Description

Technical Field

[0001] This utility model belongs to the field of pipeline safety technology, specifically an explosion-proof and leak-proof safety device for natural gas pipelines. Background Technology

[0002] Natural gas, as a clean and efficient energy source, occupies a crucial position in the modern energy supply system. It is transported through a complex pipeline network, continuously delivering natural gas from production or storage sites to various end users. Natural gas pipelines face numerous safety risks during operation, especially explosions and leaks. These not only directly threaten the lives of people near the pipelines but can also cause fires, environmental pollution, and a series of other serious consequences, resulting in enormous losses to the socio-economic and ecological environment. To prevent explosions and leaks, existing natural gas pipelines install sealing rings at the connection points between two pipelines. The sealing rings are deformed by the pressure of the two pipelines, thus achieving a seal at the connection point. However, these sealing rings are prone to aging after prolonged use and require periodic disassembly and replacement. Since the sealing rings are installed between two pipelines, disassembly and replacement are inconvenient; therefore, improvements are needed. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an explosion-proof and leak-proof safety device for natural gas pipelines. It solves the problem that existing natural gas pipelines install sealing rings at the connection points of two pipelines to prevent explosions and leaks. The sealing rings are deformed by the compression of the two pipelines to achieve sealing at the pipeline connection points. However, the sealing rings are prone to aging after long-term use and need to be disassembled and replaced regularly. Since the sealing rings are installed between the two pipelines, it is inconvenient to disassemble and replace them.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof and leak-proof safety device for a natural gas pipeline, comprising a sealing cover one, with mounting brackets fixedly installed at both ends of the outer surface of the sealing cover one, symmetrically provided with receiving grooves on both sides of the mounting brackets, and fixed studs symmetrically rotatably installed inside the receiving grooves via pins, with a fixed nut threadedly connected to the threaded surface of the top of the fixed studs; a sealing cover two is provided on the top of the sealing cover one, with connecting brackets fixedly installed at both ends of the outer surface of the sealing cover two, and the positions of the connecting brackets and the mounting brackets corresponding to each other; symmetrically provided with connecting slots on both sides of the connecting brackets, and the fixed studs rotatably engaging inside the connecting slots; mounting grooves are provided on opposite sides of the sealing cover one and the sealing cover two, with connecting disc one and connecting disc two provided inside the two mounting grooves; and a pipeline body is fixedly installed on the opposite sides of the connecting disc one and the connecting disc two.

[0005] As a further embodiment of this utility model: positioning blocks are symmetrically fixedly installed on both sides of the inner wall of the mounting groove, and an arc-shaped sealing gasket is fixedly installed at the center of the arc-shaped inner wall of the mounting groove, and the arc-shaped sealing gasket is tightly attached to the joint between the first connecting plate and the second connecting plate.

[0006] As a further embodiment of this utility model: an annular sealing gasket is provided between the first connecting plate and the second connecting plate, and the surface of the annular sealing gasket is provided with symmetrical positioning through holes.

[0007] As a further embodiment of this utility model: the first connecting plate is provided with symmetrical positioning holes on the side away from the main body of the pipe, and the second connecting plate is provided with symmetrical positioning blocks on the side away from the main body of the pipe, and the positions of the positioning blocks correspond to the positioning through holes and the positioning holes.

[0008] As a further embodiment of this utility model: the connecting plate one and the connecting plate two are respectively provided with multiple positioning slots on the side near the pipe body, and the positioning slots correspond to the positions of the positioning blocks.

