Description

A smart thermostatic valve for radiators Technical Field

[0001] This invention relates to the field of thermostatic valve technology for radiators, specifically to an intelligent thermostatic valve for radiators. Background Technology

[0002] Intelligent thermostatic valves are widely used in radiators, primarily for regulating indoor temperature as a means of energy saving. They can generally be categorized into steam-type thermostatic valves, liquid-type thermostatic valves, solid-type thermostatic valves, and metal plate thermostatic valves. After prolonged use, scale can accumulate on intelligent thermostatic valves, leading to a decrease in temperature control accuracy, a common problem. Therefore, this paper proposes a design for an intelligent thermostatic valve used in radiators to address this issue.

[0003] A smart thermostatic valve is a temperature control device installed on the radiator inlet valve. It controls the temperature by adjusting the flow rate of hot water in the radiator inlet valve. If the water contains a large amount of impurities, long-term use may cause a large amount of scale to accumulate on the smart thermostatic valve, affecting temperature control and resulting in some energy waste. The smart thermostatic valve has a gear structure inside. After long-term operation, if it is not lubricated in time, the gears will wear out faster, causing not only financial losses but also further reduction in temperature control accuracy and more energy waste.

[0004] To address the above issues, a smart thermostatic valve for radiators is proposed. Summary of the Invention

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] To address the technical problem of decreased temperature control accuracy caused by excessive scale buildup in intelligent thermostatic valves after prolonged use, as shown in Figures 1-14, the following preferred technical solutions are provided:

[0039] A smart thermostatic valve for radiators includes a hollow protective shell 1 and a load-bearing plate 2 fixedly installed at the bottom of the hollow protective shell 1. The hollow protective shell 1 protects the internal components, while the load-bearing plate 2 supports and secures the internal components. A control component 3 is fixedly installed on the top surface of the load-bearing plate 2 to control and coordinate the internal components. A hollow threaded post 8 is fixedly installed on the bottom surface of the load-bearing plate 2, threaded to the radiator's inlet valve for mounting the smart thermostatic valve. A power supply component 7 is fixedly installed on the inner wall of the hollow protective shell 1, electrically connected to the control component 3 and connected to the outer wall of the hollow protective shell 1; the power supply component 7 ensures the normal operation of the smart thermostatic valve.

[0040] A drive assembly 4 is fixedly installed on the top surface of the load-bearing plate 2 to drive the operation of the components. The drive assembly 4 is electrically connected to the control assembly 3 and the power supply assembly 7, forming a closed loop. The power supply assembly 7 supplies power to the drive assembly 4, and the control assembly 3 controls the drive assembly 4 to drive the components to operate, thereby realizing the regulating function of the intelligent thermostatic valve. An adjustment assembly 5 is installed through the load-bearing plate 2. The adjustment assembly 5 is meshed with the drive assembly 4, and the adjustment assembly 5 is vertically slidably installed in the inner cavity of the hollow threaded column 8. The drive assembly 4 drives the adjustment assembly 5 to rotate. During the rotation, the telescopic end of the adjustment assembly 5 can telescopically slide in the inner cavity of the hollow threaded column 8 to adjust the hot water flow of the radiator inlet valve, thereby achieving the purpose of temperature regulation.

[0041] A descaling component 6 is fixedly installed on the top surface of the load-bearing plate 2. The descaling component 6 is installed through the adjusting component 5 and is meshed with the driving component 4. The adjusting component 5 and the descaling component 6 are coaxially aligned and simultaneously mesh with the driving component 4. When the driving component 4 rotates, the adjusting component 5 and the descaling component 6 rotate in opposite directions. During this rotation, the descaling component 6 descals the bottom surface of the extended end of the adjusting component 5, preventing excessive scale buildup and ensuring accurate temperature control. The counter-rotation of the adjusting component 5 and the descaling component 6 provides better descaling than rotation in the same direction.

