Description

Technical Field

[0001] This utility model relates to the field of pipeline repair, specifically to a steam pipeline repair clamp. Background Technology

[0002] Steam pipelines play a vital role in industrial production, directly impacting energy consumption, environmental protection, and personnel safety. Therefore, the design, installation, maintenance, and management of steam pipeline systems require close attention.

[0003] If a steam pipeline leaks during use, steam operations typically need to be suspended, and the leak point then repaired by welding before steam operations can be restarted. This traditional repair process not only significantly impacts work efficiency due to the suspension of steam operations, but also poses high safety risks due to the use of fire during welding repairs, and results in lengthy repair times and high costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a steam pipe repair clamp, which makes steam pipe repair convenient, eliminates the need for welding, avoids the use of fire, eliminates safety risks, greatly shortens maintenance time and reduces maintenance costs, and does not require interruption of steam operation, thus reducing the impact on work efficiency.

[0005] To solve this technical problem, the present invention adopts the following technical solution:

[0006] A steam pipe repair clamp includes an arc-shaped elastic clamp with the two tail ends of the elastic clamp stacked one on top of the other, wherein the upper stacked part is an outer liner and the lower stacked part is an inner liner.

[0007] The outer end of the outer liner plate is provided with an outer liner plate fastening seat, and the outer side of the inner liner plate is provided with an inner liner plate fastening seat corresponding to the position of the outer liner plate fastening seat. The outer liner plate fastening seat and the inner liner plate fastening seat are fixed by bolts.

[0008] Preferably, the outer liner fastening seat has two through holes for passing bolts in the horizontal direction, and the inner liner fastening seat has two elliptical slots in the horizontal direction corresponding to the through holes. The two bolts are passed through the through holes and slots in sequence, and a nut is set at the outer end of each bolt that extends out of the slot.

[0009] Preferably, the inner side of the outer liner plate is provided with a serrated outer liner plate crimping opening, and the outer side of the inner liner plate is provided with a serrated inner liner plate crimping opening corresponding to the position of the outer liner plate crimping opening, and the outer liner plate crimping opening and the inner liner plate crimping opening are engaged.

[0010] Preferably, the interior of the elastic clip is a cylindrical cavity, and the front and rear edges of the cylindrical cavity are provided with sealing ports.

[0011] More preferably, the inner cavity pressure port includes several annular grooves.

[0012] The positive effects of this utility model are as follows:

[0013] First, this utility model changes the traditional approach to steam pipe repair by replacing the previous welding repair method with a method of pressing and repairing with elastic clips. By using elastic clips, it is easy to quickly fit them onto the outside of the steam pipe and also easy to move the whole steam pipe to the leak point. By setting inner and outer lining plate fastening seats that work together, it is easy to quickly adjust the tightness of the elastic clips when they are fitted onto the outside of the steam pipe.

[0014] Secondly, by setting interlocking outer liner plate pressure ports and inner liner plate pressure ports, this utility model increases the friction between the outer liner plate and the inner liner plate, further enhancing the locking guarantee between the outer liner plate and the inner liner plate, and preventing the inner liner plate from sliding and causing steam leakage when the inner liner plate fastening seat and the outer liner plate fastening seat accidentally loosen.

[0015] Third, by setting an inner cavity pressure port, this utility model achieves tight compression with the positioning hemp fibers on both sides of the steam pipeline leakage point, thereby preventing steam from leaking out from the front and rear sides of the elastic clamp.

[0017] Figure 2 This is a cross-sectional view of the cylindrical inner cavity structure of this utility model. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1As shown, this utility model includes an arc-shaped elastic clip 1 with an axial opening. The elastic clip 1 is made of copper, with a wall thickness of 2mm and a width of 50mm. The two ends of the elastic clip 1 (at the opening) are stacked vertically, with the upper stacked part being the outer liner 6 and the lower stacked part being the inner liner 5. The elastic clip 1, except for the outer liner 6, can form a cylindrical shape (outer diameter 60mm). The interior of the elastic clip 1 is a cylindrical inner cavity 4. The outer side of the outer liner 6 is 34.5mm away from the center of the circumference of the elastic clip 1.

