Description

Technical Field

[0001] This invention relates to the field of fluid valve technology, specifically to a constant heat control valve and control method. Background Technology

[0002] A constant heat control valve generates a constant amount of heat by supplying a liquid. Since the liquid flowing through it has a specific temperature, maintaining a constant amount of heat per unit time requires controlling the liquid's flow rate. When the temperature is too high, the flow rate needs to be reduced; when the temperature is too low, the flow rate needs to be increased accordingly.

[0003] Existing control valves generally control the opening and closing of channels by opening and closing the valve core. However, for the aforementioned constant heat control valve, firstly, existing control valves cannot solve the problem of adjustment accuracy, and secondly, the energy generated by the liquid during transportation is not utilized, resulting in low energy utilization. Therefore, a constant heat control valve and control method are provided. Summary of the Invention

[0045] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0046] Example 1

[0047] Please see Figures 1 to 13 The present invention preferably provides a technical solution: a mechanical heat constant control valve, comprising: a valve pipe 111, an inlet 112 and an outlet 113 disposed before and after the valve pipe 111; and a valve body disposed within the valve pipe 111; the valve body includes a frame 211, and a first blade assembly and a second blade assembly disposed within the frame 211 in a front-to-back arrangement along the water flow direction; a first coil 212, a battery 214 and a second coil 215 are sequentially disposed on the frame 211; the first blade assembly is rotatable relative to the second blade assembly, and a first magnet 313 is disposed at the end of the first blade assembly and placed within the first coil 212; under the action of water flow, the first blade assembly, under the combined action of the first coil 212 and the first magnet 313, is used for energy storage of the battery 214; and a second magnet 412 disposed at the end of the second blade assembly and placed within the second coil 215; the battery 214 outputs current to the second coil 215; under the combined action of the second coil 215 and the second magnet 412, the second blade assembly is actively controlled to rotate, thereby controlling and regulating the liquid flow rate.

[0048] This design, through the first blade assembly and the second blade assembly arranged front and rear along the water flow direction within the frame 211, such as Figure 1 , 2 As shown in Figures 4 and 5, the first blade assembly is freely rotatable and located at the front end of the second blade assembly;

[0049] In the first process, the energy storage process of the first blade assembly, under the action of water flow, it drives the first magnet 313 to rotate in the area of ​​the first coil 212. At this time, similar to the principle of a generator, mechanical energy is converted into electrical energy and stored in the battery 214.

[0050] The second process is the active flow regulation process of the second blade assembly. The battery 214 provides current to the second coil 215. Under the action of several second magnets 412, similar to the principle of an engine, the second coil 215 and the battery 214 work together to drive the entire second blade assembly to rotate counterclockwise or clockwise to promote or inhibit the flow.

[0051] Example 2

[0052] In another embodiment of the present invention, the first blade assembly includes a bushing 316 and first blades 311 arranged in a ring on the outer wall of the bushing 316. The first blades 311 are inclined at a certain angle to the bushing 316. The first magnet 313 is detachably installed at the radial outer end of the first blade 311. The frame 211 has a plurality of grooves 220 on the inner wall near the first blade assembly. Each groove 220 is provided with a ring of stops 221. Each stop 221 has an inverted triangular structure. The frame 211 also has a plurality of guide grooves 312 on each first blade 311. The ends of each guide groove 312 converge in the groove 220.

[0053] In this embodiment, a design structure for a first blade assembly is further provided, which is as follows: Figure 3 , 4 As shown in Figure 6, since the first blade assembly can rotate freely, specifically, it consists of several first blades 311 arranged at a certain angle on the bushing 316, and several guide grooves 312 are formed on the first blades 311. The guide grooves 312 are arc-shaped and converge at the end of the groove 220. Several baffles 221 with an inverted triangular structure are provided inside the groove 220. Figure 6 As shown, when the liquid is guided by the flow channel 312 to the groove 220 where the frame 211 is located, when the water flow acts on the baffle 221, it will deliver an impact force in the opposite direction to the liquid. Finally, through this reverse impact, it acts on the corresponding first blade 311, thereby accelerating the rotation of the entire first blade assembly. Through the first magnet 313 at the end of the first blade 311, under the combined action of the first magnet 313 and the first coil 212, electrical energy is stored and enters the battery 214.

