Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of water treatment equipment, and particularly relates to a water treatment multi-way softener. BACKGROUND

[0002] Softened water refers to natural water containing a small amount of soluble magnesium salt and calcium salt, or hard water treated by softening. The softened water is suitable for a wide range of fields such as bathroom, kitchen, laundry, heating, boiler, central air conditioning equipment water supply, etc. The main function of the softener is to reduce the hardness of water by adsorbing calcium and magnesium ions in the water in the ion exchange resin. The principle is that the sodium ions contained in the resin exchange with calcium ions and magnesium ions in the water. However, when the resin is saturated, it will be invalid, and needs to be regenerated and activated. The regeneration liquid uses sodium chloride (salt), and the salt solution (sodium chloride solution) is taken from the salt tank into the resin layer of the softened water equipment to replace the calcium and magnesium ions of the resin, which are discharged through the waste water during backwashing, so that the resin restores its original exchange capacity. Therefore, the softener usually needs to have the functions of softening, backwashing, salt regeneration, salt tank water replenishment, and forward flushing.

[0003] The patent with the application number CN202220651806.7 discloses a double-valve-body softening valve, which comprises a valve body, an inlet and outlet water unit and a regeneration unit arranged in the valve body. The valve body is provided with a first valve cavity and a second valve cavity connected thereto. The inlet and outlet water unit is arranged in the first valve cavity, and the regeneration unit is arranged in the second valve cavity. The first valve cavity comprises a first, second and third cavity, and the second cavity is further divided into a first and second water outlet cavity. The third cavity is further divided into a first and second fan-shaped cavity. The second valve cavity comprises nine cavities. The inlet and outlet water unit comprises a first driving device, a first movable valve piece and a first fixed valve piece. The normal water outlet function and temporary plugging function are realized by cooperation of the first movable valve piece, the first fixed valve piece and the plurality of cavities in the first valve cavity. The regeneration unit comprises a second driving device, a second movable valve piece and a second fixed valve piece. The forward washing, backwashing, regeneration and water injection functions are realized by cooperation of the second movable valve piece, the second fixed valve piece and the nine cavities in the second valve cavity.

DETAILED DESCRIPTION

[0061] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application, and those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0062] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0063] Example 1 of the multi-channel water softener provided by the present invention:

[0064] like Figure 1 As shown, the water treatment multi-port water softener includes a first valve body 1, a second valve body 2, and a double-layer pipe 3, which are injection molded together. Multiple support legs 46 are detachably connected to the first valve body 1 to support and install the water treatment multi-port water softener on the side of the treatment tank.

[0065] like Figure 2 and Figure 3 As shown, the first valve body 1 is equipped with an inlet 4, an outlet 5, an upper tank connection port 8, and a lower tank connection port 9. The inlet 4 and outlet 5 are located on the lateral sides of the first valve body 1, with their axes coinciding. The upper tank connection port 8 and lower tank connection port 9 are located on the longitudinal sides of the first valve body 1, with their axes coinciding and perpendicular to the axes of the inlet 4 and outlet 5. This design provides ample installation space at the first valve body 1, making installation more convenient. The upper tank connection port 8 is connected to the upper inlet of the tank via a pipe, and the lower tank connection port 9 is connected to the lower outlet of the tank via a pipe. Figure 2 As shown, the water pipe at the lower connection port 9 of the tank extends to the outside of the double-layer pipe 3, and multiple supporting ribs are provided between the water pipe and the double-layer pipe 3 to ensure a firm connection between the double-layer pipe 3 and the first valve body 1.

