Abstract
The utility model relates to a safety electromagnetic valve for flameout protecting for a gas range, which is instantly opened and instantly closed, and gas switching is controlled. The utility model comprises a sealing gasket 1, a support cushion 2, a moving iron core 3, a spring 4, a coil 13, a skeleton 12 and a stationary iron core 16. An annular constant magnet 10 and an annular steel gasket 11 are sheathed on the moving iron core 3. The utility model has the advantages that a valve can be immediately opened to ignite and can be immediately closed to extinguish, manufacture is easy, cost is low, etc.
Description
The utility model belongs to the safety valve that is used for switch and protective effect on a kind of safety valve of controlling the combustion gas break-make, the especially gas kitchen ranges.
At present, existing gas kitchen ranges safety valve is by the work of thermocouple control magnetic valve.This magnetic valve is made up of valve rod, seal gasket, pad, spring, armature, coil, skeleton, U sections core, this gas electromagnetic valve is when driving valve, flame must heat thermocouple, it is enough big to treat that its thermoelectrical potential output rises to, and make the coil current on the magnetic valve U sections core also enough big, the magnetic force that U sections core produces can suck armature, and the user just can let go.Therefore can not drive valve immediately, operating handle is poor.And when flame-out, the hot thermocouple electromotive force reduces gradually, and coil current also slowly reduces thereupon, arrives to a certain degree when electric current is little, and the electromagnetic force of generation can not be kept and suck armature, and armature resets, and fuel gas path is cut off.This process combustion gas is overflowed in a large number, thereby safety protection function is not good.And this magnetic valve requires height, shortcomings such as product is poor to the inferior fuel gas tolerance, unstable properties to the material and the processing precise degree of its internals.
The purpose of this utility model provides a kind ofly can be opened valve point fire immediately and close the flame-out gas kitchen ranges blowout protection security solenoid valve of valve immediately.
For achieving the above object; technical scheme provided by the utility model is: a kind of gas kitchen ranges blowout protection security solenoid valve; it comprises seal gasket; pad; moving iron core; spring; coil; skeleton; static iron core; seal gasket and pad are installed in an end of moving iron core; on seal gasket and the pad spring is housed; the other end of moving iron core is provided with static iron core; coil and skeleton; be with the permanent magnet of annular and an annular steel packing ring on the moving iron core; static iron core; permanent magnet of annular and annular steel packing ring are contained in the U type support; a valve seat is adorned in the one end riveting of U type support, and the other end is installed a shrouding.
Compared with prior art, because the utility model adopts permanent magnet, the magnetic field force of its generation can attract moving iron core firmly, therefore can keep valve opening and igniting when driving valve immediately.Because the electromagnetic force that produces during coil electricity of the present utility model can be offset the intrinsic magnetic field of permanent magnet immediately, when therefore closing valve, valve can be closed and stop working immediately again.This blowout protection safety device realized when the burner accident extinguishing, can the insantaneous break fuel gas source, thereby safety protection function is very good.Simultaneously, the utility model is strong to the tolerance of inferior fuel gas, and processing and manufacturing is easy.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model gas kitchen ranges blowout protection security solenoid valve.
Fig. 2 is the working state schematic representation of the utility model gas kitchen ranges blowout protection security solenoid valve.
The utility model gas kitchen ranges blowout protection security solenoid valve shown in Figure 1; by seal gasket 1; pad 2; moving iron core 3; spring 4; coil 13; skeleton; static iron core 16 formations such as grade; seal gasket 1 and pad 2 are installed in an end of moving iron core 3; on seal gasket 1 and the pad 2 spring 4 is housed; the other end of moving iron core 3 is provided with static iron core 16; coil 13 and skeleton 12; be with the permanent magnet 10 of annular and an annular steel packing ring 11 on the moving iron core 3; static iron core 3 annular permanent magnet 10 and annular steel packing ring 11 are contained in the U type support 14; a valve seat 8 is adorned in the 14 1 end rivetings of U type support, and a shrouding 18 is adorned in other end riveting.Static iron core 16 rivetings are contained on the shrouding 18.Be provided with coil 13 in coil rack 12 wire casings, two lead-out wire directly passes the end plate of skeleton 12 and shrouding 18 and draws.
Also be with a cylindrical sleeve 6 on described moving iron core 3 and the static iron core 16, be used for the location of moving iron core 3 and static iron core 16.
Also be with a plastic sheath 5 on the described valve seat 8, be provided with an O-ring seal 7 between plastic sheath 5 and the valve seat 8, be used to prevent that combustion gas from entering valve inside.O-ring seal 7 with valve seat 8 end faces is realized sealing with its jam-packed at plastic sheath 5 by the tension force of spring 4, and this design by spring tension realization self hermetic seal its objective is for the ease of assembling and maintenance.
Also be provided with a sealing ring 9 on the described valve seat 8 in addition, be used to prevent that gas leakage from going out valve body 21.
Also be provided with a cushion rubber 15 on the described static iron core 16, establish packing ring 17 between skeleton 12 and the shrouding and be used to prevent that combustion gas from leaking outside.
In the working state schematic representation of gas kitchen ranges blowout protection security solenoid valve shown in Figure 1 and gas kitchen ranges blowout protection security solenoid valve shown in Figure 2; have air admission hole 23 and venthole 22 on the gas valve body 21; when driving valve; push rod 20 will move iron core 3 and push static iron core 16 to; the magnetic field force that the permanent magnet 10 of annular produces will move iron core 3 and firmly hold; the user can loose one's grip, and push rod 20 resets, and valve also can be held open state.At this moment, with the electronic controller 25 that gas kitchen ranges blowout protection security solenoid valve 24 is connected, export high-voltage pulse simultaneously, the igniting pin 30 that order is connected with electronic controller 25 discharges electric spark to stone or metal plate for standing a stove on as a precaution against fire 29 and lights combustion gas generation flame 28.Electronic controller 25 provides electric energy by power supply 26.When stopping working when meeting accident; the probe 27 that is connected with electronic controller 25; detection is flowed less than ion; electronic controller 25 passes through lead 19 immediately to the 24 output order pulses of gas kitchen ranges blowout protection security solenoid valve; coil 13 produces a direction and the opposite electromagnetic field of permanent magnet 10 intrinsic magnetic fields, makes 16 of iron core 3 and static iron cores lose suction, and spring 4 will move iron core 3 and push venthole 22 to; valve closing, burner have been realized flame-out safety protection function.
