Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline connection technology, and specifically to a pipeline connection device with leakage detection function. Background Technology
[0002] Pipelines are systems composed of pipes, fittings, valves, etc., mainly used to transport fluids (such as gases and liquids) and to deliver fluids according to process requirements and complete specific process flows in industrial production.
[0003] In existing technologies, pipelines are commonly used to transport large quantities of goods such as gases and liquids. They have advantages such as high efficiency, safety, and environmental friendliness. This method is suitable for long-distance, long-term transportation, such as the transportation of resources like natural gas, oil, and water. Compared with other modes of transportation, pipeline transportation does not generate problems such as noise, pollution, or traffic accidents, and therefore it is receiving increasing attention and application.
[0004] However, for example, when laying underground natural gas pipelines, when the pipeline travels too far, it is usually necessary to connect and install them before they can be used. Most of these connections are made by welding, which is time-consuming and labor-intensive. Furthermore, the sealing of the pipeline connections deteriorates due to prolonged use, making them prone to leaks. Workers may not be able to detect these leaks in time, and the pipeline remains in a leaking state, which can easily lead to accidents.
[0005] Based on this, this utility model designs a pipeline connection device with leakage detection function to solve the above problems. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a pipeline connection device with leakage detection function.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A pipeline connection device with leakage detection function includes a connecting ring, and also includes a pipeline leakage detection component, a pipeline connection component and a pipeline connection stabilization component;
[0009] The connecting ring is fixedly disposed on the outer surface of the connection between the two sets of pipes, and the connecting ring is provided in two sets symmetrically distributed;
[0010] A set of connecting rings is equipped with a pipeline leak detection component that can detect and alarm gas leaks inside the pipeline on its arc-shaped outer surface;
[0011] The outer surface of the connecting ring is equipped with a pipe connection assembly that can connect two sets of pipes;
[0012] The connecting ring is equipped with a pipe connection stabilizing component that can limit the position of the pipe connection assembly.
[0013] The pipe connection assembly and the pipe connection stabilizing assembly are connected and located at the connection point of the upper and lower sets of connecting rings. The pipe leakage detection assembly is located above the pipe connection assembly and the pipe connection stabilizing assembly.
[0014] The pipeline leak detection component includes an injection component and an alarm component. The injection component is connected to the alarm component and is located to the side of the alarm component. The injection component is connected to the inner side of the connecting ring.
[0015] Furthermore, the air injection assembly includes a pressure chamber, a piston, and a slider; the alarm assembly includes a vent pipe, a detection chamber, an alarm, and an airbag. The pressure chamber and the detection chamber are both fixedly mounted on the arc-shaped surface of the connecting ring. The pressure chamber is connected to the inner side of the connecting ring. The airbag is slidably mounted inside the detection chamber. The two ends of the vent pipe are fixedly connected to the pressure chamber and the airbag, respectively. The alarm is fixedly mounted on the outer surface of the detection chamber. The piston is slidably mounted on the inner wall of the pressure chamber, and the slider is fixedly mounted on the inner wall surface of the pressure chamber.
[0016] Furthermore, the piston has a groove on its arc-shaped surface, the slider is in contact with the groove and is slidably connected, and the diameter of the piston is larger than the diameter of the communication hole between the air chamber and the inner side of the connecting ring.
[0017] Furthermore, the pipe connection assembly includes a sector ring, a protrusion, a limiting block, and a positioning block. The sector ring is fixedly installed on the outer surface of the connecting ring plane, the limiting block is rotatably disposed on the outer surface of the connecting ring plane, the protrusion is fixedly disposed on the arc-shaped surface of the limiting block, and the positioning block is fixedly disposed on the outer surface of the connecting ring plane.
[0018] Furthermore, the sector ring, the limiting block, and the positioning block are concentric. The side of the limiting block that is in contact with the connecting ring has a positioning groove. The positioning block is in contact with the positioning groove and is rotatably connected. The inside of the sector ring has a through groove. The protrusion is in contact with the through groove and is slidably connected.
[0019] Furthermore, the pipe connection stabilizing component includes a spring and a baffle, the baffle being slidably disposed inside the connecting ring, and the spring being fixedly disposed on the bottom surface of the baffle.
[0020] Furthermore, a storage groove is provided on the outer surface of the connecting ring, the spring is located inside the storage groove, and a limit plate is fixed at the bottom of the baffle, so that the baffle cannot be removed from the storage groove.
