Description

Technical Field

[0001] This utility model relates to the field of reducing diameter assemblies, and in particular to a reducing diameter assembly resistant to high temperature overlay welding. Background Technology

[0002] A reducing assembly is a pipe fitting used to connect pipes or equipment of different diameters. It is commonly used in piping systems to achieve a transition between different pipe diameters. Its function is to connect two pipes of different diameters together to ensure that fluid can pass through smoothly. It is a reducing assembly with high temperature resistance and weld overlay and is quite common in existing technology.

[0003] Existing technologies, such as the utility model patent with publication number CN206468956U, disclose a Y-type forged reducing tee assembly. This patent uses a vertically arranged main pipe channel interface section. The upper end of the main pipe channel interface section is connected to a first branch pipe channel connection section via a first elbow connection section to the upper left. Symmetrically arranged first and second buffer holes are respectively provided in the first and second reinforcing zones, and first and second high-temperature resistant buffer strips are embedded in the first and second buffer holes, respectively. This utility model Y-type forged reducing tee assembly has the advantages of balanced airflow distribution, reduced pipe resistance, elimination of stress concentration at the tee junction, improved service life, and simplified pipe system installation.

[0004] The inventors discovered in their daily work that, in the existing technology, when installing the butt joint pipe onto the reducing assembly body, the traditional method is to use a flange connection. When personnel need to maintain the connection between the butt joint pipe and the reducing assembly body, the flange connection is very complicated and requires the use of external tools to complete the maintenance, which leads to low work efficiency. Summary of the Invention

[0005] The purpose of this utility model is to solve the problem that in the existing technology, when personnel need to maintain the connection between the connecting pipe and the reducing assembly body, the flange connection is very complicated and requires the use of external tools to complete the maintenance, which leads to low work efficiency. Therefore, a high-temperature resistant weldable reducing assembly is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides a high-temperature resistant weldable reducing assembly, comprising: a reducing assembly body and a butt joint structure. Both ends of the reducing assembly body are fitted with butt joint pipes via the butt joint structure. The arc surface of the reducing assembly body has a butt joint structure, which includes two fixing rings, two positioning rings, and two limiting rings. The two positioning rings are fixedly connected to the reducing assembly body, the two fixing rings are respectively fixedly connected to the butt joint pipes, and the two limiting rings are respectively fixedly connected to the butt joint pipes. The inner wall of the positioning ring has three positioning holes, and the arc surface of the positioning ring is fixedly connected to three fixing brackets. The inner wall of each fixing bracket is fixedly connected to a positioning rod, and the arc surface of each positioning rod is rotatably connected to a rotating plate. The rotating plate is close to the reducing assembly body. A connecting block is fixedly connected to one side of the eccentric assembly body. A positioning groove is formed on the inner wall of the connecting block. Three limiting rods are fixedly connected to the side of the fixing ring near the eccentric assembly body. The limiting rods are slidably connected to the positioning holes. A rotating ring is rotatably connected to the side of the fixing ring away from the limiting rods. The rotating ring is rotatably connected to the connecting pipe. Three auxiliary grooves are formed on the inner wall of the rotating ring. Fixed blocks are slidably connected to the inner wall of the auxiliary grooves. The three fixed blocks are fixedly connected to the fixing ring. Three retaining strips are fixedly connected to the side of the rotating ring away from the fixing ring. The retaining strips are slidably connected to the positioning grooves. A coil spring is provided on the side of the limiting ring and the rotating ring that are close to each other. The two ends of the coil spring are fixedly connected to the limiting ring and the rotating ring respectively. Three positioning blocks are fixedly connected to the arc surface of the fixing ring.

[0007] The effect achieved by the above components is as follows: when personnel need to install the connecting pipe onto the reducing assembly body, they can first move the connecting pipe to allow the limiting rod to slide into the inner wall of the positioning hole, making the connecting pipe abut against the reducing assembly body. Then, personnel can rotate the rotating plate and the rotating ring until the retaining strip slides into the inner wall of the positioning groove, thereby facilitating personnel to quickly install the connecting pipe onto the reducing assembly body and improving the installation efficiency.

