Abstract
Description
Technical Field
[0001] This application relates to the field of valve technology, and more particularly to a microbubble valve. Background Technology
[0002] Tiny bubbles exist in the fluid medium of systems such as heat pumps, refrigeration cycles, and ground source heat pumps. Tiny bubbles can easily lead to problems such as cavitation, uneven flow, or reduced thermal efficiency. Microbubble valves are usually used to remove tiny bubbles from the fluid medium.
[0003] In related technologies, the internal float of traditional microbubble valves has insufficient stability, which can easily cause it to deviate, get stuck or vibrate under liquid turbulence or bubble impact, thus affecting its response sensitivity to bubbles.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0053] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.
[0054] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.
[0055] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0056] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.
[0057] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).
[0058] In modern industrial and civil applications, heat pumps, refrigeration cycles, and ground source heat pumps are widely used due to their high efficiency and energy savings. During operation, these systems often contain tiny air bubbles in the fluid medium. The cavitation phenomenon caused by these bubbles can corrode and damage metal components within the system, shortening equipment lifespan. The presence of bubbles can also disrupt normal fluid flow, leading to uneven flow and affecting stable system operation. Furthermore, bubbles can form an air film on heat exchange surfaces, hindering heat transfer and significantly reducing thermal efficiency, thus increasing energy costs.
[0059] To address the problems caused by tiny bubbles in refrigerants or liquids, microbubble valves are typically used to remove these bubbles. However, most microbubble valves in related technologies employ a split-type structure. This design not only complicates the manufacturing process due to the processing and assembly of multiple components, increasing labor and material costs, but also results in a larger overall size and poorer sealing performance. Furthermore, traditional microbubble valves suffer from insufficient stability in the movement of the internal float, making them prone to displacement, jamming, or vibration under liquid turbulence or bubble impacts. This affects their sensitivity to bubble responses, and this instability can lead to delayed or failed exhaust control, especially in low-flow or high-bubble-concentration scenarios, where the reliability of microbubble valves decreases significantly.
[0060] Based on this, this application proposes a microbubble valve 100, which uses guide post 4 to guide the movement of float body 51, thereby improving the stability of float body 51 when it moves along the axial direction X of valve body, avoiding displacement, jamming or vibration caused by collision between float body 51 and valve body 1, thereby improving the response sensitivity of microbubble valve 100 to bubbles, avoiding exhaust delay or failure, and improving the reliability of microbubble valve 100.
[0061] The microbubble valve 100 proposed in this application is described below with reference to the accompanying drawings.
[0062] like Figures 1-6As shown, the microbubble valve 100 according to an embodiment of this application includes: a valve body 1, a filter screen 2, a valve cover 3, a guide post 4, and a float assembly 5. The valve body 1 has a receiving cavity 11, one end of which is open to form a valve cover opening 111. The valve body 1 is provided with a first inlet / outlet 12 and a second inlet / outlet 13 respectively communicating with the receiving cavity 11. The filter screen 2 is disposed in the receiving cavity 11, at least a portion of which is located between the first inlet / outlet 12 and the second inlet / outlet 13. The valve cover 3 is disposed on the valve body 1 to seal the valve cover opening 111, and the valve cover 3 is provided with an exhaust port 31. The guide post 4 is located on the side of the valve cover 3 facing the receiving cavity 11, and the guide post 4 extends along the axial direction X of the valve body. The float assembly 5 includes a float body 51 and a first sealing rod 52 connected by a drive. The float body 51 is located in the receiving cavity 11 and has a guide channel 511 that is fitted with the guide post 4. The guide channel 511 extends along the axial direction X of the valve body. The guide engagement between the guide post 4 and the guide channel 511 allows the float body 51 to move relative to the guide post 4. The float body 51 is adapted to drive the first sealing rod 52 to selectively block the exhaust port 31.
[0063] Specifically, the valve cover 3 is detachably mounted on the valve cover opening 111, and the valve cover 3 is provided with an exhaust port 31, such as... Figure 3 As shown, an exhaust cap 10 is provided at the exhaust port 31, and a support seat 9 is provided inside the exhaust port 31. One end of the first sealing rod 52 extends into the exhaust port 31, and the support seat 9 is fixedly connected to the first sealing rod 52. Along the axial direction X of the valve body, the spring 8 is abutted between the support seat 9 and the valve cover 3. The float body 51 is connected to the first sealing rod 52 through a transmission connection. It can be understood that the float body 51 can be directly connected to the first sealing rod 52 through a transmission connection, or it can be indirectly connected through other components.
