Description

Technical Field

[0001] This disclosure relates to the field of safety valve technology, and in particular to a safety valve with an automatic locking function. Background Technology

[0002] A safety valve is a special valve whose opening and closing elements are normally closed under the action of external force. When the pressure of the medium in the equipment or pipeline rises above the specified value, it prevents the pressure of the medium in the pipeline or equipment from exceeding the specified value by discharging the medium to the outside of the system.

[0003] First, existing safety valves require pressure to raise the valve disc inside the system when discharging media, thereby releasing the media and reducing pressure. However, the existing valve disc is fixed by an O-ring, which poses a risk of detachment after prolonged use. This can lead to internal pressure leakage and media leakage into the pipeline. Second, after prolonged use, the valve disc of existing safety valves requires manual raising to clean the bottom of the disc and prevent valve failure. Additionally, the valve disc can stick to the valve core after extended use, preventing it from rising and causing excessive internal pressure, potentially leading to an explosion and endangering the lives of workers.

Support plates 42 are movably connected to both sides of the bottom end of the movable plate 33, located on both sides of the tie rod 29. A top plate 34 is movably connected to both sides of the bottom end of the movable plate 33, located on one side of the support plate 42. A first connecting shaft 35 is fixedly connected to both ends of the top plate 34. One end of the first connecting shaft 35 is movably sleeved... There is a top rod 38, one end of which is movably connected to a second connecting shaft 36. One end of the second connecting shaft 36 is fixedly connected to a moving block 37. The bottom end of the moving block 37 is fixedly connected to a sliding plate 41. One end of the moving block 37 is fixedly connected to a first electromagnet 39. One side of the first electromagnet 39 is movably connected to a second electromagnet 40. One side of the second electromagnet 40 is fixedly connected to a working shell 8. By providing a moving plate 33, a top plate 34, a first connecting shaft 35, a second connecting shaft 36, a moving block 37, a top rod 38, a first electromagnet 39, a sliding plate 41, and a support plate 42, it is beneficial to prevent the sealing gasket 18 from sticking to the valve core 12, which would prevent the valve from opening and cause excessive air pressure, leading to an explosion and endangering the lives of the workers.

[0030] Furthermore, a connecting buckle 26 is fixedly connected to the bottom end of the valve disc 17, a sealing gasket 18 is fixedly connected to the bottom end of the connecting buckle 26, the valve disc 17 is fixedly connected to the top end of the sealing gasket 18, and the valve core 12 is movably connected to the bottom end of the sealing gasket 18. The sealing gasket 18 helps to prevent the safety valve from leaking.

[0031] Furthermore, both the disassembly block 24 and the sealing block 25 are cone-shaped platforms. A fixing groove is provided on the outer side of the top of the valve disc 17. Both the disassembly block 24 and the sealing block 25 are located inside the fixing groove of the valve disc 17. The two ends of the fixing clip 19 are inclined and are adapted to the two ends of the disassembly block 24 and the sealing block 25.

[0032] Working principle: During installation, the valve disc 17 drives the push plate 20 to rise, which in turn drives the stop rod 22 to rise via the slider 21. The rise of the stop rod 22 causes the second spring 27 to move the fixing clip 19 to the inside of the fixing groove of the valve disc 17 via the moving rod 23, thus fixing the valve disc 17. When it is necessary to disassemble the valve disc 17, the operator rotates the valve disc 17, causing the disassembly block 24 to move the fixing clip 19. Simultaneously, the first spring 15 drives the stop rod 22 to descend via the push plate 20 and slider 21, causing the stop rod 22 to move to the inside of the slot of the moving rod 23. The safety valve is then installed via the fifth flange plate 11. After the safety valve reaches a fixed air pressure, the sealing... The sealing gasket 18 and valve disc 17 drive the backflushing plate 13 to rise. At the same time, the rising position of the backflushing plate 13 is controlled by the baffle tube 14. Simultaneously, the first electromagnet 39 and the second electromagnet 40 are energized, which connects the positive terminals of the motors of the first electromagnet 39 and the second electromagnet 40. This causes the first electromagnet 39 to drive the moving block 37 to move, which in turn drives the top plate 34 to rise via the push rod 38. This causes the moving plate 33 to rise, which in turn drives the backflushing plate 13 to rise via the pull rod 29. This prevents the sealing gasket 18 from sticking to the valve core 12, which would prevent the valve from opening, cause excessive air pressure, and lead to an explosion, thereby endangering the lives of the workers.
