Abstract
Timesharing district heating system belongs to central heating technical field.Several heating zones form.The heating equipment of each heating zone is made up of machine control valve 2, temperature sensor 3, section valve 4, radiator group 5.The heating equipment of each heating zone is controlled by master control cabinet 1.Each heating zone through water supply arm 7, then after elder generation after machine control valve 2, temperature sensor 3 to radiator group 5 heat radiation, then is returned backwater supervisor 9 through return branch 8 by vibration means for main pipe for supplying water 6.The machine control valve 3 of each heating zone also connects bypass line, upper truncation valve 4；For some reason when power failure or control system fault, a manually section valve 4 can be opened and heat.The heat supply of heating zone, interval chronologically or cooling lower limit controls；Or interval, cooling declines co-controlling chronologically.Each heating point of same heating zone can balanced heating；The change that heat is different is needed afterwards, round the clock in before adapting to heating period；Thermal power plant unit operates steadily；Compensate for can save energy again when the under-supply vacancy of total heat energy and total heat energy abundance.For central heating system.
Description
Technical field
Central heating.
Background technology
The day heat supply total amount of existing concentrated supply of heating in the city is by thermal design needed for locality the coldest period.Heating equipment exists
The coldest oepration at full load in period.But, in the stage at the whole story of heating period, weather does not reach the coldest.Then heating plant just load shedding fortune
OK.It is true that the temperature in any one place is all that to warm up night daytime cold, therefore heating equipment is always for for stopping rather than one day
Within 24 hours, running, this just makes to heat every time is all that whole heat supply pipeline is heated up, and causes heat waste.Equipment frequent start-stop also rapid wear
Bad.
Summary of the invention
Timesharing district heating system to solve the technical problem that: each heating point heat supply in turn of a heating zone.
The technical scheme is that timesharing district heating.
Timesharing district heating system (Fig. 1) is by several heating zone A, B, C, D ... composition.The heating equipment of each heating zone
Formed by machine control valve 2, temperature sensor 3, section valve 4, radiator group 5.The heating equipment of each heating zone is controlled by master control cabinet 1
System.Each heating zone by vibration means for main pipe for supplying water 6 through water supply arm 7, then first after through machine control valve 2, temperature sensor 3, to radiator
After group 5 heat radiation, then return backwater supervisor 9 through return branch 8.The machine control valve 2 of each heating zone also connects bypass line, upper truncation valve
4；For some reason when power failure or control system fault, a manually section valve 4 can be opened and heat.
Timesharing district heating system provides the benefit that: 1, each heating point in same heating zone can be kept away with balanced heating
Exempt from each heating point uneven in temperature.2, need heat to have after in adapting to before heating period to have less more, need heat to have round the clock to have few change more.3, keep away
Exempt from the frequent start-stop of thermal power plant unit, the most daily may operate at a rational loading, operate steadily.4, compensate for total heat energy
Can save energy again when under-supply vacancy and total heat energy abundance.
Accompanying drawing explanation
Fig. 1 shows timesharing district heating system schematic diagram.
In figure: 1 master control cabinet；2 machine control valves；3 temperature sensors；4 sections of valves；5 radiator groups；
6 vibration means for main pipe for supplying waters；7 water supply arms；8 return branch；9 backwater supervisors；A, B, C, D heat district.
Detailed description of the invention
Master control cabinet 1 is by the single-chip programming control time relay, temperature controller, digital display instrument.Anti-according to each heating zone temperature sensor 3
The data of feedback, implement timesharing district heating to each heating zone.
Machine control valve 2 uses electromagnetic valve or pneumatic operated valve.
Cut valve 4 and use hand-operated valve, in order to use during without electricity.
The heat supply of heating zone, by heat supply time ordered interval (some is to some) or cooling lower limit, (temperature sensor 3 is down to how many
Degree) control；Or by heat supply time ordered interval, cooling lower limit co-controlling.
