Abstract
The utility model discloses a timing closing-apparatus for coal gas valves, which is composed of an interval timer 4 arranged on the proper part of a housing 15, an air valve rotary shaft 5, a crank 3, and a master gear 7 and a position baffle plate 6 which are arranged on the rotary shaft. The utility model can adopt the manual control and the timing self-closing control two ways, and the timing self closing is realized through the mating reaction of gearwheels, the rotary shaft, the crank and springs under the timing control. A U-shaped cuff is arranged at the lower part of the rotary shaft 5 to jam the existing gas stop turn knob, and then the two control ways can be realized. The utility model, which has the advantages of simple and reasonable structural design, flexible and convenient use, is energy-saving and safe, and is suitable for domestic gas ranges to use in particular.
Description
The utility model relates to a kind of gas stove timing of valve self closing device, and this device is assembled by mechanical timer and air valve mechanism for opening/closing two parts.
The air valve of existing all kinds of gas range or liquefied gas cooker; the most needs with its keying of hand control and adjustment fire combustion size; because air valve can not timing automaticly be closed; using in the gas-cooker process to run into through regular meeting closes untimely or because the pass gas check valve is forgotten in negligence because of air valve; the fuel gas that is caused is wasted in a large number; the used utensils of scaling loss boiling etc. sometimes even cause fire to take place, bring unnecessary trouble and loss for people's daily life.
In order to prevent above-mentioned similar thing, in the last few years, people's several timing of valve shutoff devices that released one after another, the pipeline of introducing as Chinese patent CN85205613 is mechanical closure mechanism regularly; The disclosed mechanical type timing of valve of CN86203534 shutoff device all is to adopt timer control air valve to cut out automatically at the fixed time.Above-mentioned two patents respectively have certain features on its structural design, but there are some common problems simultaneously, promptly in former manual air valve rotating shaft, be provided with the lever transmission mechanism that ratchet and pawl is formed, fire by after turning down greatly the adjustment of fire combustion size is particularly fiery, because the ratchet effect makes the fiery combustion can't be big by ditty again, use certain problem of bringing to the resident, moreover, above-mentioned two kinds of structures can't be used with former manual air valve, must change former air valve could use, and also has certain problem in installation and economic aspect.In addition, the mechanism driving structure setting of introducing in the CN85205613 patent is comparatively complicated.
The purpose of this utility model all is to overcome the deficiency of above-mentioned prior art and provides a kind of simple in structure, flexible and convenient to use, can the manual or timing automatic regularly closer of dual-purpose gas valve of closing.
Now with the characteristics of the utility model structure, conjunction with figs. is described below:
Fig. 1 is the utility model agent structure schematic diagram.
Fig. 2 is the utility model transmission mechanism schematic diagram.
Basic structure of the present utility model is to close transmission mechanism by timer 4 that is arranged on housing 15 suitable positions and air valve to be assembled, and it is characterized in that:
B, be equipped with and recessedly take turns 11 and the timer of thimble 10 frame for movements, being used for timing controlled air valve 1 in time closes, when not using timer 4, thimble 10 is by master gear 7 or drive 8,9 disengagings in the middle of it in its action of reset spring and the transmission mechanism, is in recessed the wheel in 11 the recess; Be rotated counterclockwise timer 4 and provide the top value of fixing time, thimble 10 and leave recessed 11 the recess position engagement of taking turns, pin said gear 7,8,9.
Below this closer of brief description operation principle helps the reader further to understand its structure.
This closer is installed on the air valve position, rotates counterclockwise crank 3 and make spring 12 be in relaxed state, get final product any turn-knob air valve, adjust fire combustion size, be manual control at this moment and use.Regularly use this closer as needs, then at first open the air valve 1 and adjustment of fire combustion size is suitable, clockwise again turn-knob timer 4, one scheduled time value is set, thimble 10 left the recessed recess of taking turns and withstood on to gear 7 or idler gear 8,9 and with its pinning this moment, stir crank 3 at last clockwise to limited post 13 positions, back-moving spring 12 makes master gear produce a clockwise moment.After timer reaches scheduled time value, recessed home position of taking turns 11 recoveries, thimble 10 breaks away from gear and returns in the recess under its action of reset spring, this moment turning cylinder 5 and master gear 7 drive air valve 1 under spring 12 effects is in time closed automatically, and this kind sight is that self-closing control is used.
By the above as can be seen, air valve is closed reliably automatically rapidly, spring 12 plays an important role.Elastic force is excessive, stirs crank 3 efforts and is awkward; Elastic force is too small, it is unfavorable that air valve is in time closed, and therefore needs to select as the case may be suitable spring.Also should consider rigging position between master gear 7 and the crank 3 in addition, under overall structure was tried one's best compact prerequisite, crank 3 radiuses of gyration were big as far as possible.Positioning baffle 6 is used to limit the air valve closed position.
This closer not only can be set directly on the new gaspipe line, as gas control valve, and can be arranged on the existing gaspipe line, control former air valve knob with it, specifically above-mentioned air valve 1 can be changed into a U type air valve knob pullover (referring to Fig. 1), this U jacket head is assemblied on turning cylinder 5 lower end positions, is used to block former air valve knob, need not change former air valve like this and can satisfy air valve and close needs automatically.Fix the used connector of this closer and be arranged on housing 15 suitable positions.Be used for fixing on pipeline.
This closer is not only simple and compact for structure, volume is little, cost is low, use is flexible, easy for installation, the more important thing is and realized manual and timer cuts out two combinations automatically.The utility model is fit to the family gas kitchen range and liquefied gas cooker uses, and certainly, does not get rid of other occasion and liquid fluid here and uses.Use this closer in time to close gas check valve, accomplish safe and reliable, save the energy, try to gain time precious to one for people.
Claims (2)
1, a kind of gas valve closer regularly, its basic structure comprise that the timer (4) that is arranged on housing (15) suitable position and air valve close transmission mechanism and form of the present utility model being characterised in that:
A, air valve turning cylinder 5 fixedly are equipped with master gear (7) and positioning baffle (6) thereof, spring (12) two ends are separately fixed on baffle plate (6) and the crank (3), crank (3) rotates around it center (14) tension or loose spring (12), and the maximum rotation scope is limited by limited post (13)
