Description

Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to a dual regeneration mode control valve. Background Technology

[0002] The control valve of a water softener is its core component. Through the movement of the valve core assembly, it changes the direction of water flow within the valve body, enabling functions such as contact between raw water and resin, output of softened water, resin regeneration, and wastewater discharge. Based on user-set parameters such as raw water hardness and regeneration time, it automatically initiates the regeneration program, sequentially completing backwashing, brine absorption, forward washing, and water replenishment to restore the resin's softening function.

[0003] The main control valves of a water softener include: Valve body: This is the main part of the control valve, usually made of engineering plastics or lead-free brass, and has multiple water channels inside to guide the flow and distribution of water.

[0004] Piston or valve core assembly: It is movable inside and can switch different water paths by changing its position to realize various working states of the water softener, such as running, backwashing, brine suction, forward washing, water replenishment, etc.

[0005] Drive unit: Generally a small motor drives the camshaft or piston to move, thereby realizing the switching action of the valve core assembly, so that the water softener can automatically regenerate according to the preset program.

[0006] Control circuitry includes controllers such as microcontrollers and PLCs, which are used to control the actions of the drive devices according to user-defined parameters and programs, thereby achieving automated control of the water softener.

[0007] Salt valve: Installed on the control valve and connected to the salt tank, during the salt absorption and regeneration stage, after the brine is absorbed, the float inside the salt valve falls freely to block the salt absorption inlet, preventing air from being drawn into the resin tank, thus playing the function of preventing air absorption; during the water replenishment stage, the float's height is adjusted through the external float level control function of the salt valve to control the maximum amount of dissolved salt replenished, thereby controlling salt consumption.

[0008] The downstream regeneration process includes: Backwashing: After the resin has failed, backwash water is used to backwash the resin from bottom to top to remove suspended solids and broken resin trapped in the resin layer. At the same time, the resin is broken up and loosened so that the regeneration salt solution can be evenly distributed.

[0009] Regeneration: After backwashing, the regeneration solution (such as brine) enters from the top of the exchanger and reacts with calcium, magnesium and other ions in the resin layer to restore the resin's exchange capacity.

[0010] Forward wash: After regeneration is completed, a forward wash is required.

[0011] The countercurrent regeneration process includes: Mini backwash: Before regeneration, backwash water enters from the bottom of the exchanger and flows upward through the resin layer to loosen and clean it initially. This removes some suspended impurities, prevents the resin layer from clogging, and creates favorable conditions for subsequent regeneration.

[0012] Introducing the regenerant: After a small backwash, the regenerant enters from the bottom of the exchanger, flows upward through the resin bed, and fully contacts the resin to regenerate it. Because the regenerant first enters the lower resin bed, this portion of the resin can react fully with the higher concentration of the regenerant, achieving a higher degree of regeneration. As the regenerant flows upward, its concentration gradually decreases, but the concentration of the regenerant in contact with the upper resin bed remains relatively high, resulting in a better regeneration effect.

[0013] Displacement cleaning: After the regenerated liquid has been introduced, softened water continues to be introduced at a certain flow rate from the bottom of the exchanger, flowing upward through the resin layer to further displace the residual regenerated liquid and impurities generated in the resin.

[0014] Mini-wash: After the replacement cleaning is completed, close the inlet valve and the regenerated liquid valve, and open the drain valve at the bottom of the exchanger to perform a mini-wash. Softened water enters from the top of the exchanger and flows downward through the resin layer to further clean the impurities remaining in the resin layer until the effluent is clear.

[0015] Large backwash (optional): A large amount of backwash water enters from the bottom of the exchanger and flows upward through the resin bed, strongly impacting and agitating the resin bed, causing the resin particles to loosen and rub against each other, removing deep impurities and dirt from the resin bed. The large backwash has a longer time and a higher flow rate, which can effectively restore the cleanliness of the resin bed, but it may cause the resin bed to become disordered, requiring readjustment of the resin bed structure.

[0016] Final Wash: After the initial wash, a final wash is required.

[0017] The existing water softener control valves have the following defects; 1. To enable the switching between co-current and counter-current regeneration, the control valve of the existing water softener needs to have its internal structure modified or the siphon position changed.

