Description

Technical Field

[0001] This utility model relates to fiberglass pressure pipe joints, specifically an integrated fiberglass pressure pipe joint structure. Background Technology

[0002] In recent years, the demand for long-distance water pipelines has been increasing both domestically and internationally, leading to a significant increase in the requirements for pipeline pressure resistance. Simultaneously, the requirements for pipeline connection devices are also becoming more stringent. Currently, pressure pipeline joints on the market are mainly full-width sleeves, but these are costly and inconvenient to install on construction sites. Furthermore, existing joint technologies often experience problems during construction, such as misalignment or folding of the rubber ring, resulting in water leakage, or even the rubber ring detaching from the joint. Therefore, this paper proposes an integrated fiberglass pressure pipe joint structure. Utility Model Content

[0003] The purpose of this invention is to provide an integrated fiberglass pressure pipe connector structure to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a connector structure for an integrated fiberglass pressure pipe, characterized by including an inner rubber sealing layer, a fiberglass layer disposed on the outer side of the rubber sealing layer through a one-time composite molding process, and a reinforcing structure disposed on the outer wall of the rubber sealing layer to enhance the connection between the rubber sealing layer and the fiberglass layer and prevent the rubber sealing layer from falling off the fiberglass layer. The reinforcing structure includes a plurality of anti-detachment grooves and anti-detachment blocks disposed on the outer side of the rubber sealing layer in an alternating manner. When the fiberglass layer is disposed on the rubber sealing layer through a one-time composite molding process, a limiting block adapted to the anti-detachment groove and a limiting groove adapted to the anti-detachment block are formed in the anti-detachment groove.

[0005] More preferably, the anti-detachment groove and the anti-detachment block are inclined, and the inclination directions of the anti-detachment groove and the anti-detachment block are opposite.

[0006] A further preferred embodiment includes a partition disposed inside the rubber sealing layer to limit and prevent impact on the inner tube of the insertion joint, and several sealing lips disposed inside the rubber sealing layer and on both sides of the partition.

[0007] The beneficial effects of this utility model are: the fiberglass layer is set on the rubber sealing layer through one-time composite molding, so that the rubber sealing layer and the fiberglass layer are set as one piece, which improves the overall pressure resistance of the joint and the anti-detachment between the rubber sealing layer and the fiberglass layer.

[0008] By enhancing the structure and setting several anti-detachment grooves and blocks in an alternating pattern on the outside of the rubber sealing layer, when the fiberglass layer is formed in a one-time composite molding process on the outside of the rubber sealing layer, a limiting block adapted to the anti-detachment groove and a limiting groove adapted to the anti-detachment block are formed on the inside of the fiberglass layer. The cooperation between the anti-detachment groove and the limiting block, as well as the cooperation between the anti-detachment block and the limiting groove, effectively enhances the firmness of the bond between the rubber sealing layer and the fiberglass layer, and effectively limits the axial position between the rubber sealing layer and the fiberglass layer. This prevents the rubber sealing layer from being misaligned, flipped, or separated from the fiberglass layer when the pipe is pushed into the rubber sealing layer during construction.

[0014] The following description, in conjunction with the accompanying drawings, further illustrates the joint structure of an integrated fiberglass pressure pipe according to this utility model.

[0015] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] See Figures 1-4As shown, a joint structure for an integrated fiberglass pressure pipe is characterized by including an inner rubber sealing layer 1, a fiberglass layer 2 formed by a one-time composite molding on the outer side of the rubber sealing layer 1, and a reinforcing structure on the outer wall of the rubber sealing layer 1 to enhance the connection between the rubber sealing layer 1 and the fiberglass layer 2 and prevent the rubber sealing layer 1 from falling off the fiberglass layer 2. The reinforcing structure includes a plurality of anti-detachment grooves 3 and anti-detachment blocks 4 arranged in an alternating manner on the outer side of the rubber sealing layer 1. When the fiberglass layer 2 is formed on the rubber sealing layer 1 by a one-time composite molding, a limiting block 5 adapted to the anti-detachment groove 3 and a limiting groove 6 adapted to the anti-detachment block 4 are formed in the anti-detachment groove 3.

