0004] In addition, some existing flow control devices have complex structures, low reliability, and are prone to failure, which increases the maintenance cost and downtime of the equipment.

[0005] Moreover, these devices lack a visual display of the adjustment status, making it difficult for operators to accurately grasp the position of the regulating valve core and the flow adjustment situation, which further affects the accuracy and timeliness of flow adjustment.

[0006] To address the aforementioned issues, this utility model document proposes a time-segmented flow regulation device for variable frequency water supply equipment. Summary of the Invention

[0007] The purpose of this utility model is to solve the shortcomings of existing technologies, such as the single flow regulation method of traditional water supply equipment, inconvenience for precise real-time control, complex and prone to failure, and insufficient intuitive display of the regulation status. Therefore, a time-period flow regulation device for variable frequency water supply equipment is proposed.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The variable frequency water supply equipment includes a time-segmented flow control device, comprising:

[0010] The connecting part has a water supply channel inside, and inlet and outlet water pipes are fixedly installed on both sides of the connecting part. Both inlet and outlet water pipes are connected to the water supply channel to facilitate the connection between the connecting part and the external water supply pipe.

[0011] It also includes an adjustment component, which includes an adjustment valve core disposed in the connecting part. The adjustment valve core cooperates with the water supply channel to block the water supply channel accordingly. The adjustment component also includes an adjustment shaft rotatably mounted at the bottom of the connecting part. The outer wall of the adjustment shaft is provided with a continuous wave-shaped adjustment groove, which can drive the adjustment valve core to move up and down to adjust the flow rate of water passing through the water supply channel.

[0012] In one possible design, the regulating assembly further includes an regulating cavity formed within the connecting portion, the regulating cavity extending through the water supply channel, the regulating valve core slidingly sealingly engaging with the inner wall of the regulating cavity, a connecting rod fixedly mounted at the bottom of the regulating valve core, the bottom end of the connecting rod slidingly sealingly penetrating the bottom of the connecting portion, and a connecting column fixedly mounted near the bottom end of the connecting rod, the connecting column slidingly engaging with the inner wall of the regulating groove to achieve lifting and lowering control of the regulating valve core.

[0013] In one possible design, a limit strip is fixedly installed on the outer wall of the connecting rod, and the limit strip slides through the bottom of the connection to ensure that the regulating valve core and the connecting rod do not rotate during lifting.

[0014] In one possible design, the adjustment assembly further includes a mounting shell fixedly installed at the bottom of the connecting part. The mounting shell provides shielding protection for components located below the connecting part. A servo motor is installed inside the mounting shell and is fixedly connected to the bottom of the connecting part. A rotating shaft is fixedly installed at one end of the output shaft of the servo motor, and a second synchronous pulley is fixedly installed at one end of the rotating shaft. A first synchronous pulley is fixedly installed at the bottom end of the adjustment shaft. The second synchronous pulley and the first synchronous pulley are connected by a synchronous belt drive, thereby enabling precise control of the rotation angle of the adjustment shaft.

[0015] In one possible design, the regulating valve core has a water passage hole inside, which cooperates with two inlet and outlet water pipes to prevent the regulating valve core from completely blocking the water supply channel, thereby ensuring a basic water supply.

[0016] In one possible design, the mounting housing has grooves on both sides, and a fixing rod is fixedly inserted through the connecting rod near the bottom. Both ends of the fixing rod pass through the corresponding grooves and slide in cooperation with the inner walls of the corresponding grooves. Both ends of the fixing rod extend to the outside of the mounting housing and are fixedly mounted with indicator blocks. Two scales are fixedly mounted on the outer walls of both sides of the mounting housing. The scales cooperate with the two indicator blocks respectively to display the lifting distance of the regulating valve core.

[0017] In one possible design, a flow meter is fixedly embedded in the connection part, and the detection end of the flow meter extends into the water supply channel for detecting the flow rate of water passing through the water supply channel.

