[0030] like Figure 1 As shown, it is a corrosion-resistant hazardous chemical pipeline 100 shown in the present invention, which is installed at the flange 201 connection of each hazardous chemical pipeline 200 to reduce corrosion at the flange 201 connection of each hazardous chemical pipeline 200.

[0031] like Figure 1As shown, the corrosion-resistant hazardous chemical pipeline 100 includes: an outer shell 10, a sealing layer 20 and an extrusion assembly 30, wherein the number of the outer shells 10 and the sealing layer 20 are both two, and the two outer shells 10 are used to install each sealing layer 20, and each sealing layer 20 is used to fit with the flange 201 connection of the hazardous chemical pipeline 200. The extrusion assembly 30 is used to drive the two outer shells 10 to approach each other, so as to drive each outer shell 10 to extrude the sealing layer 20, so that the sealing layer 20 fits with the flange 201 connection of the hazardous chemical pipeline 200, so as to achieve corrosion-resistant treatment of the connection of the hazardous chemical pipeline 200. The extrusion assembly 30 controls the two outer shells 10 to approach each other to extrude the sealing layer 20 and fit the flange 201 connection of the hazardous chemical pipeline 200. Compared with the method of applying anti-rust oil or paint, the time of corrosion-resistant treatment of the connection of the hazardous chemical pipeline 200 can be effectively reduced, thereby reducing the overall laying time of the hazardous chemical pipeline 200 and improving the overall laying efficiency of the hazardous chemical pipeline 200.

[0032] Below, combined Figures 1 to 3 , the above-mentioned corrosion-resistant hazardous chemical pipeline 100 is further explained.

[0033] like Figures 1 to 2 As shown, each shell 10 includes a shell 11 and a flange 12. The shell 11 is connected to the sealing layer 20. The flange 12 is arranged around the shell 11. The flanges 12 of each shell 10 are spaced apart to form an extrusion space 121. In order to reduce the time for each shell 10 to cover the flange 201 connection of the hazardous chemical pipeline 200, the shell 10 also includes a pivot part 14, which is pivoted to the pivot part 14 of another shell 10. By controlling the shell 11 to rotate around the pivot part 14, the time for the two shells 10 to cover the flange 201 connection of the hazardous chemical pipeline 200 can be effectively reduced. The two sealing layers 20 are respectively installed in the shell 11 of each shell 10. Each sealing layer 20 has a sealing surface 21. When each sealing layer 20 is in contact with the hazardous chemical pipeline 200, the position of each sealing surface 21 is set corresponding to the extrusion space 121.

[0034] like Figures 1 to 2 As shown, there are multiple extrusion member groups, each of which is arranged around the sealing layer 20. Each extrusion member group includes a bow member 31, a push member 32 and a fastener 33. The bow member 31 is arranged in the extrusion space 121 and is connected to the push member 32. The push member 32 is arranged corresponding to the position of each sealing surface 21. The fastener 33 drives the shells 10 to approach each other to compress the extrusion space 121. The extrusion bow member 31 drives the push member 32 to fit the position of the corresponding sealing surface 21 of each sealing layer 20.

[0035] like Figure 3As shown, the bow member 31 includes a contact segment 311 and an arc segment 312. There are two contact segments 311. The two contact segments 311 are respectively abutted against the flange 12 of each housing 10. The arc segment 312 is connected to the push member 32. In order to improve the installation accuracy of the two contact segments 311, the housing 10 also includes a limit block 13. The limit block 13 is connected to the flange 12 and abuts against one end of the bow member 31 away from the push member 32. The push member 32 is arranged in an arc shape. The height of the push member 32 is less than the distance between the two contact segments 311 to avoid the push member 32 being abutted by the flange 12 and difficult to move when the distance between the two contact segments 311 is reduced.

[0036] like Figure 2 As shown, the fastener 33 includes a bolt 331 and a nut 332. The bolt 331 passes through each flange 12 and the contact section 311 of the bow member 31. The nut 332 is threadedly connected to the bolt 331 and drives one flange 12 to approach the other flange 12. Each contact section 311 is provided with a through hole 133 for the fastener 33 to pass through.

[0037] When the corrosion-resistant hazardous chemical pipeline 100 provided by the present application is in use: the sealing layer 20 is respectively installed in each shell 10, and the sealing layer 20 is used to cover the connection of each hazardous chemical pipeline 200, and the bow member 31 of the extrusion member group is placed in the extrusion space 121 formed between the two shells 10. By controlling the cooperation of the bolt 331 and the nut 332 of the fastener 33, the flanges 12 of the two shells 10 are brought close to each other, and the contact section 311 of the bow member 31 in the extrusion space 121 is pressed against by each flange 12. Under the restriction of the limit block 13, the contact section 311 presses the arc section 312 toward the sealing surface 21 of each sealing layer 20, driving the pushing member 32 to press against the sealing layer 20, so that the sealing layer 20 is fully fitted with the outer wall of the hazardous chemical pipeline 200, thereby effectively reducing the corrosion of the surface of the hazardous chemical pipeline 200 by rust substances through the gap between the sealing surfaces 21 of each sealing layer 20, and achieving corrosion-resistant treatment of the connection of the hazardous chemical pipeline 200.

[0038] The beneficial effects of the corrosion-resistant hazardous chemical pipeline 100 provided in the present application are: the sealing layer 20 is used to protect the connection of the hazardous chemical pipeline 200, the outer shell 10 cooperates with the bow member 31, the push member 32 and the fastener 33 of the extrusion member assembly 30, and the way of extruding the sealing layer 20 and fitting the hazardous chemical pipeline 200 is conducive to driving the outer shells 10 to approach each other by controlling the fastener 33, and applying a force to the bow member 31 in the extrusion space 121 so that the bow member 31 pushes the push member 32 to resist the sealing layer 20, thereby achieving full fit between the connection of the sealing layer 20 and the hazardous chemical pipeline 200. Compared with the method of applying anti-rust oil or paint, it can effectively reduce the time for corrosion-resistant treatment of the connection of the hazardous chemical pipeline 200, thereby reducing the overall laying time of the hazardous chemical pipeline 200 and improving the overall laying efficiency of the hazardous chemical pipeline 200.

[0039] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