[0066] like Figure 3 and Figure 9 As shown, the first valve body 1 has a first valve inner cavity and a first valve outer cavity 14 arranged coaxially, with the first valve outer cavity 14 communicating with the water inlet 4. The inner cavity wall of the first valve has an outlet port 19 corresponding to the outlet 5 and an inlet port 18 corresponding to the inlet 4. A straight partition 49 is provided in the inner cavity of the first valve, which divides the space within the inner cavity into a first chamber 16 and a second chamber 17 that are not interconnected. Figure 10 and Figure 12 As shown, the first chamber 16 is connected to the connecting port 8 on the tank body, as... Figure 11 and Figure 12 As shown, the second chamber 17 is connected to the lower connecting port 9 and the outlet 5 of the tank. The center of the straight partition 49 has a protrusion, on which a first fixed valve plate 12 is fitted and fixed, as shown. Figure 5As shown, the first fixed valve plate 12 is an integral structure, including a ring beam 53 and a cross-shaped partition beam 50 arranged at the center of the ring beam 53, and the center of the cross-shaped partition beam 50 is provided with a circular hole, which is exactly sleeved on the protrusion of the straight-shaped partition plate 49, so as to realize the fixation of the first fixed valve plate 12 in the first valve inner cavity, and at this time, the cross-shaped partition beam 50 is in contact with the straight-shaped partition plate 49. The cross-shaped partition beam 50 divides the space in the ring beam 63 into two first water passing holes 51 communicating with the first chamber 16 and two second water passing holes 52 communicating with the second chamber 17.

[0067] The first fixed valve plate 12 is provided with a rotating sealing assembly of the first movable valve plate 13, and when the first movable valve plate 13 rotates, the first fixed valve plate 12 can play a role in lubricating the first movable valve plate 13. As shown, Figure 4 and Figure 6 As shown, the first movable valve plate 13 is a columnar integral structure, and two sealing grooves 54 are arranged in the circumferential direction of the first movable valve plate 13, and each sealing groove 54 is clamped with a sealing pad 55, and the two sealing grooves 54 are distributed on the diametrically opposite sides of the first movable valve plate 13. A cross-shaped partition plate 56 is arranged between the two sealing grooves 54 on the first movable valve plate 13, and the cross-shaped partition beam 50 of the first fixed valve plate 12 is in frictional contact with the cross-shaped partition plate 56 on the first movable valve plate 13. The cross-shaped partition plate 56 extends along the axial direction of the first movable valve plate 13 to the end face of one side of the first movable valve plate 13 in the axial direction, and the longitudinal plate segment part of the cross-shaped partition plate 56 divides the space between the two sealing grooves 54 into two water passing channels that are not communicated with each other, and the transverse plate segment part of the cross-shaped partition plate 56 further divides the two water passing channels into two first water passing channels 38 and two second water passing channels 39 that are separated from the two first water passing channels 38, and the two first water passing channels 38 are separated from each other in the longitudinal direction of the first valve body 1, and the two second water passing channels 39 are separated from each other in the longitudinal direction of the first valve body 1. The first water passing channel 38 and the second water passing channel 39 both extend along the outer circumference of the first movable valve plate 13.

[0068] The second valve body 2 is provided with a blowdown port 10, and the second valve body 2 has a second valve inner cavity and a second valve outer cavity 15, as shown, Figure 9 As shown, the second valve body 2 and the first valve body 1 have a part that is partially overlapped when being formed, and a valve body communication port 20 is arranged on the part to communicate the first valve outer cavity 14 with the second valve outer cavity 15. As shown, Figure 3 As shown, the second valve inner cavity includes a central blowdown cavity 32 arranged coaxially and a working cavity 27, a backwashing cavity 28, a water passing cavity 30, a regeneration cavity 29 and a forward washing cavity 31 arranged in sequence counterclockwise along the circumferential direction of the central blowdown cavity 32, and the central blowdown cavity 32 communicates with the blowdown port 10. As shown, Figure 10As shown, a second fixed valve plate 47 is fixed above the inner cavity of the second valve, and a second moving valve plate 48 is rotatably sealed above the second fixed valve plate 47. The second fixed valve plate 47 lubricates the second moving valve plate 48 when it rotates.

The working blind plate 33 blocks the working chamber 27.

[0070] by Figures 14-21 The view shown is in the direction of the counterclockwise rotation of the second moving valve plate 48, such as Figure 8 As shown, the second moving valve plate 48 is provided with a central drain blind groove 40 arranged coaxially and an inlet notch 43, a first blind groove 41, a drain guiding blind groove 42, and a second blind groove 44 arranged in a counterclockwise sequence along the circumference of the central drain blind groove 40. Among them, the drain guiding blind groove 42 is connected to the central drain blind groove 40, and the first blind groove 41 and the second blind groove 44 are arranged opposite to each other.

