Below introduce characteristics of the present invention and advantage in detail by specific embodiments of the invention and accompanying drawing.
Embodiment one:
As shown in Figure 1, present embodiment is to be provided with a Water-supplying tee joint pipe 4 at municipal water sources water inlet place, this Water-supplying tee joint pipe 4 can connect user's sanitary water end 5 respectively and the user drinks water end (W.E.) 7, wherein the user drinks water end (W.E.) 7 and is provided with screening system 6 with one of Water-supplying tee joint pipe 4 branch line, this screening system 6 is the drinking water screening system, can carry out filtration treatment to municipal water sources, make the water of final inflow user side capable of direct drinking, constitute the user and drink water end (W.E.) 7.In going between aquaporin and its wastewater outlet of described screening system 6, be provided with the return of waste water pipeline of a bypass, link to each other with the aquaporin of going into of screening system 6 by a backflow three-way pipe 2, a flow compensation valve 8 also is housed on the return of waste water pipeline, but the pressure of bucking-out system, be not subjected to the system pressure fluctuation when making return of waste water go into system and flowed fluctuation takes place, to guarantee the stable constant waste water ratio of water resistance and system of pipeline.
On the entry pipeline of screening system 6, also be provided with a pressure limiting valve 1, this pressure limiting valve 1 is positioned on the water source entry pipeline, on the pipeline between screening system 6 and the pressure limiting valve 1, be provided with a backflow three-way pipe 2, return of waste water pipeline and backflow three-way pipe 2 join, and the voltage limiting value of described pressure limiting valve 1 should be lower than in the screening system 6 force value of water on the wastewater produced inflow return of waste water pipeline, waste water can flow back in the water treatment system like this, reaches the waste water recycling purpose.
Because present municipal water quality much adopts the secondary water-supply form, simultaneously owing on the pipeline, make final inflow user's the corresponding reduction of water quality, simultaneously, because return of waste water is after system, the concentration of waste water will constantly raise.Therefore, on the entry pipeline of described screening system 6, also be provided with a water receptacle 3, it is positioned on user's sanitary water end 5 front end entry pipelines, and water receptacle 3 water sides are connected Water-supplying tee joint pipe 4 and backflow three-way pipe 2 respectively with water intake end.Be filled with elementary filtrate in the described water receptacle 3, become elementary drainage container.Elementary drainage container has three effects, and one after municipal water sources water tentatively can being filtered, uses as general sanitary water; Its two, do preliminary treatment for the water of screening system 6, can be follow-up drinking water and filter better condition is provided; Its three, the waste strength that flows into pipeline is changed slow down that (if 20 liters of the volumes of elementary drainage container 3 are made 4 liters of water purification at every turn, if the unmanned user's health water end (W.E.) 5 that uses during this, then the impurity of water rises 20% from 20 liters of 24 liters of simmer down tos in the system; If 4 liters of the volumes of elementary drainage container are made 4 liters of water purification at every turn, if the unmanned health water end (W.E.) 5 that uses during this, then the impurity of water rises 100%, so elementary drainage vessel volume is the bigger the better from 4 liters of 8 liters of simmer down tos in the system).
In the present embodiment, drinking water screening system 6 is counter-infiltration (RO) screening system, and the elementary filtrate of filling in the water receptacle 3 is selected milipore filter for use.
As shown in Figure 3, the present embodiment flow compensation valve comprises valve body 81, described valve body 81 offers inner chamber, offer the water inlet 82 that can be communicated with on the valve body 81 with this inner chamber, delivery port 83, in described body cavity, offer link to each other with water inlet 82 go into aquaporin 821, be provided with a flexible sheet 84 in the described inner chamber, its periphery be fixed on valve body 81 inner chambers set on the diaphragm pressure ring 841, inner chamber is isolated into upper chamber 811 and lower chambers 812, described to go into aquaporin 821 be an elongated straight through hole, water inlet 82, go into aquaporin 821, delivery port 83 all places valve body 1 epicoele.In the described upper chamber 811, be provided with a taper control lever 86, its upper end places in the aquaporin 821, the conical surface tapering off property from bottom to top is progressive, length extends in the aquaporin 821, and goes into the gap formation waste water tunnel between the aquaporin 821, and the lower end is positioned at flexible sheet 84 tops.Be arranged with spring 861 on the described control lever 86, these spring 861 1 ends are fixed on the valve body 81, another termination control lever 86 bottoms.Water is after water system 6 purifies after filtration, and waste water will flow back into screening system 6 entry pipelines by delivery port 83 by backflow three-way pipe 2 again by water inlet 82 in waste water tunnel flows into upper chamber 811, filter once more.Because return of waste water is to carry out in a closed-loop system, the delivery port 83 of flow compensation valve 8 has certain pressure, therefore, flow compensation valve 8 is arranged at water inlet 82 and delivery port 83 on the same cavity, because going into aquaporin 821 is an elongated straight through hole, control lever 86 has certain tapering, the control lever 86 of taper is in water inlet 82 when mobile, the gap that can make control lever 86 and go between the aquaporin 821 changes, and this variation increases and increases along with delivery port 83 pressure, and both are proportional.Like this, can change waste water entry aisle spare, regulate the resistance of water, thereby can control the flow that waste water enters flow compensation valve 8, keep the stable of flow by moving of control lever 86.