[0021] Furthermore, the upper end of the baffle is in contact with the inner wall of the through groove, one side surface of the baffle is in contact with the side surface of the protrusion in a sliding connection, a fixing block is fixed on the outer surface of the pipe near the connection, an inner groove is opened on the inner surface of the connecting ring, a sealing strip is fixed on the inner surface of the connecting ring, the fixing block is in contact with the inner groove in a sliding connection, and the sealing strip is slidably engaged in the sealing groove opened on the outer surface of the pipe near the connection.
[0022] Compared with the prior art, the advantages of this utility model are as follows: 1. When it is necessary to connect two sets of pipes, two sets of connecting rings are sleeved on the outer surface of the connection between the two sets of pipes, and the fixing block is locked in the inner groove, and the sealing strip is locked in the sealing groove opened on the outer surface of the pipe, thereby initially connecting the two sets of pipes. Then, the baffle is pressed to store it in the storage groove. Then, the four sets of limiting blocks on both sides are rotated by the protrusion, so that the arc surface of each set of limiting blocks is simultaneously attached to the inner surface of the upper and lower sets of fan-shaped rings. Since the fan-shaped rings and the limiting blocks are concentric, and there are two sets of limiting blocks on each side, the upper and lower sets of connecting rings will be restricted by the limiting blocks and cannot be separated, thereby realizing the connection of the pipes. When the protrusion is pushed to the bottom, the baffle is stopped. Due to the elasticity of the spring, the spring reset will push the baffle out from the inside of the storage groove, so that the side surface of the baffle is attached to the side surface of the protrusion, thereby preventing the limiting block from rotating, thus realizing the stability of the pipe connection.
[0023] 2. When the pipeline is used for a long time, the sealing of the connection ports between the two sets of pipelines deteriorates, and the gas inside the pipeline will leak from the connection ports. Since there is a sealing strip between the connecting ring and the pipeline, the leaked gas will not enter the atmosphere, but will be retained in the inner groove of the connecting ring. This will increase the air pressure in the inner groove of the connecting ring. Since only the piston in the inner groove of the connecting ring is movable, the increased air pressure will push the piston upward, causing the piston to move upward. The movement of the piston will reduce the space inside the pressure chamber, thereby injecting the air inside the pressure chamber into the airbag through the vent pipe. The increase in air inside the airbag will cause its volume to increase. When the airbag increases slightly, it will contact the alarm installed inside the detection chamber, triggering the alarm and detecting the leak at the pipeline connection.

[0035] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0036] Example 1, please refer to the accompanying drawings in the specification. Figures 1-8 A pipeline connection device with leakage detection function includes a connecting ring 2, and also includes a pipeline leakage detection component 3, a pipeline connection component 4 and a pipeline connection stabilizing component 9;
[0037] The connecting ring 2 is fixedly installed on the outer surface of the connection between the two sets of pipes 1, and the connecting ring 2 is provided in two sets symmetrically distributed;
[0038] A set of connecting rings 2 has a pipeline leak detection component 3 installed on its arc-shaped outer surface, which can detect and alarm gas leaks inside the pipeline 1;
[0039] A pipe connection assembly 4, capable of connecting two sets of pipes 1, is installed on the outer surface of the connecting ring 2.
[0040] The connecting ring 2 is equipped with a pipe connection stabilizing component 9 that can limit the position of the pipe connection component 4;
[0041] Pipe connection component 4 and pipe connection stabilizing component 9 are connected. Pipe connection component 4 and pipe connection stabilizing component 9 are located at the connection of the upper and lower sets of connecting rings 2. Pipe leakage detection component 3 is located above pipe connection component 4 and pipe connection stabilizing component 9.
[0042] The pipeline leak detection component 3 includes an injection component and an alarm component. The injection component is connected to the alarm component and is located to the side of the alarm component. The injection component is connected to the inner side of the connecting ring 2.
[0043] Based on Embodiment 1, the air injection assembly includes a pressure chamber 15, a piston 19, and a slider 20. The alarm assembly includes a vent pipe 16, a detection chamber 17, an alarm 18, and an airbag 21. The pressure chamber 15 and the detection chamber 17 are both fixedly mounted on the arc-shaped surface of the connecting ring 2. The pressure chamber 15 is connected to the inner side of the connecting ring 2. The airbag 21 is slidably mounted inside the detection chamber 17. The two ends of the vent pipe 16 are fixedly connected to the pressure chamber 15 and the airbag 21, respectively. The alarm 18 is fixedly mounted on the outer surface of the detection chamber 17. The piston 19 is slidably mounted on the inner wall of the pressure chamber 15. The slider 20 is fixedly mounted on the inner wall surface of the pressure chamber 15.
