Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a socket-type pipeline. Background Technology

[0002] Composite spiral wound pipe is a new type of irregularly shaped wall pipe with advantages such as light weight, strong pressure resistance, high joint quality, long service life, corrosion resistance, high ring stiffness, and convenient construction. It is widely used in urban water supply, drainage, long-distance water transmission, and farmland irrigation projects. Composite spiral wound pipe is made by spirally winding strip profiles and interlocking the adjacent sides of each subsequent coil with the previous coil to form a pipe. To increase the strength of the connection, adhesive is usually used at the interlocking points.

[0003] However, during construction, composite spiral wound pipes are installed in sections, and a sealed connection is required between adjacent ends. Existing composite spiral wound pipes have the same diameter at both ends, necessitating the use of additional connectors for mating. This installation method increases the number of connection points, increasing both the workload and the risk of leakage. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a socket-type pipe with reasonable structural design, convenient installation, high strength, which is conducive to reducing construction costs and ensuring construction quality.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A socket-type pipe includes a pipe body, one end of which has a socket formed radially outward, and the outer diameter of the other end of the pipe body matches the inner diameter of the socket, so that adjacent pipe bodies and sockets can be plugged in; the pipe body and socket are integrally spirally wound from a strip profile, and the sides of two adjacent turns of the strip profile are mutually sealed and connected.

[0007] In the above structure, the pipe body and socket are made of integral spiral winding of strip profile, which makes the connection between the two stronger. During construction, adjacent pipe sections can be connected by plugging in the socket, reducing connection points, which helps to reduce construction costs, reduce the risk of leakage, and ensure construction quality.

[0008] Furthermore, the inner side of the tube body and the connector has a strip-shaped liner coated with plastic along the spiral direction, and the edges of two adjacent rings of the strip-shaped liner overlap each other and are integrally glued to form a liner layer; the connection between two adjacent rings of the strip profile is located in the middle of the strip-shaped liner.

[0009] In this way, a strip-shaped inner lining is coated along the spiral direction inside the pipe, and the joint of the strip profile is set in the middle of the strip-shaped inner lining. After the adjacent strip-shaped inner linings form an inner lining layer, the joint of the strip profile will be protected, improving the overall strength and quality of the composite spiral pipe.

[0010] Furthermore, the strip profile is provided with a slot and a protruding strip extending along its length direction, and the cross-sectional shape of the strip matches the cross-sectional shape of the slot; the slot and the strip are respectively located on both sides of the width direction of the strip profile, and two adjacent rings of the strip profile are connected to each other by the slot and the strip.

[0011] In this way, the interlocking between the slots and the strips can increase the connection strength between two adjacent strip profiles and improve the strength of the composite spiral pipe.

[0012] Furthermore, the outer side of the strip profile has protruding ribs that extend along the length of the strip profile.

[0013] In this way, after the strip profile is spirally wound, the outer wall of the composite spiral tube will have spiral ribs, which can increase the strength of the composite spiral tube.

[0014] Furthermore, the outer side of the strip profile has protruding ribs, which are located on one side in the width direction of the strip profile and extend along the length direction of the strip profile; the slot is located on the inner side of the strip profile and is directly opposite to the ribs in the thickness direction of the strip profile; the strip is located on the outer side of the strip profile.

[0015] In this way, the slot and the retaining strip are respectively set on the inner and outer sides of the strip profile. During the spiral winding process, the two interlock radially, giving the formed composite spiral tube a strong axial tensile strength. At the same time, the protruding rib on one side of the strip profile can increase the strength of the slot section, making the interlocking of the slot and the retaining strip more reliable.

[0016] Furthermore, the inner side of the strip profile has a first clearance groove extending along the length direction, and the outer side has a second clearance groove extending along the length direction. The first clearance groove and the second clearance groove are respectively located at the two sides in the width direction of the strip profile, and the sum of their depths is equal to the thickness of the strip profile. The slot is located at the first clearance groove, and the strip is located at the second clearance groove, so that the first clearance groove and the second clearance groove fit together when the slot and the strip are engaged.

[0017] In this way, by setting the first clearance groove and the second clearance groove on the inner and outer sides of the strip profile respectively, and making the sum of their depths equal to the thickness of the strip profile, the inner sides of two adjacent strip profiles are flush when they are in contact with each other, thereby enabling better coating of the strip liner.

[0018] Furthermore, the card strip includes a main card strip with a rectangular cross-section, and the top of the main card strip has a fastening part with a semi-circular cross-section, the width of which is 2-4 mm larger than the width of the main card strip.

[0019] In this way, when the fastener is engaged, the fastening part will push open the slot. Since the cross-sectional shape of the clip and the slot matches, once the fastener is engaged, the outer end of the slot will reset, thus firmly locking the fastening part inside and increasing the strength of the connection.

[0020] Furthermore, the strip profile has two sides extending along the edge in the width direction, and the edge is protruding on the outer side of the strip profile; the edges of two adjacent strip profiles are glued or bonded together.

