Description

Technical Field

[0001] The invention relates to the technical field of water purification, and in particular to a concentrated water regulating valve. Background Art

[0002] A concentrate regulating valve is connected to the water purification system (used to process raw water such as tap water into drinking water that meets human drinking standards). The concentrate regulating valve is used to receive concentrate from the water purification system and distribute the concentrate in proportion so that a portion of the concentrate returns to the water purification system for utilization, while the other portion of the concentrate is discharged.

[0003] A hole system is formed inside the concentrate regulating valve in the prior art, and the opening of the hole system is controlled by a valve core to adjust the distribution ratio of the concentrate.

[0051] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0052] An embodiment of the present invention discloses a concentrate regulating valve, which is connected to a water purification system for proportionally distributing concentrate flowing out of the water purification system, so that part of the concentrate passing through the concentrate regulating valve flows back to the water purification system to participate in the preparation of drinking water, while the other part is directly discharged.

[0053] like Figures 1 to 3 As shown, the concentrated water regulating valve includes: a valve body 10, a partition component, a valve core 40 and a driving mechanism.

[0054] The valve body 10 has a valve cavity formed inside. One end of the valve body 10 is open. The partition member is installed into the valve cavity from the open side. The open side is blocked by the end cover 13. The partition member divides the valve cavity into a first cavity 11 (the first cavity 11 is located at Figure 1 The left side of the partition member shown in FIG. 1 ) and the second chamber 12 (the second chamber 12 is located at Figure 1 to the right of the divider as shown).

[0055] The partition component is provided with a hole system 50 , both ends of which are respectively connected to the first cavity 11 and the second cavity 12 ; the valve core 40 is arranged in the second cavity 12 , and the flow cross section of the hole system 50 is changed by rotating the valve core 40 .

[0056] A water inlet 21 and a water outlet 22 are formed on the valve body 10 at an axial position corresponding to the first cavity 11 , and both the water inlet 21 and the water outlet 22 are connected to the first cavity 11 ; a drain port is formed on the valve body 10 at an axial position corresponding to the second cavity 12 , and the drain port is connected to the second cavity 12 .

[0057] The water inlet 21 is used to communicate with the concentrated water outlet of the water purification system, and the water outlet 22 is used to communicate with the concentrated water return port of the water purification system. In this way, the concentrated water flowing out of the water purification system enters the first chamber 11 through the water inlet 21, and a part of the concentrated water entering the first chamber 11 passes through the water outlet 22 and the concentrated water return port of the water purification system and flows back to the water purification system to participate in the preparation of drinking water, while the other part passes through the hole system 50 and enters the second chamber 12, and is discharged through the drain port. In addition, the flow cross section of the hole system 50 is adjusted by driving the valve core 40 to rotate through the driving mechanism, so that the flow of concentrated water passing through the hole system 50 can be adjusted, and the ratio of concentrated water discharged from the water outlet 22 to concentrated water discharged from the drain port can be changed.

[0058] The key to this embodiment is to configure the first cavity 11 to be a flat columnar cavity, that is, the inner wall of the first cavity 11 forms a flat cylindrical surface. More importantly, the water inlet 21 is extended to the first cavity 11 along the tangential direction.

[0059] The above structural features of the first chamber 11 and the water inlet 21 enable:

[0060] After the concentrate enters the first chamber 11 through the water inlet 21, the concentrate flows in rotation at a certain flow rate in the first chamber 11. This rotational flow reduces the energy (kinetic energy) loss of the concentrate in the first chamber 11, thereby causing the inner wall of the first chamber 11 and the end face of the partition component facing the first chamber 11 to be continuously flushed by the rotating concentrated water, thereby effectively preventing the concentrate from crystallizing on the inner wall of the first chamber 11 and the end face of the partition component, and in particular preventing crystallization at the end of the hole system 50 to a greater extent.

[0061] In addition, the tangential force generated by the rotational flow of the concentrated water has a greater flushing effect on the interior of the hole system 50.

[0062] In addition, the concentrated water rotates in the first chamber 11 , thereby prolonging the time the concentrated water stays in the first chamber 11 , thereby fully utilizing the flushing effect of a unit amount of concentrated water on the relevant surfaces in the first chamber 11 .

[0063] Based on the above, it can be seen that the advantages of the concentrated water regulating valve provided in this embodiment are:

[0064] By extending the water inlet 21 to the first cavity 11 along the tangential direction, the pore system 50 can be continuously flushed to a large extent, thereby effectively preventing the pore system 50 from being blocked due to crystallization, especially effectively preventing the end of the pore system 50 with a smaller hole opening from being blocked.

[0065] In some more preferred embodiments, Figure 2 As shown, the water outlet 22 is also extended to the first chamber 11 along the tangential direction, but the direction of the water outlet 22 is opposite to the direction of departure of the concentrated water in the first chamber 11. The advantage of such a setting is that if the extension direction of the water inlet 21 is the same as the departure direction of the concentrated water in the first chamber 11 or is at a certain angle to the departure direction, the concentrated water in the first chamber 11 will be subjected to a large shear force when passing through the water outlet 22, thereby causing the concentrated water flow to be turbulent and causing a large energy loss. By making the direction of the water inlet 21 opposite to the separation direction of the concentrated water in the first chamber 11, the resistance (including shear force) encountered by the concentrated water when passing through the water inlet 21 is very small, and the energy loss is very small, which makes the concentrated water continue to rotate in the first chamber 11 to a certain extent, further improving the flushing effect of the concentrated water on the walls of the first chamber 11.

