Description

Technical Field

[0001] This utility model relates to the field of building decoration and installation of external gas pipelines in residential buildings, specifically a safe gas pipeline for residential use. Background Technology

[0002] Gas pipes are specialized pipelines for gas use, characterized by easy installation, reliable connections, corrosion resistance, non-clogging properties, and long service life. Gas pipelines are now required around residential buildings, making them an indispensable facility in living areas. Underground installation effectively isolates the pipeline from physical contact with the ground environment, preventing damage caused by human error or traffic accidents. The soil layer acts as a natural barrier, significantly reducing the probability of explosions caused by gas leaks, making it particularly suitable for installation in densely populated areas. The constant moisture and pressure environment of the soil slows down the corrosion rate of the pipeline metal, and combined with cathodic protection technology, can extend its service life by 15-20 years. Furthermore, underground installation reduces the degradation effect of ultraviolet radiation on the pipe material, lowering the frequency of maintenance.

[0003] Traditional gas pipeline installations are not secure enough, are inconvenient to lay, and have poor sealing at the contact points with the ground, reducing the service life of the gas pipelines. At the same time, the above-ground gas pipeline sections are prone to collisions with external objects due to the lack of protective devices, posing safety hazards. Therefore, the installation safety and stability of existing underground gas pipelines outside residential buildings are poor and do not meet the existing installation specifications and technical requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a residential safety gas pipeline with a more reasonable structural design, easy processing, low processing and manufacturing cost, convenient installation and disassembly, and a specially designed protective pipe at the contact position between the gas pipeline and the ground. This improves the safety performance of the installation and provides a protective device for the gas pipeline on the ground, which can effectively prevent the gas pipeline located on the ground from being collided with and causing safety hazards.

[0005] This utility model discloses a residential safety gas pipeline, comprising a gas pipeline including a vertical pipe, a connecting elbow, and a horizontal pipe. The vertical pipe is installed through the ground, with its upper half above ground and its lower half below ground. The bottom end of the vertical pipe is fixedly connected to one end of the connecting elbow, and the other end of the connecting elbow is fixedly connected to the horizontal pipe. A steel-plastic conversion joint is fixedly connected to the end of the horizontal pipe, and the steel-plastic conversion joint is fixedly connected to the gas PE pipeline. A protective sleeve is fitted on the outer wall of the vertical pipe.

[0006] The gas pipeline system includes risers, connecting elbows, and horizontal pipes. The upper part of the riser is installed above ground, and the lower part is installed below ground, allowing for better connection to underground natural gas pipelines. The top of the riser, located externally, can also connect to overhead pipelines outside residential buildings, thus providing convenient gas access for residents after connecting the underground natural gas pipelines. Connecting elbows connect the risers and horizontal pipes, effectively converting the upward-extending risers into horizontal pipes, facilitating connection to underground natural gas pipelines. The risers, connecting elbows, and horizontal pipes are made of steel pipes, possessing high strength and durability, capable of withstanding significant internal and external pressures, suitable for high-pressure gas transmission, with a long service life, relatively low maintenance costs, and suitability for long-term use. They can be recycled after disposal, meeting environmental protection requirements and reducing costs. The investment enhances the economic efficiency of its use. The steel-plastic conversion joint allows for better connection between horizontal pipes and gas PE pipes, achieving a superior connection between the two different materials. The tight connection and strong sealing ensure the airtightness of the gas pipeline, improving installation safety. The gas PE pipe ends are fixedly connected to the buried PE pipes, allowing natural gas from the buried PE pipes to pass through the gas PE pipes and the gas pipeline, completing the closed-loop transmission of natural gas. Burying the gas PE pipes underground provides excellent adaptability to uneven settlement of the pipe foundation, excellent seismic performance, and adaptability to various geological conditions. Its corrosion resistance reduces maintenance frequency and costs. It is also less prone to puncture by hard objects, reducing the risk of gas leakage. The low material, construction, and maintenance costs make it economical and environmentally friendly.

[0007] The protective sleeve is fixedly installed through the ground.

[0008] The upper surface and lower bottom surface of the protective sleeve are respectively fixedly connected with elastic plugs, and the elastic plugs are sleeved on the outer wall surface of the vertical pipe.

[0009] The protective sleeve is installed on the outer wall of the riser, located at the contact point between the riser and the ground. This provides better protection for the riser, which is a relatively weak point in the installation. Strengthening the riser's burial strength improves the safety and reliability of the installation, extends its service life, and ensures high strength. The protective sleeve is fixedly connected to the riser, providing highly reliable waterproof sealing and strong high-temperature resistance. The internal fixing method completely eliminates the need for external concrete supports, saving costs and shortening the construction period. It ensures the entire pipeline operates in a fully sealed environment, ensuring safety and reliability and extending the overall service life of the pipeline.

[0010] The elastic plugs are fixedly connected to the upper and lower surfaces of the protective sleeve. Their main function is to prevent gas leakage and protect the structural performance of the interface between the vertical pipe and the protective sleeve. They can improve the structural performance of the interface between two adjacent gas pipelines that are welded together, preventing corrosion of the welded interface between the protective sleeve and the vertical pipe under special climatic conditions, extending its service life, and providing flame retardant properties. They can also give the welded interface between the protective sleeve and the vertical pipe excellent water repellency, waterproofing, antifreeze, and anti-icing properties.

