Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a bypass valve and a water softener. Background Art

[0002] There are two common water softening technologies: one is to remove calcium and magnesium ions in water through ion exchange resin, thereby reducing the water quality hardness; the other is to use the high energy generated by nanocrystals to package free calcium, magnesium, and bicarbonate ions in water into nanoscale crystals, thereby preventing the formation of scale by free ions. Compared with tap water, the softened water with reduced hardness has a very obvious taste and feel.

[0003] Existing water softeners are generally installed on the main pipeline of household water, resulting in all water use points in the whole house using softened water. However, there are situations where the water use points do not need to use softened water, such as the kitchen. Since the water quality softening process of the water softener will generate waste water and consume materials such as ion exchange resin, using softened water at water use points that do not need it will not only cause waste of resources such as ion exchange resin and water, but also increase the burden on the water softener and reduce the service life of the water softener.

They are only for convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0047] The present utility model provides a bypass valve, which can be used in a water softener. Specifically, as Figures 1 to 16 shown, the bypass valve includes a valve body 100, a first valve core 200, and a second valve core 300. The valve body 100 includes a raw water part and a softened water part. A raw water channel 110 is formed in the raw water part, and a softened water channel 120 is formed in the softened water part. The raw water channel 110 forms a raw water inlet 101, a first raw water outlet 102, and a second raw water outlet 103 on the valve body 100. The first raw water outlet 102 is used for directly discharging raw water, and the second raw water outlet 103 is used for communicating with the water inlet of the water softening mechanism (not shown in the figure) of the water softener. The softened water channel 120 includes a softened water inlet 104 and at least one softened water outlet. The softened water inlet 104 is used for communicating with the water outlet of the water softening mechanism. The first valve core 200 is rotatably arranged in the raw water channel 110, and the second valve core 300 is rotatably arranged in the softened water channel 120. The first valve core 200 has a first position for conducting the raw water inlet 101, the first raw water outlet 102, and the second raw water outlet 103, and the second valve core 300 has a second position for conducting the softened water inlet 104 and the softened water outlet.

[0048] As Figures 2 to 4 shown, the bypass valve has a first state in which the first valve core 200 is in the first position and the second valve core 300 is in the second position. When the first valve core 200 of the bypass valve provided by the present utility model is in the first position and the second valve core 300 is in the second position, as Figure 3 shown, the raw water entering the raw water channel 110 from the raw water inlet 101 is split. Part of the raw water directly flows to the raw water outlet point through the first raw water outlet 102, so that the raw water outlet point can directly supply raw water. Another part of the raw water flows to the water softening mechanism through the second raw water outlet 103. The water softening mechanism softens the quality of the raw water. After being softened by the water softener, this part of the raw water becomes softened water. The softened water flows into the bypass valve again through the softened water inlet 104 and flows to the softened water outlet through the softened water channel 120 (for example Figure 1The first soft water outlet 105 and the second soft water outlet 106) finally flow to the soft water outlet point, enabling the soft water outlet point to supply soft water. Compared with the bypass valve in the prior art, this bypass valve realizes the separation of the quality of raw water and soft water, enabling different water use points to use raw water and soft water according to needs, which is beneficial to reducing resource waste in the process of softening raw water into soft water and is also beneficial to reducing the burden on the soft water mechanism during the process of softening raw water.

[0049] It should be noted that the number of the first raw water outlets 102 can be set to multiple according to needs, so as to supply raw water to multiple raw water use points. The number of soft water outlets can be set to one according to needs. When there is only one soft water outlet, this soft water outlet is connected to the main household water pipeline. When there are two or more soft water outlets, one of the soft water outlets (such as Figure 1 the first soft water outlet 105 in Figure 1 is used to connect to the main household water pipeline, and the remaining soft water outlets (such as

[0050] Continue to refer to Figure 3 As shown, in some embodiments, a bypass section is provided between the raw water section and the soft water section. A bypass channel 130 is provided in the bypass section. One end of the bypass channel 130 communicates with the raw water channel 110, and the other end of the bypass channel 130 communicates with the soft water channel 120; the first valve core 200 in the first position blocks one side port of the bypass channel 130; the second valve core 300 in the second position blocks the other side port of the bypass channel 130.

