Abstract
The utility model provides a rubber lining flange sealing structure which comprises a flange and a connecting piece connected with the flange. A rubber lining layer is arranged on the end face, toward the connecting piece, of the flange. A sealing ring matched with the rubber lining layer along the axial direction of the flange is arranged between the rubber lining layer and the connecting piece. A groove is formed in the end face, toward the sealing ring, of the rubber lining layer. The sealing ring is clamped into the groove and is matched with the rubber lining layer. The rubber lining flange sealing structure is simple in detachment of the flange, good in sealing effect, and favorable to fixation of screws, and solves the problems that a traditional rubber lining flange rubber slab is prone to water leakage due to non-tight sealing, threads are damaged and locked due to over-tight locking of screws, a flange sealing slab can be torn easily due to detection, maintenance and re-detachment, and the like.

Technical problem to be solved in the utility model is to provide a kind of line with rubber flange seal structure, flange dismounting is simple, good sealing effect, be conducive to screw and fix, and has solved that traditional line with rubber flange offset plate poorly sealedly easily leaks, screw crosses locking and cause that silk mouthful mashed tooth is locked, problems such as the flange seal offset plate easily tears are heavily torn in maintenance open.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of line with rubber flange seal structure, comprise flange and the link that is connected with flange, described flange is provided with the line with rubber layer towards the end face of link, be provided with the seal ring that axially cooperates with the line with rubber layer along flange between described line with rubber layer and the link, described line with rubber layer is provided with groove towards the end face of seal ring, and described seal ring sticks in the groove and cooperates with the line with rubber layer.
As preferably, described seal ring is ring body, and described groove is circular groove, and the central shaft of described seal ring, groove and flange is located along the same line.
As preferably, described seal ring is O type circle, and the section radius of described O type circle is greater than the groove depth of groove.
As preferably, the section radius of described O type circle is greater than the groove depth 0.1-1mm of groove.
As preferably, the notch of described groove is curved.
As preferably, described link is flange or blind flange.
As preferably, described flange is connected by retaining screw with link.
As preferably, also be provided with the line with rubber layer on the described link, described seal ring is located between two line with rubber layers, and the line with rubber layer on the described link also is provided with groove on the end face of seal ring, and the groove line with rubber layer interior and on the link that described seal ring sticks into the line with rubber layer on the link cooperates.
Beneficial effect:
A kind of line with rubber flange seal structure that the utility model adopts technique scheme to provide, flange dismounting is simple, good sealing effect, be conducive to screw and fix, and has solved that traditional line with rubber flange offset plate poorly sealedly easily leaks, screw crosses locking and cause that silk mouthful mashed tooth is locked, problems such as the flange seal offset plate easily tears are heavily torn in maintenance open.