[0064] When liquid flows into the receiving cavity 11 from the first inlet / outlet 12 or the second inlet / outlet 13, the gas in the liquid can be filtered by the filter screen 2 because at least part of the filter screen 2 is located between the first inlet / outlet 12 and the second inlet / outlet 13. It can be understood that the mesh structure of the filter screen 2 increases the gas-liquid contact area. When the liquid passes through the filter screen 2, the filter screen 2 can promote the coalescence of small bubbles in the liquid (small bubbles merge into large bubbles), improving the separation efficiency. When the large bubbles merge together, they can become air. Then the air rises under the action of buoyancy, causing the air to accumulate at the upper end of the receiving cavity 11. Subsequently, the air pushes the liquid level down. Along the axial direction X of the valve body, the air pushes the float body 51 to move toward the end away from the valve cover 3. Continuing to refer to Figure 2, the float body 51 is connected to the first sealing rod 52. The float body 51 can drive the first sealing rod 52 to move along the axial direction X of the valve body and toward the direction away from the exhaust port 31, so that the gas can be discharged from the exhaust port 31. When the microbubble valve 100 does not release air, the first sealing rod 52 blocks the exhaust port 31 under the action of the spring 8.
[0065] For example, such as Figure 4 As shown, the first sealing rod 52 includes a sealing part 521, and a sealing ring 7 is provided between the sealing part 521 and the vent 31. The sealing part 521 has an arc surface, which abuts against the sealing ring 7, thereby sealing the vent 31 when no vent is released. The sealing performance can be improved by the cooperation of the sealing ring 7 and the sealing part 521.
[0066] Furthermore, the guide post 4 is disposed on the side of the valve cover 3 facing the receiving cavity 11, and the guide post 4 extends along the axial direction X of the valve body. The float body 51 has a guide channel 511 that is fitted with the guide post 4. The guide post 4 can be inserted into the guide channel 511. The guide post 4 can guide and limit the float body 51. This can ensure the stability of the float body 51 when it moves along the axial direction X of the valve body, and avoid the float body 51 from deflecting, jamming or vibrating due to collision with the valve body 1. This improves the response sensitivity of the microbubble valve 100 to bubbles, avoids exhaust delay or failure, and helps to improve the reliability of the microbubble valve 100.
[0067] In summary, the microbubble valve 100 proposed in the embodiments of this application guides the movement of the float body 51 using the guide post 4, thereby improving the stability of the float body 51 when it moves along the axial direction X of the valve body. This prevents the float body 51 from deviating, jamming, or vibrating due to collision with the valve body 1, thereby improving the response sensitivity of the microbubble valve 100 to bubbles and avoiding exhaust delay or failure. This is beneficial to improving the reliability of the microbubble valve 100. At the same time, the valve body 1 is constructed as an integral molded part, which can further reduce the risk of liquid leakage, thereby further improving the sealing performance of the microbubble valve 100.
[0068] In some embodiments of this application, as shown in the figure, the guide post 4 includes a guide body 41 and a limiting part 42. The guide body 41 is fixedly connected to the valve cover 3. The guide body 41 extends along the axial direction X of the valve body and is assembled with the guide channel 511. Along the axial direction X of the valve body, the limiting part 42 is provided at one end of the guide body 41 away from the valve cover 3. The float body 51 is provided between the guide body 41 and the limiting part 42. Along the axial direction X of the valve body, the limiting part 42 restricts the float body 51 from moving in the direction away from the valve cover 3.
[0069] Specifically, the guide post 4 consists of a guide body 41 and a limiting part 42. The guide body 41 is fixedly installed on the side of the valve cover 3 facing the receiving cavity 11. Along the axial direction X of the valve body, the limiting part 42 is located at the end of the guide body 41 away from the valve cover 3. Along the axial direction X of the valve body, the limiting part 42 limits the downward movement distance of the float body 51. By limiting the downward movement position of the float body 51 through the limiting part 42, the structure is simple and effective. Of course, the lower displacement position of the float body 51 can also be limited by other structures, such as the upper end face of the filter screen 2.
