Abstract
The utility model discloses a twist box -like novel flange, wherein, the flange includes first ring flange, second ring flange, first ring flange center is equipped with first through -hole, first through -hole inner wall is equipped with the internal thread structure, second ring flange center is equipped with the second through -hole, follows second through -hole edge axial direction extends and forms the annular arch, the protruding lateral wall of annular is equipped with the external screw thread structure, first ring flange and second ring flange can pass through the annular protruding with first through -hole is twisted and is closed the fastening. The utility model provides a traditional flange have that the leakproofness is relatively poor, sealed fills up perishable, the short scheduling problem of life.
Description
Technical field
The utility model relates to flange field, and particularly one screws up formula novel flange.
Background technique
Flange, the again blue flange disk of call or bead.Flange is interconnective part between pipe and pipe, for the connection between pipe end; Also the flange that the equipment that is used in is imported and exported is had, for the connection between two equipment, as speed reducer flange.Flange joint or flanged joint, refer to and be interconnected releasable connection as one group of combined sealing structure by flange, pad and bolt three.Piping flange means the flange of pipe arrangement in tube equipment, is used in import and export flange equipment meaning equipment.Perforation on flange, bolt makes two flanges be close to, and uses liner containment between flange.There is the problems such as sealing is poor, sealing gasket is perishable, working life is shorter in traditional flange.
Model utility content
Technical problem to be solved in the utility model is to provide one and screws up formula novel flange, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technological scheme: one screws up formula novel flange, wherein, described flange comprises the first flange plate, second flange plate, described first flange disk center is provided with the first through hole, described first through-hole wall is provided with female thread structure, described second flange plate center is provided with the second through hole, annular protrusion is extended to form along described second through hole edge axial direction, described annular protrusion outer side wall is provided with external thread structure, described first flange plate and the second flange plate can screw up fastening by described annular protrusion and described first through hole.
Preferably, described first flange plate is provided with the corresponding groove in position with the second flange plate surface of contact, is provided with seal ring in described groove.
Preferably, described first flange plate and described second flange plate are provided with screw hole, and described first flange plate and described second flange plate lock fastening nuts by locking nut through described screw hole.
Preferably, described seal ring and the first flange plate and the second flange plate surface of contact scribble sealer.
Preferably, described sealer is polyurethane sealant.
The beneficial effect of above technological scheme is adopted to be: the utility model provides one to screw up formula novel flange, wherein, described flange comprises the first flange plate, second flange plate, described first flange plate and the second flange plate can screw up fastening by described annular protrusion and described first through hole, greatly strengthen the tightness of flange, described first flange plate is provided with the corresponding groove in position with the second flange plate surface of contact, seal ring is provided with in described groove, described seal ring and the first flange plate and the second flange plate surface of contact scribble sealer, further increase the tightness of flange, simultaneously because flange plate is fastening by screwing up, material in its pipeline is difficult to invade seal ring, avoid seal ring Long contact time material and corrode, thus affect the tightness of flange, described first flange plate and described second flange plate are provided with screw hole, described first flange plate and described second flange plate lock fastening nuts by locking nut through described screw hole, strengthen its sealing.
