Description

Technical Field

[0001] This utility model relates to the field of flange technology, and in particular to a flange that is easy to install. Background Technology

[0002] A flange, also called a flange plate, is a part used to connect shafts. It is usually used for connecting pipe ends, and flanges are also used on equipment inlets and outlets for connecting two pieces of equipment.

[0003] For example, Chinese patent CN222416507U discloses a flange that is easy to install, including a flange body, a flange groove opened at an equal angle on the edge of the flange body, a rubber mating sleeve for connection, a rubber sealing sleeve, the rubber sealing sleeve is inserted into the inside of the flange body, and a sealing ring is fitted on the outer surface of the rubber sealing sleeve, and the sealing ring is tightly fitted between the flange body and the rubber mating sleeve, and an anti-loosening mechanism is symmetrically arranged on the left and right sides of the connecting screw, and the anti-loosening mechanism is used to lock and limit the fixing nut.

[0004] When using flanges to connect piping systems, the connection and sealing of the pipes are achieved by fixing two flanges with multiple bolts and adding a sealing gasket in between. However, in actual installation, the existing flange installation has many inconveniences. When aligning the bolt holes, the flanges are heavy and it is difficult to align them accurately by manual operation. This not only consumes a lot of time and manpower, but also easily leads to deviations, resulting in low installation efficiency. Secondly, relying solely on nuts for fixing results in poor tightness of the flange after installation. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a flange that is easy to install.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flange assembly for easy installation, comprising two opposing flanges, with multiple through holes arranged in a ring array on one side of each flange, multiple guide posts evenly distributed on one flange edge near the other flange, and guide holes corresponding to the guide posts on the other flange, multiple slots evenly distributed on the opposite outer edges of the two flanges, and multiple fixing components corresponding to the slots on the flanges, the fixing components comprising a fixing plate and a screw, two side plates symmetrically welded to both ends of the fixing plate, and a locking block fixedly installed on the opposite side of the two side plates, one end of the locking block engaging with the slot, and mounting holes through one end of the two side plates, the two ends of the screw being inserted into the through holes, and the two ends of the screw passing through the mounting holes on both sides and threaded with threaded rings.

[0007] Preferably, curved plates are symmetrically welded on both sides of the fixing plate, and a sealing gasket is fixedly connected to the side of the curved plate closest to the flange.

[0008] Preferably, one end of the guide post is inserted into the guide hole, the guide post is in the shape of a polygonal column, and the axis of the guide post is parallel to the axis of the flange.

[0009] Preferably, annular grooves are provided on opposite sides of the two flanges, and a movable ring is slidably connected inside the annular grooves.

[0010] Preferably, multiple springs are provided between the annular groove and the movable ring, and a sealing rubber ring is fixedly connected to the side of the movable ring away from the springs.

[0011] Preferably, the mounting hole adopts a stepped hole design, with a small diameter hole at the end closer to the locking block and a large diameter hole at the end farther from the locking block. The diameter of the large diameter hole is larger than the diameter of the threaded ring, and the diameter of the small diameter hole is matched with the diameter of the screw.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the flange incorporates a fixing component. The two flanges are initially positioned using guide posts and guide holes, guiding them to quickly align and reducing the difficulty of aligning the through holes. The fixing component then uses locking blocks and slots to pre-tighten the two flanges, achieving rapid pre-tightening and preventing misalignment during subsequent bolt installation. This improves installation accuracy and efficiency, while also reducing the need for multiple people to work together. Finally, the flanges are installed by fixing them with bolts and threaded rings. This method allows for quick alignment and initial fixing of the two flanges, eliminating the need for extensive time and effort to manually align the bolt holes, significantly shortening installation time. Furthermore, the combination of multiple fixing methods enhances the tightness of the flange during installation.