[0018] In this application, during use, the user can install the connecting part into the corresponding water supply system and ensure that the two inlet and outlet water pipes are tightly connected to the adjacent pipes. When the regulating valve core is at its lowest point, the water flowing into the water supply channel will pass through the water passage and through the regulating valve core, ensuring that the water supply system can maintain a basic water flow supply. A flow meter is installed in the water supply channel, allowing the user to collect and record the current water flow data. When the user needs to adjust the water flow, they only need to start the servo motor. The servo motor can drive the regulating shaft to rotate through the transmission of the second synchronous wheel and the first synchronous wheel, and the servo motor can precisely control the rotation angle of the regulating shaft. Since the connecting column slides in the regulating groove, as the regulating shaft rotates, the connecting column can move axially along the regulating shaft, and thus can be connected by the connecting rod. The system enables the regulating valve core to rise and fall. When the servo motor drives the regulating shaft to rotate 90 degrees, the regulating valve core can move from the lowest point to the highest point. At this time, the internal water flow space of the water supply channel reaches its maximum, ensuring the maximum flow rate of water in the water supply system. As the regulating shaft rotates continuously, the regulating valve core will move back to the lowest point, and then the above steps will be repeated. During use, the user can accurately adjust the height of the regulating valve core by precisely controlling and recording the rotation angle of the servo motor to meet the adjustment of the water supply flow. When the regulating valve core is rising and falling, the connecting rod can drive the indicator blocks on both sides to rise and fall synchronously through the fixed rod. By observing the scale position indicated by the indicator blocks on the external scale, the user can judge the specific height of the regulating valve core, which is convenient for the user to adjust and control the device from the outside.

[0019] Beneficial effects: In this utility model, the time-sharing flow adjustment device of the variable frequency water supply equipment uses a servo motor to precisely control the rotation angle of the adjustment shaft, thereby achieving accurate adjustment of the lifting height of the adjustment valve core. It can flexibly and accurately adjust the water flow according to the actual water demand at different times. Whether it is necessary to ensure the basic water supply or to achieve the maximum flow supply, it can be easily achieved, effectively meeting the differentiated water flow needs of users at different times.

[0020] In this utility model, the variable frequency water supply equipment time-period flow adjustment device has a water passage hole inside the regulating valve core. When the regulating valve core is at its lowest point, the water flow can pass through the water passage hole and through the regulating valve core, ensuring that the water supply system can maintain the most basic water supply. This design avoids the situation where the water supply is completely interrupted due to flow adjustment, and ensures the user's basic water needs.

[0021] In this utility model, the variable frequency water supply equipment time-segment flow adjustment device has a compact overall structure, with close cooperation between various components and a reasonable design of the adjustment assembly. Through the cooperation of the wave-shaped adjustment groove on the adjustment shaft and the connecting column, the smooth lifting and lowering of the adjustment valve core is achieved. At the same time, the setting of the limit bar ensures that the adjustment valve core and the connecting rod will not rotate during the lifting and lowering process, which improves the stability and reliability of the device, reduces the probability of failure, effectively reduces the downtime and maintenance frequency caused by failure, and thus reduces the maintenance cost of the equipment.

[0022] In this invention, the variable frequency water supply equipment time-segment flow regulating device has sliding grooves on both sides of the mounting shell. The connecting rod drives the indicator block to slide within the sliding grooves via the fixed rod. Combined with the scales on both sides of the connecting part, the operator can intuitively observe the lifting distance and current position of the regulating valve core, facilitating external adjustment and control of the device. This intuitive display method reduces the difficulty of operation and improves the accuracy and convenience of operation.

[0023] In this utility model, the time-period flow adjustment device of the variable frequency water supply equipment can precisely control the rotation angle of the adjustment shaft through a servo motor, which can flexibly and accurately adjust the water flow rate to meet the differentiated water demand at different times; the regulating valve core is equipped with a water passage hole to ensure the basic water supply and avoid water supply interruption; the device has a compact structure and reasonable design, the adjustment components are closely matched, the equipment has good stability and reliability, and the maintenance cost is reduced; the indicator block and scale work together to intuitively display the position and lifting distance of the regulating valve core, which improves the accuracy and convenience of operation and realizes efficient adjustment and control of water supply flow.

