Description

Technical Field

[0001] This utility model relates to the technical field of vacuum fusion-bonded corrosion-resistant and wear-resistant material tubes, specifically to a corrosion-resistant vacuum fusion-bonded corrosion-resistant and wear-resistant material tube. Background Technology

[0002] Vacuum-fused corrosion-resistant and wear-resistant tubing is manufactured by high-temperature centrifugal casting or vacuum powder metallurgy within a steel outer tube using NiCrBSi or CrFe alloy powder. This manufacturing process gives the inner and outer surfaces of the tubing a unique microstructure: the outer tube has a pearlitic or martensitic microstructure, while the inner surface has a martensitic or martensitic-carbide microstructure.

[0003] When connecting vacuum-fused corrosion-resistant and wear-resistant pipes, flange connections are often used. This requires tightening multiple bolts in sequence to clamp and seal the rubber sealing rings at the connection points, which is a rather cumbersome operation.

[0004] Therefore, it is necessary to invent a corrosion-resistant vacuum-fused corrosion-resistant and wear-resistant material tube to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion-resistant vacuum-fused corrosion-resistant and wear-resistant material tube. The upper vacuum-fused material tube and the connecting component cooperate to achieve a simple connection, thereby solving the problem that the existing technology requires tightening multiple bolts in sequence to clamp and seal the rubber sealing ring at the connection point, which is a relatively cumbersome operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant vacuum-fused corrosion-resistant and wear-resistant material tube, comprising an upper vacuum-fused material tube, a lower vacuum-fused material tube disposed below the upper vacuum-fused material tube, and connecting components disposed on opposite sides of the upper and lower vacuum-fused material tubes. Each connecting component includes a connecting sleeve fixedly connected to the outside of the upper vacuum-fused material tube, a sealing groove being formed at the bottom end of the connecting sleeve, and several sets of upper limit blocks fixedly connected to the bottom end of the connecting sleeve. A second snap-fit ​​collar is fixedly connected to the inner wall of the upper vacuum fusion tube. A first snap-fit ​​collar is located below the second snap-fit ​​collar. The first snap-fit ​​collar is fixedly connected to the inner wall of the lower vacuum fusion tube. The bottom inner side of the first snap-fit ​​collar is threaded, and the top outer side of the second snap-fit ​​collar is threaded. The outer diameter of the second snap-fit ​​collar is the same as the inner diameter of the first snap-fit ​​collar. The initial connection between the upper and lower vacuum fusion tubes is achieved by inserting and rotating the first and second snap-fit ​​collars, thus saving subsequent steps.

[0007] Preferably, a connecting sleeve two is provided on the outer side of the snap-fit ​​ring one and the connecting sleeve two is fixedly connected to the outer side wall of the lower vacuum fusion tube. A sealing rubber ring is fixedly connected to the top end of the connecting sleeve two and the sealing rubber ring is positioned corresponding to the sealing groove. The sealing of the upper vacuum fusion tube and the lower vacuum fusion tube is achieved by the cooperation of the sealing rubber ring and the sealing groove.

[0008] Preferably, the bottom end of the connecting sleeve one is fixedly connected with several sets of upper limit blocks, the upper limit blocks are evenly distributed around the snap ring two, and the top of the upper limit block is provided with an upper limit groove, so that the upper limit block can cooperate with subsequent parts.

[0009] Preferably, a number of lower limit blocks are fixedly connected to the top of the connecting sleeve 2. The lower limit blocks are evenly distributed around the snap-fit ​​collar 1. A lower limit groove is provided at the bottom of the lower limit block so that the lower limit block corresponds to the upper limit block.

[0010] Preferably, the lower limiting groove and the upper limiting block have the same shape, and the lower limiting block and the upper limiting groove have the same shape. By interlocking the lower limiting block and the upper limiting block, the distance between the upper vacuum fusion tube and the lower vacuum fusion tube is further reduced, so that the sealing rubber ring fills the interior of the sealing groove to enhance the seal.

[0011] Preferably, a lower ceramic block is fixedly connected to the outer side wall of the second connecting sleeve, and an upper ceramic block is fixedly connected to the outer side wall of the first connecting sleeve. Several sets of mounting grooves are opened on the outer side of both the upper and lower ceramic blocks, and rubber strips are installed inside the mounting grooves. The stability of the connection between the upper and lower vacuum fusion tubes is improved by the cooperation of the upper and lower ceramic blocks, and the wear resistance is improved by the rubber strips.

