Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Examples
Fig. 1 is a flowchart of a method for regulating flow of a heating pipe network according to an embodiment of the present invention, where the method can be executed by a device for regulating flow of a heating pipe network according to an embodiment of the present invention, and the device can be implemented in a software and/or hardware manner. Referring to fig. 1, the method may specifically include the following steps:
and S101, receiving monitoring signals from each monitoring mechanism.
Wherein, the monitoring mechanism can be a corresponding sensor for monitoring temperature difference, pressure, temperature, liquid level, flow, pressure difference, heat or water quality PH value and the like. The intelligent controller can also realize the control function of other independent signals, and can be singly connected with a certain signal to realize the function of the traditional control valve. The type of the monitoring signal which is connected in can be determined according to the requirement, for example, the energy control valve can realize the function of the temperature control valve when the temperature signal is connected in independently; the energy control valve can realize the functions of a constant pressure holding valve or a constant pressure relief valve by independently accessing the pressure signal; the flow control valve can be realized by independently accessing the flow signal; the function of the electric regulating valve can be realized by independently accessing the opening control signal. Specifically, each monitoring mechanism sends the monitored monitoring signal to the intelligent controller, and the intelligent controller receives the monitoring signal from each monitoring mechanism.
And S102, applying a set calculation rule, and calculating the actual energy consumption value of the current pipe network area according to the monitoring signal.
Specifically, the energy consumption value is usually related to pressure, flow, temperature and specific heat capacity of a medium, and according to a set calculation rule, the received monitoring signal is subjected to calculation processing, and the actual energy consumption value of the current pipe network area is obtained through calculation.
S103, comparing the actual energy consumption value with a preset energy consumption value to adjust the flow of the heat supply pipe network by controlling the increase or decrease of the valve openness of the energy control valve.
Specifically, the system presets a preset energy consumption value, which is an energy base value indicating that the energy consumption is within a normal energy consumption range. In a specific example, if the calculated actual energy consumption value is 50GJ and the preset energy consumption value is 45GJ, the calculated energy deviation value is +5GJ, which is an energy consumption exceeding state. At the moment, the flow of the heat supply pipe network is reduced by controlling the valve opening of the energy control valve to be reduced. Wherein GJ represents the unit of energy kilojoules.
Therefore, in the technical scheme of the application, the energy control valve can use a proportional-integral electric control valve as a main body and simultaneously access a plurality of signals, an intelligent controller control chip in the energy control valve writes in an execution program, flow, pressure and temperature signals acquired simultaneously are input into a calculation chip of the intelligent controller according to an energy conversion formula, the actual energy consumption value of a pipe network area controlled by the valve is calculated, and then the action of the valve is controlled by the actual energy consumption value. In addition, a wireless transmission function can be additionally arranged on an electric actuator of the energy control valve, so that the wireless remote control and monitoring functions are realized.
In the embodiment of the application, monitoring signals from all monitoring mechanisms are received; applying a set calculation rule, and calculating the actual energy consumption value of the current pipe network area according to the monitoring signal; and comparing the actual energy consumption value with a preset energy consumption value so as to regulate the flow of the heat supply pipe network by controlling the increase or decrease of the valve opening of the energy control valve. Compared with the traditional mode of regulating the flow through the flow, on one hand, the actual energy consumption value can be used as the standard when a plurality of signals are changed, and the regulation precision is improved; on the other hand, the type of the energy control valve can be switched according to the actual requirement, and the energy-saving and balance adjusting effect is realized.
On the basis of the above technical solution, before applying the set calculation rule and calculating the actual energy consumption value of the current pipe network region according to the monitoring signal, the method further includes: if the pressure difference of the current pipeline is detected to be larger than the set pressure difference threshold value, the flow of the current pipeline is determined to be larger than the set flow threshold value, and the valve opening degree of the energy control valve is reduced to control the flow to be reduced to the set flow threshold value; and if the detected pressure difference of the current pipeline is smaller than the set pressure difference threshold value, determining that the flow of the current pipeline is smaller than the set flow threshold value, and increasing the valve opening of the energy control valve to control the flow to be increased to the set flow threshold value.
