Description

Technical Field

[0001] The utility model relates to the technical field of control valves, in particular to a double-group intelligent control valve. Background Art

[0002] Typically, a dual-group intelligent control valve consists of two independent control groups, each of which may include a valve body, valve core, drive mechanism, and sensor. The valve body is the main component of the valve, controlling the flow of fluid. The valve core, under the action of the drive mechanism, regulates the flow and pressure of the fluid. A dual-group intelligent control valve is a valve device with advanced control functions.

[0003] Some existing dual-group intelligent control valves can be used to precisely control the flow, pressure, and temperature of various fluids, ensuring the stability and reliability of production processes. For example, in a chemical reactor, the control valve can automatically adjust the feed rate of raw materials according to the progress of the reaction, improving the reaction conversion rate and product quality. However, in actual use, if the control valve leaks, the operation must be stopped immediately. If the leak is not discovered, it can easily lead to serious safety hazards and accidents. Therefore, to address these issues, the dual-group intelligent control valve is proposed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figures 1 to 3 , the double-group intelligent control valve includes a double-group valve 1. The overall structure of the double-group valve 1 is solid, and it plays a core connection and control role in the entire double-group intelligent control valve. The double-group valve 1 is internally fixedly connected with a multi-stage pressure-reducing, wake-breaking and noise-reducing regulating valve 2. This multi-stage pressure-reducing, wake-breaking and noise-reducing regulating valve 2 can effectively reduce the fluid pressure, while breaking the wake and reducing noise, greatly improving the operating stability and quietness of the entire system. Large thrust disc springs 4 are fixedly connected on both sides of the interior of the double-group valve 1. These large thrust disc springs 4 have strong elastic thrust and can provide stable support and buffering during the operation of the system;

[0028] A shut-off valve 3 is fixedly connected to the left side of the dual valve assembly 1. This shut-off valve 3 can quickly and accurately control fluid shut-off. Its unique ball-spinning design makes operation more flexible and reliable. Elastic components for providing reaction force are located at both the upper and lower ends of the left side of the dual valve assembly 1. These elastic components include two large-thrust disc springs 5. The outer portions of the two large-thrust disc springs 5 ​​are located at the upper and lower ends of the right side of the dual valve assembly 1. These two large-thrust disc springs 5 ​​also provide a strong reaction force, further enhancing the stability and reliability of the dual valve assembly 1.

[0029] Reference Figures 2 to 3The driving part of the multi-stage pressure-reducing and wake-flow noise reduction regulating valve 2 is fixedly connected with a valve stem 6. This valve stem 6 is made of solid material and plays an important connecting role. Its length is moderate and can effectively transmit the driving force to the connecting block 8 below. The bottom of the valve stem 6 is fixedly connected with the connecting block 8. The bottom of the valve stem 6 is fixedly connected with the connecting block 8. The outside of the valve stem 6 is fixedly connected with a bracket 7. This bracket 7 is made of high-strength material and has good stability and durability. Its shape is regular and can provide stable support and protection for the internal push rod 9. The inside of the bracket 7 is fixedly connected with a push rod 9. The inside of the bracket 7 is fixedly connected with a push rod 9. This push rod 9 is exquisitely designed and consists of multiple parts, which can realize the function of multi-stage adjustment. It is made of excellent material, has high strength and wear resistance, and can maintain good performance during long-term use;

[0030] The outer portion of the push rod 9 is fixedly connected to the exterior of the connecting block 8. Actuator 10 is also fixedly connected to the outer portion of the push rod 9. The drive end of the shut-off valve 3 is fixedly connected to valve stem 2 13. This valve stem 2 13 is also made of sturdy material and transmits the driving force to the external actuator bracket 14 and actuator 2 15. The outer portion of valve stem 2 13 is fixedly connected to the actuator bracket 14. This actuator bracket 14 is neatly shaped and protects valve stem 2 13 and other components within. Made of high-quality material, it offers high strength and corrosion resistance. Valve stem 2 13 is also fixedly connected to actuator 2 15, which in turn is fixedly connected to the outer portion of valve stem 2 13. This actuator 2 15 works in conjunction with other components to control the opening and closing of the shut-off valve 3. Its rational design ensures valve sealing and reliability. Connecting rods 11 are fixedly connected to the left and right sides of actuator 10. These connecting rods 11 are sturdy and of appropriate length, connecting actuator 10 to the external pull ring 12. The outside of the connecting rod 11 is fixedly connected with a pull ring 12, and this pull ring 12 shape is convenient to grasp, can easily carry out operation and maintenance. Its material is firm, can withstand larger pulling force.

[0031] Working principle: When the system starts, the dual valve group 1 reduces the pressure of the fluid through the multi-stage pressure-reducing, tail-flow-breaking and noise-reducing regulating valve 2, effectively reducing the fluid pressure and noise, ensuring that the fluid flows downstream in a stable state. The shut-off valve 3 responds quickly when needed, and realizes the shut-off control of the fluid through the action of the valve stem 13 to ensure accurate flow management of the fluid. To solve the problem of alternating high and low temperatures, when the valve body expands and contracts due to heat and cold, the metal material begins to strain, causing valve leakage. The valve seat of this valve is an independent part, supported by a large thrust disc spring to overcome the strain caused by high and low temperatures; the dual-resistance function control valve consists of two valves, the shut-off valve 3 and the multi-stage pressure-reducing, tail-flow-breaking and noise-reducing regulating valve 2. The multi-stage pressure-reducing, tail-flow-breaking and noise-reducing regulating valve 2 performs normal switching and regulation; the shut-off valve 3 is fully open for standby and automatically switches in case of failure. The above two valve groups can automatically switch in case of DCS failure;

[0032] During operation, large-thrust disc spring 1 4 and large-thrust disc spring 2 5 provide the necessary support and cushioning to enhance the stability of the system. Valve stem 1 6 transmits the driving force to the connecting block 8, which in turn drives the push rod 9 to perform multi-stage adjustment to adapt to different fluid requirements. The bracket 7 provides stable support for the push rod 9 to ensure that it maintains good performance during the adjustment process. When adjustments are required, the user can easily operate through the pull ring 12 to adjust the open or closed state of the valve, ensuring the flexibility and reliability of the system. Throughout the process, actuator 10 and actuator bracket 14 protect the internal components to prevent them from being affected by the external environment, ensuring that the dual-group intelligent control valve can operate reliably under various working conditions.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
