Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ductile iron pipes, in particular to a ductile iron pipe with an anti-slip interface. Background Art
[0002] Ductile iron pipes have a low breakage rate, are easy and quick to construct and maintain, have excellent corrosion resistance, and are highly reliable. While conventional ductile iron pipes can adapt to certain foundation deformations, possess a certain degree of seismic resistance, and utilize their deflection angles to achieve long-distance pipeline diversion, they are prone to leaking in areas with complex geological conditions, prone to uneven settlement, or subject to uneven external loads or large load fluctuations. Pipe supports are typically installed at tees, elbows, and reducers to prevent pipeline displacement or joint detachment due to stress. During design and construction, the size of the support supports for large-diameter ductile iron pipes is very large, so addressing the issue of preventing joints from slipping is crucial. Utility Model Content
[0003] The purpose of the present invention is to address the deficiencies of the prior art and provide a ductile iron pipe with an anti-slip interface to solve the problem that the pipeline interface is prone to leakage as mentioned in the above background technology. Usually, piers are required at tees, elbows and reducers to prevent pipeline displacement or interface shedding due to stress. During design and construction, the size of the piers is very large for large-diameter ductile iron pipes, so solving the anti-slip problem of the interface becomes a very important issue.
[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a ductile iron pipe with an anti-slip interface, comprising a first connecting pipe and a second connecting pipe, wherein one end of the first connecting pipe is penetrated and fixed with a through-hole welding ring, the socket welding ring is provided with a limiting groove around it, and one end of the socket welding ring is welded and fixed to one end of the first connecting pipe, one end of the second connecting pipe is welded and fixed to one end of the anti-slip docking device, and the second connecting pipe is docked and fixed to the first connecting pipe via the anti-slip docking device;
[0005] By adopting the above technical solution, a socket welding ring is provided, which not only plays a role in opening a connection, but also plays a role in welding and fixing through one end of the socket welding ring, while playing a role in force penetration through the other end of the socket welding ring. The socket welding ring and the first connecting pipe are welded and fixed in a concentric circle structure in sequence. The concentric circle structure of the two is further improved by welding and fixing the two. The sealing ring and the connectivity after welding are further improved.
[0006] The anti-slip docking device is installed at one end of the second connecting pipe.
[0007] Preferably, the anti-slip docking device includes a socket, a through-hole mounting seat group, a retaining ring group, a threaded hole group, a threaded limiting rod and a sealing ring. The through-hole mounting seat group is welded and fixed to one end of the socket, and the other end of the socket is welded and fixed to one end of the second connecting pipe. The retaining ring group includes an inner retaining ring and an outer retaining ring respectively located on the inner and outer sides of the socket. The outer retaining ring and the through-hole mounting seat group are provided with correspondingly arranged threaded holes and are fixedly connected by nuts. The inner retaining ring group is welded and fixed to the inner ring of the socket. The inner retaining ring is provided with a threaded hole group. The inner retaining ring is threadedly connected to the threaded limiting rod through the threaded hole group, and the sealing ring is matched with the inner ring of the socket.
[0008] By adopting the above technical solution, a sealing ring is provided, which not only plays a through-matching connection effect with the socket, but also plays a force-driven and force-relative penetrating movement effect. At the same time, the sealing ring sequentially improves the through-sealing connection effect between the socket and the socket welding ring and the first connecting pipe.
[0009] Preferably, there are four limiting grooves, and the limiting grooves are opened in a circular array manner about the socket welding ring.
[0010] By adopting the above technical solution, a limit groove is provided, which has a through-connection effect on the threaded limit rod, and has a motion limiting effect on the threaded limit rod. At the same time, the depth distance interval of the limit groove is 5 cm, which avoids the situation where the depth of the limit groove is too shallow, resulting in the threaded limit rod being easily separated from the limit groove during the force process.
[0011] Preferably, the connection shape of the socket and the through-hole mounting seat group is in the shape of a ceiling fan base.
