Description
Technical field
The ductwork pressure tune realized the present invention relates to the portable system of public supply mains pressure controlling and using the system
Prosecutor method, belongs to water supply network pressure controlling research field.
Background technology
With the fast development and the continuous reduction of water resource of social economy, water supply industry to the water application efficiency of pipe network all the more
Concern.Because China's water supply network aging is serious, tubing is inferior, the problems such as damage is run, and causes pipe network model serious,
Subregion pressure is not (being difficult to meet minimum service head) up to standard, and water application efficiency is low.Because pressure with flow (wastage) is in
Positive relation, pressure is higher, and wastage is bigger.Therefore while regional water supply user's pressure demand is met, reasonable adjusting pipe
Net pressure, makes pipe network work under reasonable pressure, can extend pipe network life-span and reduction pipe network leak rate, reduce booster, water hammer
Etc. accident.Regulation ductwork pressure mainly meets water undertaking's reduction leakage and regional water supply by depressurizing or being pressurized two ways
User's pressure demand.
Reduction water supply network pressure more than needed can be carried out by way of adjusting the valve opening in pipe network, but long-term by half
Valve opening door, can influence life of valve.Compared to common valve, pressure-reducing valve is more common in Practical Project, and pressure-reducing valve can lead to
Inlet pressure is overregulated, optimal control ductwork pressure reaches the purpose of reduction pipe network leak rate.
Existing water supply network decompression control program is mainly that the equipment such as pressure-reducing valve are provided with installation pressure-reducing station, pressure-reducing station,
Pressure-reducing station can be according to the water demand of user, reasonable adjusting systematic Water supply pressure.Prevent water supply network big because of pressure change, and send out
The failures such as raw booster, water hammer, pipe network model.The arrangement form of pressure-reducing station is generally divided into two kinds above and below the ground, underground installation side
It is limited to there is operating space in formula, the problems such as maintenance difficult.Therefore, many arrangement sides of pressure-reducing station using ground in Practical Project
Formula.But installing pressure-reducing station on the ground, there is also defect：Space-consuming is excessive, there are problems that expropriation of land during installation, pressure-reducing station peace
It can not be moved after dress and pressure controlling strategy is single, cause unnecessary investment waste.
Because water supply network is long, and there are problems that, it is too low in the end hydraulic pressure of pipe network so that pipe network end region
The domestic water of domain user is affected, therefore increase ductwork pressure is particularly important in water-supply systems.Current feed pipe
The boosting rectifier control scheme of net is mainly installation pressurized pump station.But there is also defect for pressurized pump station：Fixed space is needed to be used to pacify
, so there is certain expropriation of land and can not be moved after installing, cause unnecessary investment waste in dress construction.

If the pressure data of least favorable point exceedes setup pressure value, decompression operation is carried out to the region pipe network entrance, step is performed
Five；
If the pressure data of least favorable point is less than minimum service head corresponding pressure, supercharging behaviour is carried out to the region pipe network entrance
Make, be then transferred to step 6；
Step 5: opening the Hand-operated butterfly valve (2) on relief line (10), the Hand-operated butterfly valve (2) closed on bypass pipe (11) passes through
The adjustment aperture of switch board (7) control C valves (1), is depressurized, and current is only passed through relief line (10)；
Step 6: opening the Hand-operated butterfly valve (2) on pressure piping (13), the Hand-operated butterfly valve (2) closed on bypass pipe (11) passes through
Switch board (7) controls booster pump (12) pressure, current is only passed through pressure piping (13).
