Description

Technical Field

[0001] This utility model relates to the field of oil drilling operation technology, and more specifically to a straight pipe with a 360° rotating flange. Background Technology

[0002] At oil drilling sites, pipelines are mostly connected to each other and to skid-mounted manifolds via flanges. However, during the connection process, uneven ground can cause misalignment of bolt holes during flange connections and misalignment of threaded holes during pipeline installation, making on-site connections difficult and labor-intensive.

[0003] Furthermore, existing technologies lack a pipeline connection device that can effectively solve the above problems, especially in the case of rigid pipeline connections, where the flange cannot be freely rotated, thus making it impossible to quickly adjust the relative position of the flange to adapt to the installation difficulties caused by uneven ground.

[0004] Therefore, developing a straight pipe with a 360° rotating flange that can rotate freely and achieve quick connection is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a straight pipe with a 360° rotating flange that can rotate freely and achieve quick connection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A straight pipe with a 360° rotating flange, comprising:

[0008] The channel itself,

[0009] A rotating flange is disposed outside the channel body. A ball groove is provided on the outer circumferential surface of the channel body connected to one end of the rotating flange. A ball hole is opened on the outer surface of the rotating flange, and the ball hole is connected to the ball groove. A steel ball is placed through the ball hole and placed in the ball groove. A rubber stopper is provided in the ball hole to limit the position of the steel ball.

[0010] A fixed flange is located at the end of the channel body away from the rotating flange.

[0011] The beneficial effect of adopting the above technical solution is that, through the cooperation of the channel body, rotating flange, ball groove, ball hole, steel ball and rubber plug, the rotating flange can rotate 360° in the circumferential direction of the channel body. Thus, when connecting with other fixed rigid pipelines or fixed flanges, the relative position of the flange can be quickly adjusted to achieve rapid connection, solving the problem of difficult flange connection caused by uneven ground in the prior art.

[0012] Preferably, the end of the rubber stopper that contacts the steel ball is hemispherical. This hemispherical shape allows for a better fit with the shape of the steel ball, effectively limiting the position of the steel ball within the ball hole and preventing displacement or detachment during rotation, thus ensuring stable rotation of the rotating flange.

[0013] Preferably, a first inner retaining spring is provided at one end of the ball hole near the outside of the rotating flange, the first inner retaining spring securing the rubber plug within the ball hole. The first inner retaining spring firmly secures the rubber plug within the ball hole, preventing the rubber plug from coming out of the ball hole due to external force, further enhancing the fixing effect of the steel ball and ensuring the stability and reliability of the steel ball within the ball groove.

[0014] Preferably, the fixing flange is threadedly connected to the end of the channel body; a set screw is installed on the outside of the fixing flange, and the set screw passes through the fixing flange and connects to the channel body. The threaded connection of the fixing flange to the end of the channel body is simple and quick, facilitating installation and disassembly, and improving the efficiency of on-site installation and maintenance.

[0015] Preferably, an external retaining spring is provided on the side of the fixed flange near the middle of the channel body, and the external retaining spring is engaged with the outside of the channel body.

[0016] Preferably, a second inner retaining spring is provided at the connection between the fixed flange and the set screw, the second inner retaining spring confining the set screw within the fixed flange. The second inner retaining spring securely holds the set screw within the fixed flange, preventing the set screw from loosening or falling off due to external forces during use, thus ensuring the set screw's fixing effect on the fixed flange.

[0017] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a straight pipe with a 360° rotating flange, the beneficial effects of which are:

[0018] (1) The rotating flange in this utility model can rotate freely and can quickly adjust the relative position of the flange, effectively solving the problem of difficult flange connection caused by uneven ground, making the connection between pipelines and between pipelines and skid-mounted manifolds more convenient, greatly shortening the on-site installation time and improving work efficiency.

[0019] (2) It has a simple structure, is easy to process, is flexible in field use, and has strong versatility. It is suitable for various pipeline connection scenarios, which can reduce the complexity and workload of field installation and adapt to different installation environments and requirements.

[0028] Channel body 1,

[0029] Rotary flange 2 is located outside the channel body 1. A ball groove is provided on the outer circumference of one end of the channel body 1 that connects to the rotary flange 2. A ball hole is opened on the outer surface of the rotary flange 2, and the ball hole is connected to the ball groove. A steel ball 3 is placed along the ball hole, and a rubber plug 6 is provided in the ball hole to limit the position of the steel ball 3. The steel ball 3 is placed in the ball groove.

[0030] A fixed flange 4 is located at the end of the channel body 1 away from the rotating flange 2. Steel balls 3 are filled in the ball groove of the channel body 1 to prevent detachment; at the same time, the steel balls 3 act as bearings, allowing the rotating flange 2 to rotate 360° in the circumferential direction of the channel body 1.

[0031] To further optimize the above technical solution, the end of the rubber stopper 6 that contacts the steel ball 3 is hemispherical. The rubber stopper 6 can prevent the steel ball 3 from falling out of the ball groove.

The first inner retaining spring 7 confines the rubber plug 6 inside the ball hole. The first inner retaining spring 7 is engaged on the outer circumferential surface of the rotary flange 2 and is located on the outer wall of the ball hole, pressing the rubber plug 6 inside the ball hole and preventing the rubber plug 6 from coming out of the ball hole.

[0033] To further optimize the above technical solution, the fixed flange 4 is threaded to the end of the channel body 1; a set screw 5 is installed on the outside of the fixed flange 4, and the set screw 5 passes through the fixed flange 4 and connects to the channel body 1. The fixed flange 4 and the channel body 1 are connected by internal and external threads, and the threads are trapezoidal threads.

[0034] To further optimize the above technical solution, an external retaining spring 8 is provided on the side of the fixed flange 4 near the middle of the channel body 1. The external retaining spring 8 is engaged with the outside of the channel body 1. The external retaining spring 8 is engaged with the outer circumferential surface of the channel body 1, and plays a stopping role for the fixed flange 4.

[0035] To further optimize the above technical solution, a second inner retaining spring 9 is provided at the connection between the fixed flange 4 and the set screw 5. The second inner retaining spring 9 confines the set screw 5 within the fixed flange 4. The set screw 5 prevents the fixed flange 4 from loosening. The second inner retaining spring 9 is engaged on the outer circumferential surface of the fixed flange 4, and the locking screw 5 is located within the inner ring of the second inner retaining spring 9, which can limit the position of the set screw 5, making the position of the set screw 5 more stable for the fixed flange 4.
