The utility model has the advantages that automatic timing closing of the gas, high personal and household safety, energy saving, high efficiency, time saving, convenience, wide range of application, convenient carrying and convenient popularization.
Description
Technical field: the utility model relates to the combustion gas regular automatical shutoff device that a kind of gas-fired boiler is used.
Background technique: at present, yet there are no in the stove and accessory that generally uses at home and have the gas-fired boiler of regularly closing gas combustion apparatus, people are when using gas-fired boiler, because it is careless and inadvertent, often dryout, pot is done, boil dry and the phenomenon of stewed dried foodstuff, and gas-fired boiler still is in the user mode that burns away, there is great potential safety hazard and wastes energy, as can not in time finding and handle, gently then cause easily because of waste fuel, food and valuable time and cause people's damage to property, this gives people's work, studying and living brings very big inconvenience and trouble, and is heavy then cause fire and casualty accident easily, serious harm people's safety of life and property.
Summary of the invention: the utility model mainly is to solve safety and problem of energy saving.The utility model is by housing 1, timer 2, normally closed gas valve 3, stirs connecting rod 4 and compressing tablet 5 etc. and partly constitute.Timer 2 is fixed on the position of keeping right in housing 1 front.Stir connecting rod 4 attachment hole 6, axis hole 7 and straight bending 8 are arranged, the attachment hole 6 of stirring connecting rod 4 interconnects by the spool attachment hole 10 on the spool 9 of bolt or latch and normally closed gas valve 3, the axis hole 7 of stirring connecting rod 4 is connected on the support 11 at housing 1 back side by bolt, and the other end of stirring connecting rod 4 then passes the T-slot 12 in housing 1 front and is stuck in the T-slot 12.Compressing tablet 5 with stir connecting rod 4 and be connected after, the position of compressing tablet 5 one ends is stretched near the rotating shaft 15 of timer 2, and can with latch 13 stacked contacts of rotating shaft 15.The other end of compressing tablet 5 then interconnects by spring 14 and the straight bending 8 of stirring connecting rod 4.
The beneficial effects of the utility model are: 1, can set cooking time, exceed set time, the automatic self-closing gas supply prevents from burning foods and has stopped to guarantee household and personal safety because of property heavy losses or personnel casualty accidents fire break out; 2, efficient energy-saving, time and labour saving, the convenient use not only can be increased economic efficiency but also can improve culinary art efficient and culinary art level; 3, applied widely, easy to carry, except that can directly be assemblied on the various gas-fired boilers or with the supporting use of various gas-fired boilers, also can be used as the valve control switch of various fluids such as other gases, liquid; 4, cost low, conveniently apply.

Among the figure: the 1st, housing, the 2nd, timer, the 3rd, normally closed gas valve, the 4th is stirred connecting rod, the 5th, compressing tablet, the 6th, attachment hole, the 7th, axis hole, the 8th, straight bending, the 9th, spool, the 10th, spool attachment hole, the 11st, support, the 12nd, T-slot, the 13rd, latch, the 14th, spring, the 15th, rotating shaft, the 16th, timer knob, the 17th, suction port, the 18th, air outlet, the 19th, inner spring.
Embodiment: the utility model will be further described below in conjunction with accompanying drawing:
Referring to Fig. 1～Fig. 4, normally closed gas valve 3 of the present utility model under normal circumstances is place's closed conditions, stir connecting rod 4 and then be in the left side in the T-slot 12 promptly on the position of " pass ", stirred to the right and promptly dialled on the position of " opening " when stirring connecting rod 4, and upwards beat to the position of " automatically " or when beating position to " manually " downwards, because under the effect of the restoring force of the inner spring 19 of normally closed gas valve 3, stir connecting rod 4 and can keep under the situation that does not have other external force effects on the position of original " automatically " or " manually ", at this moment normally closed gas valve 3 is in opening state.Be on the position of " automatically " if stir connecting rod 4, and after timer 2 begins countdown, the latch 13 of timer 2 in rotating shaft 15 is also along with rotating shaft 15 rotates counterclockwise, when the countdown concluded also multiple " 0 ", latch 13 with compressing tablet 5 to pressing down, and drive simultaneously and stir connecting rod 4 and move down, when stirring connecting rod 4 and moving to the horizontal position of T-slot 12, because the effect of the restoring force of the inner spring 19 of normally closed gas valve 3, stirring connecting rod 4 returns on the position of " pass " automatically, this moment, normally closed gas valve 3 was in closed condition, thereby reached the purpose that timing automatic is closed combustion gas.
When using the utility model, earlier source of the gas is inserted suction port 17, air outlet 18 is connected with the suction port of gas-fired boiler then, by the timer knob 16 that turns clockwise, timer 2 is set on the required timing, to stir connecting rod 4 again dials on the position of " automatically " in T-slot 12, at this moment, normally closed gas valve 3 is in opening state, gas-fired boiler can normally use, when timer 2 when the countdown concluded and when multiple " 0 ", stir connecting rod 4 and return automatically on the position of " pass " in the T-slot 12, normally closed gas valve 3 is in closed condition and combustion gas is closed at this moment, thereby reaches the purpose that timing automatic is closed combustion gas.When not needing automatic self-closing gas, as long as will stir connecting rod 4 dials on the position of " manually " in T-slot 12, normally closed gas valve 3 will present permanent opening state, can automatic self-closing gas, when needs are closed combustion gas, return on the position of " pass " in the T-slot 12 as long as will stir 4 groups on connecting rod with hand, normally closed gas valve 3 will be in closed condition, and the utility model will be closed combustion gas.The utility model except that can directly be assemblied on the various gas-fired boilers or with the supporting use of various gas-fired boilers, also can be used as the valve control switch of various fluids such as other gases, liquid.The utility model is closed the mode of combustion gas by timing automatic, both can reach safety, purpose of energy saving on the one hand, on the other hand again accurately cooking time, improve the culinary art level, the while is accomplished the purpose easily that saves time again.The utility model also can be installed barometer in air outlet 18, so that directly monitor combustion gas air pressure and take corresponding safety measure, further improve the Security of using gas-fired boiler.
