Embodiment
The present invention describes in detail below in conjunction with accompanying drawing:
See Fig. 1, the top heat supply main 1 that is provided with of the present invention's heating floor.The upstream and downstream of the common riser 13 that joins with heat supply main is respectively equipped with stop valve 32 and 33, for adjusting along the heat balance between each common riser on the main 1, is provided with equalizing valve 31 in the downstream of valve 32, enters the caloic flow of each heat supply main with adjustment.Be communicated with on the heat supply main 1 and backwater main 19 and unit users heat supply load between common riser 13, wherein common riser 13 is communicated with horizontal heating tube 20 and horizontal return pipe 21 with each user's heat supply load.The upstream that is positioned at top user at common riser 13 is provided with filtrator 2 and remote control liquid flowmeter 3, and filtrator 2 wherein is used to protect flowmeter 3, and flowmeter 3 then is to be used to detect the caloic flow that enters pipeline 13 sons.Downstream at flowmeter 3 is communicated with common riser 13 with horizontal heating tube 20 and horizontal return pipe, and at user's horizontal heating tube 20 and the standpipe part cross-over connection between horizontal return pipe the valve 4 of leap is arranged.As seen, because the influence of the system architecture that installation flowmeter and filtration unit etc. cause, leap valve top and bottom one deck is to be located in one section horizontal tube among Fig. 1, and remaining each layer user's leap valve 4 then directly is located on the common riser 13.On each horizontal heating tube 20 of standpipe 13 and the downstream that is connected to the contact of crossing over valve 4 shut-off valve 5 is installed, and each user's horizontal return pipe 21 and the upstream that is connected to the contact of crossing over valve 4 also are equipped with shut-off valve 22.For ease of the heat supply situation is carried out multiple detection, be equipped with inspection joint 6 and 11 in the downstream of shut-off valve 5 and the upstream and downstream of shut-off valve 22.Described shut-off valve 5,22 and inspection joint all are positioned at outside user's partition wall.Inspection joint 6 and 11 is used the plug shutoff when normal the use, only open when checking.Upstream at the horizontal heating tube 20 that is positioned at user's indoor section is provided with stop valve for three-way flow proportional distribution 8, and the bypass in valve 8 is communicated with stop valve for three-way flow proportional distribution with a bypass duct with horizontal return pipe 21, and the parallel-connection structure of formation and heating load circuit.Each user is with data acquisition controller 9 control stop valve for three-way flow proportional distribution, simultaneously by being located at the measured temperature signal of temperature sensor 10 on the heat supply pipeline section also by in the feed-in data acquisition controller 9.It is indoor that temperature sensor 10 among the present invention can be located at the user, and both as shown in Figure 1, it was outdoor also can be located at the user, as was arranged on the valve 5.The downstream of the contact of the leap valve 4 that is connect on undermost heating user's horizontal return pipe is provided with filtrator 25 and second remote control liquid flowmeter 18, and is provided with another temperature sensor 17.Respectively warm oneself the in the present invention measured temperature signal of flow signal, temperature sensor 17 of each remote control liquid flowmeter 3 and 18 resulting heating mediums in the unit, and the resulting signal of each user's data acquisition controller all is delivered to cell controller 15 places with polycore cable.The data that cell controller 15 is exported then are transferred in the computer system 12 by polycore cable 14, carry out corresponding calculated and processing, and relevant result of calculation is fed back to cell controller and user data acquisition controller.All heating loads along the user that respectively warms oneself of the same side height among the present invention provide caloic by same common riser 13, and this just provides the foundation by used heat metering and charge for the branch family.As seen, the part among the present invention outside user's partition wall can be a shared pipeline enclosure in Fig. 1 for other.
In service in reality, a certain user's (as the N+1 layer) heat is by measuring the flow of total system, measure the heating tube temperature of the user of one deck (as the N layer) below the temperature of this user's heating tube and this user, and the thermal mass flowmeter of getting measured two temperatures difference and total system is calculated the calorie value of this user's heat supply, calorie value is added up, this user's heat cost is collected in calorie value charging with accumulation, perhaps user's calorie value and the calorie value bought in advance of user with accumulation compares, when calorie value that user's heat history value is bought in advance less than the user, continue heat supply, when user's heat history value equals calorie value that the user buys in advance, stop to this user's heat supply.So can realize dividing the family by used heat metering and charge to central heating.
If measure its gained heat by the actual flow that enters user's heat supply load and this user's the horizontal heating tube and the temperature difference of horizontal return pipe, should be science the most, the present invention can adopt this mode to measure and charge too.But the employing of this method requires to install flow measurement device additional before each user's heat supply load, requires reload temperature sensor on each user's horizontal return pipe simultaneously, and this can cause the increase of total system cost; On the other hand, because heat waste also can take place in the caloic that directly flows out along common riser, and the complexity that will become the charging problem of this part heat.But adopt front of the present invention to recommend described method to measure and charge, each user's charge can be gone in the caloic loss stand of common riser part, example so relatively, and all can be greater than relevant criterion to the error that each user produced; On the other hand, adopt the method for recommending to carry out the quantity that meterage can also reduce the hardware of total system use greatly, reduce the cost of system.
In invention, can set up relevant operation program, adopt single-chip microcomputer to form user data acquisition control device and cell controller simultaneously, can realize the metering and the charge of total system are calculated according to above-mentioned method.And in the user data acquisition control device, adopt on the photoelectricity card or IC-card technology also to realize non-cash reimbursement of expense and monitoring.
Except that above-mentioned relevant advantage, the present invention can also carry out the inspection of heat supply correlation parameter very easily and carry out the adjustment of heat supply balance.
For example:
Whether accurate by insert standard thermometer in joint 6 or 11 if can detect temperature sensor set on the indoor heating tube of data acquisition controller and user;
By the contrast of two flow measurement devices in the system being had or not as can be known the generation of dehydration situation in the heat supply, perhaps whether two flowmeters are accurate.If two meter readings differences as can be known, system has the generation that the inaccurate or system of flowmeter loses the regimen condition, at this moment can be by shut-off valve 22 be turn-offed, and the mode that inserts proving flowmeter between joint 11 is successively checked, the definite reason that differs with very fast definite generation two meter readings, and can determine to take place the concrete floor of dehydration;
For the user who in a period of time, does not need heat supply, or to the user of indivedual improper interference heat supplies, can will cross over the mode that valve is opened fully accordingly simultaneously by turn-offing corresponding shut-off valve 5 and 22, and force to realize stopping purpose relevant user's heating with manual mode;
Adjust being positioned at the high-rise aperture of respectively crossing over valve, can realize allowing upright the connecing of portion of hot flow out from common riser, thus the heat of heat supply between can balance layer.
Carrying out above-mentioned inspection and when operation as can be seen, it is indoor not need to enter the user, and above various operations all are to carry out at shared pipeline enclosure, therefore can not exert an influence to arbitrary user.
But to the computer system that is positioned at heat supply control center, this just carries out the heat scheduling of heating network and adjusts the parameter that science is provided for heat supply control center to the equal long-distance transmissions of all heat supply data of total system monitoring.
