Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and more specifically, to a seamless steel elbow with an internal support structure. Background Technology

[0002] Seamless elbows are pipe fittings with a certain angle of curvature, made from seamless steel pipes of high-quality carbon steel, stainless steel, alloy steel, etc., through specific processes. Common bending angles include 45°, 90°, and 180°. They are designed to change the direction of the pipeline so that fluids can be transported according to design requirements.

[0003] The larger the bending angle of a bend, the greater the impact force it experiences during internal liquid transport. The continuous impact of the liquid on the bend's bending surface during high-pressure flow easily leads to damage and shortens its service life. Existing 180-degree elbows, with their simple structure, require frequent maintenance, increasing operating costs. Therefore, we propose a seamless steel elbow with an internal support structure. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a seamless steel elbow with an internal support structure to solve the technical problems of current high-angle elbows being easily damaged, having a short service life, and increasing costs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a seamless steel elbow with an internal support structure, comprising an elbow and an inner tube. An internal support assembly is installed inside the elbow. The internal support assembly consists of an outer bending member, a buffer ring, and an inner bending member, and the outer bending member and the inner bending member are connected by the buffer ring. The inner tube is threaded at the end of the elbow. An outer cylinder is sleeved and fixed on the outside of the inner tube. A sealing gasket is embedded in the inner side of the opening of the outer cylinder, and the sealing gasket fits the connection between the elbow and the inner tube.

[0006] In use, the outer and inner bends of the inner support assembly fit against the inner walls of the bend on both sides, providing outward support and effectively preventing deformation of the bend caused by external impacts. Buffer rings distributed between the outer and inner bends impact the liquid as it changes direction within the bend during high-pressure liquid flow, dispersing the liquid flow and reducing its impact on the bend. This reduces wear and shortens the service life, decreasing replacement frequency and lowering costs. The inner support assembly is slidably inserted into the bend. After calibration, the inner tube is threaded onto both ends of the bend for positioning. The inner tube's connection end presses against the pressure port to position the inner support assembly. Simultaneously, the sealing gasket of the outer cylinder improves the sealing performance at the connection. This structure allows for convenient installation and removal of the inner support assembly, making it a reusable component and further reducing usage costs.

[0007] Preferably, the outer bend and the inner bend are respectively attached to both sides of the inner wall of the bend, and a number of buffer rings are distributed between the outer bend and the inner bend, the buffer rings being equidistantly distributed along the inner bend angle of the bend.

[0008] Preferably, both ends of the outer and inner bends are provided with pressure ports, and the connecting end face of the inner tube is inserted into the pressure port.

[0009] Preferably, the inner side of the bent pipe port is provided with a connecting screw, the rear end of the inner pipe is provided with a connecting end, and the connecting end is threadedly connected to the connecting screw, and the inner side of the front opening of the inner pipe is provided with an internal screw.

[0010] Preferably, the inner and outer walls of the bend are provided with an anti-oxidation coating, and the bend is made of carbon steel.

[0011] Preferably, the diameter of the buffer ring is smaller than the inner diameter of the bend, and the distance between the buffer ring and the inner wall of the bend is one centimeter.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model designs an internal support component. The outer and inner bends of the internal support component are respectively attached to the inner walls of the bend, thus providing outward support from the inside. This effectively prevents the bend from deforming due to external impacts. The buffer rings distributed between the outer and inner bends first impact the liquid when it changes direction inside the bend during the high-pressure liquid flow process. The buffer rings disperse the liquid flow, reducing the impact of the liquid on the bend, reducing wear and shortening the service life, reducing the frequency of replacement and lowering costs.

[0014] 2. This utility model also designs an inner tube, in which the inner support component is slidably inserted and installed inside the bend. After calibration, the inner tube is threaded at both ends of the bend for positioning. The connecting end of the inner tube is squeezed at the pressure port to position the inner support component. At the same time, the sealing gasket of the outer cylinder improves the sealing performance of the connection. The above structure enables convenient installation and removal of the inner support component, making the inner support component a reusable part and further reducing the cost of use.

