Technical Field

[0001] This utility model relates to the field of plastic-coated steel pipe technology, and in particular to an anti-corrosion plastic-coated steel pipe structure. Background Technology

[0002] Plastic-coated steel pipe, also known as plastic-coated pipe, steel-plastic composite pipe, or plastic-coated composite steel pipe, is a steel-plastic composite steel pipe with a steel pipe as the base material. A layer of plastic anti-corrosion coating is fused to the inner surface of the steel pipe (base pipe) or to both the inner and outer surfaces through spraying, rolling, dipping, or suction processes. Plastic-coated steel pipe has excellent corrosion resistance and relatively low frictional resistance. Most common plastic-coated steel pipes are made of steel, and their structural strength is inherently high.

[0003] An existing patent (publication number: CN221922085U) discloses a corrosion-resistant plastic-coated steel pipe structure, relating to the field of plastic-coated steel pipe technology. It includes a stainless steel pipe, a ceramic coating on the inner wall of the stainless steel pipe, and a galvanized layer on the outer wall of the stainless steel pipe. Two stainless steel pipes are used, and their opposite ends are connected to horizontal connecting pipes via flanges. One horizontal connecting pipe has a pair of regulating valves, and two longitudinal connecting pipes are fixedly connected to the two horizontal connecting pipes. In the process of implementing this solution, the inventors discovered the following problems in the existing technology that have not been adequately addressed: the filter element cannot be replaced during use and must be disassembled before replacement, affecting its use; replacing the filter element requires disassembly, which is time-consuming.

Two first support frames and second support frames are fixedly installed on the top surface of the fixing base. The first corrosion-resistant plastic-coated steel pipe and the second corrosion-resistant plastic-coated steel pipe are respectively fixedly and through-installed on the two first support frames. Clamping plates are rotatably installed on both second support frames. The second pipe and the first pipe are slidably inserted through the clamping plates. Sliding connecting pipes are fixedly installed at adjacent ends of the first corrosion-resistant plastic-coated steel pipe and the second corrosion-resistant plastic-coated steel pipe. The two sliding connecting pipes overlap with the surfaces of the corresponding clamping plates.

[0007] Preferably, a sealing gasket is installed between each of the two sliding connecting tubes and the corresponding clamping plate.

[0008] Preferably, a filter element is placed inside both the first pipe and the second pipe, a first isolation net is installed at one end of both the first pipe and the second pipe, and a second isolation net is threadedly installed inside the remaining end of both the first pipe and the second pipe, with a plurality of protrusions inside each of the two second isolation nets.

[0009] Preferably, a limit ring is fixedly installed on each of the clamping plates near the two openings.

[0010] Preferably, several gas springs are fixedly installed between the two clamping plates.

[0011] Preferably, a fixing plate is fixedly installed between the second pipe and the outer surface of the gas spring, and a prying pipe is embedded in the fixing plate.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-5 As shown, a corrosion-resistant plastic-coated steel pipe structure includes a first corrosion-resistant plastic-coated steel pipe 1, a fixing base 2, and a second corrosion-resistant plastic-coated steel pipe 3. Two first support frames 10 and second support frames 11 are fixedly installed on the top surface of the fixing base 2. The first corrosion-resistant plastic-coated steel pipe 1 and the second corrosion-resistant plastic-coated steel pipe 3 are respectively fixedly and through-installed on the two first support frames 10. Clamping plates 4 are rotatably installed on both second support frames 11. A second pipe 6 and a first pipe 5 are slidably installed through both clamping plates 4. Sliding connecting pipes 14 are fixedly installed at adjacent ends of the first corrosion-resistant plastic-coated steel pipe 1 and the second corrosion-resistant plastic-coated steel pipe 3. Both sliding connecting pipes 14 overlap with the surface of the corresponding clamping plate 4.

[0023] In this embodiment, sealing gaskets are installed between the two sliding connecting pipes 14 and the corresponding clamping plates 4; filter elements 12 are placed inside the first pipe 5 and the second pipe 6; a first isolation net 9 is installed at one end of the first pipe 5 and the second pipe 6; a second isolation net 13 is threadedly installed at the remaining end of the first pipe 5 and the second pipe 6; and several protrusions 131 are provided inside the two second isolation nets 13.

[0024] Specifically, by setting several gas springs 7 to press against the clamping plates 4 on both sides, the two clamping plates 4 abut against the corresponding sliding connecting pipes 14, which facilitates the sealing connection between the sliding connecting pipes 14 and the clamping plates 4. When it is necessary to switch the first pipe 5 and the second pipe 6, an external pry bar is inserted into the prying pipe 81, and the first pipe 5 and the second pipe 6 are rotated to switch, so as to realize the switching of the filter element 12 in the first pipe 5 and the second pipe 6. The operation is convenient and the switching is fast.

[0025] In this embodiment, a limit ring 15 is fixedly installed near the two openings of any clamping plate 4; a number of gas springs 7 are fixedly installed between the two clamping plates 4; a fixing plate 8 is fixedly installed between the second pipe 6 and the outer surface of the gas spring 7, and a prying pipe 81 is embedded in the fixing plate 8.

[0026] Specifically, when the filter element 12 needs to be maintained and replaced, the external tool can be used to rotate the protrusion 131 to remove the second isolation net 13, take out the used filter element 12, and replace it with a new filter element 12, making maintenance convenient.

[0027] Working principle: In this utility model, sealing components are installed on the outer surfaces of both ends of the first pipe 5 and the second pipe 6. The connection between the first pipe 5, the second pipe 6 and the clamping plate 4 is sealed. The thickness of the clamping plate 4 is sufficient for the first pipe 5 and the second pipe 6 to slide within it. A sealing component is provided between the sliding connecting pipe 14 and the surface of the clamping plate 4. By setting several gas springs 7 to push the clamping plate 4 to both sides, the two clamping plates 4 abut against the corresponding sliding connecting pipe 14, which facilitates the sealing connection between the sliding connecting pipe 14 and the clamping plate 4. When it is necessary to switch the first pipe 5 and the second pipe 6, an external pry tool is inserted into the prying pipe 81, and the first pipe 5 and the second pipe 6 are rotated to switch, so as to realize the switching of the filter element 12 in the first pipe 5 and the second pipe 6. The operation is convenient and the switching is fast. When it is necessary to maintain and replace the filter element 12, the external tool rotates the protrusion 131 to remove the second isolation net 13, take out the used filter element 12, and replace it with a new filter element 12. The maintenance is convenient.
