Described central regulation and control center, for different systems, manually input system information, comprises a building information, pipe network information.
Described central regulation and control center, the building of a typing information comprises position, building the area of Lou Dong in pipe network, the pipe network information of typing comprises pipe diameter, duct length.
Described central regulation and control center, calculates a building design discharge according to a building information, and compares with actual flow, output control signal.
A regulation and control unit, described building, its controller can gather calorimeter data, electrodynamic balance valve opening state.
A regulation and control unit, described building, its electrodynamic balance valve body is static balancing valve, YE is detachable.
Design discharge and actual flow compare, and when actual flow is less than design discharge, increase electrodynamic balance valve opening, when actual flow is greater than design discharge, reduce electrodynamic balance valve opening.
The utility model beneficial effect is as follows:
(1) the utility model utilizes the existing equipment facility of heat measuring system, does not need to increase in addition pipe-line equipment, annex, and electrodynamic balance valve actuator is detachable, reusable, and initial cost is little, and device service efficiency is high.
(2) the utility model is simple, practical, and the property grasped is strong.
(3) by the utility model, can realize the auto hydraulic balance adjustment of heating system, save a large amount of manpower and materials, make adjusting work simple, efficient, accurate.
Accompanying drawing explanation
Accompanying drawing is structure principle chart of the present utility model.
The specific embodiment
As shown in drawings, the heat measuring system auto hydraulic balance regulator that the utility model provides, comprise and be contained in a feed pipe Shang building calorimeter 4, be contained in the electrodynamic balance valve 5 on return pipe, carry out a building data acquisition and a regulation and control unit 3, the building uploaded, carry out the central processing unit 2 of data storage, processing and carry out central authorities' regulation and control center 1 of system auto hydraulic balance adjustment.
Central authorities' regulation and control center 1, can, according to an integral layout input building information of community, comprise position and area.Can pass through specific numbering, make system automatically identify the building of near-end, far-end.According to area, calculate the design discharge in building or provide design discharge by design data, carrying out manual typing.
Lou Dong regulation and control unit 3 can gather the data of a building calorimeter 4, comprises the warning message of heat accumulative, integrated flux, instantaneous heat quantity, instantaneous delivery, supply water temperature, return water temperature and calorimeter.Lou Dong regulation and control unit 3 also can gather the valve opening of electrodynamic balance valve 5, and output increases or reduce the instruction of valve opening.
The ultrasonic calorimeter that calorimeter 4 is telemetering type, relies on pressure reduction to obtain the mode of flow compared to other, and the instantaneous heat quantity data that ultrasonic calorimeter records are more accurate, credible.
The valve body of electrodynamic balance valve 5 is static balancing valve, be the valve member that must install in heat measuring system, but heat measuring system does not require that it is power type.The utility model comprises dismountable YE, after system debug, YE can be removed, and is applied to the debugging of other system.
Central authorities' regulation and control center 1 contrasts the instantaneous delivery of the design discharge of calculating or inputting and calorimeter 4 collections, and comparing result is issued to Lou Dong regulation and control unit, by Lou Dong regulation and control element output signal, controls electrodynamic balance valve opening.When instantaneous delivery is greater than design discharge, balanced valve aperture reduces, and when instantaneous delivery is less than design discharge, compensation flap aperture increases.
Said method to the regulation and control of single building effectively, when carrying out the auto hydraulic balance adjustment of system, the regulatory process of system is set at central authorities' regulation and control center 1, according to certain method, give each building temporary transient design discharge, realize the coarse adjustment of system, after system coarse adjustment completes, the relation according to each building with design discharge, carry out one by one the thin tuning of Lou Dong, finally reach the balance of whole system.
The method of coarse adjustment or thin tuning is: the instantaneous delivery that 1 pair, the central regulation and control center temporary transient design discharge of calculating or inputting or design discharge and calorimeter 4 gather contrasts, and comparing result is issued to Lou Dong regulation and control unit 3, by Lou Dong regulation and control unit 3 output signals, control electrodynamic balance valve 5 apertures.When instantaneous delivery is greater than temporary transient design discharge or design discharge, balanced valve aperture reduces, and when temporary transient design discharge or instantaneous delivery are less than design discharge, compensation flap aperture increases.
Lou Dong regulation and control unit 3 adopts RS485 wired connection with the connected mode of a building calorimeter 4, electrodynamic balance valve 5, Lou Dong regulation and control unit 3 carries out wireless connections with central processing unit 2 by the mode of GPRS, and central processing unit 2 is connected with the mode of central regulation and control center 1 by Internet.
