First mouth of a river and second mouth of a river excessively excessively is sector.
The 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 surge pipe 20, the pressure regulation needle 23 closed at connecting pipe 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, surge pipe 20 is closed when in use, opens connecting pipe 19 pressure regulation needle 23
Reach adjusting rod 6 in maximum, regulation and reach certain flow value, then when occur in the water inlet 4 and valve pocket of valve pressure difference when
Wait, can be adjusted by Self-operated flow control assembly, be specially that current pass through pilot when water inlet pressure increases
Pipe 19 is entered at bottom flange 3, in the inner chamber for entering bottom flange 3, so that from ejection diaphragm 18 at the opening of upper spring bracket 24
Lug boss, so that diaphragm 18 is moved up, so as to drive the motion upwards of lower dolly bar 14, diaphragm 18 is with when motion
Film pad 26 is moved therewith, is moved to stopping movement when at lower outlet 16 and is played spacing effect, and lower dolly bar 14 is transported upwards
When dynamic lower spring bracket 25 can be driven to move simultaneously, the spring 17 so descended between spring bracket 25 and upper spring bracket 24 can produce compression,
Upper flap 12 and lower Disc 13 turn the size of upper water-out mouthful 15 and lower outlet 16 down, and such water amount just diminishes, Bu Huiyou
Become big in the pressure of water inlet 4 and increase flow, reach the purpose of constant flow rate, if instead the pressure of water inlet 4 reduces, diaphragm
18 rebound 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, now lower film pad 27, which moves downward to touch spring bracket 25 and play a part of lower limit, moves stopping.Therewith
Spring 17 unlike preceding herein does not play a part of directly conducting, but spring bracket 25 is anti-under the drive of lower dolly bar 14
To compression spring 17, spring 17 is only served an effect for providing reverse reset force, compared to pre-structure it is simpler, use
Life-span is longer.
On self-operated type pressure difference control assembly, in use, opening the hand-operated valve 22 on surge pipe 20, closing pressure-regulating valve pin
23, the upper turn of adjusting rod 6 to fully open position, the other end connection feed pipe of surge pipe 20, this valve is arranged on return pipe,
Current are entered by surge pipe 20 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 connecting pipe 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, but the lower spring bracket reverse compression spring under the drive of lower dolly bar, spring is only served one and carry
For the effect of reverse reset force, compared to pre-structure it is simpler, service life is longer, and connecting pipe uses the shape of external
Formula, different from internal-hole type before, use more facilitates.
