Description
Technical field
The utility model relates to gas burning roastor, particularly relates to a kind of burnt gas valve controller of gas burning roastor.
Background technology
The opening and closing of the Control burnt gas valve of the Gas controller employing of existing gas burning roastor, because its volume ratio of relay is comparatively large, need larger installing space, the cost of relay is also higher, due to relay ceaselessly folding in the formation used, cause the life-span shorter.Gas burning roastor needs to change Gas controller after the limited number of times of use.
Summary of the invention
The purpose of this utility model is the deficiency existed for prior art, provides that a kind of volume is little, the burnt gas valve controller of the gas burning roastor of the low long service life of cost.
For achieving the above object, the technical scheme that the burnt gas valve controller of the utility model gas burning roastor adopts is:
A kind of burnt gas valve controller of gas burning roastor, comprise the first controllable silicon, voltage-stabiliser tube, electric capacity and the second controllable silicon, the first described silicon controlled emitter stage is in series with the negative pole of voltage-stabiliser tube and the positive pole of electric capacity, be connected with the colelctor electrode of the first triode between the negative pole of voltage-stabiliser tube and the positive pole of electric capacity, the base stage of the first triode is connected with one end of the first resistance, the emitter stage of the first triode is connected with the other end of the first resistance by the second resistance, the link ground connection of the first resistance and the second resistance, the base stage of the first triode is also connected with the 3rd resistance, the other end of the 3rd resistance and single-chip microcomputer, the colelctor electrode of the first triode is also in series with the 4th resistance, 4th resistance and the 5th resistance, control pole with the second silicon controlled after one end connection of the 6th resistance to be connected, second silicon controlled anode is connected with gas valve coil one end, second silicon controlled negative electrode is connected with power cathode, the other end of the 5th resistance is connected with single-chip microcomputer, the other end ground connection of the 6th resistance, the positive pole of voltage-stabiliser tube and the minus earth of electric capacity, first silicon controlled base stage is connected with one end of the 7th resistance, the other end of the 7th resistance and single-chip microcomputer, first silicon controlled colelctor electrode is connected with positive source.
The utility model compared with prior art, has the following advantages:
The ion-conductance that burnt gas valve is mainly produced by flame maintain conducting, replace original relay to make control original paper with controllable silicon, silicon controlled driving power is very little, than relay longer many on service life.General relay is 100,000 actions, but controllable silicon can reach about 1,000,000 times.Because controllable silicon driving power is smaller, so just can select little a lot of electric capacity, also save cost like this.Silicon controlled small volume, cost is lower, and service life is longer, effectively decreases burnt gas valve controller installing space, reduces manufacturing cost, extend the service life of burnt gas valve controller.
Accompanying drawing explanation
