Description

Technical Field

[0001] This utility model relates to the field of fluid control technology, and in particular to an automatic regulating valve needle device. Background Technology

[0002] A valve needle device is a component installed inside a valve that controls the size of the fluid passage by changing its own position. Automatically adjustable valve needle devices are essential because operating conditions are constantly changing in various fluid transmission and application scenarios, making timely and precise manual adjustments difficult. Automatically adjustable valve needle devices can adjust fluid flow rate, pressure, and direction in real time based on preset parameters or sensor feedback, maintaining stable equipment operation and preventing equipment failures and reduced production efficiency caused by fluctuations in fluid parameters. This ensures automated, efficient, and safe production processes in fields such as petrochemicals, power generation, and HVAC.

[0003] The working principle of the automatic regulating valve needle device is as follows: the sensor monitors the relevant parameters of the fluid in real time and transmits these parameter signals to the controller. The controller compares and calculates the received signals with the preset target values, and then sends a command to the actuator based on the calculation results. The actuator drives the valve needle to move accordingly, thereby changing the flow area between the valve needle and the valve seat, so as to accurately regulate the fluid flow rate, pressure and other parameters, so that the fluid components can operate stably and efficiently.

[0004] In existing technologies, some regulating valve needle devices are fixed to pipelines using bolts. During installation, manual tightening of bolts is required, which is cumbersome, time-consuming, and inefficient. When the installation space is limited or the location is special, operation is inconvenient and installation is more difficult. Therefore, an automatic regulating valve needle device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic adjusting valve needle device, which aims to improve the existing technology that uses bolts to fix it. During installation, it is necessary to manually tighten the bolts, which is a cumbersome and time-consuming process with low installation efficiency. When the installation space is limited or the location is special, it is inconvenient to operate and increases the difficulty of installation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic regulating valve needle device includes a base shell, with fixed tubes fixedly connected to both the left and right sides of the base shell, a connecting tube fixedly connected to the outside of the fixed tubes, a through tube fixedly connected to the inner wall of the connecting tubes, protective shells fixedly connected to both the front and rear sides of the through tubes, a movable plate slidably connected to the inner wall of the protective shells, a force-applying block fixedly connected to the rear side of the movable plate, connecting plates fixedly connected to both the left and right sides of the movable plate, and a sealing component fixedly connected to the inner wall of the fixed tubes for sealing.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the through pipe drives the force-applying block into the connecting pipe. When the force-applying block moves to the limit of the groove of the connecting pipe, the through pipe is rotated to compress the force-applying block and pressurize the spring.

[0032] Reference Figure 2 and Figure 3 One embodiment of this utility model is an automatic regulating valve needle device, which includes a bottom shell 1, which protects the internal valve tube. Fixed pipes 2 are fixedly connected to both the left and right sides of the bottom shell 1. The fixed pipes 2 are fixed to the left and right sides of the outer shell to help the valve to flow. A connecting pipe 3 is fixedly connected to the outside of the fixed pipe 2. A through pipe 4 is fixedly connected to the inner wall of the connecting pipe 3. The connecting pipe 3 connects the fixed pipe 2 and the through pipe 4. Protective shells 5 are fixedly connected to both the front and rear sides of the through pipe 4. A movable plate 6 is slidably connected to the inner wall of the protective shell 5. A spring 7 is fixedly connected to the rear side of the movable plate 6. Connecting plates 9 are fixedly connected to both the left and right sides of the movable plate 6. A force-applying block 8 is fixedly connected to the front side of the movable plate 6. The protective shell 5 protects the internal fixed components. The movable plate 6 receives the pushing force of the force-applying block 8, thereby moving inside the protective shell 5. The connecting plate 9 moves with the movable plate 6. The force-applying block 8 receives the force inside the connecting pipe 3, thereby receiving the force. A sealing component for sealing is fixedly connected to the inner wall of the fixed pipe 2.

[0033] Reference Figure 2 and Figure 4 The sealing assembly includes a fixed ring 12, which is externally fixedly connected to the inner wall of the fixed tube 2. A spring 13 is fixedly connected to the right side of the fixed ring 12, and a static sealing ring 14 is fixedly connected to the right side of the spring 13. A dynamic sealing ring 15 is fixedly connected to the left side of the tube 4. The fixed ring 12 is fixed inside the fixed tube 2. The spring receives the pushing force of the static sealing ring 14 and thus stores the elastic force. The dynamic sealing ring 15 allows the tube 4 to move.

