Description

Technical Field

[0001] This utility model relates to the field of fiberglass pipe technology, specifically to a fiberglass sleeve connection device. Background Technology

[0002] Fiberglass, also known as glass fiber reinforced plastic, includes fiberglass pressure pipes (process pipes), which are a new type of composite pipe composed of glass fiber and unsaturated polyester resin.

[0003] Chinese utility model patent CN219076578U discloses a fiberglass pipe positioning and docking device, including a sleeve component and rubber rings evenly arranged on the inner wall of the sleeve component. The sleeve component is a circular tube structure with open ends, and the inner diameter of the sleeve component is larger than the inner diameter of the fiberglass pipe. Four grooves are evenly arranged on the inner wall of each end of the sleeve component, and a rubber ring is fixed in each groove. The fiberglass pipe is directly inserted into the docking device, and the surface of the rubber ring is tightly connected and fits the outer wall of the fiberglass pipe, effectively ensuring the reliability of the connection between the pipe socket and spigot. A reverse clamp is provided to effectively provide connection stability and prevent the fiberglass pipe from being pulled out of the docking device. A stop is provided to effectively ensure the symmetry of the connection between the fiberglass pipes on both sides of the docking device and avoid the problem of over-insertion of the fiberglass pipe on one side, resulting in good connection reliability.

[0004] The fiberglass pipe connection device in the above scheme directly inserts the fiberglass pipe into the connection device, so that the surface of the rubber ring is tightly connected and fits the outer wall of the fiberglass pipe, thereby connecting the two glass sleeves. In actual use, if the medium flowing in the pipe is liquid or gas, due to the presence of pressure, the medium will flow out from the gap between the rubber ring and the groove, causing leakage at the connection and affecting the normal operation of the pipeline system.

[0015] 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.

[0016] like Figures 1-2As shown, this utility model provides a technical solution: a fiberglass sleeve connection device, including a connecting sleeve 3, the inner wall of which is integrally formed with a first extension plate 301, a first fiberglass pipe 1 and a second fiberglass pipe 2 are inserted into the connecting sleeve 3 and located on both sides of the first extension plate 301. To improve the sealing performance, annular rubber gaskets 4 are fixed on both sides of the first extension plate 301. After installation, the ends of the first fiberglass pipe 1 and the second fiberglass pipe 2 are respectively squeezed against the two annular rubber gaskets 4. Through the elastic deformation of the annular rubber gaskets 4, the sealing performance at the connection between the connecting sleeve 3 and the annular rubber gaskets 4 is enhanced, and the first layer of sealing between the connecting sleeve 3 and the first fiberglass pipe 1 and the second fiberglass pipe 2 is achieved.

[0017] A second extension plate 302 is formed on the inner wall of both sides of the connecting sleeve 3. It is known that the second extension plate 302 is clearance-fitted with the fiberglass pipe. A rubber ring 5 is provided on the outer side of the second extension plate 302. In addition, a pressing component is provided on the outer side of the rubber ring 5. The pressing component squeezes the outer side of the rubber ring 5, causing the rubber ring 5 to deform. In this solution, in order to further improve the adaptability and sealing effect of the rubber ring 5, a cavity is specially opened inside the rubber ring 5. This design allows the rubber ring 5 to deform better when squeezed by the pressing component, thereby filling the tiny gap between the connecting sleeve 3 and the fiberglass pipe, effectively preventing media leakage, and realizing the second layer of sealing between the connecting sleeve 3 and the first fiberglass pipe 1 and the second fiberglass pipe 2.

[0018] like Figure 2 As shown, the pressure-blocking assembly includes a baffle 6 fixed to the bodies of the first fiberglass pipe 1 and the second fiberglass pipe 2. A pressure-blocking part is provided on the top of the baffle 6. The pressure-blocking part includes a threaded tube 701 that is movably screwed to the body of the connecting sleeve 3. A side plate 704 and a support plate 702 are formed on the inner side of the threaded tube 701. The side plate 704 is located at the end face of the threaded tube 701. The cross-section of the side plate 704 is L-shaped. It is inserted into the gap formed between the connecting sleeve 3 and the fiberglass pipe, and its end is located on one side of the rubber ring 5. In addition, a pressure plate 703 is fixed at the end of the support plate 702. After the connection device is installed, the side plate 704 and the baffle 6 are pressed together to achieve a third layer of sealing between the connecting sleeve 3 and the first fiberglass pipe 1 and the second fiberglass pipe 2.

[0019] Specifically, during installation, the pressure-retaining part is inserted into the body of the fiberglass pipe. Then, the first fiberglass pipe 1 and the second fiberglass pipe 2 are moved towards each other until the end faces of the first fiberglass pipe 1 and the second fiberglass pipe 2 respectively contact the side of their corresponding annular rubber pads 4. Then, the connecting sleeve 3 is fixed in place by a tool. The screw tube 701 is rotated. As the screw tube 701 rotates, it moves inward along the body of the connecting sleeve 3. Since the side plate 704 on the inner side of the screw tube 701 is in contact with the baffle 6, during the inward movement of the screw tube 701, it will drive the side plate 704 to apply an inward pressure to the baffle 6. Since the baffle 6 is fixed on the fiberglass pipe, this pressure will be transmitted to the fiberglass pipe, causing the fiberglass pipe to tend to move towards the center of the connecting sleeve 3, further ensuring the tight contact between the fiberglass pipe and the annular rubber pad 4.

[0020] Simultaneously, the support plate 702 inside the spiral tube 701 moves together with the spiral tube 701, and the pressure plate 703 at the end of the support plate 702 gradually approaches and squeezes the rubber ring 5. Since the rubber ring 5 has a cavity, it will deform under the pressure of the pressure plate 703, filling the gap between the connecting sleeve 3 and the fiberglass pipe, enhancing the sealing effect. When the spiral tube 701 rotates to the appropriate position, it stops rotating. At this time, the first fiberglass pipe 1 and the second fiberglass pipe 2 achieve a stable and sealed connection under the joint action of the annular rubber pad 4, the rubber ring 5 and the pressure assembly, effectively preventing the medium (liquid or gas) flowing in the pipeline from leaking from the connection, and ensuring the normal operation of the pipeline system.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