[0070] In this design, the float body 51 is fixed to the guide body 41 by sliding up and down through the guide channel 511, which makes the movement of the float body 51 highly controllable and prevents the problem of displacement or twisting caused by water flow or air impact, thus greatly enhancing the stability of the movement of the float body 51.
[0071] In some embodiments of this application, such as Figure 2 As shown, the valve cover 3 is provided with a first protrusion 32, which is located on the side of the valve cover 3 facing the receiving cavity 11. The guide post 4 has a mounting cavity, and the guide post 4 is inserted into the first protrusion 32 through the mounting cavity. This arrangement facilitates the installation of the guide post 4 and the valve cover 3 and helps to improve installation efficiency.
[0072] In some embodiments of this application, such as Figure 2 and Figure 5As shown, a mounting sleeve 33 is provided on the valve cover 3. The mounting sleeve 33 is located on the side of the valve cover 3 facing the receiving cavity 11. The mounting sleeve 33 surrounds a mounting chamber 34 that communicates with the exhaust port 31. A portion of the first sealing rod 52 can be selectively moved into the mounting chamber 34 to block the exhaust port 31. The microbubble valve 100 also includes a fixing member 6. The fixing member 6 includes a first fixing part 61, a first elastic part 62, and a second fixing part 63 connected in sequence. The first fixing part 61 is engaged with the first protrusion. 32, and along the axial direction X of the valve body, the first fixing part 61 is disposed between the guide post 4 and the valve cover 3, the second fixing part 63 is sleeved on the mounting sleeve 33, the first elastic part 62 is configured to press the second fixing part 63 against the side of the valve cover 3 facing the receiving cavity 11, the float assembly 5 also includes a connecting rod 53, the connecting rod 53 is rotatably disposed on the second fixing part 63, the float body 51 is adapted to drive the connecting rod 53 to rotate, so that the connecting rod 53 drives the first sealing rod 52 to selectively block the exhaust port 31.
[0073] Specifically, along the axial direction X of the valve body, the mounting sleeve 33 is set on the lower end face of the valve cover 3. The mounting sleeve 33 surrounds the mounting chamber 34 which communicates with the exhaust port 31. The mounting chamber 34 is provided with a sealing ring 7. A portion of the sealing part 521 of the first sealing rod 52 can be selectively moved into the mounting chamber 34 so that the sealing part 521 abuts against the sealing ring 7, thereby sealing the exhaust port 31 when no exhaust is emitted.
[0074] The second fixing part 63 may be provided with a mounting hole, which is fitted onto the mounting sleeve 33. When assembling the fixing part 6, the second fixing part 63 can be fitted onto the mounting sleeve 33 first, and then the first fixing part 61 can be snapped onto the first protrusion 32. The snap-fit installation method facilitates the assembly of the fixing part 6 and the valve cover 3.
[0075] The first fixing part 61 can fix the fixing member 6 to the valve cover 3, and the first elastic member can press the second fixing part 63 to the side of the valve cover 3 facing the receiving cavity 11. In this way, both the first fixing part 61 and the second fixing part 63 can be fixed to the valve cover 3. The float assembly 5 also includes a connecting rod 53, which is rotatably disposed on the second fixing part 63.
[0076] Furthermore, the float body 51 is connected to the connecting rod 53, and the connecting rod 53 abuts against the abutting part 522 of the first sealing rod 52. The second fixing part 63 also provides a rotation fulcrum for the connecting rod 53. When air can push the float body 51 to move away from the valve cover 3, the connecting rod 53 rotates around the second fixing part 63 under the drive of the float body 51. During the rotation of the connecting rod 53, it drives the first sealing rod 52 to move along the axial direction X of the valve body and away from the exhaust port 31, so that gas can be discharged from the exhaust port 31. The entire driving method is simple and reliable.
