Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
As Figure 1-3, the control method of carbon-dioxide fire engine automatic control system, comprises the following steps:
Detect flow, pressure and the temperature at input duct 3, outlet pipe 4 places by sensor, and the data that detect are passed to computer;
Computer Analysis numerical value, according to the size of the electronic valve body folding on numerical value adjusting input duct 3, outlet pipe 4, controls flow and pressure.
Before input duct 3 feed liquors, computer is collected voltage parameter, current parameters and the temperature data in CO2 extinguishment system, judges whether this system meets service condition.This is operating as preliminary activities, guarantees after running environment, starts to carry out next step operation, safe and reliable.
Carbon-dioxide fire engine automatic control system, comprises computer, vapourizing unit and for controlling the control cabinet 1 of vapourizing unit;
Vapourizing unit comprises vaporizer 2, and vaporizer 2 is connected with respectively with the input duct 3 of control valve 5 and outlet pipe 4; Input duct 3 and outlet pipe 4 are provided with flowmeter 7 and electric control valve 6, and flowmeter 7 is provided with flow sensor, pressure sensor and the temperature sensor for passing to Computer signal.
On input duct 3 and outlet pipe 4, be equipped with Pressure gauge 10.Pressure gauge 10 is for field observation provides numerical parameter, easy to use.
Vapourizing unit comprises that 2, two vaporizers 2 of two vaporizers are connected with input duct 3 and outlet pipe 4 respectively by subtube 8, and subtube 8 is provided with control valve 5.Can select by control valve 5 direction of flowing through, according to the actual requirements, the number of the vaporizer 2 of choice for use.
Preferably, outlet pipe 4 is provided with safety valve 9.The safety coefficient of raising equipment.
On input duct 3 and outlet pipe 4, be enclosed with protective layer.Protective layer prevents that pipeline is corroded, and guarantee system is normally used.
Carbon-dioxide fire engine automatic control system and control method thereof that above-described embodiment provides, by sensor, can control accurately the value range of flowmeter 7, computer receives the numerical information that sensor sends, in the time that needs regulate, the unlatching size of controlling electric control valve 6 regulates; In the time that data exceed the value range of safety and stability, each sensor can be made response simultaneously, transfers data on computer, and computer will send warning, then stops the work of electrically operated valve, has protected the security of complete equipment.This system, not only measures accurately, adopts automation control, also has higher security, applied widely, is particularly useful in removable mineral building.
When concrete operations:
First, computer is collected the temperature data (T) transmitting from voltage parameter (V), current parameters (I) and the temperature sensor of control cabinet 1.Judge that whether system meets the condition of operation, as meet service condition,, opens the control valve 5 of feed liquor.After control valve 5 is opened, by being connected to flow sensor (S) in input duct 3, data upload that pressure sensor (P) is read to computer, determine whether and need with control electric control valve 6(E) control to adjust valve 5.As need, control is controlled by remote transfer signal, allows each data in input duct 3 remain within the scope of the safety and stability setting.
Through the conversion of vaporizer 2, carbon dioxide becomes gaseous state from liquid state.At this moment open the control valve 5 of giving vent to anger, after control valve 5 is opened, the data upload that the flow sensor (S), pressure sensor (P), the temperature sensor (T) that connect on outlet pipe 4 are read, to computer, judges whether to need with controlling electric control valve 6(E) control.As need, control is controlled by remote transfer signal.
If there is electric control valve 6 to exceed the safe range setting, each sensor can be made response simultaneously, transfers data on computer, and computer will send warning, then stops the work of electrically operated valve, has protected the security of complete equipment.
Wherein, the measured scope of former flowmeter 7 is: 0.25～2.5m
3/ h, pressure sensor control range is: 0～3MPa can only measure in fixed range.And this systemic-function has improved certainty of measurement greatly, measurement category can be controlled in the safe range of wanting to set (as flowmeter 7 can steadily be set in 2m
3/ h; pressure setting is stabilized in 2.5MPa); so just can more stable and accurate measurement; this system has also added sensor and automated data acquisition system; whether the ruuning situation of each sensor normally all can be reflected in the integrated control system panel of main frame; if find to have departed from the numerical value of setting range, sensor quits work automatically, thus the security that can protect whole system equipment to use.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