[0008] Preferably, a protective pad is fixedly connected to the side of the positioning block near the rotating plate, and the protective pad abuts against the rotating plate.

[0009] The effect achieved by the above components is that the protective pad can protect the rotating plate and prevent the rotating plate from directly contacting the positioning block.

[0010] Preferably, the circular arc surface of the rotating ring is fixedly connected to three movable blocks, and the cross-section of the movable blocks is rectangular.

[0011] The effect achieved by the above components is that the movable block allows personnel to easily rotate the rotating ring, which can improve the ease of operation for personnel.

[0012] Preferably, the inner wall of the movable block is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly provided on the movable block.

[0013] The effect achieved by the above components is that the anti-slip groove can increase the friction between the personnel's hands and the moving block, and can prevent the personnel from being misaligned during the movement of the moving block.

[0014] Preferably, a guide block is fixedly connected to the end of the limiting rod away from the fixing ring.

[0015] The effect achieved by the above components is that the guide block can limit the position of the limiting rod, making it convenient for personnel to slide the limiting rod into the inner wall of the positioning hole.

[0016] Preferably, the rotating plate is made of stainless steel.

[0017] The effect achieved by the above components is that the stainless steel plate has high strength and good wear resistance, which can prevent the plate from deforming during short-term use.

[0018] Compared with related technologies, the high-temperature resistant weld overlay assembly provided by this utility model has the following beneficial effects: By setting up a docking structure, when personnel need to install the connecting pipe onto the reducing assembly body, the docking structure can facilitate quick and easy installation, thereby accelerating the installation speed and improving installation efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figure 1 The present invention provides a high-temperature resistant weldable reducing assembly, comprising: a reducing assembly body 1 and a butt joint structure 3. Both ends of the reducing assembly body 1 are equipped with butt joints 2 via the butt joint structure 3, and the arc surface of the reducing assembly body 1 is provided with the butt joint structure 3.

