Abstract
A temperature-sensing active actuator for pulsating super fine dried powder automatic fire extinguishing device, characterized in that, it comprises a cradle, a temperature control actuating element formed by a removable pin for upper end sensitization temperature control signal and a small compression spring uniformly distributed axially along the pin, a striking rod with one end coated by gelatinized red phosphorus and in the shape of striking needle, the other end is in radial rabbet joint with the lower end of the removable pin, a screw nut sleeved on the striking needle with a upward opening, an actuation heat-sensitive wire extending to a plurality of fire extinction, and a support bracket cover, the heat-sensitive wire comprises multi-ply cotton yarn and celluloid coating. The invention realizes quick actuation and high dependability.
Description
Technical field
The spontaneous starter of the temperature-sensitive that automatic fire extinguisher of puluse ultrafine dry powder is used belongs to the automatic fire extinguisher field.
Background technology
Extinguishing chemical in the existing ultra-fine dry powder fire extinguisher is to lean on the pressure effect of Compressed Gas in the gas bomb to spray out.Its shortcoming is that fire extinguisher itself is exactly a pressure vessel, the casualty accident of blasting easily.The 2nd, easy gas leakage need be made regular check on, the maintenance trouble.
Summary of the invention
The spontaneous starter of the temperature-sensitive that the object of the present invention is to provide a kind of automatic fire extinguisher of puluse ultrafine dry powder to use.When the temperature-sensing element of extinguishing device is experienced flame or environment temperature rising, temperature-sensing element is out of shape or breaks, removable pin ejects, the impact bar fast moving, impinge upon on the starting element that is fixed on impact disc, starting element ignites and reaches the aerogenesis box gas generating agent that ignites rapidly, produces a large amount of gas and removes to spray powder extinguishing agent.
The invention is characterized in: it contains: support, experience the removable pin of temperature signal and the temperature control executive component that constitutes at its axial uniform small pressure spring by the upper end, one end scribbles gel red phosphorus and is the striker shape and radially rabbet the other end and removable pin lower end and make the impact bar that slides fast at rack inner wall under the removable pin effect, be enclosed within the startup heat-sensitive line that opening extends in the lead-in wire bolt of above-mentioned striker direction and to a plurality of fire extinguishing points, the anchor leg bolt each to heat-sensitive line and fixedly be connected on the bump dish of support inside bottom, bracket cover in addition.
Described heat-sensitive line is the multiply cotton that speckles with celluloid glue medicine coating.
Speckle with celluloid glue medicine coating on the multiply cotton yarn in the described heat-sensitive line, it is constructed as follows by weight: it is made of for (2-9) % ethyl acetate solution medicine and celluloid concentration, and their weight ratio is 1: 1.Medicine is made of potassium chlorate and sucrose, and their weight ratio is followed successively by (50-75) % and (50-25) %.
Described impact bar axially is being wound with the big stage clip of percussion close along removable pin one side.
Described impact bar top scribbles gel red phosphorus.
Use proof: it have start fast, reliability is high, cost is low, use and advantage such as easy for installation.
Description of drawings
Fig. 1: the spontaneous starter of the temperature-sensitive that automatic fire extinguisher of puluse ultrafine dry powder is used
The sectional view of the A-A of Fig. 2: Fig. 1
The specific embodiment
See Fig. 1 and Fig. 2 for details.In Fig. 2, the 1st, be enclosed within the metal shell in the sprinkler head seat 4, the 14th, withstand on the upper end of removable pin 2 and the glass envelope between metal shell 1 inwall, metal shell 1, sprinkler head seat 4 and temperature-sensing element of glass envelope 14 common formations.The 3rd, the small pressure spring on the axle of removable pin 2, it and removable pin 2 be common to constitute the temperature control executive components.The lower end of removable pin 2 is in the cannelure that radially is stuck in impact bar 7.One end of impact bar 7 scribbles gel red phosphorus and becomes striker shape, and the other end is stuck in split pin 15 that big stage clip 6 tightens on the sprinkler head seat 4 on the axle of impact bar 7 and by axial step.Impact bar 7 can slide in the endoporus of the inwall of support 5 and the set bolt 9 that is fixed on support 5 inwalls fast, and the heat-sensitive line of using as starting element 13 is enclosed within opening in the lead-in wire bolt 12 of striker.Heat-sensitive line 13 is introduced from the endoporus of bolt 16, and a plurality of side openings that are positioned at peripheral direction from the bump dish 10 of the inside bottom that is fixed on support 5 by bolt 16 and nut 17 cause a plurality of fire extinguishing points again, have 4 fire extinguishing points in the present embodiment.The 11st, bracket cover.
When temperature-sensing element is glass envelope 14 temperature-sensing element distortion or break when experiencing flame or environment temperature and rising to set point of temperature, removable pin 2 ejects, impact bar 7 moves rapidly, strike against the heat-sensitive line 13 that is fixed on the impact disc 10, heat-sensitive line 13 is painted on the gel red phosphorus of the striker end of impact bar 7 and lights, and reaches the aerogenesis box along heat-sensitive line 13 rapidly, and gas generating agent ignites, produce a large amount of gas, remove to eject powder extinguishing agent.Heat-sensitive line 13 both can be ignited by gel red phosphorus in the back that is hit, also can spontaneous combustion when the scene of fire environment temperature reaches 170 ℃.In the present embodiment, heat-sensitive line 13 is in the ethyl acetate solution of the multiply cotton celluloid that impregnated in potassium chlorate 55 gram, sucrose 45 grams and 4%, takes out that the nature airing makes.
Compare with existing startup source, it has following advantage:
1, without high-pressure gas cylinder, the medicament that adopts the Oxidizing and Reducing Agents mixing is as power source.
2, can use existing temperature-sensing element, need not expensive sense cigarette, temperature sensing device, without power supply, cost is low to reach tens of times.
3, installation, use, easy to maintenance.
Automatically starting when 4, chance fire or scene of fire environment temperature reach 170 ℃.