[0051] That is to say, when the soft water mechanism can work normally to soften the quality of the raw water, the two ports of the bypass channel 130 are blocked by the first valve core 200 in the first position and the second valve core 300 in the second position, and the raw water entering the raw water channel 110 from the raw water inlet 101 cannot directly enter the soft water channel 120 through the bypass channel 130.

[0052] When the soft water mechanism fails and cannot work normally, and the user still has a water use demand at the raw water use point where raw water was originally used, in order to avoid delaying the user's water use, in some embodiments, such as Figure 5 and me Figure 6As shown, the first valve core 200 has a third position for blocking the second raw water outlet 103, and the bypass valve has a second state in which the first valve core 200 is in the third position and the second valve core 300 is in the second position. In this way, the main pipeline of the water softener can be disconnected, facilitating the maintenance and replacement of the water softening mechanism.

[0053] When the bypass valve is in the second state, as Figure 6 shown, the raw water entering the raw water channel 110 from the raw water inlet 101 directly flows through the first raw water outlet 102 to the raw water outlet point, enabling the raw water outlet point to directly supply raw water. It should be noted that when there is only one first raw water outlet 102, the raw water entering the raw water channel 110 from the raw water inlet 101 does not split and all flows directly through the first raw water outlet 102 to the raw water outlet point; when there are multiple first raw water outlets 102, the raw water entering the raw water channel 110 from the raw water inlet 101 can split and flow directly through multiple first raw water outlets 102 to multiple raw water outlet points.

[0054] When the water softening mechanism fails to work properly and the user still has a water usage requirement at both the raw water usage point that originally used raw water and the soft water usage point that originally used soft water, in order to avoid delaying the user's water usage, as Figure 7 and Figure 8 shown, the first valve core 200 has a third position for blocking the second raw water outlet 103, the second valve core 300 has a fourth position for blocking the soft water inlet 104, and the bypass valve has a third state in which the first valve core 200 is in the third position and the second valve core 300 is in the fourth position to conduct the bypass channel 130.

[0055] When the bypass valve is in the third state, as Figure 8 shown, the raw water entering the raw water channel 110 from the raw water inlet 101 splits, with a part of the raw water directly flowing through the first raw water outlet 102 to the outlet point, enabling the outlet point to directly supply raw water, and the other part of the raw water directly flowing through the bypass channel 130 to the soft water channel 120 and flowing through the first soft water outlet 105 and the second soft water outlet 106 to the outlet point, enabling the water usage point that originally supplied soft water to temporarily supply raw water for emergency. In this way, normal water usage in the user's home can be ensured when the water softening mechanism fails.

[0056] In some embodiments, the first valve core 200 further has a fifth position (not shown in the figure) for blocking the first raw water outlet 102. Such a setting enables soft water to be output from the main household water pipeline and other devices that require soft water when the user does not need water quality separation. It should be noted that at this time, the bypass channel 130 is in a blocked state, and the blocking of the bypass channel 130 and the blocking of the first raw water outlet 102 can be achieved by adjusting the structure of the first valve core 200 or by adding other switching structures.

[0057] Further, in some embodiments, the second valve core 300 further has a sixth position (not shown in the figure) for blocking the second soft water outlet 106 of other devices that require soft water externally. Such a setting enables only the first soft water outlet 105 connected to the main household water pipeline to be opened. When the first valve core 200 further has a fifth position for blocking the first raw water outlet 102 and the second valve core 300 is in the sixth position, all the raw water entering the bypass valve from the raw water inlet 101 is softened by the soft water mechanism and then all flows into the main household water pipeline through the first soft water outlet 105. In this way, when the user does not need water quality separation, the bypass valve can still be used, improving the versatility of the bypass valve and expanding the applicable range of the bypass valve.