[0014] 2. In this utility model, by adding a movable ring and a sealing rubber ring on opposite sides of the two flanges, the movable ring and the sealing rubber ring can be pressed together by the elastic force of multiple springs. At the same time, the multiple sealing gaskets of the fixing component can seal the gaps on the outside of the flange, thereby improving the sealing performance and reliability of the flange connection and reducing the risk of pipeline leakage.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-5As shown, this utility model provides a flange that is easy to install, including a flange assembly 1. The flange assembly 1 includes two flanges 11 arranged opposite each other. Multiple through holes 12 are arranged in a ring array on one side of the two flanges 11. Multiple guide posts 16 are evenly arranged on one side edge of one flange 11 near the other flange 11. Guide holes 14 are opened on the other flange 11 at the positions corresponding to the guide posts 16. Multiple slots 13 are evenly arranged on the outer edges of the opposite sides of the two flanges 11. Multiple fixing components 2 are arranged at the positions of the multiple slots 13 on the flanges 11. The fixing components 2 include fixing plates 21 and screws 27. Two side plates 2 are symmetrically welded to both ends of the fixing plates 21. 2. Two side plates 22 are fixedly installed with locking blocks 24 on opposite sides. One end of the locking block 24 is engaged with the locking groove 13. One end of the two side plates 22 is provided with a mounting hole 26. The two ends of the screw 27 are inserted into the through hole 12. The two ends of the screw 27 pass through the mounting holes 26 on both sides and are threadedly connected with threaded rings 28. One end of the guide post 16 is inserted into the guide hole 14. The guide post 16 is polygonal column-shaped, and the axis of the guide post 16 is parallel to the axis of the flange 11. The mounting hole 26 adopts a stepped hole design. The end near the locking block 24 is a small diameter hole, and the end away from the locking block 24 is a large diameter hole. The diameter of the large diameter hole is larger than the diameter of the threaded ring 28, and the diameter of the small diameter hole is matched with the diameter of the screw 27.

[0024] The specific settings and functions of this embodiment are described below: When installing the flange assemblies 1 on both the left and right sides, as follows: Figure 1 and Figure 2 As shown, the left flange assembly 1 can be fixed first, and the right flange assembly 1 can be aligned and brought close to the left flange assembly 1. Multiple guide posts 16 are evenly arranged on one side of the right flange 11. The outer surface of the guide posts 16 is smooth to reduce friction when mating with the flange 11. The left flange 11 has guide holes 14 at the positions corresponding to the guide posts 16. The diameter of the guide holes 14 is slightly larger than the diameter of the guide posts 16. The two are fitted with a clearance, so that the guide posts 16 can be smoothly inserted into the guide holes 14, which plays a preliminary positioning role. When installing the flange, the two flanges 11 are brought close together, and the guide posts 16 can automatically insert into the guide holes 14, guiding the two flanges 11 to quickly align, reducing the difficulty of aligning the through holes 12 and improving the installation efficiency.

[0025] After initial positioning, the multiple through holes 12 of the two flanges 11 are paired and correspond to each other (the through holes 12 have the same diameter, and the axes of the two through holes 12 are on the same axis). The fixing plate 21 is placed outside the slot 13 of the flange 11, and the two end blocks 24 of the fixing plate 21 are aligned with the slot 13. The fixing plate 21 is pushed and the blocks 24 are engaged in the slot 13. The multiple fixing components 2 are then pre-tightened by snapping (the blocks 24 are engaged and fixed with the slot 13), thereby pre-tightening the two flanges 11 together and achieving rapid pre-tightening of the flanges 11 to prevent misalignment of the two flanges 11 during the subsequent installation of the bolts 27. At this time, the two mounting holes 26 of the fixing components 2 and the two corresponding positions are... The axes of the through holes 12 are on the same axis. The screw 27 is inserted into the mounting hole 26 on one side of the fixing component 2. After the screw 27 passes through the through holes 12 of the left and right flanges 11, it is then passed out through the mounting hole 26 on the other side. Then the threaded ring 28 is rotated so that the threaded ring 28 is threadedly connected to both ends of the screw 27, which facilitates the quick installation and fixing of the left and right flanges 11, making the two flanges 11 tightly connected and completing the flange installation. At the same time, this design allows the end of the screw 27 and the threaded ring 28 to be hidden in the large-diameter hole of the mounting hole 26, preventing the end of the screw 27 and the threaded ring 28 from protruding from the surface of the side plate 22. This not only makes the flange more aesthetically pleasing, but also prevents the threaded ring 28 from being damaged by collision during transportation or use.