[0042] A hydraulic assembly 9 is fixedly installed on the top surface of the load-bearing plate 2. The compression end of the hydraulic assembly 9 is fixedly connected to the adjusting assembly 5, and the hydraulic end of the hydraulic assembly 9 is connected to the hollow threaded column 8. Several scraping components 10 are embedded and slidably arranged on the bottom surface of the hollow threaded column 8, and the scraping components 10 are connected to the bottom surface of the hollow threaded column 8. During the extension process of the extending end of the adjusting assembly 5, it will not squeeze the hydraulic oil inside the hydraulic assembly 9. When the extending end of the adjusting assembly 5 returns to its original position, it will squeeze the hydraulic oil inside the hydraulic assembly 9. The hydraulic oil in the hydraulic assembly 9 flows through the hollow threaded column 8 to the scraping components 10, causing the scraping components 10 to move closer to the center of the hollow threaded column 8 until they are slidably mounted on the outer peripheral wall of the extending end of the adjusting assembly 5, thereby removing scale from the outer peripheral wall of the extending end of the adjusting assembly 5.

[0043] The descaling component 6 includes a U-shaped frame 61 fixedly mounted on the top surface of the load-bearing plate 2 and a hollow rotating shaft 62 rotatably mounted within the upper part of the top surface of the U-shaped frame 61. The U-shaped frame 61 limits the movement of the hollow rotating shaft 62. A driven gear 63 is fixedly sleeved on the outer circumference of the upper end of the hollow rotating shaft 62, and the driven gear 63 meshes with the drive component 4. The driven gear 63 transmits the kinetic energy from the drive component 4 to the hollow rotating shaft 62, causing it to rotate. A cleaning component 64 is vertically slidably mounted within the inner wall of the hollow rotating shaft 62. During the rotation of the hollow rotating shaft 62, the cleaning component 64 rotates along with it. The lower end of the cleaning component 64 is rotatably mounted within the inner cavity of the adjusting component 5. The top surface of the cleaning component 64 is elastically connected to the top surface of the inner cavity of the hollow rotating shaft 62 by a spring 65, which returns the cleaning component 64 to its original position.

[0044] The hollow protective shell 1 includes a shell 11 and several transparent covers 12 fixedly installed on the outer wall of the shell 11. The transparent covers 12 are provided to facilitate personnel to observe the operating status of the internal components of the shell 11 and to facilitate the judgment of whether the intelligent thermostatic valve has malfunctioned.

[0045] The control component 3 includes a support frame 31 fixedly installed on the top surface of the load-bearing plate 2 and an intelligent circuit board 32 fixedly installed on the support frame 31. The intelligent circuit board 32 is equipped with a temperature sensor 33 (model PT100) and a controller 34.

[0046] The drive assembly 4 includes a base 41 fixedly mounted on the top surface of the load-bearing plate 2 and a motor 42 fixedly mounted on the base 41. The output end of the motor 42 is fixedly mounted with a drive gear 43. The drive gear 43 is meshed with the driven gear 63 and the adjustment assembly 5 respectively. The motor 42 drives the drive gear 43 to rotate, transmitting kinetic energy to the driven gear 63 and the adjustment assembly 5.

[0047] The power supply component 7 includes a battery compartment 71 fixedly installed on the inner wall of the hollow protective shell 1 and an energy storage battery 73 embedded in the inner cavity of the battery compartment 71. A battery protective shell 72 is fixedly installed on the outer wall of the hollow protective shell 1, and the installation position of the battery protective shell 72 is aligned with the opening position of the battery compartment 71.

[0048] The adjusting assembly 5 includes a fixed frame 51 fixedly installed on the top surface of the load-bearing plate 2 and a hollow threaded rod 52 rotatably installed through the inner cavity of the fixed frame 51. A driven gear 53 is fixedly sleeved on the outer wall of the upper end of the hollow threaded rod 52, and the driven gear 53 is meshed with the driving gear 43. A hollow lifting block 54 is threadedly connected to the outer wall of the hollow threaded rod 52, and the hollow lifting block 54 is embedded and slidably disposed on the inner wall of the hollow threaded column 8. The driving gear 43 drives the hollow threaded rod 52 to rotate through the driven gear 53. Under the action of the thread, the hollow lifting block 54 slides in the inner cavity of the hollow threaded column 8 to adjust the hot water flow of the radiator inlet valve, thereby achieving the purpose of temperature regulation.

