Abstract
The utility model relates to an imporoved head of a closed type heater plug. The utility model adopts a cuvette-shaped protective sleeve structure, wherein, one end is closed, and the other end is opened. The front end of a heating wire is extended into a protective sleeve and is led to the tail part of a heater plug through a central rod to be connected with one pole of an accumulator. The back end of the heating wire is welded on an opening position of the protective sleeve and is connected with the other pole of the accumulator through a casing body. In the structure, the heater plug is not required to be sealed in an argon arc welding mode. Thus, the quality problem of the heater plug, which is caused by weld defects of the argon arc welding is prevented, and the stable quality is ensured. The novel closed type heater plug has the characteristics of reasonable structure, simple manufacturing process, long service life, low cost, etc.
Description
Novel block type glow plug belongs to the auxiliary device of using when diesel engine starts winter.
Enclosed type glow plug head configuration is that a metal seals pipe, the in-built electrical heated filament, the head of glow plug stretches at diesel combustion indoor, switch on to electric heating wire earlier during diesel engine starting, the glow plug head temperature is raised to about 850 ℃, spray into diesel oil this moment, and the diesel oil of dewizations is sprayed on the glow plug head of high temperature, burns rapidly immediately, diesel engine starting.
The head of existing domestic and international enclosed type glow plug is with electric heating wire coiled screwed pipe shape, be installed in the protective metal shell of heat-resistance stainless steel, sheath is the tubular structure of two opening, electric heating wire is inserted in the sheath, the front end of electric heating wire is welded in the head of sheath and seals with argon arc welding, and sheath links to each other with housing, connects a utmost point of storage battery, the rear end of electric heating wire is connected with wiring screw rod, is drawn another utmost point that connects storage battery by the glow plug afterbody.Play insulation and protective action with stupalith fillings such as magnesium oxide or aluminium oxide between electric heating wire and the protective metal shell; because the head of enclosed type glow plug stretches in the firing chamber of diesel engine; the effect of high-temperature fuel gas when always being subjected to diesel engine work; the quality of head argon arc welding quality directly has influence on the quality and the life-span of enclosed type glow plug; as weld defectives such as producing slag inclusion; often make the easy ablation of head of enclosed type glow plug and damage the shortening in working life.
The utility model provides a kind of employing one end sealing, the glow plug of the test tube shape jacket structure of an end opening.Have simple in structurely, cost is low, reliable in quality, characteristics such as long service life.
Solving the technical solution of the utility model is the structural design of improving the glow plug head, the tubular sheath structure of two through hole is made into a sealing, the test tube shape jacket structure of an opening, the front end of helical electric heating wire is welded on the center-pole by electric heating wire spiral center, the afterbody that is drawn out to glow plug by wiring screw rod by center-pole connects a utmost point of storage battery, electric heating wire extend in the sealing sheath, but the front end of electric heating wire discord sealing sheath links to each other, and by be connected with housing another utmost point of storage battery of the opening that the rear end of electric heating wire is welded on the sealing sheath.Adopting new technology has solved the technical problem of stupalith such as filling aluminium oxide or magnesium oxide between electric heating wire and the protective metal shell, makes sealing glow plug reliable in quality, long service life.
The utility model has the advantages that:
1, the life-span is long, because the head of the utility model enclosed type glow plug does not adopt the argon arc welding sealing technique, avoided owing to the many disadvantages that causes is sealed in argon arc welding, under the situation of the identical heat-resistance stainless steel sheath material of effect, prolonged the working life of glow plug.
2, steady quality, the enclosed type glow plug that adopts argon arc welding to seal will machine away welding slag after welding, often make to seal metal thickness and differ, and has influence on the life-span and the steady quality of glow plug.And the utility model enclosed type glow plug head metal thickness is decided by maching dimension, and thickness is even, has guaranteed steady quality.
3, owing to do not adopt the argon arc welding sealing technique, technology is simple, and cost is low, and is easy to utilize.
Accompanying drawing is the utility model embodiment's a structural representation.
Be further described in conjunction with the accompanying drawings, the sealing of one end, the test tube shape protective metal shell 1 of one end opening, in helical electric heating wire 2 is arranged, the front end of helical electric heating wire 2 is welded on the center-pole 3, center-pole 3 is connected with wiring screw rod 7, the rear end of helical electric heating wire 2 is welded on the test tube shape protective metal shell 1, be pressed into housing 5, anti-limit compresses insulator 6 on the housing 5, insulate with aluminium oxide 4 between center-pole 3, helical electric heating wire 2 and the test tube shape protective metal shell 1.
