Description

Technical Field

[0001] The utility model relates to the field of PE pipes, in particular to a spliced PE pipe. Background Technique

[0002] PE pipe is a kind of pipeline material made of polyethylene resin, which has excellent low-temperature resistance, and the lowest service temperature can reach -70 to -100 °C. It also has good chemical stability and can withstand the erosion of most acids and alkalis.

[0003] The Chinese utility model patent with the publication number of CN212131556U discloses a spliced PE pipe. This spliced PE pipe completes splicing by respectively installing a first connecting pipe and a second connecting pipe on two pipe bodies, and then using a connecting rod and a nut to lock the two connecting pipes.

[0004] However, this spliced PE pipe needs to lock the pipe body and the connecting pipe respectively, and then lock the two connecting pipes installed with the pipe body to complete splicing. The whole process is relatively cumbersome, the splicing speed is low, and it is easy to affect the project efficiency in the construction site.

[0005] Therefore, a spliced PE pipe is provided to solve the above problems. Content of the Utility Model

[0006] (1) Technical Problems to be Solved

[0007] The utility model provides a spliced PE pipe, aiming to solve the problem that the existing spliced PE pipe has a cumbersome splicing process, resulting in low splicing efficiency as proposed in the background technique.

[0008] (2) Technical Solutions

[0009] To achieve the above object, the utility model provides the following technical solution: a spliced PE pipe, comprising a splicing pipe and a connecting pipe.

[0010] In order to simplify the splicing method of the PE pipe, the connecting pipe includes an intermediate pipe and tapered pipes fixedly connected to both ends of the intermediate pipe for inserting into the ends of the splicing pipe. Wherein, a sealing member is provided outside the tapered pipe for sealing between the tapered pipe and the splicing pipe.

[0011] At least three sliders are fixedly connected to the inner sides of both ends of the splicing pipe and are distributed in a circular array.

[0012] In order to simplify the locking method of the connecting pipe and the splicing pipe, a row groove for guiding the moving path of the slider is axially opened on the side of the tapered head pipe near one end of the intermediate pipe along the axis of the intermediate pipe, and a locking groove for restricting the position of the slider is circumferentially opened at one end of the row groove near the intermediate pipe along the circumference of the tapered head pipe; through the tapered design of the tapered head pipe and the guiding and locking mechanisms of the row groove and the locking groove, the connection process between the splicing pipe and the connecting pipe becomes smoother and faster, significantly improving the splicing efficiency, and the connection can be completed without complex tools or equipment, with simple operation and reduced usage threshold.

[0013] Preferably, in order to ensure the sealing performance between the splicing pipe and the tapered head pipe, the sealing member includes a first sealing ring and a second sealing ring that are sleeved outside the tapered head pipe in parallel and are both fixedly connected to the outer wall of the tapered head pipe; through the first sealing ring and the second sealing ring sleeved in parallel, multiple sealing barriers are formed, significantly enhancing the sealing performance between the tapered head pipe and the splicing pipe, which is particularly important for pipeline systems that need to withstand high pressure or prevent the leakage of harmful substances.

[0014] Preferably, in order to ensure the effectiveness of the sealing ring, both the first sealing ring and the second sealing ring are made of elastic rubber material, and the outer diameters of the first sealing ring and the second sealing ring are slightly larger than the inner diameter of the splicing pipe; the first sealing ring and the second sealing ring made of elastic rubber material can closely fit on the inner wall of the splicing pipe to form a reliable sealing barrier, effectively preventing the leakage of fluid or gas. The elastic rubber material has good wear resistance and corrosion resistance, and can maintain a stable sealing effect for a long time in a harsh working environment, thereby extending the service life of the pipeline system.

[0015] Preferably, in order to increase the stability of the slider in the locking groove, one side of the locking groove near the intermediate pipe has an elastic pad for pressing the slider against the inner wall of the locking groove; through the action of the elastic pad, the slider is tightly locked in the locking groove, effectively preventing connection loosening or detachment caused by external forces or vibrations and other factors, significantly enhancing the connection stability between the connecting pipe and the splicing pipe. The use of the elastic pad can effectively reduce the friction and wear between the slider and the locking groove, extending the service life of the connecting piece. At the same time, the stable connection state also reduces the risk of pipeline system damage caused by connection loosening, further improving the overall life of the pipeline system.

[0016] Preferably, in order to improve the locking effect of the locking groove, the side of the locking groove away from the elastic pad has a clamping protrusion, and a clamping groove corresponding to the clamping protrusion is opened on the slider; through the cooperation of the clamping protrusion and the clamping groove, the slider is more firmly locked in the locking groove, effectively preventing connection loosening or detachment caused by external forces or vibrations and other factors, and significantly improving the connection stability.

[0017] Preferably, in order to facilitate the application of force by the staff during splicing, the outer wall of the intermediate pipe has friction lines.

[0018] (III) Beneficial effects

[0019] For this spliced PE pipe, through the tapered design of the tapered head pipe and the guiding and locking mechanisms of the row grooves and locking grooves, the connection process between the spliced pipe and the connecting pipe becomes smoother and faster, significantly improving the splicing efficiency, and the connection can be completed without complex tools or equipment, with simple operation and reduced usage threshold.

