Description

Technical Field

[0001] This utility model relates to the field of valve pressure regulation technology, and more specifically, to a valve pressure regulation device. Background Technology

[0002] In the field of modern fluid control systems, valves, as core control components, play a crucial role in industrial production, municipal facilities, energy transmission, and numerous specialized applications. However, they suffer from significant functional defects and technical limitations in practical applications.

[0003] Firstly, the fundamental problem of insufficient output pressure regulation capability is prevalent in mainstream valve pressure regulating devices. Traditional valves mostly adopt fixed parameter designs, and their output pressure is usually a preset fixed value or a limited number of preset values. They lack the technical means to accurately, continuously, and intelligently regulate the output pressure. This rigid design mode is particularly limited when facing complex and ever-changing working environments, diverse process requirements, and application scenarios with different media characteristics. For example, in chemical production processes, different reaction stages may require precise control of different pressure environments; in water supply systems, water supply pressure needs to be adjusted accordingly for different time periods and water consumption; in the field of precision equipment manufacturing, different process steps may require precise control of pneumatic or hydraulic system pressure. Because the output pressure cannot be flexibly adjusted according to actual usage needs, it often leads to low system operating efficiency, serious energy waste, and even safety hazards such as fluid impact and equipment damage due to pressure mismatch. This lack of pressure adaptability not only reduces the accuracy and reliability of fluid control systems but also increases energy consumption and maintenance costs.

[0004] Secondly, although some manufacturers in the industry have recognized this technological shortcoming and have initially achieved flexible adjustment of the internal flow area of ​​the pipeline to indirectly control the output pressure, these regulating mechanisms have shown significant instability in actual operation. Specifically, under long-term high-pressure or pressure-fluid operating conditions, the regulating device is often affected by a combination of adverse factors, such as strong impacts from the fluid inside the pipeline, changes in pressure fluctuation transmission, system vibration, and external mechanical interference. This leads to unpredictable slight displacements in the position of the precisely adjusted components. These seemingly minor physical changes can cause a significant deviation between the actual output fluid pressure and the set value, causing the originally carefully adjusted pressure parameters to gradually drift or suddenly change during operation. This instability not only affects the consistency and reliability of system operation but may also cause equipment damage, pipeline rupture, or production accidents when the fluid pressure changes suddenly. In addition, frequent failures of the regulating mechanism will increase the system's maintenance frequency and calibration costs, reduce the overall service life and economic benefits of the equipment, and bring continuous technical troubles and safety hazards to operators.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a valve pressure regulating device, which has the following features:

[0018] Beneficial effects:

[0019] 1. The regulating device, through the scientific coordination of fixed pipe, regulating sleeve, connecting pipe, regulating frame, regulating block, linkage rod, and linkage sleeve, effectively solves the technical problem of traditional valves being unable to flexibly adapt and adjust output pressure. Compared with valves designed with fixed parameters in existing technologies, this device adopts an innovative pressure regulating mechanism, which can achieve precise adjustment of output pressure according to different working conditions and process requirements. This scientific regulating mechanism enables the valve to adapt to various working conditions, from different reaction stages in chemical production to different water consumption periods in water supply systems, eliminating the limitations brought about by fixed parameter design. Compared with traditional single-pressure valves, this device significantly improves the accuracy and reliability of the fluid control system, reduces energy consumption and maintenance costs, and avoids fluid shock and equipment damage that may be caused by pressure mismatch. It provides users with a more precise and efficient control experience, meeting the needs of modern fluid control fields for equipment multifunctionality and adaptability.

