Description
Technical field
The utility model belongs to fire-protection equipment technical field, is specifically related to anti-explosion exhaust fume valve actuating mechanism.
Background technique
When fire occurs, due to the smog meeting rapid spread that fire produces, can building smoke control system play a role, effective eliminating guarantees that people withdraw scene of fire rapidly, the life safety that the harmful gas intrusion human body preventing smog from producing jeopardizes people plays an important role, and various exhaust smoke valve is fully used in smoke control system for a long time.But it is not traditional exhaust smoke valve in use also exists certain defect, because actuator adopts metal shell, explosion-proof and high temperature resistant, easily deform under the high temperature of the scene of a fire, cause normally opening and closing, unstable properties.In addition traditional smoke exhaust port adopts temperature sense to drive smoke exhaust port to open, but when there is harmful gas leakage or indoor smog fills the air, do not have the phenomenon that temperature raises, traditional exhaust smoke valve would not be opened, and also can not automatically carry out smoke evacuation and change wind work.Because ventilation smoke exhaust is not prompt enough, cause difficulty not only to indoor personnel escape and also add difficulty to stand-by service.Therefore a kind of anti-explosion exhaust fume valve actuating mechanism is needed to solve the problems referred to above.
Model utility content
The utility model, for the deficiencies in the prior art, provides a kind of anti-explosion exhaust fume valve actuating mechanism.This anti-explosion exhaust fume valve actuating mechanism reliable performance, explosion-proof performance are good, long service life.
The technical solution of the utility model is achieved in that a kind of anti-explosion exhaust fume valve actuating mechanism comprises the explosion-proof casing be made up of refractory ceramics, described explosion-proof casing inside is provided with electromagnet, the hook that core connects is moved with this electromagnet, the reset tension spring of coupling hook, be contained in the ratchet engaged on pawl axis and with hook, sent sensitive switch and the control panel of signal by ratchet; Described explosion-proof casing outside is also provided with temperature fuse and smoke sensor; Described electromagnet, temperature fuse and smoke sensor are electrically connected with control panel respectively.
Preferably, described explosion-proof casing is also provided with for fixing mounting hole.
Preferably, described explosion-proof casing is also provided with many wiring terminals.
Preferably, described hook is connected to metal stay cord.
Preferably, described temperature fuse is 70 DEG C of marmem temperature sensors.
Preferably, described smoke sensor is ion type smog sensor.
The utility model solves the defect existed in background technique, has following beneficial effect:
The anti-explosion exhaust fume valve actuating mechanism reliable performance that the utility model provides, can issue out fire alarm in cigarette sense and warming, automatic opened smoke-discharging valve valve switch, and output action signal.Actuator is arranged in explosion-resistant enclosure, makes anti-explosion exhaust fume actuator have the performance of explosion-proof flame proof.There is volume little, safe and reliable, the features such as long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of anti-explosion exhaust fume valve actuating mechanism;
In figure: 1-explosion-proof casing, 2-reset tension spring, 3-electromagnet, 4-links up with, 5-stay cord, 6-ratchet, 7-sensitive switch, 8-temperature fuse, 9-smoke sensor, 10-control panel, 11-mounting hole, 12-wiring terminal.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of anti-explosion exhaust fume valve actuating mechanism as shown in Figure 1, comprise the explosion-proof casing 1 be made up of refractory ceramics, explosion-proof casing 1 inside is provided with electromagnet 3, the hook 4 that core connects is moved with this electromagnet 3, the reset tension spring 2 of coupling hook 4, be contained in the ratchet 6 engaged on pawl axis and with hook 4, sent sensitive switch 7 and the control panel 10 of signal by ratchet 6; Explosion-proof casing 1 outside is also provided with temperature fuse 8 and smoke sensor 9; Electromagnet 3, temperature fuse 8 and smoke sensor 9 are electrically connected with control panel 10 respectively.Explosion-proof casing 1 is also provided with for fixing mounting hole 11.Explosion-proof casing 1 is also provided with many wiring terminals 12.Hook 4 is connected to metal stay cord 5.Temperature fuse 8 is 70 DEG C of marmem temperature sensors.Smoke sensor 9 is ion type smog sensor.Refractory ceramics, has high temperature resistant, high strength, high hardness usually, good electrical property, thermal characteristics and chemical stability.In the high temperature of the scene of a fire, the explosion-proof casing of refractory ceramics can the device of available protecting actuator inside.There is good explosion-proof performance.
Working procedure of the present utility model is: when fire occurs, when temperature reaches 70 DEG C, temperature fuse 8 fuses and sends signal to control panel 10, or when in indoor air, smokescope exceedes established standards, smoke sensor 9 sends signal to control panel 10, and signal is sent to control centre by control panel 10.Control centre sends charged signal to this anti-explosion exhaust fume actuator, connect DC24V direct current to after control panel 10 receives signal electromagnet 3, the dynamic core action of electromagnet 3, hook 4 is pulled by connecting sheet, itself and ratchet 6 are thrown off, the exhaust smoke valve sharf connected with pawl axis can turn round rapidly under the effect of leaf spring, thus is opened by valve blade.In the rotation process of ratchet 6 after disengagement, can touch the compressing tablet contact of sensitive switch 7, make the electrical signal that sensitive switch 7 output valve is opened, sensitive switch is other fire-protection equipments of linkage also, implement self-extinguishing operation.The utility model also can carry out Non-follow control operation, namely pulls with hand stay cord 5, hook 4 and ratchet 6 are thrown off, by above-mentioned action step, opens exhaust smoke valve, or band triggers other fire-protection equipments.When resetting, can rotate counterclockwise pawl axis, make ratchet 6 return, engage with hook 4, namely valve is closed.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
