Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water treatment, in particular to a moving valve plate, a valve core assembly, a multi-way valve and a water softener. BACKGROUND

[0002] At present, the tap water used in cities is usually collected from underground water, but the underground water usually contains a large amount of calcium ions and magnesium ions, which causes the water to scale during use, thereby causing damage to electrical appliances. Softening the hard water and reducing the hardness of drinking water can effectively prevent stone disease, reduce the burden on the heart and kidneys, and benefit people's health. Therefore, the water softener capable of softening hard water is used more and more frequently in life.

[0003] The water softener usually exchanges the calcium and magnesium ions in the water with the functional ions on the resin, thereby adsorbing the excess calcium and magnesium ions in the water to achieve the purpose of removing scale. The water softener in the prior art usually comprises an integrated water path and a soft water device and a salt supply device connected to the integrated water path. Raw water enters the soft water device through the integrated water path, and the resin layer in the soft water device can soften the raw water and output soft water through the integrated water path for use by the user. When all the resin is saturated with calcium and magnesium ions, the water softener cannot soften the tap water any more, at which time the exchange resin needs to be backwashed and regenerated. The salt in the salt supply device is dissolved and saturated, and then enters the soft water device, and the saturated salt solution soaks the resin, so that a large number of sodium ions in the saturated salt solution replace the calcium and magnesium ions adsorbed on the resin. When the calcium and magnesium ions are replaced, the resin achieves the effect of reduction and regeneration, and is ready for the next water softening work.

[0004] In the existing water softener, the multi-way valve is a core component for controlling the flow direction of water in the integrated water path. By switching the multi-way valve in different stations, the water flow can be controlled in different directions in different structures, thereby realizing the functions of water supply, backwashing, regeneration, water replenishment and the like. However, the soft water can only be supplied in the water supply state, and the user cannot use the water through the water softener in other functional states. SUMMARY

[0053] Reference Figure 1 , Figure 1The internal structure of the multi-way valve 100 in an embodiment of the present application is shown. An embodiment of the present application provides a water softener (not shown in the figure), which removes calcium and magnesium ions in raw water through ion exchange resin, thereby reducing water hardness to provide soft water with low calcium and magnesium ion content for users. As described in the background, the water softener includes an integrated water path, a water softening device and a salt supply device connected to the integrated water path, and a multi-way valve 100 provided in the integrated water path for controlling the flow direction of water. The multi-way valve 100 generally has five stations, namely water supply, backwashing, regeneration, water replenishment, and forward washing.

[0054] When the multi-way valve 100 is in the water supply station, the water softener can soften the raw water to provide qualified soft water for users. When the multi-way valve 100 is in the backwashing station, the raw water flows from bottom to top through the resin layer in the water softening device to achieve the purpose of strong washing. When the multi-way valve 100 is in the regeneration station, the brine in the salt supply device flows from bottom to top through the resin layer in the water softening device to achieve the purpose of cleaning and ion exchange. When the multi-way valve 100 is in the water replenishment station, the raw water enters the salt supply device to replenish water for the salt supply device. When the multi-way valve 100 is in the forward washing station, the raw water flows from top to bottom through the resin layer in the water softening device, the puffed resin layer slowly settles under the action of water pressure, and exchanges ions while precipitating pollutants.

[0055] The multi-way valve 100 with only five stations can only provide one high concentration of regeneration salt concentration, so the regeneration rate of the resin is low, resulting in a small water production of the water softener. Moreover, the water softener lacks a slow washing function, and the water softening process is relatively rough. In order to improve the regeneration rate of the resin and optimize the water softening process, the multi-way valve 100 of the present application adds one regeneration station and one slow washing station based on the five stations of water supply, backwashing, regeneration, water replenishment, and forward washing. The two regeneration stations can provide two different regeneration salt concentrations, thereby improving the regeneration rate of the resin. The slow washing station can make the raw water slowly wash the resin layer from bottom to top, carrying away broken resin and residual pollutants, thereby improving the utilization rate of brine.

