Technical Field
[0001] The utility model relates to the technical field of three-way joints, in particular to a stainless steel equal-diameter three-way joint. Background Technique
[0002] The stainless steel equal-diameter three-way joint is a pipe fitting specifically used for connecting three pipe branches in a pipeline system. Due to its excellent corrosion resistance, high temperature resistance, and mechanical strength, the stainless steel equal-diameter three-way joint performs well in complex and changeable working environments.
[0003] However, the structure of the traditional three-way joint is relatively simple. In actual use, there will be a certain deviation in misalignment between the pipeline and the joint. The traditional solution is to forcefully install the pipeline even if it is misaligned. However, the joint will deform after long-term use, affecting the sealing performance. Content of the Utility Model
[0004] The purpose of the utility model is to solve the disadvantages that in actual use, there will be a certain deviation in misalignment between the pipeline and the joint. The traditional solution is to forcefully install the pipeline even if it is misaligned. However, the joint will deform after long-term use, affecting the sealing performance, and to propose a stainless steel equal-diameter three-way joint.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A stainless steel equal-diameter three-way joint, including a three-way pipe;
[0007] Three connecting pipes, which are used as connectors between the three-way pipe and the pipeline, and the three connecting pipes are respectively located at the three ends of the three-way pipe;
[0008] Three adjusting parts, which are used to adjust the positions of the connecting pipes. The three adjusting parts are respectively located at the three ends of the three-way pipe. The adjusting part includes an outer cylinder, an inner through pipe, and a limiting ring. The inner through pipe is located between the outer cylinder and the limiting ring.
[0009] In a possible design, an inner convex ring is provided at one end of the inner wall of the outer cylinder. The inner convex ring is threadedly sleeved on the outer wall of the end of the three-way pipe. A cavity is provided between the inner convex ring and the limiting ring. The inner through pipe is located inside the cavity. One end of the connecting pipe is fixedly arranged on the inner wall of the inner through pipe.
[0010] In a possible design, a plurality of first threaded holes arranged in a ring shape are provided on the surface of the limiting ring. A plurality of threaded grooves arranged in a ring shape are provided on the side of the outer cylinder close to the limiting ring. The plurality of threaded grooves are respectively matched with the plurality of first threaded holes.
[0011] In a possible design, a flange ring is fixedly sleeved in the middle of the outer wall of the connecting pipe, and a plurality of second threaded holes arranged in a ring shape are formed on the surface of the flange ring.
[0012] In a possible design, threads are provided at one ends of the inner wall and the outer wall of the connecting pipe away from the tee.
[0013] In a possible design, a sealing ring is provided on the inner wall of the inner convex ring close to the inner through pipe, and the inner through pipe is matched with the sealing ring.
[0014] In this application, during specific use, first use bolts to install on one of the pipes through the flange ring or install it well using the threads on the inner and outer walls of the connecting pipe. When there is a misalignment between a horizontal pipe (refer to the horizontal direction in Figure 2 ) and the connecting pipe, first loosen the bolts on the surface of the limit ring, so that the limit ring and the outer cylinder lose the squeezing and fixing state on the inner through pipe, thereby adjusting the inner through pipe. After aligning the connecting pipe with the horizontal pipe, tighten the bolts on the surface of the limit ring to fix the inner through pipe again, thereby solving the problem of axial error misalignment between the pipes. When it is necessary to adjust the position of the connecting pipe to connect it with the pipe, the outer cylinder can be rotated to extend the connecting pipe into the interior of the pipe, and then it can be connected through the matching threads or second threaded holes on the surface.
