Abstract
An automatic fire-extinguishing valve for fire accident is composed of main body, valve core and its drive mechanism, and drive controller. Said drive controller consists of a current loop composed of contact thermometer, power supply and electrothermal wire and the fusible wire wound by said electrothermal wire. When ambient temp reaches a predifined value, the contact thermometer is conducted to make electrothermal wire generate heat to fuse off the fusible wire. Under the action of fire-extinguishing agent pressure, the valve is opened to spray out the fire-extinguishing agent.
Description
The invention belongs to fire-fighting equipment, particularly a kind of universal automatic fire-extinguishing valve for fire accident.
The automatic fire-extinguishing valve for fire accident (comprise the inhibition shower nozzle, it has the double action of shower nozzle and valve) that extensively adopts both at home and abroad has fusible metal to connect the piece type at present, chemical little column type, glass tubular type etc.Its principle be utilize fusible metal under predetermined temperature, to melt and glass tube in thermally-expansible liquid under predetermined temperature, glass tube burst and with valve open, thereby with the extinguishing chemical ejection, realize self-extinguishing.
Through practice test for many years, confirm that they have following defective: one, error is big, and the temperature error more than 15% is arranged approximately; Two, response speed is slow, and when temperature sharply rose, because heat absorption fusing and expanded by heating need a period of time, when often temperature was above several times of predetermined temperature, its valve was not also opened as yet, thereby misses the best opportunity of fire extinguishing, has lost the effect of self-extinguishing; Three, poor reliability.
The objective of the invention is to be to design a kind of precision height, response is fast, reliability height, the automatic fire-extinguishing valve for fire accident of highly versatile.
Major technique measure of the present invention is as follows:
A kind of automatic fire-extinguishing valve for fire accident has valve body, spool, spool driving mechanism and drives controlling organization.Wherein, drive controlling organization and comprise a contact temperature meter, fusible line, power supply and heating wire.Heating wire is wrapped on the fusible line, fusible line is connected between spool driving mechanism and the stiff end, two terminals of power supply, heating wire, lead and contact temperature meter constitute current loop, experience environment temperature by the contact temperature meter, when environment temperature reaches or surpass predetermined temperature, conducting between two terminals, thereby the connection circuit, the electrothermal wire heating fuses fusible line, open valve thereby discharge the spool driving mechanism, extinguishing chemical sprays by valve.
The present invention's spool can be designed to piston type or rotary spool formula, and they can or drive by lever location, and its frame for movement can be selected according to different structure type.
Because adopt said structure, precision of the present invention and reaction speed just depend on the contact temperature meter, and the error of contact temperature meter is less than 1 ℃, and reaction speed is very fast again, so of the present invention have a precision height, reaction soon, reliability height, advantages such as highly versatile.
Below in conjunction with accompanying drawing and the embodiment description detailed in addition that provide thereof to the present invention:
Fig. 1: the profile that is a kind of rectilinear motion valve of the present invention.
Fig. 2: the main pseudosection that is a kind of valve that rotatablely moves of the present invention.
Fig. 3: the vertical view that is Fig. 2.
Among the figure: 1, valve body: 2, piston; 3, middle sealing ring; 4, line colludes; 5, hold-down screw on the safety fastener; 6, safety fastener; 7, battery; 8, outer cover; 9, fusible line; 10, heating wire; 11, lever; 12, contact temperature meter; 13, cover plate hold-down screw; 14, cover plate; 15, support hold-down screw; 16, lever dolly; 17, lower seal; 18, go up sealing ring; 19, hold-down screw under the safety fastener; 20, lead; 21, fixed leg; 22, change the core fixed cover; 23, hollow plug; 24, change mandrel; 25, spool; 26, valve core seal ring; 27, spring; 28, fixed head; 29, extinguishing chemical outlet.
Fig. 1 is two kinds of structural shapes of the present invention's " automatic fire-extinguishing valve for fire accident " to Fig. 3, Fig. 1 To utilize the pressure of extinguishing chemical self to open a kind of rectilinear motion fire valve of valve, simultaneously its this Body also has the effect of shower nozzle concurrently. Fig. 2, Fig. 3 utilize the bounce that presets spring to open valve A kind of fire valve that rotatablely moves, certain straight-line valve also can utilize the bounce-back of presetting spring Power realizes. The principle of these two kinds of patterns is all the same, all is to come valve-off with fusible line 9, Its principle is as follows: twine heating wire 10 on the fusible line 9, and with lead 20 with heating wire 10 and Contact temperature meter 12 and battery 7 link, and when temperature reached predetermined value, the contact temperature meter was connected, Fusible line is blown in heating wire 10 heating, and valve is under extinguishing chemical self pressure-acting or preset Automatically open under the effect of springback power, thus the self-extinguishing of ejection extinguishing chemical.
Embodiment 1:
As shown in Figure 1, piston 2 is arranged in the valve body 1, with cover plate 14 piston 2 is covered in valve body 1, lever 11 is pushed down piston 2, and the far-end of lever 11 is with fusible line 9 online the colluding on 4 that be strained and fixed, and line colludes 4 usefulness nuts and is fixed on the valve body 1, and can adjust up and down.In order to prevent to leak, when fusible line 9 is in not off-state, be to utilize to go up sealing ring 18 sealings, when fusible line is in off-state, be sealing ring 3 and lower seal 17 sealings in utilizing.Fusible line 9 is wound with heating wire 10, and with lead 20 with heating wire 10, battery 7 and contact temperature meter 12 articulatings, when environment temperature reaches predetermined value, the contact temperature meter is connected, fusible line 9 is blown in heating wire 10 heatings, and piston 2 is under the effect of extinguishing chemical self pressure, lever 11 is backed down, and extinguishing chemical sprays fire extinguishing automatically from the exit.
Fusible line 9 can adopt macromolecular compound (as nylon wire, formal wire etc.) or carbon fiber etc., can blow down or the fine rule of oxidation scission gets final product at 100 ℃～400 ℃.Cover plate 14 usefulness cover plate hold-down screws 13 are fixed on the valve body 1, and lever 11 usefulness pins are fixed on the lever dolly 16, and rotation that can be freely.Lever dolly 16 usefulness sunk screws 15 are fixed on the cover plate 14, disconnected in order to prevent that fusible line 9 from shaking in transit, so by screw 19 pulling that is fixed, safety fastener screw 19 should be taken off the upper end of its safety fastener 6 during installation in the lower end of the far-end of lever 11 and safety fastener.By hold-down screw 5 it is connected with valve body 1.