[0020] For this spliced PE pipe, through the cooperation of the convex card and the card slot, the slider is more firmly locked in the locking groove, effectively preventing loosening or falling off of the connection caused by external forces or vibrations and other factors, and significantly improving the stability of the connection.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] Please refer to Figures 1-4 , the present utility model provides a technical solution: a spliced PE pipe, including a splicing pipe 1 and a connecting pipe 2.

[0033] The connecting pipe 2 includes an intermediate pipe 21 and tapered pipes 22 fixedly connected to both ends of the intermediate pipe 21 for inserting into the ends of the splicing pipe 1. Among them, a sealing member for sealing between the tapered pipe 22 and the splicing pipe 1 is provided outside the tapered pipe 22.

[0034] At least three sliders 11 distributed in an annular array are fixedly connected to the inner sides of both ends of the splicing pipe 1.

[0035] A row groove 221 for guiding the moving path of the slider 11 is axially opened on the side of the tapered pipe 22 near one end of the intermediate pipe 21, and a locking groove 222 for restricting the position of the slider 11 is circumferentially opened at the end of the row groove 221 near the intermediate pipe 21 along the circumference of the tapered pipe 22.

[0036] During use, when the connection of the spliced PE pipe is required, first insert the tapered pipe 22 part of the connecting pipe 2 into the end of the splicing pipe 1. During this process, due to the tapered shape of the tapered pipe 22, it will smoothly guide and insert into the interior of the splicing pipe 1. As the tapered pipe 22 goes deeper, the sliders 11 inside the splicing pipe 1 will move along the row groove 221 opened on the side of the tapered pipe 22. When the tapered pipe 22 is completely inserted into the predetermined position of the splicing pipe 1, rotate the splicing pipe 1 or the connecting pipe 2 to make the sliders 11 move to the locking groove 222 at the end of the row groove 221 near the intermediate pipe 21. The design of the locking groove 222 is to restrict the further movement and retraction of the sliders 11, thereby ensuring the fixed connection between the splicing pipe 1 and the connecting pipe 2. Similarly, connect another splicing pipe 1 to the same connecting pipe 2 to complete the splicing. Through the tapered design of the tapered pipe 22 and the guiding and locking mechanisms of the row groove 221 and the locking groove 222, the connection process between the splicing pipe 1 and the connecting pipe 2 is made smoother and faster, significantly improving the splicing efficiency, and the connection can be completed without complex tools or equipment, with simple operation and reduced usage threshold.

[0037] Specifically, the sealing member includes a first sealing ring 225 and a second sealing ring 226 which are sleeved in parallel on the outside of the cone head tube 22 and are fixedly connected to the outer wall of the cone head tube 22. The first sealing ring 225 and the second sealing ring 226 are both made of elastic rubber, and the outer diameters of the first sealing ring 225 and the second sealing ring 226 are slightly larger than the inner diameter of the splicing tube 1. When the cone head tube 22 is inserted into the interior of the splicing tube 1, since the first sealing ring 225 and the second sealing ring 226 are both made of elastic rubber, they can produce a certain deformation under the action of external force. The outer diameter of each sealing ring is slightly larger than the inner diameter of the splicing tube 1. Therefore, when the cone head tube 22 is gradually inserted into the splicing tube 1, the first sealing ring 225 and the second sealing ring 226 will be subjected to the compression force from the inner wall of the splicing tube 1, thereby undergoing elastic deformation and fitting tightly to the inner wall of the splicing tube 1. Since rubber has good sealing performance and can deform with changes in external force, the first sealing ring 225 and the second sealing ring 226 can form an effective sealing barrier to prevent fluid or gas from leaking from the connection between the cone head tube 22 and the splicing tube 1.

[0038] Furthermore, the outer wall of the middle tube 21 has friction lines 211, which facilitate the staff to apply force during splicing.

[0039] Example 2

[0040] Different from Example 1, the side of the locking groove 222 close to the middle tube 21 has an elastic pad 224 for pressing the slider 11 against the inner wall of the locking groove 222, and the side of the locking groove 222 away from the elastic pad 224 has a locking protrusion 223, and the slider 11 is provided with a locking groove 111 corresponding to the locking protrusion 223.

[0041] When the slider 11 moves along the row groove 221 to the end of the row groove 221, it contacts the elastic pad 224 and continues to apply force to squeeze the elastic pad 224, thereby freeing up space for the slider 11 to move into the locking groove 222. After the slider 11 enters the locking groove 222 by rotating the splicing tube 1 or the connecting tube 2, the splicing action is stopped, so that the slider 11 is rebounded by the elastic pad 224, so that the clamping protrusion 223 is clamped in the clamping groove 111, further preventing the slider 11 from escaping from the locking groove 222, thereby ensuring the splicing. The connecting pipe 1 is locked on the connecting pipe 2. Through the action of the elastic pad 224, the slider 11 is tightly locked in the locking groove 222, which effectively prevents the connection from loosening or falling off due to external forces or vibrations, and significantly enhances the connection stability between the connecting pipe 2 and the splicing pipe 1. Through the cooperation of the latch 223 and the latch groove 111, the slider 11 is more firmly locked in the locking groove 222, which effectively prevents the connection from loosening or falling off due to external forces or vibrations, and significantly enhances the stability of the connection.

[0042] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
