Description

Technical Field

[0001] This utility model relates to the technical field of gas pressure regulating valve assembly, and more specifically, to a gas pressure regulating valve assembly. Background Technology

[0002] In the field of gas pressure regulating valve assemblies, the flow rate regulation accuracy of the diverter and the stability of the regulating structure directly affect the pressure control effect of gas delivery and the system operating efficiency. However, the gas pressure regulating valve assemblies currently on the market still have many technical defects in practical applications. These problems not only affect the pressure regulation effect, but may also lead to system instability and operational failures.

[0003] The primary problem is the inflexibility of flow rate regulation. Existing gas pressure regulating valve assemblies have significant defects: First, they cannot be independently adjusted for a single branch pipe, resulting in insufficient adjustment accuracy. In addition, this design deficiency not only reduces the adaptability of the system but may also lead to improper gas pressure due to improper adjustment, affecting the delivery effect and increasing energy consumption and operating costs.

[0004] More prominently, the regulating structure suffers from poor stability. Although some equipment achieves flexible flow rate adjustment through regulating mechanisms, serious problems exist: First, the regulating structure design is simple and lacks reliability. Impact forces during gas delivery can easily cause the internal structure to loosen, and the regulating components are prone to displacement after long-term operation. In addition, vibration and pressure fluctuations may cause structural changes. Finally, this design deficiency not only affects the accuracy of pressure regulation but may also lead to pressure runaway due to structural failure. This structural defect not only reduces the service life of the equipment but may also cause system failure due to poor stability, affecting production safety and operational efficiency.

[0032] Multiple main compartments 23 are detachably connected by bolts and nuts, and multiple interconnecting compartments 2 are detachably connected by threads. One end of one interconnecting compartment 2 is detachably connected by a threaded sealing cap 24.

[0033] In this embodiment, when the device is needed, the output flow rate of each fixed pipe 3 and output pipe 4 is first adjusted, and then the gas is connected to the gas conveying device through the input pipe 22 for conveying. Then the gas enters the main flow chamber 23 through the input pipe 22 and flows into the connecting chamber 2. Then it is distributed to each fixed pipe 3 through the connecting chamber 2 and finally conveyed to the subsequent equipment through each output pipe 4. The output flow rate of each fixed pipe 3 can be adjusted individually, thereby realizing the adjustment of the gas conveying pressure.

[0034] Please see Figure 4 and Figure 5 As a further implementation of the overall equipment: a spring 25 is movably sleeved on the outside of the shift rod 16, one end of the spring 25 is connected to the shift sleeve 13, and the other end of the spring 25 is in contact with the shift plate 17.

[0035] The adjusting sleeve 5 has multiple limiting blocks 26 on one side, and the locking block 14 has multiple limiting slots 27 on the inner side, which are adapted to the limiting blocks 26.

[0036] Multiple guide rails 28 are fixedly provided on the outside of the output tube 4, and a guide groove 29 is provided on the inside of the shift sleeve 13. The guide groove 29 is adapted to the guide rails 28.

[0037] Multiple slide rails 30 are fixedly provided on the inner wall of the regulating sleeve 6, and multiple slide grooves 31 are provided on the outer side of the adjusting rod 8. The slide grooves 31 are adapted to the slide rails 30.

[0038] A fixing plate 32 is fixedly installed inside the output pipe 4. The inner wall of the output pipe 4 is fixedly connected to the outer wall of the regulating sleeve 6 through the fixing plate 32. A connecting rod 33 is provided on the outer side of the control sleeve 10. The inner wall of the regulating sleeve 5 is fixedly connected to the control sleeve 10 through the connecting rod 33.

[0039] More specifically, when it is necessary to adjust the output flow rate of a single fixed tube 3, firstly, rotate the shift plate 17 in the forward direction. The shift plate 17 drives the shift block 11 installed on one side to rotate. Then, the shift block 11 and the limiting block 19 cooperate to compress the shift spring 12. At the same time, the shift plate 17 drives the shift hole 18 to rotate in the forward direction. When the shift spring 12 is compressed to its limit, the shift hole 18 just moves to a position concentric with the shift rod 16. Then, push the shift sleeve 13. The shift sleeve 13 drives the shift rod 16 to pass into the shift hole 18. The shift sleeve 13 will cooperate with the shift plate 17 to compress the spring 25. Then, the inner wall of the shift sleeve 13 no longer limits the outer wall of the locking wheel 21. Then, rotate the adjusting sleeve 5 in the forward direction. The adjusting sleeve 5 drives the limiting block on one side to rotate. When block 26 rotates clockwise, the limiting block 26 and the limiting groove 27 work together to drive the locking block 14 to rotate clockwise. The locking block 14 then drives the locking wheel 21, which is mounted on one side, to rotate clockwise. The locking wheel 21 then moves out from between the two circular blocks 20 and drives the locking block 14 to slide outwards along the limiting block 26 and the limiting groove 27. The locking block 14 then drives the linkage spring 15 to stretch. Simultaneously, the adjusting sleeve 5 drives the control sleeve 10 to rotate via the connecting rod 33. Because the slide rail 30 and the slide groove 31 limit the adjustment rod 8, the adjusting rod 8 and the control rod 9 cannot rotate. Meanwhile, because the control sleeve 10 is threaded and movably fitted onto the outside of the control rod 9, the control rod 9 drives the adjusting rod 8 to rotate along the slide rail 30 and the slide groove 31. The inner side of the control sleeve 6 slides, changing the number of adjustment holes 7 open on the side wall of the control sleeve 6, thus changing the flow area and achieving the purpose of adjusting the conveying speed and conveying pressure. After the adjustment is appropriate, the rotation of the control sleeve 5 is stopped, and the locking block 14 drives the locking wheel 21 to rotate between the corresponding two round blocks 20. Then, the linkage spring 15 resets and pulls the locking block 14 to slide inward along the limiting block 26 and the limiting groove 27. Then, the locking block 14 drives the locking wheel 21 on one side to lock into the corresponding two round blocks 20. Then, the shift sleeve 13 is released, and the spring 25 pushes the shift sleeve 13 to slide back to its original position along the guide rail 28 and the guide groove 29. The shift sleeve 13 also drives the shift rod 16 to slide back to its original position. When the spring 25 is fully reset, the shift... The shift rod 16 no longer limits the shift plate 17 through the shift hole 18. Then, the shift spring 12 pushes the shift block 11 to rotate in the opposite direction and reset. Then, the shift block 11 drives the shift hole 18 to rotate in the opposite direction and reset to a position that does not correspond to the shift rod 16 through the shift plate 17. Then, the shift rod 16 supports and limits the shift sleeve 13, and the guide rail 28 and guide groove 29 cooperate to limit the shift sleeve 13, so that the shift sleeve 13 cannot slide. Then, the inner wall of the shift sleeve 13 limits the outer wall of the locking wheel 21 again, so that the locking wheel 21 and the locking block 14 cannot slide outward, thereby limiting the adjustment sleeve 5 and preventing the adjustment sleeve 5 from rotating, thus ensuring the stability of the adjusted structure and thus ensuring the stable delivery of gas.

