Embodiment Construction
[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] This embodiment includes an inner tube 4 and an outer tube 2, the inner tube 4 is inserted into the outer tube 2, and an annular filtered liquid chamber 3 is formed between the inner tube 4 and the outer tube 2, and the filtered liquid is The inner tube 4 corresponding to one end of the chamber 3 is provided with a filter section 1, and the inner tube 4 corresponding to the other end of the filtered liquid chamber 3 is provided with a liquid passage section 7. The inner tube 4 is slidingly sealed and inserted with two core plugs, according to the position The relationship is respectively called the filter section core plug 8 and the liquid passage section core plug 11. The two core plugs have the same structu...

The invention belongs to the field of oil pipelines, and in particular relates to a high-strength oil pipeline, which includes an inner pipe and an outer pipe, an annular filtered liquid passage chamber is formed between the inner pipe and the outer pipe, and an inner pipe corresponding to one end of the filtered liquid passage chamber There is a filter section, and the inner tube corresponding to the other end of the filtered liquid chamber is provided with a liquid section. The inner tube is slidingly sealed and inserted with two core plugs, which are respectively called the filter section core plug and the liquid section core plug according to the positional relationship. , the core plug of the filter section can completely block the filter section by moving axially, the core plug of the liquid passage section can completely block the liquid section by moving axially, the inner tube between the core plug of the filter section and the core plug of the liquid passage There is a pressure tube fixed on the top, and the pressure of the pressure tube pushes the core plug of the filter section and the core plug of the liquid passage to move backwards, and the negative pressure of the pressure pipe makes the core plug of the filter section and the core plug of the liquid passage move toward each other; Compared with the single function, the present invention has three functions of filtering, on-line flushing of the filter screen and interception, and can be switched arbitrarily and used repeatedly.
Description
technical field [0001] The invention belongs to the field of oil pipelines, in particular to a high-strength oil pipeline. Background technique [0002] The oil is pumped to the ground through the pumping unit and transported to the union station through the oil pipeline laid on the shallow surface. The existing oil pipeline is composed of many ordinary oil pipelines sealed from the end to the end, and only has the function of transportation. Very singular. Contents of the invention [0003] (1) Technical problems to be solved: [0004] In order to solve the problem of the single function of the existing oil delivery pipeline in the background technology, the present invention proposes a multifunctional high-strength oil delivery pipeline, which has three functions of filtering, online backwashing filter, and interception. [0005] (2) Technical solution: [0006] The technical solution provided by the present invention is: a high-strength oil delivery pipe, including a...
