Abstract
The utility model discloses a canned type flange connects, connect the body including cup jointing on the body and cup jointing the complex with the flange, connect be equipped with on the body with the complex boss is cup jointed in the shaft hole of flange, be equipped with on the boss and vertically run through whole joint body and body and cup joint the complex centre bore, connect be equipped with on the body with the connecting hole that the locating hole is coaxial and the front and back is link up of flange, it keeps away from to connect the body the surface of flange be equipped with with the coaxial sealed caulking groove of connecting hole, inflatable seal pads installed in the embedding in should sealed caulking groove, this inflatable seal pad is the annular structure, its inner wall and the inner wall looks parallel and level of connecting hole. The utility model discloses make the inflatable seal pad can to fill the clearance that connects between body and the bolt and nut, guarantee hookup location's leakproofness.
Description
Technical field
The utility model belongs to mechanical parts technical field, is specifically related to a kind of sealed type flanged joint.
Background technique
Flange arrangement form is varied, most flanges connects as flange docking in left and right connects, but the docking end face due to flange inevitably has gap to produce, and therefore there will be larger sealing problem, if use conventional seals circle also can cause leakage problem after a long time use.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of sealed type flanged joint, and it effectively can solve the problem that existing flanged joint easily causes poor sealing.
The technological scheme that the utility model adopts is: a kind of sealed type flanged joint, comprise and be socketed on body and be socketed with flange the joint body coordinated, described joint body is provided with and is socketed with the axis hole of described flange the boss coordinated, described boss is provided with and longitudinally runs through whole joint body and be socketed with body the center hole coordinated, described joint body is provided with and attachment hole that front and back through coaxial with the positioning hole of described flange, described joint body is provided with the sealing caulking groove coaxial with described attachment hole away from the surface of described flange, sealing caulking groove is embedded in and is provided with inflatable seal pad, this inflatable seal pad structure in the form of a ring, its inwall is mutually concordant with the inwall of described attachment hole.
As preferably, be provided with positioning convex in described sealing caulking groove, the surface that described inflatable seal pad is relative with above-mentioned sealing caulking groove is provided with the positioning groove mated with above-mentioned positioning convex.
As preferably, described inflatable seal pad is mutually concordant with the surface of described joint body away from the surface of described positioning convex.
The beneficial effects of the utility model are: because the utility model is provided with sealing caulking groove around attachment hole, inflatable seal pad is set in sealing caulking groove simultaneously, when utilizing bolt and nut to connect, can act on inflatable seal pad, inflatable seal pad is carried out compacting, make inflatable seal pad can fill gap between joint body and bolt and nut, ensure the sealing of link position.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, body; 2, joint body; 3, boss; 4, attachment hole; 5, caulking groove is sealed; 6, inflatable seal pad.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of sealed type flanged joint, comprise and be socketed on body 1 and be socketed with flange the joint body 2 coordinated, described joint body 2 is provided with the boss 3 being socketed with the axis hole of described flange and coordinating, described boss 3 is provided with and longitudinally runs through whole joint body 2 and be socketed with body 1 center hole coordinated, described joint body 2 is provided with and attachment hole 4 that front and back through coaxial with the positioning hole of described flange, described joint body 2 is provided with the sealing caulking groove 5 coaxial with described attachment hole 4 away from the surface of described flange, sealing caulking groove 5 is embedded in and is provided with inflatable seal pad 6, this inflatable seal pad 6 structure in the form of a ring, its inwall is mutually concordant with the inwall of described attachment hole 4.
Because the utility model is provided with sealing caulking groove 5 around attachment hole 4, inflatable seal pad 6 is set in sealing caulking groove 5 simultaneously, when utilizing bolt and nut to connect, can act on inflatable seal pad 6, inflatable seal pad 6 is carried out compacting, make inflatable seal pad 6 can fill gap between joint body 2 and bolt and nut, ensure the sealing of link position.
As preferably, positioning convex is provided with in described sealing caulking groove 5, the surface that described inflatable seal pad 6 is relative with above-mentioned sealing caulking groove 5 is provided with the positioning groove mated with above-mentioned positioning convex, positioning convex and positioning groove cooperatively interact and make the installation of inflatable seal pad 6 more firm, avoid coming off; Inflatable seal pad 6 is mutually concordant with the surface of described joint body 2 away from the surface of described positioning convex.
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
