Description

Technical Field

[0001] This utility model relates to the field of oil pipeline valve filtration technology, and in particular to a valve for oil pipelines with a filtration component. Background Technology

[0002] Valves for oil pipelines are key control components installed in pipeline systems during oil extraction, transportation, storage, and processing. Their core functions are to cut off the flow of oil within the pipeline, regulate the flow rate, control the pressure, or guide the flow of the medium.

[0003] Crude oil or refined oil transported in oil pipelines often contains solid impurities such as mud, metal shavings, and welding slag. These impurities can cause wear on valve sealing surfaces, valve core jamming, and even damage to internal valve components, leading to leaks or valve failure. They may also affect the operation of downstream equipment. Therefore, it is necessary to install a filter device before the valve. The filter device uses a filter with a specific pore size. When fluid flows through, the filter screen traps impurities, allowing only clean fluid that meets the requirements to pass through. At the same time, the filter has a drain port, which can be used to regularly clean the trapped impurities, ensuring that the internal structure of the valve is not corroded by impurities, maintaining the valve's sealing performance and opening and closing flexibility, and ensuring the safe and stable transportation of pipelines.

[0004] When valves and filters are combined in traditional oil pipelines, the filter structure is inconvenient to clean. Frequent cleaning increases workload and the probability of valve damage, while untimely cleaning will affect the filtration effect and increase resistance.

[0005] Therefore, it is necessary to provide a valve for oil pipelines with a filter assembly to solve the above-mentioned technical problems. Utility Model Content
