Description

Concentrated water distribution proportion regulating valve
Technical Field
The invention relates to the technical field of water purification, in particular to a concentrated water distribution proportion adjusting valve.
Background
In a water purification system, in order to reduce the concentration difference degree of liquid concentration in the concentrated water side of a filter membrane piece and ensure that the flow and the flow speed of liquid flowing through the filter membrane piece are large enough, the concentrated water is generally divided into two paths by two flow regulating valves connected in parallel, one path is used as waste water to be discharged, the other path is returned and mixed with tap water to be supplied to the filter membrane piece again, and then the flow and the flow speed of the liquid flowing through the concentrated water side are large enough and the discharge amount of the concentrated water can also be reduced.
However, when the flow regulating valve is used for distributing concentrated water in a large proportion, the precision of the flow regulating valve for controlling the proportion of the concentrated water is low, and the control difficulty is high. The reason why the control accuracy is low is that: in order to meet the requirement of large-proportion distribution, the flow regulating valve needs to set the ratio of the cross sections of two valve holes for distributing the concentrated water to be large, namely, one of the two valve holes is a large hole, and the other valve hole is a small hole, and the influence degree of factors such as concentrated water viscosity, particle attachment, pressure and the like is larger because the smoothness of the concentrated water passing through the valve holes is reduced along with the cross section, so that the larger the ratio of the cross sections of the valve holes is, the larger the difference between the actual distribution ratio of the distributed concentrated water and the preset distribution ratio of the concentrated water (the preset distribution ratio is calculated according to hydromechanics and is obtained based on the through-flow cross section defined by the two valve holes) is. Specifically, for example, the degree of influence of the adhesion of particles in the concentrated water to the small holes on the size of the through-flow cross section defined by the small holes is greater, which in turn causes the distribution ratio of the concentrated water to be out of order; for another example, at a higher concentrate viscosity, a pressure drop on the concentrate side has a greater effect on the flow rate of concentrate through the small holes, resulting in a greater rate of decrease in the flow rate of concentrate through the small holes than the flow rate of concentrate through the large holes; for another example, at lower pressures, viscosity has a greater effect on the flow of concentrate through the small pores than the flow of concentrate through the large pores.
In addition, the different damping that two parts of thick water receive in the process of passing through flow control valve also causes the influence to the control of the distribution proportion of thick water.

1. the concentrated water in the liquid inlet cavity is made to rotate, and the valve hole with the smaller section is closer to the edge (the radial position with the large center distance), so that the influence of the attachment of the particulate matters on the control precision of the distribution ratio under the requirement of the large distribution ratio is reduced. Specifically, in the region that is close to the edge more, the velocity of flow of the concentrated water that is rotary motion is bigger, and this makes the scouring action of concentrated water to the valve opening that the cross-section is littleer more, and then can prevent effectively that the particulate matter from attaching to in small cross-section valve opening department, and then can effectively reduce the size influence degree of particulate matter to the through-flow cross-section that small cross-section valve opening was prescribed a limit to, and then can effectively improve the control accuracy to the distribution ratio regulation under big distribution ratio requires.

3. The concentrated water in the liquid inlet cavity is enabled to rotate, and the valve hole with the smaller cross section is enabled to be closer to the edge, so that the influence of the viscosity of the concentrated water on the control precision of the distribution ratio under the requirement of a large distribution ratio is favorably reduced. Specifically, because the pressure of the concentrated water passing through the valve hole with the small cross section is large, the influence of the viscosity of the concentrated water on the flow rate of the concentrated water passing through the valve hole with the small cross section can be counteracted to a certain degree by increasing the pressure, and the control precision of the distribution ratio adjustment under the requirement of a large distribution ratio is further improved.
4.

The embodiment of the invention discloses a concentrated water distribution proportion regulating valve which is used for dividing concentrated water flowing out from a concentrated water side of a filter membrane piece into two paths so that one part of concentrated water can be mixed with tap water to be re-supplied to the filter membrane piece, and the other part of concentrated water is discharged.
As shown in fig. 1 to 4, the regulator valve includes: a valve body 10, a valve seat 20, and a first control mechanism 31 and a second control mechanism 32.