[0056] During the research, the inventors found that, on the one hand, when the multi-way valve 100 is in the water supply station, the water softening process of the water softener generally takes a long time, and if a user has a water demand during the water softening process of the water softener, the water softener cannot meet the demand. On the other hand, when the multi-way valve 100 is in a non-water supply station (such as backwashing, regeneration, slow washing, water replenishment, and forward washing), the raw water enters the water softening device or the salt supply device, and at this time, if a user needs water, the water softener also cannot meet the demand. Therefore, in order to provide a water softener that can continuously supply water, the present application provides a multi-way valve 100 that can continuously flow water, which can provide soft water after water softening and provide raw water when soft water cannot be supplied.

[0057] In some embodiments, the multi-way valve 100 comprises a valve body 20, a valve core assembly 60 and a valve stem 40. Specifically, the valve body 20 is in a hollow housing structure, and the valve body 20 is provided with a valve cavity 21 which is open at one end. The valve core assembly 60 is accommodated in the valve cavity 21 of the valve body 20, and the first axial end of the valve stem 40 extends into the valve cavity 21 and is drivingly connected with the valve core assembly 60, and the second axial end of the valve stem 40 extends out of the valve cavity 21 and is connected with a driving unit. In this way, under the driving of the driving unit, the valve stem 40 can drive the valve core assembly 60 to switch between different states, so as to change the working position of the multi-way valve 100 to realize different functions.

[0058] In combination Figures 2 to 6 As shown, the valve core assembly 60 comprises a fixed valve plate 61 and a movable valve plate 63, the fixed valve plate 61 is fixedly installed in the valve cavity 21 and located at the bottom of the valve cavity 21. The movable valve plate 63 is arranged above the fixed valve plate, and the first axial end of the valve stem 40 is drivingly connected with the movable valve plate 63 and drives the movable valve plate 63 to rotate relative to the fixed valve plate 61 under the driving of the driving unit.

[0059] The movable valve plate 63 has a first position and a second position relative to the fixed valve plate 61. When the fixed valve plate 61 is in the first position, the multi-way valve 100 is in a non-water supply position, i.e. a backwashing, regeneration, slow washing, water supplementing or forward washing position. When the fixed valve plate 61 is in the second position, the multi-way valve 100 is in a water supply position. It can be understood that the first position is not a fixed position, but a range position, and within this range position, the multi-way valve 100 cannot supply soft water.

[0060] Wherein, the fixed valve plate 61 has a first communication hole 612 which is open through the thickness direction of the fixed valve plate 61, the movable valve plate 63 comprises a main body part 631 and a first blocking part 632 which is protrudingly arranged on the outer periphery of the main body part 631, the main body part 631 has a first end face 6311 and a second end face (not shown in the figure) which are oppositely arranged in the thickness direction (i.e. the direction perpendicular to the bottom of the valve cavity 21), and the fixed valve plate 61 is attached to one side of the first end face 6311 of the main body part. Moreover, the outer periphery edge of the main body part 631 is further configured to form a raw water flow channel YS, and the raw water flow channel YS is jointly enclosed with the outer periphery edge of the first blocking part 632 to form a closed circumference.

[0061] Thus, in the process of the rotation of the movable valve disc 63 relative to the fixed valve disc 61, the raw water flow passage YS can be communicated with the first communication hole 612, so as to realize the raw water supply. Alternatively, in the process of the rotation of the movable valve disc 63 relative to the fixed valve disc 61, the raw water flow passage YS and the first communication hole 612 are blocked by the first blocking part 632, at this time, the first communication hole 612 is used for supplying the softened water, the first blocking part 632 blocks the raw water flow passage YS and the first communication hole 612, so as to avoid the raw water flowing into the first communication hole 612 and mixing with the softened water. Thus, when the multi-way valve 100 is in the water supply position, the user can use the softened water. When the multi-way valve 100 is in the non-water supply position, the user can use the raw water, and the raw water and the softened water share the same water outlet, i.e., the first communication hole 612, without the need for long waiting or additional water faucet, which is fast and convenient.

[0062] Specifically, the fixed valve disc 61 is in a disc structure, the main body part 631 is in a disc structure similar to the fixed valve disc 61, and the first blocking part 632 is arranged along the circumference of the main body part 631. When the movable valve disc 63 is in the first position, the main body part 631 covers part of the first communication hole 612, and the projection of the first blocking part 632 on the fixed valve disc 61 is staggered with the first communication hole 612. At this time, the remaining part of the first communication hole 612 not covered by the main body part 631 is communicated with the raw water flow passage YS, and the raw water entering the multi-way valve 100 can directly flow to the first communication hole 612. When the movable valve disc 63 is in the second position, the main body part 631 covers part of the first communication hole 612, and the first blocking part 632 covers the remaining part of the first communication hole 612, so as to completely cover the first communication hole 612, at this time, the raw water flow passage YS is separated from the first communication hole 612 by the first blocking part 632, and the raw water cannot enter the first communication hole 612.

