Description

Technical Field

[0001] This utility model relates to the field of valve stem packing technology, specifically a valve stem packing compaction device. Background Technology

[0002] A packing material is required for sealing between the valve stem and the valve body. The packing material is mainly packing. A packing sleeve is fitted between the packing and the valve stem. The packing sleeve is responsible for connecting the valve body and forming a seal between them. The packing is filled between the packing sleeve and the valve stem to seal the valve stem and prevent liquid leakage from the valve body when the valve stem rotates. The packing is a consumable item, so it needs to be replaced after oil leakage occurs. When installing a new packing, the traditional installation method is to manually tighten the packing with a push rod. This operation method results in uneven stress on the packing, which can cause deformation and partial incomplete tightening, increasing the possibility of leakage later.

[0003] In the prior art, such as the technical field involved in the patent with publication number CN207915376U, valve stem packing compaction devices are one of the important equipment. However, traditional valve stem packing compaction devices have some shortcomings, such as limited adjustment accuracy of the clamping mechanism, need to improve the stability of the support structure, easy loosening of connecting parts, and insufficient protective effect of protective parts. In order to solve these problems, this embodiment proposes an improved valve stem 2 packing compaction device 1. By adopting a lever-type clamping mechanism, a base and bracket with stable support, bolts and nuts for fastening, a screw structure that can be manually and automatically adjusted, and a cover and guard plate with protective function, the performance and reliability of the device are effectively improved. Therefore, we propose a valve stem packing compaction device. Utility Model Content

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Example 1, please refer to the appendix. Figure 1 -Appendix Figure 4 The valve stem 2 packing compaction device 1 includes a compaction device 1, which includes a valve stem 2, packing, a packing gland 4, a clamping mechanism 5, a sealing gasket 6, a support structure 7, a connecting component 8, an adjusting device 9, and a protective component 10. The valve stem 2 is used to connect to the valve. The packing is arranged around the valve stem 2. The packing gland 4 is used to compact the packing. The clamping mechanism 5 is connected to the packing gland 4 and is used to provide clamping force. The sealing gasket 6 is arranged between the packing gland 4 and the valve stem 2. The support structure 7 is used to support the entire device. The connecting component 8 is used to connect the various components. The adjusting device 9 is used to adjust the magnitude of the clamping force. The protective component 10 is used to protect the device.

[0023] In this embodiment, the clamping mechanism 5 includes a lever-type clamping component for adjusting the tightness of the packing gland 4;

[0024] This lever-type clamping component, through its ingenious mechanical structure design, can effectively transmit the force applied to one end to the other, thereby achieving precise adjustment of the packing gland tightness.

[0025] Specifically, when it is necessary to increase the tightness of the packing gland 4, the operator can operate one end of the lever to amplify the force using the lever principle, thereby making the packing gland 4 press more tightly onto the packing to ensure the sealing effect of the packing. At the same time, during the adjustment process, the operator can flexibly control the tightness according to actual needs to achieve the best compaction effect.

[0026] In this embodiment, the support structure 7 includes a base and a bracket that provide stable support.

[0027] The base is made of sturdy and durable materials, providing a solid foundation and stable support for the entire device. The bracket is connected to the base and has a reasonable structural design that can effectively distribute the weight of the device and ensure its stability during operation.

[0028] In practice, the base is usually installed in a suitable location in the workplace to ensure that the device does not shake or tilt during use, while the bracket is designed and installed according to the structure and layout of the device to provide all-round support so that the device can operate stably in various working environments.

[0029] In this embodiment, the connecting component 8 includes bolts and nuts for fastening;

[0030] These bolts and nuts are made of high-quality materials, have high strength and good corrosion resistance, and can ensure a reliable connection during long-term use;

[0031] During the assembly of the device, the operator will pass the bolts through the corresponding components as needed and tighten them with nuts. By controlling the tightening torque appropriately, the connection between the components can be ensured to be firm and reliable, and there will be no loosening or falling off. At the same time, when it is necessary to disassemble or maintain the device, the nuts can be loosened to separate the components.

[0032] Specifically, the organic combination of valve stem 2, packing, packing gland 4, clamping mechanism 5, sealing gasket 6, support structure 7, connecting parts 8, adjusting device 9, and protective parts 10 achieves effective packing compaction. Among them, the clamping mechanism 5 of the compaction device 1 adopts a lever design, which can more accurately adjust the tightness of the packing gland 4, ensuring that the packing compaction effect meets the requirements and improving the stability and reliability of the device.

[0033] Example 2, please refer to the appendix. Figure 1 - Appendix Figure 4The valve stem 2 packing compaction device 1 includes a compaction device 1, which includes a valve stem 2, packing, a packing gland 4, a clamping mechanism 5, a sealing gasket 6, a support structure 7, a connecting component 8, an adjusting device 9, and a protective component 10.

The clamping mechanism 5 is connected to the packing gland 4 and is used to provide clamping force. The sealing gasket 6 is arranged between the packing gland 4 and the valve stem 2. The support structure 7 is used to support the entire device. The connecting component 8 is used to connect the various components. The adjusting device 9 is used to adjust the magnitude of the clamping force. The protective component 10 is used to protect the device.

[0034] In this embodiment, the adjusting device 9 includes a screw structure that can be adjusted manually and automatically;

[0035] Operators can rotate the adjustment knob to move the screw through the threaded component, thereby achieving fine adjustment of the clamping force. This manual adjustment method is simple to operate and allows users to accurately adjust the tightness of the packing gland 4 according to actual needs.

[0036] The automatically adjusting screw structure is equipped with an intelligent control system and a drive motor. Through a preset program or external commands, the drive motor can drive the screw to rotate automatically, achieving precise adjustment of the clamping force. This automatic adjustment method not only improves work efficiency but also ensures the accuracy and consistency of the adjustment.

[0037] In this embodiment, the protective component 10 includes a cover and a protective plate with protective functions;

[0038] The enclosure is made of high-strength, wear-resistant materials, effectively covering and protecting critical parts of the device from external damage. The enclosure's design fully considers the device's shape and structure, ensuring that its installation will not affect the device's normal operation.

[0039] Protective plates are installed in vulnerable areas of the device, such as edges and corners. The materials used for these plates have excellent impact resistance and protective properties, acting as a buffer and protector in the event of accidental collisions or impacts, reducing the risk of damage to the device.

[0040] In practice, the cover and protective plate are fixed to the device by fasteners or clips, ensuring a secure and reliable installation that provides comprehensive protection for the device.

[0041] Specifically, the base and bracket of the support structure 7 provide stable support, providing a solid support for the entire device, making it less prone to shaking or deformation during operation, thereby extending the service life of the device and improving work efficiency. The connecting parts 8 use fastening bolts and nuts to ensure that the connection between the various parts is firm and reliable, and is not prone to loosening, thus ensuring the normal operation of the device.

[0042] Working principle:

[0043] First, the compaction device 1 is installed in the designated position, and the various components are connected and fixed by the connecting parts 8. Then, the valve stem 2 is connected to the valve, and packing is placed around the valve stem 2. The operator can adjust the clamping force by selecting manual or automatic adjustment mode through the adjusting device 9 as needed. The clamping mechanism 5 uses the lever principle or intelligent control system and drive motor to transmit the applied force to the packing gland 4, so that it clamps the packing. The sealing gasket 6 plays a sealing role to prevent media leakage. The base and bracket of the support structure 7 provide stable support for the device. The cover and guard plate of the protective component 10 protect the device from external damage. During operation, the clamping force and other parameters can be adjusted at any time according to the actual situation to ensure the compaction effect and normal operation of the device.