[0026] This flange incorporates a fixing component 2. The two flanges 11 are initially positioned using guide posts 16 and guide holes 14. The fixing component 2 then pre-tightens the two flanges 11 by engaging with a locking block 24 and a locking groove 13, preventing misalignment of the two flanges 11 during the subsequent installation of the bolts 27. This improves the accuracy and efficiency of the installation and reduces the need for multiple people to work together. Finally, the flanges 11 are installed by threading the bolts 27 and threaded rings 28. This method allows for quick alignment and initial fixing of the two flanges 11 without the need for extensive manual alignment of the bolt holes, significantly shortening the installation time. Furthermore, the combination of multiple fixing methods enhances the tightness of the flange during installation.

[0027] Example 2: Figure 2 , Figure 4 and Figure 5 As shown, arc-shaped plates 23 are symmetrically welded on both sides of the fixed plate 21, and a sealing gasket 25 is fixedly connected to the side of the arc-shaped plate 23 near the flange 11. Annular grooves 15 are opened on opposite sides of the two flanges 11, and a movable ring 18 is slidably connected inside the annular groove 15. Multiple springs 17 are provided between the annular groove 15 and the movable ring 18, and a sealing rubber ring 19 is fixedly connected to the side of the movable ring 18 away from the spring 17.

[0028] The overall effect of this embodiment is that by adding a movable ring 18 and a sealing rubber ring 19 to the opposite sides of the two flanges 11, the movable ring 18 and the sealing rubber ring 19 can be pressed together by the elastic force of multiple springs 17. At the same time, the multiple sealing gaskets 25 of the fixing assembly 2 can seal the gaps on the outside of the flanges 11, thereby improving the sealing performance and reliability of the flange connection and reducing the risk of pipeline leakage.

[0029] The usage method and working principle of this device are as follows: Figure 1 and Figure 2 As shown, multiple guide posts 16 are evenly arranged on one side of the right flange 11, and guide holes 14 are opened on the left flange 11 corresponding to the positions of the guide posts 16. When installing the flanges, the two flanges 11 are brought close together, and the guide posts 16 can automatically insert into the guide holes 14, guiding the two flanges 11 to quickly align, reducing the difficulty of aligning the through holes 12 and improving installation efficiency. After completing the initial positioning, the fixing plate 21 is placed outside the slot 13 of the flange 11, and the two end blocks 24 of the fixing plate 21 are aligned with the slot 13, pushing the fixing plate 21 to the side. Fix plate 21 and engage the locking block 24 in the locking groove 13. Sequentially tighten multiple fixing components 2 by engaging them to pre-tighten the two flanges 11 together. Then, insert screw 27 into the mounting hole 26 on one side of the fixing component 2. After the screw 27 passes through the through holes 12 of the two flanges 11, it exits through the mounting hole 26 on the other side. Then rotate the threaded ring 28 so that the threaded ring 28 is threaded to both ends of the screw 27, which facilitates the quick installation and fixing of the two flanges 11, thus completing the flange installation.

[0030] The flange is designed with an added fixing component 2. The two flanges 11 are initially positioned by the guide post 16 and the guide hole 14. The fixing component 2 then pre-tightens the two flanges 11 by engaging the locking block 24 and the locking groove 13 to prevent misalignment of the two flanges 11 during the subsequent installation of the screw 27, thereby improving the accuracy and efficiency of the installation. Finally, the flanges 11 are installed by fixing them with the screw 27 and the threaded ring 28. This design allows for quick alignment and initial fixing of the two flanges 11, shortening the installation time. At the same time, the combination of multiple fixing methods enhances the tightness of the flange during installation.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
