Description

Technical Field

[0001] The present invention relates to the field of valve technology, and in particular to an Internet of Things balancing valve. Background Art

[0002] Most methods for achieving hydraulic balance in heating systems, air conditioning systems, and solar energy drainage systems are to install IoT balancing valves in the pipeline, collect the working parameters of each balancing valve, and adjust each balancing valve in the system to the theoretical working position according to the debugging strategy. In the related art, due to the limitation of its own structure, there is a relatively protruding part near the valve core of the balancing valve, which causes the fluid in the valve core to be subjected to large impedance, thereby greatly affecting the flow rate and flow of the heating fluid, and thus resulting in poor heating effect. Summary of the invention

[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0041] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0042] like Figure 1-Figure 5 As shown, the Internet of Things balancing valve according to the embodiment of the present invention includes: a valve body 1, a rubber bushing 15, a first extruded component 3 and a second extruded component 4.

[0043] The valve body 1 includes a mounting portion 11, a first connecting pipe 12 and a second connecting pipe 13. The mounting portion 11 has a first direction (eg Figure 1 The first side surface 111 and the second side surface 112 are arranged relatively in the left-right direction (in the left-right direction), the first connecting tube 12 is arranged on the first side surface 111 and extends in a direction away from the second side surface 112, the second connecting tube 13 is arranged on the second side surface 112 and extends in a direction away from the first side surface 111, and the mounting portion 11 has a mounting cavity 113. The rubber bushing 15 is passed through the mounting portion 11 along the first direction and a part of the rubber bushing 15 is located in the mounting cavity 113, at least a part of the first end of the rubber bushing 15 is located in the first connecting tube 12, at least a part of the second end of the rubber bushing 15 is located in the second connecting tube 13, the first end of the rubber bushing 15 is connected to the first connecting tube 12, and the second section of the rubber bushing 15 is connected to the second connecting tube 13.

[0044] Specifically, Figure 1-Figure 3As shown, the left side of the mounting portion 11 is the first side 111, the right side of the mounting portion 11 is the second side 112, the first connecting tube 12 extends to the left, and the second connecting tube 13 extends to the right. The rubber bushing 15 can be divided into three parts: left, middle, and right along the left-right direction, and the left part of the rubber bushing 15 is located in the first connecting tube 12, the right part of the rubber bushing 15 is located in the second connecting tube 13, and the middle part of the rubber bushing 15 is located in the mounting cavity 113 of the mounting portion 11.

[0045] It is understandable that the two ends of the rubber bushing 15 can be connected to the first connecting tube 12 and the second connecting tube 13 respectively by means of connectors or bonding, and the middle part of the rubber bushing 15 can be deformed when subjected to external force.

[0046] Optionally, the axes of the first connecting tube 12 and the second connecting tube 13 coincide with each other. Preferably, the extending directions of the axes of the first connecting tube 12 and the second connecting tube 13 are consistent with the left-right direction.

[0047] The first extrusion member 3 and the second extrusion member 4 are disposed in the mounting cavity 113 and are respectively arranged relative to the mounting portion 11 along the second direction (eg Figure 1 The rubber bushing 15 is movable in an upper and lower direction (in the upper and lower directions), the second direction is orthogonal to the first direction, and the rubber bushing 15 is located between the first extrusion member 3 and the second extrusion member 4 in the second direction, wherein after the first extrusion member 3 and the second extrusion member 4 contact with the outer peripheral surface of the rubber bushing 15, the moving speed of the first extrusion member 3 toward the second extrusion member 4 is equal to the moving speed of the second extrusion member 4 toward the first extrusion member 3.

[0048] It is understandable that if Figure 2 As shown, the first extrusion member 3 and the second extrusion member 4 can be driven by different driving members or by the same driving member, that is, after the first extrusion member 3 and the second extrusion member 4 come into contact with the outer peripheral surface of the rubber bushing 15, it is sufficient to ensure that the moving speed of the first extrusion member 3 toward the second extrusion member 4 is equal to the moving speed of the second extrusion member 4 toward the first extrusion member 3. In other words, after the first extrusion member 3 and the second extrusion member 4 come into contact with the outer peripheral surface of the rubber bushing 15, the first extrusion member 3 and the second extrusion member 4 simultaneously squeeze the rubber bushing 15, so that the rubber bushing 15 undergoes the same deformation at the squeezed portion, so as to ensure the stability of the fluid flow rate in the rubber bushing 15.

[0049] Therefore, the Internet of Things balancing valve of the embodiment of the present invention can adjust the first extrusion component 3 and the second extrusion component 4 so that the first extrusion component 3 and the second extrusion component 4 simultaneously extrude the rubber bushing 15 at the same speed, so that the rubber bushing 15 can produce uniform deformation to ensure the stable change of the fluid flow rate through the rubber bushing 15.

