Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning (HVAC) engineering technology, and in particular to a heating control device for HVAC engineering. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's requirements for quality of life, residential areas and shopping malls need heating in winter. Heating, ventilation and air conditioning (HVAC) projects transfer heat energy to users in buildings through heating pipes to meet people's needs for indoor temperature in winter.

[0003] Traditional heating methods involve heating water and then distributing it through main pipes to branch pipes, which connect to different rooms. Hot water is then delivered to the rooms requiring heating, and radiators release heat to raise the indoor temperature. Because the flow rate in the main pipes is centrally controlled, adjusting the flow rate across the entire main pipe is necessary, resulting in a uniform temperature across all rooms and failing to meet the diverse temperature needs of different users. To address this issue, existing technology involves installing regulating valves on individual branch pipes. Manually turning these valves controls the flow rate and adjusts the indoor heating temperature. However, in practice, this is affected by weather conditions, requiring repeated valve adjustments, which is extremely inconvenient and reduces the overall convenience of the system.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a heating control device for HVAC engineering, including a mounting base 1. A valve body 3 is fixedly connected to the front side of the outer wall of the mounting base 1, and a valve seat 4 is fixedly connected to the inner wall of the valve body 3. When the entire device is in the closed state, the valve disc 12 will tightly fit against the valve seat 4. Due to the good sealing between the two, the heating medium can be completely blocked from passing through, causing the corresponding heating branch or heating area to stop heating. When it is necessary to adjust the heating flow rate, under the driving action of a series of subsequent components, the valve disc 12 will move relative to the valve seat 4, forming a certain gap between the two, through which the heating medium can flow. A valve cover 5 is provided on the top of the valve body 3 to close the top opening of the valve body 3, forming a... The relatively enclosed internal space effectively prevents foreign objects such as dust, impurities, and moisture from the external environment from entering the valve body 3. A rotating rod 6 is rotatably connected to the top of the valve cover 5, serving to connect the upper and lower components. A large gear 7 is fixedly connected to the top of the rotating rod 6, and a threaded rod 8 is fixedly connected to the bottom of the rotating rod 6, penetrating the valve cover 5. The rotation of the large gear 7 drives the threaded rod 8 below to rotate via the rotating rod 6. A connecting plate 9 is threadedly connected to the outer wall of the threaded rod 8. Vertical rods 10 are fixedly connected to the left and right sides of the bottom of the outer wall of the valve cover 5. Both vertical rods 10 are slidably connected to the connecting plate 9, providing precise directional guidance for the vertical linear movement of the connecting plate 9. When the threaded rod 8 rotates, the connecting plate 9 can only move along the vertical rods 10. The axial direction of the mounting base 10 is moved. Connecting columns 11 are fixedly connected to the front and rear sides of the bottom of the connecting plate 9. Valve discs 12 are fixedly connected to the bottom ends of the two connecting columns 11. The valve discs 12 are securely connected to the connecting plate 9 via the connecting columns 11 and are driven to move up and down by the threaded rod 8. Due to the transmission effect of the connecting columns 11, the valve discs 12 also move up and down synchronously, thereby changing the gap between them and the valve seat 4. A thermometer 13 is fixedly connected to the top left side of the mounting base 1. The thermometer 13 detects the indoor temperature and compares it with the set temperature value. A processor 14 is fixedly connected to the top right side of the mounting base 1. The processor 14 receives the temperature comparison value transmitted by the thermometer 13 and calculates the number of rotations of the reduction motor 15. A geared motor 15 is fixedly connected to the top center of the outer wall of the mounting base 1. A small gear 16 is fixedly connected to the output end of the geared motor 15. After receiving the rotation command sent by the processor 14, the geared motor 15 drives the small gear 16 to rotate. The small gear 16 meshes with the large gear 7. When the small gear 16 rotates, it drives the large gear 7 to rotate, thereby controlling the movement distance of the valve disc 12. An installation mechanism 2 is provided on the outer wall of the mounting base 1. The installation mechanism 2 is used to fix the mounting base 1. A water inlet pipe 25 is connected to the right side of the outer wall of the valve body 3, and a water outlet pipe 26 is connected to the left side of the outer wall of the valve body 3. The water inlet pipe 25 is the channel for the heating medium to enter in the entire heating control device, and the water outlet pipe 26 is connected to the left side of the outer wall of the valve body 3, which is the channel for the heating medium to flow out of the valve body 3.A sealing gasket 21 is fixedly connected to the bottom of the valve cover 5. The outer wall of the sealing gasket 21 has reserved holes 22 around its perimeter. Bolts 23 are threaded around the outer wall of the valve cover 5. The bottom ends of multiple bolts 23 pass through the sealing gasket 21 and are threaded to the valve body 3. When the valve cover 5 is installed on the valve body 3, the sealing gasket 21 is sandwiched between the two. With its own elastic deformation ability, it can fit tightly against the contact surface of the valve cover 5 and the valve body 3, thereby blocking the possible leakage channel of the heating medium. The bottom ends of the two uprights 10 are fixedly connected to limit rings 24. The diameter of the limit rings 24 is larger than the diameter of the uprights 10. The limit rings 24 are used to limit the downward movement distance of the connecting plate 9 and prevent the connecting plate 9 from falling off the threaded rod 8.

