Description
Technical Field
The invention relates to the technical field of fire fighting, in particular to a novel full-automatic fire fighting spray fire extinguishing device.
Background
Among various disasters, the fire disaster is one of the main disasters which most often and most generally threaten public safety and social development, and the direct property loss caused by the fire disaster in China is up to billions of yuan every year, the number of people dying due to the fire disaster in the year is up to 2000 people, and the cases of people injury caused by the fire disaster can not be counted, so that people are surprised. Therefore, the fire fighting research on how to reduce the harm caused by fire or how to kill the big fire is a big civil affair which concerns the property safety and the life safety of every family and is not easy to be solved.
The existing automatic fire-fighting spraying system mainly comprises a closed fire-fighting spraying system and an open fire-fighting spraying system. The principle of closed fire sprinkler system is mainly that the shower head of indoor ceiling dress is equipped with the thermal expansion liquid, when indoor emergence condition of a fire and temperature reach 68 ℃ or above, the glass pipe is burst in the expansion liquid inflation, at first the high-order pond of fire control provides the water source, at this moment wet-type alarm valve can be opened automatically, pressure switch in the valve is automatic to be opened, and this pressure switch has root signal line and fire pump chain, the water pump is just automatic starting, then the spray pump provides the pipe network to the water in pond through the pipeline, whole fire sprinkler system begins work. The open fire-fighting sprinkler is provided with a smoke-sensitive probe for detecting smoke, when a fire disaster occurs in a site and the smoke reaches a certain concentration, the smoke-sensitive probe gives an alarm, the smoke-sensitive probe feeds back to an audible and visual alarm after the smoke-sensitive probe is confirmed by a host to give out sound or twinkle light to warn people, the smoke-proof fan is linked to start to discharge smoke, the electromagnetic valve of the deluge valve is opened, the sprinkling pump is linked to the electromagnetic valve, and the open sprinkler directly sprays water.
However, with the continuous use of the conventional automatic spraying fire-fighting spraying system, some drawbacks are gradually appeared, and the appearance of the drawbacks causes that the conventional automatic spraying fire-fighting spraying system cannot meet the high-standard use requirements of the contemporary society, and the following descriptions are now made for the defects of the conventional automatic spraying fire-fighting spraying system:
1. due to the change of the water supply pressure, the system often generates false alarm and generates unnecessary noise;
2. the system is complicated, the related electronic circuits are more, and once a certain link has a problem, the whole system cannot work normally.
Therefore, it is very important to design a brand-new full-automatic fire-fighting sprinkler device for solving the technical problems.
Disclosure of Invention
In view of the above, the present invention provides a novel full-automatic fire sprinkler to solve the above technical problems.
The invention is realized by the following technical scheme:
the novel full-automatic fire-fighting spray fire extinguishing device comprises a shell and an adjusting component for adjusting the flow of water flow;
the adjusting assembly comprises a paraffin wax thermal bulb arranged at the top end and one side in the shell, a paraffin wax thermal bulb fixing seat arranged in the shell and used for fixing the paraffin wax thermal bulb, and a plugging piece arranged at the output end of the paraffin wax thermal bulb;
two sides of the top of the shell are communicated with an external water pipe, and the bottom of the L-shaped shell is communicated with a spraying shower head;
the casing is provided with the valve main part through one side and is used for carrying out fixed stay to the casing.
Further, the plugging piece comprises a piston arranged at the output end of the paraffin wax thermometer bulb and a limiting spring arranged at the bottom of the piston and used for limiting the position of the piston in a low-temperature state.
Further, the bore that the casing inside wall meets with the piston increases from top to bottom in proper order, works as thereby the piston can produce the gap rivers in the gap outflow with the casing inside wall when from top to bottom pressure moves.
Further, the shutoff subassembly is including setting up in the sealed axle of paraffin wax bulb output, setting up in the sealed pad of opposite sex of sealed axle both sides and the elastic component that is used for avoiding sealed axle automatic re-setting.
Furthermore, the elastic part comprises a working spring arranged on one side of the sealing shaft, and the working spring is fixedly connected with the inner wall of the shell.
Further, a sealing ring is arranged on the working spring in contact with the sealing shaft.
Further, the paraffin wax bulb was set to a constant value of 46 ℃.
The invention has the beneficial effects that:
1. this novel full-automatic fire sprinkler puts out a fire, the accurate response that adopts the paraffin temperature bulb to carry out the temperature and opening of valve, reducible cost improves the response accuracy.
2. The novel full-automatic fire-fighting spray fire extinguishing device can be used as a valve to be installed in thousands of households, and can be directly connected with a fire-fighting pipeline or a tap water pipeline.
3. This novel full-automatic fire sprinkler extinguishing device does not need any electronic component and electric wire to arrange, uses through the cooperation of paraffin wax temperature package and shutoff piece, when the conflagration that takes place and site temperature reach 46 ℃, can realize automatic spray.
4. This novel full-automatic fire sprinkler extinguishing device, in case the scene of fire triggers the automatic spray back, can spray constantly continuously, need not worry that burning of spare part or burning of electric wire way and interrupt and spray.
5. In summary, the existing automatic spraying system is limited by the strength of the expansion material and the glass tube, and the automatic spraying can be realized only when the indoor temperature reaches above 68 ℃, but the temperature sensing device on the ceiling senses the temperature to start melting and blasting, which indicates that the indoor fire is great, and if people are trapped in the room at the temperature, the people are seriously burned or die, and the technical scheme of the application can realize automatic spraying only when the field temperature reaches 46 ℃, so that the most timely early-stage fire extinguishing is realized, the fire is prevented from rapidly spreading, the favorable time is won for manual fire extinguishing, the escape time is increased for escape personnel, and the possibility of injury is reduced for the escape personnel.