[0054] Example 3

[0055] In another embodiment of the present invention, the second blade assembly includes a magnetic flux channel assembly disposed at the rear end of the frame 211. The magnetic flux channel assembly extends to the center of the frame 211 and is vertically disposed with a rotatable assembly tube 911. An adjustment bracket assembly is disposed on the front section of the assembly tube 911 near the magnetic flux channel assembly. The adjustment bracket assembly is disposed with second blades 411 arranged in a ring at a certain angle. A second magnet 412 is detachably mounted on the radial outer end of the second blade 411. The magnetic flux channel assembly is used to control the deflection of the adjustment bracket assembly and thereby change the tilt angle of the second blade 411. A bushing 316 is rotatably mounted on the rear section of the assembly tube 911 away from the magnetic flux channel assembly.

[0056] In this embodiment, the further configured second blade assembly allows for active regulation of the liquid flow rate. It can function in both ways: increasing and decreasing flow rate.

[0057] The deceleration process involves increasing resistance to the flowing liquid, which acts as a reverse inhibition to reduce the liquid's flow velocity.

[0058] The process of increasing speed is to add a driving force to the liquid, which positively promotes an increase in its flow rate.

[0059] The design of the second blade assembly has two variations:

[0060] like Figure 4 and 13 As shown, when water flows from the first blade assembly to the second blade assembly, as... Figure 13 As shown, when the water flow acting laterally by the first blade assembly acts on the second blade 411, at this angle, the individual second blade 411 tends to rotate clockwise, and the entire second blade 411 tends to move counterclockwise. Promoting or inhibiting the above two tendencies can increase or decrease the water velocity. Increasing the flow velocity increases the heat per unit time, while decreasing the water velocity decreases the heat per unit time.

[0061] Specifically;

[0062] One approach is as follows: For a single second blade 411, the water flow exerts a force on the second blade 411, causing it to tend to move clockwise. At this time, controlling the single second blade 411 to rotate counterclockwise suppresses the rotational tendency of the second blade 411. In this case, the angle between the water flow and the second blade 411 increases, thus reducing the flow velocity. Conversely, controlling the single second blade 411 to rotate clockwise promotes the rotational tendency of the second blade 411. In this case, the angle between the water flow and the second blade 411 decreases, allowing the water to flow more smoothly and reducing resistance, thus increasing the flow velocity.

[0063] Another approach is: the overall drive control of the second blade assembly, such as... Figure 5 As shown, the battery 214 supplies power to the second coil 215. Under the combined action of the second coil 215 and the second magnet 412, simulating the principle of a motor, the second blade 411 is driven to rotate as a whole. Figure 4 , 13 As shown, when the second blade 411 rotates counterclockwise as a whole, it promotes the overall counterclockwise rotation of the second blade assembly, which is equivalent to reducing the obstruction to the water flow and increasing the flow velocity. When the second blade 411 rotates clockwise as a whole, it inhibits the overall counterclockwise rotation of the second blade assembly, which is equivalent to increasing the obstruction to the water flow and reducing the flow velocity.

[0064] Example 4

[0065] In another embodiment of the present invention, the magnetofluid channel assembly includes a first damping control module 711 fixed to the end of the frame 211, a first connecting electrode 712 disposed at the radially outer end of the first damping control module 711, and a first damping cavity 713 opened inside the first damping control module 711, and a second damping control module 811 assembled with the first damping control module 711, a second connecting electrode 812 disposed at the radially outer end of the second damping control module 811, a second damping cavity 813 opened inside the second connecting electrode 812, the bottom of the second damping cavity 813 communicating with the first damping cavity 713 and respectively containing magnetofluid.

[0066] Furthermore, the adjusting bracket assembly is fixed to the connecting shaft 421 at the bottom of the second blade 411. The bottom end of the connecting shaft 421 passes through the assembly hole 912 on the assembly tube 911 and is fixed with a transmission component 420. The transmission component 420 has two sets of transmission grooves 4201. A first damping shaft 511 rotates inside the assembly tube 911. The first damping shaft 511 has a through groove 514, a first protrusion 513, and a first damping plate 512 arranged sequentially. The first protrusion 513 is limited within one of the transmission grooves 4201. The first damping plate 512 is placed in the first damping cavity 713. When current is applied to the first connecting electrode 712, the magnetohydrodynamic fluid in the first damping cavity 713 acts on the first damping plate 512 to control the position of the first damping shaft 511. 1. Braking: A rotatable second damping shaft 611 is provided in the end of the first damping shaft 511 near the first damping plate 512. The second damping shaft 611 is provided with a second protrusion 613 and a second damping plate 612 in sequence. The second protrusion 613 passes through the through groove 514 and is limited in another transmission groove 4201. The second damping plate 612 is placed in the second damping cavity 813. When current is applied to the second connecting electrode 812, the magnetohydrodynamic fluid in the second damping cavity 813 acts on the second damping plate 612 to control the braking of the second damping shaft 611 on which it is located. Through the relative braking of the second damping shaft 611 and the first damping shaft 511, the inclination trend of the second blade 411 is controlled under the action of the transmission component 420, thereby promoting or inhibiting the liquid flow rate.

