Description
Technical field
The utility model relates to a kind of cleaner, particularly a kind of stable type fuel filter.
Background technology
At present, existing a kind of fuel filter includes housing; Be provided with inner chamber in the housing, be provided with the refill assembly in the inner chamber, housing is provided with oil-in, oil return opening and oil-out; Housing bottom also is provided with the dewatering outlet, and wherein, the refill assembly includes refill, positioning catheter, upper cover plate, lower cover; Refill is coated on the positioning catheter outside, and upper cover plate, lower cover are separately positioned on refill upper surface, the lower surface, is connected through fixing glue between refill assembly and the interior cavity wall.
But, the fuel filter of this structure, after long-time the use, the viscosity of fixing glue reduces, thereby makes that the location of refill assembly is not firm, and then makes that the service behaviour of fuel filter is unstable.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of prior art, the utility model provides a kind of stable type fuel filter, and long-time use can guarantee that still refill assembly location is firm, and then guarantees the stable work in work of fuel filter.
The technical scheme of the utility model: a kind of stable type fuel filter, include housing, in described housing, be provided with inner chamber; Be provided with the refill assembly in the inner chamber, housing is provided with oil-in, oil return opening and oil-out, and housing bottom also is provided with the dewatering outlet; Wherein, Described refill assembly includes refill, positioning catheter, upper cover plate, lower cover, and refill is coated on the positioning catheter outside, and described upper cover plate, lower cover are separately positioned on the upper surface, lower surface of refill; Oil return opening is communicated with positioning catheter; It is characterized in that: cavity wall circumferentially is extended with the circular orientation boss along oil return opening in described in inner chamber, and described upper cover plate is set on the circular orientation boss, and described circular orientation boss extends in the positioning catheter.
Adopt technique scheme, described refill assembly is set on the circular orientation boss through upper cover plate, so long-time use can guarantee that still refill assembly location is firm, and then guarantees the stable work in work of fuel filter.
The further setting of the utility model: also be provided with sealing ring between described upper cover plate and the circular orientation boss.
Adopt above-mentioned further setting, the fluid after can preventing to filter through described sealing ring mixes with unfiltered fluid, causes unnecessary trouble.
Further being provided with again of the utility model: described housing includes upper shell, the lower house that split is provided with; Described dewatering outlet is arranged on the lower house; Described refill assembly is arranged in the upper shell, and described oil-in, oil return opening and oil-out also are arranged on the upper shell.
Adopt above-mentionedly further to be provided with again, described housing split be provided with, can be conveniently to installation, the maintenance of inner refill assembly.
