Fig. 1 and Figure 12 is please referred to, Fig. 1 is a kind of cross-sectional view of dynamic equilibrium valve provided in an embodiment of the present invention；Figure
12 be a kind of fluid flowing path and each section pressure schematic diagram of dynamic equilibrium valve provided in an embodiment of the present invention.
As mentioned shown in 1 and Figure 12, when in use, fluid enters the outlet of valve body 100 to embodiment provided by the invention, first
It is formed by opening by lower Disc 610 and current limliting sleeve 700, into current limliting sleeve 700；Secondly by pressing plate 532 and limit
Stream sleeve 700 is formed by opening, into the outlet of valve.When fluid enters the outlet of valve body 100, without lower Disc 610
When being formed by opening with current limliting sleeve 700, the pressure being here formed as is P1；When fluid is by lower Disc 610 and current limliting sleeve
700 are formed by opening, when being formed by opening without pressing plate 532 and current limliting sleeve 700, i.e., when fluid is in current limliting sleeve
When in 700, the pressure being here formed as is P2；When fluid is formed by opening by pressing plate 532 and current limliting sleeve 700, into valve
When 100 water outlet of body, the pressure being here formed as is P3.Fluid in current limliting sleeve 700 passes through the first pilot channel 630 for fluid
First pressure area 650 is imported, therefore being formed by pressure in the pressure in first pressure area 650 and current limliting sleeve 700 is mutually all P2；
Fluid in valve export directs fluid into second pressure area 660, therefore second pressure area 660 by the second pilot channel 640
Pressure and valve export in be formed by pressure be mutually all P3.When diaphragm 622 is in equilibrium state, first pressure area 650
Pressure be equal to second pressure area 660 pressure and second spring 670 the sum of elastic force.As the increase of valve export pressure, i.e. P1
Pressure increases, and the pressure of further P2 increases, and the pressure in first pressure area 650 is greater than the pressure and second in second pressure area 660
The sum of the elastic force of spring 670, will restore balance, it is necessary to increase the pressure in second pressure area 660 and the bullet of second spring 670
Power, for diaphragm 622 due to force unbalance, diaphragm 622 drives lower Disc 610 to move downward at this time, during moving downward,
The elastic force of second spring 670 increases, and reaches balance again, i.e., the pressure in first pressure area 650 is equal to second pressure area 660
The sum of the elastic force of pressure and second spring 670.When valve export pressure reduces, i.e., P1 pressure reduces, and the pressure of further P2 subtracts
Small, the pressure in first pressure area 650 is less than the pressure in second pressure area 660 and the sum of the elastic force of second spring 670, to restore flat
Weighing apparatus, it is necessary to reduce the pressure in second pressure area 660 and the elastic force of second spring 670, diaphragm 622 is due to stress injustice at this time
Weighing apparatus, diaphragm 622 drives lower Disc 610 to move upwards, and during moving upwards, the elastic force of second spring 670 reduces, and again
Secondary to reach balance, i.e. the pressure in first pressure area 650 is equal to the sum of pressure and the elastic force 670 of spring in second pressure area 660.Root
According to flow formulaWherein Q is the flow by valve, and Kv is discharge coefficient, and Δ P is pressure difference, Δ P=P1-
P2, when diaphragm 622 drives lower Disc 610 to move downward,Increase, because lower Disc 610 and the opening of current limliting sleeve 700 become
It is small, therefore Kv becomes smaller, so Q is constant.When diaphragm 622 drives lower Disc 610 to move upwards,Reduce, because of lower Disc
610 become larger with the opening of current limliting sleeve 700, therefore Kv becomes larger, so Q is constant.
When user, which needs voluntarily to adjust fluid flow, to become larger, user pushes down on moving axis by controlling Electric Actuator
Core 520, central spindle 520 overcome the elastic force of the first spring 542 that upper flap 531 and pressing plate 532 is driven to move downward, and user can root
Upper flap 531 and pressing plate 532 are rested on into different positions according to different demands, pass through upper flap 531 and pressing plate 532 and current limliting
The opening that sleeve 700 is formed realizes the linear regulation of flow.When user needs to close valve, user is electronic by controlling
Actuator drives upper flap 531 and pressing plate 532 to move downward, and pastes upper flap 531 and pressing plate 532 and current limliting sleeve 700 completely
It closes, and then completes to close the function of valve.When user, which needs to adjust fluid flow, to become smaller, user is by controlling electronic hold
Row device moves upwards, and central spindle 520 moves upwards under the action of the first 542 elastic force of spring, and user can be according to different need
It asks and upper flap 531 and pressing plate 532 is rested on into different positions, pass through upper flap 531 and pressing plate 532 and 700 shape of current limliting sleeve
At opening realize flow linear regulation.
When user needs preset valves flow, user's rotary manual regulating device 400 passes through manual regulating device
Digital 1-6 on 400 top surfaces is aligned with the identification hole on 200 top surface of bonnet, to select different preset flow ranges, is realized
Second throttle orifice 410 of manual regulating device 400 is matched with the first throttle orifice 210 of bonnet, 200, further reaches pre-
First set the purpose of 100 flow of valve body.
The present invention is by setting electric adjusting device, manual regulating device, self-checking device and current limliting sleeve to valve
Pipeline belonging to door carries out flow adjusting.Manual regulating device against the setting of one end of valve body there are six the second throttle orifice, six the
The size of two throttle orifices is incremented by successively, and by the mating reaction with bonnet, can preset the flow of pipeline, prevent
The loss of fluid.On the basis of preset piping flow, then pass through self-checking device and current limliting sleeve one end fits
It automatically adjusts, further further accurate by electric adjusting device and the cooperation progress of the current limliting sleeve other end
Control, can reach flow and be fine-tuned in a small range, reach the high-precision precise controlling of flow.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
