Description
Technical field
The utility model relates to a kind of flange arrangements, more particularly, to a kind of High-sealing-performflange flange structure.
Background technique
Flange arrangement is the structure of common connection cylindrical workpiece, the pad for generally including two ring flanges and being clipped in the middle
Piece, two ring flanges are locked by bolt.For oscillation intensity and the higher working environment of frequency, the assembly of ring flange and gasket
It is easy gasket offset, influences the sealing performance of flange arrangement.
Utility model content
The purpose of this utility model is to provide the flange arrangements that one kind can reduce the caused sealing performance decline of vibration.
The purpose of this utility model is achieved through the following technical solutions: a kind of High-sealing-performflange flange structure, including overlapping
First flange disk and second flange disk, the edge of the first flange disk are provided with the first locking hole, the side of the second flange disk
Edge be provided with second locking hole Chong Die with the first locking hole, first flange disk and second flange disk by penetrate the first locking hole and
The bolt of second locking hole connects；It is provided with the first mounting hole in the middle part of the first flange disk, is provided in the middle part of the second flange disk
Second mounting hole Chong Die with the first mounting hole is additionally provided on the inside of first locking hole around the first recessed of the first mounting hole
Slot is additionally provided with the second groove around the second mounting hole on the inside of second locking hole；First groove and the second groove are opposite
Setting；It further include the ring elastic parts being installed between the first groove and the second groove；The first flange disk, second flange
Disk and ring elastic parts interference fit.
The first flange disk and second flange disk can be selected steel and be made up of processes such as punching press, CNC.Described first is recessed
Slot, the second groove can be by technological formings such as punching press, CNC on the surface of first flange disk and second flange disk.The annular
Elastic component can be selected any elastic material and be made, such as asbestos, rubber.The utility model is especially in first flange disk and second
The first groove, the second groove are opened up on the face of both ring flanges contact, and ring elastic parts are mounted on the first groove, second recessed
In slot.By ring elastic parts and the first groove, the triangular mutual cooperation of the second groove, increase first flange disk and the second method
Positional stability between blue disk avoids first flange disk and second flange disk and ring elastic parts from shifting because of vibration
Sealing performance is caused to decline.
Further, at least one buffering line of rabbet joint is had at the top and bottom of the ring elastic parts.
Since flange arrangement is usually used in the environment with certain reaction temperature, the buffering line of rabbet joint is especially arranged in ring elastic parts
The a degree of deformation generated with adapting to ring elastic parts in temperature change, to maintain ring elastic parts, first flange disk
Stable state between second flange disk.The top and bottom of ring elastic parts are arranged in the buffering line of rabbet joint, by the first groove, the
Two grooves are wrapped up, and the influence to product hermeticity energy can be reduced.
Further, its section of the buffering line of rabbet joint is U-shaped.
The buffering line of rabbet joint of channel section can avoid its bottom and form stress concentration point and ring elastic parts service life be caused to contract
It is short.
