Abstract
The utility model discloses a seal ring for a filter. The seal real comprises an annular ring body, the cross section of the ring body is in a cone shape, the lower surface of the ring body is a plane, and the upper surface of the ring body is an arc. The arc of the seal ring is in a line contact when contacting with a filter seat, compression of the seal ring can be at a best state, sealing performance is improved, and disassembling is further facilitated.
Description
Technical field
The utility model relates to a kind of filter cleaner seal ring.
Background technique
Filter cleaner surface of contact and the filter block surface of contact of the seal ring of existing filter cleaner all adopt planar design, its cross section is for using rectangular configuration, in the filter cleaner installation process, it while starting to contact with filter block due to rectangular seal, is exactly the face contact, the compression of seal ring is not the optimum state, the poor sealing phenomenon occurs, cause leakage of oil, simultaneously, filter cleaner is after normal operation, and under the effect of engine oil pressure, it is extremely difficult that oil filter is changed dismounting, can change after filter cleaner need to being destroyed, cause very large inconvenience to the maintaining of filter cleaner.
The model utility content
The purpose of this utility model is to overcome the defect existed in prior art, and a kind of filter cleaner seal ring is provided, and sealing is good, convenient disassembly.
For achieving the above object, the technical solution of the utility model has been to provide a kind of filter cleaner seal ring, by nitrile rubber, made, comprise ringwise circle body, the cross section of described circle body is tapered, the lower surface of described circle body is plane, and the upper surface of described circle body is arc shaped surface.
As preferably, the upper surface of described circle body is the semicircle cambered surface.
Advantage of the present utility model is with beneficial effect: be the line contact when arc shaped surface of seal ring contacts with filter block, the compression of seal ring can be reached to the optimum state, improve sealing, dismounting is also more convenient in addition.
The accompanying drawing explanation
Fig. 1 is schematic cross-section of the present utility model.
In figure: 1, upper surface; 2, lower surface; 3, circle body.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
Shown in Fig. 1, a kind of filter cleaner seal ring, made by nitrile rubber, comprises ringwise circle body 3, and the cross section of described circle body 3 is tapered, and the lower surface 2 of described circle body 3 is plane, and the upper surface 1 of described circle body 3 is arc shaped surface.
Shown in Fig. 1, the upper surface 1 of described circle body 3 is the semicircle cambered surface.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. a filter cleaner seal ring, made by nitrile rubber, it is characterized in that: comprise ringwise circle body, the cross section of described circle body is tapered, and the lower surface of described circle body is plane, and the upper surface of described circle body is arc shaped surface.
