Description

Technical Field

[0001] This utility model relates to the field of natural gas pipeline technology, and in particular to a safety sewage discharge device for a natural gas pipeline ball valve. Background Technology

[0002] During natural gas transportation, it carries solid impurities such as sand, rust, and welding slag. These impurities gradually accumulate inside ball valves as they flow through the pipeline, affecting their normal opening and closing. Safety drainage devices can periodically or continuously remove these impurities from the pipeline system. However, they cannot effectively remove magnetic materials (such as iron filings) from natural gas, nor can they effectively remove both larger and smaller solid particles. For example, Chinese patent disclosure "Safety Drainage Tool for Ball Valves Below DN100 in Natural Gas Pipelines" (application number "2019222441") provides an example. The 63.5” device allows for easy and quick docking through an acrylic transparent viewing window during the docking process via the positioning frame, facilitating accurate and rapid connection and enhancing usability. Simultaneously, it clears blockages from the ball valve drain nozzle by passing the inner pipe through the drain pipe of the ball valve and the main vent pipe, ensuring unobstructed flow. However, it lacks multi-stage impurity treatment capabilities, offering only basic unblocking functionality. It cannot effectively remove magnetic materials (such as iron filings) from natural gas, nor can it effectively separate larger solid particles from smaller particulate impurities. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a safe sewage discharge device for a natural gas pipeline ball valve. During sewage discharge, the valve closes the downstream pipeline. At this time, the sewage natural gas and impurities will enter the processing shell through the sewage pipe. Under the flow of natural gas, the fan blades will rotate, and the fan blades will drive the rotating shaft to rotate the arc-shaped push plate. The arc-shaped push plate will push the larger impurities in the natural gas to the surrounding areas. Magnetic substances in the impurities will be attracted by the surrounding magnetic sheets, which can ensure that magnetic substances (such as iron filings) can be effectively removed. The remaining impurities will eventually fall into the storage jacket. The remaining natural gas will enter the return pipe and be screened by three screens before entering the downstream pipeline. This multi-stage processing method can more comprehensively remove impurities in natural gas, effectively remove larger solid particles and magnetic substances, and further filter out smaller particulate impurities through the screens, thereby significantly improving the purity and quality of natural gas.

Detailed Implementation

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 This utility model provides a safety sewage discharge device for a natural gas pipeline ball valve, comprising: a ball valve body 1, a pad 26 fixedly connected to the rear surface of the ball valve body 1, an mounting plate 27 fixedly connected to the rear surface of the pad 26, a connecting pipe 4 connected to one end of the ball valve body 1, a valve 5 connected to one end of the connecting pipe 4, a downstream pipe 6 connected to one end of the valve 5, a connecting flange 7 fixedly connected to the outer wall of the downstream pipe 6, a fixing hole 8 provided on the connecting flange 7, a sewage pipe 2 connected to the side surface of the connecting pipe 4, and a treatment shell 3 connected to the lower end of the sewage pipe 2.

[0022] Specifically: When the ball valve body 1 needs to be drained, the valve 5 is closed, sealing the downstream pipeline 6. The natural gas and impurities in the ball valve body 1 cannot continue to flow to the downstream pipeline 6, but can only enter the drain pipe 2 through the connecting pipeline 4, and finally reach the treatment shell 3.

[0023] A bracket 10 is fixedly connected to the inner surface of the processing housing 3. A rotating shaft 19 is rotatably connected to the inner surface of the bracket 10. A rotating groove 15 is provided on the bracket 10. A slider 16 is fixedly connected to the outer wall of the rotating shaft 19 and is rotatably connected inside the rotating groove 15. A fan blade 14 is fixedly connected to the upper end of the rotating shaft 19. An arc-shaped push plate 11 is fixedly connected to the outer wall of the rotating shaft 19. A socket 17 is provided on the processing housing 3. A magnetic sheet 18 is movably connected to the inner surface of the socket 17. The magnetic sheet 18 passes through the socket 17. 7 penetrates into the interior of the processing housing 3. The inner surface of the processing housing 3 is connected to a connecting pipe 20. A storage interlayer 21 is provided between the connecting pipe 20 and the processing housing 3. A cleaning pipe 31 is fixedly connected to the side surface of the processing housing 3. A sealing plug 32 is movably connected to the inner surface of the cleaning pipe 31. Four screw holes 28 are provided on both the cleaning pipe 31 and the sealing plug 32. The four screw holes 28 are symmetrically arranged. A fixing bolt 29 is threadedly connected to the inner wall of the screw hole 28. A knob 30 is fixedly connected to one end of the fixing bolt 29.

