Description

Gas self-control safety device

The utility model relates to a kind of combustion gas self-control safety device, is applicable to the safety auto-controlled of oil liquefied gas kitchen range and piped gas kitchen range.

At present the security control of combustion gas is had the control device of pure electronics, but poor reliability, the cost height as in short of electricity or the frequent place that has a power failure, then can not normally use this device.

It is a kind of easy to use that the purpose of this utility model is to provide, and the combustion gas self-control safety device of air intake valve is closed in the equal energy automatic control when gas leakage and operate as normal of reliable operation.

The technical scheme that realizes the utility model purpose is: Handle axis 5 is arranged in the lining in framework 6 holes, be fixed with pinion 4 on the axle, recessedly take turns 10 and the driving shaft of timer 11, recessed take turns 10 and pinion 4 between stage clip 7 is arranged, gear wheel 1 is arranged in the hole of framework 6, groove 1a is radially arranged at its top, regularly the right-hand member of connecting plate 8 has roller 8a, left end has roller 8b, regularly the axle of connecting plate 8 is fixed on the framework 6, have an end of 9, two extension springs 2 of torsion spring to be fixed on the gear wheel 1 on the axle, the other end is individually fixed on two screws of framework 6, free groove on the panel of shell 3, timer 11 is fixed on the cover plate 12 that is connected with framework 6, and the rotating shaft of electromagnet 15 and electromagnetism pin 16 is fixed on the gear wheel 1 and the piped gas coupling part is that fixing card 13 and bolt 14 are formed.

Fig. 1 is the structure front view that is used for piped gas of the present utility model, and Fig. 2 is the vertical view of Fig. 1, and Fig. 3 is the structure front view that the utility model is used for oil liquefied gas, and Fig. 4 is the vertical view of Fig. 3.

In conjunction with the accompanying drawings structure of the present utility model and embodiment are described as follows:

The utility model is mainly by canine tooth 1, extension spring 2, shell 3, pinion 4, Handle axis 5, framework 6, stage clip 7, regularly connecting plate 8, right roller 8a, left wheel 8b, torsion spring 9 recessedly takes turns 10, timer 11, cover plate 12, fixing card 13, bolt 14, electromagnet 15, electromagnetism pin 16, hook 16a, pinned torsional spring 17, spring arm-tie 18 is smelt quick pipe and infrared light emission pipe, and infrared receiver is formed.Press the Handle axis 5 that is arranged in framework 6 hole neck bush, and rotate counterclockwise Handle axis 5, the pinion 4 that is connected on it, recessed take turns 10 and the driving shaft of timer 11 also rotate thereupon, because after pressing Handle axis 5, pinion 4 is in the position of engagement with gear wheel 1, the gear wheel 1 that then is arranged in framework 6 holes is driven to clockwise rotate, and drive is arranged in the house lead in switch rotation of groove 1a and opens air intake valve gradually, axle is positioned at the timing connecting plate 8 on the framework 6, its left wheel 8b is owing to recessed the wheel turns over an angle counterclockwise and be pushed out groove, the power that goes up torsion spring 9 by axle is pressed in left wheel 8b on the recessed garden cylinder of taking turns, right roller 8a is the edge of close gear wheel 1 then, because the rotating shaft of electromagnet 15 and electromagnetism pin 16 is fixed on the gear wheel 1, when gear wheel 1 turns over 90 °, air intake valve is opened to amount big, the hook 16a of electromagnetism pin 16 just in time hooks right roller 8a simultaneously, in this section service life, user's use of can lighting a fire, behind the release handle axle 5, under the effect of stage clip 7 restoring forces, pinion 4 and gear wheel 1 are thrown off automatically, can the free adjustment time, counter clockwise direction is along 360 ° of time grooves that are carved with from 5～60 minutes on the panel of shell 3, one indication groove is arranged on handle, be fixed on the timer 11 on the cover plate 12 that is connected with framework 6, it is with timer backward rotation clockwise that recessed on its mandrel takes turns 10, after giving the time of putting, regularly the left wheel 8b on the connecting plate 8 enters in the recessed groove of taking turns, the hook 16a of right roller 8a and electromagnetism pin 16 throws off, because an end of two extension springs 2 is fixed on the spring arm-tie 18 of gear wheel 1, the other end is individually fixed on two screws of framework 6, when hook 16a throws off right roller 8a, the restoring force of two extension springs 2 is withdrawn into original position with gear wheel 1, drives air intake valve simultaneously and closes automatically.

When using piped gas, by the fixedly card 13 that is connected with cover plate 12, the groove 1a on bolt 14 and the gear wheel 1 links to each other the utility model with gas piping and house lead in switch; When using the oil liquefied gas bottle, earlier with the steel cylinder handwheel with protect frame and lay down, mandrel 21 is inserted on the former gas cylinder switch mandrel, adjust the position of upper chain wheel 20 according to the installation site with respect to following chain wheel, it is corresponding to make fixed support 22 and steel cylinder protect the screw hole of frame, uses screw-driving, former steel cylinder handwheel 23 is installed in upper end of the present utility model gets final product, do not change the structure of former piped gas and former steel cylinder, overall process of the present utility model is installed only needs 3～8 minutes.

In oil liquefied gas steel cylinder when inflation, as long as press down handwheel 23, make down chain wheel 19 and upper chain wheel 20 throw off rotation handwheels 23, just but freely openable inflate.

When combustion gas meets accident leakage, employing is smelt quick management and control system and is cut off source of the gas automatically, only need near cooking stove, to install one and smell quick pipe, when flame stops working owing to spilling water, strong wind etc. are unexpected, the coal gas that leaks makes to be smelt quick pipe and sends signal make the actuating of relay after amplifying, place the electromagnet 15 in the derailing switch to power on, the electromagnet core bar promotes electromagnetism pin 16, make hook 16a and regularly connecting plate 8 unhook on it, reach the purpose of automatic-closing valve, not enough as the gas concentration that leaks, after giving the time of putting, mechanical part is an automatic-closing valve, plays safety effect.

Utilize photosignal also can function as described above, two ends respectively are provided with an infrared light emission pipe and an infrared receiver on stone or metal plate for standing a stove on as a precaution against fire, open valve by handle 5, electro-delay system time-delay (delay time is adjustable), as in the time of setting, misfiring, there is not barrier between infrared light emission pipe and the receiver, send the signal of telecommunication, after amplifying, make work of electromagnet, valve-off.In setting-up time, light a fire, then do not have the signal of telecommunication and return feedback, can normally use.In case flame extinguishes suddenly, receiver is received the infrared ray signal, transfers the signal of telecommunication to, makes work of electromagnet, makes valve closing.

Advantage of the present utility model: 1. owing to adopt mechanical self-controlling safety device, reliable operation; 2. adopt machinery, smell quick or the photoelectric automatic control valve-off, in normal condition or accident extinguishing situation, all can automatic control close air intake valve, played the security insurance effect; 3. easy and simple to handle, easy for installation, save time; 4. because self-clocking, automatic valve-off has on time so just reduced combustion gas user of service's stress and labour intensity.