Specifically, in the actual application process, due to other reasons such as valve blockage, the pressure of the current pipeline may be suddenly increased, and the deviation between the calculated actual energy consumption value and the preset energy consumption value is large in this case. Therefore, in order to avoid such a situation, before the set calculation rule is applied and the actual energy consumption value of the current pipe network area is calculated according to the monitoring signal, it is first detected whether the pressure difference change of the current pipe is too large, for example, the pressure difference change is larger than the set pressure difference change threshold, and the flow change is caused by the pressure difference change, which indicates that the flow of the current pipe is larger than the set flow threshold, the valve opening of the energy control valve is reduced, and the flow is reduced to the set flow threshold. In addition, if the detected pressure difference change of the current pipeline is smaller than the set pressure difference threshold value, the flow of the current pipeline is smaller than the set flow threshold value, at this time, the valve opening degree of the energy control valve is increased, and the flow is increased to the set flow threshold value.
In a specific example, whether or not the temperature is changed in the adjustment process is realized, and the temperature is not changed will be described as an example. When the pressure difference fluctuation of the pipeline causes flow change but the temperature is unchanged, the opening of the valve is controlled to change, so that the flow is kept unchanged, and the energy consumption is unchanged on the premise of keeping the temperature unchanged. For example, if the pressure difference suddenly increases to cause the flow to increase, but the temperature of the medium does not change, the actual energy consumption will increase if the valve does not act, so the opening of the valve is forcibly reduced to restore the flow to the original state; on the contrary, the pressure difference is suddenly reduced to reduce the flow rate, but the temperature of the medium is not changed, and at the moment, if the valve does not act, the actual energy consumption is reduced, so that the opening degree of the valve is forcibly increased to restore the flow rate to the original state.
On the basis of the above technical solution, before applying the set calculation rule and calculating the actual energy consumption value of the current pipe network region according to the monitoring signal, the method further includes: if the temperature of the medium in the current pipeline is detected to be greater than the set temperature threshold, reducing the valve opening of the energy control valve to control the temperature of the medium to be reduced to the set temperature threshold; and if the temperature of the medium in the current pipeline is detected to be smaller than the set temperature threshold, increasing the valve opening of the energy control valve to control the temperature of the medium to be increased to the set temperature threshold.
In a similar way, when the temperature of the medium changes, the opening of the control valve changes, so that the flow of the pipeline is forced to change, and the effect of unchanging energy consumption is achieved. For example, the valve opening degree is increased when the medium temperature decreases, and the valve opening degree is decreased when the medium temperature increases, so that the energy consumption is always kept unchanged.
In addition, although the above description applies the case where the pressure difference varies without changing the temperature, and the case where the temperature varies without changing the pressure, there is no limitation in the actual application process. That is, when the flow rate of the pipe pressure fluctuation is changed and the medium temperature is also changed, the same effect can be achieved
In the signal intelligent controller that the probe was gathered, through calculating the difference between actual energy consumption value and the energy consumption value of predetermineeing, the automatic control valve door opening degree makes the energy consumption value tend towards the stability.
Fig. 2 is a flowchart of a method for regulating a flow rate of a heat supply pipe network according to another embodiment of the present invention, which is implemented on the basis of the foregoing embodiment. Referring to fig. 2, the method may specifically include the following steps:
s201, receiving monitoring signals from each monitoring mechanism.
Optionally, the monitoring signal includes a medium temperature signal, a pressure signal and a flow signal. In the embodiment of the present application, the monitoring signals are exemplified by a medium temperature signal, a pressure signal, and a flow rate signal. In one specific example, if the medium is water, the pressure signals include a supply pipe pressure signal and a return pipe pressure signal.
S202, a set heat calculation formula is applied, and the actual energy consumption value of the current pipe network area is calculated according to the specific heat capacity of the current medium, the medium temperature signal and the flow signal.
Setting a heat quantity calculation formula as Q ═ CL (T1-T2), Q is an actual energy consumption value, C is the specific heat capacity of the current medium, and if the current medium is water, C is the specific heat capacity of the water and is 4.2 multiplied by 1000J (Kg. ℃); l is the pipe flow, i.e., the mass of the medium; T1-T2 is the temperature change of the medium, namely the temperature difference between the supply water temperature and the return water temperature. Therefore, the actual energy consumption value of the current pipe network area can be calculated by applying the set heat calculation formula.