The operation principle of flow compensation valve 8 is as follows:
When the pressure of flow compensation valve 8 delivery ports 83 equaled to set value, the elastic force of flexible sheet 84 self and the hydraulic pressure of upper chamber 811 kept balance, the hydraulic pressure maintenance balance that the elastic force of spring 861 and control lever 86 bear, and flexible sheet 84 and control lever 86 do not have displacement.
The pressure of water on the return of waste water pipeline when just the hydraulic pressure of flow compensation valve 8 delivery ports 83 increases, will cause the fluid pressure of valve body upper chamber 811 to increase, and the water resistance at water inlet 82 places also will increase, and flow will reduce.But this moment, the fluid pressure of valve body upper chamber 811 will promote flexible sheet 84 and move downward, the space of upper chamber 811 is increased, hydraulic pressure acts on the control lever 86 simultaneously, promoting its resistance that overcomes control lever spring 861 moves downward, because control lever 86 is a cone-shaped component, its outer surface and the slit of going between the aquaporin 821 increase in the process that moves downward gradually, the cross-sectional area that is waste water tunnel increases gradually, flow increases gradually, water resistance reduces, thus stoped the minimizing of wastewater flow, thus keep stable water resistance and the waste water ratio of return of waste water pipeline.
The pressure of water on the return of waste water pipeline when just the hydraulic pressure of flow compensation valve 8 delivery ports 83 reduces, causes the fluid pressure of valve body upper chamber 811 to decrease, and the water resistance of water inlet 82 will reduce, and wastewater flow will increase.But this moment, the elastic force of flexible sheet 84 self is greater than hydraulic pressure, move on the flexible sheet 84, the resistance that push lever 86 overcomes spring 861 moves up, and moves past in the journey on control lever 86, dwindle gradually with the slit of going into aquaporin 821, the cross-sectional area that is runner reduces, and waste water flow gradually reduces, and water resistance increases, so stoped the increase of wastewater flow, thereby kept stable water resistance and the waste water ratio of return of waste water pipeline.
Embodiment two:
As shown in Figure 2, present embodiment two is on the basis of embodiment one, also there is discharge of wastewater valve 10 in branch on the return of waste water pipeline between screening system 6 and the flow compensation valve 8, it specifically is to be provided with blowdown three-way pipe 9 on the pipeline that is communicated with between flow compensation valve 8 and the discharge of wastewater valve 10, discharge of wastewater valve 10 joins with blowdown three-way pipe 9, and discharge of wastewater valve 10 is selected the high-concentration wastewater emission magnetic valve for use.If the user does not use user's sanitary water system 5 for a long time, then the waste strength in the system can be very high, and at this moment, the high-concentration wastewater emission magnetic valve can detect high-concentration waste water and self-control drainage, prevents blocking pipeline.
The flow compensation valve 8 that is adopted in the present embodiment can adopt another kind of version, the valve body 81 of present embodiment flow compensation valve 8 is identical with embodiment one as shown in Figure 4, control lever 86 also is a tapered rod, different is, the below of flexible sheet 84 is provided with supporting plate 85, the upper end of control lever 86 places aquaporin 821, and itself and the slit of going between the aquaporin 821 are tapering, and it is affixed with supporting plate 85 that flexible sheet 84 is passed through in the lower end.Along with control lever 86 moving up and down in going into aquaporin 821, itself and the slit of going between the aquaporin 821 also change thereupon, thereby regulate water resistance and flow.
The operation principle of present embodiment flow compensation valve 8 is as follows:
The pressure of water on the return of waste water pipeline, when promptly the pressure of flow compensation valve 8 delivery ports 83 equaled to set value, the elastic force of flexible sheet 84 self and the hydraulic pressure of upper chamber 811 kept balance, and flexible sheet 84 and control lever 86 do not have displacement.
When the pressure of water on the return of waste water pipeline, i.e. the pressure increase of flow compensation valve 8 delivery ports 83 cause the fluid pressure of valve body upper chamber 811 to increase, the water resistance at water inlet 82 places also will increase, and flow will reduce.But this moment, the fluid pressure of valve body upper chamber 811 will promote flexible sheet 84 and move downward, the space of upper chamber 811 increases, pressure reduces, stoped the increase of water inlet 82 water resistances, simultaneously, moving down of flexible sheet 84, to promote supporting plate 85 and move down, and then drive control lever 86 and move downward control lever 86 upper ends and the slit increase of going between the aquaporin 821, the cross-sectional area that is the water inlet runner increases, flow increases, and has stoped the minimizing of wastewater flow, thereby keeps stable water resistance and the waste water ratio of return of waste water pipeline.
The pressure of water on the return of waste water pipeline, when promptly the hydraulic pressure of flow compensation valve 8 delivery ports 83 reduced, the fluid pressure of valve body upper chamber 811 decreased, and the water resistance of water inlet 82 will reduce, and wastewater flow will increase.But this moment, the elastic force of flexible sheet 84 self will be greater than hydraulic pressure, moves on the flexible sheet 84, and the resistance that push lever 86 overcomes spring 861 moves up.Reduce in the space of upper chamber 811 on the one hand, and pressure increases, and has stoped the minimizing of water inlet 82 water resistances; Move the slit that makes it and go into aquaporin 821 on the while control lever 86 and dwindle, promptly the cross-sectional area of runner reduces, and wastewater flow reduces, and has stoped the increase of wastewater flow, thereby keeps stable water resistance and the waste water ratio of return of waste water pipeline.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