[0021] like Figures 1 to 3As shown, this utility model relates to a seamless steel elbow with an internal support structure, comprising a bend 1 and an inner tube 3. The elbow 1 is characterized by an internal support assembly 4 installed inside it. The internal support assembly 4 consists of an outer bend 401, a buffer ring 402, and an inner bend 403. The outer bend 401 and the inner bend 403 are connected by the buffer ring 402. The outer bend 401 and the inner bend 403 respectively conform to the two sides of the inner wall of the elbow 1. A plurality of buffer rings 402 are distributed between the outer bend 401 and the inner bend 403, and the buffer rings 402 are equidistantly distributed along the inner bending angle of the elbow 1. Both ends of the outer bend 401 and the inner bend 403 are... A pressure port 404 is provided, and the end face of the connecting end 301 of the inner tube 3 is inserted into the pressure port 404. The outer bend 401 and the inner bend 403 of the inner support assembly 4 are respectively attached to the two sides of the inner wall of the bend 1 to complete the outward support from the inside, which can effectively prevent the bend 1 from deforming due to external impact. The buffer ring 402 distributed between the outer bend 401 and the inner bend 403 will first impact the buffer ring 402 when the liquid changes direction in the bend 1 during the high pressure liquid flow process. The buffer ring 402 will disperse the liquid flow, reduce the impact of the liquid on the bend 1, reduce wear and shorten the service life, reduce the frequency of replacement and reduce costs.

[0022] like Figures 2 to 5 As shown, this utility model relates to a seamless steel elbow with an internal support structure, comprising a bend 1 and an inner tube 3. The inner tube 3 is threadedly installed at the end of the bend 1. An outer cylinder 2 is sleeved and fixed to the outside of the inner tube 3. A sealing gasket 201 is embedded in the inner side of the opening of the outer cylinder 2, and the sealing gasket 201 fits the connection between the bend 1 and the inner tube 3. A connecting thread 101 is provided on the inner side of the end of the bend 1. A connecting end 301 is provided at the rear end of the inner tube 3, and the connecting end 301 is threadedly connected to the connecting thread 101. An internal thread 302 is provided on the inner side of the opening at the front end of the inner tube 3. Both the inner and outer walls of the bend 1 are coated with an anti-oxidation coating. The bend 1 is made of carbon steel. The diameter of the buffer ring 402 is smaller than that of the bend 1. The inner diameter is small, and the distance between the buffer ring 402 and the inner wall of the bend 1 is one centimeter. The small distance design further increases the dispersion angle after the liquid impacts the buffer ring 402, thereby reducing the friction of the high-pressure liquid on the inner wall of the bend 1. The inner support assembly 4 is installed inside the bend 1 by sliding. After calibration, the inner tube 3 is installed at both ends of the bend 1 by thread to limit the position. The connecting end 301 of the inner tube 3 squeezes the pressure port 404 to position the inner support assembly 4. At the same time, the sealing gasket 201 of the outer cylinder 2 improves the sealing performance of the connection. The above structure makes it easy to install and remove the inner support assembly 4, making the inner support assembly 4 a reusable part and further reducing the cost of use.

[0023] Working Principle: This embodiment provides a seamless steel elbow with an internal support structure. In use, the outer bending member 401 and the inner bending member 403 of the internal support assembly 4 are respectively attached to the two sides of the inner wall of the elbow 1 to complete the outward support from the inside, which can effectively prevent the elbow 1 from deforming due to external impact. The buffer ring 402 distributed between the outer bending member 401 and the inner bending member 403 impacts the buffer ring 402 when the liquid changes direction in the elbow 1 during the high pressure liquid flow process. The buffer ring 402 disperses the liquid flow, reduces the impact of the liquid on the elbow 1, reduces wear and shortens the service life, reduces the frequency of replacement and reduces costs.