[0036] In this embodiment, a mounting shell 3 is fixedly installed at the bottom of the connecting part 1.

[0037] This application can be used in the field of water supply equipment technology, or in other fields applicable to this application.

[0038] Example 2: Referring to Figures 2, 3, and 5, an improvement is made to Example 1: a time-segment flow regulation device for variable frequency water supply equipment, which is applied to the field of water supply equipment technology;

[0039] In this embodiment, sliding grooves 20 are provided on both sides of the mounting shell 3. A fixing rod 12 is fixedly inserted through the connecting rod 8 near its bottom end. Both ends of the fixing rod 12 pass through the corresponding sliding grooves 20 and slide in cooperation with the inner walls of the corresponding sliding grooves 20. Both ends of the fixing rod 12 extend to the outside of the mounting shell 3 and are fixedly mounted with indicator blocks 13. Two scales 21 are fixedly mounted on the outer walls of both sides of the mounting shell 3, and the scales 21 cooperate with the two indicator blocks 13 respectively. The user can observe the scale indicated by the indicator blocks 13 from the outside, thereby judging the lifting distance of the regulating valve core 7, which facilitates accurate adjustment.

[0040] In this embodiment, a flow meter 6 is fixedly embedded in the connecting part 1, and the detection end of the flow meter 6 extends into the water supply channel 4, allowing the user to collect and record the current water supply flow rate. Combined with the precise control and recording of the rotation angle of the adjustment shaft by the servo motor, the user can analyze the flow adjustment situation at different times, providing a basis for further optimizing the operation of the water supply system.

[0041] However, as is well known to those skilled in the art, the working principles and wiring methods of the flow meter 6 and the servo motor 17 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0042] The working principle and usage process of this technical solution are as follows: During use, the user can install the connecting part 1 into the corresponding water supply system and ensure that the two inlet and outlet pipes 2 are tightly connected to the adjacent pipes. When the regulating valve core 7 is at its lowest point, the water flowing into the water supply channel 4 will pass through the water passage 9 and through the regulating valve core 7, ensuring that the water supply system can maintain a basic water flow supply. A flow meter 6 is installed in the water supply channel 4, allowing the user to collect and record the current water flow data. When the user needs to adjust the water flow, they only need to start the servo motor 17. The servo motor 17 can drive the regulating shaft 14 to rotate through the transmission of the second synchronous wheel 19 and the first synchronous wheel 16, and the servo motor 17 can precisely control the rotation angle of the regulating shaft 14. Since the connecting column 11 slides within the regulating groove 15, as the regulating shaft 14 rotates, the connecting column 11 can move axially along the regulating shaft 14. The regulating valve core 7 can then be raised and lowered via the connecting rod 8. When the servo motor 17 drives the regulating shaft 14 to rotate 90 degrees, the regulating valve core 7 can move from the lowest point to the highest point. At this time, the internal water flow space of the water supply channel 4 reaches its maximum, ensuring the maximum flow rate of water in the water supply system. As the regulating shaft 14 rotates continuously, the regulating valve core 7 will move back to the lowest point, and then the above steps will be repeated. During use, the user can accurately adjust the height of the regulating valve core 7 by precisely controlling and recording the rotation angle of the servo motor 17 to meet the adjustment of the water supply flow rate. When the regulating valve core 7 is raised and lowered, the connecting rod 8 can drive the indicator blocks 13 on both sides to rise and fall synchronously via the fixed rod 12. By observing the scale position indicated by the indicator block 13 on the external scale 21, the user can judge the specific height of the current regulating valve core 7, which is convenient for the user to adjust and control the device from the outside.

[0043] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
