Description of the drawings
Fig. 1 is the schematic diagram of the gravity flow pressure regulation difference water supply system of the present invention.
Specific embodiment
The specific embodiment of the present invention is further illustrated below in conjunction with accompanying drawing.
As shown in figure 1, the poor confession of the gravity flow pressure regulation in two ponds and a set of fluid pressure type flat board weir composition utilized by the present invention
Water system, including：Head-tank (1), head-tank overflow well (2), low pool (3), low pool overflow well (4), a high position
Pool skimming weir (5), low pool flat board weir (6), head-tank far transmission level meter (7), remote control liquid flowmeter (8), teletransmission pressure reduction
Meter (9), low pool far transmission level meter (10), hydraulic opening-closing device (11), supply channel (12).
As seen from Figure 1, head-tank (1) provided by the present invention is provided with pond water inlet, Overflow drainage mouth, goes out
The mouth of a river (respectively such as node N01, N02, N03), the water inlet in pond, water outlet are floods stream.Head-tank (1) water level is maintained at
On head-tank downflow weir (5), unnecessary water Jing head-tank downflow weir overhead stream goes out, in head-tank overflow well (2),
Head-tank is discharged by node N02.The rational height of head-tank (1) at least ensures low pool (3) in high water level (i.e.
In low pool overflow well, low pool flat board weir (6) rests on pond highest order), meet being set with water on supply channel (12)
Standby minimum differential pressure requirements.A plurality of training wall is provided with head-tank (1), current are guided by training wall into the water in pond
Smooth flow, it is ensured that the water surface around at pond outlet N03 is stable.
As shown in figure 1, remote control liquid flowmeter (8) on supply channel (12) provided by the present invention, at node N04, is provided with, its
Function is the flow that supply channel is supplied to water equipment under each operating mode of measurement.In water equipment intake-outlet node N05, N06
Place picks out teletransmission differential manometer (9), and the differential pressure requirements needed under each operating mode of water equipment, by the low level in low pool overflow well
Pond flat board weir (6) matches operation to be automatically obtained with the teletransmission differential manometer (9) on supply channel.The nominal diameter of supply channel
Flow when highest pressure reduction supplies water as needed for water equipment is designing.
As shown in figure 1, low pool (3) provided by the present invention are provided with water inlet, Overflow drainage mouth (respectively such as node
N07, N08), for flooding stream, overflow discharge is gravity stream for the water inlet in pond.Dividing wall is provided with low pool (3), low
A low pool overflow well (4) is isolated in position pond (3).The rational height of dividing wall, need to ensure the low level in overflow well
When pond flat board weir (6) is adjusted to overflow well shaft bottom, dividing wall top is risen out on low pool flat board weir (6).Low pool (3)
The requirement that depth should meet water equipment highest pressure reduction operating mode is set.
As seen from Figure 1, low pool flat board weir (6) provided by the present invention are provided using hydraulic opening-closing device (11)
Power automatically adjusted in low pool overflow well (4) up and down.Under the different operating mode of water equipment, in low pool (3)
Different water levels (such as h1, h2, h3, h4 etc.) are corresponded to.The regulation height on low pool flat board weir (6) is different according to water equipment
The pressure difference of working condition requirement is being automatically obtained.For example, when water equipment is needed in 1 time operation of operating mode, corresponding water equipment
Inlet outlet pressure differential value be △ h, low pool flat board weir (6) according to programmed instruction come automatic controlled height, when on supply channel
When the pressure difference that teletransmission differential manometer (9) shows is consistent with the pressure reduction △ h of the working condition requirement, low pool flat board weir (6) is in program
Specify lower stopping to adjust, and the stable remote control liquid flowmeter (8) on the water level, supply channel (12) shows what is supplied under the operating mode
Flow, now thinks that flat board regulating weir is adjusted in place under this operating mode, in normal operating condition.Same operation principle, when
When water equipment needs another operating mode to run, the height of low pool flat board weir (6) is adjusted by programmed instruction.When with water
During equipment dynamic debugging, need from a certain operating mode, when varying continuously to next operating mode, low pool is adjusted by programmed instruction and is put down
Plate weir (6) height, so that reach the purpose of variable working condition dynamic debugging.
The illustration simply to the present invention of above-mentioned embodiment, the present invention can also with other ad hoc fashions or other
Particular form implement, without departing from idea of the invention or substitutive characteristics.Therefore, the embodiment of description comes in terms of any
See be regarded as it is illustrative rather than determinate.The scope of the present invention should be illustrated by appended claims, any to want with right
The equivalent change of the intention and scope asked also should be within the scope of the present invention.
