Abstract
The invention discloses a filtering element end cover. The filtering element end cover comprises an end cover outer sleeve (1) and an end cover inner sleeve (2), wherein the end cover outer sleeve (1) and an end cover inner sleeve (2) are of concentric structures and are connected through an annular silica gel sealing fin (3). According to the filtering element end cover provided by the invention, the silica gel sealing fin of a layer of soft body is additionally arranged between the filtering element end cover and a filtering element contact region, the sealability of the edge of a filtering element is improved, the filtering effect of fluid is improved, the design is simple, the realization is easy, the cost is low, and the filtering element end cover has a favorable application prospect.
Description
Technical field
The present invention is specifically related to a kind of end cover of filter element, belongs to fluid purification.
Background technology
at present, filter core is for removing a small amount of solid particle of liquid or air, can protect the normal operation of equipment or the cleaning of air, after entering when fluid the filter core that is equipped with the certain specification filter screen, its impurity is blocked, and the stream thing of cleaning flows out by filter core, thereby be widely used, because filter core can filter impurity in fluid, higher to sealing requirements, present end cover of filter element is connected to one for filter core, the buckles that are distributed in the end cover of filter element inboard that adopt connect more, sealing effectiveness is not good, impurity can overflow from end cover of filter element and filter core junction, affect the filter effect of fluid.
Summary of the invention
In order to overcome the bad problem of end cover of filter element and filter core connection sealing in prior art.End cover of filter element provided by the invention by the silica gel sealing sheet at end cover of filter element and filter core contact area increase one deck software, can increase the sealing at filter core edge, increases the filter effect of fluid.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of end cover of filter element is characterized in that: comprise end sleeve of top cover cylinder and end cap inner sleeve, described end sleeve of top cover cylinder and end cap inner sleeve are concentric structure, and between silica gel sealing sheet by an annular connect.
Aforesaid a kind of end cover of filter element is characterized in that: the thickness of described silica gel sealing sheet is for covering half of outer sleeve length.
Aforesaid a kind of end cover of filter element is characterized in that: described end sleeve of top cover cylinder and end cap inner sleeve adopt rigid plastics to make.
The invention has the beneficial effects as follows: end cover of filter element of the present invention, by the silica gel sealing sheet at end cover of filter element and filter core contact area increase one deck software, can increase the sealing at filter core edge, increase the filter effect of fluid, simplicity of design, easily realize, with low cost, have a good application prospect.
Description of drawings
Fig. 1 is the Facad structure figure of end cover of filter element of the present invention.
Fig. 2 is the structure figure of end cover of filter element of the present invention.
The mark implication of accompanying drawing is as follows:
1: the end sleeve of top cover cylinder; 2: the end cap inner sleeve; 3; The silica gel sealing sheet.
The specific embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
as shown in Figures 1 and 2, a kind of end cover of filter element, comprise end sleeve of top cover cylinder 1 and end cap inner sleeve 2, end sleeve of top cover cylinder 1 and end cap inner sleeve 2 are concentric structure, and between silica gel sealing sheet 3 by an annular connect, the outer wall of the inwall of end sleeve of top cover cylinder 1 and end cap inner sleeve 2 is close to outer surface and the inner surface of filter core, filter core is clipped in the middle, at first end sleeve of top cover cylinder 1 and end cap inner sleeve 2 are inserted in filter core during installation, then the silica gel sealing sheet 3 after heating adds rear being arranged on rapidly between end sleeve of top cover cylinder 1 and end cap inner sleeve 2, after silica gel sealing sheet 3 is cooling, side seal with filter core, good airproof performance, the thickness of silica gel sealing sheet 3 is for covering half of outer sleeve 1 length, can guarantee filter element tightness, end sleeve of top cover cylinder 1 and end cap inner sleeve 2 adopt rigid plastics to make, firmly and cost cheap, end cover of filter element of the present invention, can increase the sealing at filter core edge, improve the filter effect of fluid, simplicity of design, easily realize, with low cost, have a good application prospect.
Above demonstration and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (3)