A liquid inlet 11 and two liquid outlets are formed on the periphery of the valve body 10, and the liquid inlet 11 is located at the axial middle position of the two liquid outlets; the liquid inlet 11 is used for being communicated with a water outlet of a concentrated water side of the filter membrane piece, so that the concentrated water on the concentrated water side can enter the valve body 10 through the liquid inlet 11; one of the two outlets is used for discharging concentrated water, and the other is used for being mixed with tap water and then being re-supplied to the filter membrane element, so that the outlet for guiding the concentrated water to be mixed with the tap water is referred to as a first outlet 121, and the outlet for discharging the concentrated water is referred to as a second outlet 122.
In some preferred embodiments, the inlet port 11, the first outlet port 121 and the second outlet port 122 are arranged on the same side of the valve body 10, i.e. the inlet port 11, the first outlet port 121 and the second outlet port 122 are located at the same circumferential position.
A valve seat 20 is provided in the valve body 10, the valve seat 20 being a member for dividing the concentrated water entering into the valve body 10 from the liquid inlet 11 into two paths, specifically, the valve seat 20 includes a valve housing 21 and a first valve plate 221 and a second valve plate 222; the valve sleeve 21 is arranged at an axial position corresponding to the liquid inlet 11, and an inner hole of the valve sleeve 21 is arranged in a cylindrical shape; the first valve plate 221 and the second valve plate 222 are disposed in a cylindrical inner hole of the valve housing 21, and the first valve plate 221 and the second valve plate 222 are disposed opposite to each other at an interval, so that the first valve plate 221, the second valve plate 222 and the valve housing 21 together enclose a cylindrical liquid inlet cavity 24 (or a cylindrical cavity).
An inlet which is communicated with the liquid inlet cavity 24 and is tangent to the liquid inlet cavity 24 is formed in the sleeve wall of the valve sleeve 21, and is named as a tangential inlet 25 for convenience of understanding; the tangential inlet 25 communicates with the loading port 11. In this way, the concentrated water entering the valve body 10 through the liquid inlet 11 enters the liquid inlet cavity 24 in a tangential flow direction under the guidance of the tangential inlet 25, and the concentrated water entering the liquid inlet cavity 24 rotates (or is called circular motion) due to the cylindrical structure of the liquid inlet cavity 24 and the tangential entering direction of the concentrated water.
The first valve plate 221 and the second valve plate 222 are each provided with a through hole system in thickness, and the hole system provided in the first valve plate 221 is referred to as a first hole system 231, and the hole system provided in the second valve plate 222 is referred to as a second hole system 232.
The first control mechanism 31 is configured to selectively open the valve holes 2311 with different cross sections in the first hole system 231, so that the liquid inlet cavity 24 is communicated with the first liquid outlet 121 through the valve holes 2311 with different cross sections in the first hole system 231, and a part of the concentrated water entering into the liquid inlet cavity 24 flows out of the first liquid outlet 121 through the valve holes 2311 of the first hole system 231 for mixing with the tap water; the second control mechanism 32 is configured to selectively open the valve holes 2321 with different cross-sections in the second hole system 232, so that the liquid inlet chamber 24 is communicated with the second liquid outlet 122 through the valve holes 2321 with different cross-sections in the second hole system 232, and another part of the concentrated water entering the liquid inlet chamber 24 passes through the valve holes 2321 of the second hole system 232 and is discharged from the second liquid outlet 122 as waste water. Thus, the distribution ratio of the two concentrated waters can be adjusted by opening the valve holes of different cross-sections in the two hole systems. For example, a substantially equivalent distribution ratio may be obtained by opening valve openings of comparable cross-sectional size in the two bore series, whereas a large distribution ratio may be obtained by opening valve openings of greater cross-sectional size in the two bore series.
