Abstract
The utility model relates to a gasoline filter with a seal ring. The gasoline filter comprises a casing and a paper element assembly, wherein the paper element assembly is arranged in the casing, the paper element assembly comprises a paper element, a conduit, an upper end cover and a lower end cover, the paper element is wrapped on the conduit, the upper end cover and the lower end cover are respectively pressed on the upper and lower ends of the paper element, the casing is provided with a gasoline inlet and a gasoline outlet, an annular positioning boss extends from the inner wall of the casing to the inside of the casing along the circumferential direction of the gasoline outlet, a seal ring is sleeved on the annular positioning boss, the side wall of the seal ring is provided with two layers of steps, a through hole is arranged in a position (corresponding to that of the seal ring) of the lower end cover, a tongue piece extends from the lower end cover to the inside of the conduit along the circumferential direction of the through hole, and the tongue piece is both contacted with the surfaces of the two layers of steps so as to form a double seal. By adopting the technical scheme above, the utility model provides the gasoline filter with the seal ring, so that the sealing between the annular positioning boss and the lower end cover is good, and the occurrence of a phenomenon that unfiltered oil directly flows out of a space between the annular positioning boss and the lower end cover is not caused.
Description
Technical field
The utility model relates to the filter cleaner field, particularly a kind of gasoline filter that has seal ring.
Background technique
At present, existing a kind of gasoline filter includes shell; Refill assembly in the enclosure is set, and wherein, the refill assembly includes refill, conduit, upper end cap, lower end cap; Refill is coated on the conduit, and upper end cap, lower end cap are pressed on refill upper end, lower end respectively, and shell is provided with filler opening, oil outlet; Outer casing inner wall circumferentially is extended with the circular orientation boss along oil outlet in shell, lower end cap is set in the location that forms on the circular orientation boss the refill assembly.
But, the gasoline filter of this structure, poor sealing between circular orientation boss and the lower end cap makes unfiltered fluid directly between circular orientation boss and lower end cap, flow out easily.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology; The utility model provides a kind of gasoline filter that has seal ring; Make and can not cause unfiltered fluid directly to take place by good airproof performance between circular orientation boss and the lower end cap from the phenomenon that flows out between circular orientation boss and the lower end cap.
The technological scheme of the utility model: a kind of gasoline filter that has seal ring, include shell, refill assembly in the enclosure is set; Wherein, the refill assembly includes refill, conduit, upper end cap, lower end cap, and refill is coated on the conduit; Upper end cap, lower end cap are pressed on refill upper end, lower end respectively; Shell is provided with filler opening, oil outlet, and outer casing inner wall circumferentially is extended with the circular orientation boss along oil outlet in shell, it is characterized in that: be arranged with seal ring on the described circular orientation boss; Described seal ring sidewall is provided with two-layer step; The corresponding seal ring of lower end cap position is provided with through hole, and described lower end cap is along being extended with tongue piece in the circumferential conductive pipe of through hole, the formation double seal of all conflicting of tongue piece and two-layer step surface.
Adopt technique scheme; The seal ring that is provided with; The tongue piece of lower end cap and two-layer step surface all conflict form double seal can be so that good airproof performance between circular orientation boss and the lower end cap can not cause unfiltered fluid directly to take place from the phenomenon that flows out between circular orientation boss and the lower end cap.
The further setting of the utility model: described shell includes housing, gland, and described housing and gland welding are fixing.
Adopt above-mentioned further setting, make housing be connected with cover plate reliably, easy to process, cost is low.
Further being provided with again of the utility model: be connected through fixing glue between described refill and upper end cap, the lower end cap.
Adopt above-mentioned further setting again, it is firm, easy to process to make that refill is connected with upper end cap, lower end cap.
