Description

Technical Field

[0001] The present invention relates to the technical field of valve manufacturing, and particularly to a fireproof ball valve for high-flow pipelines. Background Art

[0002] In industrial and civil fields such as petrochemical industry, energy transmission, and urban gas, high-flow pipeline systems undertake the transmission tasks of a large amount of fluid media. Existing valves generally lack integrated pressure monitoring and alarm devices, and cannot timely sense sudden pressure changes in the pipeline to issue early warnings, making it difficult to timely discover and handle potential safety hazards; even if a few valves are equipped with a pressure alarm function, its alarm trigger mechanism is independent of the safety control mechanism of the valve, and it is impossible to automatically close and safely isolate the valve when the pressure is abnormal, presenting serious safety risks. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a fireproof ball valve for high-flow pipelines, which solves the problem of inability to issue early warnings in a timely manner.

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: It includes a valve pipe assembly, both ends of the valve pipe assembly are fixedly connected with disassembly and assembly components, a ball valve assembly is fixedly connected inside the valve pipe assembly, a locking assembly is fixedly connected to the outer wall of the valve pipe assembly, and an alarm assembly is fixedly connected to the outer wall of the valve pipe assembly, on the side of the alarm assembly close to the locking assembly; the locking assembly is used to ensure that the valve pipe assembly remains in a fixed state under specific conditions, preventing accidental movement or disassembly. At the same time, an alarm assembly is also fixedly connected to the outer wall of the valve pipe assembly. The function of this alarm assembly is to emit an alarm signal when an abnormal situation is detected. It should be noted that the alarm assembly is designed and installed on the side close to the locking assembly. Such a layout enables the alarm assembly to more effectively monitor abnormal situations related to locking under the locked state, thereby improving the safety and reliability of the entire system.

[0005] The locking assembly includes a connecting cylinder, an actuating component is slidably connected to the inner wall of the connecting cylinder. The actuating component includes a sliding rod, an arc-shaped push rod is movably connected to the outer wall below the sliding rod, one end of the arc-shaped push rod away from the actuating component is movably connected to a connecting plate, a first telescopic rod is fixedly connected to the side of the connecting plate close to the arc-shaped push rod, a guiding rod is fixedly connected to the connection between the connecting plate and the arc-shaped push rod, a second telescopic rod is fixedly connected to the side of the connecting plate away from the arc-shaped push rod, a second thrust spring is sleeved on the outer wall of the second telescopic rod, and a sealing plate structure is fixedly connected to the end of the second telescopic rod and the second thrust spring away from the connecting plate; through the mutual cooperation of all the above parts, it can drive the sealing plate structure to move horizontally, thereby achieving the effect of ventilation and closing of the valve pipe assembly, and effectively blocking the spread of fire.

[0006] The sealing plate structure includes a first moving plate. The inner wall of the first moving plate is fixedly connected with a second mounting plate. The side of the second mounting plate away from the first telescopic rod is fixedly connected with a third telescopic rod. To ensure the stability and functionality of the structure, a third thrust spring is sleeved on the outer wall of the third telescopic rod to provide necessary elastic support. A clamping ring is fixedly connected to the inner wall of the first moving plate. The end of the third telescopic rod away from the second mounting plate is fixedly connected with a second moving plate. An oil discharge channel communicating with the sealing plate structure is provided in the inner wall of the valve core. When the valve core is closed, under the action of the third telescopic rod and the third thrust spring, the second moving plate squeezes and discharges the residual oil in the valve core through the oil discharge channel to a specific collection area of the valve pipe assembly. In this way, a complete sealing plate structure is formed, which can discharge the residual oil inside the valve core when the valve core is closed.