[0049] The hollow lifting block 54 includes a lifting block body 541 threadedly connected to the outer wall of the hollow threaded rod 52 and a limiting annular groove 542 formed on the inner wall of the inner cavity of the lifting block body 541. The lower end of the cleaning component 64 is embedded and rotatably installed in the inner cavity of the limiting annular groove 542. The limiting annular groove 542 limits the cleaning component 64, allowing the cleaning component 64 to move vertically with the hollow lifting block 54 during rotation, thus achieving descaling of the bottom of the lifting block body 541 simultaneously during temperature adjustment.

[0050] The cleaning component 64 includes a long rod 641 embedded vertically and slidably disposed on the inner wall of the hollow rotating shaft 62, and several fixing blocks 642 fixedly disposed on the outer peripheral wall of the lower end of the long rod 641. The fixing blocks 642 are all embedded and slidably disposed within the inner cavity of the limiting annular groove 542. Several scrapers 643 are fixedly mounted on the bottom surface of the long rod 641, and the scrapers 643 are all tightly fitted and slidably disposed on the bottom surface of the lifting block body 541. The scrapers 643 are fastened to the bottom surface of the long rod 641 by reinforcing members 644. During the rotation of the hollow rotating shaft 62, the long rod 641 will rotate, which in turn will drive the scrapers 643 to rotate, thus descaling the bottom surface of the lifting block body 541.

[0051] The hollow rotating shaft 62 includes a hollow rotating shaft body 621 embedded and rotatably mounted in the middle of the top surface of the inner cavity of the U-shaped frame 61, and several long sliding grooves 622 formed on the inner wall of the inner cavity of the hollow rotating shaft body 621. A long rod 641 is embedded and slidably disposed within the inner cavity of the long sliding groove 622. The long sliding grooves 622 limit the movement of the long rod 641, allowing it to rotate with the hollow rotating shaft body 621. During rotation, the long rod 641 can simultaneously slide within the inner cavity of the long sliding groove 622, thereby achieving the aforementioned descaling effect.

[0052] The intelligent thermostatic valve is threaded onto the radiator's inlet valve via a hollow threaded post 8. The indoor temperature is detected by a temperature sensor 33 on the intelligent circuit board 32. The controller 34 determines whether the set threshold has been reached, and then controls the drive assembly 4 to drive the regulating assembly 5 and the descaling assembly 6. The descaling assembly 6 rotates in the opposite direction to the regulating assembly 5. During rotation, the hollow threaded rod 52 on the regulating assembly 5 drives the hollow lifting block 54 to slide and extend within the hollow threaded post 8, regulating the hot water flow through the radiator's inlet valve and thus controlling the indoor temperature. Meanwhile, the hollow rotating shaft 62 on the descaling assembly 6 drives the cleaning assembly 64 to rotate simultaneously, and the cleaning assembly 64 slides along with the hollow lifting block 54 during rotation. This setup allows for simultaneous temperature regulation and descaling of the hollow lifting block 54, preventing a decrease in temperature regulation accuracy due to scale buildup. Furthermore, it eliminates the need to disassemble the intelligent thermostatic valve for descaling, saving manpower.

[0053] To address the technical problem of incomplete scale removal from intelligent thermostatic valves, as shown in Figure 10-12, the following preferred technical solution is provided:

[0054] The load-bearing plate 2 includes a load-bearing plate body 21 fixedly installed at the bottom of the housing 11 and several through slots 22 opened on the top surface of the load-bearing plate body 21.