[0015] In this utility model, for the stainless steel equal-diameter tee joint, through the connecting pipe, various connection methods can be achieved between the tee and the pipe. Through the threaded settings on the inner and outer walls of the connecting pipe, pipes with different diameters can be adapted. Through the flange ring on the outer wall of the connecting pipe, flange connection can be carried out after inserting one section of the connecting pipe into the interior of the pipe;
[0016] In this utility model, for the stainless steel equal-diameter tee joint, through the adjusting member, the position of the connecting pipe can be adjusted. When there is an axial misalignment between the connecting pipe and the pipe, the connecting pipe can be adjusted within a certain range, thereby having a certain error;
[0017] In this utility model, during use, when there is a misalignment between the pipe and the connecting pipe, the position of the connecting pipe can be adjusted through the adjusting member to solve the misalignment problem and increase its adaptability;
[0018] Through the threads and flange ring on the inner and outer walls of the connecting pipe, the tee joint has more connection methods, thereby further increasing its adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0024] Embodiment 1
[0025] Referring to Figure 1 , an equal-diameter three-way joint includes: a three-way pipe 1 and three connecting pipes 4. These three connecting pipes 4 are respectively located at the three ports of the three-way pipe 1 and are used to connect with pipelines. In order to adjust the positions of the connecting pipes 4, three adjusting members 12 are designed, and they are respectively located at the three ports of the three-way pipe 1.
[0026] Referring to Figure 3 , each adjusting member 12 includes an outer cylinder 2, an inner through pipe 3 and a limiting ring 9. The inner through pipe 3 is located between the outer cylinder 2 and the limiting ring 9 and is used for pipeline connection and adjustment. An inner convex ring 5 is provided at one end of the inner wall of the outer cylinder 2, and the inner convex ring 5 is sleeved on the outer wall of the end of the three-way pipe 1 through a thread, thereby realizing the connection between the adjusting member 12 and the three-way pipe 1.
[0027] Between the inner convex ring 5 and the limiting ring 9, there is a cavity 6, and the inner through pipe 3 is located inside this cavity 6. One end of the connecting pipe 4 is fixedly arranged on the inner wall of the inner through pipe 3, so that the connecting pipe 4 can move in the cavity 6 through the inner through pipe 3, thereby adjusting its position relative to the three-way pipe 1.
[0028] In order to further fix the position of the inner through pipe 3, a plurality of first threaded holes 8 arranged in a ring are opened on the surface of the limiting ring 9, and a plurality of thread grooves 7 arranged in a ring are opened on the side of the outer cylinder 2 close to the limiting ring 9. These thread grooves 7 cooperate with the first threaded holes 8, and the limiting ring 9 is fixed on the outer cylinder 2 through bolts or other fasteners, thereby clamping and fixing the through pipe 3.
[0029] Specifically, when there is a horizontal pipeline for reference Figure 2When there is a misalignment in the horizontal direction in [it] and the connecting pipe 4, first loosen the bolts on the surface of the limit ring 9, so that the limit ring 9 and the outer cylinder 2 lose the extrusion and fixing state of the inner through pipe 3, thereby adjusting the inner through pipe 3. After aligning the connecting pipe 4 with the horizontal pipe, tighten the bolts on the surface of the limit ring 9 to fix the inner through pipe 3 again.
[0030] This application can be used for stainless steel equal-diameter three-way joints and can also be used in other fields applicable to this application.
[0031] Embodiment 2
[0032] Reference Figure 3 , on the basis of Embodiment 1 for improvement: A stainless steel equal-diameter three-way joint, which is applied in the field of three-way joints. For the connection stability between the connecting pipe 4 and the pipe, a flange ring 11 is fixedly sleeved in the middle of the outer wall of the connecting pipe 4, and a plurality of second threaded holes 10 arranged in a ring shape are opened on the surface of the flange ring 11. These second threaded holes 10 can cooperate with the corresponding threaded holes on the pipe, and the connecting pipe 4 and the pipe are firmly connected through bolts or other fasteners.
[0033] In addition, to meet the connection requirements of different pipes, threads are provided at both the inner wall and the outer wall of the connecting pipe 4 at the end far from the three-way pipe 1. In this way, whether it is an inner-threaded or outer-threaded pipe, it can be conveniently connected to the three-way pipe 1 through the connecting pipe 4.
[0034] To further improve the connection tightness, a sealing ring is provided on the inner wall of the inner convex ring 5 on the side close to the inner through pipe 3. When the limit ring 9 squeezes and fixes the inner through pipe 3, it will also squeeze the sealing ring to ensure that it fits tightly, thereby preventing liquid or gas from leaking from the connection.
