[0027] Example

[0028] This embodiment provides a temperature control and flow regulation device for a source-site linked heating system, such as... Figures 1-4 As shown, it includes: a pipe 1 connected to the pipeline of the source website linkage heating system; a limit ring 2 fixedly connected inside the pipe 1; an installation block 3 fixedly installed on one side of the limit ring 2; symmetrically arranged rotating rods 5 inside the installation block 3; an adjusting plate 11 fixedly connected to the surface of the rotating rod 5; an installation box 4 fixedly installed on the surface of the pipe 1; the rotating rod 5 extends through the surface of the pipe 1 into the installation box 4; a gear 6 is fixedly connected to the upper part of the surface of the rotating rod 5; two sets of gears 6 are meshed; a sealing cover 7 is fixedly connected to the top of the installation box 4; a reduction motor 8 is fixedly installed on the top of the sealing cover 7; the output shaft end of the reduction motor 8 is fixedly connected to a set of rotating rods 5; and the adjusting plate 11 is semi-circular.

[0029] A source-site linkage heating system temperature control and flow regulation device using the above technical solution is provided, which is equipped with an adjustment plate 11. A set of rotating rods 5 are driven to rotate by a reduction motor 8. Under the action of gear 6, the two sets of rotating rods 5 rotate synchronously. The rotation of the rotating rods 5 drives the two sets of adjustment plates 11 to rotate. The rotation of the adjustment plates 11 exposes the gap between the adjustment plate 11 and the limiting ring 2, allowing water to flow through. The flow rate is regulated by changing the rotation angle of the adjustment plate 11. No manual adjustment is required, making it easy to use.

[0030] To monitor the water temperature inside pipe 1, an installation rod 9 is fixedly connected inside pipe 1. A temperature sensor 10 is fixedly connected to one end of the installation rod 9, and the temperature sensor 10 is located in the center inside pipe 1. Two sets of installation rods 9 and temperature sensors 10 are provided to monitor the temperature on both sides of the regulating plate 11.

[0031] To reduce wear on gear 6, the mounting box 4 is filled with lubricating oil, and a sealing ring is installed at the connection between the rotating rod 5 and the pipe 1. The sealing ring prevents water leakage at the connection between pipe 1 and rotating rod 5. The lubricating oil is used to lubricate gear 6.

[0032] To improve the sealing effect of the regulating plates 11, both sets of regulating plates 11 are fitted against one side of the limiting ring 2, and a sealing plate is provided at the connection between the regulating plates 11 and the limiting ring 2. By fitting the regulating plates 11 against the limiting ring 2, the inside of the pipe 1 is sealed, and the water is cut off.

[0033] To ensure the sealing effect of the adjusting plate 11, a mounting bracket 12 is fixedly connected inside the pipe 1, and a tension spring 13 is fixedly connected between the mounting bracket 12 and the adjusting plate 11. After the reduction motor 8 is de-energized, the adjusting plate 11 moves towards the limiting ring 2 under the action of the tension spring 13, and fits against the limiting ring 2 to seal the pipe 1.

[0034] In order to ensure that each set of adjustment plates 11 is fully sealed, tension springs 13 are symmetrically arranged on the surface of the mounting bracket 12, and the two sets of tension springs 13 are respectively arranged corresponding to the two sets of adjustment plates 11.

[0035] To improve the service life of the adjusting plate 11, an anti-corrosion layer is provided on the surface of the adjusting plate 11. The anti-corrosion layer can be a polyurethane coating, epoxy coating, plastic coating, etc. The diameter of the adjusting plate 11 is larger than the minimum inner diameter of the limiting ring 2 to improve the sealing effect. The geared motor 8 is set as an existing self-locking motor.

[0036] Furthermore, the geared motor 8 has a built-in DSP controller of model TMS320F2812. The DSP controller is electrically connected to the geared motor 8 and the temperature sensor 10 respectively. It is used to control the operation of the geared motor 8 and change the rotation angle of the regulating plate 11 according to the detection signal of the temperature sensor 10, so as to automatically regulate the flow.

[0037] In summary, the temperature control and flow regulation device for a source-site linked heating system provided in this embodiment has the following advantages: An regulating plate 11 is provided, which is driven by a reduction motor 8 to rotate a set of rotating rods 5. Under the action of the gear 6, the two sets of rotating rods 5 rotate synchronously. The rotation of the rotating rods 5 drives the two sets of regulating plates 11 to rotate. The rotation of the regulating plates 11 exposes a gap between the regulating plate 11 and the limiting ring 2, allowing water to flow through. By changing the rotation angle of the regulating plate 11, the flow rate is adjusted. No manual adjustment is required, making it convenient to use.

[0038] In use, pipe 1 is installed on the pipeline of the source website linkage heating system. When the power is on, the regulating plate 11 is driven by the tension spring 13 to rotate along the mounting block 3, so that the regulating plate 11 is in contact with the limiting ring 2, thus cutting off the water flow in pipe 1. When it is necessary to adjust the flow rate of pipe 1, the reduction motor 8 is started. The reduction motor 8 drives a set of rotating rods 5 to rotate. Under the action of gear 6, the two sets of rotating rods 5 rotate synchronously. The rotation of the rotating rods 5 drives the two sets of regulating plates 11 to rotate. The rotation of the regulating plate 11 exposes the gap between the regulating plate 11 and the limiting ring 2, allowing water to flow through. The flow rate is adjusted by changing the rotation angle of the regulating plate 11. No manual adjustment is required, making it easy to use.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
