Abstract
The utility model provides a sealing rubber gasket that filter core was used, belongs to sealing technique field for the filter core for the installation bearing of sealed protection filter core, sealing rubber gasket construction include the suit at filter core erection joint department, and annular flaky gasket body, and the symmetry sets up at the protruding compression seal structure who constitutes of the annular of the upper and lower terminal surface of gasket body. It has, and simple structure, leakproofness are good, long service life's advantage.
Description
Technical field
The utility model belongs to filter core technical field of sealing technology, is specifically related to a kind of caulking gum pad of filter core.
Background technique
Filter cartridge construction comprises filter screen body, is arranged on the installation of filter screen body mounting end flat board, and is welded on the screw rod installed on flat board.The sealing configuration of existing filter core screw rod joint often adopts O type circle sealing means, but there is following drawback: the installation slab construction of filter core mounting end is plane, does not arrange groove thereon, because the optimal seal effect of O type circle need realize by groove, therefore application O type circle sealing means is very unsuitable, even if adopt O type circle also can follow the string and sealability because of long-time excess compression; The means of fixation of filter core is fastened on attachment face by screw rod suit O type circle, install between dull and stereotyped and attachment face and there is gap because of O type circle, therefore O type circle can be used as and installs balance pivot between dull and stereotyped and attachment face, when the existence of this balance pivot can free vibrations in filter core installation process or in using process, cause screw rod generation bending or filter screen body and the generation of sealing-off problem between flat board is installed.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of caulking gum pad of filter core, and it has, and structure is simple, the advantage of good airproof performance, long service life.
The technical solution adopted in the utility model is: a kind of caulking gum pad of filter core; for the installation bearing of seal protection filter core; caulking gum gasket construction comprises and is sleeved on filter core and installs joint and the shim body of annular slice, and the compression seal structure that the annular protrusion being symmetricly set on the upper and lower end face of shim body is formed.
Further: the cross section semicircular in shape of annular protrusion, or rounding off is square, or rounding off is trapezoidal.
Filter cartridge construction comprises filter element body, is arranged on the screw rod that the installation of filter element body mounting end is dull and stereotyped and be welded on installation flat board, and described filter core is fixed on attachment face by means of screw rod, nut and caulking gum pad.
Adopt the beneficial effect that the utility model produces: the compression seal structure that the annular protrusion that (1) is arranged in shim body is formed, both can ensure the sealing between filter core and attachment face, caulking gum pad also can be avoided to produce inefficacy because of excess compression; (2) shim body and the area of contact of installing between dull and stereotyped and attachment face larger, can eliminate when adopting O type circle before this, in filter core, the balance pivot formed between dull and stereotyped and attachment face is installed, thus avoid in the problem installing and occur in using process sealing-off or screw rod bending between filter element body and installation flat board; (3) the utility model caulking gum pad has that structure is simple, the advantage of good airproof performance, long service life.
Accompanying drawing explanation
Fig. 1 is the utility model installment state schematic diagram;
Fig. 2 is structural representation of the present utility model;
In accompanying drawing: 1 is shim body, and 1-1 is annular protrusion, 2 is filter cores, and 2-1 is filter element body, and 2-2 installs flat board, and 2-3 is screw rod.
Embodiment
Referring to accompanying drawing 1-2; a kind of caulking gum pad of filter core; for the installation bearing of seal protection filter core 2; described caulking gum gasket construction comprises and is sleeved on filter core 2 and installs joint and the shim body 1 of annular slice, and the compression seal structure that the annular protrusion 1-1 being symmetricly set on the upper and lower end face of shim body 1 is formed.
The cross section semicircular in shape of annular protrusion 1-1, or rounding off is square, or rounding off is trapezoidal.
Filter core 2 structure comprises filter element body 2-1, is arranged on the dull and stereotyped 2-2 of the installation of filter element body 2-1 mounting end and is welded on the screw rod 2-3 installed on dull and stereotyped 2-2, and described filter core 2 is fixed on attachment face by means of screw rod 2-3, nut and caulking gum pad.Installing dull and stereotyped 2-2 is metal material, and screw rod 2-3 vertically installs on dull and stereotyped 2-2 to being welded on.
In the specific implementation, the annular protrusion 1-1 that shim body 1 is arranged forms the compression seal structure of caulking gum pad, both can ensure the sealing between filter core 2 and attachment face, caulking gum pad also can be avoided to produce inefficacy because of excess compression; Shim body 1 and the area of contact of installing between dull and stereotyped 2-2 and attachment face larger, can eliminate when adopting O type circle before this, in filter core 2, the balance pivot formed between dull and stereotyped 2-2 and attachment face is installed, thus avoid and installing and in using process, filter element body 2-1 is occurring and the problem of sealing-off and screw rod 2-3 bending between dull and stereotyped 2-2 is installed.