[0077] In some embodiments of this application, such as Figure 5 As shown, the second fixing part 63 includes a second body 631 and a fixing piece 632. The second body 631 is connected to the first elastic part 62. The fixing piece 632 is disposed on the second body 631 and extends in a direction away from the valve cover 3. The second fixing part 63 is sleeved on the mounting sleeve 33. The connecting rod 53 is rotatably disposed on the fixing piece 632.
[0078] Along the axial direction X of the valve body, the fixing plate 632 extends in the direction away from the valve cover 3, so that the second body 631 and the fixing plate 632 together form a cantilever structure. The fixing plate 632 can be provided with corresponding shaft holes or pin holes, and the connecting rod 53 can be inserted into the corresponding shaft holes or pin holes on the fixing plate 632. The connecting rod 53 is rotatably set in the corresponding shaft holes or pin holes, thereby driving the first sealing rod 52 to block or open the exhaust port 31.
[0079] The fixed plate 632 provides a pivot point for the connecting rod 53, which ensures that the connecting rod 53 can rotate in a plane around the corresponding pivot point of the fixed plate 632, thus avoiding the skewing of the sealing rod due to the multi-dimensional movement of the connecting rod 53 and ensuring the normal operation of the microbubble valve 100.
[0080] In some embodiments of this application, such as Figure 1 As shown, along the axial direction X of the valve body, the valve cover 3 and the second inlet / outlet 13 are located on both sides of the filter screen 2. That is, the exhaust port 31 is arranged opposite to the second inlet / outlet 13 along the axial direction X of the valve body, and the valve cover 3 and the second inlet / outlet 13 are located on both sides of the filter screen 2. This facilitates the separation and floating of microbubbles, which is beneficial to improving the exhaust efficiency of the microbubble valve 100.
[0081] In some embodiments of this application, the valve body 1 is a one-piece molded part. That is, the valve body 1 is constructed as a one-piece molded part. This one-piece molding process can avoid the risk of liquid leakage caused by the seams of the splicing of the split valve body 1, which is beneficial to further improve the sealing performance of the microbubble valve 100.
[0082] For example, the material of valve body 1 can be stainless steel, engineering plastics, or other corrosion-resistant materials. Moreover, valve body 1 is constructed as a one-piece molded part. Compared to a split valve body 1, there is no need to set up additional connecting structures to connect valve body 1, which reduces the space occupied inside valve body 1 and helps to improve the utilization rate of internal space of valve body 1.
[0083] In some embodiments of this application, the first inlet / outlet 12 and the second inlet / outlet 13 are spaced apart along the axial direction X of the valve body. That is, the first inlet / outlet 12 and the second inlet / outlet 13 are spaced apart along the axial direction X of the valve body. Since at least a portion of the filter screen 2 is located between the first inlet / outlet 12 and the second inlet / outlet 13, at least a portion of the filter screen 2 extends along the axial direction X of the valve body, thereby increasing the microbubble rising rate and making the microbubble aggregation more sufficient, which is beneficial to further improving the exhaust efficiency of the microbubble valve 100.
[0084] In some embodiments of this application, such as Figure 1 As shown, the valve body 1 also includes a bottom wall 14 and a peripheral wall 15. The peripheral wall 15 is disposed on the outer periphery of the bottom wall 14 along the axial direction X of the valve body. The bottom wall 14 is disposed opposite to the valve cover opening 111. The second liquid inlet / outlet 13 is disposed on the bottom wall 14, and the first liquid inlet / outlet 12 is disposed on the peripheral wall 15.
[0085] Liquid enters the receiving cavity 11 through the first inlet / outlet 12 located on the peripheral wall 15, and then exits the receiving cavity 11 through the second inlet / outlet 13 located on the bottom wall 14. For example, the axial direction X of the valve body can be parallel to the vertical direction. The height of the first inlet / outlet 12 is higher than that of the second inlet / outlet 13. After entering the first inlet / outlet 12, the liquid will not directly impact the second inlet / outlet 13. The flow direction of the liquid within the receiving cavity 11 changes, the liquid velocity decreases, and the liquid can be filtered more thoroughly by the filter screen 2. The filter screen 2 can more effectively merge the tiny bubbles in the liquid, improving the working performance of the microbubble valve 100.
