Description
Technical field
This utility model relates to the electromagnetism automatic holding device of a kind of electromagnet core, specifically refers to for household gas range
The electromagnet core of electromagnetism plug valve, during igniting, it can be ensured that the one of electromagnet core reliable electromagnetism self-insurance makes electromagnet core
The device of reliable electromagnetism self-insurance.
Background technology
Electromagnet core be device in the valve body 01 of the electromagnetism plug valve of household gas range, be used for controlling domestic gas
The electromagnetic actuator device that the combustion gas gas circuit of stove opens and closes；The unlatching of electromagnet core is not directly driven by electric power, but
While being opened with plug valve by the push rod of electromagnetism plug valve, flap is pushed open downwards, therefore, household gas range
During igniting, the push rod of electromagnetism plug valve pushes down on the valve rod of electromagnetic valve core makes flap open, and combustion gas gas circuit connects
Logical, meanwhile, the dynamic iron core connected with valve rod contacts butt with static iron core downwards, is arranged on burner side
Thermocouple produces micro-electric current after being heated by the flame, form electromagnetic field through solenoid, make iron core and static iron core
Adhesive, and push rod upwards reset continue to afterwards keep adhesive, combustion gas gas circuit is held open state, combustion gas
Stove normal combustion；When household gas range meets accident extinguishing, thermocouple stops providing micro-electric current to solenoid,
Electromagnetic field disappears, and under the effect of back-moving spring, dynamic iron core, valve rod and flap upwards reset, and flap resets
Rear cut-out combustion gas gas circuit, ensures the safety of user with this.
The valve rod of prior art electromagnet core, flap and dynamic iron core are fixing to be connected as a single entity, refering to Fig. 9, due to
Micro-electric current that thermocouple is supplied to solenoid is the least, and this just requires to move iron core during igniting must essence with static iron core
Really reliable contacts butt, thus it requires described push rod, valve rod, the dimensional accuracy of dynamic iron core or accuracy of form and position palpus
Abnormal accurate；If the dimensional discrepancy of push rod exceeds standard, or the assembling shape position error of valve rod and dynamic iron core exceeds standard,
When actually used igniting, the butt that contacts of dynamic iron core and static iron core can be unreliable because above-mentioned deviation exceeds standard,
Micro-electric current is not enough to long distance through the electromagnetic force that solenoid produces and attracts the adhesive of dynamic iron core and static iron core, flap
I.e. upwards resetting with push rod, close combustion gas gas circuit, in other words, electromagnet core is opened by push rod effect, at push rod
When upwards resetting, it is impossible to enough rely on electromagnetic force adhesive self-insurance, occur combustion gas gas circuit be automatically switched off, gas-cooker without
The fault of method normal combustion；Additionally, in high-volume commercial production, for size, the shape position error of part
Require too high, production component, the cost of assembling goods can be made to occupy height, the problem of inefficiency；Therefore, existing
Unreliable with the presence of technology electromagnetism self-insurance, fault rate is high, cost is high, inefficient problems and shortcomings.