[0009] As a further embodiment of this utility model: a plurality of connecting bolts are provided through one side of the connecting disc, and the connecting bolts pass through the annular sealing gasket and the connecting disc.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The explosion-proof and leak-proof safety device for the natural gas pipeline includes a sealing cover I, a sealing cover II, a fixing stud, a fixing nut, and a connecting frame. After connecting plate I and connecting plate II are combined and connected, the sealing cover I and sealing cover II are moved and suspended relative to each other at the connection position of connecting plate I and connecting plate II. The sealing cover I and sealing cover II are moved tightly to cover the connection position of connecting plate I and connecting plate II. The fixing stud is rotated and inserted into the corresponding two sides of the connecting frame. The fixing nut is tightened to fix the fixing stud on both sides of the connecting frame, thus fixing the sealing cover I and sealing cover II together and sealing the connection between connecting plate I and connecting plate II. This prevents natural gas from leaking from the connection position of connecting plate I and connecting plate II when it flows in the pipeline, and facilitates the disassembly and replacement of sealing cover I and sealing cover II. 2. The explosion-proof and leak-proof safety device for this natural gas pipeline consists of a positioning block, a connecting plate 1, a connecting plate 2, an annular sealing gasket, a positioning insert, and a positioning slot. The annular sealing gasket is suspended between connecting plate 1 and connecting plate 2, aligning the positioning through hole, positioning insert, and positioning insert. Connecting plate 1 and connecting plate 2 are moved to fit tightly against both sides of the annular sealing gasket, allowing the positioning insert to pass through the positioning through hole and insert into the corresponding positioning insert. The connecting bolts are then tightened to connect connecting plate 1, the annular sealing gasket, and connecting plate 2, ensuring that there is no misalignment during connection. Finally, sealing cover 1 and sealing cover 2 are wrapped around the surfaces of connecting plate 1 and connecting plate 2, allowing the positioning block to insert into the corresponding positioning slot, ensuring that sealing cover 1 and sealing cover 2 are secured to the surfaces of connecting plate 1 and connecting plate 2 without misalignment or deflection.

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-3 As shown, this utility model provides a technical solution: an explosion-proof and leak-proof safety device for natural gas pipelines, including a sealing cover 1. The two ends of the outer surface of the sealing cover 1 are respectively fixedly installed with mounting brackets 2. The mounting brackets 2 are symmetrically provided with storage grooves 3 on both sides. The storage grooves 3 are symmetrically installed with fixing studs 4 through pins. Because there are storage grooves 3, the fixing studs 4 are rotated and inserted into the storage grooves 3. The fixing nuts 5 are tightened to fit tightly against the mounting brackets 2, thereby fixing the fixing studs 4 in the storage grooves 3, ensuring that the fixing studs 4 will not sway freely on both sides of the mounting brackets 2. The threaded surface of the top of the fixing stud 4 is threaded and connected to the fixing nut 5. The top of the sealing cover 1 is provided with the sealing cover 2 6. The two ends of the outer surface of the sealing cover 2 6 are respectively fixedly installed with the connecting bracket 7, and the connecting bracket 7 is corresponding to the position of the mounting bracket 2. The connecting bracket 7 is symmetrically provided with the connecting slots 8 on both sides, and the fixing stud 4 is rotated and engaged in the connecting slots 8. By providing the connecting bracket 7, after the sealing cover 1 and the sealing cover 2 6 are pressed together, the fixing stud 4 is rotated and engaged in the connecting slots 8 on both sides of the connecting bracket 7. The fixing nut 5 is tightened to fix the fixing stud 4 in the connecting slots 8, thereby connecting and fixing the sealing cover 1 and the sealing cover 2 6, so that the sealing cover 1 and the sealing cover 2 6 are wrapped and fixed on the surface of the connecting plate 11 and the connecting plate 2 12. The sealing cover 1 and sealing cover 2 are respectively provided with mounting grooves 9 on opposite sides. Connecting disc 11 and connecting disc 2 12 are located inside the two mounting grooves 9. Pipe bodies 13 are fixedly installed on the opposite sides of connecting discs 11 and 2 12. Positioning blocks 10 are symmetrically fixedly installed on both sides of the inner wall of the mounting groove 9. An arc-shaped sealing gasket 20 is fixedly installed at the center of the arc-shaped inner wall of the mounting groove 9, and the arc-shaped sealing gasket 20 is tightly fitted to the joint of connecting discs 11 and 2 12. Because of the arc-shaped sealing gasket 20, after sealing cover 1 and sealing cover 2 6 are placed on the surfaces of connecting discs 11 and 2 12, the arc-shaped sealing gasket 20 is tightly fitted to the joint of connecting discs 11 and 2 12, thereby sealing the joint of connecting discs 11 and 2 12 and preventing leakage of hot air from the joint of connecting discs 11 and 2 12.