[0012] By adopting the above technical solution, a through-hole mounting seat group is provided, which also has the effect of welding and fixing, and also has the effect of penetrating and matching fixed connection. At the same time, the through-hole mounting seat group can successively achieve the effects of force movement and force relative movement.
[0013] Preferably, the distance between the inner side transverse diameters of the through-hole mounting seat group and the bottom transverse diameter of the retaining ring group is less than 0.2-0.35 cm.
[0014] By adopting the above technical solution, a retaining ring group is provided, which also plays the role of penetrating and opening the connection, and also plays the role of force fixing and force penetrating connection. At the same time, the retaining ring group adopts retaining ring groups of different sizes to set up the connection, so as to avoid the situation where the retaining ring groups all adopt the same retaining ring group to be fixedly connected with the socket, resulting in force limiting the socket welding ring.
[0015] Preferably, the inner retaining ring, the threaded hole group and the threaded limiting rod constitute a rotation adjustment mechanism, and the rotation adjustment distance range of the rotation adjustment mechanism is 0-5 cm.
[0016] By adopting the above technical solution, a threaded limit rod is provided, and a threaded connection effect is achieved through one end of the threaded limit rod and the threaded hole group, and a relative sliding movement effect is achieved through the other end of the threaded limit rod and the limit groove. At the same time, the threaded limit rod plays a role in adjusting the force length in turn.
[0017] The beneficial effects of the utility model are:
[0018] 1. A socket welding ring and a limit groove are provided. During the force application process of the second connecting pipe, the retaining ring group drives the threaded limit rod and the limit groove to slide relative to each other. When the threaded limit rod and the limit groove are in sliding limit contact, the first connecting pipe and the second connecting pipe are prevented from slipping and detaching, thereby avoiding leakage of the pipeline interface. Usually, piers are required at tees, elbows and reducers to prevent pipeline displacement or interface detachment due to stress. In design and construction, the size of the piers is very large for large-diameter ductile iron pipes, so it is very important to solve the problem of anti-slipping of the interface.
[0019] 2. An anti-slip docking device is provided. When the first connecting tube and the second connecting tube are docked and fixed, the socket welding ring is driven to penetrate the socket during the force process of the first connecting tube so that the through-hole welding ring and the retaining ring group are in limited contact. After the first connecting tube and the second connecting tube are relatively connected, the threaded limiting rod is manually rotated to extend into the limiting groove to prevent the first connecting tube and the second connecting tube from being easily separated after being subjected to force. When the retaining ring group and the through-hole welding ring are fixedly connected, the stability of the first connecting tube and the second connecting tube after connection is improved. At the same time, the sealing effect of the connection between the first connecting tube and the second connecting tube is improved in turn through the sealing ring, thereby avoiding the above situation again.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] See also Figure 1-3 The utility model provides a technical solution: a ductile iron pipe with an anti-slip interface, such as Figure 1 As shown, a through-hole welding ring 2 is welded and fixed on one end of the first connecting tube 1, and a limiting groove 4 is provided around the socket welding ring 3. There are 4 limiting grooves 4, and the limiting grooves 4 are provided in a circular array manner about the socket welding ring 3. There are 4 limiting grooves provided through the above structure, which not only reflects the practicality of the above structure, but also reflects the symmetry of the above structure, and again reflects the connectivity and penetration limiting effect of the above structure. At the same time, the above structure and the socket welding ring 3 are provided in a circular array manner, which in turn avoids the situation where the above structure and the threaded limiting rod 505 are connected in a single group manner, thereby reducing the force connectivity. One end of the socket welding ring 3 is welded and fixed to one end of the first connecting tube 1, and one end of the second connecting tube 6 is welded and fixed to one end of the anti-slip docking device 5, and the second connecting tube 6 is docked and fixed to the first connecting tube 1 through the anti-slip docking device 5.