[0018] The fiberglass layer 2 is integrally formed on the rubber sealing layer 1 through a one-time composite molding process, making the rubber sealing layer 1 and the fiberglass layer 2 an integrated unit. This improves the overall pressure resistance of the joint and the anti-detachment properties between the rubber sealing layer 1 and the fiberglass layer 2. The fiberglass layer 2 on the outer surface of the rubber sealing layer 1 is made of continuous glass fiber, unidirectional glass fiber cloth, and thermosetting resin through a one-time composite molding process. The rubber sealing ring and the fiberglass layer 2 will never fall off, and the sleeve and pipe are easy and quick to install, avoiding water leakage caused by the rubber ring being misaligned or flipped during construction.

[0019] By enhancing the structure, and by setting several anti-detachment grooves 3 and anti-detachment blocks 4 in an alternating manner on the outside of the rubber sealing layer 1, when the fiberglass layer 2 is formed in a one-time composite molding process on the outside of the rubber sealing layer 1, a limiting block 5 that matches the anti-detachment groove 3 and a limiting groove 6 that matches the anti-detachment block 4 are formed on the inside of the fiberglass layer 2. The cooperation between the anti-detachment groove 3 and the limiting block 5, as well as the cooperation between the anti-detachment block 4 and the limiting groove 6, effectively enhances the firmness of the bond between the rubber sealing layer 1 and the fiberglass layer 2, and effectively limits the axial position between the rubber sealing layer 1 and the fiberglass layer 2. This prevents the rubber sealing layer 1 from being misaligned, flipped, or separated from the fiberglass layer 2 when the pipe is pushed into the rubber sealing layer 1 during construction.

[0020] In one embodiment, the anti-detachment groove 3 and the anti-detachment block 4 are inclined, and the inclination directions of the anti-detachment groove 3 and the anti-detachment block 4 are opposite.

[0021] By setting the anti-detachment groove 3 and the anti-detachment block 4 at an angle, and setting the angles of the anti-detachment groove 3 and the anti-detachment block 4 in opposite directions, the axial position between the rubber sealing layer 1 and the fiberglass layer 2 is limited, thus preventing misalignment or even separation between the rubber sealing layer 1 and the fiberglass layer 2 due to the squeezing force during the insertion of the tube into the rubber sealing layer 1.

[0022] In one embodiment, it further includes a partition 7 disposed inside the rubber sealing layer 1 to limit and prevent collision of the inner tube of the insertion connector, and a plurality of sealing lips 8 disposed inside the rubber sealing layer 1 and on both sides of the partition 7.

[0023] By setting the partition 7, the insertion distance of the pipe body is limited when the pipe body is inserted into the joint, so as to avoid the inconsistent insertion distance of the two pipe bodies into the joint and thus affect the firmness of the connection. At the same time, it also acts as a buffer between the ends of the two pipe bodies when the pipe body is inserted, so as to avoid collision with the end of the other pipe body and cause damage.

[0024] By providing several sealing lips 8 on the inner side of the rubber sealing layer 1 and on both sides of the partition 7, and by providing compression grooves 9 on the several sealing lips 8 on both sides of the partition 7, the compression grooves 9 on the several sealing lips 8 gradually increase from the outside to the inside. Through the gradually increasing compression grooves 9, the compression ratio of the several sealing lips 8 is different. Multiple seals are formed by multiple sealing lips 8. After being compressed, the sealing lips 8 fit tightly with the pipe body to prevent leakage. At the same time, it can also prevent groundwater from entering the pipe body and causing pollution.

[0025] During pipe installation, simply insert one end of the pipe into the connector until the end of the pipe touches one side of the partition 7 inside the rubber sealing layer 1, and then insert one end of the other pipe into the other end of the connector until the other end of the other pipe touches the other end of the partition 7 to complete the connection between the pipe and the connector.

[0026] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
