Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion pipeline technology, specifically an anti-corrosion pipeline that is easy to disassemble and assemble. Background Technology

[0002] Corrosion-resistant pipelines are steel pipelines treated with special processes to prevent or slow down chemical, electrochemical, or microbial corrosion, and are widely used in petroleum, chemical, and natural gas industries.

[0003] The utility model with announcement number CN219317877U discloses an easy-to-disassemble anti-corrosion pipe, including two pipes and a connecting pipe connecting the two pipes. Both ends of the connecting pipe are provided with connectors. The pipes are sleeved on the connectors. A fixing plate is installed on the pipe. A connecting groove is opened on the fixing plate. A movable rod is hinged to the connecting pipe by a pin.

[0004] The above technical solution, by rotating the movable rod to the inside of the connecting groove, adjusts the spring of the plate to create a squeezing effect between the movable plate and one side of the fixed plate, thus quickly completing the fixed installation of the pipe. When disassembly is required, pulling the movable plate to compress the spring away from the fixed plate causes the movable rod to rotate out of the connecting groove, thus quickly releasing the connection between the connecting pipe and the pipe, replacing the previous connection method using flanges and bolts, simplifying the entire disassembly and assembly process, and saving time and effort. However, when installing or disassembling two pipes, the combination and fixation using four movable rods requires multiple repeated operations, and the gap between the connecting pipe and the pipe is not tightly sealed, which may lead to leakage during long-term liquid transportation. It does not increase the sealing of disassembly and installation, nor does it reduce the number of rotation and tightening operations. Utility Model Content

[0005] The purpose of this utility model is to provide a corrosion-resistant pipe that is easy to assemble and disassemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A corrosion-resistant pipe that is easy to assemble and disassemble includes a pipe, wherein limiting rings are provided on the outer wall of the pipe near both ends, an annular groove is provided on the left end of the pipe, a plug is provided on the right end of the pipe, and a connecting component that can be inserted and limited is provided between two adjacent pipes.

[0008] The connecting assembly includes two symmetrical connecting plates. On the opposite side of the connecting plates, there are limit grooves corresponding to the limit ring. Both ends of the connecting plates are provided with protrusions, and each protrusion is provided with a pin hole. The protrusion at the end of the upper connecting plate is provided with a pin, and the outer end wall of the protrusion at the end of the lower connecting plate is provided with a positioning pin for pin positioning.

[0009] Furthermore, the inner surface of the limiting ring is tightly fitted and bonded to the outer wall of the pipe, and a sealing gasket is provided on the opposite side of each of the two limiting rings, and the sealing gasket is bonded and fixed to the limiting ring.

[0010] In this invention, the installation of the limiting ring increases the force point, so that when two adjacent pipes are combined, the two limiting rings cooperate, the connecting components are pressed to increase the stability of the combination, and the two sealing gaskets increase the sealing performance of the connection components.

[0011] Specifically, the insert and the pipe are integrally formed. A second slot is provided on the outer wall of the insert, and a rubber ring is fitted on the second slot. The width of the outer wall of the insert is adapted to the width of the inner wall of the annular groove. A first slot is provided on the inner wall of the annular groove at the position corresponding to the rubber ring.

[0012] In this invention, the insert and the annular groove are tightly fitted together, and two adjacent pipes are tightly fitted together. The insert on one pipe is fitted with the annular groove on the other pipe, and the inner surface of the rubber ring is tightly fitted with the inner wall of the second groove, while the outer surface of the rubber ring is tightly fitted with the inner wall of the first groove. With the cooperation of the rubber ring, the sealing performance of the insertion between the insert and the annular groove is increased, and the impact of leakage at the pipe connection is reduced.

[0013] It should be noted that the width of the inner wall of the limiting groove is adapted to the total thickness when the two limiting rings and two sealing gaskets are tightly fitted, and the protrusion and the connecting plate are integrally formed.

