Abstract
The utility model discloses a double-coil electromagnetic value. A pair of magnetic cores that pull in the block are arranged in the shell of the electromagnetic value, the spring is arranged between the block and the shell, the main coil and the auxiliary coil are winded on the magnetic cores respectively. One end of the main coil is connected with the thermocouple, and the other end is connected with the shell. The both end of the auxiliary coil is connected with the output of the controller that can supply forward current and backward current to the auxiliary coil. The double-coil electromagnetic value is applied in the safety protection device of the gas-fired instrument, the separated auxiliary coil can realize separately control to prevent other signals to interfere the main coil, thereby avoid misoperation and increase the security. The utility model is input current only when ignition or extinguish accidentally, but when working, the electromagnetic value is pull in by current generated by heating thermocouple, so consumes less power.
Description
Technical field
The utility model relates to the electromagnetic valve structure that is applied in the Gas Utensil Lighting safety protection device, especially the solenoid valve of two coil configuration.
Background technique
In the Gas Utensil Lighting safety protection device, the combination of widespread usage thermocouple and solenoid valve reaches the blowout protection purpose.The solenoid valve that for example is applied in the wink heat absorption galvanic couple formula flame-out protection device is exactly the dual coil electromagnetic valve; two statures of its main coil and ancillary coil link to each other with pulse igniter with thermocouple respectively; and two statures all connect shell in addition; be equivalent to link together, when pulse igniter during, can interfere like this another group main coil to the ancillary coil input signal; be prone to misoperation; just in case ancillary coil breaks down, main coil will be influenced by it, so safety in utilization is relatively poor.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and provides a kind of ancillary coil independent, by two separately controllable dual coil electromagnetic valves of termination contact.
Technical problem of the present utility model is achieved through the following technical solutions: the dual coil electromagnetic valve that is applied in the Gas Utensil Lighting safety protection device; be provided with the magnetic core of a pair of energising adhesive chock in this electromagnetism valve housing; be provided with spring between chock and housing; twining main coil and ancillary coil on a pair of magnetic core respectively; one termination thermocouple of main coil; the other end body contact body, the two ends that it is characterized in that described ancillary coil are connected to and can provide on two output terminals of controller of forward current and back current to it by lead.
Compared with prior art; the utility model has changed the Placement of ancillary coil in the dual coil electromagnetic valve; make ancillary coil independent; can control separately by two termination contact; prevent of the interference of other electrical signal to main coil; thereby avoid occurring the misoperation phenomenon; improve Security; it is applied in the Gas Utensil Lighting safety protection device; be to dual coil electromagnetic valve input current when igniting or during accident extinguishing only; and be the electric current adhesive solenoid valve that heating produces by thermocouple in the working procedure, so power consumption is less.
Description of drawings
Fig. 1 has provided the utility model structural representation.
Embodiment
By above-mentioned accompanying drawing embodiment the utility model is described in detail again.
As shown in Figure 1; the dual coil electromagnetic valve; especially be applied in the dual coil electromagnetic valve in the Gas Utensil Lighting safety protection device; in its housing 1, be provided with a pair of magnetic core 3; twining main coil 6 and ancillary coil 2 on the magnetic core respectively; and by the chock 5 of the rubber system of magnetic core adhesive; 1 of chock 5 and housing are provided with spring 4; main coil 6 one termination thermocouple I; the other end body contact body 1; utilize the thermocouple reliable operation; characteristics such as durable power saving; but thermocouple itself has inertia again; defective such as slow in reacting; be to solve the defective of thermocouple, matching design intelligent controller II is connected to the controller II (design in addition that forward current and back current can be provided to it with the two ends of the ancillary coil 2 of dual coil electromagnetic valve by lead; do not belong to this case content) two output terminals on, make thermocouple I more perfect in the working state of the blowout protection that is used for gas range.
The working procedure of dual coil electromagnetic valve is:
1. after controller II connected switch, ancillary coil 2 must have forward current to pass through, and solenoid valve moment is boosted by the conducting of controller electronic component by adhesive, for the kitchen range igniting.
2. do not lighted as kitchen range, solenoid valve ancillary coil 2 no forward currents pass through, and solenoid valve is turned off under spring 4 effects, and igniting stops.
3. after kitchen range were lighted, solenoid valve ancillary coil 2 no back currents passed through, and did not influence the normal adhesive of solenoid valve (because of thermocouple I is produced voltage by the normal adhesive of solenoid valve main coil 6 quilts by flame burning heat back) this moment.
4. when the flame accident is extinguished, because inductive needle is visited less than fire, by the conducting of controller II electronic component, make solenoid valve that a back current be arranged, the forward current that this back current is produced much larger than thermocouple I normal combustion, the positive and negative solenoid valve that offsets is turned off under spring 4 effects immediately.