[0063] In one embodiment, the main body part 631 further has a flow guide groove 6312, and in the radial direction of the movable valve disc 63, the first blocking part 632 is located on one side of the flow guide groove 6312, and at least part of the flow guide groove 6312 is located in the fan-shaped area enclosed by the first blocking part 632 and the center of the main body part 631. The fixed valve disc 61 is provided with a second communication hole 614, when the movable valve disc 63 is rotated relative to the fixed valve disc 61 to the second position, the raw water flow passage YS is blocked from the first communication hole 612, at this time, the second communication hole 614 is communicated with the first communication hole 612 through the flow guide groove 6312, at this time, the softened water flows from the second communication hole 614 to the first communication hole 612, so as to realize the softened water supply.

[0064] In one of the embodiments, the fixed valve plate 61 further has a plurality of third communication holes 616 formed therethrough. When the movable valve plate 63 is rotated relative to the fixed valve plate 61 to the first position, the raw water flow passage YS is communicated with the first communication hole 612, and at this time, the second communication hole 614 is selectively communicated with any one of the third communication holes 616 through the flow guide groove 6312, so that the multi-way valve 100 having the valve core assembly 60 can be switched among different positions in the non-water supply position.

[0065] Specifically, the first communication hole 612, the second communication hole 614 and the plurality of third communication holes 616 are arranged at intervals in the circumferential direction of the fixed valve plate 61, and the plurality of third communication holes 616 are located on the same side of the second communication hole 614. Specifically, in one of the embodiments, the second communication hole 614 is arranged in the form of a ring extending in the circumferential direction of the fixed valve plate 61.

[0066] In the specific embodiment, the fixed valve plate 61 has three third communication holes 616, which are located on the same side of the second communication hole 614, and each of the third communication holes 616 is circular or elliptical. It can be understood that the number and shape of the third communication holes 616 are not limited and can be set as required to meet different requirements.

[0067] In one of the embodiments, the flow guide groove 6312 includes a first flow guide portion 63121, a second flow guide portion 63123 and a third flow guide portion 63125 communicated in sequence. The first flow guide portion 63121 and the third flow guide portion 63125 are arranged at intervals in the circumferential direction of the movable valve plate 63, and the second flow guide portion 63123 extends longitudinally in the circumferential direction of the movable valve plate 63. The opposite ends of the second flow guide portion 63123 in the circumferential direction of the movable valve plate 63 are connected to the first flow guide portion 63121 and the third flow guide portion 63125, respectively, and the second blocking portion 633 is formed between the first flow guide portion 63121 and the third flow guide portion 63125 in the radial direction of the movable valve plate 63, and is located on the side of the second flow guide portion 63123 close to the first blocking portion 632.

[0068] When the movable valve plate 63 and the fixed valve plate 61 are attached to each other and are in the second position, the orthogonal projection of the first blocking portion 632 on the fixed valve plate 61 coincides with the first communication hole 612 to block the raw water flow passage YS and the first communication hole 612. At this time, the orthogonal projection of the first flow guide portion 63121 on the fixed valve plate 61 coincides with the first communication hole 612 to communicate the first communication hole 612, and the orthogonal projection of the third flow guide portion 63125 on the fixed valve plate 61 coincides with the second communication hole 614 to communicate the second communication hole 614. The first flow guide portion 63121 and the third flow guide portion 63125 are communicated through the second flow guide portion 63123, so that the first communication hole 612 and the second communication hole 614 are communicated.

