Detailed Description
The following will further describe a plastic pipe for repairing continuously wound fiberglass reinforced plastic according to the present invention with reference to the accompanying drawings.
Referring to fig. 1 to 4, a plastic pipe for repairing, which is continuously wound with glass fiber reinforced plastics, includes pipe bodies 1 and sleeves 2 installed on the pipe bodies 1 for connection between the pipe bodies 1; the pipeline positioning device is characterized by also comprising a connecting and sealing structure 3 arranged on the sleeve 2 and a positioning structure 4 arranged on the pipeline body 1 and used for limiting the position of the pipeline body 1 in the sleeve 2; a metal sheet 5 is also pre-buried and mounted on one side of the sleeve 2; through the arrangement of the connecting and sealing structure 3, the connection effect is realized between the pipeline body 1 and the sleeve 2 through the reset force after the sealing ring 32 is extruded and the friction force between the pipeline body 1; through the arrangement of the positioning structure 4, the stroke of inserting one end of the pipeline body 1 into the sleeve 2 is limited, so that the phenomenon that the pipeline body 1 on one side is too long to be inserted, the inserting distance of the pipeline body 1 on the other side is short, and the connection firmness and the connection stability between the pipeline body 1 and the sleeve 2 are poor is avoided; through the pre-buried installation of the metal sheet 5 on one side of the sleeve 2, when the connected pipeline bodies 1 are jacked into an originally arranged pipeline, one side provided with the metal sheet 5 is positioned at the bottom, and the sleeve 2 rubs against the originally arranged pipeline inner wall when jacking in, so that even if the outer wall of the sleeve 2 is abraded due to friction, through the arrangement of the metal sheet 5, the problem that the outer wall of the sleeve 2 is damaged due to abrasion, the sealing cannot be realized, and even the connection between the sleeve 2 and the pipeline body 1 is disconnected is avoided; meanwhile, through the arrangement of the metal sheet 5, when the metal sheet 5 rubs with the originally arranged inner wall of the pipeline, the friction resistance is small.
Further, sheetmetal 5 is the arc setting, the installation of being convenient for, only need during pre-buried installation with it laminate sleeve 2 one side can, need not the suit, save the cost simultaneously.
Further, the connecting and sealing structure 3 comprises a plurality of sealing grooves 31 which are symmetrically arranged on the sleeve 2 and sealing rings 32 which are arranged on the sealing grooves 31; the installation position of the seal ring 32 is defined by the provision of the seal groove 31.
Further, the seal groove 31 is provided obliquely toward the outside of the sleeve 2; a plurality of dovetail grooves 33 are formed on the sealing ring 32; the sealing groove 31 is obliquely arranged towards the outer side of the sleeve 2, so that when the pipeline body 1 is inserted into the sleeve 2 and is contacted with the sealing ring 32, the sealing ring 32 is extruded in the continuous insertion overlong process of the pipeline body 1, and the thrust and extrusion force applied to the sealing ring 32 are blocked by the oblique arrangement of the sealing groove 31, so that the sealing ring 32 is prevented from being separated from the sealing groove 31 due to the thrust and extrusion force when the pipeline body 1 is inserted, and finally, the sealing function cannot be achieved and the connection and fixation effects cannot be achieved; through setting up a plurality of dovetail 33 on sealing washer 32 to make the sealing washer 32 top and pipeline body 1 contact site can be better produce deformation after receiving the extrusion, make the laminating of sealing washer 32 and pipeline body 1 tighter, sealed effect is better.
Further, the positioning structure 4 comprises a plurality of positioning blocks 41 which are arranged at two ends of the pipeline body 1 in an annular array by hot melting welding; the arrangement of the positioning blocks 41 limits the stroke of inserting one end of the pipeline body 1 into the sleeve 2, so that unstable installation and connection caused by excessive insertion or insufficient insertion amount are avoided; the bottom side of the pipeline body 1 is not provided with the positioning block 41, so that the positioning block 41 is prevented from interfering when the pipeline body 1 is pushed into an original laid pipeline, and meanwhile, when the pipeline body is installed, the side, provided with the metal sheet 5, of the sleeve 2 is the same as the side, not provided with the positioning block 41, of the pipeline body 1, and the pipeline body can also play a role in indication when the pipeline body 1 is pushed into the pipeline body; meanwhile, the other positioning blocks 41 on the pipeline body 1 are arranged to limit the rotation of the pipeline body 1, so that the pipeline body 1 is prevented from rotating when the pipeline body 1 is pushed into the sleeve 2, and one side of the sleeve 2, which is provided with the metal sheet 5, is not arranged at the bottom side.
Further, a cork pad 6 with a buffering function is further mounted at the end of the pipeline body 1 through glue; through the setting of cork pad 6, play the cushioning effect to the contact between pipeline body 1 and the pipeline body 1, avoid leading to producing the collision between pipeline body 1 and the pipeline body 1 because of the dynamics is overweight when inserting in inserting the sleeve 2 with pipeline body 1, lead to pipeline body 1 damaged.
The utility model discloses an installation: firstly, installing a sealing ring 32 in a sealing groove 31 of the sleeve 2, and installing a cork pad 6 at the end part of the pipeline body 1 by gluing; then, inserting one end of the pipeline body 1 into the sleeve 2, ensuring that one side of the sleeve 2 provided with the metal sheet 5 and one side of the pipeline body 1 not provided with the positioning block 41 are the same during insertion, completing installation of the pipeline body 1 on one side after the positioning block 41 is contacted with the end part of the sleeve 2 during insertion of the pipeline body 1, and then inserting the other pipeline body 1 into the other side of the sleeve 2 in the same way; after the plurality of pipeline bodies 1 and the plurality of sleeves 2 are connected, the connected plurality of pipeline bodies 1 are jacked into the originally laid pipeline, and when the pipeline bodies are jacked, one side, which is not provided with the positioning block 41, of the pipeline body 1 is the bottom side.