[0007] Preferably, locking holes are provided on the outer wall of the connecting cylinder. A locking structure is fixedly connected to the outer wall of the top of the pressing assembly to ensure the stability of the pressing assembly during use. An activity rod is movably connected to the top of the pressing assembly. One end of the activity rod away from the pressing assembly is movably connected to a support rod. A assembling handle is threadedly connected to the end of the activity rod close to the support rod, which is convenient for users to carry out assembling and disassembling operations. The sliding rod and the arc-shaped push rod are movably connected through a movable shaft, and the arc-shaped push rod and the connecting plate are movably connected through a rotating shaft, ensuring the correct guiding of the assembly during movement. The guiding rod is installed on the outer wall of the rotating shaft, and an auxiliary spring is sleeved on the outer wall of the sliding rod to ensure that the pressing assembly can quickly reset during operation.

[0008] Preferably, the locking structure includes a bolt. A first thrust spring is sleeved on the outer wall of the bolt, and its function is to provide an outward thrust for the bolt. One end of the bolt close to the pressing assembly is inserted into the inner wall of the locking hole to maintain a stable position, thereby realizing the locking function.

[0009] Preferably, the alarm component includes an installation cylinder. A first mounting plate is fixedly connected inside the installation cylinder. One end of a tension spring is fixedly connected to the outer wall of the first mounting plate, and the other end of the tension spring away from the first mounting plate is fixedly connected to a sliding plate. A sealing gasket is attached to the outer wall of the sliding plate, and a thimble is fixedly connected to the outer wall of the sealing gasket. A sound-generating structure is connected through the upper part of the installation cylinder. A rubber ball is movably connected inside the sound-generating structure. A pressure relief pipe is connected through the outer wall of the installation cylinder. A pressure relief valve is arranged at the end of the pressure relief pipe away from the installation cylinder to ensure that the system can safely release pressure when the pressure is too high, preventing damage caused by overpressure. Moreover, the installation cylinder is a sealed structure, filled with hydrogen gas at a pre-set pressure inside. An anti-hydrogen penetration coating is applied to the inner wall of the installation cylinder. At the same time, the closed pressure relief valve makes the installation cylinder form a closed state to ensure the long-term and stable existence of hydrogen gas. Hydrogen gas is filled when the pressure relief valve arranged inside the pressure relief pipe is opened.

[0010] Preferably, the sliding plate is slidably connected to the installation cylinder. The sliding connection between the sliding plate and the installation cylinder enables the sliding plate to move flexibly when subjected to external forces. The end of the pressure relief pipe away from the installation cylinder is connected through a buffer chamber, and the design of this buffer chamber can further enhance the safety performance of the system, ensuring effective pressure release under high-pressure conditions and avoiding system damage.

[0011] Preferably, the sound-generating structure includes a protective cover. A battery is fixedly connected above the inside of the protective cover. A loudspeaker is connected through the outer wall of the protective cover, which is responsible for amplifying the sound of the alarm signal to achieve the purpose of reminding the user. An alarm is fixedly connected below the battery. The alarm is triggered when receiving a specific signal and works in cooperation with the loudspeaker to emit an alarm sound.

[0012] Preferably, the disassembly and assembly component includes a collar. A fourth telescopic rod is fixedly connected to the inner wall of the collar. A fourth thrust spring is sleeved on the outer wall of the fourth telescopic rod. Such a design enables the telescopic rod to have a certain elastic recovery ability when subjected to external forces. The ends of the fourth telescopic rod and the fourth thrust spring away from the collar are both fixedly connected to an arc-shaped flange. Such a connection method ensures the stability and reliability of the component during disassembly and assembly. A corrugated plate is movably connected between the collar and the arc-shaped flange. The presence of the corrugated plate not only increases the flexibility of the component but also can absorb and disperse the forces acting on the component to a certain extent, thereby protecting the entire disassembly and assembly component from damage.

[0013] Preferably, the ball valve component includes a valve core. A guiding groove is opened on the inner wall of the valve core. Through the guiding groove, the sealing plate structure can move horizontally left and right. Sliding grooves are opened on both the upper and lower sides of the guiding groove. Through the sliding grooves, the sealing plate structure can slide left and right, providing additional sliding space to adapt to different working conditions and requirements.

