Description

Technical Field

[0001] This application relates to the field of pipeline technology, and more particularly to a scale inhibitor valve. Background Technology

[0002] Tap water often contains a large number of impurities, such as rust, calcium and magnesium ions. During the use of gas wall-hung boilers, water heaters, pure water machines, water purifiers and other equipment, scale is easily generated in the pipes and equipment. Scale will deposit in the pipes, causing blockage and affecting the normal operation of the equipment. Utility Model Content

[0003] This application provides a scale inhibitor valve that can reduce scale buildup.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include:

[0005] This application provides a scale-inhibiting valve, including a valve body, a scale-inhibiting part, a shielding part, and a plug. The valve body has a main channel. The scale-inhibiting part is disposed on one side of the valve body and has a scale-inhibiting channel for placing a scale-inhibiting plate. The scale-inhibiting channel is angled to the main channel. Along the axial direction of the scale-inhibiting channel, the scale-inhibiting channel has a first opening and a second opening disposed opposite to each other. The first opening is connected to the main channel. The shielding part is at least partially disposed in the scale-inhibiting channel to separate the scale-inhibiting plate from the main channel. The shielding part has multiple through holes to connect the main channel and the scale-inhibiting channel. The plug is detachably disposed in the scale-inhibiting part to block the second opening.

[0006] The scale inhibitor valve proposed in this application has a detachable plug located in the scale inhibitor section, and a shielding section at least partially located in the scale inhibitor channel. The plug, scale inhibitor section, and shielding section together form a receiving cavity for accommodating the scale inhibitor sheet. The shielding section has multiple through holes to allow water in the main channel to flow into the scale inhibitor channel. The water entering the scale inhibitor channel comes into full contact with the scale inhibitor sheet, allowing the scale inhibitor sheet to dissolve well in the water, thereby removing scale components from the water, improving water quality, enhancing water safety, reducing scale deposition in pipes, improving equipment efficiency, and extending equipment service life.

[0007] In addition, the scale inhibitor is located on one side of the valve body, and the scale inhibitor plate in the scale inhibitor channel is located on one side of the main channel. This can reduce the impact of water in the main channel on the scale inhibitor plate, thereby reducing the dissolution rate of the scale inhibitor plate. Furthermore, the scale inhibitor channel and the scale inhibitor plate are located on one side of the main channel, which can reduce the impact of the scale inhibitor plate on the flow rate of the main channel.

[0008] Optionally, the angle between the axis of the main channel and the axis of the scale-inhibiting channel is α, satisfying: 0° < α < 90°.

[0009] In the above scheme, the scale inhibition channel is inclined on the main channel, which allows the scale inhibition plate dissolved in the scale inhibition channel to better enter the main channel through the through hole of the shielding part, so that the scale inhibition plate can fully react with the metal ions in the water.

[0010] Optionally, along the axial direction of the main channel, the main channel has an inlet and an outlet that are disposed opposite to each other, and the scale-inhibiting channel is inclined toward the inlet.

[0011] In the above scheme, the scale inhibition channel is inclined towards the water inlet, which makes it easier for the dissolved scale inhibitor to flow into the main channel under the combined action of gravity and water flow, thereby improving the effect of the scale inhibitor.

[0012] Optionally, the axis of the main channel is perpendicular to the axis of the scale-inhibiting channel.

[0013] In the above scheme, the scale inhibition channel is set perpendicular to the main channel, which makes it easier for the water in the main channel to enter the scale inhibition channel. The water flow has a better dissolving effect on the scale inhibition plate, thereby improving the effect of the scale inhibition plate.

[0014] Optionally, the scale-inhibiting channel includes a first segment and a second segment connected together. The first opening is located at the end of the first segment away from the second segment, and the second opening is located at the end of the second segment away from the first segment. The inner diameter of the first segment is smaller than the inner diameter of the second segment to form a first stepped surface, and the shielding portion abuts against the first stepped surface.

[0015] In the above scheme, the shielding part abuts against the first step surface, so that the shielding part can be kept in the scale inhibition channel and will not enter the main channel due to the action of water flow, thereby enabling the shielding part to shield the scale inhibition plate in the scale inhibition channel.

[0016] Optionally, the second segment has a third opening communicating with the main channel.