[0014] In this invention, two limiting rings are engaged with corresponding sealing gaskets and limiting grooves to achieve the combination and fixation of two connecting plates and two adjacent pipes, thereby increasing the stability of the installation.

[0015] Furthermore, the lower surface of the protrusion at the end of the upper connecting plate is symmetrically provided with cylinders, and the upper surface of the protrusion at the end of the lower connecting plate is provided with a circular hole corresponding to the cylinder.

[0016] In this invention, the cylinder and the corresponding protrusion are integrally formed, and the cylinder and the round hole are inserted and matched, which helps the protrusions on the ends of the upper and lower connecting plates to be stably inserted and installed, and increases the stability of the splicing between the two connecting plates.

[0017] Specifically, a sliding hole is provided on the outer wall of the protrusion at the end of the connecting plate located below, corresponding to the end of the positioning pin, and a movable groove communicating with the pin hole is provided at the inner end of the sliding hole.

[0018] In this invention, the positioning pin is inserted into the sliding hole, and with the cooperation of the movable groove, the inner end of the positioning pin can slide and retract in the movable groove, which facilitates the fixed position of the pin.

[0019] It is worth adding that the positioning pin has a positioning post at its end, and a ring is provided on the outer wall of the positioning post at the position corresponding to the movable groove. A spring is provided on the outer wall of the ring, one end of the spring is bonded and fixed to the ring, and the other end of the spring is bonded and fixed to the bottom of the movable groove. A second pull ring is provided on the outer wall of the positioning pin.

[0020] In this invention, the outer diameter of the ring is adapted to the inner diameter of the movable groove. The ring provides a point of force to facilitate the connection of one end of the spring, and the second pull ring provides a point of force to facilitate the horizontal pulling and engaging of the positioning pin.

[0021] Furthermore, the bottom of the pin is provided with a pin post, and the pin post is provided with a insertion hole corresponding to the positioning post. The pin and the pin post are integrally formed.

[0022] In this utility model, the pin is inserted into the pin hole, and with the cooperation of the insertion hole, the positioning pin passes through the movable groove and extends into the insertion hole, so as to realize the positioning pin and the pin cross fixation, thereby realizing the combination and fixation of the two connecting plates, and realizing the tight combination and fixation of the two pipes (1), increasing the sealing stability of the connection.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. This utility model facilitates the combined connection of two adjacent pipes by setting a plug and an annular groove on the pipe. The rubber ring increases the sealing between the plug and the annular groove. The connecting assembly is formed by two connecting plates fitting tightly together, and the limiting rings at the ends of the two pipes are inserted to limit the connection, increasing the stability of the pipe assembly. The protrusions fit into the cylinder and the hole to achieve a stable connection between the two connecting plates. The positioning pins fit into the plug to achieve average stability between the two connecting plates. The two positioning pins retract to facilitate the removal of the plug, thereby enabling the connecting plates to separate quickly, the two pipes to separate, and the plug to disengage from the annular groove, facilitating the disassembly and removal of the pipes.

[0025] 2. This utility model increases the sealing performance of the joint between two pipes by setting a sealing gasket. The rubber ring initially increases the sealing performance, and the sealing gasket provides a secondary sealing fit. The positioning pin on the connecting plate retracts and fits in the movable groove with the help of the spring. When the pin needs to be positioned, the spring returns to its initial position, and the positioning pin extends into the insertion hole to fix the pin position. When separation is required, the ring is pulled, the spring is compressed in the movable groove, the end of the positioning pin separates from the insertion hole, and the pin is taken out from the pin hole, realizing quick disassembly and avoiding the need for multiple bolt fixation, which increases the cumbersomeness of operation.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-7 This embodiment provides a technical solution:

[0038] A corrosion-resistant pipe that is easy to assemble and disassemble includes a pipe 1. A limiting ring 10 is provided on the outer wall of the pipe 1 near the edges of both ends. The inner ring surface of the limiting ring 10 is tightly fitted and bonded to the outer wall surface of the pipe 1. A sealing gasket 100 is provided on the opposite side of the two limiting rings 10. The sealing gasket 100 is bonded and fixed to the limiting ring 10.