In a specific example, the calculation method corresponding to the above-mentioned set heat calculation formula may be programmed, and the program may be written into a chip of the intelligent controller. According to the formula, the received water supply temperature T1, the received water return temperature T2 and the pipeline flow L are transmitted back to the intelligent controller through the data line by the sensor, and the actual energy consumption value is calculated according to the calculation formula.
And S203, comparing the actual energy consumption value with a preset energy consumption value.
S2041, if the actual energy consumption value is larger than the preset energy consumption value, reducing the valve opening to reduce the flow of the heat supply pipe network until the actual energy consumption value is equal to the preset energy consumption value, and stopping reducing the valve opening.
In a specific example, if the calculated actual energy consumption value is 50GJ and the preset energy consumption value is 45GJ, the calculated energy deviation value is +5GJ, which is an energy consumption exceeding state. At the moment, the flow of the heat supply pipe network is reduced by controlling the valve opening of the energy control valve to be reduced. And stopping reducing the opening of the valve until the actual energy consumption value is equal to the preset energy consumption value, and keeping the corresponding position unchanged.
S2042, if the actual energy consumption value is smaller than the preset energy consumption value, increasing the valve opening to increase the flow of the heat supply pipe network until the actual energy consumption value is equal to the preset energy consumption value, and stopping increasing the valve opening.
In a specific example, if the calculated actual energy consumption value is 40GJ and the preset energy consumption value is 45GJ, the calculated energy deviation value is-5 GJ, which is the energy consumption non-compliance state. At the moment, the flow of the heat supply pipe network is improved by controlling the increase of the opening of the energy control valve. And stopping increasing the opening of the valve until the actual energy consumption value is equal to the preset energy consumption value, and keeping the corresponding position unchanged.
In the embodiment of the application, a set heat calculation formula is applied, and the actual energy consumption value of the current pipe network area is calculated according to the specific heat capacity of the current medium, a medium temperature signal and a flow signal; comparing the actual energy consumption value with a preset energy consumption value; if the actual energy consumption value is larger than the preset energy consumption value, reducing the opening of the valve to reduce the flow of the heat supply pipe network until the actual energy consumption value is equal to the preset energy consumption value, and stopping reducing the opening of the valve; and if the actual energy consumption value is smaller than the preset energy consumption value, increasing the valve openness to increase the flow of the heat supply pipe network until the actual energy consumption value is equal to the preset energy consumption value, and stopping increasing the valve openness. The heat supply pipe network flow can be effectively adjusted, and the effects of energy conservation and balance are achieved.
In addition, in the embodiment of the application, the actual purpose of adjusting the flow is to keep the energy consumed by the user unchanged, so that the actual energy consumption value is used as a measurement index, and an objective and accurate effect is achieved. In the prior art, by calculating the flow of a pipeline, energy is calculated in the application. The energy consumption value is calculated by setting a heat calculation formula according to the changes of the pressure, the flow and the temperature difference of the pipeline, and the actual energy consumption value of the water supply and return pipe at a user position is directly read, so that the room temperature can be reflected without waiting for the pipeline to run for a period of time after the adjustment is finished like the traditional method for adjusting the flow, and the system is directly debugged at one time according to the actual energy consumption value. Therefore, the effects of energy conservation and balance can be achieved in the true sense.
In addition, a single control signal source can be connected to be used as a single flow valve, a pressure valve and a temperature valve; and a plurality of signal sources can be connected to be used as energy control valves. In short, the function switching can be carried out according to the actual requirement. The energy control valve can be used for controlling the valve action by taking the actual energy consumption value as a reference when a plurality of signal parameters are changed.
In a specific example, fig. 3 shows an operation principle diagram of an energy control valve, and referring to fig. 3, P1 represents a water supply pipe pressure value, P2 represents a water return pipe pressure value, △ P-P1-P2 represent a pressure difference, a water supply temperature T1, a water return temperature T2 and a pipeline flow rate L, T1-T2 represent a temperature change of a medium, and 30 represents the energy control valve.
In a specific example, fig. 4 shows a schematic structural diagram of an energy control valve, and referring to fig. 4, the energy control valve 30 includes a body 41 representing the energy control valve and a body 42 representing the valve, and the intelligent controller is not shown in fig. 4.