[0020] 2. The locking mechanism is precisely assembled from components such as an adapter plate, locking sleeve, adapter hole, adapter groove, moving spring, push rod, push plate, fixed block, locking block, locking spring, locking block, and moving block. This effectively solves the problem of insufficient stability after pressure adjustment in existing technologies. Compared with devices on the market that have simple structures and are easily affected by pressure fluctuations leading to displacement of the adjusting components, this mechanism features a multi-locking system to ensure the stability of the adjusting device under high-pressure impact and equipment vibration. After pressure adjustment, the locking spring resets and pulls the locking block to slide inward along the locking rail and locking groove, allowing the locking wheel to precisely engage between two adjacent locking blocks to form the first layer of locking. Simultaneously, through the rotation of the adapter plate, the moving spring resets and pushes the moving block to rotate along the moving hole. The automatic reset mechanism, when the adapter plate rotates in the opposite direction, uses the push rod and top push plate to limit and support the locking sleeve to one side of the adapter plate. Combined with the limiting action of the slider in the groove, this ensures that the inner wall of the locking sleeve precisely limits the outer wall of the locking wheel, forming a second layer of locking. This double-safety mechanism maintains the precise position of the regulating component even under high-pressure impact and continuous vibration, completely solving the problem of parameter drift that easily occurs in traditional regulating devices under pressure fluctuation conditions. This highly stable design not only ensures the reliability and stability of the valve pressure parameters after adjustment, avoiding equipment damage, pipeline rupture, or production accidents that may be caused by sudden pressure fluctuations, but also effectively extends the valve's maintenance cycle and overall service life, reduces maintenance costs, and provides users with a stable and reliable fluid control experience.

[0030] Please see Figures 1-5A valve pressure regulating device includes a valve body 1. An regulating device is provided on one side of the valve body 1. The regulating device includes a fixed pipe 2, an regulating sleeve 3, a connecting pipe 4, an regulating frame 5, an regulating block 6, a linkage rod 7, and a linkage sleeve 8. The two ends of the regulating sleeve 3 are rotatably connected to the connecting pipe 4 and the fixed pipe 2, respectively. The regulating frame 5 is movably disposed in the connecting pipe 4, and the regulating block 6 is movably disposed in the connecting pipe 4. The linkage rod 7 is fixedly connected to one end of the regulating frame 5. The linkage sleeve 8 is fixedly installed inside the regulating sleeve 3, and its inner wall is threadedly installed on the outside of the linkage rod 7. A locking mechanism is installed on the outside of the fixed pipe 2. The locking mechanism includes an adapter plate 9, a locking sleeve 10, an adapter hole 11, an adapter groove 12, a moving spring 13, a push rod 14, a push plate 15, and a fixed... The system includes a fixed block 16, a locking block 17, a locking spring 18, a locking block 19, and a movable block 20. An adapter plate 9 is rotatably mounted on the outside of the fixed tube 2. A locking sleeve 10 is slidably mounted on the outside of the fixed tube 2. An adapter hole 11 is opened at one end of an adapter groove 12, which is opened on the adapter plate 9. A push rod 14 is fixedly connected to one side of the locking sleeve 10. Two push plates 15 are fixedly mounted on the push rod 14. A fixed block 16 is fixedly mounted on the outside of the fixed tube 2. Multiple locking blocks 17 are fixedly mounted on the outside of the fixed tube 2. The two ends of the locking spring 18 are respectively connected to two adjacent locking blocks 19. The locking block 19 is movably mounted on one side of the adjusting sleeve 3. The movable block 20 is fixedly mounted on one side of the adapter plate 9. The two ends of the movable spring 13 are respectively connected to the movable block 20 and the fixed block 16.

[0031] One end of the valve body 1 is connected to an input pipe 21, and the other end of the valve body 1 is connected to an output pipe 22. A screw 23 is fixedly connected to one side of the connecting pipe 4, and a screw sleeve 24 is detachably provided on one side of the output pipe 22. The screw sleeve 24 is detachably installed on the outside of the screw 23 by means of threads.