[0027] like Figure 2As shown, the anti-slip docking device 5 is installed at one end of the second connecting pipe 6, and the anti-slip docking device 5 includes a socket 501, a through-hole mounting seat group 502, a retaining ring group 503, a threaded hole group 504, a threaded limiting rod 505 and a sealing ring 506. The through-hole mounting seat group 502 is welded and fixed to the outer ring of one end of the socket 501. The connection shape of the socket 501 and the through-hole mounting seat group 502 is in the shape of a ceiling fan base. The connection shape of the above two is in the shape of a ceiling fan base, which not only reflects the symmetrical dispersion of the connection between the above two, but also reflects the four-way fixed connection effect of the connection between the above two, and again reflects the connection between the above two. The limiting docking and rotation docking effects, at the same time, the connection shape of the above two is in the shape of a ceiling fan base, which reflects the axial symmetry effect of the connection between the above two in turn. The retaining ring group 503 includes an inner retaining ring and an outer retaining ring respectively located on the inner and outer sides of the socket 501, and the outer retaining ring and the through-hole mounting seat group 502 are provided with correspondingly arranged threaded holes and are fixedly connected by nuts. The inner retaining ring group is welded and fixed to the inner ring of the socket 501, and the inner retaining ring is provided with a threaded hole group 504. The inner retaining ring is threadedly connected to the threaded limiting rod 505 through the threaded hole group 504, and the sealing ring 506 is matched with the inner ring of the socket 501.
[0028] like Figure 3As shown, the inner retaining ring is threadedly connected to the threaded limiting rod 505 through the threaded hole group 504. The inner retaining ring, the threaded hole group 504 and the threaded limiting rod 505 constitute a rotation adjustment mechanism, and the rotation adjustment distance range of the rotation adjustment mechanism is 0-5cm. When the second connecting tube 6 is connected with the first connecting tube 1, the threaded limiting rod 505 is manually rotated to move. During the force movement of the threaded limiting rod 505, it rotates relative to the inner retaining ring through the threaded hole group 504. When the threaded limiting rod 505 extends inside the limiting groove 4, the rotation of the threaded limiting rod 505 stops, and the rotation adjustment distance range of the overall rotation adjustment mechanism is 0-5cm. The distance between the two ends of the retaining ring 503 and the inner side of the through-hole mounting seat group 502 is less than 0.2-0.35cm. If the distance between the inner side of the through-hole mounting seat group 502 and the inner side of the retaining ring group 503 is too shorter than the distance between the inner side of the through-hole mounting seat group 502 and the inner side of the retaining ring group 503, the retaining ring group 503 will not be able to be connected with the inner side of the through-hole mounting seat group 502 during the force application. When the above two cannot be connected through and matched, it is necessary to grind one of the two components. However, grinding not only increases the construction time, but also increases the grinding process and labor costs. Therefore, in order to avoid the above situation, the inner side lateral diameter distance of the through hole mounting seat group 502 is set to be less than 0.35 cm than the bottom lateral diameter distance of the retaining ring group 503. The sealing ring 506 is matched with the inner ring of the socket 501, and the other end of the socket 501 is welded and fixed to one end of the second connecting pipe 6.
[0029] Working principle: When using the anti-slip interface ductile iron pipe, first manually apply thrust to the first connecting pipe 1 and the second connecting pipe 6 relative to each other. At this time, the above two respectively drive the through-hole weld ring 2, the socket weld ring 3 and the socket 501 to move relative to each other. When the socket weld ring 3 is subjected to force to penetrate the socket 501, the socket weld ring 3 penetrates the inner retaining ring and extends into the second connecting pipe 6. When the second connecting pipe 6 and the first connecting pipe 1 are in a through-connected state, the threaded limit rod 505 is manually rotated to extend into the limit groove 4, thereby limiting the movement. Then, the fixing nut is passed through the through-hole weld ring 2 and the retaining ring group 503 through the sealing ring 506 to seal and fix the first connecting pipe 1 and the second connecting pipe 6. This completes the entire operation, and the content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
