Water pipeline connecting piece

Abstract

This utility model discloses a water conservancy pipeline connector, including an outer pipe and a sealing pipe, with the sealing pipe sleeved at the end of the outer pipe. Several spring pieces are connected to the end of the outer pipe, and the inner wall of the outer pipe has internal threads. The connector also includes an inner pipe, the outer wall of which has external threads that are screwed into the internal threads. The end of the inner pipe has a flared opening that expands the spring pieces. The spring pieces are bent to form a flared shape, thus expanding the sealing pipe onto the inner wall of the water conservancy pipeline. By relatively rotating the outer and inner pipes, the flared opening of the inner pipe moves towards the center of the spring pieces. Due to the larger outer diameter of the flared opening, the spring pieces are lifted and expanded. Supported by the flared opening, the spring pieces form a flared shape, with the outer diameter of the spring pieces being larger than the outer diameter of the flared opening. The sealing pipe, sleeved at the end of the outer pipe, has elastic rubber support, allowing it to expand with the spring pieces and sealingly connect to the inner wall of the water conservancy pipeline and the outer pipe.

Description

Technical Field

[0001] This utility model relates to a water conservancy pipeline connector, and more particularly to its tightening mechanism, belonging to the field of water conservancy engineering technology. Background Technology

[0002] Hydraulic pipelines are devices used to transport liquids or gases, connected by pipes, pipe fittings, and valves. Typically, fluids are pressurized by pumps and flow from high-pressure areas to low-pressure areas in the pipeline, or they can be transported using their own pressure or gravity. Hydraulic pipelines are an important component of water conservancy projects, serving as crucial channels for controlling water flow, preventing floods, and regulating and distributing water volume. Often, several pipelines need to be connected together to transport water to suitable locations. Currently, pipelines are connected via flanges. Flanges are connected to pipes by welding or clamps. Adjacent flanges are connected by bolts or screws. This connection method requires perfect alignment of adjacent pipes and appropriate distance between pipe ends; otherwise, gaps and leaks will occur. Furthermore, disassembly and assembly are inconvenient, time-consuming, and labor-intensive. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a water conservancy pipeline connector, comprising an outer pipe and a sealing pipe, wherein the sealing pipe is sleeved on the end of the outer pipe; the end of the outer pipe is connected with a plurality of spring pieces, and the inner wall of the outer pipe is provided with an internal thread; the water conservancy pipeline connector also includes an inner pipe, the outer wall of the inner pipe is provided with an external thread, the external thread is screwed into the internal thread, and the end of the inner pipe is provided with a flared mouth, the flared mouth expands the spring pieces, and the plurality of spring pieces are bent to form a flared shape, thereby expanding the sealing pipe onto the inner wall of the water conservancy pipeline.

[0005] The present invention is further configured such that: the water conservancy pipeline is a flexible hose, including a first pipeline and a second pipeline, the end of the second pipeline being inserted into the end of the first pipeline; and the sealing tube being expanded and connected to the inner wall of the second pipeline.

[0006] The present invention is further configured such that: both ends of the inner tube are provided with flared openings; there are two outer tubes and two sealing tubes; the water conservancy pipeline includes a first pipeline and a second pipeline, and the pair of sealing tubes are respectively expanded and connected to the inner walls of the first pipeline and the second pipeline.

[0007] A further feature of this invention is that there is a slit between the adjacent spring pieces.

[0008] The present invention is further configured such that the spring sheet is a double layer, including a plurality of outer spring sheets and a plurality of inner spring sheets, the outer spring sheets are superimposed on the inner spring sheets and cover the slits between the inner spring sheets.

[0009] A further feature of this invention is that the outer wall of the outer tube is provided with several anti-slip protrusions.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: By relatively rotating the outer and inner tubes, the flared opening of the inner tube moves towards the center of several spring pieces. Due to the large outer diameter of the flared opening, the spring pieces are lifted and expanded.

[0018] See appendix Figure 1-6As shown, a water conservancy pipeline connector in this embodiment includes an outer pipe 4 and a sealing pipe 5, with the sealing pipe 5 sleeved on the end of the outer pipe 4; the end of the outer pipe 4 is connected to a plurality of spring pieces 7, and the inner wall of the outer pipe 4 is provided with an internal thread; the water conservancy pipeline connector also includes an inner pipe 3, the outer wall of the inner pipe 3 is provided with an external thread 9, the external thread 9 is screwed to the internal thread, the end of the inner pipe 3 is provided with a flared mouth 6, the flared mouth 6 expands the spring pieces 7, and the plurality of spring pieces 7 are bent to form a flared shape, thereby expanding the sealing pipe 5 onto the inner wall of the water conservancy pipeline.

