Power area 650 is different from the pressure in second pressure area 660, and the pressure in second pressure area 660 adds equal to the pressure in first pressure area 650
The elastic force of upper second spring 670, when when second pressure area, 660 pressure becomes larger, diaphragm 622 drives lower Disc 610 to move downward, the
Two springs 670 push, and elastic force increases at this time, reaches equilibrium state.When the change of 660 pressure of second pressure area is small, second spring 670
Release elastic force pushes out second spring seat 623, is further driven to lower Disc 610 and moves upwards, and elastic force reduces at this time, reaches flat
Weighing apparatus state.
Preferably, lower Disc 610 is set with 700 matched one end of current limliting sleeve for inverted cone shape, with the current limliting sleeve
The annular projection that 700 inner wall weeks set up is engaged；The maximum gauge of 610 taper of lower Disc is more than the current limliting sleeve
The diameter for the annular projection that 700 inner wall weeks set up.
Set specifically, lower Disc 610 is taper, be engaged with current limliting sleeve 700 be gradually turned on and off when, can be with
In linear regulation fluid flow.Avoid pressure jump caused by flow mutation.
Preferably, self-checking device 600 further includes：First pilot passage 630 and the second pilot passage 640；First
Pilot passage 630 includes：The axial hole axially set of the lower Disc 610 and 610 bottom of the lower Disc are radially set
Radial hole, the axial hole is connected with the radial hole, and is connected with first pressure area 650；Second pilot passage 640 is worn
Valve body 100 and bottom flange 300 are crossed, for connecting the outlet of valve body 100 and second pressure area 660.
Specifically, the first pilot passage 630 is used to be used for 650 conducting pressure of first pressure area, the second pilot passage 640
To 660 conducting pressure of second pressure area.It is different by the pressure in first pressure area 650 and second pressure area 660, further
Adjust the opening of lower Disc 610 and current limliting sleeve 700.
Please refer to Fig.1 and Figure 12, Fig. 1 be the utility model embodiment provide a kind of dynamic equilibrium valve section view
Figure；Figure 12 is the fluid flowing path and each several part pressure schematic diagram for a kind of dynamic equilibrium valve that the utility model embodiment provides.
As carried shown in 1 and Figure 12, when in use, fluid exports embodiment provided by the utility model into valve body 100,
The opening that lower Disc 610 is formed with current limliting sleeve 700 is first passed around, into current limliting sleeve 700；Secondly pressing plate 532 is passed through
The opening formed with current limliting sleeve 700, into the outlet of valve.When fluid enter valve body 100 outlet, without lower Disc
610 formed with current limliting sleeve 700 opening when, the pressure being here formed as is P1；When fluid is by lower Disc 610 and current limliting set
700 openings that are formed of cylinder, during the opening formed 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 the opening that fluid is formed by pressing plate 532 with current limliting sleeve 700, into valve
During 100 water outlet of body, the pressure being here formed as is P3.Fluid in current limliting sleeve 700 is by the first pilot passage 630 by fluid
First pressure area 650 is imported, therefore the pressure in first pressure area 650 is all mutually P2 with the pressure formed in current limliting sleeve 700；
Fluid in valve export directs fluid into second pressure area 660, therefore second pressure area 660 by the second pilot passage 640
Pressure and valve export in the pressure that is formed be all mutually P3.When diaphragm 622 is in equilibrium state, first pressure area 650
Pressure be equal to the sum of the elastic force of pressure and second spring 670 in second pressure area 660.As the increase of valve export pressure, i.e. P1
Pressure increases, and the pressure increase of further P2, the pressure in first pressure area 650 is more than the pressure and second in second pressure area 660
The sum of elastic force of spring 670, 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 increase of second spring 670, and reach balance again, i.e., the pressure in first pressure area 650 is equal to second pressure area 660
The sum of 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 sum of the pressure in second pressure area 660 and the elastic force of second spring 670, to recover 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 drive lower Disc 610 to move upwards, and during upward movement, 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 the pressure in second pressure area 660 and the elastic force 670 of spring.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 becomes with the opening of current limliting sleeve 700
It is small, therefore Kv diminishes, so Q is constant.When diaphragm 622 drives lower Disc 610 to move upwards,Reduce, because lower Disc
610 become larger with the opening of current limliting sleeve 700, therefore Kv becomes larger, so Q is constant.
When user needs voluntarily to adjust fluid flow and becomes larger, user is by controlling Electric Actuator to push down on moving axis
Core 520, shaft core 520 overcome the elastic force of the first spring 542 to drive upper flap 531 and pressing plate 532 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 upper flap 531 and pressing plate 532 is pasted completely with current limliting sleeve 700
Close, and then complete to close the function of valve.When user needs adjusting fluid flow to become small, user is by controlling electronic hold
Row device moves upwards, and shaft core 520 is moved upwards under the action of 542 elastic force of the first spring, and user can be according to different need
Ask and upper flap 531 and pressing plate 532 are rested on into different positions, pass through upper flap 531 and pressing plate 532 and 700 shape of current limliting sleeve
Into opening realize the linear regulation of flow.