[0039] In this utility model, the installation of the limiting ring 10 increases the force point, so that when two adjacent pipes 1 are combined, the two limiting rings 10 cooperate, the connecting component 2 presses to increase the stability of the combination, and the two sealing gaskets 100 cooperate to increase the sealing performance of the connection component 2.

[0040] Furthermore, an annular groove 11 is provided at the left end of the pipe 1, and a plug 12 is provided at the right end of the pipe 1. The plug 12 and the pipe 1 are integrally formed. A second slot 120 is provided on the outer wall of the plug 12, and a rubber ring 121 is fitted on the second slot 120. The width of the outer wall of the plug 12 is adapted to the width of the inner wall of the annular groove 11. A first slot 110 is provided on the inner wall of the annular groove 11 at the position corresponding to the rubber ring 121.

[0041] In this invention, the insert 12 and the annular groove 11 are tightly inserted and fitted together, and two adjacent pipes 1 are tightly fitted together. The insert 12 on one pipe 1 is inserted and fitted together with the annular groove 11 on the other pipe 1, and the inner ring surface of the rubber ring 121 is tightly inserted with the inner wall surface of the second slot 120, and the outer ring surface of the rubber ring 121 is tightly fitted with the inner wall surface of the first slot 110. With the cooperation of the rubber ring 121, the sealing performance of the insertion of the insert 12 and the annular groove 11 is increased, and the leakage at the connection of the pipe 1 is reduced.

[0042] Specifically, the width of the inner wall of the limiting groove 200 is adapted to the total thickness when the two limiting rings 10 and the two sealing gaskets 100 are tightly fitted together, and the protrusion 21 and the connecting plate 20 are integrally formed structures.

[0043] In this utility model, two limiting rings 10 are engaged with corresponding sealing gaskets 100 and limiting grooves 200 to achieve the combination and fixation of two connecting plates 20 and two adjacent pipes 1, thereby increasing the stability of the installation.

[0044] Secondly, a pluggable and limitable connecting component 2 is provided between two adjacent pipes 1;

[0045] It should be noted that the connecting assembly 2 includes two symmetrical connecting plates 20. On the opposite side of the connecting plates 20, there are limit grooves 200 corresponding to the limit ring 10. Both ends of the connecting plates 20 are provided with protrusions 21. The lower surface of the protrusion 21 at the end of the upper connecting plate 20 is symmetrically provided with cylinders 211. The upper surface of the protrusion 21 at the end of the lower connecting plate 20 is provided with a circular hole 212 corresponding to the cylinder 211.

[0046] In this invention, the cylinder 211 and the corresponding protrusion 21 are integrally formed. The cylinder 211 and the circular hole 212 are inserted and matched, which helps the protrusion 21 on the ends of the upper and lower connecting plates 20 to be stably inserted and installed, and increases the stability of the splicing between the two connecting plates 20.

[0047] Furthermore, each of the protrusions 21 has a pin hole 210, and each of the protrusions 21 at the upper end of the connecting plate 20 has a pin 22, and each of the protrusions 21 at the lower end of the connecting plate 20 has a positioning pin 23 inserted into the outer end wall for positioning the pin 22.

[0048] Specifically, a sliding hole 213 is provided on the outer wall of the protrusion 21 at the end of the lower connecting plate 20, corresponding to the end of the positioning pin 23. A movable groove 214 communicating with the pin hole 210 is provided at the inner end of the sliding hole 213.

[0049] In this invention, the positioning pin 23 is inserted into the sliding hole 213, and with the cooperation of the movable groove 214, the inner end of the positioning pin 23 can slide and retract in the movable groove 214, which facilitates the fixed position of the pin 22.

