Description

A pressure detection device for sucralose delivery pipelines Technical Field

[0001] This utility model belongs to the field of pipeline pressure detection technology, specifically a pressure detection device for sucralose delivery pipelines. Background Technology

[0002] The production process requires the transportation of liquid raw materials through a closed pipeline system. Due to the requirements of the production process, the pipelines typically need to withstand a working pressure of 0.3-0.8 MPa, and the medium is corrosive. Long-term pressure load and fluid pulsation impact can easily lead to fatigue cracks at the pipeline welds, which can cause leakage accidents in severe cases. This not only affects the continuity of production, but may also cause raw material contamination and safety risks.

[0003] Currently, the industry generally uses magnetic particle testing instruments to conduct regular inspections of welds. However, when using magnetic particle testing instruments, workers need to hold the instrument and inspect along the weld. When workers hold the instrument, it tends to sway from side to side, which is time-consuming and physically demanding for them. Summary of the Invention

[0004] This invention provides a pressure detection device for sucralose delivery pipelines to address the deficiencies in existing technologies.

[0005] This utility model is achieved through the following technical solution:

[0006] A pressure testing device for a sucralose delivery pipeline includes a detachable, semi-circular support ring and a connecting ring that are adsorbed onto both sides of the pipeline. The support ring and the connecting ring are joined together to form a circular ring. Both the support ring and the circular ring have arc-shaped grooves on their front sides, forming a circle. The two side walls of the arc-shaped grooves extend outward into limiting grooves. Rollers that roll along the limiting grooves are provided in the limiting grooves. One end of a connecting rod is rotatably connected to the front end of the rollers via a bearing. The other end of the connecting rod passes through the arc-shaped grooves and is fixedly connected to the side of a magnetic particle flaw detector. The detection end of the magnetic particle flaw detector faces the weld seam.

[0007] In use, the magnetic particle inspection instrument is first positioned at the weld seam. Then, based on the detection of the magnetic particle inspection instrument, the support ring and connecting ring are placed on the pipe and attracted to it. The support ring and connecting ring are joined to form a ring. The magnetic particle inspection instrument is then moved. Since the magnetic particle inspection instrument is fixedly connected to the connecting rod, and the connecting rod is rotatably connected to the roller, the roller is locked in the limiting groove. Therefore, the limiting groove can support it. The operator only needs to hold the magnetic particle inspection instrument, which can effectively prevent the magnetic particle inspection instrument from swaying left and right, thus saving the operator's physical strength and time.

[0008] Preferably, two support rings and two connecting rings are provided, with both support rings connected to the corresponding side of the magnetic particle flaw detector via connecting rods. Providing support rings on both sides ensures stable support for the magnetic particle flaw detector.

[0009] Preferably, several first magnets are evenly fixedly arranged along the inner wall of the support ring and the connecting ring. The first magnets can be attracted to the pipe to fix the support ring and the connecting ring.

[0010] Preferably, the inner end face of the first magnet is an arc-shaped surface that fits against the outer surface of the pipe, thereby enabling better adsorption between the first magnet and the pipe.

[0011] Preferably, the support ring has an arc-shaped groove on its end face, and an arc-shaped insert rod that mates with the arc-shaped groove is fixedly connected to the end face of the connecting pipe. When the support ring and the connecting ring are joined to form a ring, the arc-shaped insert rod is inserted into the corresponding arc-shaped groove. The engagement of the ring-shaped insert rod with the arc-shaped groove enables better engagement between the support ring and the connecting ring, thereby ensuring that the roller moves better from the limiting groove on the support ring to the limiting groove on the connecting ring.

[0012] Preferably, a second magnet is fixedly connected to the end of the arc-shaped insert, and an iron piece that attracts the second magnet is fixedly connected to the inner end of the arc-shaped groove. The attraction between the second magnet and the iron piece can achieve better fixation between the support ring and the connecting ring.

