Description

Technical Field

[0001] This utility model relates to the field of oil pipeline technology, specifically a stamped and formed leak-proof oil pipeline component. Background Technology

[0002] During the production of oil pipelines, some oil pipelines need to be stamped and bent, and the connections between oil pipelines need to be sealed. Traditionally, oil pipelines are sealed by fixing with bolts. The bolts are exposed and lack protection, and have been corroded over time, making subsequent disassembly inconvenient.

[0003] For example, the authorized patent document with application number CN202122885887.5 discloses a leak-proof component for heating pipes, which includes a heating pipe body. There are two heating pipe bodies, and a first sealing ring is provided on the side of each of the two sets of second sealing rings that are close to each other. The two sets of fastening plates are connected by bolts. The two sets of fastening plates can be moved to the side that is close to each other by bolts and nuts. In the above structure, there is a lack of protection for the bolts, that is, the bolts are exposed to the outside without protection, and corrosion has occurred over a long period of time, which makes subsequent disassembly inconvenient. Therefore, we need to provide a stamped and formed leak-proof oil pipeline component. Utility Model Content

[0004] The purpose of this utility model is to provide a stamped and formed oil leakage prevention pipeline assembly, which has a protective mechanism on the outside of the bolts, which can quickly protect the seals and bolts, protect the surface of the bolts, reduce dust intrusion, and solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamped oil leakage-proof pipeline assembly, comprising:

[0006] The system includes pipes, seals, rectangular plates, bolts, and protective mechanisms. Seals are provided on adjacent sides of the two pipes to enhance the sealing between them. Rectangular plates are fixedly installed on the surfaces of both pipes, and protective mechanisms are installed on the surfaces of the rectangular plates to protect the bolts from external impacts.

[0007] The protective mechanism includes a cover, buckles, and connectors. The covers are slidably mounted on the surfaces of the two rectangular plates. Buckles are fixedly mounted on both sides of one cover, and connectors are mounted on both sides of the other cover. The connectors engage with the buckles to achieve a close and fixed fit between the two covers.

[0008] Preferably, the connector includes a frame, springs, a slide, a rotating seat, and a slot. The frame is fixedly installed on a cover without buckles, and a slide is slidably installed inside. Two springs are engaged with the slide inside the frame. A rotating seat is hinged to one side of the slide, and a slot is provided inside the rotating seat to engage with the buckles.

[0009] Preferably, the buckle has a protrusion on one side to limit the rotation seat, and a toggle plate is fixedly installed on one side of the rotation seat.

[0010] Preferably, the bolt component includes a limiting bolt and a limiting nut. Four limiting bolts are fixedly installed on one side of the rectangular plate, and one end of the limiting bolt penetrates the surface of another rectangular plate and is threaded with a limiting nut.

[0011] Preferably, the thread helix angle between the limiting bolt and the limiting nut is less than the equivalent friction angle.

[0012] Preferably, the sealing element includes an installation ring, an annular groove, and a sealing ring. An installation ring is fixedly installed on each of the two pipes on opposite sides. The surface of the installation ring has two annular grooves, and a sealing ring is installed in the annular groove. The diameter of the sealing ring is greater than twice the depth of the annular groove.

[0013] Preferably, a deformable annular sealing seat is fixedly installed on each of the two pipes on opposite sides.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a stamped and formed oil leakage-proof pipeline assembly, comprising:

[0024] Pipe 1, seal 2, rectangular plate 3, bolt 4 and protective mechanism 5. Seals 2 are provided on the adjacent side of the two pipes 1 to enhance the sealing between the pipes 1. Rectangular plates 3 are fixedly installed on the surface of the two pipes 1. The surface of the rectangular plates 3 is equipped with a protective mechanism 5 to protect the bolt 4 and prevent the bolt 4 from being hit by external impact.

[0025] The protective mechanism 5 includes a protective cover 51, a buckle 52, and a connector 53. The protective covers 51 are slidably installed on the surfaces of the two rectangular plates 3. The buckles 52 are fixedly installed on both sides of one of the protective covers 51, and the connectors 53 are installed on both sides of the other protective cover 51. The connectors 53 are engaged with the buckles 52 to achieve a close and fixed fit between the two protective covers 51.

[0026] Specifically, the two stamped curved pipes 1 are sealed by a seal 2 and fixed by bolts 4, which has an oil leakage prevention function. A protective mechanism 5 is provided on the outside of the bolts 4, which can quickly protect the seal 2 and the bolts, protect the surface of the bolts 4, and reduce dust intrusion. The cover 51 forms a closed space with the connector 53 through the buckle 52, which reduces the adhesion of debris to the bolts 4 and blocks light, protecting the rubber parts and achieving an anti-aging effect.