[0044] The piston 19 has a groove 22 on its arc-shaped surface. The slider 20 is in contact with the groove 22 and is slidably connected. The diameter of the piston 19 is larger than the diameter of the communication hole between the air pressure chamber 15 and the inner side of the connecting ring 2.
[0045] The pipe connection assembly 4 includes a sector ring 5, a protrusion 6, a limiting block 7, and a positioning block 8. The sector ring 5 is fixedly installed on the outer surface of the plane of the connecting ring 2. The limiting block 7 is rotatably disposed on the outer surface of the plane of the connecting ring 2. The protrusion 6 is fixedly disposed on the arc-shaped surface of the limiting block 7. The positioning block 8 is fixedly disposed on the outer surface of the plane of the connecting ring 2.
[0046] The sector ring 5, the limiting block 7 and the positioning block 8 are concentric. The side of the limiting block 7 that is in contact with the connecting ring 2 is provided with a positioning groove 10. The positioning block 8 is in contact with the positioning groove 10 and is rotatably connected. The inside of the sector ring 5 is provided with a through groove 11. The protrusion 6 is in contact with the through groove 11 and is slidably connected.
[0047] The pipe connection stabilizing component 9 includes a spring 13 and a baffle 14. The baffle 14 is slidably disposed inside the connecting ring 2, and the spring 13 is fixedly disposed on the bottom surface of the baffle 14.
[0048] A storage groove 12 is provided on the outer surface of the connecting ring 2. The spring 13 is located inside the storage groove 12. A limit plate is fixed at the bottom of the baffle 14, and the baffle 14 cannot be removed from the storage groove 12.
[0049] The upper end of the baffle 14 is attached to the inner wall of the through groove 11. One side surface of the baffle 14 is attached to the side surface of the protrusion 6 in a sliding connection. A fixing block 23 is fixed on the outer surface of the pipe 1 near the connection. An inner groove 25 is opened on the inner surface of the connecting ring 2. A sealing strip 24 is fixed on the inner surface of the connecting ring 2. The fixing block 23 is attached to the inner groove 25 in a sliding connection. The sealing strip 24 is slidably locked in the sealing groove opened on the outer surface of the pipe 1 near the connection.
[0050] In actual use, when it is necessary to connect two sets of pipes 1, the two sets of connecting rings 2 are fitted onto the outer surface of the connection between the two sets of pipes 1, while the fixing block 23 is locked in the inner groove 25, and the sealing strip 24 is locked in the sealing groove opened on the outer surface of the pipe 1, thus initially connecting the two sets of pipes 1. Then, the baffle 14 is pressed to store it into the storage groove 12. Then, the four sets of limiting blocks 7 on both sides are rotated by the protrusion 6, so that the arc-shaped surface of each set of limiting blocks 7 simultaneously contacts the inner surface of the upper and lower sets of fan-shaped rings 5. When the surfaces are in contact, since the sector ring 5 and the limiting block 7 are concentric and there are two sets of limiting blocks 7 on each side, the upper and lower connecting rings 2 will be restricted by the limiting blocks 7 and cannot be separated, thus realizing the connection of the pipe. When the protrusion 6 is pushed to the bottom, stop pressing the baffle 14. Due to the elasticity of the spring 13, the spring 13 will return to its original position and push the baffle 14 out from the inside of the receiving groove 12, so that the side surface of the baffle 14 is in contact with the side surface of the protrusion 6, thus preventing the limiting block 7 from rotating, thereby realizing the stability of the pipe connection.
[0051] When pipe 1 is used for a long time, the sealing of the connection port between the two sets of pipes 1 decreases, and the gas inside pipe 1 will leak from the connection port. Since there is a sealing strip 24 between the connecting ring 2 and pipe 1, the leaked gas will not enter the atmosphere, but will be stored in the inner groove of the connecting ring 2, which will increase the air pressure in the inner groove of the connecting ring 2. Since only piston 19 is movable in the inner groove of the connecting ring 2, the increased air pressure will push piston 19, causing piston 19 to move upward. The movement of piston 19 will reduce the space inside the air pressure chamber 15, thereby injecting the air inside the air pressure chamber 15 into the airbag 21 through the vent pipe 16. The increase in air inside the airbag 21 will cause its volume to increase. When the airbag 21 increases slightly, it will contact the alarm 18 installed inside the detection chamber 17, causing the alarm 18 to work and detect the leakage problem at the connection of pipe 1.
[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended 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. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
