Description

Technical Field

[0001] This utility model belongs to the field of construction pipelines, and specifically relates to a turning branch pipe seat. Background Technology

[0002] A branch pipe fitting, also called a branch pipe stand, is a reinforcing pipe fitting used to connect main pipes and branch pipes, replacing other branch pipe connection types such as reducing tees, reinforcing plates, and reinforced pipe sections. Common branch pipe fittings include 90° branch pipe fittings and 45° branch pipe fittings.

[0003] Traditional branch pipe fitting welding involves first positioning the branch pipe on the main pipe, then drilling a hole, and finally aligning the branch pipe fitting with the main pipe before welding. When space is limited, alignment and welding become difficult, easily leading to misalignment between the branch pipe fitting hole and the main pipe opening.

[0004] When a branch pipe connects to the main pipe, the angle is not necessarily perpendicular to the main pipe. With varying branch pipe connection angles, traditional 90° and 45° branch pipe supports cannot be directly welded to the branch pipe. Furthermore, when branching at the bottom of the pipeline, welding the 90° or 45° branch pipe support to the main pipe before welding the branch pipe and shut-off valve requires sufficient space. When welding branch pipe supports at the bottom of densely packed pipelines or pipelines close to the ground, insufficient space may prevent the welding of branch pipes and shut-off valves. Forcing the welding of branch pipes and shut-off valves may result in insufficient space for pipeline media routing and inconvenience for valve operation.

[0005] When the branch pipe is connected to the main pipe at an off-center angle, or when there are multiple pipes arranged close to the ground or on a vertical plane, there is no space to weld branch pipes and shut-off valves after welding the 90° branch pipe seat, making branch pipe arrangement difficult. The 45° branch pipe seat, on the other hand, presents problems such as high welding difficulty, poor alignment, non-adjustable angle, and difficult welding construction. Furthermore, welding branch pipes and shut-off valves also requires a certain angle and space, resulting in limited welding space. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a simple and reliable directional branch pipe seat that is easy to weld and construct, saves space and welding work, and is suitable for branch pipes connected to the main pipe at different angles. It can be used in a variety of working conditions and has a wide range of applications.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a steering branch pipe seat, including a first pipe section and a second pipe section connected as one piece, wherein the included angle between the first pipe section and the second pipe section is 90° to 180°, the first pipe section is used to connect a branch pipe, the second pipe section is used to connect a main pipe, and a tapered part is integrally provided at the end of the second pipe section away from the first pipe section, and an opening is provided on the main pipe, wherein the tapered part is welded to the opening.

[0008] This utility model of a swivel branch pipe seat features a simple and reliable structure, convenient welding construction, and saves space and welding workload. The branch pipe seat consists of a first pipe section and a second pipe section. The tapered portion of the second pipe section is welded to the main pipe. After an opening is made on the main pipe, the tapered portion is inserted into the opening, and then welding is performed at the junction of the main pipe and the tapered portion. This solves the problems of difficult alignment and high welding difficulty in conventional branch pipe seats, meeting the connection requirements of branch pipes with different access angles and exhibiting good adaptability. The first and second pipe sections of the branch pipe seat are at an angle of 90° to 180°, changing the angle and direction of the first pipe section and providing a large welding operation space, solving the problem that conventional branch pipe seats cannot be directly welded to branch pipes or require a large welding operation space. The first pipe section can be directly connected to branch pipes, or directly connected to short pipes, flanges, or valves, etc. This utility model of a swivel branch pipe seat can be used in various working conditions and has a wide range of applications.

[0009] Preferably, the outer diameter of the wide end of the tapered portion is the same as the outer diameter of the second pipe section, and the narrow end of the tapered portion is welded to the opening.

[0010] Preferably, the outer diameter of the narrow end of the tapered portion is 1.5 to 2.5 mm smaller than the diameter of the opening to ensure effective pipe drainage. If the opening is too large, the second pipe section of the branch pipe will be inserted into the main pipe for too long, affecting the pipe drainage effect.

