In the description of the present application, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., it indicates that the orientation and positional relationship shown in the drawings are based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be construed as limiting the specific scope of protection of the present application.

It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

The terms "comprises," "comprising," and "having," and any variations thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The present application is further described with reference to the accompanying drawings:

as shown in fig. 1 to 4, a preferred embodiment of the present application includes a flange main body 1, a flange hole 11 is formed in the flange main body 1, the flange hole 11 is used for connecting with a pipeline, an installation groove 111 is formed in the flange hole 11, a sealing ring 112 is embedded in the installation groove 111, the sealing ring 112 is connected with the pipeline sleeve along with the flange main body 1, sealing between the pipeline and the flange can be achieved, in order to increase sealing performance of the sealing ring 112, an inner diameter of the sealing ring 112 needs to be smaller than a diameter of the flange hole 11, so that the sealing ring 112 can be closer to the pipeline, because the inner diameter of the sealing ring 112 is smaller, it is possible that the pipeline is difficult to be installed in the flange hole 11, so installation inclined planes 1121 inclined to the outside are provided on two sides of the inner diameter of the sealing ring 112, so that the pipeline can pass through the sealing ring 112 more easily.

A plurality of mounting holes 12 are arranged around the flange hole 11 at equal intervals, bolts can be mounted in the mounting holes 12, two flanges are connected, a plurality of placing grooves 13 are radially formed in the flange main body 1, the placing grooves 13 and the mounting holes 12 are arranged in a one-to-one matching mode, the placing grooves 13 are communicated to the outside from the side face of the flange main body 1, detachable fixing blocks 2 are arranged in the placing grooves 13, the fixing blocks 2 can be inserted into the placing grooves 13 from the outer side of the flange main body 1, each fixing block 2 is provided with a top column 21, the length of each top column 21 is slightly longer than the distance from the corresponding fixing block 2 to a sealing ring 112, the top columns 21 can extend into the mounting grooves 111 to be in contact with the sealing rings 112, the sealing rings 112 have elasticity, and can apply pressure to the top columns 21 and drive the fixing blocks 2 to be pushed out; offer the through-hole 22 of cooperation mounting hole 12 on fixed block 2, align mounting hole 12 with through-hole 22, then when using the bolt to fix, fore-set 21 can inwards extrude sealing ring 112, realize fixed and the extrusion to sealing ring 112, increase the stability and the leakproofness of connecting between pipeline and the flange, sealing ring 112 preferably uses the rubber ring, rubber ring matter is soft, the extrusion between other spare parts of adaptation that can be better, easy to assemble.

The fixing block 2 may be in various shapes, but the top pillar 21 is suitable for using a cylindrical shape, so as to prevent an excessive machining error between the top pillar 21 and the fixing block 2, and prevent the top pillar 21 from smoothly extending into the installation groove 111 to contact with the sealing ring 112.

The top of the top pillar 21 is provided with a tip cone 211, so that the top pillar 21 can be extruded into the sealing ring 112 and is clamped and fixed with the sealing ring 112, and the sealing performance and the stability of the sealing ring 112 are further improved.

As shown in fig. 5, a screw thread is provided in the mounting hole 12, and the inner wall of the through hole 22 is set as a smooth surface, because the mounting hole 12 and the through hole 22 are not on the same component, if the mounting hole 12 and the through hole 22 are both provided with screw threads, the bolt may not be smoothly mounted because the screw threads cannot be paired, and the through hole 22 only needs to play a role of positioning, so that the inner wall of the through hole 22 is set as the smooth surface, and the processing difficulty is reduced.

The diameter of the top pillar 21 needs to be smaller than the width of the sealing ring 112, if the diameter of the top pillar 21 is larger than the width of the sealing ring 112, the sealing ring 112 cannot be effectively fixed, or a gap is generated between the sealing ring 112 and the top pillar 21, so that the stability and the sealing performance are reduced; the width of fixed block 2 need not be less than the diameter of fore-set 21, because fixed block 2 inserts in the standing groove 13, if the diameter of fore-set 21 is greater than the width of fixed block 2, for fore-set 21 can pass through smoothly, fixed block 2 will leave the gap all around, can reduce the holistic leakproofness of flange.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed. The scope of protection claimed by this application is defined by the following claims and their equivalents.