[0014] An annular sealing gasket 14 is provided between connecting disc 11 and connecting disc 2 12, and symmetrical positioning through holes 15 are provided through the surface of the annular sealing gasket 14. A positioning insertion hole 16 is symmetrically provided on the side of connecting disc 11 away from the pipe body 13, and a positioning insertion block 17 is symmetrically fixedly installed on the side of connecting disc 2 12 away from the pipe body 13. The positioning insertion block 17 corresponds to the positioning through hole 15 and the positioning insertion hole 16. By providing the positioning insertion block 17, when the annular sealing gasket 14 is placed between connecting disc 11 and connecting disc 2 12, the positioning through hole 15, the positioning insertion hole 16 and the positioning insertion block 17 are aligned. When connecting disc 11 and connecting disc 2 12 are moved closer to both sides of the annular sealing gasket 14, the positioning insertion block 17 passes through the positioning through hole 15 and is inserted into the corresponding positioning insertion hole 16. This ensures that there will be no misalignment or deflection when connecting disc 11, connecting disc 2 12 and annular sealing gasket 14 are connected.

[0015] Multiple positioning slots 18 are provided on the side of connecting plate 11 and connecting plate 2 near the main body of pipe 13, and the positioning slots 18 correspond to the positions of positioning blocks 10. Because of the positioning slots 18, when sealing cover 1 and sealing cover 2 6 are put on the surface of connecting plate 11 and connecting plate 2 12, the positioning blocks 10 are inserted into the corresponding positioning slots 18, ensuring that sealing cover 1 and sealing cover 2 6 will not be misaligned or deflected on the surface of connecting plate 11 and connecting plate 2 12.

[0016] Multiple connecting bolts 19 are provided through one side of the connecting disc 2 12, and the connecting bolts 19 pass through the annular sealing gasket 14 and the connecting disc 11. Because of the connecting bolts 19, after the connecting disc 11 and the connecting disc 2 12 are attached to the two sides of the annular sealing gasket 14 respectively, the connecting bolts 19 are tightened to pass through the connecting disc 11, the annular sealing gasket 14 and the connecting disc 2 12, thereby combining and connecting the connecting disc 11, the connecting disc 2 12 and the annular sealing gasket 14.

[0017] The working principle of this utility model is as follows: Suspend connecting disc 11 and connecting disc 22 opposite each other on both sides of the annular sealing gasket 14. Move connecting disc 11 and connecting disc 22 closer to both sides of the annular sealing gasket 14 so that the positioning insert 17 passes through the positioning through hole 15 and is inserted into the positioning insert 16. Ensure that connecting disc 11 and connecting disc 22 will not be misaligned when they are combined and connected on both sides of the annular sealing gasket 14. Tighten the connecting bolt 19 through connecting disc 11 and connecting disc 22 to fix connecting disc 11 and connecting disc 22 on both sides of the annular sealing gasket 14. Move sealing cover 11 to align with the joint of connecting disc 11 and connecting disc 22, and snap sealing cover 11 into the connecting disc 11. At the bottom of the joint between 11 and 12, the positioning block 10 is inserted into the corresponding positioning slot 18. Then, the sealing cover 2 6 is moved to align with the sealing cover 1 and cover the joint between 11 and 12. The fixing stud 4 is rotated and inserted into the connecting slot 8. The fixing nut 5 is tightened to secure the fixing stud 4 in the connecting slot 8, thereby fixing the sealing cover 1 and the sealing cover 2 6 to the joint surface of 11 and 12, sealing the joint between 11 and 12, and preventing natural gas from leaking from the joint between 11 and 12 when it flows inside the pipeline body 13.