[0011] Preferably, the slope of the tapered portion is 35° to 45° to facilitate welding.

[0012] Preferably, the opening is made at the bottom and / or other parts of the main pipe to meet the needs of different working conditions such as different access angles of branch pipes, insufficient space between pipes, and difficulty in welding alignment.

[0013] Preferably, the first pipe section is connected to the branch pipe by butt welding, socket welding, threaded connection, or flange connection, depending on the specific working conditions. For example, the first pipe section can be directly welded with a branch short pipe or shut-off valve, etc.

[0014] Preferably, the first pipe section and the second pipe section are made entirely of metal forgings, which are reliable in structure, highly applicable, and easy to promote and apply.

[0015] Compared with the prior art, the present invention has the following advantages: the present invention has a simple and reliable structure for steering branch pipe seat, is convenient for welding construction and saves space and welding workload, and is suitable for branch pipes connected to the main pipe at different angles. It solves the problems of difficulty in centering and welding of conventional branch pipe seats, meets the connection requirements of branch pipes with different access angles, has good adaptability, and solves the problems of conventional branch pipe seats and branch pipes not being able to be directly welded or requiring a large welding operation space. It can be used in a variety of working conditions and has a wide range of applications. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] The steering branch pipe seat in Example 1 is applied when the branch pipe is connected to the main pipe from different directions and angles, such as... Figure 1 and Figure 2 As shown, the steering branch includes a first pipe section 1 and a second pipe section 2 that are integrally connected. The first pipe section 1 and the second pipe section 2 are made of metal forgings. The included angle between the first pipe section 1 and the second pipe section 2 is 135°. The first pipe section 1 is used to connect the branch pipe (not shown in the figure), and the second pipe section 2 is used to connect the main pipe 3. A tapered part 4 is integrally provided at the end of the second pipe section 2 away from the first pipe section 1. An opening 5 is provided at the top of the main pipe 3, and the tapered part 4 is welded to the opening 5.

[0022] In Example 1, the outer diameter of the wide end of the tapered part 4 is the same as the outer diameter of the second pipe section 2, and the narrow end of the tapered part 4 is welded to the opening 5.

[0023] In Example 1, the outer diameter of the narrow end of the tapered part 4 is 2.0 mm smaller than the diameter of the opening 5, and the slope of the tapered part 4 is 45°.

[0024] The steering branch pipe seat in Example 2, such as Figure 3As shown, this is applied to the case where the branch pipe is connected to the main pipe 3 from the bottom. The angle between the first pipe section 1 and the second pipe section 2 is 90°, and the opening 5 is opened at the bottom of the main pipe 3.

[0025] The steering branch pipe seat in Example 3, such as Figure 4 As shown, this is applied to the case where the branch pipe is connected to the main pipe 3 from the bottom. The included angle between the first pipe section 1 and the second pipe section 2 is 135°, and the opening 5 is opened at the bottom of the main pipe 3.

[0026] During the welding of the aforementioned branch pipe seat, after setting an opening 5 on the main pipe 3, the tapered part 4 is inserted into the opening 5, and then welding is performed at the junction of the main pipe 3 and the tapered part 4. This solves the problems of difficult alignment and high welding difficulty in conventional branch pipe seat welding, meets the connection requirements of branch pipes with different access angles, and has good adaptability. In addition, because the angle and direction of the first pipe section 1 are changed, the welding operation space is large, solving the problem that conventional branch pipe seats and branch pipes cannot be directly welded or require a large welding operation space. The connection method between the first pipe section 1 and the branch pipe can be butt welding, socket welding, threaded connection, or flange connection, depending on the specific situation. In addition to branch pipes, the first pipe section 1 can also be directly connected to short pipes, flanges, or valves, etc., and is widely used in different working conditions.