[0066] In some more preferred embodiments, the direction of the water outlet 22 is opposite to the direction of the water inlet 21. That is, the water inlet 21 is located at Figure 2 The top of the water outlet 22 is shown. Figure 1 In this way, all the concentrated water entering the first chamber 11 flows through at least half of the arc, thereby reducing the energy loss of the concentrated water to a greater extent.

[0067] The hole system 50 may have a variety of structural forms. Two specific structural forms of the hole system 50 are listed below:

[0068] The first structural form (not shown in the drawings): the hole system 50 includes a plurality of through holes penetrating the partition component, the plurality of through holes are arranged circumferentially and the apertures thereof vary sequentially, and correspondingly, the valve core 40 changes the flow cross-section of the hole system 50 by opening the through holes of different apertures and closing the remaining through holes, thereby changing the ratio of concentrated water flowing out of the water outlet 22 and the discharge port 23.

[0069] The second structural form: Figure 2 As shown, the hole system 50 is an arc-shaped through groove extending in the circumferential direction and having a gradually changing cross section. The valve core 40 changes the flow cross section of the hole system 50 by opening different sections of the arc-shaped through groove and closing other sections, thereby changing the ratio of concentrated water flowing out of the water outlet 22 and the discharge port 23.

[0070] In some more preferred embodiments, the water inlet 21 and the water outlet 22 both form a contraction port 211 in the area connected to the first chamber 11. The advantage of such a configuration is that the flow rate of the concentrated water entering the first chamber 11 is increased by providing the contraction port 211, thereby improving the flushing effect of the concentrated water on the walls of the first chamber 11.

[0071] The partition member has a variety of structures. In some more preferred embodiments, the partition member is a sleeve member 30, which forms a valve disc 31 at one end of the sleeve member 30 located in the first chamber 11; the hole system 50 is opened on the valve disc 31; the valve core 40 is installed in the sleeve member 30, and the valve core 40 can be made of ceramic material; the sleeve member 30 is sealed with the valve body 10 by a sealing ring, and the sleeve member 30 can be limited to rotate by a key structure or interference fit; a sleeve retaining ring is installed in the sleeve member 30, and the sleeve retaining ring is used to limit the valve core 40 from coming out of the sleeve member 30. The advantages of setting the structure of the partition member as the sleeve member 30 and forming the above-mentioned assembly relationship between the valve core 40 and the sleeve member 30 are: the compactness of the assembly can be improved to a greater extent.

[0072] In some more preferred embodiments, the second cavity 12 is configured as a cylindrical cavity, and a step structure is defined between the second cavity 12 and the first cavity 11; an annular step is formed on the outer periphery of the sleeve-shaped component 30 to cooperate with the step structure, so as to facilitate the assembly and positioning of the sleeve-shaped component 30.

[0073] The surface of the valve disc 31 facing the first chamber 11 may be a plane or a surface having a raised portion 311 in the middle. When the raised portion 311 is provided in the middle of the surface of the valve disc 31, the hole system 50 is arranged at the outer periphery of the raised portion 311 in the radial direction. In this way, most of the concentrated water rotates and flows along the outer periphery of the raised portion 311 in the radial direction, thereby increasing the flow rate of the concentrated water and having a better flushing effect on the hole system 50.

[0074] The concentrated water flowing through the hole system 50 can flow to the second chamber 12 by means of various structural forms. In some more preferred embodiments, for example Figures 1 to 3 As shown, an end groove 41 is provided at the outer edge of the end surface of the valve core 40 facing the valve disc 31; a guide channel is formed between the end groove 41 and the second chamber 12, and the guide channel includes an annular guide groove 42 provided on the outer peripheral surface of the valve core 40 and a guide channel 32 provided on the sleeve-shaped component 30. The end groove 41 extends axially to penetrate the annular guide groove 42; one end of the guide channel 32 penetrates the inner wall of the sleeve-shaped component 30 and is axially opposite to the annular guide groove 42, and the other end of the guide channel 32 penetrates the end surface of the sleeve-shaped component 30 located in the second chamber 12. In this way, the concentrated water flowing through the hole system 50 passes through the end groove 41, the annular guide groove 42 and the guide channel 32 in sequence to enter the second chamber 12, and is discharged through the discharge port 23. In addition, by rotating the valve core 40, the overlapping area of ​​the end groove 41 and the hole system 50 can be changed, thereby changing the flow cross section that limits the concentrated water flow.

[0075] In some more preferred embodiments, the cross-sectional area of ​​the end groove 41 is made larger than the cross-sectional area of ​​the hole system 50 corresponding to the end face, so that the flow rate of the concentrated water flowing through the hole system 50 is slowed down after entering the end groove 41, which is bound to reduce the impact of the concentrated water on related components, thereby reducing noise and vibration.

[0076] In some more preferred embodiments, a section of the flow guide channel 32 close to the second chamber 12 forms a bell mouth, which also slows down the flow rate of the concentrated water flowing through the flow guide channel 32, thereby reducing noise and vibration to a certain extent.

[0077] The driving mechanism may drive the valve core 40 in various ways. For example, the driving mechanism may drive the valve core 40 via a servo motor.

[0078] In a preferred embodiment, if Figure 1As shown, the knob 63 mechanism 60 is selected as the driving mechanism. The knob 63 mechanism 60 includes a shaft system and a knob 63. The shaft system includes a shift column 61 and a shaft rod 62. Specifically, the head of the shift column 61 is connected to the valve core 40 through a spline, and a spring top ball 64 is provided between the outer periphery of the shift column 61 and the end cover 13; the head of the shaft rod 62 passes through the end cover 13 and is connected to the tail of the shift column 61, and two sealing rings are provided between the shaft rod 62 and the end cover 13; the knob 63 is connected to the tail of the shaft rod 62. In this way, the valve core 40 can be driven to rotate by turning the knob 63.