[0050] In addition, the rubber bushing 15 is deformed into an arc shape after being squeezed by the first extrusion piece 3 and the second extrusion piece 4, which greatly reduces the obstruction to the fluid passing through the rubber bushing 15 and makes the fluid flow more smoothly.

[0051] Therefore, the Internet of Things balancing valve according to the embodiment of the present invention has the advantages of low impedance and stable flow rate and flow regulation.

[0052] In some embodiments, the first extrusion member 3 has a first contact surface 31 on the side facing the second extrusion member 4, and the first contact surface 31 is an arc-shaped surface protruding toward the second extrusion member 4; the second extrusion member 4 has a second contact surface 41 on the side facing the first extrusion member 3, and the second contact surface 41 is an arc-shaped surface protruding toward the first extrusion member 3.

[0053] Specifically, Figure 1 and Figure 2 As shown, the first contact surface 31 is provided on the lower side of the first extrusion member 3, and the first contact surface 31 bulges downward to form an arcuate surface. The second contact surface 41 is provided on the upper side of the second extrusion member 4, and the second contact surface 41 bulges upward to form an arcuate surface.

[0054] It can be understood that when the first extrusion member 3 and the second extrusion member 4 extrude the rubber bushing 15, the first contact surface 31 and the second contact surface 41 are in contact with the rubber bushing 15. Since the first contact surface 31 and the second contact surface 41 are both arc-shaped surfaces, scratches on the rubber bushing 15 can be avoided, thereby increasing the service life of the rubber bushing 15.

[0055] In some embodiments, the Internet of Things balancing valve of the embodiment of the present invention also includes a fixing member 5, which is penetrated on the mounting portion 11 along the second direction, at least part of the fixing member 5 is located in the mounting cavity 113, the fixing member 5 has a fixing cavity 52, the first extrusion member 3 is located in the fixing cavity 52, a part of the second extrusion member 4 is located in the fixing cavity 52, and the first end and the second end of the second extrusion member 4 are located outside the fixing cavity 52.

[0056] Specifically, Figure 2 and Figure 3 As shown, the lower part of the fixing member 5 is arranged in the mounting cavity 113 and is connected to the mounting portion 11, the left end of the second extrusion member 4 forms the first end of the second extrusion member 4, and the right end of the second extrusion member 4 forms the second section of the second extrusion member 4, and the middle part of the second extrusion member 4 is located in the fixing cavity 52.

[0057] In some embodiments, the Internet of Things balancing valve of the embodiment of the present invention also includes a first connecting rope 61 and a second connecting rope 62, wherein the first end of the first connecting rope 61 is connected to the first end of the first extrusion member 3, the second end of the first connecting rope 61 is connected to the first end of the second extrusion member 4, the first end of the second connecting rope 62 is connected to the second end of the first extrusion member 3, and the second end of the second connecting rope 62 is connected to the second end of the second extrusion member 4.

[0058] Specifically, Figure 2 and Figure 3 As shown, the upper end of the first connecting rope 61 is the first end of the first connecting rope 61, the lower end of the first connecting rope 61 is the second end of the first connecting rope 61, and the left end of the first extruded member 3 is the first end of the first extruded member 3. The upper end of the second connecting rope 62 is the first end of the second connecting rope 62, the lower end of the second connecting rope 62 is the second end of the second connecting rope 62, and the right end of the first extruded member 3 is the second end of the first extruded member 3.

[0059] It can be understood that the upper end of the first connecting rope 61 is located in the fixed cavity 52 and connected to the left end of the first extrusion member 3, and the lower end of the first connecting rope 61 is located outside the fixed cavity 52 and connected to the left end of the second extrusion member 4; the upper end of the second connecting rope 62 is located in the fixed cavity 52 and connected to the right end of the first extrusion member 3, and the lower end of the second connecting rope 62 is located outside the fixed cavity 52 and connected to the right end of the second extrusion member 4.

[0060] That is to say, when the first extrusion component 3 is forced to move downward, the second extrusion component 4 will move toward the direction of the first extrusion component 3 (i.e., move upward) through the first connecting rope 61 and the second connecting rope 62. At this time, the first extrusion component 3 and the second extrusion component 4 move toward each other, and the rubber bushing 15 is located between the first extrusion component 3 and the second extrusion component 4. Therefore, when the first extrusion component 3 moves downward, the first extrusion component 3 and the second extrusion component 4 will squeeze the rubber bushing 15.

