Abstract
The utility model relates to a spark plug, comprising an outer shell, an annular holding bench arranged on the inner wall at an ignition place inside the outer shell, and a circular ring-shaped nickel pad welded on the annular holding bench. According to the utility model, the inner wall at the ignition place of the outer shell is provided with the annular holding bench and the annular holding bench is welded with the circular ring-shaped nickel pad which is characterized by oxidation-resistance and corrosion-resistance, so that the service life of the spark plug can be prolonged.
Description
Technical field
The utility model relates to a kind of gas engine part, relates in particular to a kind of spark plug.
Background technology
Spark ignition engine is by the air-fuel mixture in the spark ignitor combustion chamber.The performance of spark plug directly has influence on the performance of engine, if the indoor air-fuel mixture of ignition combustion that spark plug can not be correct, at least the fuel that has part in the combustion chamber can not burn, this will cause the loss of engine power, the increase of the reduction of oil inflame efficient and hydrocarbon discharge capacity.
The environment of spark plug work is exceedingly odious, needs igniting under the high-temperature and high-pressure conditions many times in the combustion chamber, and the deterioration of spark plug is unavoidable, deposit occurs on the present sparking-plug electrode of multilist, and causes the corrosion of electrode.
The utility model content
The utility model provides the spark plug of a kind of ignition effectiveness height and long service life.In order to realize the foregoing invention purpose, the utility model has adopted following technological means:
A kind of spark plug comprises shell, and the inwall of portion's igniting place in the enclosure is provided with an annular saddle, is welded with the nickel pad of annular at annular saddle.
For the ease of placing the nickel pad and do not influence igniting, as preferably, the external diameter of described nickel pad equals internal diameter of outer cover, and the internal diameter of nickel pad is less than or equal to the internal diameter of annular saddle;
The beneficial effects of the utility model are: the utility model is provided with an annular saddle at the inwall of shell igniting place, be welded with the nickel pad of annular at annular saddle, and the nickel pad has anti-oxidant, corrosion resistant characteristics, so useful life that can extending plug.
Description of drawings
Fig. 1 is the structural representation of the utility model spark-plug shell;
Fig. 2 is the cutaway view of nickel pad.
Embodiment
Below in conjunction with accompanying drawing, the preferred implementation of a kind of spark plug of the utility model is made detailed description:
As shown in Figure 1 and Figure 2, a kind of spark plug comprises shell 1, inwall in shell 1 inner igniting place is provided with an annular saddle 2, be welded with the nickel pad 3 of annular at annular saddle 2, the external diameter of described nickel pad 3 equals shell 1 internal diameter, and the internal diameter of nickel pad 3 is less than the internal diameter of annular saddle 2.
Claims (2)
1. a spark plug comprises shell, it is characterized in that: the inwall of portion's igniting place in the enclosure is provided with an annular saddle, is welded with the nickel pad of annular at annular saddle.
2. a kind of spark plug according to claim 1, it is characterized in that: the external diameter of described nickel pad equals internal diameter of outer cover, and the internal diameter of nickel pad is less than or equal to the internal diameter of annular saddle.