[0017] In the above scheme, the third opening diverts the water in the main channel and increases the amount of water entering the scale-inhibiting channel, so that the scale-inhibiting plate can fully interact with the ions in the water.

[0018] Optionally, the scale inhibitor valve further includes a first housing, which is connected to the shielding portion. The first housing is disposed in the second section, and the first housing, the shielding portion, and the plug together form a receiving cavity for accommodating the scale inhibitor plate.

[0019] In the above solution, the first housing can fix the shielding part, reduce the movement of the shielding part due to the water flow, and the first housing can also fix the scale inhibitor sheet.

[0020] Optionally, the scale inhibition valve further includes a filter screen disposed in the main channel, the filter screen being connected to the shielding part, the filter screen being constructed as a ring structure, and the axis of the filter screen being perpendicular to the axis of the main channel.

[0021] In the above scheme, the filter screen is installed in the main channel to filter the water in the main channel and remove impurities from the water. The filter screen is connected to the shielding part and can be removed from the scale-inhibiting channel to achieve the purpose of replacing or cleaning the filter screen.

[0022] Optionally, a protrusion is provided on the inner wall of the main channel. Along the axial direction of the scale-inhibiting channel, the protrusion is disposed opposite to the shielding part, and the end of the filter screen away from the shielding part overlaps and cooperates with the protrusion.

[0023] In the above solution, the end of the filter screen away from the shield is fitted onto the protrusion to fix the filter screen and reduce the chance of the filter screen shifting due to water flow impact.

[0024] Optionally, along the axial direction of the main channel, a fourth opening is provided on one side of the filter screen; along the axial direction of the main channel, the main channel has an inlet and an outlet disposed opposite to each other, and the fourth opening faces the inlet.

[0025] In the above scheme, the fourth opening faces the water inlet, which can achieve water filtration in the main channel while reducing the restriction of the filter screen on the water flow in the main channel.

[0026] Optionally, the scale inhibitor valve further includes a second housing, which is disposed within the scale inhibitor channel and connected to the shielding portion. The plug, the second housing, and the shielding portion together form a receiving cavity for accommodating the scale inhibitor sheet. The second housing, the shielding portion, and the filter screen are integrally molded.

[0027] In the above solution, when the filter screen or shielding part needs to be cleaned or replaced, the second housing, along with the filter screen and shielding part, can be removed from the main channel and scale inhibition channel to clean the filter screen or shielding part. The operation is simple and convenient. Attached Figure Description

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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).

[0048] In heating and cooling equipment such as gas boilers, water heaters, reverse osmosis systems, and water purifiers, scale easily forms in the pipes and equipment during use. This scale buildup can cause blockages, affecting the normal operation of the equipment. Furthermore, the water quality can impact the filtration efficiency of the reverse osmosis membrane in water purifiers or reverse osmosis systems. Therefore, descaling is necessary to improve water quality, reduce scale buildup, and thus improve equipment efficiency and extend its lifespan.

[0049] This application provides a scale inhibitor valve, see reference. Figures 1 to 3The scale-inhibiting valve includes a valve body 1, a scale-inhibiting part 2, a shielding part 3, and a plug 4. The valve body 1 has a main channel 10. The scale-inhibiting part 2 is located on one side of the valve body 1 and has a scale-inhibiting channel 20 for placing a scale-inhibiting plate 5. The scale-inhibiting channel 20 and the main channel 10 are arranged at an angle. Along the axial direction of the scale-inhibiting channel 20, the scale-inhibiting channel 20 has a first opening 21 and a second opening 22 arranged opposite to each other. The first opening 21 is connected to the main channel 10. The shielding part 3 is at least partially located in the scale-inhibiting channel 20 to separate the scale-inhibiting plate 5 from the main channel 10. The shielding part 3 has a plurality of through holes 30 to connect the main channel 10 and the scale-inhibiting channel 20. The plug 4 is detachably located in the scale-inhibiting part 2 to block the second opening 22.

