[0001] The utility model relates to the technical field of flange plates, and particularly relates to a special pipeline sealing connection flange plate structure. Background Technique

[0002] The flange plate is simply called a flange, which is just a general term. Usually, it refers to a disc-shaped metal body with several fixing holes on its periphery for connecting other things. It is widely used in machinery. When making a flange connection for special pipelines, it is necessary to increase the sealing structure to ensure the sealing performance of the flange connection.

[0003] A special pipeline sealing connection flange plate structure is disclosed in the related technology (publication number: CN107965626A). The disclosed technical solution is as follows: A multi-layer sealing structure is arranged at the pipeline connection position, which makes the sealing performance of the parts more guaranteed during use, makes its safety more reliable during use, can make the service life of the pipeline longer, and has better stability during use.

[0004] In the above-mentioned disclosed technical solution, it is found that the following problems exist in the related technology: During the application of the flange plate, for some special pipelines, such as pipelines with oval interfaces, due to the control of the pipeline flow velocity, the pipeline opening is set to be oval, and the center of the conventional flange plate is circular. When docking with the pipeline, the sealing performance cannot be guaranteed. For this reason, we propose a new special pipeline sealing connection flange plate structure.

[0005] It should be noted that the information disclosed in the above background technical part is only used to strengthen the understanding of the background technical part of this application. Therefore, it may include prior art information that does not constitute known information to those of ordinary skill in the art. Content of the Utility Model

A pipeline outer wall clamping seat is arranged on the outer side of the elastic clamping seat, and the pipeline outer wall clamping seat is slidably arranged on the side wall of the flange plate. A distance adjusting component for adjusting the position of the pipeline outer wall clamping seat is arranged on the side wall of the flange plate, and a locking component is arranged on the distance adjusting component.

[0008] In the above technical solution, the distance adjustment component includes a rotating seat rotatably arranged on the side wall of the flange, and a pushing frame is installed through the rotating seat.

[0011] A mounting ear is slidably provided on the circumferential outer wall of the flange, and a position locking component is provided on the mounting ear.

[0012] The position locking assembly includes a transmission column that longitudinally penetrates the inner cavity of the mounting ear, a wedge-shaped slot is provided on the outer wall of the transmission column, a positioning bolt opposite to the wedge-shaped slot is threadedly connected to the side wall of the mounting ear, a socket is fixedly installed on the side wall of the mounting ear, a directional slide is embedded in the inner cavity of the socket, and an elastic member is provided between the directional slide and the bottom of the inner wall of the socket, and the slide is connected to the transmission column.

[0013] The clamping end of the positioning bolt and the wedge-shaped clamping groove is hemispherical.

[0014] A directional guide rod is fixedly mounted on the bottom of the directional slide, a directional guide groove opposite to the directional guide rod is formed at the bottom of the inner cavity of the socket, and the elastic member is sleeved on the outside of the directional guide rod.

[0015] A sealing gasket is embedded in the side wall of the flange.

[0018] 1. Move the pipe outer wall holders on both sides to the outer wall of the pipe through the distance adjustment component, and then lock the position of the pipe outer wall holder through the locking component. By adjusting the position of the pipe outer wall holders on both sides, it is suitable for pipes of different specifications, making it more convenient to connect the flange with the special pipe, thereby ensuring the applicability of the flange, avoiding gaps at the docking point, and then ensuring the sealing after the flange and the special pipe are connected.

[0019] II. When docking the flange with a special pipe interface, gather the two groups of elastic clamping seats on both sides of the flange holes to make the elastic clamping seats generate elastic force.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Next, in combination with specific implementation cases and attached Figures 1 - 6 The present invention will be further described, but the present invention is not limited to these embodiments.

[0032] A special pipe sealing connection flange structure includes a flange 1. Elastic clamping seats 2 are evenly and obliquely arranged on both sides of the flange hole of the flange 1, and the elastic clamping seats 2 on both sides are symmetrically arranged in an arc-shaped expansion. The center of the flange 1 is a flange hole, and auxiliary through holes are symmetrically opened on both sides of the flange hole, thereby ensuring the flow efficiency after the flange 1 is docked with the oval pipe opening. A plurality of elastic clamping seats 2 are arranged in an arc in sequence on both sides of the flange hole. The elastic clamping seats 2 are obliquely and fixedly installed on the surface of the flange 1, and the elastic clamping seats 2 expand outward while being arranged in an arc, that is, the arc-shaped seat groups formed by a plurality of elastic clamping seats 2 on both sides are symmetrically fixed on both sides of the central flange hole in an open form.