[0024] In the embodiments of this utility model, please refer to Figures 2 to 4The docking structure 3 includes two fixing rings 301, two positioning rings 302, and two limiting rings 309. The two positioning rings 302 are fixedly connected to the body 1 of the reducing assembly. The two fixing rings 301 are fixedly connected to the connecting pipe 2, and the two limiting rings 309 are fixedly connected to the connecting pipe 2. The inner wall of the positioning ring 302 has three positioning holes 303. The arc surface of the positioning ring 302 is fixedly connected to three fixing brackets 304. The inner wall of the fixing brackets 304 is fixedly connected to positioning rods 305. The arc surface of the positioning rods 305 is rotatably connected to a rotating plate 306. The side of the rotating plate 306 near the body 1 of the reducing assembly is fixedly connected to a connecting block 307. The inner wall of the connecting block 307 has a positioning groove 308. The side of the fixing rings 301 near the body 1 of the reducing assembly is fixedly connected to... There are three limiting rods 311, which are slidably connected to the positioning holes 303. A rotating ring 313 is rotatably connected to the side of the fixed ring 301 away from the limiting rods 311. The rotating ring 313 is rotatably connected to the connecting pipe 2. Three auxiliary grooves 315 are provided on the inner wall of the rotating ring 313. Fixed blocks 314 are slidably connected to the inner wall of the auxiliary grooves 315. The three fixed blocks 314 are fixedly connected to the fixed ring 301. Three locking strips 320 are fixedly connected to the side of the rotating ring 313 away from the fixed ring 301. The locking strips 320 are slidably connected to the positioning grooves 308. A coil spring 310 is provided on the side of the limiting ring 309 and the rotating ring 313 that are close to each other. The two ends of the coil spring 310 are fixedly connected to the limiting ring 309 and the rotating ring 313 respectively. Three positioning blocks 318 are fixedly connected to the arc surface of the fixed ring 301. When personnel need to install the connecting pipe 2 onto the reducing assembly body 1, they can first move the connecting pipe 2 to allow the limiting rod 311 to slide into the inner wall of the positioning hole 303, making the connecting pipe 2 abut against the reducing assembly body 1. Then, personnel can rotate the rotating plate 306 and the rotating ring 313 until the retaining strip 320 slides into the inner wall of the positioning groove 308. This allows personnel to quickly and easily install the connecting pipe 2 onto the reducing assembly body 1, improving installation efficiency. A protective pad 319 is fixedly connected to the side of the positioning block 318 near the rotating plate 306, and the protective pad 319 abuts against the rotating plate 306. The protective pad 319 protects the rotating plate 306 and prevents direct contact between the rotating plate 306 and the positioning block 318. Three moving blocks 316 with rectangular cross-sections are fixedly connected to the arc surface of the rotating ring 313. The movable block 316 allows for easy rotation of the rotating ring 313, improving operational convenience. The inner wall of the movable block 316 has several anti-slip grooves 317 evenly distributed on it. These grooves increase friction between the user's hand and the movable block 316, preventing misalignment during movement. A guide block 312 is fixedly connected to the end of the limiting rod 311 furthest from the fixed ring 301.The guide block 312 can limit the position of the limiting rod 311, allowing personnel to easily slide the limiting rod 311 into the inner wall of the positioning hole 303. The rotating plate 306 is made of stainless steel. Stainless steel has high strength and good wear resistance, which can prevent the rotating plate 306 from deforming during short-term use. The working principle of the high-temperature resistant weldable reducing assembly provided by this utility model is as follows: When personnel need to connect and install the connecting pipe 2 onto the reducing assembly body 1, they can first move the connecting pipe 2. The connecting pipe 2 drives the limiting ring 309, the fixing ring 301, and the rotating ring 313 to move closer to the reducing assembly body 1. The limiting ring 309 and the rotating ring 313 drive the coil spring 310 to move closer to the reducing assembly body 1. The fixing ring 301 drives the three positioning blocks 318, the three fixing blocks 314, and the three limiting rods 311 to move closer to the reducing assembly body 1. The limiting rods 311 drive the guide... Block 312 moves towards the body 1 of the reducing assembly, positioning block 318 drives protective pad 319 to move towards the body 1 of the reducing assembly, and rotating ring 313 drives three moving blocks 316 and three locking strips 320 to move towards the body 1 of the reducing assembly. Moving blocks 316 allow personnel to easily rotate rotating ring 313, improving ease of operation. The guide block 312 and limiting rod 311 slide into the inner wall of positioning hole 303, causing the connecting pipe 2 to abut against the body 1 of the reducing assembly. The guide block 312 limits the limiting rod 311, allowing personnel to easily position the limiting rod 311. 1. The slide block 316 slides into the inner wall of the positioning hole 303. Then, the operator rotates the three moving blocks 316, which in turn rotates the moving ring. The moving ring rotates the three locking strips 320, and the moving ring also rotates the coil spring 310. At this time, the fixing block 314 slides on the inner wall of the auxiliary groove 315 until it abuts against the other side wall of the auxiliary groove 315. Then, the operator rotates the rotating plate 306, which in turn rotates the connecting block 307 until it abuts against the protective pad 319. The protective pad 319 protects the rotating plate 306 and prevents it from contacting the positioning block 316. 18. Direct contact occurs, and when the person releases the moving block 316, the coil spring 310 rebounds, causing the locking strip 320 to rotate towards the positioning groove 308 until the locking strip 320 slides into the inner wall of the positioning groove 308. At this time, the fixing block 314 abuts against the side wall of the auxiliary groove 315. The anti-slip groove 317 opened on the inner wall of the moving block 316 can increase the friction between the person's hand and the moving block 316, which can prevent the person from misaligning during the movement of the moving block 316. The stainless steel plate of the rotating plate 306 has high strength and good wear resistance, which can prevent the rotating plate 306 from deforming during short-term use.
