Referring to fig. 1, fig. 1 shows an internal structure schematic diagram of a multi-way valve in an embodiment of the present application. An embodiment of the present application provides a water softener (not shown) that includes a water softener that removes calcium and magnesium ions from raw water through an ion exchange resin, thereby reducing water hardness to provide soft water with a low content of calcium and magnesium ions to a user. As described in the background art, the water softener includes an integrated water path, and a water softening device and a salt supply device connected to the integrated water path, wherein a multi-way valve 100 for controlling the flow direction of water is disposed in the integrated water path, and the multi-way valve 100 generally has five stations of water supply, backwashing, regeneration, water replenishment and forward washing.

When the multi-way valve 100 is in the water supply station, the water softener can soften raw water to provide qualified softened water for users to use. When the multi-way valve 100 is at the backwashing station, raw water washes the resin layer from bottom to top in the water softening device to enable the resin layer to be fluffy so as to achieve the purpose of powerful washing. When the multi-way valve 100 is in the regeneration position, the brine in the salt supply device flows through the resin layer in the water softening device from bottom to top, so that the purposes of cleaning and ion exchange are achieved. When the multi-way valve 100 is positioned at the water replenishing station, raw water enters the salt supplying device to replenish water for the salt supplying device. When the multi-way valve 100 is positioned at the forward washing station, raw water flows through the resin layer of the water softening device from top to bottom, the fluffy resin layer is slowly precipitated under the action of water pressure, and dirt is separated out while ions are exchanged.

During the research process, the inventor finds that the multi-way valve 100 with only five stations can only provide a high concentration of regeneration salt, so that the regeneration rate of the resin is low, and the water yield of the water softener is smaller. Moreover, the water softener lacks the function of slow washing, and the soft water treatment process is coarser. In order to improve the regeneration rate of resin and optimize the soft water treatment process, the multi-way valve 100 of the application is additionally provided with a regeneration station and a slow washing station on the basis of five stations of water supply, backwashing, regeneration, water replenishing and forward washing, and the two regeneration stations can provide two different regenerated salt concentrations, so that the resin regeneration rate is improved. The slow washing station can enable raw water to slowly wash the resin layer from bottom to top, and take away broken resin and residual dirt, so that the utilization rate of salt solution is improved.

However, the more stations the multiplex valve 100 has, the more complicated the construction thereof. Thus, to simplify the construction of the multiple-way valve 100, the present application provides a simple and functionally versatile multiple-way valve 100.

In some embodiments, the multiplex valve 100 includes a valve body 20, a spool assembly 60, and a valve stem 40. Specifically, the valve body 20 is a hollow shell structure, and the valve body 20 is provided with a valve cavity 21 with one open end. The valve core assembly 60 is accommodated in the valve cavity 21 of the valve body 20, the first axial end of the valve rod 40 extends into the valve cavity 21 and is in transmission fit with the valve core assembly 60, and the second axial end of the valve rod 40 extends out of the valve cavity 21 and is in fit with the driving unit. In this way, under the driving of the driving unit, the valve rod 40 can drive the valve core assembly 60 to switch in different states, so as to change the working positions of the multi-way valve 100 to realize different functions.

With reference to fig. 2 to 5, fig. 2 is a schematic structural diagram of a movable valve plate of a multi-way valve in an embodiment of the present application; FIG. 3 illustrates a front view of a movable plate of the multi-way valve in an embodiment of the present application; FIG. 4 is a schematic structural diagram of a fixed valve plate of the multi-way valve according to an embodiment of the present disclosure; fig. 5 shows another angle structure diagram of the stationary blade in an embodiment of the present application.

The valve core assembly 60 comprises a fixed valve plate 61 and a movable valve plate 63, and the fixed valve plate 61 is fixedly installed in the valve cavity 21 and is located at the bottom of the valve cavity 21. Above the fixed valve plate 61, the movable valve plate 63 is stacked, and the first axial end of the valve rod 40 is connected with the movable valve plate 63 in a transmission manner, and the movable valve plate 63 is driven by the driving unit to rotate relative to the fixed valve plate 61. The movable valve plate 63 is provided with a flow guide groove 634, the fixed valve plate 61 is provided with a first communicating hole 612 and a plurality of second communicating holes 614, and in the process that the movable valve plate 63 rotates relative to the fixed valve plate 61, the first communicating hole 612 can be selectively communicated with any one of the second communicating holes 614 through the flow guide groove 634, so that the valve core assembly 60 can be switched under different states.