[0032] In this embodiment, when the output pressure at the valve output end needs to be adjusted according to requirements, the adapter plate 9 is first rotated forward, causing the adapter hole 11 and adapter groove 12 to rotate forward. The adapter plate 9 also causes the movable block 20 mounted on one side to rotate forward. Then, the movable block 20 causes the movable rod 35 to rotate forward along the movable hole 34. The movable block 20 then cooperates with the fixed block 16 to compress the movable spring 13. When the movable spring 13 is compressed to its limit, the adapter hole 11 rotates to a position concentric with the push plate 15, then pushes the locking sleeve 10. The locking sleeve 10 causes the inner slider 37 to slide along the slide groove 36, and the locking sleeve 10 also... The push rod 14 and the push plate 15 gradually slide through the adapter hole 11. At the same time, the locking sleeve 10 and the adapter plate 9 cooperate to compress the push spring 28. When the push spring 28 is compressed to its limit, the push plate 15 near the locking sleeve 10 just passes through the adapter hole 11 and moves to the other side of the adapter plate 9. Then the adapter plate 9 is released, and the moving spring 13 pushes the moving block 20 to rotate in the opposite direction. This causes the moving block 20 to drive the moving rod 35 to rotate in the opposite direction along the moving hole 34. The moving block 20 will also drive the adapter hole 11 and the adapter groove 12 to rotate in the opposite direction through the adapter plate 9. Then the push rod 14 will enter the adapter groove 12. The push rod 14 then cooperates with the push plate 10 near the locking sleeve 10. A push plate 15 limits the locking sleeve 10 to one side of the adapter plate 9. Then, the locking sleeve 10 no longer limits the outer side of the locking wheel 29. Then, the adjusting sleeve 3 rotates forward. The adjusting sleeve 3 will drive the locking rail 30 on one side to rotate, so that the locking rail 30 and the locking groove 31 cooperate to drive the locking block 19 to rotate forward. Then, the locking block 19 will drive the locking wheel 29 to move out from between the two locking blocks 17. Then, the locking wheel 29 will drive the locking block 19 to slide outward along the locking rail 30 and the locking groove 31, so that the locking block 19 drives the locking spring 18 to stretch outward. At the same time, the adjusting sleeve 3 will drive the inner linkage sleeve 8 to rotate forward. Since the linkage sleeve 8 and the linkage rod 7 are connected by threads... The movable connection, as well as the linkage rod 7 and the adjusting bracket 5, do not rotate. Then, the linkage rod 7 will drive the adjusting bracket 5 to slide, causing the adjusting bracket 5 to drive the outer inclined groove 32 to slide. Due to the conical structure design of the adjusting bracket 5, and the inclined structure design of the inclined groove 32 and the inclined block 33, when the adjusting bracket 5 drives the inclined groove 32 to slide, the inclined block 33 will slide in the inclined groove 32, causing the adjusting block 6 to drive the guide groove 26 opened on one side to slide outward along the guide block 25. At the same time, the adjusting block 6 will drive the adjusting hole 27 to move outward. The movement of the adjusting hole 27 and the change in the position of the adjusting block 6 expand the flow area inside the connecting pipe 4, thereby realizing the adjustment of the valve output pressure.

[0033] Please see Figures 3-5 As a further implementation of the overall equipment: a guide block 25 is fixedly provided on the inner side of the connecting pipe 4, a guide groove 26 is provided on one side of the adjusting block 6, the guide block 25 is located in the guide groove 26, and a plurality of adjusting holes 27 are provided on the adjusting block 6.

[0034] A push spring 28 is provided on the outside of the push rod 14. The push spring 28 is connected to one side of the locking sleeve 10, and the other end of the push spring 28 is in contact with the adapter plate 9.

[0035] A locking wheel 29 is provided on one side of the locking block 19. The locking wheel 29 is inserted between two locking blocks 17. Multiple locking rails 30 are fixed on one side of the adjusting sleeve 3. A locking groove 31 is opened on one side of the locking block 19. The locking groove 31 is adapted to the locking rail 30.

[0036] An inclined groove 32 is provided on the outer side of the adjusting frame 5, and an inclined block 33 is slidably provided in the inclined groove 32. The inclined block 33 is fixedly installed on the inner side of the adjusting block 6.