[0071] In this embodiment, combined with Figure 3 , Figure 7 and Figure 8 It can be seen that the second valve body 2, the second fixed valve plate 47, and the second moving valve plate 48 are all designed based on a five-part structure. The number of corresponding chambers in the second valve body 2, the number of corresponding through holes on the second fixed valve plate 47, and the number of corresponding blind grooves on the second moving valve plate 48 are relatively small, resulting in a simpler overall structure, a larger water passage area, and a significant softening effect. For example, Figure 8 As shown, the central angle corresponding to the inlet notch 43 is 72°, the central angle corresponding to the drain guide blind groove 42 is 72°, the central angle corresponding to the first blind groove 41 is 144°, and the central angle corresponding to the second blind groove 44 is 72°. The central angles corresponding to the working chamber 27, backwash chamber 28, water passage chamber 30, regeneration chamber 29, forward wash chamber 31, working blind plate 33, backwash through hole 34, water passage through hole 36, regeneration through hole 35, and forward wash through hole 37 are all 72°.

The first drive device 6 and the second drive device 7 are independent of each other. They drive the first moving valve plate 13 and the second moving valve plate 48 to rotate respectively through corresponding gears and transmission rods. This part of the structure is the prior art and will not be described in detail here.

The first flow channel 21 is communicated with a regeneration cavity 29, the second flow channel 22 is provided with a jet flow device 25 connected with the salt suction port 11, a check valve 26 is arranged at the inlet of the jet flow device 25, the double-layer pipe 3 is provided with the salt suction port 11 at the position corresponding to the jet flow device 25, and a valve is connected with the salt suction port 11. The valve can be an electric valve. The water flowing out of the first flow channel 21 can flow to the inlet of the jet flow device 25 at the second flow channel 22. The second flow channel 22 and the fourth flow channel 24 are both communicated with a forward washing cavity 31, and the third flow channel 23 is communicated with a backwashing cavity 28 and a water passing cavity 30. The third flow channel 23 and the fourth flow channel 24 both extend to the cavity wall of the first valve inner cavity, so that the third flow channel 23 is communicated with the second cavity 17 and the fourth flow channel 24 is communicated with the first cavity 16.

[0074] When the water is normally produced, as shown in Figure 14 and Figure 15 , the first valve body 1 is in a working state, one of the sealing pads 55 blocks the third flow channel 23 and the fourth flow channel 24, the two first water passing channels 38 are opposite to the water inlet communication port 18 and are communicated with the first cavity 16, the two second water passing channels 39 are opposite to the water outlet communication port 19 and are communicated with the second cavity 17, and the water inlet gap 43 is shielded by the working blind plate 33. At this time, the flow path of the raw water is: the water inlet 4→the first valve outer cavity 14→the water inlet communication port 18→the first water passing channel 38→the first water passing hole 51→the first cavity 16→the upper tank communication port 8 of the treatment tank body→the treatment tank body→the lower tank communication port 9 of the treatment tank body→the second cavity 17→the second water passing hole 52→the second water passing channel 39→the water outlet communication port 19→the water outlet 5.

[0075] When the water quality is unqualified, the first driving device 6 drives the first valve disc 13 to rotate counterclockwise by 90° (of course, it can also rotate counterclockwise by 270°, or clockwise by 90° or 270°, and the counterclockwise rotation by 90° is taken as an example in the embodiment), so that the two sealing pads 55 block the water outlet communication port 19 and the water inlet communication port 18 respectively, and the first valve body 1 is in a blocking state, and the second valve body 2 can enter a cleaning process. In this way, the water outlet 5 does not need to be provided with a valve to be opened and closed, and only the sealing pad 55 on the first valve disc 13 can achieve this, thereby saving the cost. The second driving device 7 drives the second valve disc 48 to rotate counterclockwise by a corresponding angle in sequence, so that the second valve body 2 can realize the functions of backwashing, regeneration and forward washing.

