Description

Technical Field

[0001] This utility model relates to the field of pipe elbow technology, and in particular to anti-collision and wear-resistant pipe elbow. Background Technology

[0002] An elbow is a pipe fitting that can connect two pipes with the same or different nominal diameters, allowing the pipeline to make turns of 90°, 45°, 180° and various other degrees. It can be divided into welded elbows, stamped elbows, push-formed elbows, cast elbows, butt-welded elbows, etc.

[0003] In existing technology, when pipe elbows are used, the liquid transported inside the pipe will continuously impact the bend inside the pipe. Under the action of large impact force over a long period of time, the bend of the pipe is prone to damage, resulting in a poor service life of the pipe elbow. Utility Model Content

[0004] This utility model proposes an anti-collision and wear-resistant pipe elbow to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-collision and wear-resistant pipe elbow, comprising a pipe body, both ends of which are fixedly installed with flanges, wherein the flanges are installed on the pipe body by bolts, and a protective device is provided inside the pipe body, the protective device comprising a bendable spiral guide tube, wherein the guide tube is detachably installed inside the pipe body, and the spiral guide tube can guide the fluid inside the pipe body into a spiral vortex.

[0006] The effect achieved by the above components is as follows: when the pipe needs to be used, the staff first moves the pipe to the installation position, and then the staff installs the pipe with bolts. When the fluid in the pipe passes through the spiral guide tube, the guide tube guides the fluid to form a spiral vortex, thereby reducing the impact of the fluid on the bend of the pipe.

[0007] Preferably, the protective device further includes two fixing rings, which are respectively fixedly connected to the openings at both ends of the tube body. The fixing rings have two symmetrical insertion holes inside. The two mounting plates are respectively fixedly connected to the two ends of the guide tube. Insert rods are slidably connected inside the two ends of the mounting plates, and the size of the insert rods is adapted to the size of the insertion holes.

[0008] The aforementioned components achieve the following effects: When the guide tube needs to be installed, the operator first moves the insert rod into the mounting plate. Then, the operator inserts the guide tube into the tube body. After the guide tube is fully inserted, the operator moves the mounting plate to a position parallel to the fixing ring. The operator then pulls the insert rod, which inserts into the hole of the fixing ring, thus securing the mounting plate and the guide tube. When the guide tube needs to be disassembled, the operator moves the insert rod out of the hole of the fixing ring, and then removes the guide tube. The guide tube installed with the protective device effectively guides the fluid in the tube body, preventing excessive fluid impact that could damage the tube body and reduce its lifespan.

[0009] Preferably, the protective device further includes an iron plate and a magnet, wherein the iron plate is fixedly connected to one end of the insertion rod, and the magnet is fixedly connected inside the insertion hole of the fixing ring, wherein the magnet and the iron plate attract each other.

[0010] The effect achieved by the above components is that when the insertion rod is inserted into the insertion hole of the fixing ring, the iron plate and the magnet stick together and attract each other, thereby fixing the insertion rod and preventing it from moving out of the insertion hole.

[0011] Preferably, the pull plate is fixedly installed on one side of the insertion rod, and the mounting plate has a reserved hole for the pull plate, wherein the pull plate is slidably adapted to the reserved hole.

[0012] The effect achieved by the above-mentioned components is to increase the contact area between the worker's hand and the insertion rod by setting up the pull plate, thereby making it easier for the worker to move the insertion rod.

[0013] Preferably, the two slide plates are fixedly connected to both sides of the plug rod, and the mounting plate has a groove for the slide plate, wherein the slide plate and the groove are slidably adapted to each other.

[0014] The effect achieved by the above components is that by moving the slide plate in the groove of the mounting plate, the direction of movement of the insertion rod is restricted, thus preventing the insertion rod from shaking.

[0015] Preferably, the pipe body is composed of a wear-resistant layer, a base layer, and a heat insulation layer. The wear-resistant layer is located inside the pipe body, the heat insulation layer is located outside the pipe body, and the base layer is located between the wear-resistant layer and the heat insulation layer.

[0016] The effect achieved by the above components is to enhance the overall wear resistance of the pipe body by setting a wear-resistant layer, thereby increasing the service life of the pipe body.

[0017] Preferably, the wear-resistant layer is a composite ceramic material.

[0018] The effect achieved by the above components is that the ceramic material has extremely high hardness and wear resistance, thereby improving the wear resistance of the tube body.

[0019] Preferably, the insulation layer is polyurethane foam.

[0020] The effect achieved by the above-mentioned components is that by setting up an insulation layer, the fluid inside the pipe is kept warm, while preventing workers from accidentally touching the pipe and thus avoiding burns.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] When installing the guide tube, the worker first moves the insert rod into the mounting plate. Then, the worker inserts the guide tube into the pipe body. Once the guide tube is fully inside, the worker moves the mounting plate to a position parallel to the fixing ring. The worker then pulls the insert rod, which inserts into the hole in the fixing ring, thus securing the mounting plate and guide tube. To remove the guide tube, the worker moves the insert rod out of the hole in the fixing ring, and then removes the guide tube. The guide tube, installed with the protective device, effectively guides the fluid within the pipe body, preventing excessive fluid impact that could damage the pipe body and reduce its lifespan.

