Abstract
A novel radially-sealed PU (polyurethane) air filter element consists of an upper end cover, an outer protective screen, a filter element paper roll, a central pipe and a lower end cover which are sequentially assembled into the complete filter element. The upper end cover of the air filter element is provided with a multi-stage stepped guide mounting structure, the guide size is large, the filter element is easy to mount and dismount, the guide mounting size can be quickly transited to the radial sealing size, the maintenance, mounting and dismounting operability of the filter element is improved, meanwhile, the height of a sealing surface is guaranteed, and the sealing reliability is guaranteed.
Description
Technical field
The utility model relates to a kind of air filter core, particularly a kind of novel radial seal polyurethane air filter core.
Background technology
As everyone knows, the polyurethane filter core of radial seal, relies on the interference fit of the corresponding constructions such as filter core upper end cover medial surface and assembly protecgulum sealing ring to form sealing, and filter core size of seal contact face need to provide the larger magnitude of interference with assurance sealing reliability.Traditional radial seal polyurethane filter core, filter core upper end cover medial surface has the guide frame of chamfering, but this guide frame is little, and in the situation that sealing Interference size is larger, this guiding size is little, and filter core dismounting when car load maintaining is very difficult.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of novel radial seal polyurethane air filter core, thereby solves the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of novel radial seal polyurethane air filter core, comprise upper end cover, bottom end cover, central tube, outer protecting wire net, filter core paper roll, central tube is placed in filter core paper roll, outer protecting wire net is enclosed within outside filter core paper roll, upper and lower end cap is polyurethane, moulding in mold cavity, central tube, outer protecting wire net, filter core paper roll are embedded in upper and lower end cap, and above parts are assembled into complete filter core according to the order of sequence.It is characterized in that, upper end cover medial surface step number is more than two-stage; From top to bottom, diameter dimension is along with step structure reduces gradually for upper end cover medial surface, progressively by guiding size to closure size transition.
Adopt the novel radial seal polyurethane air filter core of technique scheme, it is characterized in that: described upper end cover medial surface the first half is multistage stair-stepping installation guide frame, medial surface the latter half is sealing surface, by multistage ladder being set in filter core medial surface the first half, guiding size has larger matched in clearance, and can realize filter core by the matched in clearance of the size that leads the interference fit fast transition to closure size, increasing guiding size, improve filter core maintaining dismounting operability simultaneously, guarantee filter core sealing area, guaranteed sealing reliability.
Compared with prior art, the utility model beneficial effect is: filter core designs multistage guide frame, and guiding installation dimension gap is large, facilitates filter core to install, and the size fast transition that can make to lead is to closure size, guarantees that sealing area is enough large, and sealing reliability strengthens.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the half sectional view of the utility model radial seal polyurethane filter core;
Fig. 2 is Fig. 1 partial enlarged view.
In Fig. 1: 1. outer protecting wire net 3. filter core paper roll 4. central tube 5. bottom end covers of upper end cover 2..
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Referring to Fig. 1, Fig. 2, a kind of novel radial seal polyurethane air filter core, comprises upper end cover 1, outer protecting wire net 2, filter core paper roll 3, central tube 4, bottom end cover 5.As shown in Figure 2, central tube 4 is placed in filter core paper roll 3, plays support frame effect, outer protecting wire net 2 is enclosed within outside filter core paper roll 3, plays protective action, and upper end cover 1, bottom end cover 5 are polyurethane material, in mold cavity moulding, central tube, outer protecting wire net, filter core paper roll are embedded in upper and lower end cap.Upper end cover 1 medial surface the first half is multistage stairstepping, rise guide effect is installed, the latter half is sealing surface, by the multistage stepped design of upper end cover medial surface, realize filter core by the size fast transition that leads to closure size, guiding installation property is good, guarantees the height of sealing surface simultaneously, guarantees sealing reliability.
Basic structure of the present utility model and technical essential have more than been shown; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates feature of the present utility model; do not departing under the prerequisite of spirit and scope of the present utility model; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