[0012] Preferably, the inner walls of the upper vacuum fusion tube and the lower vacuum fusion tube are fixedly connected to a protective layer, the inner side of the protective layer is fixedly connected to an anti-corrosion coating, and the inner wall of the anti-corrosion coating is fixedly connected to a neoprene rubber pad, thereby further improving the anti-corrosion performance of the structure.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. By cooperating with the upper vacuum fusion tube and the connecting component, and by using the engagement of snap-fit ​​sleeve one and snap-fit ​​sleeve two to rotate after insertion, the connection of connecting sleeve one and connecting sleeve two is achieved, thereby connecting the upper vacuum fusion tube and the lower vacuum fusion tube. When the connection is successful, rotate the lower limit block or the upper limit block to make the lower limit block engage with the upper limit groove, and the lower limit groove engage with the upper limit block, thereby strengthening the connection and further reducing the gap between the upper vacuum fusion tube and the lower vacuum fusion tube, so that the sealing rubber ring fills the interior of the sealing groove to enhance the sealing performance, thus achieving simple connection and sealing.

[0015] 2. Through the cooperation of components such as the upper ceramic block, lower ceramic block, and protective layer, rubber strips are installed using the mounting grooves on the surfaces of the upper and lower ceramic blocks. The rubber strips, along with the upper and lower ceramic blocks, protect the connection between the lower and upper vacuum fusion tubes from external wear. At the same time, the protective layer, anti-corrosion coating, and neoprene rubber pads work together to protect the anti-corrosion coating and enhance the corrosion resistance of the upper and lower vacuum fusion tubes.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5The diagram shows a corrosion-resistant vacuum-fused corrosion-resistant and wear-resistant material tube, comprising an upper vacuum-fused material tube 1, a lower vacuum-fused material tube 101 disposed below the upper vacuum-fused material tube 1, and connecting components 2 disposed on opposite sides of the upper vacuum-fused material tube 1 and the lower vacuum-fused material tube 101. Each connecting component 2 includes a connecting sleeve 201 fixedly connected to the outside of the upper vacuum-fused material tube 1, a sealing groove 209 formed at the bottom end of the connecting sleeve 201, and several sets of upper limit blocks 207 fixedly connected to the bottom end of the connecting sleeve 201. A snap-fit ​​collar 206 is fixedly connected to the inner wall of the upper vacuum-fused material tube 1, and a snap-fit ​​collar 203 is disposed below the snap-fit ​​collar 206, fixedly connected to the inner wall of the lower vacuum-fused material tube 101. The inner bottom of the snap-fit ​​collar 203 is threaded, and the outer top of the snap-fit ​​collar 206 is threaded. The outer diameter of the snap-fit ​​collar 206 is the same as the inner diameter of the snap-fit ​​collar 203. The insertion and rotation of the snap-fit ​​collar 203 and the snap-fit ​​collar 206 achieve the initial connection between the upper vacuum fusion tube 1 and the lower vacuum fusion tube 101, saving subsequent steps. A connecting sleeve 210 is provided on the outer side of the snap-fit ​​collar 203 and is fixedly connected to the outer wall of the lower vacuum fusion tube 101. A sealing rubber ring 202 is fixedly connected to the top of the connecting sleeve 210, and the sealing rubber ring 202 corresponds to the sealing groove 209. The upper vacuum fusion tube 1 is connected to the connecting sleeve 206 by the cooperation of the sealing rubber ring 202 and the sealing groove 209. The vacuum fusion tube 1 and the lower vacuum fusion tube 101 are sealed. Several sets of upper limit blocks 207 are fixedly connected to the bottom end of the connecting sleeve 201. The upper limit blocks 207 are evenly distributed around the snap-fit ​​collar 206. Upper limit grooves 208 are formed on the top of the upper limit blocks 207, allowing them to mate with subsequent parts. Several sets of lower limit blocks 204 are fixedly connected to the top end of the connecting sleeve 210. The lower limit blocks 204 are evenly distributed around the snap-fit ​​collar 203. Lower limit grooves 205 are formed on the bottom of the lower limit blocks 204, ensuring that the lower limit blocks 204 correspond to the upper limit blocks 207. The lower limit grooves 205 and upper limit blocks 207 have the same shape, and the lower limit blocks 204 and upper limit grooves 208 have the same shape. The interlocking of the lower limit block 204 and the upper limit block 207 further reduces the distance between the upper vacuum fusion tube 1 and the lower vacuum fusion tube 101, thereby filling the sealing groove 209 with the sealing rubber ring 202 to enhance the seal. Through the cooperation between the upper vacuum fusion tube 1 and the connecting assembly 2, the interlocking sleeve 1 203 and the interlocking sleeve 206 allow the tube to rotate after insertion, thus connecting the connecting sleeve 1 201 and the connecting sleeve 210. This connects the upper vacuum fusion tube 1 and the lower vacuum fusion tube 101. Upon successful connection, rotating the lower limit block 204 or the upper limit block 207 causes the lower limit block 204 to interlock with the upper limit groove 208, and the lower limit groove 205 to interlock with the upper limit block 207.This strengthens the connection and further reduces the distance between the upper vacuum fusion tube 1 and the lower vacuum fusion tube 101, allowing the sealing rubber ring 202 to fill the interior of the sealing groove 209 to enhance sealing performance, thus achieving a simple connection and seal.

