Background technique
With the rapid development of social economy, the living standard of the people is also being continuously improved, Urban House especially multilayer
More and more with high residential building quantity, secondary water-supply facility is also continuously increased, however secondary water-supply water quality management at present is not
Keep up with the paces of urban development.Water supply industry, which gradually measures summary table, passes through transformation by the secondary water-supply facility of estate management
Etc. approach transfer water undertaking's unified management, and also there is cleaning in 1 year in each water undertaking twice even more to secondary water supply tank
Repeatedly several administrative provisions, but the water quality of the municipal network water supply outside cell may be constructed by the external world, Changes in weather or
The factors such as tubing material pollute water quality in water supply network and also usually occur there is a phenomenon where booster and water supply scheduling, therefore supply
Usually equal customer complaints quality problem can just know quality problem afterwards for water enterprise, but there has been the tap water of water quality in this part
Into water tank, thus water undertaking can only by the way that cell is cut off the water, Water in Water Tank emptying clean again to water quality it is qualified after lead to again
Water, even if intaking vavle of water tank can be closed in advance in the case that the outer city planting ductwork water quality of cell is not up to standard, but due to reality
The complexity of municipal network water supply, actual water quality impact range usually and it is expected that discrepancy it is very big.
To solve above-mentioned contradiction, water undertaking also takes various measures, such as adds water quality in secondary pressurized pump house and exist
Line detector, generally on-line pH value detector, chlorine residue instrument and transmissometer；Such as cut off the water in practical booster and repairs and may will affect
In the case where water quality, it is as often as possible ready work and emergency preplan, but it is very high to the management requirement of personnel in this way, and
The data of municipal network water supply must be very complete, and all related valves must be able to normally-open and close, and Chinese water supply is existing
Shape certainly will there are a certain distance with such exacting terms.
Summary of the invention

Specific embodiment
The utility model and its specific embodiment are described in further detail below with reference to example, but the utility model
It is not limited to listed embodiment.
Fig. 1 is the layout drawing of the utility model.
Embodiment 1:
The utility model be applied to secondary water supply tank influent quality control system, including water inlet pipe (1), valve (2),
Water quality on-line detector (3), sewage pipe (4), blowdown motor-driven valve (5), filter (6), water tank water intake motor-driven valve (7), waterpower are distant
Control ball-cock assembly (8), water tank (9), PLC controller (10).Valve (2), water quality on-line detector (3), sewage pipe (4), filter
(6), water tank water intake motor-driven valve (7) and waterpower remote control float valve (8) are connected in turn on water inlet pipe (1), the water inlet pipe (1)
End and water tank (9) connection, the blowdown motor-driven valve (5) are arranged on sewage pipe (4), the output of water quality on-line detector (3)
End is connected with the input terminal of PLC controller (10), output end and blowdown motor-driven valve (4) and the water tank water intake electricity of PLC controller
Dynamic valve (7) connection.
A cell is high-rise (16,18 to the 20 layers) house in Building 17, and totally 1523 family, is all supplied using second pressure water supply mode
Water is all made of water tank+frequency conversion pressurization way of supplying water, and water tank total measurement (volume) is 200 tons, and water inlet pipe is steel pipe, and caliber is DN200 milli
Rice, sewage pipe are steel pipe, caliber is DN100 millimeter, are linked up according in secondary water-supply transformation process early period with infrastructure management company
Know that the cell periphery city planting ductwork time limit is longer, booster phenomenon often occur, it is super to will appear turbidity in short-term during repairing of cutting off the water
Phenomenon, therefore water quality on-line detector selection turbidity on-line detection instrument and chlorine residue on-line detector are marked, wherein turbidity on-line detection
Instrument setting value is upper limit value 0.6NTU, and it is 0.08mg/L that lower limit value, which is arranged, in chlorine residue on-line detector, and valve uses gate valve, filter
Using y-type filter.The cell secondary booster pump station was run over 3 years, because turbidity on-line detection instrument detects water tank water intake turbidity
More than upper limit value five times, and it is once two hours that the duration is longest, and reason is that repairing of cutting off the water due to booster causes, chlorine residue
On-line detector is not detected lower than lower limit value phenomenon, on the whole, is not influenced because water tank water intake water quality is unqualified
The normal water supply of user.
Embodiment 2:
The utility model be applied to secondary water supply tank influent quality control system, including water inlet pipe (1), valve (2),
Water quality on-line detector (3), sewage pipe (4), blowdown motor-driven valve (5), filter (6), water tank water intake motor-driven valve (7), waterpower are distant
Control ball-cock assembly (8), water tank (9), PLC controller (10).Valve (2), water quality on-line detector (3), sewage pipe (4), filter
(6), water tank water intake motor-driven valve (7) and waterpower remote control float valve (8) are connected in turn on water inlet pipe (1), the water inlet pipe (1)
End and water tank (9) connection, the blowdown motor-driven valve (5) are arranged on sewage pipe (4), the output of water quality on-line detector (3)
End is connected with the input terminal of PLC controller (10), output end and blowdown motor-driven valve (4) and the water tank water intake electricity of PLC controller
Dynamic valve (7) connection.
B cell is high-rise (14 to the 15 layers) house in Building 10, and totally 437 family, is all supplied water using second pressure water supply mode,
Using water tank+frequency conversion pressurization way of supplying water, water tank total measurement (volume) is 100 tons, and water inlet pipe is steel pipe, and caliber is DN100 millimeters, row
Dirt pipe is steel pipe, and caliber is DN50 millimeters, which is newly-built community, is located at area newly developed, it is contemplated that delivery is a few days ago moved in
Rate is lower, and the residence time that may have water in the newly-built ductile iron pipe in periphery too long causes pH value over-standard phenomenon, therefore water
Matter on-line detector selects pH value on-line detector, turbidity on-line detection instrument and chlorine residue on-line detector, and wherein pH value is examined online
Surveying instrument setting interval value is 6.5-8.0, and turbidity on-line detection instrument setting value is upper limit value 0.6NTU, the setting of chlorine residue on-line detector
Lower limit value is 0.08mg/L, and valve uses gate valve, and filter uses y-type filter.The cell secondary booster pump station is run 2 years
Come, is higher 12 times because pH on-line detector detects that water tank water intake pH value is located at outside setting section, duration longest
Be once half an hour, reason is that the residence time of water in peripheral ductile iron pipe is too long, turbidity on-line detection instrument and chlorine residue
On-line detector does not detect that setting limit value phenomenon is not influenced because water tank water intake water quality is unqualified on the whole
The normal water supply of user.
