Abstract
The utility model discloses a flange pipeline coupling device, which comprises a flange base (1), a coupling gland bush (3), a rubber packing ring (4) and a coupling screw bolt (2), wherein one end of the flange base (1) is provided with a flange structure, the other end which is matched with the lower end of the rubber packing ring (4) is provided with an oblique angle of 45 degrees, the lower end of the coupling gland bush (3) is matched with the upper end of the rubber packing ring (4), the axial cords of the flange base (1), the rubber packing ring (4) and the coupling gland bush (3) are overlapped, and the flange base (1), the rubber packing ring (4), and the coupling gland bush (3) are coupled into a whole through the coupling screw bolt (2). Compared with an existing technique, the coupling device is characterized in that the coupling device has simple and novel structure and the use is environmental friendly. The utility model has the advantages of higher installing efficiency and more reliable sealing performance in coupling special shaped and nonstandard pipelines through inserting directly.
Description
Technical field
The utility model relates to a kind of flanged pipe coupling arrangement, particularly the reducing in the certain limit, the flanged pipe coupling arrangement of non-standard pipeline.
Background technique
In pipeline is installed, utilize flanged joint or flange bellmouth joint etc. that pipeline is docked usually.General flanged pipe coupling arrangement is at present, one end and the pipeline upper flange of flange are fixedly connected, the other end passes through fixedly, and rubber seal is connected with the pipeline straight cutting, rubber seal is installed in the fixedly bellmouth of coupling, itself and the sealing of inserting pipeline are that the resiliently deformable by rubber realizes.The rubber seal position of common flange joiner only connects with a kind of fixing straight tube, and this kind fixedly cast connects, and is subjected to the boundary dimension restriction ratio of connection pipe fitting more outstanding in actual pipe connects.Particularly in particular cases bigger at casting pipe size scattered error, fixedly the sealability of rubber seal flange joiner is not good for it, is subjected to dimensional accuracy, the degree of finish at coupling bellmouth position; The dimensional accuracy of rubber seal; Influence such as institute's connection pipe fitting outside dimension precision, degree of finish is more outstanding.
The model utility content
Technical problem to be solved in the utility model is the pipe fitting of certain limit size, still has the flanged pipe coupling arrangement of excellent sealing performance.
The technological scheme that the utility model solved is: the flanged pipe coupling arrangement, comprise flange base, joiner gland, rubber seal, attachment bolt, one end of described flange base is a flange arrangement, the other end that matches with the rubber seal lower end has 45 degree oblique angles, match with the rubber seal upper end in the lower end of joiner gland, the dead in line of flange base, rubber seal, joiner gland, flange base, rubber seal, joiner gland join together by attachment bolt.
For the seal of reinforcing flange joiner, the inner and outer surface of described rubber seal is provided with the zigzag fashion annular projection.
In order to reduce the weight of flange joiner, under the prerequisite that guarantees the pipeline seal, also can go material processed to the part of flange base.
The locating slot of described flange base is an elongated slot.
Connecting structure of the present utility model is simple, and under the prerequisite that guarantees coupling intensity, the joiner gland structure designs between 7～10mm, to reduce the deadweight of connected body; Ring is designed to the zigzag fashion ring-type in the rubber seal, and this helps the insertion and the fitted seal of pipe fitting; Glue seal ring exterior angle radius of arc 25mm, and be linear and contact with the flange bases at 45 degree oblique angles, help the rubber seal axially loaded, the radial contraction distortion, behind glue seal ring axial compression, can produce the displacement amount of 20～30mm diametrically, thereby the pipe that farthest adapts to various criterion scope pipe fitting connects and seal request.
The utility model compared with prior art has the characteristics of novelty simple in structure, use environmental protection, and in abnormity, nonstandard pipeline straight cutting connected, this structural member had more installation efficiency height, the reliable advantage of sealability especially.

Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Embodiment 1:
As shown in Figure 1, the utility model comprises flange base 1, joiner gland 3, rubber seal 4, attachment bolt 2, one end of described flange base 1 is a flange arrangement, be used for being connected by bolt with corresponding piping flange or valve flange, with rubber seal, the other end that matches in 4 lower ends has 45 degree oblique angles, match with rubber seal 4 upper ends in the lower end of joiner gland 3, the dead in line of flange base 1, rubber seal 4, joiner gland 3, flange base 1, rubber seal 4, joiner gland 3 join together by attachment bolt 2.
Embodiment 2: shown in Fig. 2-3, for the seal of reinforcing flange joiner, the inner and outer surface of described rubber seal 4 is provided with the zigzag fashion annular projection.
Embodiment 3: shown in Fig. 4,5, in order to have reduced the joiner deadweight, reach effect attractive in appearance simultaneously, 5 positions of flange base 1 are carried out part and are gone material processed, and locating slot 6 is an elongated slot.
Insert rubber seal 4 ends of flange joiner when pipe fitting after, pass through swivel nut, joiner gland 3 is done axial displacement, rubber seal 4 is through 45 degree straight oblique angle extrusion-deformations, thereby make rubber seal 3 produce radial contraction, rubber seal 3 internal diameters and pipe fitting external diameter are closely cooperated, thereby reach the purpose of sealed against leakage.