[0018] 2. Existing water softener control valves use current monitoring or Hall effect magnetic induction to determine the reference point.

[0019] 3. Existing water softener control valves generally use bypass valves to bypass hard water, which cannot accurately adjust the hardness of the water at the outlet.

[0020] 4. The pistons used in the control valves of existing water softeners are mostly made of metal coated with Teflon, and the Teflon coating does not comply with the new PFAS standards in Europe and the United States.

[0021] 5. Most existing water softener control valves use flow meters that offer suitable cost and accuracy. Utility Model Content

[0054] First, it needs to be explained that Figure 1 The arrangement of the various mating and fixing components (such as pins, bolts, etc.) and the positions of the water inlets on the valve body are not the focus of this invention. The mating and fixing components can be implemented using existing structures. The positions of the water inlets on the valve body can be determined according to the actual shape of the valve body, as long as the different relative positions of the grille assembly and the valve core assembly can cooperate with the water inlets to form the required flow channels / water paths, this invention can be realized.

[0055] First embodiment; This utility model provides a dual regeneration mode control valve, comprising: A drive assembly for driving the valve core assembly to reciprocate within the valve body assembly; The bar assembly 12 is fixed in the valve body assembly and consists of multiple bars, each bar corresponding to a different water inlet of the water purification equipment. The valve core assembly includes a flow valve core 8 and a salt valve core, with one end of the flow valve core 8 connected to the drive assembly and the other end connected to the salt valve core; The valve core assembly stops at different positions of the bar assembly 12, and the flow valve core 8 opens the corresponding water outlet while blocking the other water outlets to form different water paths; Salt valve cores, including replaceable co-current salt valve core 9 and counter-current salt valve core 10; refer to Figure 2 As shown, when performing co-current regeneration, install the co-current salt valve core 9, use the plug 22 to block the counter-current regeneration inlet, and the co-current salt valve core 9 stops moving to open the co-current regeneration water path; See details Figures 13 to 17 As shown, this utility model operates under various conditions when using the co-current salt valve core 9.

[0056] When performing countercurrent regeneration, install the countercurrent salt valve core 10, use the plug 22 to block the cocurrent regeneration inlet, and stop the movement of the countercurrent salt valve core 10 to open the countercurrent regeneration water path.

[0057] See details Figures 18 to 22 As shown, this utility model operates under various conditions when using the counterflow salt valve core 10.

[0058] Preferably, the valve core assembly is manufactured by PEEK molding.

[0059] Second embodiment; refer to Figure 1 As shown, a further improvement to the dual regeneration mode control valve of the first embodiment described above includes: The mixing component 13 is formed on the original water path and controls the mixing volume by changing the water surface area of ​​the original water path.

[0060] Third embodiment; refer to Figure 1 As shown, this utility model provides a drive assembly for the dual regeneration mode control valve of the first embodiment described above, comprising: Motor 1, whose output end meshes through the upper end of the transmission component 5 of the motor mounting bracket 4, and its forward and reverse rotation drives the pull rod of the transmission component 5 to move up and down. The first infrared sensor 2 is fixed on the motor mounting bracket 4. It is used to record the gear rotation angle and outputs a signal to the PCB 6. The second infrared sensor 3 is fixed on the motor mounting bracket 4 and is used to position the pull rod at its initial position. Its output signal is sent to the PCB 6. The first infrared sensor 2 and the second infrared sensor 3 form a beam-to-beam relationship. The motor mounting bracket 4 is fixed on the controller bracket 7; Transmission assembly 5, which is fixed on controller bracket 7; PCB6 is fixed on the controller bracket 7.