[0027] The connector 53 includes a frame 531, a spring 532, a slide 533, a rotating seat 534, and a slot 535. The frame 531 is fixedly installed on the cover 51 without the buckle 52, and the slide 533 is slidably installed inside. Two springs 532 are engaged with the slide 533 and the frame 531. The rotating seat 534 is hinged to one side of the slide 533. The rotating seat 534 has a slot 535 that engages with the buckle 52.

[0028] Furthermore, the frame 531 is fixed on the cover 51, and the slide seat 533 is slidably installed inside. The slide seat 533 and the frame 531 are elastically connected by two springs. A rotating seat 534 is hinged to one side of the slide seat 533. A slot 535 that cooperates with the buckle 52 is opened in the rotating seat 534. Pulling the actuating plate 6 drives the rotating seat 534 to rotate and stretches the spring, so that the slot 535 is aligned with the buckle 52 and then released. The spring returns to its original position and pushes the rotating seat 534 to lock the buckle 52, forming an elastic lock, so as to realize the quick loading and unloading of the cover 51.

[0029] The buckle 52 has a protrusion on one side to limit the rotation seat 534, and a toggle plate 6 is fixedly installed on one side of the rotation seat 534.

[0030] It is worth noting that a protrusion is provided on one side of the buckle 52, and a limiting groove is opened at the corresponding position of the rotating seat 534. The actuating plate 6 is vertically fixed on the outside of the rotating seat 534. When the buckle 535 is engaged with the buckle 52, the protrusion is embedded in the limiting groove to form a mechanical limit, which restricts the circumferential displacement of the rotating seat 534.

[0031] Bolt component 4 includes limiting bolts 41 and limiting nuts 42. Four limiting bolts 41 are fixedly installed on one side of rectangular plate 3, and one end of the limiting bolt 41 passes through the surface of another rectangular plate 3 and is threaded with a limiting nut 42.

[0032] It should be noted that the bolt component 4 includes a limiting bolt 41 and a limiting nut 42. The rectangular plate 3 is fixed by welding four limiting bolts 41. The limiting bolts 41 pass through the through holes of the two rectangular plates 3. When the limiting nut 42 is tightened, the preload generated between the flange surface and the contact surface of the rectangular plate 3 is applied.

[0033] The thread helix angle between the limit bolt 41 and the limit nut 42 is less than the equivalent friction angle;

[0034] The threaded surface is coated with PTFE, and the thread helix angle between the limit bolt 41 and the limit nut 42 is less than the equivalent friction angle, which has a self-locking function. The surface is coated to reduce dust adhesion, and the thread can be used normally even if it contains dust.

[0035] The sealing element 2 includes a mounting ring 21, an annular groove 22 and a sealing ring 23. The mounting ring 21 is fixedly installed on one side of each of the two pipes 1. The mounting ring 21 has two annular grooves 22 on its surface, and the sealing ring 23 is installed in the annular grooves 22. The diameter of the sealing ring 23 is greater than twice the depth of the annular groove 22.

[0036] Specifically, the mounting ring 21 is made of aluminum alloy with double annular grooves 22 on its surface. Hydrogenated nitrile rubber sealing rings 23 are installed in the grooves. When the pipe 1 is connected, the sealing rings 23 are compressed to form a double seal in the radial and axial directions, reducing contact stress.

[0037] Deformable annular sealing seats 7 are fixedly installed on opposite sides of both pipes 1;

[0038] Among them, the end face of the pipe 1 is fixed with an annular sealing seat 7, which is made of EPDM rubber. When the pipe 1 is connected, the sealing seat is compressed to form a surface contact seal.

[0039] The threaded connections involved in this application all have a self-locking function and are coated with a coating to reduce dust adhesion. They can be used normally even if there is dust inside the thread. The thread surface is coated with a PTFE coating, which has low surface energy and self-lubricating properties. Even if dust enters the thread, the self-lubricating properties can ensure the thread rotation and maintain normal adjustment function. The anti-corrosion properties of the coating extend the service life of the thread.

[0040] This device has mounting rings 21 fixedly installed at adjacent ends of the two pipes 1, and two annular grooves 22 are formed inside the mounting rings 21. Sealing rings 23 are located within the annular grooves 22, providing a seal. Simultaneously, annular sealing seats 7 are provided at one end of the pipes 1, and the two annular sealing seats 7 fit together to provide another seal. The annular sealing seats 7 and the two sealing rings 23 are all made of deformable rubber. When the two pipes 1 are joined, four limiting bolts 41 on one of the protective covers 51 penetrate through them. Another protective cover 51 is installed on the surface and threaded with four limit nuts 42 to fix the two pipes 1. After installation, protective covers 51 slide on both rectangular plates 3. One protective cover 51 has buckles 52 fixedly installed on both sides, and the other protective cover 51 has connectors 53 on both sides. By pulling the rotating seat 534, the sliding seat 533 moves in the frame 531, and the spring 532 is stretched, which engages the slot 535 in the rotating seat 534 with the buckle 52 to fix the two protective covers 51.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