[0061] Preferably, if Figure 4 and Figure 5 As shown, in the initial state (i.e., the first extrusion component 3 and the second extrusion component 4 do not extrude the rubber bushing 15), the first contact surface 31 and the second contact surface 41 are both in contact with the outer peripheral surface of the rubber bushing 15. Then, when the first extrusion component 3 moves, the second extrusion component 4 will be driven to move simultaneously through the first connecting rope 61 and the second connecting rope 62.

[0062] Preferably, the fixing member 5 includes a first fixing rod 51 and a second fixing rod 52, the first fixing rod 51 and the second fixing rod 52 are arranged at intervals, a fixing cavity 52 is formed between the first fixing rod 51 and the second fixing rod 52, a first through hole 511 is provided on the first fixing rod 51, a second through hole 521 is provided on the second fixing rod 52, a first end of the first connecting rope 61 extends into the fixing cavity 52 through the first through hole 511 and is connected to the first end of the first extruded member 3, and a first end of the second connecting rope 62 extends into the fixing cavity 52 through the second through hole 521 and is connected to the second end of the first extruded member 3.

[0063] Specifically, Figure 2 As shown, the first fixing rod 51 and the second fixing rod 52 are arranged at intervals in the front-to-back direction, and the axis extension direction of the first through hole 511 and the axis extension direction of the second through hole 521 are consistent with the front-to-back direction.

[0064] It can be understood that the second extrusion member 4 is provided with a first fixing hole matching the first fixing rod 51 and a second fixing hole matching the second fixing rod 52. The second extrusion member 4 cooperates with the first fixing rod 51 and the second fixing rod 52 through the first fixing hole and the second fixing hole respectively, so that the second extrusion member 4 moves in the up and down directions.

[0065] In some embodiments, the Internet of Things balancing valve of the embodiment of the present invention also includes a first guide member 7 and a second guide member 8, the first guide member 7 includes a first guide wheel 71 and a first support rod 72, one end of the first support rod 72 is connected to the first fixing member 5, and the other end of the first support rod 72 extends in a direction away from the first fixing member 5, the first guide wheel 71 is arranged at the other end of the first support rod 72 and can rotate around the first direction, the first support rod 72 is located between the first extrusion member 3 and the second extrusion member 4 in the second direction, and the first connecting rope 61 is wrapped around the first guide wheel 71; the second guide member 8 includes a second guide wheel 81 and a second support rod 82, one end of the second support rod 82 is connected to the second fixing member 5, and the other end of the second support rod 82 extends in a direction away from the second fixing member 5, the second guide wheel 81 is arranged at the other end of the second support rod 82 and can rotate around the first direction, the second support rod 82 is located between the first extrusion member 3 and the second extrusion member 4 in the second direction, and the second connecting rope 62 is wrapped around the second guide wheel 81.

[0066] Specifically, Figure 2 and Figure 3 As shown, one of the first guide wheel 71 and the first support rod 72 is provided with a rotating shaft, and the other of the first guide wheel 71 and the first support rod 72 is provided with an axial hole matching the rotating shaft, and the first guide wheel 71 and the first support rod 72 cooperate with each other through the rotating shaft and the axial hole, so that the first guide wheel 71 rotates in the left-right direction. Similarly, the second guide wheel 81 and the second support rod 82 can also cooperate with each other through the rotating shaft and the axial hole, so that the second guide wheel 81 rotates in the left-right direction.

[0067] It can be understood that the upper end of the first connecting rope 61 first bypasses the first guide wheel 71, passes through the first through hole 511, extends into the fixed cavity 52, and is connected to the left end of the first extrusion member 3, and the first connecting rope 61 contacts the outer peripheral surface of the first guide wheel 71 to achieve a guiding effect. In addition, preferably, the first guide wheel 71 is located below the first through hole 511, so that after the first connecting rope 61 bypasses the first guide wheel 71, it passes through the first through hole 511 in a state parallel to the left and right directions.

[0068] Similarly, the upper end of the second connecting rope 62 first passes around the second guide wheel 81, then passes through the second through hole 521 and extends into the fixed cavity 52 to be connected to the right end of the first extrusion member 3, and the second connecting rope 62 contacts the outer peripheral surface of the second guide wheel 81 to achieve a guiding effect. In addition, preferably, the first guide wheel 71 is located below the first through hole 511.

[0069] In some embodiments, the Internet of Things balancing valve of the embodiment of the present invention also includes a control unit 9, which is connected to the installation unit 11. The control unit 9 includes a drive component 91, and the drive component 91 includes a drive shaft 92. The drive shaft 92 is connected to the first extrusion component 3 so as to drive the first extrusion component 3 to move toward the second extrusion component 4.