[0086] In some embodiments of this application, one of the first inlet / outlet 12 and the second inlet / outlet 13 is an inlet, and the other is an outlet. That is, when the first inlet / outlet 12 is set as an inlet, the second inlet / outlet 13 is set as an outlet, and when the first inlet / outlet 12 is set as an outlet, the second inlet / outlet 13 is set as an inlet. This allows liquid to flow into the receiving cavity 11 from the first inlet / outlet 12 and out from the second inlet / outlet 13, or vice versa, improving the versatility of the microbubble valve 100.
[0087] In some embodiments of this application, the first inlet / outlet 12 and the second inlet / outlet 13 are arranged opposite to each other along the radial direction of the valve body 1. That is, the first inlet / outlet 12 and the second inlet / outlet 13 can be arranged opposite to each other along the radial direction of the valve body 1, which makes the liquid flow smoother.
[0088] In some embodiments of this application, such as Figure 1As shown, the microbubble valve 100 also includes a pressure relief port 16 disposed on the valve body 1. The pressure relief port 16 is connected to the receiving cavity 11. Along the axial direction X of the valve body, the pressure relief port 16 is located between the first inlet / outlet port 12 and the second inlet / outlet port 13.
[0089] When the pressure of the liquid inside the receiving cavity 11 is too high, the abnormal pressure in the receiving cavity 11 can be released through the pressure relief port 16, ensuring the safe and stable operation of the microbubble valve 100. A pressure relief valve can be installed on the pressure relief port 16. When it is necessary to release the pressure inside the microbubble valve 100, the pressure relief valve can be opened to release the internal pressure of the microbubble valve 100. Along the axial direction X of the valve body, the pressure relief port 16 is located between the first inlet / outlet port 12 and the second inlet / outlet port 13. This ensures that when the liquid pressure inside the receiving cavity 11 is too high, the liquid can be relieved through the pressure relief port 16.
[0090] In some embodiments of this application, such as Figure 1 As shown, the microbubble valve 100 also includes a spare valve port 17, which is connected to the receiving cavity 11. Along the axial direction X of the valve body, the pressure relief port 16 is spaced apart from the spare valve port 17.
[0091] Along the axial direction X of the valve body, a backup valve port 17 can be located between the first inlet / outlet port 12 and the second inlet / outlet port 13. For example, the backup valve port 17 can be used to connect a bypass. If the main pipeline at the second inlet / outlet port 13 fails and requires repair, the backup valve port 17 can be connected to the bypass to maintain continuous system operation. The backup valve port 17 can also be reserved for future functional expansion; for example, it can be connected to a chemical injection device, avoiding a redesign of the valve body 1 structure and reducing modification costs. When the backup valve port 17 is not in use, it can be sealed with a plug. In the event of a failure in the pressure relief port 16, the backup valve port 17 can replace the pressure relief port 16 to relieve pressure in the receiving cavity 11.
[0092] In some embodiments of this application, such as Figure 1 and Figure 6 As shown, the filter screen 2 includes: multiple first rings 21, multiple first rod groups, and multiple connecting plates 23. Along the axial direction X of the valve body, the multiple first rings 21 are spaced apart. Each first rod group is located radially inside the corresponding first ring 21. Each first rod group includes multiple first rods 221. Each first rod 221 extends radially along the first ring 21. The multiple first rods 221 are spaced apart circumferentially along the first ring 21. Along the circumferential direction of the first ring 21, multiple connecting plates 23 are spaced apart. Along the axial direction X of the valve body, each connecting plate 23 connects multiple first rings 21. Each connecting plate 23 is provided with multiple spaced second rods 231. The multiple second rods 231 are located radially inside the first ring 21 and extend radially along the first ring 21.
[0093] Along the axial direction X of the valve body, each second rod 231 is disposed between two adjacent first rings 21. Along the axial direction X of the valve body, the projections of the first rod 221 and the second rod 231 do not coincide, which can improve the filtration performance of the filter screen 2. For example, both the first rod 221 and the second rod 231 can be constructed as needle-like structures.
[0094] Along the axial direction X of the valve body, multiple first rings 21 are spaced apart, and multiple second rods 231 are spaced apart. This forms a multi-layer filtration barrier, extends the filtration path, and enables the filter screen 2 to merge more micro bubbles into large bubbles, thereby improving the filtration performance of the filter screen 2.
