The outer end of bar is fixed with knob, is rotated by knob inner sleeve relative to valve wall.Shelves are provided with the outer face of knob
Position indicator, shift indicator are used to indicate the waste water hole that can discharge fluid.
Fig. 8 is the structural representation of the waste water ratio valve of the utility model fourth embodiment.As can be seen from Figure 8, this reality
Applying the waste water ratio valve of example includes valve body 21, and valve body 21 has inner chamber 211 and surrounds the valve wall 212 of inner chamber 211, the one of valve body 21
End is provided with water inlet 30, and the other end is provided with supporter 213.Waste water ratio valve 20 also includes the piston being arranged in inner chamber 211
214, piston 214 is connected by flexible member 215 with supporter 213.
In the present embodiment, on valve wall 212 from the end of water inlet 30 towards the end of supporter 213 be disposed with waste water hole and
Flushing hole 50.The quantity of the waste water hole of waste water ratio valve is at least 2, and at least two waste water hole is from inlet end towards supporter end
Interval arranges successively.In fig. 8, the quantity of waste water hole is 3, respectively the first waste water hole 41, the second waste water hole 42 and the 3rd
Waste water hole 43, the first waste water hole 41, the second waste water hole 42, the 3rd waste water hole 43 and flushing hole 50 are supported from the end of water inlet 30 direction
The end of part 213 is spaced successively to be arranged.It is easily understood that more waste water holes can also be arranged as required to.
Figure 8 illustrates supporter 213 is fixed on the medial surface of valve wall 212.Flexible member 215 is preferably spring, living
Plug 214 is connected by spring with supporter 213.In the present embodiment, under water state processed, piston 214 be located at flushing hole 50 and with
Between the 3rd adjacent waste water hole 43 of flushing hole 50.
Waste water ratio valve in the present embodiment is additionally included in the inner sleeve in inner chamber 211 between water inlet 30 and piston 214
Cylinder 60, be provided with the sealing gasket and water hole corresponding with each waste water hole on inner sleeve 60, by make inner sleeve 60 relative to
Valve wall 212 is rotated so that fluid is discharged by different waste water holes and corresponding water hole.In actual production, inner sleeve 60
Gap between the madial wall of valve wall 212 may be too small, can not meet the requirement of flow, it is preferable that can make inner sleeve 60
Into hollow structure, and the hole for passing water through is opened up on the wall of inner sleeve 60, to improve the flow velocity of water.In fig. 8
State, the second waste water hole 42 and the 3rd waste water hole 43 are blocked by the corresponding sealing gasket 431 of second sealing gasket 421 and the 3rd respectively,
Fluid is discharged by the first waste water hole 41 and with 41 corresponding water hole 412 of the first waste water hole, or passes through inner sleeve 60 and valve wall
Gap between 212 madial walls flows through the first waste water hole 41 and discharged.
In the present embodiment, along the exterior circumferential of inner sleeve 60 a variety of sealing gaskets and water hole can be set to combine, from
And the waste water hole that can select to block any one or two or all in waste water hole does not block, different waste water is realized
Than.
When needing to be rinsed reverse osmosis water purification units, can be improved by improving the rotating speed of booster pump in inner chamber
Fluid pressure so that Fluid pressure against the force of the spring promotes piston 214 to move to right to the right-hand member of flushing hole 50, as shown in figure 9, this
When, the fluid in inner chamber is discharged by corresponding waste water hole and flushing hole, flow increase, is realized pre-washing function, is worked as pre-washing function
After end, booster pump is back to normal water state rotating speed processed, and Fluid pressure reduces in inner chamber, and piston is in the presence of flexible member
Water position processed corresponding to being back to, i.e., between the waste water hole 43 of flushing hole 50 and the 3rd, form waste water ratio function.
Figure 8 illustrates one end towards piston 214 of inner sleeve 60 is provided through piston 214, flexible member 215
With the connecting rod 219 of supporter 213.The outer end of connecting rod 219 is fixed with knob 216, by knob 216 can inner sleeve it is relative
Rotated in valve wall 212.In the present embodiment, in order to prevent fluid from being leaked from the through part of connecting rod 219 and piston 214, it is preferable that
The cooperation of connecting rod 219 and piston 214 will be enough to prevent fluid from leaking.Here, connecting rod 219 carries for the movement of piston 214 simultaneously
For guide effect, prevent piston from leading to not move due to unbalance stress.
, can be in knob 216 in order to which position and waste water ratio of the inner sleeve 60 relative to valve wall 212 can be observed at any time
At outer face or other positions set shift indicator, and the waste water hole that can discharge fluid is indicated using shift indicator, from
And conveniently understand current waste water ratio.For example, gear can be set to identify on the end face of knob, close to the end face of knob
Pointer, gear mark and pointer composition shift indicator are set on the end face of valve wall.By turn knob, make inner sleeve 60 relative
Rotated in valve wall so that pointer and corresponding gear mark are corresponding, so as to reach default waste water ratio, meanwhile, by observation and
The corresponding gear mark of pointer, can conveniently know current waste water ratio.
In the present embodiment, fast-connecting type plug is installed at water inlet 30 so that waste water ratio valve by fast-connecting type plug with
Counter-infiltration filter core 10 pipeline connection, the user of fast-connecting type plug dismounting, maintenance.
