Abstract
The utility model relates to a flange for pipelines, particularly a double ring type locking quick-mounting flange for pipelines, which is composed of a flange plate, a pressure ring, a clamping ring, a support ring and sealing rings. The pressure ring (2), the clamping ring (3), and the support ring (4) are arranged in a large cylindrical hole of the flange plate (1); an internal conical surface of the pressure ring (2) matches with an external conical surface of the clamping ring (3); the sealing rings (5) are arranged on the ends of the flange plate (1) and the support ring (4); two flange plates are connected with bolts (7). The utility model has the advantages that the flange plates are fixed on the ends of pipes without welding technology, and the pipelines can be connected by flanges quickly with common pipelining tools.
Description
The utility model relates to piping flange, particularly a kind of dicyclic locking fast-assembling piping flange.
The above pipeline of inside nominal diameter 50mm adopts the flange mode to connect more in the prior art, and flange plate and the combination of the many employing welding manners of combining of pipe termination.Welding technique is strong, the equipment heaviness.And some tubing is welded with difficulty because of the material relation, moulds metal tube etc. as aluminum pipe, lining, just can not use welding flange to realize that pipeline connects.
The purpose of this utility model is: a kind of dicyclic locking fast-assembling piping flange is provided, need not to adopt welding procedure that flange plate is fixed in the pipe termination, use piping erection instrument commonly used, can carry out flange to pipeline fast and connect.
Formation of the present utility model: form by flange plate, pressure ring, snap ring, support ring, seal ring, pressure ring (2), snap ring (3) and support ring (4) are installed in the big column hole of flange plate (1), the internal conical surface of pressure ring (2) cooperates with the outer conical surface of snap ring (3), at flange plate (1) and support ring (4) termination seal ring (5) is installed, is connected by bolt (7) between two flange plate.Flange plate (1) is the combination of disk and cylinder, and cylinder end has small stair (8) entad, and equally distributed four cylindrical holes (9) are arranged on the disk, and several circular groove (10) is arranged on the end face.Pressure ring (2) is a closed circle, and inwall has conical surface (11).Snap ring (3) is for being provided with the annulus of opening (12), and outer wall has conical surface (13), and inwall has several pointed tooth bars (14) along the circumferential direction.Support ring (4) is cylindric, and a port has internal conical surface (15).Seal ring (5) is that disk and cross section are the annulus combination of right-angled trapezium (17), and there is stepped shaft endoporus (16) centre.Can will keep the conical surface pressure ring (2) in opposite directions and the integral body of snap ring (3) to turn 180 ° of installations.
Compared with the prior art, the utility model in the pipe termination, but adopts the dicyclic locking mode that flange and pipe are combined into one without the welding procedure mounting flange.When the locking pipe, adopt pointed tooth to embed tube wall, utilize the shearing drag to guarantee locking effect, pressure ring is under the reach of flange plate promotes, the male cone (strobilus masculinus) relative movement of its inner conical surface and snap ring, snap ring is firmly fixing, make the snap ring tooth bar not produce displacement, the sealing of this flange adopts the pipe end face seal to combine with the tube wall face seal, support ring provides the seam position of seal ring, and increased flange plate and pipe effectively combine length, thereby make the pipe have good lateral stability.Because it is flange is fixed in the pipe termination without welding procedure, therefore quick and easy for installation.This flange can be connected with the flange of other kinds easily.

Embodiment of the present utility model: as shown in Figure 1, with flange plate (1), pressure ring (2), snap ring (3), be enclosed within successively on the pipe (6), with pipe cutter specified position cutting on pipe (6) outer wall, the bar number of groove and the degree of depth of groove are identical with the internal tooth (14) of snap ring (3), the tooth bar of snap ring (3) (14) is put into groove, press pressure ring (2), and support ring (4), seal ring (5) be enclosed within the pipe termination successively, push to flange plate (1), connect another flange plate with bolt (7), tighten bolt, promptly finish the connection of this flange plate.
Shown in accompanying drawing 2, accompanying drawing 3, flange plate (1) is the combination of disk and cylinder, and cylinder end has small stair (8) entad, and equally distributed four cylindrical holes (9) are arranged on the disk, and end face has several circular groove (10).
Shown in accompanying drawing 4, accompanying drawing 5, pressure ring (2) is a closed circle, and inwall has conical surface (11).
Shown in accompanying drawing 6, accompanying drawing 7, snap ring (3) is for being provided with the annulus of opening (12), and outer wall has conical surface (13), and inwall has several pointed tooth bars (14) along the circumferential direction.
Shown in accompanying drawing 8, accompanying drawing 9, support ring (4) is cylindric, and a port has internal conical surface (15).
Shown in accompanying drawing 10, accompanying drawing 11, seal ring (5) is that disk and cross section are the annulus combination of right-angled trapezium (17), and there is stepped bore (16) centre.