[0029] Reference Figure 1-5As shown, this embodiment discloses an anti-collision and wear-resistant pipe elbow, including a pipe body 1. Flanges 2 are fixedly installed at both ends of the pipe body 1, and the flanges 2 are bolted to the pipe body 1. A protective device 3 is provided inside the pipe body 1. The protective device 3 includes a flexible spiral guide tube 33, which is detachably installed inside the pipe body 1. The spiral guide tube 33 guides the fluid inside the pipe body 1 into a spiral vortex. When the pipe body 1 needs to be used, the operator first moves the pipe body 1 to the installation location, and then installs the pipe body 1 using bolts. When the fluid in the pipe body 1 passes through the spiral guide tube 33, the guide tube 33 guides the fluid to form a spiral vortex, thereby reducing the impact of the fluid on the bend of the pipe body 1.

[0030] Reference Figure 1-5 As shown, the protective device 3 also includes two fixing rings 31, which are fixedly connected to the openings at both ends of the tube body 1. The fixing rings 31 have two symmetrical insertion holes 35 inside. Two mounting plates 32 are fixedly connected to the two ends of the guide tube 33. Insert rods 34 are slidably connected inside the two ends of the mounting plates 32. The size of the insert rods 34 is adapted to the size of the insertion holes 35. When the guide tube 33 needs to be installed, the worker first moves the insertion rod 34 into the interior of the mounting plate 32. Then, the worker inserts the guide tube 33 into the interior of the pipe body 1. After the guide tube 33 is fully inserted into the pipe body 1, the worker moves the mounting plate 32 to a position parallel to the fixing ring 31. The worker pulls the insertion rod 34, and the insertion rod 34 on the mounting plate 32 inserts into the insertion hole 35 of the fixing ring 31, thus fixing the mounting plate 32 and the guide tube 33. When the guide tube 33 needs to be disassembled, the worker moves the insertion rod 34 out of the insertion hole 35 of the fixing ring 31, and then removes the guide tube 33. The guide tube 33 installed by the protective device 3 achieves the effect of guiding the fluid in the pipe body 1, avoiding excessive fluid impact force, which could lead to damage to the pipe body 1 and a reduction in the service life of the pipe body 1.

[0031] Reference Figure 1-5As shown, the protective device 3 also includes: an iron plate 38 and a magnet 39. The iron plate 38 is fixedly connected to one end of the insertion rod 34, and the magnet 39 is fixedly connected inside the insertion hole 35 of the fixing ring 31, wherein the magnet 39 and the iron plate 38 attract each other. When the insertion rod 34 is inserted into the insertion hole 35 of the fixing ring 31, the iron plate 38 and the magnet 39 stick together and attract each other, achieving the effect of fixing the insertion rod 34 and preventing the insertion rod 34 from moving out of the insertion hole 35. A pull plate 36 is fixedly installed on one side of the insertion rod 34. The mounting plate 32 has a reserved hole 37 for the pull plate 36, wherein the pull plate 36 slides and adapts to the reserved hole 37. By setting the pull plate 36, the contact area between the worker's hand and the insertion rod 34 is increased, thereby facilitating the worker to move the insertion rod 34. Two sliding plates 310 are fixedly connected to both sides of the insertion rod 34. The mounting plate 32 has a groove 311 for the sliding plates 310, in which the sliding plates 310 slide and adapt to the groove 311. By moving the sliding plates 310 in the groove 311 of the mounting plate 32, the movement direction of the insertion rod 34 is restricted, preventing the insertion rod 34 from shaking.

[0032] Reference Figure 1-5 As shown, the pipe body 1 consists of a wear-resistant layer 11, a base layer 12, and a heat insulation layer 13. The wear-resistant layer 11 is located inside the pipe body 1, the heat insulation layer 13 is located on the outside of the pipe body 1, and the base layer 12 is located between the wear-resistant layer 11 and the heat insulation layer 13. By setting the wear-resistant layer 11, the overall wear resistance of the pipe body 1 is increased, thereby increasing the service life of the pipe body 1.

[0033] Reference Figure 1-5 As shown, the wear-resistant layer 11 is made of composite ceramic material. Ceramic material has extremely high hardness and wear resistance, thus improving the wear resistance of the pipe body 1. The insulation layer 13 is made of polyurethane foam. By setting the insulation layer 13, the fluid inside the pipe body 1 is kept warm, while also preventing workers from accidentally touching the pipe body 1 and thus avoiding burns.

[0034] Working principle: When the pipe body 1 needs to be used, the operator first moves the pipe body 1 to the installation position, and then installs the pipe body 1 with bolts. When the guide tube 33 needs to be installed, the operator first moves the insertion rod 34 through the pull plate 36. The pull plate 36 moves the insertion rod 34 into the interior of the mounting plate 32 through the reserved hole 37. Then, the operator inserts the guide tube 33 into the interior of the pipe body 1. After the guide tube 33 is fully inserted into the pipe body 1, the operator moves the mounting plate 32 to a position parallel to the fixing ring 31. The operator pulls the insertion rod 34 through the pull plate 36, and the insertion rod 34 on the mounting plate 32 is inserted into the insertion hole 35 of the fixing ring 31. At this time, the iron plate 38 and the magnet 39 adhere to each other and attract each other, achieving the effect of fixing the insertion rod 34. When the fluid in the tube 1 passes through the spiral guide tube 33, the guide tube 33 guides the fluid to form a spiral vortex, thereby reducing the impact of the fluid on the bend of the tube 1. When the guide tube 33 needs to be disassembled, the operator moves the insertion rod 34, and the insertion rod 34 is removed from the insertion hole 35 of the fixing ring 31. Then the guide tube 33 can be taken out. The guide tube 33 installed by the protective device 3 achieves the effect of guiding the fluid in the tube 1, avoiding excessive fluid impact force, which could lead to damage to the tube 1 and a reduction in the service life of the tube 1.