[0069] When the moving valve plate 63 and the fixed valve plate 61 are attached to each other and in the first position, the projection of the first blocking part 632 on the fixed valve plate 61 is misaligned with the first communication hole 612 to communicate the raw water flow channel YS with the first communication hole 612, at this time the orthographic projection of the first flow guide part 63121 on the fixed valve plate 61 is coincided with the second communication hole 614 to communicate the second communication hole 614, the orthographic projection of the third flow guide part 63125 on the fixed valve plate 61 can be alternatively coincided with one of the third communication holes 616 to communicate the third communication hole 616. The orthographic projection of the second blocking part 633 on the fixed valve plate 61 can be coincided with one of the third communication holes 616 to cover the rest of the third communication holes 616 between the second communication hole and the third communication hole communicated by the flow guide groove 6312.

[0070] Thus, the flow guide groove 6312 on the moving valve plate 63 forms a "door" type structure, and the first blocking part 632 is arranged at the top of the "door" type structure. When the first blocking part 632 does not implement the blocking effect, the raw water flows to the first communication hole 612 through the raw water flow channel YS, and the water in one of the third communication holes 616 of the fixed valve plate 61 can flow into the second communication hole 614 in turn through the third flow guide part 63125, the second flow guide part 63123 and the first flow guide part 63121, and the rest of the third communication holes 616 between the above-mentioned mutually communicated third communication holes 616 and the second communication hole 614 are closed by the second blocking part 633. When the first blocking part 632 implements the blocking effect, the raw water flow channel YS is blocked with the first communication hole 612, at this time the liquid in the second communication hole 614 of the fixed valve plate 61 flows into the first communication hole 612 in turn through the third flow guide part 63125, the second flow guide part 63123 and the first flow guide part 63121.

[0071] Therefore, the water softener with the moving valve plate 63 can obtain raw water through the first communication hole 612 in the non-water supply state, and obtain soft water through the first communication hole 612 in the water supply state, thereby realizing continuous water supply in the multifunctional state of the water softener, so that the user can realize water use in any state of the water softener.

[0072] In an embodiment, the second flow guide part 63123 is located on the side of the second blocking part 633 away from the first blocking part 632, so that the projection of the second flow guide part 63123 on the fixed valve plate 61 is misaligned with the third communication hole 616 while the first flow guide part 63121 and the third flow guide part 63125 are communicated, the second flow guide part 63123 only plays a role of communicating the first flow guide part 63121 and the second flow guide part 63123, and does not cause the unnecessary communication of the third communication hole 616 to be in the conducting state.

[0073] As a preferred embodiment, in order to match the arrangement of the second communication hole 614 and the third communication hole 616, the outer contour of the flow guide groove 6312 is located in a virtual sector, which extends along the circumference of the movable valve plate 63. It can be understood that the shape and size of the flow guide groove 6312 are not limited to this, and can be set as required to meet different requirements.

[0075] The following describes the relationship between the first blocking part 632 and the flow guide groove 6312 and the first communication hole 612, the second communication hole 614, and the third communication hole 616 in the water supply position, the first regeneration position, the slow washing position, and the second regeneration position of the multi-way valve 100. It can be understood that the valve core assembly 60 of the application can also be used to realize the communication of other positions, and is not limited to the above functions. It should be noted that in the following embodiments, the slow washing channel 618 is formed on the side surface of the fixed valve plate 61 away from the movable valve plate 63, one end of the slow washing channel 618 communicates with one of the third communication holes 616, and the third communication hole 616 communicating with the slow washing channel 618 is located between the other two third communication holes 616. The slow washing channel 618 is used to communicate with the raw water inlet end, and the raw water flowing into the raw water inlet end can flow into the third communication hole 616 through the slow washing channel 618.

[0076] The second communication hole 614 is used for communication with the soft water device. Of the three third communication holes 616, the third communication hole 616 closest to the second communication hole 614 communicates with one of the salt supply channels of the salt supply device, the third communication hole 616 farthest from the second communication hole 614 communicates with another salt supply channel of the salt supply device, and the third communication hole 616 between the two third communication holes 616 communicates with the raw water inlet end through the slow washing channel 618 provided in the fixed valve plate 61.

[0077] When the multi-way valve 100 is in the water supply position, the valve rod 40 drives the movable valve plate 63 to rotate to the second position, at which time the main body part 631 covers part of the first communication hole 612, and the first blocking part 632 covers the remaining part of the first communication hole 612, thereby completely covering the first communication hole 612. The first flow guide part 63121 of the flow guide groove 6312 communicates with the first communication hole 612, and the third flow guide part 63125 communicates with the second communication hole 614. The raw water from the raw water inlet end flows into the resin layer in the soft water device through the second communication hole 614 to achieve ion exchange to form soft water, and then flows out from the first communication hole 612.

