[0002] As a composite pipe with excellent performance, continuously wound FRP pipe has advantages that cannot be replaced by other pipes, such as light weight, high strength, corrosion resistance, excellent hydraulic performance, strong designability, stable quality, etc. Its comprehensive economic and social benefits are also very significant. It has been widely used in many fields and industries such as municipal construction, petrochemical industry, water conservancy and irrigation, fire safety, submarine drainage, pressure water supply, aquaculture, sewage treatment, etc. in my country.

[0003] The joints of continuously wound FRP pipes are conventionally connected by flexible connections, that is, they are connected using integral rubber sealing ring sleeve joints. This connection method can be moved in the axial direction of the pipeline. When the temperature changes, the length of the pipeline has a certain amount of expansion and contraction; or when the pipeline is subjected to axial force at the location of the pipeline fittings; or in special circumstances, such as the seabed and complex locations, this sleeve joint is prone to falling off. At present, continuously wound FRP pipes are generally outsourced at this location, with external clamps or holes drilled on the pipe to fix the lock on the pipe. However, this method is time-consuming and labor-intensive, and the operation is troublesome, or there are hidden dangers in the pipeline, which needs to be further optimized.

[0004] Therefore, a limiter device for a glass fiber reinforced plastic sleeve joint is proposed to further improve it. Utility Model Content

[0017] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0018] See also Figure 1-2The utility model provides a limiter device of a glass fiber reinforced plastic sleeve joint, comprising a first pipe 1, a second pipe 2, a glass fiber reinforced plastic sleeve joint 3, a limiter 4, a bolt rod 5 and a nut 6. The second pipe 2 is relatively arranged on the right side of the first pipe 1, and the glass fiber reinforced plastic sleeve joint 3 is butted on the left side of the second pipe 2. The combined connection activity of the first pipe 1 and the second pipe 2 can be efficiently and accurately realized through the glass fiber reinforced plastic sleeve joint 3. The first pipe 1 and the second pipe 2 are both externally provided with a limiter 4 for convenient pipe butt connection, avoiding the problems of outsourcing the glass fiber reinforced plastic sleeve joint 3 and time-consuming and labor-intensive external installation of a clamping ring, and the like. A bolt rod 5 is penetrated inside the limiter 4, and a nut 6 is threadedly butted on the outer side of the bolt rod 5. Thus, through the arrangement of the bolt rod 5 and the nut 6, the connection combination of the limiter 4 arranged on the outer side of the first pipe 1 and the second pipe 2 can be realized to ensure the convenience and efficiency of the overall butt connection of the first pipe 1 and the second pipe 2.

[0019] Among them, the inner diameter of the FRP sleeve joint 3 is consistent with the diameter of the first pipe 1 and the second pipe 2, and the FRP sleeve joint 3 connects the first pipe 1 and the second pipe 2, so that the docking and combination activities of the first pipe 1 and the second pipe 2 can be efficiently realized; the number of bolt rods 5 and nuts 6 is not less than four groups, and the bolt rods 5 and nuts 6 on each side are respectively connected to the limiters 4 provided on the outside of the first pipe 1 and the second pipe 2, so that the first pipe 1 and the second pipe 2 can be efficiently docked and locked when the bolt rods 5, nuts 6 and the limiters 4 are docked.

[0020] See also Figure 3 The limiter 4 in this embodiment includes a retaining ring 41 respectively arranged on the outside of the first pipe 1 and the second pipe 2 to achieve docking and limiting cooperation, a locking ear 42 equidistantly fastened to the inside of the retaining ring 41, and the inside of the locking ear 42 is connected to the bolt rod 5, a glass fiber winding groove 43 is opened in the retaining ring 41, and a glass fiber main body 44 is wound in the glass fiber winding groove 43. When the glass fiber main body 44 is wound in the glass fiber winding groove 43, the first pipe 1 or the second pipe 2 with the limiter 4 needs to be installed on the external rotary mechanism, and then the glass fiber main body 44 impregnated with resin is wound on the glass fiber winding groove 43 in the retaining ring 41, and after curing and molding, two pipe sockets with the limiter 4 device are formed. In this way, the first pipe 1 and the second pipe 2 can be docked more conveniently and quickly through the winding and curing of the glass fiber main body 44, and at the same time, the docking position is made corrosion-resistant and vibration-resistant.

[0021] Among them, the limiter 4 is installed along the outer side of the first pipe 1 or the second pipe 2, and the locking ears 42 arranged inside the limiter 4 are equidistantly arranged along the circular track, ensuring that the limiter 4 can be flexibly installed according to the first pipe 1 or the second pipe 2 of different sizes to meet the convenient docking requirements of different first pipes 1 or second pipes 2; the locking ears 42 are installed at the middle end of the inner part of the retaining ring 41, and the glass fiber winding grooves 43 are formed between the locking ears 42 and the left and right sides of the retaining ring 41, ensuring that the glass fiber winding grooves 43 formed on both sides of the locking ears 42 and the retaining ring 41 can be used for winding and curing the glass fiber body 44, so as to make the pipe docking fast and convenient and the docking position stable, corrosion-resistant and vibration-resistant. In addition, the pipe stiffness at the pipe socket can be increased, and the external load resistance capacity at the socket is improved.

[0022] Here’s how it works:

[0023] When the limiter device of the FRP sleeve joint is to be used, Figure 1 As shown in the figure, retaining rings 41 are installed on the outside of the first pipe 1 and the second pipe 2, respectively, and the size of the retaining ring 41 needs to be selected according to the glass fiber reinforced plastic sleeve joint 3 provided on the left side of the second pipe 2;

[0024] After the retaining ring 41 is connected to the outside of the first pipe 1 or the second pipe 2, the first pipe 1 or the second pipe 2 with the stopper 4 is connected to the external rotary mechanism, and then the glass fiber body 44 impregnated with resin is wound on the glass fiber winding groove 43 provided inside the retaining ring 41, so that after curing and molding, two pipe sockets with the stopper 4 are formed;

[0025] Subsequently, the FRP sleeve joint 3 is installed at the socket of the first pipe 1 and the second pipe 2 with the limiter 4. During installation, the limiters 4 on both sides need to be aligned to ensure the left-right symmetry of the locking ears 42 on both sides. In this way, the bolt rod 5 can be inserted into the locking ears 42 on both sides in sequence, and the nuts 6 are used to achieve the threaded locking of the left and right locking ears 42 and the bolt rod 5. When the locking ears 42 at other positions are threadedly connected with the bolt rod 5 and the nuts 6, the first pipe 1 and the second pipe 2 can be quickly and conveniently connected. This docking installation method is easy to implement during the manufacturing process, avoiding the time-consuming and labor-intensive problems of outsourcing and externally installing the clamping ring at the FRP sleeve joint 3, and also avoiding the late hidden dangers of opening holes on the pipe. At the same time, the setting of the limiter 4 can also effectively adjust the deflection angle of the pipe installation, which is of great benefit to the pipe installation.

[0026] Furthermore, by winding the glass fiber main body 44 into the glass fiber winding groove 43 opened inside the retaining ring 41 to perform curing and molding activities, the first pipe 1 can be connected with the second pipe 2 and the fiberglass sleeve joint 3 to achieve high-efficiency corrosion resistance and vibration resistance, thereby avoiding corrosion leakage or vibration leakage problems when the first pipe 1 and the second pipe 2 are connected.

Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