[0067] Furthermore, it also includes a sleeve 1011, which is sleeved on the section of the adjusting bracket assembly where the assembly tube 911 is located. The sleeve 1011 has a polygonal structure for arranging the inclined second blades 411, and a number of mounting holes 1012 are opened on the sleeve 1011. The mounting holes 1012 correspond one-to-one with the assembly holes 912 and are used for the passage of the connecting shaft 421.

[0068] Furthermore, the first connecting electrode 712 and the second connecting electrode 812 are respectively connected to the battery 214 via wires.

[0069] In this embodiment, a combination of a magnetofluidic channel assembly and an adjustment bracket assembly is provided, which can promote or inhibit the tilt angle of a single second blade 411.

[0070] Specifically, such as Figure 7 , 8 As shown in 9, 10, 11 and 12, the assembly of this magnetofluidic channel assembly with the adjusting bracket assembly is achieved by rotating the assembly tube 911. When the second blade assembly is driven to rotate as a whole, the second blade 411 rotates together with the adjusting bracket assembly and its internal first damping shaft 511 and second damping shaft 611.

[0071] like Figure 8 , 9 As shown in Figures 10 and 12, the second protrusion 613 on the second damping shaft 611 passes through the through groove 514 and slides within the transmission groove 4201 on the left side, while the first protrusion 513 on the first damping shaft 511 moves within the transmission groove 4201 on the right side. The connecting shaft 421 is rotatably mounted on the mounting hole 912 where the mounting tube 911 is located. Through the relative rotational tendency of the first damping shaft 511 and the second damping shaft 611, the positions of the first protrusion 513 and the second protrusion 613 are changed, thereby causing the second blade 411 where the connecting shaft 421 is located to adjust its tilt angle. For example, in the second When the blade assembly rotates counterclockwise, to prevent the second blade 411 from rotating clockwise, it is necessary to restrict and prevent the movement of the first protrusion 513 where the first damping shaft 511 is located. This gives the second blade 411 a counterclockwise tendency when it rotates clockwise, thus inhibiting its movement. Similarly, when providing power, the magnitude of the damping rotation of the second damping shaft 611 is controlled to create a promoting deflection tendency for the second blade 411. The final effect is that when the water temperature is too high, the water flow rate is reduced to maintain a constant temperature, requiring the second blade 411 to provide resistance to the water. When the water temperature is too low, the angle is adjusted to control the magnitude of this water resistance, thereby regulating the water flow rate.

[0072] And control the motion state of the first damping shaft 511 and the second damping shaft 611, such as Figure 8 , 9 As shown in Figure 10, through the cooperation of the first damping plate 512 and the first damping cavity 713 at the right end of the first damping shaft 511 and the second damping shaft 611, and the second damping plate 612 and the second damping cavity 813, the magnetic fluid fills the first damping cavity 713 and the second damping cavity 813. When the first connecting electrode 712 and the second connecting electrode 812 are energized, the damping of the magnetic fluid is adjusted by the magnitude of the current, thereby controlling the damping degree of the first damping shaft 511 and the second damping shaft 611, and thus realizing the change of its rotational resistance.

[0073] Furthermore, the battery 214 has a ring-shaped structure and is wrapped around the outer wall of the second coil 215. The first coil 212 is connected to the battery 214 and stores electrical energy in the battery 214. The battery 214 is connected to the second coil 215 and outputs electrical energy to the second coil 215.

[0074] Example 5

[0075] A control method for a mechanically controlled heat constant valve, applied to the aforementioned mechanically controlled heat constant valve, includes the following steps:

[0076] S1: Under the action of water flow, through the energy storage process of the first blade assembly, it drives the first magnet 313 to rotate in the area of ​​the first coil 212, converting mechanical energy into electrical energy and storing it in the battery 214;

[0077] S2: Then the battery 214 provides current to the second coil 215. Under the action of several second magnets 412, the second coil 215 and the battery 214 work together to drive the second blade assembly to rotate clockwise and counterclockwise.

[0078] S3: Furthermore, by combining the magnetofluid channel assembly with the adjustment bracket assembly, the tilt angle of a single second blade 411 is slightly adjusted.

[0079] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.