Specifically, the fixed valve plate 61 is a disc-shaped structure, the first communication holes 612 and the plurality of second communication holes 614 are arranged at intervals in the circumferential direction of the fixed valve plate 61, and all the second communication holes 614 are located on the same side of the first communication holes 612. Specifically, in one embodiment, the first communication hole 612 is curved and extends in a sector shape along the circumferential direction of the stationary plate 61.

In this embodiment, the fixed valve plate 61 is provided with three second communication holes 614, the three second communication holes 614 are all located on the same side of the first communication hole 612, and each second communication hole 614 is circular or elliptical. It is understood that the number and shape of the second communication holes 614 are not limited, and may be set as required to meet different requirements.

The movable valve plate 63 has a disk-shaped structure substantially similar to the fixed valve plate 61, and the movable valve plate 63 has a first end surface 632 and a second end surface which are disposed opposite to each other in the thickness direction (i.e., the direction perpendicular to the bottom of the valve chamber 21). The first end surface 632 is provided with a flow guide groove 634 and a blocking portion 636, and the blocking portion 636 divides the flow guide groove 634 into a first flow guide portion 6341, a second flow guide portion 6343 and a third flow guide portion 6345 which are sequentially communicated.

The first flow guide part 6341 and the third flow guide part 6345 are disposed at an interval in the circumferential direction of the movable valve plate 63, the second flow guide part 6343 extends lengthwise in the circumferential direction of the movable valve plate 63, the two opposite ends of the second flow guide part 6343 in the circumferential direction of the movable valve plate 63 are respectively connected to the first flow guide part 6341 and the second flow guide part 6343, the blocking part 636 is located between the first flow guide part 6341 and the third flow guide part 6345, and in the radial direction of the movable valve plate 63, the blocking part 636 is located on one side of the second flow guide part 6343.

When the first end surface 632 of the movable valve plate 63 and the fixed valve plate 61 are attached to each other, an orthographic projection of the first flow guide portion 6341 on the fixed valve plate 61 may coincide with the first communication hole 612 to communicate with the first communication hole 612, and an orthographic projection of the third flow guide portion 6345 on the fixed valve plate 61 may alternatively coincide with one second communication hole 614 to communicate with the second communication hole 614. An orthogonal projection of the blocking portion 636 on the stationary plate 61 may coincide with one of the second communication holes 614 for covering the remaining second communication holes 614 between the first communication hole 612 and the second communication hole 614 communicated through the guide groove 634.

In this way, the flow guide grooves 634 on the movable valve plate 63 form a "gate" structure, water in one of the second communication holes 614 of the movable valve plate 63 can flow into the first communication hole 612 sequentially through the third flow guide part 6345, the second flow guide part 6343 and the first flow guide part 6341, and the rest of the second communication holes 614 between the mutually communicated second communication holes 614 and the first communication hole 612 are closed by the blocking part 636. Therefore, the movable valve plate 63 can rotate by a small angle relative to the fixed valve plate 61 under the driving of the valve rod 40, that is, the first communication hole 612 can be communicated with any one of the second communication holes 614 alternatively, and the rest of the second communication holes 614 between the first communication hole and the second communication hole are closed at the same time to realize the rapid switching of different stations, so that the functions of the multi-way valve 100 are enriched, the structure of the valve core assembly 60 is simplified, and the design difficulty of the multi-way valve 100 is reduced.

In an embodiment, the second diversion part 6343 is located on a side of the blocking part 636 far away from the outer edge of the movable valve sheet 63, so that the first diversion part 6341 and the third diversion part 6345 are communicated, and a projection of the second diversion part 6343 on the fixed valve sheet 61 is offset from the second communication hole 614, and the second diversion part 6343 only serves to communicate the first diversion part 6341 with the second diversion part 6343, and does not cause the second communication hole 614 which does not need to be communicated to be in a conducting state.

As a preferred embodiment, in order to match the arrangement of the first communication hole 612 and the second communication hole 614, the outer contour of the flow guiding groove 634 and the blocking portion 636 formed on the first end surface 632 is located in a virtual sector (as shown by the dotted line in fig. 3), the virtual sector bends and extends along the circumferential direction of the movable valve plate 63, and the center of the virtual sector coincides with the rotation center of the movable valve plate 63. It is understood that the shape and size of the guiding groove 634 are not limited thereto, and may be set as required to meet different requirements.