[0011] A protective railing is installed on the side of the vertical pipe.

[0012] The guardrail includes a fixed vertical bar, a first fixing plate fixedly connected to the bottom end of the fixed vertical bar, a fixed horizontal bar fixedly connected to the side wall of the fixed vertical bar, and a second fixing plate fixedly connected to the end of the fixed horizontal bar.

[0013] The surfaces of the first fixing plate and the second fixing plate are provided with mounting holes.

[0014] The protective railing is fixedly installed on one side of the vertical pipe, effectively preventing unauthorized personnel from damaging or accidentally touching the pipeline, reducing the occurrence of safety accidents. Made of steel pipe, it is corrosion-resistant and high-strength. The gas pipeline protective railing also serves as a marker, reminding people to pay attention to pipeline safety and enhancing the aesthetics of the city or community. The first and second fixing plates can be bolted through the mounting holes on their surfaces to fix the vertical rod to the ground and the horizontal rod to the wall surface, ensuring stable installation, convenient disassembly and maintenance, and more flexible operation.

[0015] The number of fixed crossbars is two, one of which is fixedly connected to the top of the fixed vertical bar, and the other is fixedly connected to the middle of the fixed vertical bar.

[0016] The beneficial effects of this utility model are: 1) The gas pipeline consists of risers, connecting elbows, and horizontal pipes. The upper part of the riser is installed above ground, and the lower part is installed below ground, allowing for better connection to underground natural gas pipelines. The top of the riser, located externally, can also connect to overhead pipelines outside residential buildings, thus facilitating convenient gas supply for residents after connecting the underground natural gas pipelines. Connecting elbows connect the risers and horizontal pipes, effectively converting the upward-extending risers into horizontal pipes, further facilitating connection to underground natural gas pipelines. The risers, connecting elbows, and horizontal pipes are made of steel pipes, possessing high strength and durability, capable of withstanding significant internal and external pressures, suitable for high-pressure gas transmission, with a long service life, relatively low maintenance costs, and suitable for long-term use. After disposal, they can be recycled and reused, meeting environmental protection requirements and reducing costs. This investment improves the economic efficiency of use; the installed steel-plastic conversion joint can better connect horizontal pipes and gas PE pipes, achieving a better connection between two different materials. The connection is tight and has strong sealing performance, fully ensuring the sealing of the gas pipeline and improving installation safety; the end of the gas PE pipe is fixedly connected to the buried PE pipe, allowing natural gas in the buried PE pipe to pass through the gas PE pipe and the gas pipeline, completing the closed-loop transmission of natural gas; burying the gas PE pipe underground makes it highly adaptable to uneven settlement of the pipe foundation, with excellent seismic performance, adaptable to various geological conditions, and corrosion-resistant, reducing the frequency and cost of maintenance. It is not easily punctured by hard objects, thus reducing the risk of gas leakage. The material cost, construction cost, and maintenance cost are low, making it economical and environmentally friendly.

[0017] 2) The protective sleeve is installed on the outer wall of the vertical pipe, located at the contact point between the vertical pipe and the ground. This provides better protection for the vertical pipe, which is a relatively weak point in the installation. This sleeve strengthens the buried strength of the vertical pipe, improves the safety and reliability of the installation, and extends the service life of the vertical pipe. It has high strength, and the protective sleeve is fixedly connected to the vertical pipe, ensuring high reliability of waterproof sealing performance and strong high temperature resistance. The internal fixing method completely eliminates the need for external fixed concrete supports, saving costs and shortening the construction period. It ensures that the entire working pipeline operates in a fully sealed environment, ensuring safety and reliability and extending the service life of the entire working pipeline.

[0018] 3) The elastic plugs are fixedly connected to the upper and lower surfaces of the protective sleeve. Their main function is to prevent gas leakage and protect the structural performance of the interface between the vertical pipe and the protective sleeve. They can improve the structural performance of the interface between two adjacent gas pipelines that are welded together, preventing corrosion of the welded interface between the protective sleeve and the vertical pipe under special climatic conditions, extending its service life, and providing flame retardant properties. They can also give the welded interface between the protective sleeve and the vertical pipe excellent water repellency, waterproofing, antifreeze, and anti-icing properties.

It is made of steel pipe, which has the characteristics of corrosion resistance and high strength. The gas pipeline protective railing also has a certain identification function, reminding people to pay attention to pipeline safety and enhancing the aesthetics of the city or community. The first and second fixing plates can be fixed to the ground and the horizontal bar to the wall surface by bolts through the mounting holes on the surface of the first and second fixing plates. The installation is stable, disassembly and maintenance are convenient, and the operation is more flexible.

[0020] 5) The structure is more reasonable, easier to process, has low processing and manufacturing costs, is easy to install and disassemble, and has a special protective pipe at the contact point between the gas pipeline and the ground for safe installation of outdoor gas pipelines, which improves the safety performance of the installation. The protective device on the ground part of the gas pipeline can effectively prevent the gas pipeline located above ground from being collided and causing safety hazards. This pipeline has been put into use in the renovation project of gas pipeline supporting facilities for residential users and is worth promoting and applying on a large scale.