[0014] Preferably, the guiding groove and the guiding rod are slidably connected. This connection method ensures that the guiding rod can slide smoothly in the guiding groove, thereby ensuring the stability and accuracy of the ball valve assembly during the opening and closing processes. The sliding groove and the first telescopic rod are slidably connected, enabling the first telescopic rod to freely expand and contract in the sliding groove, thereby providing greater operational flexibility and adaptability for the ball valve assembly.

[0015] The present invention provides a fireproof ball valve for high-flow pipelines. It has the following beneficial effects: (1). For this fireproof ball valve for high-flow pipelines, through the cooperation of the pressing component and the sealing plate structure in the locking component, the sealing plate structure is driven to move horizontally by parts such as the sliding rod and the arc-shaped push rod, realizing the ventilation and closing of the valve pipe assembly, effectively blocking the spread of fire; at the same time, when the sealing plate structure closes the valve core of the ball valve assembly, it can discharge the residual oil inside the valve core, and cooperate with the fire prevention function of the locking component to improve the system safety from two aspects of fire prevention and residue removal, reducing the fire hazard and the risk of residual medium.

[0016] (2). For this fireproof ball valve for high-flow pipelines, the temperature is transmitted through the first mounting plate of the alarm component. The hydrogen inside the installation cylinder starts to become active, which will push upward to make the thimble pierce into the inside of the rubber ball 28, triggering the alarm in the sound-producing structure and sounding an alarm through the loudspeaker. After the two ends of the valve pipe are closed, opening the pressure relief valve can transport the pressure inside the installation cylinder to the inside of the buffer cavity through the pressure relief pipe for pressure relief, achieving early warning and reducing the effect of fire occurrence.

[0017] (3). For this fireproof ball valve for high-flow pipelines, through the mutual cooperation of the collar, the fourth telescopic rod, the arc-shaped flange and the corrugated plate of the disassembly and assembly component, the fourth telescopic rod and the fourth thrust spring endow the component with elastic recovery ability, and the corrugated plate increases flexibility and disperses the force; at the same time, this component is fixedly connected to both ends of the valve pipe assembly. On the basis of realizing convenient disassembly and assembly, it provides stable support for the valve pipe, keeps the valve pipe stable during the disassembly and assembly process, and avoids structural damage and medium leakage caused by disassembly and assembly.

[0018] (4). For this fireproof ball valve for high-flow pipelines, the guiding groove of the ball valve assembly is slidably connected with the guiding rod of the locking component, and the sliding groove is slidably connected with the first telescopic rod, providing precise guidance for the sealing plate structure and ensuring the smooth and accurate opening and closing of the ball valve; at the same time, this guiding design cooperates with the movement control of the locking component, making the ball valve assembly operate flexibly under different working conditions, adapting to various working conditions requirements, and improving the working efficiency and applicability of the entire valve pipe system.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-10 , the present invention provides a technical solution: including a valve pipe assembly 1, both ends of the valve pipe assembly 1 are fixedly connected with a disassembly and assembly component 4, a ball valve component 5 is fixedly connected inside the valve pipe assembly 1, a locking component 3 is fixedly connected to the outer wall of the valve pipe assembly 1, and an alarm component 2 is fixedly connected to the outer wall of the valve pipe assembly 1, on the side of the alarm component 2 close to the locking component 3; the locking component 3 is used to ensure that the valve pipe assembly 1 remains fixed under specific conditions to prevent accidental movement or disassembly. At the same time, an alarm component 2 is also fixedly connected to the outer wall of the valve pipe assembly 1. The function of this alarm component 2 is to send an alarm signal when an abnormal situation is detected. The alarm component 2 is designed and installed on the side close to the locking component 3. Such a layout can enable the alarm component 2 to more effectively monitor abnormal situations related to locking in the locked state, thereby improving the safety and reliability of the entire system.

