Embodiments in accordance with the present invention, using the passive automatic spray valve 300 of temperature memory alloy, in certain fire-fighting region
One group of controllable water control switch valve of temperature of interior design, this device is the standard thread and temperature memory alloy control by pipe fitting
The standard thread connection composition of valve processed, water-carrying capacity switch.When there is the condition of a fire, temperature memory alloy control valve detects environment temperature
Degree is abnormal to be raised, and during higher than set temperature value, temperature memory alloy control valve is opened, and aqueous medium can be conveyed to institute through pipe fitting
There is spray head to spray fire extinguishing, now, there is water to flow in water-carrying capacity switch, catch therein can drive after being influenceed by water jet propulsion
Magnetic source produces axial displacement and oppresses back-moving spring contraction, and now tongue tube is influenceed by the magnetic line of force, two panels reed endpoint location
Different polarity are produced, by the switching signal after closure of attracting each other to output line " logical ", the signal can be passed by output line
It is defeated by correlated communication equipment.After condition of a fire elimination, when environment temperature is less than set temperature value, temperature memory alloy control valve is closed
Close and be stopped, the magnetic source in water-carrying capacity switch drives magnetic source to set back in the presence of back-moving spring thrust, tongue tube
Nearby without externally-applied magnetic field interference, the reed of two panels opposed polarity will separate, and the switching signal to output line output " disconnected " is simultaneously transmitted
To correlated communication equipment.
In actually used installation, for protection object, place and situations such as temperature requirements, by temperature memory alloy control
The connection that is screwed is carried out between the standard thread and pipe fitting, shower nozzle of the water side of valve processed, while by water-carrying capacity switch according to need
Safety, suitable position are arranged on, the output line switched by water-carrying capacity is connected with centralized-control box, you can realization " will be opened
Close " function of signal transmission, it is also possible to the present invention is integrated in automatically control in the lump by centralized-control box with other equipment it is
In system platform, the function of information linkage and centralized management is realized.
When there is fire or environment temperature is raised extremely, the marmem on temperature memory alloy control valve is subject to
The influence of environment temperature and produce deformation, make temperature memory alloy control valve in magnetic ring component move up, by the magnetic line of force
Zone of action dynamic temperature memorial alloy control valve in core assembly move upwardly together, medium flush-out valve under the effect of the pressure
Door simultaneously starts to spray work by shower nozzle, now has water to flow in water-carrying capacity switch, and catch is driven magnetic source by water hammering effects
It is common to produce axial displacement, and back-moving spring contraction is oppressed, now tongue tube is influenceed by the magnetic line of force, two panels reed endpoint location
Different polarity are produced, by the switching signal after closure of attracting each other to output line " logical ", the signal can be passed by output line
Centralized-control box is defeated by, transmission and the sending function of relevant information are realized by centralized-control box.
When environment temperature recovers normal after condition of a fire elimination, the memorial alloy on temperature memory alloy control valve shrinks and makes magnetic
Ring assemblies are moved down in the presence of valve interior biasing spring makes temperature memory alloy control valve to close, and recovers normal monitoring shape
State, when the water-carrying capacity of water-carrying capacity switch is less than flow is started, the magnetic source in water-carrying capacity switch is in the presence of back-moving spring thrust
Magnetic source is driven to set back, tongue tube is nearby without externally-applied magnetic field interference, and the reed of two panels opposed polarity will separate, defeated to output line
Go out the switching signal of " disconnected " and be transferred to centralized-control box, centralized-control box is to be stopped.
The beneficial effect of the present apparatus be absent from the scene in unattended or related personnel, the disaster field such as mobile vehicle,
The output function of " open and close " signal in real time is capable of achieving, the range of application that temperature memory alloy controls valve has been widened, is that information is passed
Defeated, centralized management is had laid a good foundation.
Administrative staff can in time understand condition of a fire position, number information equicorrelated case, and carried out for the condition of a disaster scene and
When cleaning and maintenance.
It is connected with communication module or region, common control equipment and is capable of achieving teletransmission alarm or configured information, it is also possible to
The present invention is integrated in automatic control system.
Real-time Communication for Power fire-distinguishing alarming system according to an embodiment of the invention, it is to avoid occur in fire protection pipeline 100 anhydrous
Situation；Due to energy real-time monitoring fire condition, fire fighting monitoring side and fire-fighting supervision can in real time understand fire spot,
Be conducive to the quick control of fire the condition of a disaster；Particularly, for underground pipe gallery wait fire-fighting point, occur fire when, due to can not and
The Shi Faxian condition of a fire, it is possible to cause large-scale fire the condition of a disaster, meanwhile, there is concrete on fire in underground pipe gallery, due to cannot be accurately true
Determining fire point could solve due to the various problems that fire triggers, it is necessary to manually carry out substantial amounts of investigation, and use institute of the present invention
After stating technical scheme, fire-fighting supervisor can immediately grasp rare personnel activity's point fire such as underground pipe gallery to be occurred exactly
Point, is conducive to the quick solution of fire the condition of a disaster；There is full-automatic firefighting monitoring system of the present invention simple structure, manufacture to hold
Easily, low production cost and the characteristics of easily construct