[0050] The valve body 1 is connected to the scale-inhibiting part 2. The axis of the main channel 10 is angled to the axis of the scale-inhibiting channel 20. The first opening 21 of the scale-inhibiting channel 20 is connected to the main channel 10. The shielding part 3 is at least partially disposed within the scale-inhibiting channel 20 to separate the scale-inhibiting channel 20 from the main channel 10. The shielding part 3 holds the scale-inhibiting plate 5 within the scale-inhibiting channel 20. The shielding part 3 has multiple through holes 30 that can connect the main channel 10 and the scale-inhibiting channel 20, allowing water in the main channel 10 to enter the scale-inhibiting channel 20. The water comes into contact with the scale-inhibiting plate 5 within the scale-inhibiting channel 20. The scale-inhibiting plate 5 is slowly released upon contact with water and can combine with metal ions in the water, thereby changing the water quality and reducing scale formation. The shielding plate can be completely located within the scale-inhibiting channel 20, or it can be partially located within the scale-inhibiting channel 20 and partially located within the main channel 10, as long as the shielding part 3 can prevent the scale-inhibiting plate 5 from entering the main channel 10 between the main channel 10 and the scale-inhibiting channel 20.

[0051] The plug 4 is detachably disposed at the second opening 22 of the scale inhibitor 2, thereby enabling the addition of the scale inhibitor 5. The connection between the plug 4 and the scale inhibitor 2 can be a threaded connection, a snap-fit ​​connection, or other detachable connection methods.

[0052] The scale inhibitor valve proposed in this application embodiment has a plug 4 detachably disposed in the scale inhibitor part 2, and a shielding part 3 at least partially located in the scale inhibitor channel 20. The plug 4, the scale inhibitor part 2, and the shielding part 3 together form a receiving cavity for accommodating the scale inhibitor sheet 5. The shielding part 3 is provided with multiple through holes 30 so that water in the main channel 10 can flow into the scale inhibitor channel 20. The water entering the scale inhibitor channel 20 comes into full contact with the scale inhibitor sheet 5, so that the scale inhibitor sheet 5 dissolves well in the water, thereby removing scale components in the water, improving water quality, enhancing water safety, reducing scale deposition in the pipe, improving equipment efficiency, and extending equipment service life.

[0053] In addition, the scale inhibitor 2 is located on one side of the valve body 1. The axis of the scale inhibitor channel 20 is set at an angle to the axis of the main channel 10. The scale inhibitor channel 20 is set perpendicularly or inclined to the main channel 10. That is to say, the scale inhibitor channel 20 is set perpendicularly or inclined to one side of the main channel 10. In other words, the scale inhibitor 5 in the scale inhibitor channel 20 is located on one side of the main channel 10, which can reduce the impact of water in the main channel 10 on the scale inhibitor 5, thereby reducing the dissolution rate of the scale inhibitor 5. Furthermore, the scale inhibitor channel 20 and the scale inhibitor 5 are located on one side of the main channel 10, which can reduce the influence of the scale inhibitor 5 on the flow rate of the main channel 10.

[0054] The shielding part 3 can not only allow water in the main channel 10 to enter the scale inhibition channel 20, causing the scale inhibition plate 5 in the scale inhibition channel 20 to dissolve and react with ions in the water, but also prevent the scale inhibition plate 5 from leaving the scale inhibition channel 20 and entering the main channel 10.

[0055] Optionally, refer to Figure 1 and Figure 2 The angle between the axis of the main channel 10 and the axis of the scale inhibition channel 20 is α, satisfying: 0° < α < 90°. The angle between the axis of the main channel 10 and the axis of the scale inhibition channel 20 is between 0° and 90°, meaning that the scale inhibition channel 20 is inclined on the main channel 10. This allows the scale inhibition plate 5 dissolved in the scale inhibition channel 20 to better enter the main channel 10 through the through hole 30 of the shielding part 3, thereby enabling the scale inhibition plate 5 to fully react with the metal ions in the water.

[0056] Optionally, along the axial direction of the main channel 10, the main channel 10 has an inlet 101 and an outlet 102 arranged opposite to each other, and the scale inhibition channel 20 is inclined towards the inlet 101. After the water in the main channel 10 enters the scale inhibition channel 20, the scale inhibition sheet 5 slowly dissolves. The inclination of the scale inhibition channel 20 towards the inlet 101 makes it easier for the dissolved scale inhibition sheet 5 to flow into the main channel 10 under the combined action of gravity and water flow, thereby improving the effect of the scale inhibition sheet 5.