[0023] The locking component 3 includes a connecting cylinder 31. A pressing component 34 is slidably connected to the inner wall of the connecting cylinder 31. The pressing component 34 includes a sliding rod 341. An arc-shaped push rod 343 is movably connected to the outer wall below the sliding rod 341. One end of the arc-shaped push rod 343 away from the pressing component 34 is movably connected to a connecting plate 344.

A second telescopic rod 348 is fixedly connected to the side of the connecting plate 344 away from the arc-shaped push rod 343. A second thrust spring 346 is sleeved on the outer wall of the second telescopic rod 348. One end of the second telescopic rod 348 and the second thrust spring 346 away from the connecting plate 344 is fixedly connected to a sealing plate structure 347; through the mutual cooperation of all the above parts, it can drive the sealing plate structure 347 to move horizontally, thereby realizing the ventilation and closing effects of the valve pipe assembly 1, and effectively blocking the spread of fire.

[0024] The sealing plate structure 347 includes a first moving plate 3471. A second mounting plate 3472 is fixedly connected to the inner wall of the first moving plate 3471. A third telescopic rod 3474 is fixedly connected to the side of the second mounting plate 3472 away from the first telescopic rod 345. To ensure the stability and functionality of the structure, a third thrust spring 3473 is sleeved on the outer wall of the third telescopic rod 3474 to provide the necessary elastic support. A clamping ring 3475 is fixedly connected to the inner wall of the first moving plate 3471. One end of the third telescopic rod 3474 away from the second mounting plate 3472 is fixedly connected to a second moving plate 3476. In this way, a complete sealing plate structure is formed, which can discharge the residual oil inside the valve core when the valve core 51 is closed.

[0025] The outer wall of the connecting cylinder 31 is provided with a locking hole 32. A locking structure 33 is fixedly connected to the outer wall of the top of the pressing component 34 to ensure the stability of the pressing component during use. The top of the pressing component 34 is movably connected to a movable rod 36. One end of the movable rod 36 away from the pressing component 34 is movably connected to a support rod 35. One end of the movable rod 36 close to the support rod 35 is threadedly connected to an assembly handle 37, which is convenient for users to perform assembly and disassembly operations. The sliding rod 341 and the arc-shaped push rod 343 are movably connected through a movable shaft, and the arc-shaped push rod 343 and the connecting plate 344 are movably connected through a rotating shaft, ensuring the correct guiding of the components during movement. The guiding rod 349 is installed on the outer wall of the rotating shaft. An auxiliary spring 342 is sleeved on the outer wall of the sliding rod 341 to ensure that the pressing component can quickly reset during operation.

[0026] The locking structure 33 includes a latch 332. A first thrust spring 331 is sleeved on the outer wall of the latch 332, and its function is to provide an outward thrust for the latch 332. One end of the latch 332 close to the pressing component 34 is inserted into the inner wall of the locking hole 32 to maintain a stable position, thereby realizing the locking function.

[0027] The alarm component 2 includes an installation cylinder 21. A first installation plate 22 is fixedly connected inside the installation cylinder 21. A tension spring 23 is fixedly connected to the outer wall of the first installation plate 22. One end of the tension spring 23 away from the first installation plate 22 is fixedly connected to a sliding plate 24. A sealing gasket 25 is attached to the outer wall of the sliding plate 24. A thimble 210 is fixedly connected to the outer wall of the sealing gasket 25. A sound generating structure 27 is connected through the upper part of the installation cylinder 21. A rubber ball 28 is movably connected inside the sound generating structure 27. A pressure relief pipe 26 is connected through the outer wall of the installation cylinder 21. A pressure relief valve 29 is arranged at one end of the pressure relief pipe 26 away from the installation cylinder 21 to ensure that the system can safely release pressure when the pressure is too high and prevent damage caused by overpressure.

