Description

Technical Field

[0001] This utility model relates to the field of back pressure device technology, and in particular to a back pressure valve adjustment support device. Background Technology

[0002] Back pressure valve regulating support devices are key auxiliary equipment in petrochemical plants, long-distance pipeline systems, and industrial fluid control. They provide precise positioning and dynamic load-bearing for the valve body through mechanical structures, and must maintain structural stability and regulating response capabilities under high temperature and high pressure conditions. Existing back pressure valve supports mostly adopt integrated designs with welded bases or separate bolt-fixed structures. During valve maintenance or changes in operating parameters, the traditional rigid fixing mode requires the use of lifting equipment to complete the overall displacement. During adjustment, torque imbalance can easily cause valve stem deformation, and fatigue cracks are prone to occur at the welded joints in pipeline thermal expansion and contraction scenarios.

[0003] Existing technologies have significant shortcomings, including the lack of modular positioning components in the support structure (such as the graded limiting interface between the embedded ring and the nested seat), the reliance on on-site welding for conventional flange connections limiting the compatibility between the valve body and the support frame, and the absence of a manual screw-based lifting mechanism for height adjustment without a coordinated guiding mechanism of protective side plates and limiting plates. This makes axial deflection during adjustment prone to occur (offsets can reach ±5°), threatening the safety of the valve seat sealing surface. Furthermore, the transmission components lack a rigid connection design between the motor drive and the mechanical lifting rod, making it difficult to simultaneously meet the 0.1mm accuracy requirement and the 1-ton load-bearing capacity requirement in manual adjustment mode. Therefore, we provide a back pressure valve adjustment support device. Utility Model Content

[0026] Example 1

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a back pressure valve adjustment support device, including: a sleeve mechanism 1, the sleeve mechanism 1 including a base 11, a mounting column 12 provided on the base 11, a nested seat 13 provided on the outer surface of the mounting column 12, a snap-fit ​​sleeve 14 provided on the nested seat 13, an inner ring 15 provided in the nested seat 13, a back pressure valve body 16 provided in the inner ring 15, and an adjustment mechanism 2 provided at the bottom of the base 11;

[0028] The adjustment mechanism 2 includes a connecting frame 21, an adjustment seat 22 is provided between the two connecting frames 21, a lifting rod 23 is provided in the adjustment seat 22, a limit plate 24 is provided at one end of the lifting rod 23, a protective side plate 25 is provided on both sides of the limit plate 24, a motor seat 27 is provided at one end of the protective side plate 25, a mounting frame 26 is provided on the motor seat 27, and a transmission rod 28 is provided in the motor seat 27.

[0029] One end of the mounting post 12 is welded to the base 11. The outer surface of the mounting post 12 is nested in the nested seat 13. One side of the snap-fit ​​sleeve 14 is nested and snapped into the nested seat 13. The outer surface of the inner ring 15 is nested in the nested seat 13. The outer surface of the back pressure valve body 16 is nested in the inner ring 15. The bottom of the base 11 is fixed to the connecting frame 21. One side of the two connecting frames 21 is nested in the outer surface of the adjusting seat 22.

[0030] The adjusting seat 22 is limited to the outer surface of the lifting rod 23 for lifting and adjusting. One side of the limiting plate 24 is fixedly connected to one end of the lifting rod 23. The motor seat 27 is connected to the end of the lifting rod 23 away from the limiting plate 24. The two ends of the protective side plate 25 are respectively connected between the limiting plate 24 and the motor seat 27. One end of the mounting frame 26 is welded to the motor seat 27. The transmission rod 28 is nested in the motor seat 27.

[0031] In this embodiment, when the operator uses this support device to support the back pressure valve, the operator can place the back pressure valve body 16 to be supported in the embedded ring 15. The outer surface of the embedded ring 15 is nested in the nesting seat 13 and is connected and fixed to the connecting frame 21 by using the mounting post 12 and the snap-fit ​​sleeve 14. One end of each of the two connecting frames 21 is welded to both sides of the adjusting seat 22. In this way, the operator can adjust the adjusting seat 22 on the lifting rod 23. The limiting plate 24 can limit the top of the adjusting seat 22 on the lifting rod 23. The protective side plate 25 can effectively prevent the angle deviation during the rising process. The two ends of the transmission rod 28 are respectively connected between the lifting rod 23 and the motor seat 27 for lifting transmission adjustment, thereby improving its practicality in actual use.

[0032] Working principle:

[0033] like Figure 1-4 As shown, when the operator uses this support device to support the back pressure valve, firstly, the operator places the back pressure valve body 16 to be supported into the inner ring 15, ensuring that the back pressure valve can be stably embedded and fixed within the inner ring 15. Subsequently, the outer surface of the inner ring 15 fits tightly with the inner surface of the nested seat 13, firmly nesting the inner ring 15 within the nested seat 13, providing basic support for the subsequent support structure.

[0034] Next, the workers use the mounting post 12 and the snap-fit ​​sleeve 14 to connect and fix the embedded ring 15 to the connecting frame 21, ensuring the stability of the entire support system. The two ends of the connecting frame 21 are fixed to both sides of the adjusting seat 22 by welding, providing a solid support foundation for the adjusting seat 22. Through the adjusting seat 22, the workers can adjust the lifting rod 23, thereby achieving precise control of the position of the back pressure valve body 16.

[0035] To ensure accuracy during adjustment, a limiting plate 24 is positioned on top of the adjusting seat 22, limiting its vertical movement on the lifting rod 23 and preventing it from exceeding the predetermined position. This allows operators to effectively control the adjustment range, ensuring the safety and stability of the support device.

[0036] Furthermore, the design of the protective side plate 25 effectively prevents the adjusting seat 22 from shifting at an angle during its ascent, ensuring that the back pressure valve body 16 maintains a stable posture within the support device. The protective side plate 25 not only provides physical protection but also enhances the safety of the support device, preventing equipment damage or operational difficulties caused by angular shifts.

[0037] To achieve precise lifting and lowering adjustment, the two ends of the transmission rod 28 are connected to the lifting rod 23 and the motor base 27, respectively. The motor drives the transmission rod 28 to perform lifting and lowering transmission adjustment. The motor base 27 drives the movement of the transmission rod 28, thereby driving the lifting rod 23 to move up and down, and precisely controlling the position change of the back pressure valve body 16.

[0038] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0039] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
