Abstract
The utility model relates to a connecting device of big-caliber fiber reinforced plastic pipes, which comprises the fiber reinforced plastic pipes and a connecting pipe for connecting the two fiber reinforced plastic pipes, wherein joints are arranged at both ends of the fiber reinforced plastic pipes; bell mouths are arranged at two ends of the connecting pipe; annular convex layers are arranged on the joints; more than one groove is formed on the annular convex layers; bell mouth grooves corresponding to the location of the grooves are formed on bores of the bell mouths; inclined through holes penetrating through the wall of the connecting pipe are formed on the bell mouth grooves; locking keys are inserted between the grooves and the bell mouth grooves through the inclined through holes; and more than one sealing groove is formed at the front end of the annular convex layers of the joints. The connecting device has the beneficial effects that the structure is simple; the locking keys inserted between the grooves and the bell mouth grooves enables the fiber reinforced plastic pipes to be firmly connected with the connecting pipe, which achieves the sealing purpose, and also solves the connectivity of the high-pressure fiber reinforced plastic pipes. The connecting device allows installation of the fiber reinforced plastic pipes to be convenient and quick.
Description
Technical field
The utility model relates to the assembling pipe joint technical field, especially relates to a kind of connection set of heavy-caliber fiber reinforced plastic pipe.
Background technique
At present, fiber reinforced plastic pipe is in the field extensive use such as industrial, civilian, main body is used for the conveying of fluid, but known fiber reinforced plastic pipe joint and seal form has: flanged ends face, the bonding connection of socket joint and sealing, the sealing of socket joint O type circle, API screw thread and seal gease are tightly connected.All there is the pressure rating joint dimension in above-mentioned Connecting format or the narrow limitation of effect is installed, when being applied to pressure greater than 1.8MPa, pipe diameter during greater than 300 millimeters fiber reinforced plastic pipe, because thrust load is large, then can causes the loosening or pull-off of joint, thereby cause the leakage of pipeline.
Therefore, a kind of appearance of the connection set that can solve heavy caliber high pressure fiber reinforced plastic pipe sealing reliability and installation efficiency problem is necessary.
The model utility content
The utility model is to provide a kind of connection set that can solve heavy caliber high pressure fiber reinforced plastic pipe sealing reliability and installation efficiency problem for solving the problems of the technologies described above.
