Abstract
The utility model relates to a multifunctional smoke emission valve which is suitable for the occasions of fire-fighting and smoke evacuation. The utility model essentially comprises a valve body, an electromagnet and a mobile hook. The bottom of the valve body is provided with a ratchet wheel, and a small gear at the middle of the ratchet shaft meshes with a big speed-down and distance-up gear at the middle of the valve body; a reset handle and a switch cam are positioned on the big speed-down and distance-up gear. The electromagnet is arranged on the upside of the valve body and the sucker of the electromagnet is connected with the mobile hook which is provided with manual control device. The right side of the valve body is provided with a reset pole to drive the closing of the valve through the rotation of the speed-down and distance-up gear which is positioned at the middle of the valve body on the one hand and to reach the aim of alarm through triggering an alarm device through a switch board on the other hand. Because of the mounting of the speed-down and distance-up gear, the utility model can decrease the starting current of the electromagnet greatly, reduce the mounting size of the valve body, prolong the service life of the valve gate and also enormously save the electric energy.
Description
Technical field: the utility model relates to a kind of fire-fighting, smoke evacuation product of being used for, and particularly relates to a kind of multi-functional exhaust smoke valve device.
Technical background: in hotel, dining room and tall building, a whole set of fire-protection equipment often can be installed all, several fire-fightings particularly be installed with preventing the exhaust smoke valve device.In case when breaking out of fire, can make ventilation equipment be in closed condition by temperature control or circuit control, report to the police simultaneously, make fire loss drop to bottom line.In actual use, because valve and blade are the rigidity material, when throttle down, sharp impacts can take place, also can deform when serious, shortened the operating life of valve and blade; Particularly when opening and closing, the weight of valve is heavier, and the electromagnet power demand is often very big during unlatching.Like this, need expend a large amount of energy on the one hand, electromagnet must be done very greatly on the other hand, and the required volume that accounts for is also more, is unfavorable for the installation and the debugging of equipment.
Summary of the invention: the purpose of this utility model will provide a kind of multi-functional exhaust smoke valve device exactly, and it can solve the existing defective of above product well.The purpose of this utility model is to realize like this, a kind of multi-functional anti-exhaust smoke valve device is made up of valve body, electromagnet, reseting handle, manual overvide, it is characterized in that: be provided with ratchet in described valve body bottom, the axle central authorities of ratchet are equipped with small gear, and described small gear increases the square gearwheel with the deceleration that is arranged on the valve body middle part and is meshed; Increase in deceleration and to be separately installed with reseting handle and switch cam on the square gearwheel; Electromagnet is installed in the top of valve body, and an end of Removable hook is connected with the suction nozzle of electromagnet, and the other end is stuck on the ratchet by the head of Removable hook, also is provided with manual overvide at the head of described Removable hook; Be provided with switch plate and warning device in the left side of valve body; Right side at valve body is provided with release link, and an end of described release link is fixed on the rivet at valve body middle part by the release link torsion spring, and the other end is stuck on the meltable bar.The utility model increases the power that the square gear can reduce the pulling valve closing effectively by the deceleration that is arranged on the valve body middle part, thereby can reduce the impact force of valve and blade, has prolonged the working life of valve.
Description of drawings: Fig. 1 is a structural representation of the present utility model
1. valve body, 2. electromagnet, 3. reseting handle, 4. manual overvide, 5. rivet, 6. ratchet, 7. angle indicator 8. slows down and increases square gearwheel, 9. switch cam, 10. switch plate, 11. warning device, 12. small gears, 13. Removable hooks, 14. release links, 15. release link torsion springs.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
In the drawings, a kind of multi-functional anti-exhaust smoke valve device of the utility model is made up of valve body 1, electromagnet 2, reseting handle 3, manual overvide 4, it is characterized in that: be provided with ratchet 6 in described valve body 1 bottom, the axle central authorities of ratchet 6 are equipped with small gear 12, and described small gear 12 increases square gearwheel 8 with the deceleration that is arranged on valve body 1 middle part and is meshed; Increase in deceleration and to be separately installed with reseting handle 3 and switch cam 9 on the square gearwheel 8; Electromagnet 2 is installed in the top of valve body 1, and an end of Removable hook 13 is connected with the suction nozzle of electromagnet 2, and the other end is stuck on the ratchet 6 by the head of Removable hook 13, also is provided with manual overvide 4 at the head of described Removable hook 13; Be provided with switch plate 10 and warning device 11 in the left side of valve body 1; Be provided with release link 14 on the right side of valve body 1, an end of described release link 14 is fixed on the rivet 5 at valve body 1 middle part by release link torsion spring 15, and the other end is stuck on the meltable bar.During concrete enforcement, the utility model can come closing of control valve by two kinds of modes, the one, automatically controlled, when fire takes place, the cigarette sense and the temp-sensing device that are arranged in the ventilation duct can send fire alarm, control centre connects the DC24V electric current automatically, the electromagnet energising, after the adhesive, Removable hook breaks away from ratchet, and ratchet drives small gear and does the clockwise direction rotation under the effect of spring, and the rotation of small gear drives deceleration and increases the square gearwheel and counterclockwise rotate, the rotation drive switch cam disposed thereon that increases the square gearwheel of slowing down also is rotated counterclockwise, be connected with warning device thereby touch switch plate, output valve is shutdown signal, increases the square gearwheel in rotation and slow down, drive valve and also rotate, thus throttle down.The 2nd, temperature control, when if the gas flow temperature in the pipeline reaches 70 ℃-280 ℃, at this moment, the easy appearance bar that is arranged on the valve body left side will be fused, and release link is under the effect of reset tension spring, hit an end of Removable hook rapidly, make the other end of Removable hook break away from ratchet, ratchet turns clockwise, and the drive deceleration increases the square gearwheel and counterclockwise rotates, thereby throttle down stops the continuation of fire to take place.The utility model can reduce the power of cut-off valve greatly owing to adopted deceleration to increase the square gearwheel, and required DC24V operating current has dwindled the volume of electromagnet less than 0.3A, and the installation dimension of valve body is diminished, and has also saved the energy simultaneously.