[0034] Reference Figures 1 to 3A sensing block 20 is fixedly connected to the front side of the bottom shell 1. The sensing block 20 senses the pressure inside the valve and thus generates a response. The rear side of the spring 7 is fixedly connected to the rear inner wall of the protective shell 5. The spring receives the pushing force of the moving plate 6 and thus moves. Guide plates 10 are fixedly connected to the left and right inner walls of the protective shell 5. The far sides of the two connecting plates 9 are slidably connected to the near sides of the two guide plates 10. The guide plates 10 receive external force and thus move. A fixing block 18 is fixedly connected to the top of the bottom shell 1. A top shell 19 is fixedly connected to the top of the fixing block 18. The fixing block 18 connects the bottom shell 1 and the top shell 19. A power block 21 is fixedly connected to the inner wall of the top shell 19. The power block 21 receives the sensing force from the sensing block 20 and thus transmits power. A force-applying rod 23 is fixedly connected to the bottom of the power block 21. The outside of the force-applying rod 23 is slidably connected to the bottom of the top shell 19. The inner wall of the valve is connected to a force-applying rod 23 which receives power from the power block 21 and moves accordingly. A valve stem 22 is fixedly connected to the bottom of the force-applying rod 23. The bottom of the valve stem 22 is slidably connected to the bottom inner wall of the bottom shell 1. The valve stem 22 receives the force from the force-applying rod 23 and thus blocks the valve. A filter plate 11 is fixedly connected to the inner wall of the through pipe 4. The filter plate 11 filters out impurities inside. A semi-circular block 24 is fixedly connected to the inner wall of the through pipe 4. The semi-circular block 24 protects the protective shell 5. The right side of the static sealing ring 14 contacts the left side of the dynamic sealing ring 15. The static sealing ring 14 contacts the dynamic sealing ring 15, thus sealing it. A fixing plate 16 is fixedly connected to the outside of the dynamic sealing ring 15. A fixing plate 27 is fixedly connected to the outside of the static sealing ring 14. The fixing plate 16 applies force to the fixing plate 27, causing the fixing plate 27 to move and get stuck in the guide groove inside the fixing pipe 2.

[0035] Working principle: The operator holds the force-applying block 8 upwards, which drives the through pipe 4 into the connecting pipe 3. The force-applying block 8 moves within a groove on the inner wall of the connecting pipe 3. When the force-applying block 8 reaches the end of the groove, the connecting pipe 3 comes into contact with the fixed pipe 2. The operator then rotates the through pipe 4. The groove inside the connecting pipe 3 has inclined blocks around it, which facilitates the rotation of the force-applying block 8. After the force-applying block 8 rotates, it drives the moving plate 6 to move. The moving plate 6 drives the connecting plate 9 to move under the action of the guide plate 10, which pushes the spring and stores the elastic force, causing the force-applying block 8 to rotate to the front inner wall of the connecting pipe 3. At this point, the force-applying block 8 is engaged in the limiting groove, and the spring releases its force, thus locking the force-applying block 8 in the limiting groove. This achieves rapid installation of the pipe and valve needle device, reduces installation difficulty and labor costs, reduces reliance on professional skills during installation, and avoids potential installation errors caused by complex operations.

[0036] When the through pipe 4 moves within the connecting pipe 3, the dynamic sealing ring 15 approaches the static sealing ring 14, causing the fixing plate 16 to move along with the fixing plate 2 17. Under the action of the dynamic sealing ring 15, the static sealing ring 14 is compressed by the spring 2, thus buffering the static sealing ring 14. As the fixing plate 2 17 moves, it moves within the guide groove of the fixing pipe 2, and finally locks into the guide groove, fixing the static sealing ring 14 and buffering the dynamic and static sealing rings. This achieves the sealing of the pipe and valve needle device, ensures the sealing of the pipe components, prevents media leakage, avoids resource waste and environmental pollution, and maintains stable equipment operation.

[0037] After installation, the device is started. When a problem occurs with the valve, the sensor detects the internal issue and transmits it to the power block 21. The power block 21 then moves the force rod 23. The force rod 23 moves the valve stem 22, thereby adjusting and stabilizing the pressure.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