In the present invention, the valve holes in the first and second hole series 231 and 232 have the following arrangement characteristics:
the valve hole 2311 of the first bore system 231 and the valve hole 2321 of the second bore system 232 are arranged in a spiral line extending outward from the radially inner portion, that is, the valve hole 2311 of the first bore system 231 and the valve hole 2321 of the second bore system 232 are circumferentially arranged and have cross sections that decrease as the center distance to the cylindrical chamber increases. That is, the smaller the cross-sectional area of the valve hole, the closer to the edge of the valve plate.
The invention can obtain the following beneficial effects by carrying out the above structure on the liquid inlet cavity 24, the inlet and the two hole systems:
1. the concentrated water in the liquid inlet cavity 24 is rotated, and the valve hole with the smaller section is closer to the edge (the radial position with the large center distance), so that the influence of the adhesion of the particulate matters on the control precision of the distribution ratio under the requirement of the large distribution ratio is favorably reduced. Specifically, in the region that is closer to the edge, the flow rate of the concentrated water that does rotary motion is bigger, and this makes the scouring action of concentrated water to the valve opening that the cross-section is littleer bigger, and then can effectively prevent that the particulate matter from attaching to in small-section valve opening department, and then can effectively reduce the size influence degree of particulate matter to the through-flow cross-section that small-section valve opening prescribed a limit to, and then can effectively improve the control accuracy to distribution ratio regulation under big distribution ratio requirement.
2. The concentrated water in the liquid inlet cavity 24 rotates, and the valve hole with the smaller cross section is closer to the edge, so that the influence of the pressure on the concentrated water side of the filter membrane part on the control precision of the distribution ratio under the requirement of large distribution ratio is favorably reduced. Specifically, the dense water that is rotary motion can produce centrifugal force, under centrifugal force and the reaction force of feed liquor chamber 24 to dense water, the pressure that is close to the dense water at edge more is big more, this makes the pressure of the dense water through the less valve opening in cross-section big more, the pressure to the dense water side has carried out the promotion of certain degree in other words, and then avoided dense water to pass through the valve opening of small cross-section under lower pressure, and then reduced the influence of the pressure of dense water side to the dense rivers volume through the small cross-section valve opening, the control accuracy of distribution ratio control under the requirement of big distribution ratio has further been improved.
3. The concentrated water in the liquid inlet cavity 24 is enabled to rotate, and the valve hole with the smaller section is enabled to be closer to the edge, so that the influence of the viscosity of the concentrated water on the control precision of the distribution ratio under the requirement of a large distribution ratio is favorably reduced. Particularly, because the pressure of the concentrated water passing through the valve hole with the small section is large, the influence of the viscosity of the concentrated water on the flow rate of the concentrated water passing through the valve hole with the small section can be counteracted to a certain degree by increasing the pressure, and the control precision of the distribution proportion regulation under the requirement of the large distribution proportion is further improved.
4. Rotatory operation is made to dense water in the feed liquor chamber 24, and the more the flow velocity of dense water that is close to the radial central point of feed liquor chamber 24 puts is less, and this makes impurity (including the particulate matter) in the dense water concentrate put the enrichment near central point, and the more the cross-section of the valve opening that is close to central point puts is big more, and then makes impurity more derive by big cross-section valve opening, and then can effectively prevent impurity enrichment in small cross-section valve opening department in order to block up small cross-section valve opening.
5. The concentrated water which does the rotary motion has the scouring function on the valve seat 20, and further, the enrichment and scaling of impurities in the valve seat 20 can be effectively prevented.
6. The concentrated water which does the rotary motion has mutual friction action between the concentrated water and the liquid inlet cavity 24, so that the concentrated water can be heated to a certain degree, and the concentrated water is heated in a low-temperature environment, which is beneficial to improving the water production efficiency.
In some preferred embodiments, valve housing 21 is formed with an annular recess 211 formed in the outer periphery thereof, the annular recess 211 having an axial position opposite to the axial position of fluid inlet 11 such that concentrate passes through fluid inlet 11 and first enters annular recess 211; the tangential inlets 25 comprise a plurality of tangential inlets 25 which are circumferentially arranged, and the concentrated water entering the annular groove 211 simultaneously enters the liquid inlet cavity 24 through the tangential inlets 25 arranged at different circumferential positions, so that the smoothness of the flow of the concentrated water is improved.