[0040] In summary, when the equipment is in use or operation: First, adjust the output flow rate of each fixed pipe 3 and output pipe 4. Then, connect the gas conveying device through the input pipe 22 for conveying. The gas then enters the main flow chamber 23 through the input pipe 22 and flows into the connecting chamber 2. It is then distributed to each fixed pipe 3 through the connecting chamber 2 and finally conveyed to the subsequent equipment through each output pipe 4. The output flow rate of each fixed pipe 3 can be adjusted individually, thereby realizing the adjustment of the gas conveying pressure.

[0041] When the output flow rate of a single fixed pipe 3 needs to be adjusted, firstly, rotate the shift plate 17 in the forward direction. The shift plate 17 drives the shift block 11 installed on one side to rotate. Then, the shift block 11 and the limiting block 19 cooperate to compress the shift spring 12. At the same time, the shift plate 17 drives the shift hole 18 to rotate in the forward direction. When the shift spring 12 is compressed to its limit, the shift hole 18 moves to a position concentric with the shift rod 16. Then, push the shift sleeve 13. The shift sleeve 13 drives the shift rod 16 to pass into the shift hole 18. The shift sleeve 13 and the shift plate 17 cooperate to compress the spring 25. Then, the inner wall of the shift sleeve 13 no longer limits the outer wall of the locking wheel 21. Then, rotate the adjusting sleeve 5 in the forward direction. The adjusting sleeve 5 drives the limiting block 26 on one side to rotate in the forward direction. The mechanism rotates, and then the limiting block 26 and the limiting groove 27 cooperate to drive the locking block 14 to rotate in the forward direction. Then the locking block 14 drives the locking wheel 21, which is mounted on one side, to rotate in the forward direction. Then the locking wheel 21 will move out from between the two round blocks 20 and drive the locking block 14 to slide outward along the limiting block 26 and the limiting groove 27. Then the locking block 14 will drive the linkage spring 15 to stretch. At the same time, the adjusting sleeve 5 drives the control sleeve 10 to rotate through the connecting rod 33. Due to the limiting of the adjusting rod 8 by the slide rail 30 and the slide groove 31, the adjusting rod 8 and the control rod 9 cannot rotate. At the same time, since the control sleeve 10 is threaded and movably sleeved on the outside of the control rod 9, the control rod 9 will drive the adjusting rod 8 to move along the slide rail 30 and the slide groove 31 in the adjusting sleeve 6. The sliding inside changes the number of adjustment holes 7 on the side wall of the regulating sleeve 6, thus changing the flow area and adjusting the conveying speed and pressure. After proper adjustment, the regulating sleeve 5 stops rotating, and the locking block 14 drives the locking wheel 21 to rotate between the corresponding two round blocks 20. Then, the linkage spring 15 resets and pulls the locking block 14 to slide inward along the limiting block 26 and the limiting groove 27. Then, the locking block 14 drives the locking wheel 21 on one side to lock into the corresponding two round blocks 20. Then, the shift sleeve 13 is released, and the spring 25 pushes the shift sleeve 13 to slide back to its original position along the guide rail 28 and the guide groove 29. The shift sleeve 13 also drives the shift rod 16 to slide back to its original position. When the spring 25 is fully reset, the shift rod... 16 no longer limits the shift plate 17 through the shift hole 18, and then the shift spring 12 pushes the shift block 11 to rotate in the opposite direction to reset. Then the shift block 11 drives the shift hole 18 to rotate in the opposite direction to reset to a position that does not correspond to the shift rod 16 through the shift plate 17. Then the shift rod 16 supports and limits the shift sleeve 13, and the guide rail 28 and guide groove 29 cooperate to limit the shift sleeve 13, so that the shift sleeve 13 cannot slide. Then the inner wall of the shift sleeve 13 limits the outer wall of the locking wheel 21 again, so that the locking wheel 21 and the locking block 14 cannot slide outward, thereby limiting the adjustment sleeve 5, so that the adjustment sleeve 5 cannot rotate, thus ensuring the stability of the adjusted structure, and thus ensuring the stable delivery of gas.