[0057] Optionally, refer to Figure 1 and Figure 2 The scale-inhibiting channel 20 includes a first segment 201 and a second segment 202 connected together. A first opening 21 is provided at the end of the first segment 201 away from the second segment 202, and a second opening 22 is provided at the end of the second segment 202 away from the first segment 201. The inner diameter of the first segment 201 is smaller than the inner diameter of the second segment 202 to form a first stepped surface 203. The shielding part 3 abuts against the first stepped surface 203.

[0058] The first segment 201 is connected to the main channel 10 through the first opening 21, and the second segment 202 is connected to the first segment 201 through the through hole 30 of the shielding part 3. The scale inhibitor 5 is disposed in the second segment 202. The connection between the first segment 201 and the second segment 202 forms a first stepped surface 203. The shielding part 3 abuts against the first stepped surface 203, thereby keeping the shielding part 3 within the scale inhibitor channel 20 and preventing it from entering the main channel 10 due to water flow. This allows the shielding part 3 to shield the scale inhibitor 5 within the scale inhibitor channel 20.

[0059] Optionally, refer to Figure 2 The second segment 202 has a third opening 23 communicating with the main channel 10. Since the scale-inhibiting channel 20 is inclined to the main channel 10, at least a portion of the cross-section of the first segment 201 is an incomplete circle along the axial direction of the scale-inhibiting channel 20. A first stepped surface 203 is formed near the first opening 21. The first stepped surface 203 is an incomplete annulus. A portion of the shielding part 3 abuts against the first stepped surface 203, and another portion of the shielding part 3 extends into the main channel 10. A gap exists between the portion of the shielding part 3 extending into the main channel 10 and the sidewall of the second segment 202; this gap is configured as the third opening 23.

[0060] The second section 202 of the scale inhibition channel 20 is connected to the main channel 10 through the third opening 23. Water enters the second section 202 from the main channel 10 through the third opening 23 and interacts with the scale inhibition plate 5 in the second section 202. The third opening 23 diverts the water in the main channel 10 and increases the amount of water entering the scale inhibition channel 20, so that the scale inhibition plate 5 can fully interact with the ions in the water.

[0061] It should be understood that when the second segment 202 is provided with a third opening 23 that communicates with the main channel 10, the shielding part 3 may not be provided with a through hole 30, or the shielding part 3 may be provided with a through hole 30.

[0062] For example, in one embodiment, the first opening 21 of the first segment 201 of the scale-inhibiting channel 20 is connected to the main channel 10, and the second segment 202 of the scale-inhibiting channel 20 is connected to the main channel 10 through the third opening 23. That is, the water entering the second segment 202 is divided into two paths. One path of water enters the second segment 202 from the main channel 10 through the third opening 23 and interacts with the scale-inhibiting sheet 5 in the second segment 202. The other path of water enters the first segment 201 through the first opening 21, and then enters the second segment 202 through the through hole 30 of the shielding part 3 and interacts with the scale-inhibiting sheet 5 in the second segment 202.

[0063] Optionally, refer to Figure 1The scale inhibitor valve also includes a first housing 6, which is connected to the shielding part 3. The first housing 6 is located in the second section 202. The first housing 6, the shielding part 3, and the plug 4 together form a receiving cavity for accommodating the scale inhibitor 5.

[0064] The first housing 6 is located within the second section 202. Water from the main channel 10 enters the second section 202 through the shielding part 3. The first housing 6 can fix the shielding part 3, reducing the movement of the shielding part 3 due to water flow. Furthermore, since the scale inhibitor 5 is located within the receiving cavity formed by the first housing 6, the shielding part 3, and the plug 4, the first housing 6 can also fix the scale inhibitor 5.

[0065] Optionally, refer to Figure 3 The axis of the main channel 10 is perpendicular to the axis of the scale-inhibiting channel 20. This perpendicularity allows water flow from the main channel 10 to more easily enter the scale-inhibiting channel 20, resulting in better dissolution of the scale-inhibiting plate 5 and thus enhancing its effectiveness. Furthermore, the perpendicularity of the scale-inhibiting channel 20 to the main channel 10 simplifies the manufacturing process.