[0061] For example, refer to Figures 3-7 As shown, the transmission assembly 5 includes: The large gear 51 has teeth 511 formed on its lower outer periphery and an upward hollow cylindrical extension 512 formed at its axial center. The cylindrical extension 512 has internal threads and a plug hole 515 is formed on the side wall of the cylindrical extension 512. The spherical plug 52 blocks the plug hole 515 to prevent the spherical ball 53 from falling out; Multiple first light-transmitting grooves 514 are evenly distributed between the large gear 51 and the hollow columnar extension 512; The first spherical groove 513 is formed in the hollow columnar extension 512; The gear fixing shaft 54 ​​is formed as a hollow structure, and its upper part is inserted into the hollow cylindrical extension 512; A limiting boss 541 is formed on the upper inner sidewall of the through hole 542 at the center of the gear fixing shaft 54; The second spherical groove 543 is formed on the upper part of the outer side wall of the gear fixed shaft 54, and its position corresponds to that of the first spherical groove 513; Anti-rotation boss 544 is formed on the lower part of the outer side wall of gear fixing shaft 54; A pin hole 545 is formed on the lower part of the outer side wall of the gear fixing shaft 54; The sphere 53 connects the gear fixed shaft 54 ​​and the large gear 51 together. The large gear can rotate but cannot move axially. A pull rod 55 has its upper part inserted into a through hole 542, and its upper sidewall has a thread 553, which engages with the internal thread of the columnar extension 512. A limiting groove 551 is formed on the upper side wall of the pull rod 55 and is engaged in the limiting boss 541; The second light-transmitting groove 552 is formed on the upper side wall of the pull rod 55.

[0062] During operation, the motor drives the large gear to rotate, which in turn moves the pull rod up and down, thus changing the position of the controller. One revolution of the large gear corresponds to a movement of one tooth pitch in the pull rod. A reflective infrared sensor emits infrared light. When this light passes through the first light-transmitting slot of the large gear, hits the reflective plate on the opposite side, and is reflected back to the reflective infrared sensor, the sensor sends a signal. This signal is transmitted to the control PCB. The control PCB records a pulse, and the number of pulses is converted into the distance the pull rod moves up or down. When the pull rod moves upward, and the infrared light from the through-beam infrared sensor just passes through the second light-transmitting slot of the pull rod, the through-beam infrared sensor sends a signal. The control PCB receives this signal and issues a command for the pull rod to return to its initial position. The position of the controller's pull rod is always based on this initial position. The accuracy of the external light source ensures precise control of the initial position.

[0063] Fourth embodiment; This utility model provides a valve core assembly that can be used in the dual regeneration mode control valve of the first embodiment above. The flow valve core 8 is formed as a variable cross-section column with large diameters at both ends and small diameter in the middle. Its small diameter section can be aligned with different water outlets on the valve body through axial displacement to form different water flow paths. At the same time, its first large diameter section and second large diameter section can block the remaining passages on the valve body.

[0064] refer to Figure 1 Combination Figure 8 As shown, the co-current salt valve core 9 is formed as a variable cross-section column with a large diameter at both ends and a small diameter in the middle. During co-current salt intake, both salt intake and water replenishment pass through the position with the smaller diameter in the middle of the co-current salt valve core 9 (forming a groove).

[0065] refer to Figure 1 Combination Figure 9 As shown, the counter-current salt valve core 10 is formed as a variable cross-section column with large diameters at both ends and a small diameter in the middle. It has two small diameter sections and a large diameter section between the two small diameter sections. During counter-current salt intake, salt intake / water replenishment passes through two different small diameter positions (forming two grooves) of the counter-current salt valve core 10. Salt intake is from the first groove (closer to the small diameter position of the flow valve core 8), and water replenishment is from the second groove (relatively farther away from the small diameter position of the flow valve core 8).

[0066] Fifth embodiment; This utility model provides a flow meter that can be used in the dual regeneration mode control valve of the first embodiment described above. The flow meter is installed in the flow meter mounting part of the valve body; see reference. Figure 10 , Figure 11 As shown, the flow meter includes: The main body 16.1 is formed in a shape that is compatible with the valve body flow meter mounting part 16.2, and can be inserted and fixed to the valve body flow meter mounting part 16.2; Impeller mounting portion 16.3 is formed on the top of body 16.1 and is used to mount impeller assembly 16.4; The annular magnet 16.5 is fitted into the first recess 16.6 at one end of the impeller assembly 16.4 that is inserted into the impeller mounting portion 16.3, and it does not contact the impeller mounting portion 16.3; The Hall element 16.7 is installed in the Hall element mounting portion 16.8 of the main body 16.1.