[0026] Refer to the instruction manual appendix Figure 1-5 A lower ceramic block 4 is fixedly connected to the outer wall of connecting sleeve 210, and an upper ceramic block 3 is fixedly connected to the outer wall of connecting sleeve 1 201. Several sets of mounting grooves are provided on the outer sides of both the upper ceramic block 3 and the lower ceramic block 4, and rubber strips are installed inside the mounting grooves. The cooperation between the upper ceramic block 3 and the lower ceramic block 4 improves the stability of the connection between the upper vacuum fusion tube 1 and the lower vacuum fusion tube 101, and the rubber strips enhance its wear resistance. A protective layer 5 is fixedly connected to the inner wall of the upper vacuum fusion tube 1 and the lower vacuum fusion tube 101. An anti-corrosion coating 6 is fixedly connected to the inner side of the protective layer 5. A neoprene rubber pad 7 is fixedly connected to further improve the corrosion resistance of the structure. Through the cooperation of the upper ceramic block 3, the lower ceramic block 4, the protective layer 5, and other parts, the rubber strip is installed using the mounting grooves on the surfaces of the upper ceramic block 3 and the lower ceramic block 4. The rubber strip, together with the upper ceramic block 3 and the lower ceramic block 4, protects the connection between the lower vacuum fusion tube 101 and the upper vacuum fusion tube 1 from external wear. At the same time, the cooperation of the protective layer 5, the anti-corrosion coating 6, and the neoprene rubber pad 7 protects the anti-corrosion coating 6 to enhance the corrosion resistance of the upper vacuum fusion tube 1 and the lower vacuum fusion tube 101.

[0027] The working principle of this practical application is as follows:

[0028] Refer to the instruction manual appendix Figure 1-5When connecting the upper vacuum fusion tube 1 to the lower vacuum fusion tube 101, firstly, engage and insert the first snap-fit ​​collar 203 and the second snap-fit ​​collar 206, then rotate to connect the first connecting collar 201 and the second connecting collar 210, and allow the sealing rubber ring 202 to enter the sealing groove 209, thereby connecting the upper vacuum fusion tube 1 to the lower vacuum fusion tube 101. Upon successful connection, rotate the upper vacuum fusion tube 1 or the lower vacuum fusion tube 101 to move the lower limit block 204 or the upper limit block 207, causing the lower limit block 204 to engage with the upper limit groove 208, and the lower limit groove 205 to engage with the upper limit block 207, thus strengthening the connection. The gap between the upper vacuum fusion tube 1 and the lower vacuum fusion tube 101 is reduced in one step, so that the sealing rubber ring 202 fills the interior of the sealing groove 209 to enhance the sealing performance, thus achieving a simple connection and seal. After the connection is completed, the rubber strip is installed using the mounting grooves on the surfaces of the upper ceramic block 3 and the lower ceramic block 4. The rubber strip, the upper ceramic block 3, and the lower ceramic block 4 are used to protect the connection between the lower vacuum fusion tube 101 and the upper vacuum fusion tube 1 from external wear. At the same time, the protective layer 5, the anti-corrosion coating 6, and the neoprene rubber pad 7 are used to protect the anti-corrosion coating 6 and enhance the corrosion resistance of the upper vacuum fusion tube 1 and the lower vacuum fusion tube 101.