[0055] The hollow threaded column 8 includes a threaded column body 81 fixedly installed on the bottom surface of the load-bearing plate 21 and several oil flow through holes 82 opened on the top surface of the threaded column body 81. The hydraulic end of the hydraulic component 9 is connected to the scraping component 10 through the oil flow through holes 82. Four pairs of grooves 83 are opened on the bottom surface of the threaded column body 81, and the scraping component 10 is correspondingly embedded and slidably disposed in the inner cavity of the four pairs of grooves 83. When the hydraulic component 9 is running, the hydraulic oil in the inner cavity of the hydraulic component 9 will flow into the scraping component 10 through the oil flow through holes 82, which will provide hydraulic pressure to the scraping component 10, causing the scraping component 10 to move closer to the center of the threaded column body 81 until it is tightly fitted to the outer peripheral wall of the lifting block body 541, thereby removing scale from the outer peripheral wall of the lifting block body 541.

[0056] The hydraulic assembly 9 includes several support columns 92 fixedly installed on the top surface of the load-bearing plate 21 and a hydraulic cylinder 91 fixedly installed on the support columns 92. A push rod 93 is slidably installed through the bottom of the hydraulic cylinder 91. The push rod 93 is installed through the inner cavity of the through groove 22. The lower end of the push rod 93 is fixedly connected to the top surface of the lifting block body 541. An oil pipe 94 is fixedly installed on the top surface of the hydraulic cylinder 91. The end of the oil pipe 94 away from the hydraulic cylinder 91 is connected to the oil flow through hole 82. When the lifting block body 541 returns to its original position, the hydraulic oil inside the hydraulic cylinder 91 is squeezed by the push rod 93. The squeezed hydraulic oil flows through the oil pipe 94 and the oil flow through hole 82 to the inner cavity of the scraping assembly 10, which drives the scraping assembly 10 to operate and remove scale from the outer periphery of the lifting block body 541.

[0057] The scraping assembly 10 includes several elastic telescopic members 101 fixedly installed on the bottom surface of the threaded column body 81 and arc-shaped descaling plates 102 fixedly installed on the extended ends of the elastic telescopic members 101. The elastic telescopic members 101 are connected to the oil flow through hole 82. A pair of sliding columns 103 are fixedly installed on the top surface of the arc-shaped descaling plates 102, and the pair of sliding columns 103 are correspondingly embedded and slidably arranged in the inner cavity of a pair of grooves 83. The elastic telescopic members 101 are elastic. When the lifting block body 541 removes the pressure applied to the hydraulic oil, the elastic telescopic members 101 can squeeze the hydraulic oil back into the inner cavity of the hydraulic cylinder 91 through the oil pipe 94 and the oil flow through hole 82 for the next use.

[0058] During the return process of the lifting block body 541, the hydraulic oil inside the hydraulic cylinder 91 is squeezed by the push rod 93. The squeezed hydraulic oil flows through the oil pipe 94 and the oil flow through hole 82 to the inner cavity of the elastic telescopic member 101. Under the action of hydraulic pressure, the elastic telescopic member 101 drives the arc-shaped descaling plate 102 to slide towards the center of the threaded column body 81 until the arc-shaped descaling plate 102 is tightly attached to the outer peripheral wall of the lifting block body 541. Through the above-mentioned arrangement, the scale on the outer peripheral wall of the lifting block body 541 can be scraped off. Combined with the above-mentioned descaling of the bottom surface of the lifting block body 541, the descaling of the lifting block body 541 is more thorough, further improving the temperature control accuracy of the intelligent thermostatic valve.

[0059] To address the technical problem of accelerated wear caused by prolonged lack of lubrication in the internal gear structure of intelligent thermostatic valves, as shown in Figure 14, the following preferred technical solution is provided:

[0060] The driving gear 43 includes a gear body 431 fixedly installed at the output end of the motor 42 and several holes 432 opened on the outer wall of the gear body 431. Lubricating material 433 is embedded and fixedly installed in the inner cavity of each hole 432.

[0061] Friction occurs during the meshing and rotation of the gear body 431 with driven gear 63 and driven gear 53. This friction causes the lubricating material 433 to be ground into small particles that adhere to the outer walls of the gear body 431, driven gear 63, and driven gear 53, forming an oil film that reduces wear between them.

[0062] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
