Description
The utility model relates to a kind of valve that is used for gas kitchen ranges and can closes automatically when accident is flame-out.
Gas kitchen ranges is an indispensable apparatus in the daily life, valve wherein is from initial switch valve automatic lighting valve finally, its structure is constantly improved again, development along with growth in the living standard and technology, occurred the valve that when accident is flame-out, can close automatically in recent years, on the basis of original general gas kitchen range valve, increased the execution unit of flame-out signal generating part of a cover combustion gas and automatic-closing valve, like this when gas kitchen ranges normally uses, in case the flame-out gas that makes is overflowed, can send an actuating signal after several seconds approximately after then end flue temperature descends, and cut off source of the gas automatically by execution unit and stop working; Wherein the flame-out signal generation apparatus of combustion gas generally adopts temperature-sensitive element as sensor; with what adopt thermocouple is many; execution unit then generally adopts the magnetic control valve that is made of solenoid valve seat and magnetic valve; when kitchen range normally use; the voltage that thermocouple produced makes magnetic valve stay open state; combustion gas at first enters solenoid valve seat from the main valve air inlet pipe; solenoid valve seat then is communicated with the escape pipe of main valve; the combustion gas of coming out from escape pipe is at last burnt at burner; when accident extinguishing, the thermoelectric voltage on the thermocouple disappears, so magnetic valve cuts out under the effect of its resetting-mechanism; thereby cut off the approach that combustion gas enters main valve, reach the purpose of safeguard protection.Yet in existing this valve, its solenoid valve seat is positioned under the main valve mostly, causes the valve overall length long, is difficult to use in ultrathin gas kitchen ranges and the built-in type cooker.
The purpose of this utility model provides a kind of solenoid valve seat to be positioned at the gas stove valve of the band protector of accident extinguishing of main valve one side with regard to being at above-mentioned prior art present situation.
Design of the present utility model is: the gas stove valve of band protector of accident extinguishing comprises main valve and magnetic control valve; main valve is provided with gas inlet pipe and escape pipe; the air inlet pipe of main valve links to each other with source of the gas; the burner of escape pipe gas kitchen ranges links to each other; it is characterized in that described magnetic control valve comprises solenoid valve seat and magnetic valve; be positioned at a side of main valve; and the inlet chamber of main valve; outlet chamber respectively with the outlet chamber of the solenoid valve seat of magnetic control valve; inlet chamber links to each other; the outlet chamber of solenoid valve seat links to each other with inlet chamber and is L-shaped; in the inlet chamber of solenoid valve seat, accommodate the piston of magnetic valve; this piston can be blocked interface channel between inlet chamber and the outlet chamber; in the outlet chamber of solenoid valve seat, then be provided with the push rod that oblique " L " type top flat and that has reduction torsion spring has back-moving spring; the top of top flat also can be rotated around bearing pin by a bearing pin is fixing; the head of push rod stretches out outside the solenoid valve seat and can be depressed by pressure part once; afterbody then pushes up mutually with the middle part of top flat; when push rod promotes " L " type top flat when rotate on its top, the afterbody of top flat promptly passes outlet chamber and enters inlet chamber.
Two pairs of gas passages between described magnetic control valve and the main valve are connected on the interface of sidepiece separately and are provided with between the two around the sealing ring around these two pairs of gas passage mouths
The piston of the magnetic valve that is held in the inlet chamber of described magnetic control valve is supported by a back-moving spring, and the head of piston is provided with sealing gasket, and afterbody then stretches in the magnetic coil.
The described parts that press down of depressing the push rod of magnetic control valve are gland or the special pressing plate that can depress the ignition mechanism switch simultaneously that fixes with rotary knob rod.
Compared with prior art, the utility model is arranged on a side of main valve with solenoid valve seat, and well-connected transmission mechanism is arranged on valve inner, thereby not only the length of whole valve body is no more than the length of main valve, and the switch motion flexibility and reliability of valve, applicable to embedded gas kitchen ranges.