[0078] When the multi-way valve 100 is in the first regeneration position, the valve rod 40 drives the movable valve plate 63 to rotate to the first preset angle of the first position, at which time the main body part 631 covers part of the first communication hole 612, and the projection of the first blocking part 632 on the fixed valve plate 61 is offset from the first communication hole 612. The raw water from the raw water inlet end directly enters the first communication hole 612 to provide raw water through the raw water flow channel YS. At this time, the first flow guide part 63121 of the flow guide groove 6312 communicates with the end of the second communication hole 614 farthest from the third communication hole 616, and the third flow guide part 63125 communicates with the third communication hole 616 closest to the second communication hole 614. The salt water with the first concentration flowing out of one of the salt supply channels of the salt supply device flows into the third communication hole 616 closest to the second communication hole 614, and then flows into the second communication hole 614 through the third flow guide part 63125, the second flow guide part 63123 and the first flow guide part 63121 of the flow guide groove 6312 in turn, and finally flows into the resin layer in the soft water device to achieve the purpose of cleaning and ion exchange.

[0079] When the multi-way valve 100 is located at the slow washing station, the valve rod 40 drives the movable valve plate 63 to rotate to the second preset angle of the first position, at this time the main body part 631 covers part of the first communication hole 612, the projection of the first blocking part 632 on the fixed valve plate 61 is staggered with the first communication hole 612, and the raw water at the raw water inlet end directly enters the first communication hole 612 through the raw water flow channel YS to provide raw water. And, at this time, the first flow guide part 63121 of the flow guide groove 6312 is in communication with the middle part of the second communication hole 614, the third flow guide part 63125 is in communication with the third communication hole 616 between the two third communication holes 616, and the second blocking part 633 between the first flow guide part 63121 and the second flow guide part 63123 covers the third communication hole 616 closest to the second communication hole 614 to close it. The raw water at the raw water inlet end can also flow into the third communication hole 616 between the two third communication holes 616 through the slow washing channel 618 opened on the fixed valve plate 61, and then flow into the second communication hole 614 through the third flow guide part 63125, the second flow guide part 63123 and the first flow guide part 63121 of the flow guide groove 6312 in turn, and finally flow into the resin layer in the water softening device to remove broken resin and residual dirt.

[0080] When the multi-way valve 100 is located at the second regeneration station, the valve rod 40 drives the movable valve plate 63 to rotate to the third preset angle of the first position, at this time the main body part 631 covers part of the first communication hole 612, the projection of the first blocking part 632 on the fixed valve plate 61 is staggered with the first communication hole 612, and the raw water at the raw water inlet end directly enters the first communication hole 612 through the raw water flow channel YS to provide raw water. And, at this time, the first flow guide part 63121 of the flow guide groove 6312 is in communication with the end of the second communication hole 614 close to the third communication hole 616, the third flow guide part 63125 is in communication with the third communication hole 616 farthest from the second communication hole 614, and the second blocking part 633 between the first flow guide part 63121 and the second flow guide part 63123 covers the two third communication holes 616 closer to the second communication hole 614 to close them. The salt water with the second concentration flowing out of the second salt supply channel of the salt supply device flows into the third communication hole 616 farthest from the second communication hole 614, and then flows into the second communication hole 614 through the third flow guide part 63125, the second flow guide part 63123 and the first flow guide part 63121 of the flow guide groove 6312 in turn, and finally flows into the resin layer in the water softening device, achieving the purpose of cleaning and ion exchange.

[0081] In summary, under the drive of the valve stem 40, the moving valve plate 63 rotates relative to the fixed valve plate 61 to make the first blocking part 632 communicate or block the raw water flow channel YS and the first communication hole 612. When the first blocking part 632 blocks the raw water flow channel YS and the first communication hole 612, at this time, the first communication hole 612 and the second communication hole 614 are communicated through the flow guide groove 6312, the raw water is processed into soft water, and the soft water is supplied to the user. When the first blocking part 632 communicates the raw water flow channel YS and the first communication hole 612, the raw water directly flows to the first communication hole 612 through the raw water flow channel YS, and the raw water is supplied to the user.