[0028] The sliding plate 24 is slidably connected to the installation cylinder 21. The sliding connection between the sliding plate 24 and the installation cylinder 21 is realized. Such a design allows the sliding plate 24 to move flexibly when subjected to an external force. One end of the pressure relief pipe 26 away from the installation cylinder 21 is connected through a buffer chamber. The design of this buffer chamber can further enhance the safety performance of the system and ensure that pressure can be effectively released under high-pressure conditions. The sound generating structure 27 includes a protective cover 271. A battery 272 is fixedly installed above the inside of the protective cover 271. A loudspeaker 273 is connected through the outer wall of the protective cover 271, which is responsible for amplifying the sound of the alarm signal to achieve the purpose of reminding users. An alarm 274 is fixedly connected below the battery 272. The alarm 274 will be triggered when receiving a specific signal and works in cooperation with the loudspeaker 273 to emit an alarm sound.

[0029] The disassembly and assembly component 4 includes a collar 41. The inner wall of the collar 41 is fixedly connected with a fourth telescopic rod 46. A fourth thrust spring 45 is sleeved on the outer wall of the fourth telescopic rod 46. Such a design enables the telescopic rod to have a certain elastic recovery ability when subjected to external forces. One end of the fourth telescopic rod 46 and the fourth thrust spring 45 away from the collar 41 are both fixedly connected with an arc-shaped flange 42. Such a connection method ensures the stability and reliability of the component during disassembly and assembly. A corrugated plate 43 is movably connected between the collar 41 and the arc-shaped flange 42. The presence of the corrugated plate 43 not only increases the flexibility of the component, but also provides an installation position for the arc-shaped flange 42 through the collar 41.

[0030] The ball valve component 5 includes a valve core 51. A guide groove 52 is opened on the inner wall of the valve core 51. Through the guide groove 52, the sealing plate structure 347 can move horizontally left and right. Sliding grooves 53 are opened on both the upper and lower sides of the guide groove 52. Through the sliding grooves, the sealing plate structure 347 can slide left and right, providing additional sliding space to adapt to different working conditions and requirements.

[0031] The guide groove 52 is slidably connected with a guide rod 349. Such a connection method ensures that the guide rod 349 can slide smoothly in the guide groove 52, thus ensuring the smoothness and accuracy of the ball valve component during the opening and closing processes. The sliding groove 53 is slidably connected with a first telescopic rod 345, enabling the first telescopic rod 345 to freely expand and contract in the sliding groove 53, thereby providing greater operation flexibility and adaptability for the ball valve component.

[0032] During use, the device is moved to the required installation position. Then, by the staff pulling the arc-shaped flange 42 arranged inside the disassembly and assembly component 4, the two arc-shaped flanges 42 can be horizontally moved away from each other. At the same time, the corrugated plate 43, the fourth thrust spring 45, and the fourth telescopic rod 46 are squeezed. When disassembly is required, the connected pipeline is taken out, and the two arc-shaped flanges 42 can drive the arc-shaped flange 42 to reset through the elasticity of the fourth thrust spring 45 itself, so that the device can adapt to butt joints of different sizes of pipelines and achieve the effect of quick disassembly and assembly. The collar 41 provides an installation position for the arc-shaped flange 42.

[0033] When it is necessary to open the valve pipe assembly 1, it is slidably connected to the inner wall of the connecting cylinder 31 of the locking assembly 3 through the pressing assembly 34. When the pressing assembly 34 works, the assembled handle 37 stored on the valve pipe assembly 1 is assembled. Then, the assembled assembled handle 37 is assembled with the movable rod 36. At the same time, the support rod 35 can provide an installation position for it. Then, the assembled handle 37 is lifted upward, and the assembled handle 37 rotates around the rotating shaft to achieve the lever principle, which can press the pressing slide rod 341 downward. The slide rod 341 drives the arc-shaped push rod 343 to rotate through the movable shaft. The other end of the arc-shaped push rod 343 pushes the connecting plate 344 to move horizontally through the rotating shaft. During this process, the guide rod 349 slides along the guide groove 52 on the inner wall of the valve core 51 of the ball valve assembly 5, playing an accurate guiding role. Then, through the snap ring 3475, it can prevent the second moving plate 3476 from being displaced when the oil is flowing.