[0013] The beneficial effects of this utility model are as follows: By adsorbing the support ring and connecting ring onto the pipe and allowing the roller to roll in the limiting groove, the magnetic particle flaw detector can be limited, ensuring that the magnetic particle flaw detector can only rotate along the weld seam, avoiding its left and right swaying, and saving the time and effort spent by the staff to align the weld seam.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] A pressure testing device for a sucralose delivery pipeline, as shown in Figures 1 and 2, includes a detachable, semi-circular support ring 2 and a connecting ring 3 that are adsorbed onto both sides of a pipeline 1. The support ring 2 and the connecting ring 3 are joined together to form a circular ring. Both the support ring 2 and the circular ring have arc-shaped grooves 4 on their front sides, forming a circle. The two side walls of the arc-shaped grooves 4 extend outward into limiting grooves. Rollers 5 that roll along the limiting grooves are provided in the limiting grooves. One end of a connecting rod 11 is rotatably connected to the front end of the roller 5 via a bearing. The other end of the connecting rod 11 passes through the arc-shaped grooves 4 and is fixedly connected to the side of a magnetic particle inspection instrument 10. The detection end of the magnetic particle inspection instrument 10 faces the weld seam.

[0021] In use, the magnetic particle inspection instrument 10 is first positioned at the weld seam. Then, based on the detection of the magnetic particle inspection instrument 10, the support ring 2 and the connecting ring 3 are placed on the pipe 1, causing them to adhere to the pipe 1. The support ring 2 and the connecting ring 3 are joined to form a ring. The magnetic particle inspection instrument 10 is then moved. Since the magnetic particle inspection instrument 10 is fixedly connected to the connecting rod 11, and the connecting rod 11 is rotatably connected to the roller 5, the roller 5 is stuck in the limiting groove. Therefore, the limiting groove can provide support. The operator only needs to hold the magnetic particle inspection instrument 10, which can effectively prevent the instrument from wobbling from side to side, thus saving the operator's physical strength and time.

[0022] Two support rings 2 and two connecting rings 3 are provided, and both support rings 2 are connected to the corresponding sides of the magnetic particle flaw detector 10 via connecting rods 11. The support rings 2 on both sides can achieve stable support for the magnetic particle flaw detector 10.

[0023] Several first magnets 6 are uniformly fixed along the inner wall of the support ring 2 and the connecting ring 3. The inner end face of each first magnet 6 is an arc-shaped surface and fits against the outer side of the pipe 1.

[0024] The first magnet 6 can be attracted to the pipe 1 to fix the support ring 2 and the connecting ring 3. The inner end face of the first magnet 6 is arc-shaped and fits against the outer surface of the pipe 1, thereby achieving better adhesion between the first magnet 6 and the pipe 1.

[0025] The support ring 2 has an arc-shaped groove 9 on its end face, and an arc-shaped insert 8 that mates with the arc-shaped groove 9 is fixedly connected to the end face of the connecting pipe. When the support ring 2 and the connecting ring 3 are joined to form a ring, the arc-shaped insert 8 is inserted into the corresponding arc-shaped groove 9. The engagement of the ring insert 8 with the arc-shaped groove 9 enables better engagement between the support ring 2 and the connecting ring 3, thereby ensuring that the roller 5 moves better from the limiting groove on the support ring 2 to the limiting groove on the connecting ring 3.

[0026] The end of the arc-shaped insert 8 is fixedly connected to a second magnet 7, and the inner end of the arc-shaped groove 9 is fixedly connected to an iron piece that attracts the second magnet 7. The attraction between the second magnet 7 and the iron piece can achieve better fixation between the support ring 2 and the connecting ring 3.

[0027] The use of this application can limit the magnetic particle inspection instrument 10 by adsorbing the support ring 2 and the connecting ring 3 onto the pipe 1, and the roller 5 can roll in the limiting groove, ensuring that the magnetic particle inspection instrument 10 can only rotate along the weld seam, avoiding its left and right swaying, and saving the time and effort spent by the staff to align the weld seam.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
