Description

Technical Field

[0001] This utility model relates to the field of elbows, specifically a forged steel socket weld elbow that is easy to connect and seal. Background Technology

[0002] In the field of pipeline connections, forged steel socket weld elbows are a commonly used connecting component to connect two pipelines. While traditional forged steel socket weld elbows can securely connect pipelines to the elbow body through welding, they have some shortcomings in terms of connection sealing and protection of the weld joint.

[0003] On the one hand, traditional socket weld elbows rely primarily on welding to achieve a seal when connected to pipelines. However, welding quality is affected by various factors, such as welding process and operator skill level. Any welding defects can easily lead to leaks, affecting the normal operation of the pipeline system. Furthermore, relying solely on welding for sealing means that, over long-term use, the welded area is susceptible to environmental factors (such as humidity, temperature changes, and chemical corrosion), accelerating corrosion and further increasing the risk of leaks.

[0004] On the other hand, traditional socket weld elbows lack effective protective measures for the welded joint between the pipe and the elbow. The welded joint is exposed to the elements, making it susceptible to intrusion from external moisture, dust, and other impurities. These impurities accelerate corrosion and shorten the service life of the pipeline system. Furthermore, during pipeline operation, the welded joint may be subjected to external forces; without protection, it is more prone to damage, leading to leaks.

[0005] Therefore, developing a forged steel socket weld elbow that can improve connection sealing and effectively protect the weld joint is of great practical significance. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a forged steel socket weld elbow that facilitates connection and sealing, comprising a forged steel socket weld elbow body 1, with socket sleeves 2 fixed at both ends of the forged steel socket weld elbow body 1, and a sealing gasket 3 fixed inside the socket sleeve 2, the sealing gasket 3 being an L-shaped ring; after inserting the pipe into the socket sleeve 2, the end of the pipe tightly abuts against the sealing gasket 3, welding the pipe and the socket sleeve 2 together, with pipes installed at both ends of the forged steel socket weld elbow body 1, thus enabling the connection of two pipes.

[0022] The outer wall of the socket sleeve 2 has a reserved groove 4, and a collar 5 is fitted inside the reserved groove 4. An elastic cover 6 is fixed to one side of the collar 5. The elastic cover 6 is expanded and fitted into the reserved groove 4. The reserved groove 4 is an annular groove, and the outer diameter of the collar 5 is equal to the outer diameter of the socket sleeve 2. A limiting element is provided between the collar 5 and the reserved groove 4. The limiting element includes a rubber ring 9 and a retaining groove 8. The retaining groove 8 is an annular groove, and the rubber ring 9 is a circular ring structure with an arc-shaped cross-section. There are two rubber rings 9, and both rubber rings 9 are fitted and fixed in the reserved groove 4. The rubber ring 9 and the retaining groove 8 match. After the rubber ring 9 extends into the retaining groove 8, the collar 5 is locked in the reserved groove 4. When the pipe is not installed in the socket sleeve 2, the elastic cover 6 is expanded and retracted into the reserved groove 4. When the pipe is installed and fixed in the socket sleeve 2, the collar 5 is moved to slide along the reserved groove 4 until one end of the elastic cover 6 extends out of the reserved groove 4.

[0023] The elastic cover 6 is shaped like a frustum. After one end of the elastic cover 6 is pushed out of the reserved groove 4, the expanded part of the elastic cover 6 springs back to its original position, and a rubber ring 7 is fixed to one end of the elastic cover 6. A rubber cover 10 is fitted and fixed to the outer wall of the elastic cover 6. After the elastic cover 6 is pushed out of the reserved groove 4, one end of the elastic cover 6 and the rubber ring 7 both spring back and fit onto the pipe. The elastic cover 6 covers the weld between the pipe and the socket sleeve 2, reducing corrosion at the weld and thus preventing leakage at the weld. After the rubber cover 10 covers the elastic cover 6, even if the elastic cover 6 breaks, external moisture will not enter the elastic cover 6 due to the coverage of the rubber cover 10.

[0024] Instructions for using the forged steel socket weld elbow for easy connection and sealing: Before pipe installation, the elastic cover 6 is expanded and retracted into the pre-reserved groove 4 on the outer wall of the socket sleeve 2. At this time, the collar 5 is located within the pre-reserved groove 4, and the elastic cover 6 is in a compressed state. Insert the pipe into the socket sleeves 2 at both ends of the forged steel socket weld elbow body 1, ensuring the pipe ends are firmly pressed against the sealing gasket 3 fixed inside the socket sleeve 2. The sealing gasket 3 is an L-shaped ring, providing initial sealing. Weld the pipe and socket sleeve 2 together, allowing the forged steel socket weld elbow body 1 to connect the two pipes. After the pipe is installed and fixed in the socket sleeve 2, move the collar 5 to allow it to slide along the pre-reserved groove 4. The reserved groove 4 is an annular groove, and the outer diameter of the collar 5 is equal to the outer diameter of the socket sleeve 2. A limiting element is provided between the collar 5 and the reserved groove 4. The limiting element includes a rubber ring 9 and a retaining groove 8. The retaining groove 8 is an annular groove, and the rubber ring 9 is a circular ring structure with an arc-shaped cross-section, and there are two of them. Both rubber rings 9 are fitted and fixed in the reserved groove 4. The rubber ring 9 and the retaining groove 8 match. When the rubber ring 9 extends into the retaining groove 8, the collar 5 is braked in the reserved groove 4 to prevent the collar 5 from moving at will. As the collar 5 slides, one end of the elastic cover 6 extends out of the reserved groove 4. The elastic cover 6 is a frustum-shaped cover. When one end of the elastic cover 6 is pushed out of the reserved groove 4, the expanded part of the elastic cover 6 springs back to its original position. A rubber ring 7 is fixed to one end of the elastic cover 6. After the elastic cover 6 is pushed out of the reserved groove 4, one end of the elastic cover 6 and the rubber ring 7 rebound and fit onto the pipe, covering the weld between the pipe and the socket sleeve 2, reducing the possibility of corrosion at the weld, and thus preventing leakage at the weld. A rubber cover 10 is fixed to the outer wall of the elastic cover 6. After the rubber cover 10 covers the elastic cover 6, even if the elastic cover 6 breaks, external moisture will not enter the elastic cover 6 due to the coverage of the rubber cover 10, further enhancing the sealing and protection effect.

[0025] 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.