The flow guide groove 634, the first communication hole 612, and the second communication hole 614 will be described below with reference to the example where the multi-way valve 100 has a first regeneration position, a slow washing position, and a second regeneration position. It is understood that the valve core assembly 60 of the present application can also be used to realize the communication of other stations, and is not limited to the above functions. It should be noted that, in the following embodiments, a slow washing channel 616 is opened on a side surface of the fixed valve plate 61 away from the movable valve plate 63, one end of the slow washing channel 616 is communicated with one of the second communication holes 614, and the second communication hole 614 communicated with the slow washing channel 616 is located between the other two second communication holes 614. The slow washing passage 616 is used to communicate with a raw water inlet, and raw water flowing from the raw water inlet may flow into the second communication hole 614 through the slow washing passage 616.

The first communication hole 612 is used for communicating the water softening device, among the three second communication holes 614, the second communication hole 614 closest to the first communication hole 612 is communicated with one salt supply channel of the salt supply device, the second communication hole 614 farthest from the first communication hole 612 is communicated with the other salt supply channel of the salt supply device, and the second communication hole 614 between the two second communication holes 614 is communicated with the raw water inlet end through the slow washing channel 616 arranged on the fixed valve plate 61.

When the multi-way valve 100 is at the first regeneration position, the valve rod 40 drives the movable valve plate 63 to rotate to a first preset angle, at this time, the first flow guide part 6341 of the flow guide groove 634 is communicated with one end of the first communication hole 612 far away from the second communication hole 614, and the third flow guide part 6345 is communicated with the second communication hole 614 closest to the first communication hole 612. The brine with the first concentration flowing out of one of the salt supply channels of the salt supply device flows into the second communication hole 614 closest to the first communication hole 612, then flows into the first communication hole 612 through the third flow guide part 6345, the second flow guide part 6343 and the first flow guide part 6341 of the flow guide groove 634 in sequence, and finally flows into the resin layer in the water softening device, so that the purposes of cleaning and ion exchange are achieved.

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 a second preset angle, at this time, the first flow guide part 6341 of the flow guide groove 634 is communicated with the middle part of the first communication hole 612, the third flow guide part 6345 is communicated with the second communication hole 614 located between the two second communication holes 614, and the blocking part 636 between the first flow guide part 6341 and the second flow guide part 6343 covers the second communication hole 614 closest to the first communication hole 612 to close the second communication hole. Raw water at the raw water inlet end flows into the second communication hole 614 between the two second communication holes 614 through the slow washing passage 616 formed on the fixed valve plate 61, then flows into the first communication hole 612 through the third flow guide part 6345, the second flow guide part 6343 and the first flow guide part 6341 of the flow guide groove 634 in sequence, and finally flows into the resin layer in the water softening device to take away broken resin and residual dirt.

When the multi-way valve 100 is located at the second regeneration position, the valve rod 40 drives the movable valve plate 63 to rotate to a third preset angle, at this time, the first flow guide part 6341 of the flow guide groove 634 is communicated with one end of the first communication hole 612 close to the second communication hole 614, the third flow guide part 6345 is communicated with the second communication hole 614 farthest from the first communication hole 612, and the blocking part 636 between the first flow guide part 6341 and the second flow guide part 6343 covers the two second communication holes 614 closer to the first communication hole 612 to seal the two second communication holes. The brine with the second concentration flowing out of the second salt supply passage of the salt supply device flows into the second communication hole 614 farthest from the first communication hole 612, then flows into the first communication hole 612 through the third flow guide part 6345, the second flow guide part 6343 and the first flow guide part 6341 of the flow guide groove 634 in sequence, and finally flows into the resin layer in the soft water device, so as to achieve the purposes of cleaning and ion exchange.

In summary, under the driving of the valve rod 40, the movable valve plate 63 rotates relative to the fixed valve plate 61 to make the first communication holes 612 communicate with different second communication holes 614 alternatively, without the need for the second communication holes 614 communicating with the first communication holes 612 to be closed by the blocking portion 636 at the same time. Because the diversion trench 634 on the movable valve plate 63 forms a gate-shaped structure, the switching of the communication state can be realized only by rotating a small angle, so that the arrangement of the first communication hole 612 and the second communication hole 614 is more compact, the function of the multi-way valve 100 is enriched, the overall structure of the multi-way valve 100 is simplified, and the design difficulty of the multi-way valve 100 is reduced.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
