Description

Technical Field

[0001] This utility model relates to the field of flange protection technology, specifically to a leak-proof flange protective sleeve. Background Technology

[0002] A flange sleeve is a protective device used at the flange connection of a pipeline. It is usually made of plastic or composite materials. Its main function is to wrap the flange face and bolts to prevent dust, moisture, corrosive media and other substances in the external environment from corroding the flange connection.

[0003] Traditional flange sleeves consist of two semi-circular sleeves connected together, with a through hole in the center for pipes to pass through. However, the diameter of the central through hole cannot be changed, which prevents it from completely fitting the pipe wall with a smaller diameter. This allows rainwater or impurities to easily enter the interior through the gap between the central through hole and the pipe wall, reducing the protective effect. Therefore, there is an urgent need for a leak-proof flange sleeve to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a leak-proof flange protection sleeve to solve the problem mentioned in the background art that the traditional flange sleeve consists of two semi-circular sleeves connected together, with a through hole in the center for the pipe to pass through. However, the diameter of the central through hole cannot be changed, which makes it impossible for it to fit completely with the pipe wall of a smaller diameter pipe. As a result, rainwater or impurities can easily enter the interior from the gap between the central through hole and the pipe wall, reducing the protective effect.

[0005] This utility model provides the following technical solution: a leak-proof flange protective sleeve, including a protective mechanism, wherein the protective mechanism includes two symmetrical C-shaped sleeves, one end of which is connected and the other end is locked in place;

[0006] It also includes an adapter mechanism, which includes rubber rings distributed at the central opening of the C-shaped sleeve, and is shaped like a frustum with a cone head away from the flange;

[0007] The area of ​​the rubber ring that is not connected to the C-shaped sleeve has a strip-shaped notch, and the outer diameter of the rubber ring on one C-shaped sleeve is equal to the inner diameter of the rubber ring on the other C-shaped sleeve, so that the two rubber rings are successively fitted onto the outside of the pipe wall.

[0008] To achieve the above technical solution, a rubber ring is adhered to the central opening of the C-shaped sleeve. With two rubber rings, it can be successively fitted onto the outside of the pipe, thereby shielding and protecting the gap between the central opening of the C-shaped sleeve and the pipe wall. Compared with the existing technology, this device has a better anti-leakage effect, and rainwater and impurities are less likely to enter the C-shaped sleeve chamber, thus improving the protection effect on the flange.

[0009] As a further improvement to this utility model, the central opening of the C-shaped sleeve is thickened in an annular shape.

[0010] The above technical solution improves the strength of the C-shaped annular opening.

[0011] As a further improvement to this utility model, a counterweight is connected to each of the C-shaped sleeves, so that the openings of the two C-shaped sleeves after splicing are naturally horizontal.

[0012] The above technical solution makes it less likely for the C-shaped sleeve to rotate along the flange after it is fixed.

[0013] As a further improvement to this utility model, the C-shaped sleeve around the counterweight is provided with ventilation holes for moisture to escape from the C-shaped sleeve cavity.

[0014] The above technical solution facilitates the discharge of moisture from the C-shaped cavity.

[0015] As a further improvement to this utility model, the rubber ring strip notches on the two C-shaped sleeves are flipped and aligned.

[0016] The above technical solution improves the shielding effect of the rubber ring on the strip-shaped notch of the other rubber ring.

[0017] As a further improvement to this utility model, the rubber ring is thicker closer to the flange.

[0018] The above technical solution improves the strength of the rubber ring itself.

[0019] As a further improvement to this utility model, the inner wall and surface of the rubber ring are uniformly provided with deformation grooves in a ring shape.

[0020] The above technical solution makes the deformation groove easier to deform.

[0021] The technical effects and advantages of this utility model are as follows:

[0022] 1. This utility model uses a C-shaped sleeve with an adhesive ring attached to the central opening. With the addition of two adhesive rings, it can be successively fitted onto the outside of the pipe, thereby shielding and protecting the gap between the central opening of the C-shaped sleeve and the pipe wall.

[0023] 2. Compared with the prior art, this device has a better anti-leakage effect, and rainwater and impurities are less likely to enter the C-shaped sleeve cavity, thus improving the protection effect on the flange. Attached Figure Description

[0031] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1:

[0033] Refer to the attached diagram in the instruction manual. Figure 1-4 This utility model provides a leak-proof flange protection sleeve, including a protection mechanism 100 and an adapter mechanism 200;

[0034] The two C-shaped sleeves 110 in the protective mechanism 100 are made of plastic (5mm thick). They are symmetrical semi-circular structures (150-200mm in diameter), connected at one end (rotation angle 0-180°), and the other end is equipped with a snap-on locking structure. The whole is injection molded as one piece.

[0035] The rubber ring 210 in the adapter mechanism 200 is made of butyl rubber (temperature resistance range -40℃~120℃), and has a frustum-shaped structure (the diameter of the large end is 10~15mm larger than that of the small end, and the height is 30mm). The cone head is away from the flange direction, and a strip-shaped notch (width 8mm) is opened in the non-connection area. The rubber rings 210 on the two C-shaped sleeves 110 form a nested structure (the outer diameter of one is equal to the inner diameter of the other, and the gap is ≤2mm). The strip-shaped notch is distributed in a flipped alignment.

[0036] The thickness of the rubber ring 210 gradually increases near the flange end (from 5mm to 10mm), and annular deformation grooves 211 (semi-circular cross-section, 3mm diameter, 5mm spacing) are opened on the inner wall and surface to improve the radial deformation capacity (maximum deformation is increased).

[0037] Installation process:

[0038] Flip open the two C-shaped sleeves 110 and cover the pipe flange connection;

[0039] When fixing the small outer diameter rubber ring 210, manually open the rubber ring along the strip-shaped notch, and let it be externally supported and covered by the elastic deformation of the deformation groove 211 to cover the outer wall of the pipe (covering pressure 0.3-0.5MPa);

[0040] When nesting the large outer diameter rubber ring 210, the same operation is performed to cover the outside of the previous rubber ring 210, and the inner layer notch is completely covered by the notch flipping and alignment design.

[0041] Snap the C-shaped sleeve 110 to complete the overall fixation (the rubber ring 210 achieves double sealing through interference fit).

[0042] Example 2:

[0043] Refer to the attached diagram in the instruction manual. Figure 3 The difference between this embodiment and the above embodiment is that the C-shaped sleeve 110 has a reinforced structure and a moisture-proof design;

[0044] Structural optimization: The center opening of the C-shaped sleeve 110 is thickened in an annular shape (thickness increased to 8mm to enhance the connection strength with the rubber ring 210). A counterweight 111 (cast iron material, weight 500-800g) is attached to the inside or outer wall of a single C-shaped sleeve 110. The counterweight 111 keeps the openings of the two C-shaped sleeves 110 naturally horizontal after splicing.

[0045] Moisture-proof system: Six ventilation holes 112 (5mm in diameter, 30mm between holes) are evenly opened on the C-shaped sleeve 110 around the counterweight 111. The ventilation holes 112 are connected to the inner cavity of the C-shaped sleeve 110. The ventilation holes 112 form a natural convection channel to discharge the condensed moisture in the cavity of the C-shaped sleeve 110 and reduce the risk of condensation on the inner wall.
