Description

Technical Field

[0001] This utility model relates to the field of pipeline installation, and more specifically, to a flanged pipeline that is easy to connect. Background Technology

[0002] Flange pipes are a widely used pipe connection method in the industrial field. Traditional flange pipes usually use bolted connections, where two opposing flanges are fastened together with bolts, and a sealing gasket is placed in between to achieve a seal. Although this connection method is reliable, it has the problem of alignment difficulties: the bolt hole positions need to be precisely aligned, otherwise installation is impossible, which increases the difficulty of installation and the technical requirements for operators. Utility Model Content

[0003] The present invention aims to provide a flanged pipe that is easy to connect, so as to solve the problem of difficult alignment of flanged pipes in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a flanged pipe that is easy to connect is provided, characterized in that it includes: a main flange and a secondary flange, and a pipe connected between the main flange and the secondary flange. The end face S1 of the main flange is provided with a plurality of grooves, all of which are located outside the bolt mounting holes. The end face S2 of the secondary flange is provided with a plurality of protrusions, the protrusions and the grooves being mutually adapted to each other, wherein the grooves form a locking mechanism for the protrusions to prevent the protrusions from moving within the grooves.

[0005] Furthermore, the groove includes a first surrounding surface, a second surrounding surface, a first curved surface, and a bottom surface. The projections of the plurality of first curved surfaces on the end face S1 coincide with the outer contour of the end face S1. The projections of the plurality of first surrounding surfaces on the end face S1 are located in the radial direction of the main flange. The projections of the plurality of second surrounding surfaces on the end face S1 are perpendicular to the projections of the first surrounding surfaces within the end face S1.

[0006] Furthermore, a guide slope is provided between two adjacent grooves on the main flange, and the guide slope is inclined in a clockwise direction.

[0007] Furthermore, the guiding slope is a curved surface.

[0008] Furthermore, the protrusion includes a third surrounding surface, a fourth surrounding surface, a second curved surface, and a top surface. The projections of the plurality of second curved surfaces on the end face S2 coincide with the outer contour of the end face S2. The projections of the plurality of third surrounding surfaces on the end face S2 are located in the radial direction of the auxiliary flange. The projections of the plurality of fourth surrounding surfaces on the end face S2 are perpendicular to the projections of the third surrounding surfaces within the end face S2. The plane containing the top surface is parallel to the plane containing the bottom surface when the main and auxiliary flanges are joined.

[0009] Furthermore, the number of grooves is at least 8, and the number of protrusions is the same as the number of grooves.

[0010] In the technical solution of this utility model, the matching protrusions and grooves ensure that the main and auxiliary flanges do not move relative to each other after they are fitted together, so that the aligned mounting holes do not shift and the alignment is accurate, reducing the difficulty of flange pipe installation.

The illustrative embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an undue limitation of the present invention. In the drawings:

[0012] Figure 1 A schematic diagram of a main flange for a flanged pipe that is easy to connect according to the present invention is shown;

[0013] Figure 2 It shows Figure 1 A schematic diagram of the secondary flange of a flanged pipe. Detailed Implementation

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] See also Figures 1 to 2 As can be seen from the figure, the flange pipe for easy connection in this embodiment includes: a main flange 10 and a secondary flange 20, and a pipe connected between the main flange 10 and the secondary flange 20. The end face S1 of the main flange 10 is provided with a plurality of grooves 11, all of which are located outside the bolt mounting holes. The end face S2 of the secondary flange 20 is provided with a plurality of protrusions 21, which are adapted to each other. The grooves 11 form a locking mechanism for the protrusions 21 to prevent the protrusions 21 from moving within the grooves 11.

[0016] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: the matching protrusions 21 and grooves 11 ensure that the main and auxiliary flanges do not move relative to each other after fitting, the aligned mounting holes do not shift, and the alignment is accurate, reducing the difficulty of flange pipe installation.

[0017] Preferably, the groove 11 on the main flange 10 ( Figure 1The shaded area in the image is formed by the first surrounding surface, the second surrounding surface, the first curved surface, and the bottom surface. Correspondingly, the protrusion 21 on the secondary flange 20 is formed by the corresponding third surrounding surface, the fourth surrounding surface, the second curved surface, and the top surface. This arrangement allows the shape of the protrusion 21 on the secondary flange 20 to perfectly match the shape of the groove 11 on the main flange 10. When the protrusion 21 is fully inserted into the groove 11, it is completely locked inside the groove 11, and no relative displacement occurs between the main and secondary flanges. In this embodiment, multiple grooves 11 are evenly distributed along the circumference of the main flange 10, and the projection of the first curved surface of all grooves 11 onto the end face S1 of the main flange 10 coincides with the outer contour of the end face S1. The projections of multiple first surrounding surfaces onto the end face S1 are all located in the radial direction of the main flange 10, and the projection of the second surrounding surface of each groove 11 onto the end face S1 is perpendicular to the projection of its own first surrounding surface onto the end face S1. Multiple protrusions 21 ( Figure 2 The shaded areas are evenly distributed along the circumference of the sub-flange 20. The projection of the second curved surface of all the protrusions 21 onto the end face S2 of the sub-flange 20 coincides with the outer contour of the end face S2. The projections of multiple third surfaces onto the end face S2 are all located in the radial direction of the sub-flange 20. The projection of the fourth surface of each protrusion 21 onto the end face S2 is perpendicular to the projection of its own third surface onto the end face S2.

[0018] On the main flange 10, a rib-like structure is formed between the two grooves 11. The end faces of the multiple rib-like structures are all inclined, and the inclination angle and direction are the same. In this embodiment, the rib structure can be inclined clockwise to form a guide slope 12. When the main and auxiliary flanges are connected, if the protrusion 21 cannot be directly aligned with the groove 11, the protrusion 21 presses against the guide slope 12. At this time, rotating the auxiliary flange 20 clockwise will gradually push the protrusion 21 into the groove 11 along the slope. In a preferred embodiment, the guide slope 12 is curved, which can more easily guide the protrusion 21 into the groove 11. After the protrusion 21 enters the groove 11, the main and auxiliary flanges can no longer rotate relative to each other. At this time, the bolt holes on the main and auxiliary flanges are completely aligned, which can facilitate the subsequent installation of bolts.

[0019] In this embodiment, there are 10 grooves 11 and 10 protrusions 21. The design can be adjusted according to the actual situation in production. Setting the number to 10 can increase the contact area between a single groove 11 and protrusion 21 and facilitate processing. If the number is too small, the projection length of the second circumference of the groove 11 in the end face S1 will be too long, increasing the radial length of the main flange 10 and making it unsuitable for practical application. Although designing too many numbers will reduce the projection length of the second circumference in the end face S1, the processing is cumbersome and not conducive to the production of the flange.

[0020] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
