Technical Field

[0001] The utility model belongs to the technical field of heating pipelines, and particularly relates to an anti-corrosion device for heating transmission pipelines. Background Art

[0002] When winter comes, the temperature is often relatively low, making it difficult for people to work normally. It is necessary to heat classrooms, office buildings and residential buildings to slow down the invasion of the cold winter on people and enable people to work better. The main heating method is heating pipe heating.

[0003] The main way of heating is through heating pipes. Most of the heating pipes now do not have insulation and anti-corrosion devices on their surfaces. When the pipes are buried underground, corrosion is prone to occur. Therefore, an anti-corrosion device for heating transmission pipes is needed to solve the above problems. Utility Model Content

The rubber pad, the sealing strip arranged in the second sealing groove, and the first sealing groove cooperate with each other to further block the external liquid, so that the outside of the pipeline body can be doubly anti-corroded, and the inside of the pipeline body can be single-layer anti-corrosion, so that the heating transmission pipeline buried in the ground is not prone to corrosion during use, thereby ensuring the normal service life of the pipeline body.

[0008] As a preferred solution, the first anti-corrosion layer is set as a polyethylene coating, and the second anti-corrosion layer is set as a rubber ring.

[0010] By providing a first protective tube, a second protective tube and a connecting block, the first protective tube and the second protective tube connected together by rotating the connecting block cooperate with each other to conveniently fix the anti-corrosion pipeline inside it. The rotating first protective tube can drive several through holes to be precisely aligned with several through holes in the second protective tube, and then the bolts can be smoothly inserted into the corresponding two through holes, which is convenient to operate.

[0011] As a preferred solution, a fixing component is provided in the through hole.

[0012] As a preferred solution, the fixing assembly includes a bolt and a nut, the bolt is inserted into two aligned through holes, the nut is threadedly connected to the outside of the bolt, and the bolt and nut are overlapped with the first protective tube and the second protective tube respectively.

[0014] By providing the sealing strip, when the sealing strip connected to the first sealing groove moves into the second sealing groove, the sealing strip can seal the gap between one side of the first protection tube and the second protection tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model has a first anti-corrosion layer that can block the corrosive liquid inside the pipe body, and a second anti-corrosion layer that can preliminarily block the liquid outside the pipe body. The rubber pad, the sealing strip provided in the second sealing groove, and the first sealing groove cooperate with each other to further block the external liquid, so that the outside of the pipe body can be double-corroded, and the inside of the pipe body can be single-corroded, so that the heat supply pipeline buried in the ground is not easily corroded during use, thereby ensuring the normal service life of the pipe body.

[0017] The utility model is provided with a first protective tube, a second protective tube and a connecting block. The first protective tube and the second protective tube that are rotatably connected together by the connecting block cooperate with each other to conveniently fix the anti-corrosion pipeline inside it.

[0025] See also Figure 1-4 The utility model provides an anti-corrosion device for a heat supply pipeline, including an anti-corrosion component 1 and an anti-corrosion pipeline 2. The anti-corrosion component 1 includes a first protective tube 11 and a second protective tube 12. The first protective tube 11 is connected to a rotating block 13. The rotating block 13 is hinged to the second protective tube 12 through a pin. A first sealing groove 14 and a second sealing groove 15 are respectively opened on the adjacent sides of the first protective tube 11 and the second protective tube 12. A sealing strip 16 is connected in the first sealing groove 14. The sealing strip 16 is overlapped in the second sealing groove 15. The first protective tube 11 and the second protective tube 12 are connected with the same rubber pad 17. By providing the sealing strip 16, when the sealing strip 16 connected in the first sealing groove 14 moves into the second sealing groove 15, the sealing strip 16 can seal the gap on one side of the first protective tube 11 and the second protective tube 12.

[0026] The anti-corrosion pipe 2 includes a pipe body 21, and a first anti-corrosion layer 22 is connected to the outside of the pipe body 21. The first anti-corrosion layer 22 overlaps the inner wall of the rubber pad 17. By providing the rubber pad 17, when the two ends of the rubber pad 17 are in contact, the rubber pad 17 can seal the gap between the first protection pipe 11 and the other side of the second protection pipe 12;

[0027] A second anti-corrosion layer 23 is connected to the pipeline main body 21, the first anti-corrosion layer 22 is set as a polyethylene coating, and the second anti-corrosion layer 23 is set as a rubber ring. Several through holes 18 are opened in the first protective tube 11 and the second protective tube 12, and a fixing component 3 is provided in the through hole 18.