[0032] Reference Figure 4 and Figure 5 The mounting mechanism 2 includes multiple threaded holes 201 and multiple bolts 202. The bolts 202 are respectively located on the left and right sides of the outer wall of the mounting base 1. The threaded holes 201 are respectively located on the left and right sides of the outer wall of the mounting base 1. The bolts 202 are threadedly connected to the mounting base 1 through the threaded holes 201. The threaded holes 201 have internal threads, the specifications of which match the external threads of the bolts 202, allowing the bolts 202 to be screwed into them through threaded engagement, thus achieving a threaded connection between the bolts 202 and the mounting base 1. Mounting plates 203 are rotatably connected to the outer walls of each bolt 202. The mounting plates 203 can rotate around the central axis of the bolts 202. The wire rotates freely. The mounting plate 203 is used to fix it to the mounting surface, thereby supporting the mounting base 1. The outer walls of the multiple mounting plates 203 are provided with threaded holes 204. The inner walls of the multiple threaded holes 204 are threaded with screws 205. After the mounting plate 203 has been initially positioned and attached to the target mounting surface by the bolts 202, the screws 205 are used to further fix the mounting plate 203 to the mounting surface. The front ends of the multiple screws 205 are fixedly connected with tapered feet 206. As the screws 205 are screwed into the mounting surface along the threaded holes 204, the tapered feet 206 first contact the mounting surface. Due to their sharp shape, they are more likely to pierce the mounting surface.

[0033] Reference Figure 1 , Figure 3 and Figure 4A connecting rod 17 is fixedly connected to the top center of the large gear 7, and a handle 18 is fixedly connected to the top of the connecting rod 17. When the geared motor is damaged, the valve disc 12 can be moved up and down by turning the handle 18. The top of the water outlet pipe 26 is connected to a liquid collection pipe 19, and a thermometer 20 is fixedly connected to the top of the liquid collection pipe 19. After the liquid is drawn through the liquid collection pipe 19, the thermometer 20 can measure the temperature of the liquid. A controller 27 is fixedly connected to the right side of the outer wall of the mounting base 1. The controller 27 is electrically connected to the geared motor 15, the thermometer 13 and the processor 14 respectively. The controller 27 is electrically connected to multiple electrical appliances and can control multiple electrical appliances at the same time, making the automation level of the device higher.

[0034] Working principle: Before using the device, first set the indoor temperature preset value. The thermometer 13 measures the indoor temperature and compares it with the set indoor temperature value. After comparison, the comparison data is transmitted to the processor 14. The processor 14 calculates the valve opening degree and the number of rotations of the 15 based on the comparison value. Then, the reduction motor 15 starts to work. The output end of the reduction motor 15 drives the pinion 16 to rotate. The pinion 16 meshes with the large gear 7 at the top of the rotating rod 6. The rotational motion of the pinion 16 is transmitted to the large gear 7, causing the large gear 7 to rotate at the same linear velocity but different angular velocity, driving the rotating rod 6. The threaded rod 8 rotates synchronously with the rotating rod 6. When the threaded rod 8 rotates, the connecting plate 9 moves up and down along the upright rod 10. When the connecting plate 9 moves up and down, the valve disc 12 also moves up and down. The valve disc 12 and the valve seat 4 cooperate to control the opening and closing degree of the fluid passage. When the valve disc 12 moves upward, the gap between the valve disc 12 and the valve seat 4 increases, the valve opening increases, and the flow rate of the heating fluid through the valve body 3 increases. When the valve disc 12 moves downward, the gap between the valve disc 12 and the valve seat 4 decreases, the valve opening decreases, and the flow rate of the heating fluid decreases accordingly, thereby controlling the flow rate of the fluid.

[0035] Furthermore, select the corresponding threaded hole 201 according to the installation position of the mounting base 1, align the bolt 202 with the threaded hole 201 on the mounting base 1, rotate the mounting plate 203 to adjust the mounting plate 203 to be parallel to the mounting surface, and then rotate the bolt 202 to screw the bolt 202 into the threaded hole 201, thereby driving the mounting plate 203 to move towards the mounting base 1 and fit against the mounting base 1. Then move the mounting base 1 towards the mounting surface so that the mounting plate 203 fits against the mounting surface, pass the screw 205 through the threaded hole 204, and turn the screw 205 so that the screw 205 enters the mounting surface, thus fixing the mounting plate 203. The mounting plate 203 supports the mounting base 1, and the tapered foot 206 can quickly screw the screw 205 into the mounting surface.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
