Connection.
Upper flow regulating plate 8 and down-off adjustment sheet 9 are made of stainless steel.
First mouth of a river and second mouth of a river excessively excessively is sector.
Upper flap 12 and lower Disc 13 are copper material.
For upper flow regulating plate 8 to be circular, second on the upper flow regulating plate 8 crosses the mouth of a river as symmetrically arranged two,
Described second, which crosses the mouth of a river, extends along the change rate of direction openings of sizes and becomes larger, and described first crosses the mouth of a river crosses the mouth of a river with second
Shape it is identical.
Below to being described using process：Primarily with respect to digital locked balance valve component, balanced using number lock
When valve module, the needle-valve 20 on external connecting pipe 19 is closed, the hand-operated valve 30 on surge pipe 23 is closed, is also switched off pressure release
Ball valve 22 on pipe 21, only adjusts upper exposed junction of the adjusting rod 6 at bonnet, 2, and the mouth of a river is crossed to adjust first by its rotation
And second cross the mouth of a river between registration, to change flow, rotate while on adjusting rod 6 digital display piece 7 can be driven to show not
Same KV values, can be converted into flow value, the valve possesses the function of digital locked balance valve at this time.
On Self-operated flow control assembly, the hand-operated valve 30 on surge pipe 23, the ball being also switched off on relief tube 21 are closed
Valve 22, opens the needle-valve 20 on external connecting pipe 19 and reaches maximum, adjusting rod 6 reaches certain flow value in adjusting, then
When there is pressure difference in the water inlet 4 and valve chamber of valve, it can be adjusted by Self-operated flow control assembly, specifically
For when pressure increases at water inlet 4, current are entered at bottom flange 3 by external connecting pipe 19, enter bottom flange 3
In inner cavity, so that the lug boss of the opening ejection diaphragm 18 from upper spring bracket 24, so that diaphragm 18 moves up, so as to drive
Lower dolly bar 14 moves upwards, and lower dolly bar 14 moves upwards when can drive lower spring bracket 25 to move at the same time, so descend spring
Spring 17 between support 25 and upper spring bracket 24 can produce compression, upper flap 12 and lower Disc 13 by upper water-out mouth 15 and lower outlet
16 size is turned down, and such water amount just diminishes, and will not be become larger due to 4 pressure of water inlet and be increased flow, reach steady flow
The purpose of amount, if instead 4 pressure of water inlet reduces, diaphragm 18 rebounds under the action of spring 17, so as to increase upper water-out mouth
15 and the size of lower outlet 16, increase water amount, equally make flow constant, lower film pad 27, which moves downward, at this time touches
Spring bracket 25, which plays the role of lower limit, moves stopping.From before unlike spring 17 herein do not play what is directly conducted
Effect, but the 25 reverse compression spring 17 of spring bracket under the drive of lower dolly bar 14, make spring 17 only serve one and provide reversely
The effect of reset force, compared to pre-structure it is simpler, service life is longer.
On self-operated type pressure difference control assembly, in use, opening the hand-operated valve 30 on surge pipe 23, close on relief tube 21
Ball valve 22, the ball valve 22 being also switched off on relief tube 21, upper 6 turn of adjusting rod to fully open position, 23 openend of surge pipe connects
Feed pipe is connect, this valve is arranged on return pipe, and current are entered by surge pipe 23 in the inner cavity of bottom flange 3, and then ejection
Diaphragm 18, makes lower Disc work automatically, keeps the pressure difference of controlled system constant, plays the role of Differential Pressure Controller.
Manually valve 30, adjust the size of 23 aperture of surge pipe, adjust the magnitude of pressure differential of controlled system.
It is illustrated in figure 3 the structure diagram of flow regulating plate, the structure of down-off adjustment sheet 9 and upper flow regulating plate
8 structure is the same, both align up and down, by the opening shape in figure on upper flow regulating plate 8 it is known that when being rotated from
Rise, rotate same angle, the size that two adjustment sheet upper sheds align is increasing, i.e., change rate is increasing, so sets
It is requirement in order to meet flow component and pressure difference component to put, and pressure difference is excessive sometimes, can not be protected if opening very little is aligned
It is constant to demonstrate,prove flow, so pivoted eyelid again, increase opening change rate, then can meet that flow is constant, so meet to flow at the same time
Amount balance and pressure balance.
Effect possessed by the utility model is, the valve except with repertoire possessed by Multifunctional balance valve it
Outside, most important inventive point is different from internal-hole type before, and the pressure guide hole of flow control assembly is arranged to external shape
Formula, it is more convenient to use easy to overall control and maintenance.