[0070] Specifically, Figure 1 and Figure 2 As shown, the control part 9 is connected to the upper end of the fixing member 5 so as to fix the control part 9, and the driving shaft 92 of the starting assembly is connected to the first extrusion member 3 for driving the first extrusion member 3 to move.

[0071] It can be understood that the driving component 91 can be a telescopic motor, and the output shaft of the telescopic motor is the driving shaft 92. When the telescopic motor is started, the output shaft of the telescopic motor can drive the first extrusion member 3 to move.

[0072] Preferably, the driving assembly 91 is a screw module, the driving shaft 92 is a screw, and the screw nut is arranged on the first extrusion member 3, so that the driving shaft 92 rotates to drive the screw nut to move.

[0073] It should be noted that the driving assembly 91 can be driven by a private servo motor to ensure the movement accuracy of the first extrusion member 3.

[0074] In some embodiments, the IoT balancing valve of the embodiment of the present invention further includes a detection member, which is disposed in the first connecting pipe 12 and / or the second connecting pipe 13, and is electrically connected to the driving assembly 91, and is used to detect the flow rate and temperature of the fluid passing through the first connecting pipe 12 and the second connecting pipe 13. It is understandable that the detection member may be a temperature sensor and a flow sensor, and the temperature sensor and the flow sensor may be disposed in the first connecting pipe 12 and the second connecting pipe 13, respectively, or the temperature sensor and the flow sensor may be disposed in the first connecting pipe 12, or the temperature sensor and the flow sensor may be disposed in the second connecting pipe 13.

[0075] When the fluid flow and temperature in the valve body 1 reach the first preset flow value and the first preset temperature value of the detection member respectively, the drive component 91 drives the drive shaft 92 to move, and the first extrusion member 3 and the second extrusion member 4 move relative to each other, so that the rubber bushing 15 is in an extruded state. When the fluid flow and temperature in the valve body 1 reach the second preset flow value and the second preset temperature value of the detection member respectively, the drive component 91 drives the drive shaft 92 to move, so that the first extrusion member 3 and the second extrusion member 4 move toward each other, so that the rubber bushing 15 returns to its original state, wherein the first preset flow value is less than the second preset flow value, and the first preset temperature value is less than the second preset temperature value.

[0076] In some embodiments, the first connecting tube 12 includes a first flange 121, which is disposed at one end of the first connecting tube 12 away from the mounting portion 11, the second connecting tube 13 includes a second flange 131, which is disposed at one end of the second connecting tube 13 away from the mounting portion 11, the rubber bushing 15 includes a third flange 21 and a fourth flange 22, the third flange 21 is disposed at the first end of the rubber bushing 15 and connected to the first flange 121, and the fourth flange 22 is disposed at the second end of the rubber bushing 15 and connected to the second flange 131.

[0077] Specifically, Figure 1 , Figure 4 and Figure 5 As shown, the first flange 121 is arranged at the left end of the first connecting pipe 12 , the second flange 131 is arranged at the right end of the second connecting pipe 13 , the third flange 21 is arranged at the left end of the rubber bushing 15 , and the fourth flange 22 is arranged at the right end of the rubber bushing 15 .

[0078] It is understandable that the third flange 21 and the first flange 121 can be connected by a connecting member, for example, the first flange 121 is provided with a plurality of first connecting holes, the plurality of first connecting holes are arranged at intervals along the circumference of the first flange 121, the third flange 21 is provided with second connecting holes corresponding to the plurality of first connecting holes one by one, and the first connecting holes and the second connecting holes can be connected by connecting members such as screws or bolts, so that the first flange 121 and the third flange 21 are connected. Similarly, the second flange 131 and the fourth flange 22 can also be connected by a connecting member.

[0079] In some embodiments, the IoT balancing valve of the embodiment of the present invention further includes an elastic member 100 , which is disposed in the mounting cavity 113 and connected between the second extrusion member 4 and the mounting portion 11 in the second direction.

[0080] Specifically, Figure 2 , Figure 4 and Figure 5 As shown, the elastic member 100 is disposed between the bottom wall of the mounting portion 11 and the second extrusion member 4. It should be noted that the elastic member 100 may be a spring, a spring sheet or other elastic components.

[0081] Preferably, if Figure 2 As shown, the elastic member 100 is a spring. When the first extrusion member 3 and the second extrusion member 4 are in the initial state, the elastic member 100 is not subjected to force. Then, when the first extrusion member 3 and the second extrusion member 4 move toward each other, the second extrusion member 4 overcomes the pulling force of the elastic member 100 and moves upward. At this time, the elastic member 100 is stretched under force.
