Abstract
The invention belongs to the technical field of vehicle filter cores, and particularly relates to a filter core pressing sealing structure in high-temperature and high-pressure environment. In order to realize the goal that a filter core pressing sealing mechanism can adapt to the high-temperature and high-pressure environment, the filter core pressing sealing structure in the high-temperature and high-pressure environment provided by the invention is characterized in that the appearance of the pressing sealing structure is in a wedge shape, the top of the wedge-shaped pressing sealing mechanism is provided with a semicircular groove, the deformation quantity of the wedge-shaped pressing sealing structure is 2 to 3mm, and the wedge-shaped pressing sealing structure is made of silicon gel materials with the highest resistance temperature being 200 DEG C. Therefore, the filter core pressing sealing structure has the advantages that the process is simple, the sealing is reliable, the cost is low, and the resistance on the high-temperature and high-pressure environment can be realized.
Description
Technical field
The invention belongs to vehicle filter core technical field, be specifically related to high temperature and high pressure environment lower filter pressing sealing structure for a kind of vehicle.
Background technique
Filter core is the important component part of air-strainer, and its effect is the particulate matter in the filtering engine charge, prevents that particulate matter from entering the engine piston cylinder, causes piston and cylinder body friction and damages motor.At present, air-strainer is positioned at the engine supercharger front end, and Environmental Conditions is the normal temperature and pressure state.Mostly adopt the press seal form between filter core and air filter housing.As shown in Figure 2, pressing sealing structure adopts bipeltate more, and profile is simple wedge shape or square protrusion structure.
Along with the development of engine charge filtering technique, the high pressure admission filtering technique has appearred.Its principle is that air-strainer first-level filtering (strainer) and secondary filter (secondary filter) is separated, and wherein first-level filtering is positioned over the engine compressor front end, and the secondary filter is positioned over gas compressor and motor.Therefore, change has occurred in the Environmental Conditions of two stage filter, in the high temperature and high pressure environment, traditional filter core pressing sealing structure is that material and structural type all can't meet the sealing usage requirement under this environment, for this reason, how developing a kind of filter core pressing sealing structure that can adapt to high temperature and high pressure environment, to those skilled in the art, is the direction and goal that very urgent needs are striven for.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is to make vehicle can adapt to high temperature and high pressure environment with the filter core compacting sealing mechanism.
(2) technological scheme
For solving the problems of the technologies described above, pressing sealing structure under a kind of high temperature and high pressure environment provided by the invention, the profile of this pressing sealing structure is wedge shape, at the top of described wedge shape compacting sealing mechanism, is provided with a semi-circular recesses.
Wherein, the radius of described semi-circular recesses is 0.25～0.3 times of described wedge pressure tightening seal structure height, the radius of the both sides circular arc of described semi-circular recesses is 0.3～0.45 times of described wedge pressure tightening seal structure height, and the width of described wedge pressure tightening seal structural base is 0.7～1 times of its height.
Wherein, the amount of deformation of described wedge shape pressing sealing structure is 2～3mm.
Wherein, the silica gel material that described wedge shape pressing sealing structure adopts tolerable temperature to be up to 200 ℃ is made.
(3) beneficial effect
Compared with prior art, the present invention possesses following beneficial effect:
Pressing sealing structure under a kind of high temperature and high pressure environment provided by the invention, structural manufacturing process is simple, sealing is reliable, cost is low, particularly under high temperature and high pressure environment, the top semi-circular recesses of wedge-type seal structure can guarantee the expansion space of silica gel, make sealing configuration remain uniform stressed, not there will be local protuberance and cause filter core and air filter housing sealing surface the phenomenon in gap to occur.
The accompanying drawing explanation
Fig. 1 is sealed structural representation provided by the invention;
Fig. 2 is the conventional seals structural representation;
Fig. 3 is the enforcement structural representation of sealing configuration provided by the invention.
Embodiment
For making purpose of the present invention, content and advantage clearer, below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, pressing sealing structure under a kind of high temperature and high pressure environment provided by the invention, the profile of this pressing sealing structure is wedge shape, at the top of described wedge shape compacting sealing mechanism, is provided with a semi-circular recesses.
Wherein, the radius of described semi-circular recesses is 0.25～0.3 times of described wedge pressure tightening seal structure height, the radius of the both sides circular arc of described semi-circular recesses is 0.3～0.45 times of described wedge pressure tightening seal structure height, and the width of described wedge pressure tightening seal structural base is 0.7～1 times of its height.
Wherein, the silica gel material that described wedge shape pressing sealing structure adopts tolerable temperature to be up to 200 ℃ is made, and guarantees the reliably working of compressing structure under high temperature and high pressure environment.
As shown in Figure 3, high temperature and high pressure environment lower filter pressing sealing structure 2 use rubber liquid provided by the invention and filter core 1 end face are bonding firmly, filter core 1 is put into to the designated mounting position of high pressure secondary filter air filter housing 3, and use air-strainer hold down gag 2 that filter core 1 and air filter housing 3 are compressed by filter core, the amount of deformation of filter core pressing sealing structure 2 is about 2～3mm.After filter core pressing sealing structure 2 produces the deformation of 2～3mm compression, the semi-circular recesses at wedge-shaped structure top can provide unnecessary expansion space for this filter core pressing sealing structure 2 under high temperature and high pressure environment, thereby guarantee that filter core pressing sealing structure 2 remains the press seal state of uniform stressed, prevents the generation of seal failure phenomenon.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