[0037] A movable hole 34 is provided in the fixed block 16, and a movable rod 35 is connected to one side of the movable block 20. One end of the movable rod 35 slides into the movable hole 34.

[0038] A groove 36 is provided on the outer side of the fixed tube 2, and a slider 37 is fixed on the inner side of the locking sleeve 10. The slider 37 slides in the groove 36.

[0039] More specifically, after the output pressure at the valve output end is adjusted appropriately, the rotation of the adjusting sleeve 3 is stopped, and the locking rail 30 and locking groove 31 cooperate to move the locking block 19 and locking wheel 29 between the corresponding two locking blocks 17. Then, the locking spring 18 resets and pulls the locking block 19 to slide inward along the locking rail 30 and locking groove 31, so that the locking block 19 drives the locking wheel 29 to engage between the corresponding two locking blocks 17. Then, the adapter plate 9 is rotated forward again, so that the adapter plate 9 drives the adapter hole 11 and adapter groove 12 to rotate forward again, and the moving block 20 drives the moving rod 35 to rotate forward along the moving hole 34. At the same time, the moving block 20 and the fixed block 16 cooperate again to squeeze the moving spring 13. When the adapter hole 11 rotates to the position concentric with the push plate 15 again, the push spring 28 pushes the locking sleeve 10 to drive the inner slider 37 to slide and reset along the slide groove 36. The locking sleeve 10 will drive the two locks through the push rod 14 on one side. The push plate 15 slides back to its original position. When the push spring 28 is fully reset, the push plate 15 at the top of the push rod 14 moves back to the original side of the adapter plate 9. Then the adapter plate 9 is released again, and the moving spring 13 pushes the moving block 20 to rotate and reset. Then the moving block 20 drives the moving rod 35 to rotate and reset along the moving hole 34. At the same time, the moving block 20 drives the adapter hole 11 and the adapter groove 12 to rotate and reset to a position that does not correspond to the push rod 14 and the push plate 15 through the adapter plate 9. Then the push rod 14, together with the top push plate 15, supports the locking sleeve 10 to one side of the adapter plate 9. With the slider 37 and the groove 36 limiting the locking sleeve 10, the locking sleeve 10 cannot move. Then the inner wall of the locking sleeve 10 limits the outer side of the locking wheel 29 again, so that the locking wheel 29 and the locking block 19 cannot move outward. This achieves the rotation limit of the adjusting sleeve 3, thereby ensuring the structural stability after the output pressure is adjusted and ensuring stable use.