[0066] Optionally, refer to Figure 3 The scale inhibition valve also includes a filter screen 7 disposed in the main channel 10. The filter screen 7 is connected to the shielding part 3. The filter screen 7 is constructed as a ring structure, and the axis of the filter screen 7 is perpendicular to the axis of the main channel 10.

[0067] The axis of the main channel 10 is set perpendicular to the axis of the scale-inhibiting channel 20, that is, the axis of the filter screen 7 is parallel to the axis of the scale-inhibiting channel 20. This means that the scale-inhibiting part 2 is set perpendicularly on one side of the valve body 1. The scale-inhibiting part 2 does not block the water flow in the main channel 10. The filter screen 7 is set in the main channel 10 to filter the water in the main channel 10 and remove impurities from the water. The filter screen 7 is connected to the shielding part 3. The filter screen 7 can be removed from the scale-inhibiting channel 20 to achieve the purpose of replacing or cleaning the filter screen 7.

[0068] Optionally, refer to Figure 3 The inner wall of the main channel 10 is provided with a protrusion 11. Along the axial direction of the scale-inhibiting channel 20, the protrusion 11 is arranged opposite to the shielding part 3. The end of the filter screen 7 away from the shielding part 3 overlaps and cooperates with the protrusion 11.

[0069] A protrusion 11 is provided inside the main channel 10. The end of the filter screen 7 away from the shielding part 3 is fitted onto the protrusion 11 to fix the filter screen 7 and reduce the chance of the filter screen 7 shifting due to water flow impact.

[0070] Optionally, refer to Figure 3 Along the axial direction of the main channel 10, a fourth opening 70 is provided on one side of the filter screen 7. The filter screen 7 is provided with a fourth opening 70 on one side along the axial direction of the main channel 10 to reduce the restriction of the filter screen 7 on the water flow rate in the main channel 10.

[0071] Optionally, refer to Figure 3 Along the axial direction of the main channel 10, the main channel 10 has an inlet 101 and an outlet 102 that are arranged opposite to each other, and a fourth opening 70 faces the inlet 101.

[0072] The fourth opening 70 faces the inlet 101, which can filter the water in the main channel 10 while also reducing the restriction of the filter screen 7 on the water flow rate in the main channel 10.

[0073] Optionally, refer to Figure 3 The scale inhibitor valve also includes a second housing 8, which is located in the scale inhibitor channel 20. The second housing 8 is connected to the shielding part 3. The plug 4, the second housing 8 and the shielding part 3 together form a receiving cavity for accommodating the scale inhibitor 5. The second housing 8, the shielding part 3 and the filter screen 7 are constructed as an integral molded part.

[0074] The filter screen 7, the shielding part 3, and the second housing 8 are integrally formed. When the filter screen 7 or the shielding part 3 needs to be cleaned or replaced, simply remove the plug 4 and pull out the second housing 8. The second housing 8, along with the shielding part 3 and the filter screen 7, will separate from the main channel 10 and the scale-inhibiting channel 20, allowing the filter screen 7 or the shielding part 3 to be cleaned. The operation is simple and convenient.

[0075] In one specific embodiment, reference Figure 2 The scale inhibitor valve also includes a first sealing element 91. The plug 4 includes a connecting part and an end. The connecting part is threadedly connected to the inner circumferential surface of the scale inhibitor channel 20. The outer circumferential surface of the connecting part is provided with a first groove. The first groove is located on the side of the connecting part near the end. The first sealing element 91 is located in the first groove and abuts against the inner circumferential surface of the scale inhibitor channel 20.

[0076] In another specific embodiment, reference Figure 1 and Figure 3 The scale inhibitor valve also includes a second seal 92. The plug 4 includes a connected peripheral wall and a bottom wall. The peripheral wall is threadedly connected to the outer peripheral surface of the scale inhibitor channel 20. The second seal 92 is located between the end face of the second opening 22 and the bottom wall.

[0077] In this application, the inlet 101 and outlet 102 can be on either side of the main channel 10. When water flows into the main channel 10, some water enters the scale inhibition channel 20 and comes into contact with the scale inhibition plate 5. When the scale inhibition plate 5 comes into contact with water, it releases ions that combine with metal ions in the water, thereby changing the water quality, reducing scale buildup, protecting water quality safety, and extending the service life of the equipment.

[0078] It should also be noted that 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 a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