[0019] By rotating the outer tube 4 and the inner tube 3 relative to each other, the flared opening 6 of the inner tube 3 moves towards the center of several spring pieces 7. Because the outer diameter of the flared opening 6 is relatively large, it pushes up and expands the spring pieces 7. Supported by the flared opening 6, the spring pieces 7 form a flared shape, with the outer diameter of the spring pieces 7 being larger than the outer diameter of the flared opening 6. The sealing tube 5, fitted onto the end of the outer tube 4, is made of elastic rubber and can expand with the spring pieces 7, sealingly connecting the inner wall of the water pipe to the outer tube 4.

[0020] The present invention is further configured such that: the water conservancy pipeline is a flexible hose, including a first pipeline 1 and a second pipeline 2, with the end of the second pipeline 2 inserted into the end of the first pipeline 1; the sealing tube 5 is expanded and connected to the inner wall of the second pipeline 2. With the first pipeline 1 and the second pipeline 2 separated, the outer wall of the outer tube 4 and the inner tube 3 are held by both hands and rotated relative to each other, causing the flared end 6 to enter the center of the spring piece 7. The spring piece 7 and the sealing tube 5 expand the second pipeline 2 tightly against the inner wall of the first pipeline 1. Water flows from the first pipeline 1 through the inner tube 3 into the second pipeline 2.

[0021] If the first pipe 1 and the second pipe 2 are made of rigid steel pipes, and are some distance apart, they are difficult to connect. Therefore, this invention further specifies that: both ends of the inner pipe 3 are provided with flared openings 6; there are two outer pipes 4 and two sealing pipes 5; the water conservancy pipeline includes the first pipe 1 and the second pipe 2, and the pair of sealing pipes 5 are respectively expanded onto the inner walls of the first pipe 1 and the second pipe 2. The length of the inner pipe 3 is slightly greater than the distance between the ends of the first pipe 1 and the second pipe 2, and both ends of the inner pipe 3 are inserted into the ends of the first pipe 1 and the second pipe 2. Without needing to separate the first pipe 1 and the second pipe 2, both hands directly grasp the outer walls of the outer pipe 4 and the inner pipe 3, rotating them relative to each other, causing the flared openings 6 to enter the center of the spring clips 7. The spring clips 7 and the sealing pipes 5 on the two outer pipes 4 are then expanded tightly onto the inner walls of the first pipe 1 and the second pipe 2. Water flows from the first pipe 1 through the inner pipe 3 into the second pipe 2.

[0022] A further feature of this invention is that a slit 8 is provided between the adjacent spring pieces 7.

[0023] To enhance the elasticity of the sealing tube 5 by fully supporting the spring piece 7, this invention further comprises: the spring piece 7 having two layers, including several outer spring pieces 7 and several inner spring pieces 7, with the outer spring pieces 7 stacked on top of the inner spring pieces 7 and covering the slits 8 between the inner spring pieces 7. When the flared opening 6 extends into the center of the spring piece 7, the inner and outer spring pieces 7 simultaneously rise and expand. Supported by the flared opening 6, a flared shape without gaps is formed, fully supporting the increased elasticity of the sealing tube 5.

[0024] To facilitate gripping, the present invention is further provided with a plurality of anti-slip protrusions 10 on the outer wall of the outer tube 4.

[0025] In summary, the principle of the hydraulic pipeline connector shown in this utility model is as follows: Through the threaded connection between the outer pipe 4 and the inner pipe 3, relative rotational movement causes the flared end 6 to enter the center of the spring piece 7. The flared end 6 acts as a fulcrum, lifting and expanding the spring piece 7. Several spring pieces 7 form a flared shape, with the outer diameter of the spring piece 7 being larger than the outer diameter of the flared end 6. The sealing tube 5, sleeved at the end of the outer pipe 4, is made of elastic rubber and can expand with the spring piece 7, sealingly connecting the inner wall of the hydraulic pipeline to the outer pipe 4. Adjacent hydraulic pipelines are connected. Water flows out through the inner pipe 3 to the adjacent hydraulic pipeline. When it is necessary to disassemble the adjacent pipeline, the inner pipe 3 and the outer pipe 4 are rotated in the opposite direction, causing the flared end 6 to move outward from the center of the spring piece 7, and the spring piece 7 returns to its original shape. The sealing tube 5 contracts and detaches from the inner wall of the hydraulic pipeline. At this point, the hydraulic pipeline connector shown in this patent application can be removed from the hydraulic pipeline, and the adjacent hydraulic pipeline can be cut off.