[0058] To simplify the structure of the channels inside the bypass valve and the structure of the first valve core 200, in some embodiments, the raw water channel 110 and the bypass channel 130 are connected in a "cross" shape, and the first valve core 200 is arranged at the intersection of the raw water channel 110 and the bypass channel 130. In this way, by rotating the first valve core 200, the valve core can be switched between the first position and the third position.

[0059] In some embodiments, a first installation cavity is formed at the intersection of the raw water channel 110 and the bypass channel 130. The first valve core 200 is rotatably connected in the first installation cavity. The valve cavity of the first valve core 200 has at least three first valve ports 202, and the included angle between the axes of two adjacent first valve ports 202 is 90°.

[0060] When the raw water channel 110 has only one first raw water outlet 102, in one embodiment, the valve cavity of the first valve core 200 has three first valve ports 202; in another embodiment, as Figure 9 and Figure 10 shown, the valve cavity of the first valve core 200 has four first valve ports 202, and a first sealing gasket 201 is arranged in one of the first valve ports 202. When the first sealing gasket 201 rotates to face the channel opening of the bypass channel 130, the sealing of this channel opening can be achieved. At this time, the first valve core 200 is in the first position, and when the first sealing gasket 201 rotates to face the second raw water outlet 103, the sealing of the second raw water outlet 103 can be achieved. At this time, the first valve core 200 is in the third position.

[0061] When the raw water channel 110 has multiple first raw water outlets 102, the valve cavity of the first valve core 200 can be provided with four or more than four first valve ports 202, and the included angle between adjacent first valve ports 202 can be flexibly adjusted according to requirements, not limited to 90°.

[0062] In order to simplify the structure of the inner channels of the bypass valve and the structure of the second valve core 300, in some embodiments, the soft water channel 120 and the bypass channel 130 are connected in a "cross" shape, and the second valve core 300 is arranged at the intersection of the soft water channel 120 and the bypass channel 130. Thus, by rotating the second valve core 300, the valve core can be switched between the second position and the third position.

[0063] In some embodiments, a second installation cavity is formed at the intersection of the soft water channel 120 and the bypass channel 130. The second valve core 300 is rotatably connected in the second installation cavity. The valve cavity of the second valve core 300 has at least three second valve ports 302, and the included angle between the axes of two adjacent second valve ports 302 is 90°.

[0064] When the soft water channel 120 only has the first soft water outlet 105 and the second soft water outlet 106, in one embodiment, the valve cavity of the second valve core 300 has three second valve ports 302; in another embodiment, as Figure 13 and Figure 14 shown, the valve cavity of the second valve core 300 has four second valve ports 302. A second sealing gasket 301 is arranged in one of the second valve ports 302. When the second sealing gasket 301 rotates to face the other channel opening of the bypass channel 130, the sealing of this channel opening can be realized. At this time, the second valve core 300 is in the second position. When the second sealing gasket 301 rotates to face the soft water inlet 104, the sealing of the soft water inlet 104 can be realized. At this time, the second valve core 300 is in the fourth position.

[0065] When the soft water channel 120 has one or more than two soft water outlets, the valve cavity of the second valve core 300 can be provided with other numbers of second valve ports 302, and the included angle between adjacent second valve ports 302 can be flexibly adjusted according to requirements, not limited to 90°.

[0066] In order to facilitate the user to rotate the first valve core 200, in some embodiments, as Figure 9 and Figure 10 shown, the bypass valve further includes a first rotating handle 400, and the first rotating handle 400 is arranged on the first valve core 200.

[0067] In some embodiments, as Figure 11 and Figure 12As shown in the figure, a first clamping portion 210 is provided on the end cover of the first valve core 200, and a second clamping portion 410 that cooperates with the first clamping portion 210 is provided on the first rotating handle 400.

Optionally, one of the first clamping portion 210 and the second clamping portion 410 can be a special-shaped slot, and the other can be a matching special-shaped clamping block, or both can be a combination of a slot and a clamping block.

Optionally, one of the third clamping portion 310 and the fourth clamping portion 510 can be a special-shaped slot, and the other can be a matching special-shaped clamping block, or both can be a combination of a slot and a clamping block.
