Abstract
The utility model relates to a corrosion preventing implement for a pipeline, particularly a diameter expanding device for a thermal shrinkable pipe. The utility model has the technical proposal that both ends of a middle pipe 3 are fixedly connected with flanges 1, and the middle pipe 3 is fixedly connected with a hot fluid valve 2. Outer flange disks of the flanges 1 are connected with inner flange disks through a gradually expanding cone 4 and a plastic sealing flange 5, the thermal shrinkable pipe is fixedly connected with an outer flange disk of the plastic flange 5, and the end part of the thermal shrinkable pipe is provided with a compressible fluid valve 6. The middle pipe 3, the flanges 1 and the gradually expanding cone 4 can be made of hard metal materials, and can also be made of glass fiber reinforced plastics, plastics, nylon, wood and composite materials. The middle pipe 3 comprises a reticular soft or hard circular cylinder wall. The utility model overcomes the defects and the deficiencies of the prior art, and provides a steel pipe for the outer anticorrosion of a pipeline and a column type article. The utility model has the advantages of no rust removal, convenient anticorrosion treatment of a welding joint, low operating temperature, no pollution, reliable quality of anticorrosion, fast constructing speed, shock resistance, corrosion resistance and low cost.
Description
One, technical field:
The utility model belongs to a kind of anti-corrosion pipeline special plastic heat-shrink tube hole enlargement special-purpose machines and tools.
Two, background technology:
Pipeline corrosion protection is at present generally adopted asphalt-coating to add and is twined glass wool cloth, seriously polluted during corrosion prevention operation, antiseptic effect is undesirable, and one section cogongrass of the puddles of water particularly couchy can penetrate the pitch anticorrosive coat, make the salt buck infiltrate steel tube surface, so that pipeline is often bored a hole.Perhaps adopt yellow jacket anticorrosion, obtained effect preferably, but yellow jacket anticorrosion equipment costliness, preservative process complexity, weld seam anticorrosion be difficult to construction at the scene and expense very high.At present, cold belt is anticorrosion, and to replace pitch anticorrosion, this is outer corrosion-resistant one much progress of pipeline really, but this technology is once the weakness that occurs existing some to be difficult to overcome, and twines that implement is huge, cost is high, rust cleaning requires high, prefabricated anticorrosion site operation rapid wear to pipeline.
Three, summary of the invention:
The utility model is exactly the problems referred to above that exist at prior art, and a kind of heat-shrink tube expander of simple possible is provided.Its technical scheme is to be fixedly connected with flange 1 at the two ends of intervalve 3, on intervalve 3, be fixedly connected with hot fluid valve 2, the outward flange dish of flange 1 is connected by the inner flange of flaring cone 4 and plastic seal flange 5, heat-shrink tube is fixedlyed connected with the outward flange dish of plastics flange 5, and in its end hydraulic fluid valve 6 is installed.Intervalve 3, flange 1 and flaring cone 4 are that hard metal material is made, and also can use fiberglass, plastics, nylon, timber, synthetic material to make.Intervalve 3 comprises the cylindrical wall of netted soft or hardware.
The utility model has overcome the shortcoming and defect of prior art, a kind of steel pipe need not eliminate rust, the preservative treatment of welding line joint convenient, operating temperature is low, pollution-free, anticorrosive quality is reliable for pipeline and column type goods outer anticorrosion provides, and speed of application is fast, shock-resistant, corrosion-resistant, cost is low.
Four, description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment:
For further disclosing the technical solution of the utility model, bottom is described in detail by embodiment in conjunction with the accompanying drawings: be fixedly connected with flange 1 at the two ends of intervalve 3, on intervalve 3, be fixedly connected with hot fluid valve 2, the outward flange dish of flange 1 is connected by the inner flange of flaring cone 4 and plastic seal flange 5, heat-shrink tube is fixedlyed connected with the outward flange dish of plastics flange 5, and in its end hydraulic fluid valve 6 is installed.Intervalve 3, flange 1 and flaring cone 4 use steel body material to make usually, can certainly use fiberglass, plastics, nylon, timber, synthetic material to make.Intervalve 3 comprises the cylindrical wall of netted soft or hardware, as liner.
During use, the diameter of intervalve is greater than the diameter of heat-shrink tube, heat-shrink tube is passed intervalve after, its two ends are by plastics flange sealing and fixing.From hot fluid valve injection steam or hot water the heat-shrink tube in the intervalve is heated, pressurize in heat-shrink tube from the high-pressure fluid valve simultaneously, make the heat-shrink tube hole enlargement, finish hole enlargement to the needs size.