[0040] In summary, during the use or operation of the overall equipment: when it is necessary to adjust the output pressure at the valve output end according to requirements, firstly, rotate the adapter plate 9 in the forward direction, causing the adapter hole 11 and adapter groove 12 to rotate in the forward direction. The adapter plate 9 will also cause the movable block 20 installed on one side to rotate in the forward direction. Then, the movable block 20 will cause the movable rod 35 to rotate in the forward direction along the movable hole 34. The movable block 20 will then cooperate with the fixed block 16 to compress the movable spring 13. When the movable spring 13 is compressed to its limit, the adapter hole 11 will rotate to a position concentric with the push plate 15, and then push the locking sleeve 10. The locking sleeve 10 will cause the inner slider 37 to slide along the slide groove 36, and... The locking sleeve 10 causes the push rod 14 and push plate 15 to gradually slide through the adapter hole 11. At the same time, the locking sleeve 10 and the adapter plate 9 cooperate to compress the push spring 28. When the push spring 28 is compressed to its limit, the push plate 15 near the locking sleeve 10 just passes through the adapter hole 11 and moves to the other side of the adapter plate 9. Then the adapter plate 9 is released, and the moving spring 13 pushes the moving block 20 to rotate in the opposite direction. This causes the moving block 20 to drive the moving rod 35 to rotate in the opposite direction along the moving hole 34. The moving block 20 also drives the adapter hole 11 and the adapter groove 12 to rotate in the opposite direction through the adapter plate 9. Then the push rod 14 enters the adapter groove 12 and then moves closer to the lock. One of the push plates 15 of the locking sleeve 10 limits the locking sleeve 10 to one side of the adapter plate 9. Then, the locking sleeve 10 no longer limits the outer side of the locking wheel 29. Then, the adjusting sleeve 3 rotates forward. The adjusting sleeve 3 will drive the locking rail 30 on one side to rotate, so that the locking rail 30 and the locking groove 31 cooperate to drive the locking block 19 to rotate forward. Then, the locking block 19 will drive the locking wheel 29 to move out from between the two locking blocks 17. Then, the locking wheel 29 will drive the locking block 19 to slide outward along the locking rail 30 and the locking groove 31, so that the locking block 19 drives the locking spring 18 to stretch outward. At the same time, the adjusting sleeve 3 will drive the inner linkage sleeve 8 to rotate forward. Since the linkage sleeve 8 and the linkage rod 7 are connected by threads... When the linkage 7 and the adjusting frame 5 are connected, they do not rotate. The linkage 7 then drives the adjusting frame 5 to slide, causing the adjusting frame 5 to slide along the outer inclined groove 32. Due to the conical structure design of the adjusting frame 5 and the inclined structure design of the inclined groove 32 and the inclined block 33, when the adjusting frame 5 drives the inclined groove 32 to slide, the inclined block 33 will slide in the inclined groove 32. This causes the adjusting block 6 to drive the guide groove 26 opened on one side to slide outward along the guide block 25. At the same time, the adjusting block 6 will drive the adjusting hole 27 to move outward. The movement of the adjusting hole 27 and the change in the position of the adjusting block 6 expand the flow area inside the connecting pipe 4, thereby realizing the adjustment of the valve output pressure.

[0041] After the output pressure at the valve output end is adjusted appropriately, stop rotating the adjusting sleeve 3, and allow the locking rail 30 and locking groove 31 to cooperate in moving the locking block 19 and locking wheel 29 between the corresponding two locking blocks 17. Then, the locking spring 18 resets and pulls the locking block 19 to slide inward along the locking rail 30 and locking groove 31, so that the locking block 19 drives the locking wheel 29 to engage between the corresponding two locking blocks 17. Then, rotate the adapter plate 9 forward again, so that the adapter plate 9 drives the adapter hole 11 and adapter groove 12 to rotate forward again, and the moving block 20 drives the moving rod 35 to rotate forward along the moving hole 34. At the same time, the moving block 20 and the fixed block 16 cooperate again to squeeze the moving spring 13. When the adapter hole 11 rotates to the position concentric with the push plate 15, the push spring 28 pushes the locking sleeve 10 to drive the inner slider 37 to slide and reset along the slide groove 36. The locking sleeve 10 will drive the two tops through the push rod 14 on one side. The push plate 15 slides back to its original position. When the push spring 28 is fully reset, the push plate 15 at the top of the push rod 14 moves back to the original side of the adapter plate 9. Then the adapter plate 9 is released again, and the moving spring 13 pushes the moving block 20 to rotate and reset. Then the moving block 20 drives the moving rod 35 to rotate and reset along the moving hole 34. At the same time, the moving block 20 drives the adapter hole 11 and the adapter groove 12 to rotate and reset to a position that does not correspond to the push rod 14 and the push plate 15 through the adapter plate 9. Then the push rod 14, together with the top push plate 15, supports the locking sleeve 10 to one side of the adapter plate 9. With the slider 37 and the groove 36 limiting the locking sleeve 10, the locking sleeve 10 cannot move. Then the inner wall of the locking sleeve 10 limits the outer side of the locking wheel 29 again, so that the locking wheel 29 and the locking block 19 cannot move outward. This achieves the rotation limit of the adjusting sleeve 3, thereby ensuring the structural stability after the output pressure is adjusted and ensuring stable use.

[0042] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