[0020] The outer liner plate 6 has a vertically positioned outer liner plate fastening seat 9 at its outer end. The inner liner plate 5 has a vertically positioned outer liner plate fastening seat 10 corresponding to the outer liner plate fastening seat 9 on its outer side. The outer liner plate fastening seat 9 and the outer liner plate fastening seat 10 are fixed together by bolts 2. The outer liner plate fastening seat 9 has two horizontally oriented through holes for the bolts 2 to pass through. The outer liner plate fastening seat 10 has two horizontally oriented elliptical slots 11 corresponding to the through holes. Two bolts 2 are passed through the through holes and slots 11 sequentially. A nut 3 is placed at the end of each bolt 2 extending out of the slot 11. The bolts 2 are M5 grade, and the shank length of the bolts 2 is 30mm. The nuts 3 are also M5 grade.

[0021] Because the included angle between the outer liner fastener 9 and the outer liner fastener 10 changes dynamically during adjustment, the slot 11 is set to be elliptical to facilitate the angular movement of the bolt 2 within the outer liner fastener 10. By setting the outer liner fastener 10 and the outer liner fastener 9 to cooperate with each other, it is easy to quickly adjust the tightness of the elastic clip 1 when it is fitted onto the outside of the steam pipe.

[0022] The inner side of the outer liner plate 6 is provided with a serrated outer liner plate pressure opening 8, and the outer side of the inner liner plate 5 is provided with a serrated inner liner plate pressure opening 7 corresponding to the position of the outer liner plate pressure opening 8. The outer liner plate pressure opening 8 and the inner liner plate pressure opening 7 are engaged with each other. The outer liner plate pressure opening 8 and the inner liner plate pressure opening 7 are each provided with 10 serrated openings, and the angle of the tip of each serration is 44 degrees.

[0023] By setting the interlocking outer liner plate pressure port 8 and inner liner plate pressure port 7, the friction between the outer liner plate 6 and the inner liner plate 5 is increased, further enhancing the locking guarantee between the outer liner plate 6 and the inner liner plate 5. This prevents the inner liner plate 5 from sliding between the outer liner plate 6 and the outer liner plate 6 when the outer liner plate fastening seat 10 and the outer liner plate fastening seat 9 accidentally loosens, thus preventing steam leakage.

[0024] Figure 1 and Figure 2As shown, the inner edge of the cylindrical cavity 4 is provided with an inner cavity pressure port 12 for sealing at both the front and rear edges. The inner cavity pressure port 12 includes several annular grooves. By setting the inner cavity pressure port 12, it is possible to tightly press it against the positioning hemp fibers on both sides of the steam pipeline leakage point, thereby preventing steam from leaking out from the front and rear sides of the elastic clamp 1.

[0025] The steam pipe repair clamp of this utility model is used as follows:

[0026] Upon discovering a steam pipe leak, there's no need to halt steam operations. Simply wrap hemp fibers around both sides of the leak point for marking and location. Then, manually pry open the outer liner 6 and inner liner 5 of the elastic clip 1, opening it so that the opening is about 20cm from the leak point. Release the clip to return it to its original position, and gently press the outer liner 6 onto the inner liner 5 (leaving a gap between the inner liner 5 and the steam pipe for later movement). Pass the two bolts 2 through the corresponding through holes and slots 11, and screw nuts 3 onto the ends of the bolts 2. Next, use a pry bar, iron pipe, or other tools to move the assembled elastic clip 1 to the leak point in the steam pipe to be repaired, ensuring the inner cavity 4 of the cylinder completely covers the leak point, and the inner cavity openings 12 on both sides of the inner cavity 4 are tightly pressed against the corresponding hemp fibers (the hemp fibers are pressed into the grooves). Gradually tighten the two nuts 3. During the tightening process, the distance between the outer liner fastener 9 and the outer liner fastener 10 continuously decreases, and the outer liner pressure port 8 and the inner liner pressure port 7 continuously press inward, ultimately ensuring that the entire device can completely seal the steam leakage point and prevent steam from overflowing.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
