Gas extinguishing system fire extinguishing agent leakage monitor and long distance control system
Technical field
The utility model relates to security against fire monitoring field, relates in particular to a kind of gas extinguishing system fire extinguishing agent leakage monitor and long distance control system.
Background technology
Gas extinguishing system refers to that fire extinguishing agent is stored in steel cylinder with liquid, liquid gas or gaseous state at ordinary times, the gas (comprising: steam, aerosol state) of usining during fire extinguishing sprays as firing-fighting medium, and in can be between guard plot, form the gas concentration of all directions homogeneous, and at least can keep this fire extinguishing scope to reach the dip time of regulation and stipulation, realize and put out the space of guard plot, three-dimensional fire.It is mainly used in being not suitable for arranging in the environment of the fire extinguishing systems such as water fire-extinguishing system, for example: for power plant, power station, chemical plant, pharmaceutical factory, and computer house, library, archives, treasure storehouse and telecommunication center etc.
The principle of work of gas extinguishing system is roughly: gas extinguishing system is connected with automatic alarm system, when automatic alarm system is received secondary warning (warning of simultaneously receiving smoke detector and heat detector just makes secondary report to the police), send out indicator signal to the console panel of gas extinguishing system, console panel is received after indicator signal, send instructions and start the solenoid valve at steel cylinder top, the valve at steel cylinder top is opened in solenoid valve action, makes air release in steel cylinder out.
Gas extinguishing system is in long-term storage process at present, because rubber seal is intermolecular, there is gap, therefore leaking may appear in fire extinguishing agent gas, cause the amount of fire extinguishing agent gas in steel cylinder to reduce, when serious, cause fire extinguishing agent system can not reach designing requirement, in the face of this kind of situation, the conventional solution in this area is at present: by the special manometric reading of testing staff's routine observation fire extinguishing agent, when manometric reading pressurizes and supplements fire extinguishing agent during lower than a certain value, to guarantee the amount of fire extinguishing agent, but the problem that this mode exists is: the force value of fire extinguishing agent varies with temperature and changes on the one hand, therefore by intuitively reading its accuracy of method of tensimeter numerical value, need to be considered, adopt on the other hand manual detection to be subject to the impact of the factors such as personal mood, sense of responsibility, accuracy is not high.
