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.
Below to being described using process：Primarily with respect to digital locked balance valve component, balanced using number lock
When valve module, the hand-operated valve 22 closed on connecting pipe 21, the pressure regulation needle 23 closed at pressure guide hole 19 is only adjusted in regulation
Exposed junction of the bar 6 at bonnet, 2, first is adjusted by its rotation and crosses the mouth of a river and the second registration crossed between the mouth of a river, is come
Change flow, rotate while on adjusting rod 6 digital display piece 7 can be driven to show different traffic figures, can intuitively read
Traffic figure, now the valve possess the function of digital locked balance valve.
On Self-operated flow control assembly, connecting pipe 21 is closed when in use, pressure regulation needle 23 is reached maximum, adjust
Upper adjusting rod 6 reaches certain flow value, then when there is pressure difference in the water inlet 4 and valve pocket of valve, can be by certainly
Power formula flow control assembly is adjusted, and when being specially that pressure increases at water inlet 4, current are entered down by pressure guide hole 19
At bonnet 3, in the inner chamber for entering bottom flange 3, so that the lug boss of ejection diaphragm 18, so that diaphragm 18 is moved up, from
And the motion upwards of lower dolly bar 14 is driven, upper film pad 26, lower film pad 27 are moved therewith when diaphragm 18 is with motion, are moved to
Play spacing effect during lower outlet 16, and lower dolly bar 14 can make spring 17 to produce compression when move upwards, instead
Lower limit effect is played to coordinating when motion, between spring bracket 24 and upper water-out mouthful 15, upper flap 12 and lower Disc 13 will be upper
The size of delivery port 15 and lower outlet 16 is turned down, and such water amount just diminishes, and will not be become big due to the pressure of water inlet 4 and be made stream
Amount increase, reaches the purpose of constant flow rate, if instead the pressure of water inlet 4 reduces, diaphragm 18 rebounds in the presence of spring 17,
So as to increase the size of upper water-out mouthful 15 and lower outlet 16, increase water amount, equally make flow constant.From it is different before
It is that spring 17 herein does not play a part of directly conducting, but in the compression for realizing spring 17 of lower dolly bar 14, makes bullet
Spring 17 only serve one offer reset force effect, compared to pre-structure it is simpler, service life is longer, and spring bracket 24 is directly met
Water impact is connect, is unlikely to make it directly impact the damage that flap causes flap, flap is effectively protected, current can be from connection
Flow through in water space of crossing between pawl 25.
On self-operated type pressure difference control assembly, in use, opening the hand-operated valve 22 on connecting pipe 21, closing pressure-regulating valve pin
23, the upper turn of adjusting rod 6 to fully open position, the other end connection feed pipe of connecting pipe 21, this valve is arranged on return pipe,
Current are entered by connecting pipe 21 in the inner chamber of bottom flange 3, and then ejection diaphragm 18, lower Disc is worked automatically, are kept
The pressure difference of controlled system is constant, plays a part of Differential Pressure Controller.By pressure regulation needle 23, the aperture of pressure guide hole 19 is adjusted
Size, adjust controlled system magnitude of pressure differential.
The utility model had the effect that, the valve except the repertoire that has with Multifunctional balance valve it
Outside, topmost inventive point is the set location and setting form of spring, and the spring unlike before herein does not rise
To the effect directly conducted, spring is only served the effect of an offer reset force, compared to pre-structure it is simpler, use the longevity
Life is longer, and spring bracket is provided with the mouth of a river in upper cross, and spring bracket directly meets water impact, is unlikely to make it directly impact flap to make
Into the damage of flap, flap is effectively protected, current can flow through from the water space of crossing between connection pawl.