[0033] The elastic clamping seat 2 is made of an elastic material and is clamped on the inner wall of the butt joint pipe through elastic deformation during clamping. A pipe outer wall clamping seat 3 is arranged on the outer side of the elastic clamping seat 2, and the pipe outer wall clamping seat 3 is slidably arranged on the side wall of the flange 1. The two pipe outer wall clamping seats 3 are symmetrically located on both sides of the two groups of elastic clamping seats 2, and the two pipe outer wall clamping seats 3 are attached to the surface of the flange 1 and slide. A distance adjusting component for adjusting the position of the pipe outer wall clamping seat 3 is arranged on the side wall of the flange 1, and a locking member is arranged on the distance adjusting component. The pipe outer wall clamping seat 3 near the edge of the flange 1 is moved towards the outer wall of the butt joint pipe through the distance adjusting component.

[0034] After the pipe outer wall clamp seat 3 is attached to the outer wall of the pipe, the position of the pipe outer wall clamp seat 3 is locked by the locking member, thus ensuring the stability of the butt joint between the flange 1 and the pipe, and further ensuring the sealing performance after the pipes are connected.

[0035] When the flange 1 is docked with a special pipe interface, the two sets of elastic clamp seats 2 on both sides of the flange holes are gathered, causing the elastic clamp seats 2 to generate elastic force. Then, the two sets of elastic clamp seats 2 are simultaneously inserted into the inner wall of the pipe docking port and are clamped on the inner wall of the pipe docking port through the elastic deformation of the elastic clamp seats 2. Then, the distance adjustment components on both sides are respectively operated to move the pipe outer wall clamp seats 3 on both sides to the outer wall of the pipe, and then the position of the pipe outer wall clamp seats 3 is locked by the locking member.

[0036] By adjusting the positions of the pipe outer wall clamp seats 3 on both sides, it is applicable to pipes of different specifications, making it more convenient for the flange 1 to be docked with a special pipe, thus ensuring the applicability of the flange 1, avoiding gaps at the docking place, and further ensuring the sealing performance after the flange 1 is docked with the special pipe.

[0037] The distance adjustment component includes a rotating seat 23 rotatably arranged on the side wall of the flange 1, and a pushing frame 24 is penetrated through the rotating seat 23. A bearing is embedded and installed on the surface of the flange 1 and close to the pipe outer wall clamp seat 3, and the rotating seat 23 is embedded and installed inside the bearing, enabling the rotating seat 23 to rotate on the surface of the flange 1. A through hole penetrating the inner cavity is horizontally opened on the outer wall of the rotating seat 23, and the pushing frame 24 passes through the through hole and is fixedly embedded inside the through hole. So that the pushing frame 24 rotates with the rotating seat 23.

[0038] When adjusting the position of the pipe outer wall clamp seat 3, rotate one end of the pushing frame 24 extending outside the rotating seat 23 towards the outer wall direction of the pipe outer wall clamp seat 3, so that the other end of the pushing frame 24 pushes the pipe outer clamp seat 3 to move towards the direction of the elastic clamp seat 2, and moves the pipe outer clamp seat 3 to fit on the outer wall of the butt joint pipe.

[0039] Among them, the locking member includes a chuck 25 sleeved on the outer wall of the rotating seat 23, and a locking bolt 27 is threadedly connected to the chuck 25. The chuck 25 is fixedly sleeved on the outer wall of the rotating seat 23 through the mounting hole opened at the center, so that the chuck 25 rotates with the rotating seat 23, and the chuck 25 is located below the pushing frame 24. The locking bolt 27 is threadedly connected to the top of the chuck 25.

[0040] When the pipe outer wall clamp seat 3 is pushed to move by rotating the pushing frame 24, after the pipe outer wall clamp seat 3 fits onto the outer wall of the pipe, the locking bolt 27 is screwed on the chuck 25, thereby locking the position of the pipe outer wall clamp seat 3 and ensuring the stability of the butt joint between the flange 1 and the pipe interface.

[0041] A support base 7 is fixedly installed on the side wall of the flange 1. An active column 26 is fixedly installed on the outer wall of the pipe outer wall clamp seat 3. One end of the active column 26 away from the pipe outer wall clamp seat 3 penetrates through the side wall of the support base 7 and extends into the inner cavity. One end of the active column 26 passes through the side wall of the support base 7 and extends into the inner cavity, so that the support base 7 and the active column 26 form a telescopic structure. Through the sliding fit between the active column 26 and the support base 7, the stability of the pipe outer wall clamp seat 3 in the moving direction on the flange 1 is ensured.

[0042] An installation ear 4 is slidably arranged on the circumferential outer wall of the flange 1, and a position locking component is arranged on the installation ear 4. According to the position locking component, the installation ear 4 can be fixed at an accurate installation position.

