Description
Technical field
A kind of ring flange docking sealing gasket is the utility model is related to, belongs to sealing device field.
Background technology
Sealing ring is conventional seal member in the prior art.In the prior art, method pulling plate needs to pass through sealing in docking
Pad is sealed.But existing sealing ring is inconvenient to position in use, local derviation is easily put when mounted and causes influence close
Seal effect.And sealing ring after mounting due to pre- at flange plate bolt hole interspace it is larger, so sealing gasket is in flange
Sealing effectiveness at valve snail keyhole is poor.
Utility model content
In view of the deficienciess of the prior art, technical problem to be solved in the utility model is to provide a kind of ring flange
Docking sealing gasket, convenient positioning, improves the sealing effectiveness at flange plate bolt hole.
In order to solve the above technical problems, the utility model adopts the technical scheme that, a kind of ring flange docking sealing gasket,
Include the sealing ring (1) of annular, the center of sealing ring (1) is provided with circular port, the looping pit both sides difference of sealing ring (1)
A connecting cylinder (2) for being used to insert in pipeline is connected with, sealing ring (1) is provided with some bolt through-holes (3), bolt through-hole
(3) both sides are connected to a bolt hole connecting cylinder (4) for being used to insert flange valve snail keyhole, bolt hole connecting cylinder (4)
For cylinder, the stage casing internal diameter of bolt through-hole (3) is more than the internal diameter at bolt through-hole (3) both ends.
Optimization, above-mentioned ring flange docking sealing gasket, the sealing ring (1), connecting cylinder (2), bolt hole connecting cylinder
(4) it is integrally formed setting.
Optimization, above-mentioned ring flange docking sealing gasket, the sealing ring (1) is interior to be provided with a metal support chip (6),
The shape of metal support chip (6) is set with the form fit of sealing ring (1).
Optimize, above-mentioned ring flange docking sealing gasket, be provided with thickening washer (7) on the outside of the sealing ring (1), add
The thickness of thick washer (7) is more than the thickness of sealing ring (1).
Optimization, above-mentioned ring flange docking sealing gasket, the thickening washer (7) is interior to be provided with layer of silica gel (8).
In the technical scheme of the application, add for inserting the connecting cylinder in pipeline (2) and for inserting flange valve snail
The bolt hole connecting cylinder (4) of keyhole, so when sealing gasket is placed, it can be connected by the way that connecting cylinder (2) grafting is entered into ring flange
Pipeline, then by bolt hole connecting cylinder (4) insert flange valve snail keyhole, the position of flangeseal pad can thus be entered
Row is positioned and fixed, and prevents sealing gasket from putting partially and causing the bad situation of sealing effectiveness to occur.And by bolt hole connecting cylinder
(4) after inserting flange valve snail keyhole, bolt passes through bolt through-hole (3).Because the stage casing internal diameter of bolt through-hole (3) is more than bolt mistake
The internal diameter at hole (3) both ends, when bolt passes through bolt through-hole (3), bolt can extrude bolt hole company at bolt through-hole (3) both ends
Connect cylinder (4) so that the outer wall extruding flange valve snail keyhole inwall of bolt hole connecting cylinder (4), carried by increasing contact seal pressure
Sealing effectiveness at high bolt hole.The thickness of thickening washer (7) is more than the thickness of sealing ring (1), so in two ring flanges pair
After connecing, thickening washer (7) is squeezed rear internal layer of silica gel (8) and is squeezed so that thickening washer (7) and ring flange connect
Touch pressure increase, the seal contact pressure of increase thickening washer (7) and ring flange, further increases sealing effectiveness.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Technical characterstic of the present utility model is expanded on further with specific embodiment below in conjunction with the accompanying drawings.
The utility model is a kind of ring flange docking sealing gasket, includes the sealing ring (1) of annular, in sealing ring (1)
Heart position is provided with circular port, and the looping pit both sides of sealing ring (1) are connected to a connecting cylinder for being used to insert in pipeline
(2), sealing ring (1) is provided with some bolt through-holes (3), and the both sides of bolt through-hole (3) are connected to one and are used for insertion
The bolt hole connecting cylinder (4) of blue valve snail keyhole, bolt hole connecting cylinder (4) are cylinder, and the stage casing internal diameter of bolt through-hole (3) is big
Internal diameter in bolt through-hole (3) both ends.
The sealing ring (1), connecting cylinder (2), bolt hole connecting cylinder (4) are integrally formed setting.
A metal support chip (6), shape and the sealing ring (1) of metal support chip (6) are provided with the sealing ring (1)
Form fit set.
Thickening washer (7) is provided with the outside of the sealing ring (1), the thickness of thickening washer (7) is more than sealing ring (1)
Thickness.Layer of silica gel (8) is provided with the thickening washer (7).
In the technical scheme of the application, add for inserting the connecting cylinder in pipeline (2) and for inserting flange valve snail
The bolt hole connecting cylinder (4) of keyhole, so when sealing gasket is placed, it can be connected by the way that connecting cylinder (2) grafting is entered into ring flange
Pipeline, then by bolt hole connecting cylinder (4) insert flange valve snail keyhole, the position of flangeseal pad can thus be entered
Row is positioned and fixed, and prevents sealing gasket from putting partially and causing the bad situation of sealing effectiveness to occur.And by bolt hole connecting cylinder
(4) after inserting flange valve snail keyhole, bolt passes through bolt through-hole (3).Because the stage casing internal diameter of bolt through-hole (3) is more than bolt mistake
The internal diameter at hole (3) both ends, when bolt passes through bolt through-hole (3), bolt can extrude bolt hole company at bolt through-hole (3) both ends
Connect cylinder (4) so that the outer wall extruding flange valve snail keyhole inwall of bolt hole connecting cylinder (4), carried by increasing contact seal pressure
Sealing effectiveness at high bolt hole.The thickness of thickening washer (7) is more than the thickness of sealing ring (1), so in two ring flanges pair
After connecing, thickening washer (7) is squeezed rear internal layer of silica gel (8) and is squeezed so that thickening washer (7) and ring flange connect
Touch pressure increase, the seal contact pressure of increase thickening washer (7) and ring flange, further increases sealing effectiveness.
Certainly, it is to limitation of the present utility model that described above, which is not, and the utility model is also not limited to the example above, this
The those of ordinary skill of technical field, in essential scope of the present utility model, the variations, modifications, additions or substitutions made, all
