Description

Technical Field

[0001] The utility model belongs to the technical field of finished oil pipeline valve protection sleeves, in particular to a finished oil pipeline valve protection sleeve. Background Art

[0002] Lubricating oil needs to be added to the daily operation of the oil depot gate valve to ensure the flexible opening and closing of the valve. However, the lubricating oil has a certain viscosity and is more likely to absorb sand and dust. It is easy to cause the valve stem to be scratched during maintenance, which will cause the valve to seep in and get stuck over time, and cause oil cross-linking and leakage. There are certain safety hazards. Therefore, in order to avoid the risk of exposed valve stems in the prior art, manufacturers have made metal sleeves for the valve stems, and observation slits are opened on both sides of the metal sleeves to observe the opening and closing of the valves.

[0003] The existing protection sleeves for valves in finished oil pipelines have the following shortcomings: the observation slits on both sides of the metal sleeve can be used to observe the opening and closing of the valves. However, this design makes it easier for impurities such as sand and dust to accumulate at the observation slits. Moreover, it is difficult to clearly grasp the opening and closing status of the valves when observing through remote monitoring. Moreover, in actual operation, the metal sleeve must be removed to observe the opening and closing status of the valves. At the same time, the original metal sleeve will peel off, rust, and other undesirable conditions after being exposed to wind and sun for a long time. In this case, if the metal sleeve is not removed, the valve will be damaged. The protective cover is not conducive to observing the opening and closing status of the valve. Once the protective cover is removed, sand, dust, etc. can easily enter the valve cavity through the gap of the valve disc, which can cause the valve to not close tightly and cause internal leakage. In addition, when removing the installed metal valve stem protective cover, the possibility of metal objects colliding with each other and generating sparks is increased, which undoubtedly poses certain safety hazards. In addition, the distance between the inner wall of the metal protective cover and the valve stem is relatively close, which makes it easy to stick to the lubricating oil, and the subsequent cleaning work is extremely inconvenient, which will also have a negative impact on the overall image of the site.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figures 1 to 5 shown, the present utility model provides a protection sleeve for a refined oil pipeline valve, including a butterfly valve body 1 and a protection structure 2 assembled above and in the middle of the butterfly valve body 1;

[0021] The butterfly valve body 1 includes a valve core 11, a handwheel 12, a screw rod 13 fixedly connected through the handwheel 12 and the valve core 11, and a mounting base 14 assembled outside the screw rod 13;

[0022] The protection structure 2 includes a screw rod protection sleeve 21 threadedly connected to the outer wall of the mounting base 14, and a protective cover 22 sleeved outside the valve core 11 and located below the handwheel 12.

[0023] Adopting the above solution: Through the design of the protection structure 2, the protective cover 22 can be reasonably arranged outside the valve core 11. In this way, the damage caused by the erosion of sand, rain, dust, etc. to the butterfly valve can be significantly reduced. Moreover, this protection sleeve 21 replaces the traditional metal sleeve, so that the opening and closing state of the valve can be observed very intuitively, which greatly reduces the erosion degree of sand, dust and rain on the valve stem of the valve. At the same time, the valve stem part can always remain as clean as new for a long time, which not only effectively improves the overall image of the oil depot, but also greatly extends the service life of the equipment. Not only that, the inner wall of the protection sleeve 21 and the outer wall of the screw rod 13 avoid direct contact, thus effectively avoiding the possibility of generating sparks due to the collision between metals when the valve is opened, thereby effectively ensuring safe production.

[0024] As Figures 1 to 5 shown, an A-threaded groove 141 is provided on the outer wall of the mounting base 14, and a B-threaded groove 211 adapted to the A-threaded groove 141 is provided on the inner wall of the protection sleeve 21.

[0025] Adopting the above solution: In the actual operation process, when it is necessary to install the protection sleeve 21 on the mounting base 14, only need to align the B-threaded groove 211 of the protection sleeve 21 with the A-threaded groove 141 of the mounting base 14, and then through operations such as rotation, the tight connection between the two can be easily achieved, and this connection has good stability and reliability.

[0026] As Figures 1 to 5 shown, a cavity is provided on the inner wall of the protective sleeve 21, and there is a gap between it and the outer wall of the screw 13. The vertically upward length of the protective sleeve 21 is greater than the length of the screw 13.

[0027] With the above solution: The gap between the protective sleeve and the outer wall of the screw 13 can effectively avoid direct friction and collision between the two, reduce wear and energy loss, and extend the service life of related components. Moreover, this gap can also provide a certain buffer space for physical phenomena such as thermal expansion and contraction that may occur, ensuring that the entire device can maintain a good operating state under different temperature and working conditions. The length of the protective sleeve 21 is greater than the length of the screw 13, which enables the protective sleeve 21 to effectively protect and cover the screw 13 within a larger range, and can play a more excellent protective effect both in preventing the intrusion of external debris and in resisting the influence of various environmental factors.

[0028] As Figures 1 to 5 shown, both the protective sleeve 21 and the protective cover 22 are made of acrylic material. The protective sleeve 21 is located above the protective cover 22. The protective cover 22 is of a hollow type and the inner wall of the protective cover 22 does not contact the outer wall of the valve core 11.

[0029] With the above solution: The protective sleeve 21 and the protective cover 22 form a complete protection structure 2. Acrylic is a plastic material as transparent as glass, with high transparency for easy observation of the valve opening height; it has good wear resistance and stability, and can better adapt to the erosion in the open-air environment and high-temperature weather; it is resistant to corrosion by a variety of chemicals and can better resist the corrosion of oil products; it has flame retardancy to avoid the risk of combustion, with a smooth surface, easy to clean and maintain. This enables the intuitive observation of the valve opening and closing state without removing the valve stem protective sleeve when operating the valve, greatly reducing the erosion of sand, dust, and rain on the valve stem of the valve, making the valve stem part remain smooth and new for a long time, improving the image of the oil depot, and extending the service life of the equipment.

[0030] The working principle and usage process of the present utility model:

[0031] First, before installation, the installation base 14 is polished to remove rust, its surface is polished as flat as possible, sprayed with rust inhibitor for anti-corrosion, and then painted. Then, the B-thread groove 211 of the protective sleeve 21 is aligned with the A-thread groove 141 of the installation base 14, and through operations such as rotation, the tight connection between the two can be easily achieved. Subsequently, the protective cover 22 is sleeved outside the valve core 11 and below the handwheel 12, so as to significantly reduce the damage caused by the erosion of sand, rain, and dust to the butterfly valve.