[0043] It should be noted that the position locking component includes a transmission clamping column 8 longitudinally penetrating through the inner cavity of the installation ear 4. A through hole penetrating through the inner cavity is longitudinally opened on the side of the installation hole of the installation ear 4. The transmission clamping column 8 passes through the through hole, and both ends of the transmission clamping column 8 extend to the outside. A wedge-shaped clamping groove 15 is formed on the outer wall of the transmission clamping column 8, and a positioning bolt 11 opposite to the wedge-shaped clamping groove 15 is threadedly connected to the side wall of the installation ear 4. A threaded hole 13 is horizontally opened in the side direction of the installation ear 4, and the threaded hole 13 is communicated with the through hole of the transmission clamping column 8.

[0044] A socket 6 is fixedly installed on the side wall of the installation ear 4. A directional sliding seat 14 is embedded in the inner cavity of the socket 6, and an elastic member 17 is arranged between the directional sliding seat 14 and the bottom of the inner wall of the socket 6. The sliding seat 14 is connected to the transmission clamping column 8. An installation slideway 5 is circumferentially installed on the circumferential outer wall of the flange 1. A guide groove 10 is opened on the side wall of the installation ear 4 facing the flange 1. The cross sections of the slideway 5 and the guide groove 10 are both T-shaped, so that the installation ear 4 slides on the outer wall of the flange 1, and the T-shaped slideway 5 and the guide groove 10 prevent the installation ear 4 from detaching.

[0045] The socket 6 is fixedly installed on the side of the installation ear 4 in a fitting manner. A sliding cavity is opened at the top of the socket 6. The directional sliding seat 14 is movably embedded in the sliding cavity, so that the directional sliding seat 14 slides on the inner wall of the socket 6 in a fitting manner. The tops of the directional sliding seat 14 and the transmission clamping column 8 are simultaneously vertically fixed to the bottom of the connecting plate 12, so that the transmission clamping column 8 and the directional sliding seat 14 move synchronously. The elastic member 17 can be a compression spring, and both ends of the elastic member 17 are respectively fixedly installed on the directional sliding seat 14 and the bottom of the inner wall of the socket 6.

[0046] When adjusting the mounting ear 4 according to the installation position of the flange 1, slide the mounting ear 4 on the circumferential outer wall of the flange 1. After the mounting ear 4 slides to the appropriate position, screw the positioning bolt 11 into the threaded hole 13 so that the hemispherical end of the positioning bolt 11 fits and slides on the inclined surface of the wedge-shaped card slot 15. With the extrusion force of the positioning bolt 11 on the transmission card column 8, the bottom end of the transmission card column 8 is clamped on the surface of the slideway 5, thereby locking the position of the mounting ear 4.

[0047] During the process that the transmission card column 8 is forced to be clamped on the slideway 5, the transmission card column 8 drives the directional slide seat 14 to slide into the inner cavity of the socket 6 through the connecting plate 12, so that the elastic member 17 is compressed and generates elastic force. When the position of the mounting ear 4 needs to be adjusted, take out the positioning bolt 11 from the side of the socket 6. At this time, the directional slide seat 14 moves through the elastic force of the elastic member 17, so that the directional slide seat 14 drives the bottom end of the transmission card column 8 to move away from the surface of the slideway 5 through the connecting plate 12, and then continue to adjust the position of the mounting ear 4.

[0048] The clamping end of the positioning bolt 11 and the wedge-shaped card slot 15 is hemispherical. Through the hemispherical clamping end, the friction between the positioning bolt 11 and the transmission card column 8 is reduced, thereby ensuring the smoothness of the position adjustment process of the mounting ear 4.

[0049] In addition, a directional guide rod 18 is fixedly installed at the bottom of the directional slide seat 14, a directional guide groove 19 opposite to the directional guide rod 18 is opened at the bottom of the inner cavity of the socket 6, and the elastic member 17 is sleeved outside the directional guide rod 18. Through the sliding fit of the directional guide rod 18 and the directional guide groove 19, the position deviation of the directional slide seat 14 is prevented, thereby ensuring the accuracy of the position locking of the mounting ear 4.

[0050] In addition, a sealing gasket 9 is embedded on the side wall of the flange 1. The sealing gasket 9 is made of elastic material, and the sealing performance of the butt joint between the flanges 1 is ensured through the sealing gasket 9.

[0051] Furthermore, the pushing end of the pushing frame 24 is hemispherical. Through the hemispherical pushing end, the friction during the process of pushing the pipe outer wall clamp seat 3 is reduced, thereby ensuring the smoothness of the position adjustment process of the pipe outer wall clamp seat 3.
