Abstract
The utility model discloses an automatic cut-off device for unexpected gas-flameout. The utility model is characterized in that an on-off valve, which is connected with a spring and a bolt, is arranged inside a closed type crust; a steel ball at the upper end of the on-off valve is connected with a manual switch; the sides of the steel ball and the manual switch are connected with an automatic push rod whose tail end is connected with a corrugated pipe which is provided with a heat-conducting needle and is filled with liquid; both sides of the top of the crust are respectively provided with clamp spring assemblies; the left side of the crust is provided with a jet nozzle, and the right side of the crust is provided with a gas-supply drum. The utility model has the advantages of low cost, small size, reliable mechanical-property, strong permanence, safety, economy, practicality, easy installation and replacement, etc.
Description
The utility model relates to a kind of stove and accessory accessory, particularly a kind of combustible gas accident extinguishing safety shutoff.
At present, China cooks, heats up water is the energy with various fuel gas all, excessively when excessive or kettle water is held when pot for cooking rice all burning things which may cause a fire disaster can be put out.Combustible gas can leak automatically like this, causes fire or people's combustion gas is poisoned.
The purpose of this utility model provides a kind of for preventing pot for cooking rice, extinguishing the combustible gas accident extinguishing safety shutoff of combustion gas when kettle is excessive.
The purpose of this utility model is achieved in that it comprises housing, open and close valve, bellows, the heat conduction pin, push rod, hand switch, nozzle, award inflator, windscreen, it is characterized in that: housing divides two parts, the keying valve is housed in closed shell, there is a spring bottom that opens and closes valve, spring directly is connected with bolt, there is steel ball the upper end that opens and closes valve, steel ball connects hand switch, the side of steel ball and hand switch is connected automatic switch push rod (being wound with return spring on the push rod), the tail end of automatic switch push rod connects one and has heat conduction pin and the bellows that liquid is housed, both sides, top at upper shell are equipped with the jump ring assembly respectively, nozzle is housed respectively and awards inflator at the left and right sides of lower house side, windscreen is housed on nozzle, and last lower house is affixed by bolt.
The utility model has the advantages that: mechanicalness is reliable, and permanent strong, safe, economic, practical, cost is low, and volume is little, easily changes, and easily installs.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a structure chart of the present utility model.
By accompanying drawing as can be known, housing is two parts about in the of 2 minutes, upper shell and lower house are affixed by bolt 14, in housing, be equipped with and open and close valve 1, spring 8 is equipped with in the bottom that opens and closes valve, spring 8 is connected with adjustment bolt 18, with sealing gasket 17 sealings, there is a steel ball 15 upper end that opens and closes valve, steel ball 15 links to each other with hand switch 7, the side of steel ball and hand switch is connected automatic switch push rod 10, is wound with return spring on the push rod, and the tail end of automatic switch push rod connects a bellows 4, liquid and heat conduction pin 5 are installed in bellows, both sides, top at upper shell are equipped with jump ring assembly 6 respectively, are not equipped with the left and right sides of lower house side part and award inflator 11 and nozzle 12, and a windscreen 13 is housed on nozzle 12.
Operation principle is: when pressing hand switch, descending the forcing in the compression of keying valve of hand switch pushes away the descending airway of opening of spring, and the breach of hand switch puts in place and blocked by the steel ball before the jump ring at this moment, makes gas unimpeded.After the fire heating that the heat conduction pin is lighted, rapidly thermal signal is delivered to bellows, bellows inner sealing heated liquid expands rapidly, make bellows extend promotion automatic switch push rod and get into hand switch and open and close the valve junction, force hand switch up, make the jump ring withdrawal.Thereby automatic switch occupies the position of hand switch.When accident extinguishing, stop the supple of gas or steam or close flammable air valve after because air turns cold, the bellows contraction of suffering from cold, automatic switch is return with bellows under the effect of spring, meanwhile, push away trapezoidal keying valve on " on push away spring ", make that to open and close valve up until the sealing blast tube.
Using method: hand switch is pressed, heard that click is opened airway, promptly will light a fire.In the igniting back short time, hand switch can be upspring automatically, and can hear the sound of click.Coal gas is normally closed, the very fast return of hand switch.