[0034] When the connecting plate 344 moves, it drives the first telescopic rod 345 to slide in the chute 53. At the same time, the second telescopic rod 348 compresses the second thrust spring 346, pushing the sealing plate structure 347 to move towards the ventilation port of the valve pipe assembly 1. When the sealing plate structure 347 completely blocks the ventilation port, the locking structure 33 at the top of the pressing assembly 34 comes into play. The latch 332 is inserted into the locking hole 32 on the outer wall of the connecting cylinder 31 under the thrust of the first thrust spring 331, locking the pressing assembly 34, thereby maintaining the open state of the valve pipe assembly 1.

[0035] When the temperature fluctuation inside the valve pipe assembly 1 is too large, the gas inside the rubber ball 28 arranged inside the alarm assembly 2 is hydrogen. Since the boiling point is lower than that of the oil, when the temperature of the oil is too high, the temperature is transmitted to the first mounting plate 22. When the temperature of the first mounting plate 22 is too high, the hydrogen expands, thus pushing the slide plate 24 to slide upward. At the same time, through the sealing gasket 25, hydrogen leakage can be effectively avoided. Then, the upward moving slide plate 24 can drive the thimble 210 to move upward synchronously. When the spike at the top of the thimble 210 pierces the rubber ball 28 and continues to move upward, when the thimble 210 contacts the alarm 274 arranged inside the sound structure 27, the alarm 274 starts to work. The electrical signal emitted by the alarm 274 is powered by the battery 272 and will emit an alarm sound. Then, through the loudspeaker 273, the sound emitted by the alarm 274 can be amplified. At the same time, if the pressure inside the installation cylinder 21 is too high, the pressure can be released to the buffer cavity through the pressure relief pipe 26 via the pressure relief valve 29 to ensure the safety of the system. Then, through the buffer cavity, the released hydrogen can be buffered, thus achieving the warning effect. The tension spring 23 can drive the slide plate 24 to reset, which can effectively prevent the slide plate 24 from getting stuck during reset. Then, through the protective cover 271, the electronic components inside the protective cover 271 can be protected.

[0036] When a fire breaks out and the valve pipe assembly 1 needs to be closed, the bolt 332 is separated from the locking hole 32, so that the pressing assembly 34 can be unlocked. Then, the assembly handle 37 stored on the valve pipe assembly 1 is assembled. Then, the assembly handle 37 is pressed downward, and the assembly handle 37 rotates around the rotating shaft to achieve the lever principle, so that the pressing slide bar 341 can be lifted upward. Thus, the arc-shaped push rod 343 driven to move upward for reset can drive the sealing plate structure 347 to be reset synchronously. The first moving plate 3471 inside the reset sealing plate structure 347 can close the valve core 51. At the same time, the second mounting plate 3472 can provide an installation position for the first moving plate 3471, so as to prevent the fire from spreading to the inside of other pipes, reduce the fire hazard and the risk of residual medium. When the sealing plate structure 347 is working, after the valve core 51 is closed, the pressure inside is greater than the pressure outside, so that the third telescopic rod 3474 moves the second moving plate 3476 under the elastic force of the third thrust spring 3473, and discharges the residual oil inside the valve core 51 through a specific channel, avoiding the residual oil inside the valve core 51 and reducing the resistance suffered by the sealing plate structure 347 when closing the valve core 51. Then, the auxiliary spring 342 can play a role in guiding the downward pulling force when the slide bar 341 is pressed downward again.

[0037] When the valve pipe assembly 1 needs to be opened or closed, the pressing assembly 34 of the locking assembly 3 is operated to drive the sealing plate structure 347 to slide in the guide groove 52 and the chute 53 on the inner wall of the valve core 51. The sliding connection between the guide groove 52 and the guide rod 349 and the sliding connection between the chute 53 and the first telescopic rod 345 ensure the smooth and accurate movement of the sealing plate structure 347, realize the smooth opening and closing of the ball valve assembly 5, and meet the medium flow control requirements under different working conditions.
