Technical Field

[0001] The utility model relates to the technical field of pipe protection, in particular to an anti-corrosion protection sleeve for pipelines. Background Art

[0002] In order to improve the quality of drinking water and prevent some harmful elements to human body from entering the drinking water due to the long-term corrosion of the inner wall of metal pipe fittings by water, metal composite water conveyance pipes have been widely used. The lined stainless steel composite steel pipe or the reinforced stainless steel pipe is a new type of composite steel pipe, and the anti-corrosion and rust-proof treatment inside the pipe has been done very well. However, the port of the composite pipe is easily corroded by the flowing water inside the pipe, which is likely to pollute the water quality and affect the service life of the composite pipe.

[0003] In order to solve the above problems, this case is thus born. Content of the Utility Model

[0008] Preferably, two sealing grooves are arranged on the outer sleeve, and a groove is formed between the two sealing grooves on the outer sleeve.

[0009] Preferably, reinforcing members are arranged at both ends of the outer sleeve.

[0010] Preferably, the protrusions of the sealing grooves on the outer sleeve are flush with the reinforcing members, and the reinforcing members and the protection sleeve are integrally formed.

[0011] (3) Beneficial Effects

[0012] After adopting the above technical solution, compared with the prior art, the utility model has the following advantages: A pipeline anti-corrosion protection sleeve of the utility model is equivalent to fully covering the port of the composite pipe. Sealing grooves are staggered on the inner and outer sleeves. After being pressed with the composite pipe, the sealing effect is better. The groove at the outer sleeve is used for clamp connection. Compared with the groove arranged on the composite pipe body, when clamped, the protection sleeve and the composite pipe are further pressed through the groove, making the two fit better and the sealing effect better. It is difficult for fluid to flow into the space between the protection sleeve and the composite pipe, avoiding corrosion of the composite pipe. Brief Description of the Drawings

[0013] Figure 1 It is a schematic structural diagram of the utility model;

[0014] In the figure: 1 protection sleeve, 11 inner sleeve, 12 outer sleeve, 13 sealing groove, 14 sealing ring, 15 groove, 16 reinforcing member, 2 composite pipe. Detailed Embodiment

[0015] The following further elaborates on the utility model through the drawings and embodiments.

[0016] An embodiment of the utility model provides a pipeline anti-corrosion protection sleeve, as Figure 1 shown, including a protection sleeve 1. The protection sleeve 1 includes an inner sleeve 11 and an outer sleeve 12. The protection sleeve 1 is clamped at the port of the composite pipe 2. The protection sleeve 1 is bent at the port of the composite pipe 2 to form the inner sleeve 11 and the outer sleeve 12. The inner sleeve 11 and the outer sleeve 12 are respectively in close contact with the inner wall and the outer wall of the composite pipe 2. Sealing grooves 13 are opened on both the inner sleeve 11 and the outer sleeve 12. The sealing grooves 13 on the inner sleeve 11 and the outer sleeve 12 are staggered. The staggered arrangement makes the sealing performance stronger. A sealing ring 14 is arranged in the sealing groove 13.

[0017] A pipeline anti-corrosion protection sleeve of the utility model is equivalent to fully covering the port of the composite pipe 2. Sealing grooves 13 are staggered on the inner and outer sleeves. After being pressed with the composite pipe 2, the sealing effect is better. The groove 15 at the outer sleeve 12 is used for clamp connection. Compared with the groove arranged on the composite pipe 2 body, when clamped, the protection sleeve 1 and the composite pipe 2 are further pressed through the groove 15, making the two fit more closely and the sealing effect better. It is difficult for fluid to flow into the space between the protection sleeve 1 and the composite pipe 2, avoiding corrosion of the composite pipe 2.

[0018] There are two sealing grooves 13 on the outer sleeve 12. A groove 15 is formed between the two sealing grooves 13 on the outer sleeve 12. The groove 15 coincides with the groove for clamp connection on the composite pipe 2. Reinforcing members 16 are arranged at both ends of the outer sleeve 12. The protrusions of the sealing grooves 13 on the outer sleeve 12 are flush with the reinforcing members 16. The reinforcing members 16 improve the strength of the protection sleeve 1. The reinforcing members 16 and the protection sleeve 1 are integrally formed. When pressure is applied to the outer sleeve 12 during clamp fixation, the reinforcing members 16 make the protection sleeve not easily deformed.

[0019] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