[0021] Furthermore, the outer side of the strip profile has protruding ribs that extend along the length of the strip profile.

[0022] Furthermore, there is a transition section with a gradually increasing diameter between the tube body and the connector.

[0023] Because of the fixed axial feed speed during the winding process, the strip profiles at the transition section can remain connected to each other by passing through a transition section with a gradually increasing diameter, thus ensuring strength.

[0024] In summary, this utility model has the advantages of reasonable structural design, convenient installation, high strength, and is conducive to reducing construction costs and ensuring construction quality. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the embodiments.

[0030] In practical implementation: such as Figure 1 and Figure 2 As shown, a socket-type pipe includes a pipe body 1, one end of which has a socket 2 formed radially outward, and the outer diameter of the other end of the pipe body 1 matches the inner diameter of the socket 2, allowing adjacent pipe bodies 1 and socket 2 to be inserted and mated. The pipe body 1 and socket 2 are integrally spirally wound from a strip profile 4, and the sides of adjacent turns of the strip profile 4 are mutually sealed and connected. A groove 41 and a protruding retaining strip 42 are provided along the length direction of the strip profile 4, and the cross-sectional shape of the retaining strip 42 matches the cross-sectional shape of the groove 41. The groove 41 and retaining strip 42 are located on both sides of the width direction of the strip profile 4, and adjacent turns of the strip profile 4 are interlocked and connected by the retaining strip 42 and the groove 41.

[0031] The outer side of the strip profile 4 has a protruding rib 44, which is located on one side in the width direction of the strip profile 4 and extends along the length direction of the strip profile 4; the slot 41 is located on the inner side of the strip profile 4 and is directly opposite to the rib 44 in the thickness direction of the strip profile 4; the retaining strip is located on the outer side of the strip profile 4.

[0032] The inner side of the strip profile 4 has a first clearance groove extending along the length direction, and the outer side has a second clearance groove extending along the length direction. The first clearance groove and the second clearance groove are respectively located at the two sides in the width direction of the strip profile 4, and the sum of their depths is equal to the thickness of the strip profile 4. The slot 41 is located at the first clearance groove, and the clip is located at the second clearance groove, so that the first clearance groove and the second clearance groove are mutually fitted when the slot 41 and the clip 42 are engaged.

[0033] To make the connection between the clip and the slot more reliable, the clip 42 includes a main clip with a rectangular cross-section. The top of the main clip has a snap-fit ​​part with a semi-circular cross-section. The width of the snap-fit ​​part is 2-4 mm larger than the width of the main clip. When snapping, the snap-fit ​​part will push open the slot. Since the cross-sectional shapes of the clip and the slot match, once the connection is in place, the outer end of the slot will reset, thus firmly locking the snap-fit ​​part inside and increasing the strength of the connection.

[0034] In this embodiment, the pipe body and socket are made of integral spiral winding of strip profile, which results in a higher connection strength between the two. During construction, adjacent pipe sections can be connected by plugging in the socket, reducing connection points, which helps to reduce construction costs, reduce the risk of leakage, and ensure construction quality.

[0035] Example 2: This example is based on Example 1, such as... Figure 3As shown, the inner sides of the tube body 1 and the connector 2 have strip-shaped inner liners 3 coated with plastic along the spiral direction, and the edges of two adjacent rings of the strip-shaped inner liners 3 overlap each other and are integrally glued to form an inner lining layer; the connection between two adjacent rings of the strip profile 4 is located in the middle of the strip-shaped inner liners 3.

[0036] In this way, a strip-shaped inner lining is coated along the spiral direction inside the pipe, and the joint of the strip profile is set in the middle of the strip-shaped inner lining. After the adjacent strip-shaped inner linings form an inner lining layer, the joint of the strip profile will be protected, improving the overall strength and quality of the composite spiral pipe.

[0037] Example 3: A socket-type pipe, such as Figure 4 As shown, the device includes a tube body 1, one end of which has a radially outwardly expanding socket 2. The outer diameter of the other end of the tube body 1 matches the inner diameter of the socket 2, allowing adjacent tube bodies 1 and socket 2 to be inserted into each other. The tube body 1 and socket 2 are integrally spirally wound from strip profiles 4, and the sides of adjacent turns of the strip profiles 4 are sealed to each other. The inner sides of the tube body 1 and socket 2 have a strip-shaped inner liner 3 coated with plastic along the spiral direction, and the edges of adjacent turns of the strip-shaped inner liner 3 overlap and are integrally glued to form an inner liner layer. The connection between adjacent turns of the strip profiles 4 is located at the middle of the strip-shaped inner liner 3.

[0038] The strip profile 4 has edges 45 extending along its width on both sides, with the edges 45 protruding from the outer side of the strip profile 4; the edges 45 of two adjacent strip profiles 4 are glued or bonded together. The outer side of the strip profile 4 has protruding ribs 43 extending along the length of the strip profile 4. In this embodiment, the external dimensions of the edges of two adjacent strip profiles 4 after being glued or bonded together are consistent with the external dimensions of the ribs 43.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