[0076] Specifically, when the second moving valve plate 48 is rotated 72° counterclockwise compared to its position when the first valve body 1 is in normal water production, the second valve body 2 is in a backwashing state, such as... Figure 16 and Figure 17 As shown. At this time, the water passage chamber 30 and the regeneration chamber 29 are blocked by the first blind groove 41, and the sewage discharge guide blind groove 42 corresponds to the forward washing chamber 31. When the second valve body 2 is in the backwash state, the flow path of the raw water is as follows: inlet 4 → first valve outer cavity 14 → valve body connecting port 20 → second valve outer cavity 15 → inlet notch 43 → backwash through hole 34 → backwash chamber 28 → third flow channel 23 → second water passage channel 39 near the outlet 5 → second chamber 17 → tank lower connecting port 9 → treatment tank → tank upper connecting port 8 → first chamber 16 → second water passage channel 39 near the inlet 4 → fourth flow channel 24 → forward washing chamber 31 → forward washing through hole 37 → sewage discharge guide blind groove 42 → central sewage discharge chamber 32 → sewage discharge port 10.

[0077] Compared to its position when the first valve body 1 is in normal water production, when the second moving valve plate 48 rotates 216° counterclockwise, the second valve body 2 is in a regeneration state, such as... Figure 18 and Figure 19 As shown, at this time, the first blind channel 41 blocks the forward washing chamber 31, the second blind channel 44 blocks the water passage chamber 30, the sewage discharge guide blind channel 42 corresponds to the backwash chamber 28, and the check valve 26 at the inlet of the ejector 25 and the valve at the brine suction port 11 are both open. Raw water enters the outer cavity 14 of the first valve from the inlet 4, and enters the outer cavity 15 of the second valve from the valve body connecting port 20. After passing through the regeneration through hole 35 and the regeneration chamber 29 in sequence from the inlet gap 43, it flows into the first flow channel 21 and flows towards the ejector 25. At this time, the ejector 25 sucks salt from the brine suction port 11. The brine regeneration agent sucked by the ejector 25 enters the second flow channel 22, mixes with the raw water, and flows into the fourth flow channel 24. It then passes through the second through hole near the inlet 4. Water enters the first chamber 16 through channel 39, and then flows into the treatment tank through the upper connecting port 8 and the upper inlet of the treatment tank. It then flows out through the lower outlet of the treatment tank, enters the second chamber 17 through the lower connecting port 9, and then enters the third flow channel 23 through the second water passage 39 near the outlet 5. Finally, it flows through the backwash chamber 28, the backwash through-hole 34, and the drain guide blind channel 42 into the central drain chamber 32, and is discharged from the drain port 10. After regeneration, the valve at the brine suction port 11 is closed. When replenishing the brine tank, the valve at the brine suction port 11 is opened during the forward wash period. The brine tank is replenished with water at the set time, which is shorter than the forward wash time.

[0078] Compared to its position when the first valve body 1 is in normal water production, when the second moving valve plate 48 is rotated 288° counterclockwise, the second valve body 2 is in the forward washing state, such as... Figure 20 and Figure 21The first blind groove 41 blocks the backwashing cavity 28, the second blind groove 44 blocks the regeneration cavity 29, and the pollution discharge guide blind groove 42 corresponds to the water passing cavity 30. When washing, the flow path of the raw water is: the water inlet 4→the first valve outer cavity 14→the valve body communication port 20→the second valve outer cavity 15→the water inlet gap 43→the washing-through hole 37→the washing cavity 31→the fourth flow channel 24→the second water passing channel 39 close to the water inlet 4→the first cavity 16→the upper communication port 8 of the tank body→the processing tank body→the lower communication port 9 of the tank body→the second cavity 17→the second water passing channel 39 close to the water outlet 5→the third flow channel 23→the water passing cavity 30→the water passing-through hole 36→the pollution discharge guide blind groove 42→the central pollution discharge cavity 32→the pollution discharge port 10. In this state, the second dynamic valve plate 48 continues to rotate counterclockwise by 72° and resets.