[0050] It is worth adding that a positioning post 230 is provided at the end of the positioning pin 23, and a ring 231 is provided on the outer wall of the positioning post 230 at the position corresponding to the movable groove 214. A spring 232 is provided on the outer wall of the ring 231. One end of the spring 232 is bonded and fixed to the ring 231, and the other end of the spring 232 is bonded and fixed to the bottom of the movable groove 214. A second pull ring 233 is provided on the outer wall of the positioning pin 23.

[0051] In this utility model, the outer diameter of the ring 231 is adapted to the inner diameter of the movable groove 214. The ring 231 provides a force point to facilitate the connection of one end of the spring 232. The second pull ring 233 provides a force point to facilitate the horizontal pulling of the positioning pin 23.

[0052] Furthermore, the bottom of the pin 22 is provided with a pin post 220, and the pin post 220 is provided with a insertion hole 221 corresponding to the positioning post 230. The pin 22 and the pin post 220 are integrally formed.

[0053] In this utility model, the pin 220 is inserted into the pin hole 210, and with the cooperation of the insertion hole 221, the positioning pin 230 passes through the movable groove 214 and extends into the insertion hole 221, so that the positioning pin 230 and the pin 220 are cross-fixed, thereby realizing the combination and fixation of the two connecting plates 20, and realizing the tight combination and fixation of the two pipes 1, increasing the sealing stability of the connection.

[0054] In this embodiment, the easy-to-disassemble anti-corrosion pipe is used by first fixing the insert 12 to the pipe 1. The positioning pin 230 with the ring 231 and the positioning pin 23 are installed in the movable groove 214. One end of the spring 232 is bonded to the ring 231 and the other end is bonded to the inner wall of the movable groove 214. The insert pin 22 with the pin 220 is installed in the pin hole 210 of the connecting plate 20 located above.

[0055] When two adjacent pipes 1 are installed together, the rubber ring 121 is inserted into the second groove 120 on the corresponding insert post 12. The insert post 12 on one pipe 1 is inserted into the annular groove 11 on the other pipe 1. The outer end of the insert post 12 is inserted into the annular groove 11, and the outer end of the insert post 12 is tightly fitted with the inner wall of the annular groove 11. The outer ring of the rubber ring 121 is tightly inserted into the inner wall of the first groove 110. Then, the connecting plate 20 is snapped into the junction of the two pipes 1. The limiting groove 200 is tightly inserted into the two limiting rings 10, and the outer wall of the sealing gasket 100 is tightly fitted with the inner wall of the limiting groove 200. The protrusions 21 on the ends of the two connecting plates 20 are close to each other, and the cylinder 211 is tightly fitted into the corresponding groove 120. The corresponding round hole 212 is inserted to achieve stable installation between the two connecting plates 20. The second pull ring 233 is pulled first to compress the spring 232, and the positioning post 230 is stored in the movable groove 214. Then, the pin 22 is passed through the pin hole 210 in the upper connecting plate 20 to the pin hole 210 in the lower connecting plate 20 through the first pull ring 222. When the insertion hole 221 on the pin 220 corresponds to the sliding hole 213, the second pull ring 233 is released. Under the elastic force of the spring 232, the positioning post 230 extends into the insertion hole 221 to fix the position of the pin 220 in the pin hole 210, thereby achieving the combination and fixation between the two connecting plates 20 and increasing the stability of the splicing installation between the two pipes 1.

[0056] When disassembly is required, pull the two positioning pins 230 outward through the second pull ring 233. The inner end of the positioning pin 230 disengages from the insertion hole 221. Then, remove the pin 22 from the protrusion 21 through the first pull ring 222, which facilitates the quick separation of the two connecting plates 20. Then, use the friction force greater than that between the rubber ring 121 and the first slot 110 to separate the two pipes 1, which facilitates the quick disassembly of the pipes 1. With the cooperation of the sealing gasket 100 and the rubber ring 121, the junction of the pipes 1 is sealed in a double layer to reduce the impact of leakage. The two positioning pins 23 can be quickly pulled out to separate and remove the pin 22, and quickly separate or install the connecting plates 20. The operation is simple and convenient, and there is no need to repeatedly tighten the bolts to fix the position.