[0024] Specifically: After natural gas enters the processing casing 3, it has a certain flow rate and pressure, which drives the fan blade 14 to rotate. The fan blade 14 is fixed on the rotating shaft 19, so it drives the rotating shaft 19 to rotate. At the same time, the rotating shaft 19 drives the arc-shaped push plate 11 fixedly connected to the outer wall to rotate. During the rotation, the arc-shaped push plate 11 pushes the larger impurities in the natural gas to the surrounding area. A magnetic sheet 18 is movably connected in the insertion hole 17 on the processing casing 3. The magnetic sheet 18, which extends into the processing casing 3, will attract magnetic materials (such as iron filings) in the impurities, thus achieving the initial separation of these impurities. After being pushed by the arc-shaped push plate 11 and attracted by the magnetic sheet 18, the remaining impurities eventually fall into the storage jacket 21 for temporary storage. After a certain amount of impurities accumulate in the storage jacket 21, the impurities can be cleaned through the cleaning pipe 31. During cleaning, first unscrew the fixing bolt 29 and the knob 30, open the sealing plug 32 to discharge the impurities, and then reinstall the sealing plug 32.

[0025] A through hole 13 is provided on the connecting pipe 20. A filter screen 12 is fixedly connected to the inner wall of the through hole 13. The lower end of the connecting pipe 20 is connected to a return pipe 9. The other end of the return pipe 9 is connected to the side surface of the downstream pipe 6. Three slide rails 22 are connected through the inner surface of the return pipe 9. A screen 23 is slidably connected to the inner surface of each of the three slide rails 22. A connecting plate 24 is fixedly connected to the front surface of the three screens 23. A handle 25 is fixedly connected to the front surface of the connecting plate 24.

[0026] Specifically: Natural gas in storage jacket 21 flows out through through hole 13 on connecting pipe 20. Filter screen 12 in through hole 13 filters the natural gas to prevent impurities in storage jacket 21 from flowing out. After preliminary filtration, the natural gas enters return pipe 9. There are three slide rails 22 in return pipe 9, and screens 23 are slidably connected to the slide rails 22. When natural gas passes through the three screens 23, it is further screened to remove smaller particulate impurities, thereby improving the purity and quality of natural gas. After filtration, the natural gas returns to the downstream pipeline 6 through return pipe 9 and continues to be transported normally in the pipeline system. When screen 23 needs to be cleaned or replaced, it can be pulled out along slide rail 22 by handle 25 for the corresponding maintenance operation and then inserted back into its original position.

[0027] Working principle: When the ball valve body 1 needs to be drained, valve 5 closes, sealing the downstream pipe 6. The natural gas and impurities in the ball valve body 1 cannot continue to flow to the downstream pipe 6, but can only enter the drain pipe 2 through the connecting pipe 4, and finally reach the treatment shell 3. After the natural gas enters the treatment shell 3, it has a certain flow rate and pressure, which drives the fan blade 14 to rotate. The fan blade 14 is fixed on the rotating shaft 19, so it will drive the rotating shaft 19 to rotate. At the same time, the rotating shaft 19 drives the arc-shaped push plate 11 fixedly connected to the outer wall to rotate. During the rotation, the arc-shaped push plate 11 will push the larger impurities in the natural gas to the surroundings. A magnetic sheet 18 is movably connected in the insertion hole 17 on the treatment shell 3. The magnetic sheet 18 extending into the treatment shell 3 will attract magnetic substances (such as iron filings) in the impurities. This process achieves initial separation of impurities. After being pushed by the arc-shaped pusher plate 11 and adsorbed by the magnetic sheet 18, the remaining impurities eventually fall into the storage jacket 21 for temporary storage. The natural gas in the storage jacket 21 flows out through the through hole 13 on the connecting pipe 20. The filter screen 12 in the through hole 13 filters the natural gas to prevent the impurities in the storage jacket 21 from flowing out. The natural gas that has undergone initial filtration enters the return pipe 9. There are three slide rails 22 in the return pipe 9. The slide rails 22 are slidably connected to the screens 23. When the natural gas passes through the three screens 23, it will be further screened to remove smaller particulate impurities, thereby improving the purity and quality of the natural gas. The filtered natural gas returns to the downstream pipeline 6 through the return pipe 9 and continues to be transported normally in the pipeline system.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
