Description

Technical Field

[0001] The utility model relates to the technical field of heating, in particular to a heating flow regulating device. Background Art

[0002] The heating courtyard pipe network design of most residential buildings adopts a different-path system. That is, the parallel loops where the heat users of different units are located are long or short, and the distance lengths are different, which is called "different-path". Different pipeline lengths mean different resistances along the way. The pipeline flow of the unit closer to the building entrance pipeline and the unit farther from the building entrance pipeline will be very different, and the heating temperature of users in different units will also be very different. To ensure balanced heating between units, the flow of each unit pipeline must be distributed and adjusted. For this work, it was generally adjusted through valves with different opening and closing degrees in the past, but this method has two disadvantages. First, the accuracy and timeliness of valve adjustment are difficult to meet the needs. The adjustment of the valve opening and closing degree is either large or small, and the adjustment effect can only be observed indirectly through the return water temperature. On the one hand, there is no intuitive data for reference, and on the other hand, the adjustment feedback is delayed, making it difficult to adjust flexibly; second, the valve adjustment is often changed by unauthorized personnel. Many unit pipelines in residential buildings in old communities do not have separate pipe wells, and the valves used for regulation are mostly installed in stairwells. The opening of the valves can be easily changed by users without permission, thus losing the proper regulation effect.

[0003] For example, the utility model patent with application number 202222252453.6, the technical solution adopted by the patent fully solves the above problems, but the technical solution of the patent still has certain defects. The flow control and adjustment device of the patent still adopts manual operation, and manual operation has the following disadvantages;

[0004] High maintenance costs: Manually controlled heating pipeline flow control devices require frequent manual operation and maintenance. This increases the maintenance workload and may lead to increased maintenance costs. Since the seals and intermediate parts inside the valve need to be replaced frequently, the maintenance workload is large, which consumes time and money. If maintenance is not timely, it may also cause poor valve operation or leakage, resulting in production losses.

[0005] Low control accuracy: Manual operation has errors and cannot guarantee accurate flow control. Especially in situations where high-precision control is required, manual operation is not stable and reliable enough. In addition, the scale lines of the manual valve are easily worn or unclear, which will affect the operator's judgment and lead to reduced control accuracy.

[0006] Low work efficiency: Manual operation requires manual work, and the operation cycle is long, which is difficult to adapt to the needs of high-speed flow control. Especially when adjusting the flow and controlling rapid flow changes, manual operation is difficult and will affect work efficiency.

[0007] Inconvenient operation: Manual operation requires professionals, and it may be difficult for non-professionals to operate. In addition, manual operation also takes a certain amount of time and effort, which is not as convenient and fast as the automatic control system.

[0008] Therefore, based on the above technical problems, a heating flow regulating device is proposed. Utility Model Content

[0025] Furthermore, the slide grooves 3 are arranged on the inner wall of the top seat 2 with a circumferential gap, and the slider 9 slides in the slide groove 3 to limit the circular plate 8, preventing the circular plate 8 from rotating synchronously with the moving screw 5, resulting in the inability to drive the sealing block 11 to move up and down.

[0026] Furthermore, the outer ring of the sealed bearing 4 is fixedly connected to the inner wall of the top seat 2 via the bearing seat, and the inner ring of the sealed bearing 4 is connected to the outer wall of the screw 5 by interference fit, so that the sealed bearing 4 fixes and seals the screw 5.

[0027] Furthermore, the cylinder 7 is communicated with the inner cavity of the sealing block 11, and the bottom end of the outer wall of the screw 5 extends into the cylinder 7. The motor 6 causes the screw 5 to rotate, and the screw 5 causes the cylinder 7 to drive the circular plate 8, the slider 9 and the sealing block 11 to move upward. As the sealing block 11 moves upward, the left channel of the cylinder 1 gradually opens, and the liquid flows to the right side through the cylinder 1.

[0028] Furthermore, a sealing gasket is provided on the inner wall of the through hole 10 , and when the sealing block 11 moves upward, it enters the top seat 2 through the through hole 10 , and the sealing gasket in the through hole 10 plays a sealing role to prevent liquid from entering the top seat 2 through the through hole 10 .

[0029] According to the personnel in this field, all the electrical parts and components in this case are universal standard parts or components known to the technical personnel in this field, and their structures and principles can be known to the technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All the electrical parts in this case are connected to the power supply adapted to them through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0030] A specific application of this embodiment is:

[0031] When in use, the liquid flows from left to right, and the left channel of the cylinder 1 is blocked by the sealing block 11 to achieve a closing effect. The motor 6 causes the screw 5 to rotate, and the screw 5 causes the cylinder 7 to drive the circular plate 8, the slider 9 and the sealing block 11 to move upward. As the sealing block 11 moves upward, the left channel of the cylinder 1 gradually opens, and the liquid flows to the right through the cylinder 1. The speed of liquid circulation can be controlled by controlling the upward position of the sealing block 11. When the sealing block 11 moves upward, it enters the top seat 2 through the through hole 10, and the sealing gasket in the through hole 10 plays a sealing role to prevent the liquid from entering the top seat 2 through the through hole 10. Reversing and starting the motor 6 can cause the sealing block 11 to move downward, which can slow down the speed of liquid circulation. When the sealing block 11 moves to the bottom, the left channel of the cylinder 1 is blocked to achieve a closing effect.
