Abstract
The invention relates to a fiber reinforced plastic joint for marine discharge pipelines. The joint comprises adjusting nuts, two square tube reinforcing rings, circular retainers and long screw tie bolts. The inner sides of the square tube reinforcing rings are in contact connection with the circular retainers respectively and adjustably connected through the long screw tie bolts. When the joint is in service, the adjusting nut on one side is 5cm to 8cm away from the corresponding square tube reinforcing ring. The adjusting nuts, the square tube reinforcing rings and the long screw tie bolts are all made of steel with good wear resistance. The adjusting nuts, the square tube reinforcing rings and the long screw tie bolts are all made of the steel and can be replaced in various radiuses, and the different condition requirements are met. The circular retainers can be directly formed during the production of fiber reinforced plastic, and the application cost is reduced greatly. Applying the fiber reinforced plastic in long-range marine discharge pipeline projections is made possible.
Description
Technical field
The present invention relates to a kind of distance extra large pipeline of row joint used of growing.
Background technique
At present, arrange extra large pipeline material used both at home and abroad and comprise steel pipe, PE pipe and Glass Steel Tube.The electric welding docking that wherein steel pipe adopts, the heat-melting butt-joint that PE pipe adopts or electric melting sleeve docking, can make it effectively in the project construction of the extra large pipeline of the row of being used in.Yet the existing V shape that holds of Glass Steel Tube docks, and is easier to disconnect, so in the project construction of the extra large pipeline of the row of not being suitable for when being subject to axial tension.
Summary of the invention
The problems referred to above that exist in order to overcome the extra large pipe coupling of existing row, the invention provides a kind of glass fiber reinforced plastic sea disposal pipe joint.
The technical solution adopted for the present invention to solve the technical problems is: a kind of glass fiber reinforced plastic sea disposal pipe joint, by regulating nut, square tube stiffening ring, annular backer and long screw split bolt, formed, be characterized in: two square tube stiffening ring inner sides contact and connect annular backer respectively, pass through long screw split bolt and the adjustable connection of regulating nut between two square tube stiffening rings.
During use, between a side regulating nut and square tube stiffening ring, stay 5cm to the distance of 8cm.
Regulating nut, square tube stiffening ring and long screw split bolt process by the good iron and steel of wear resistance.
The invention has the beneficial effects as follows: regulating nut, square tube stiffening ring and long screw split bolt all adopt iron and steel processing, can change and can form various radiuses, meet different working condition requirements.Annular backer can directly form when Glass Steel Tube is produced, and greatly reduces user cost.Glass Steel Tube is applied in the extra large pipeline projects of long distance row and becomes possibility.
Accompanying drawing explanation
Fig. 1 is structure structure schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, glass fiber reinforced plastic sea disposal pipe joint of the present invention, comprises regulating nut 1, square tube stiffening ring 2, annular backer 3, long screw split bolt 4.
Two square tube stiffening ring 2 inner sides contact respectively and connect between 3, two square tube stiffening rings 2 of annular backer by long screw split bolt 4 and the adjustable connection of regulating nut 1.During use, between a side regulating nut 1 and square tube stiffening ring 2, stay 5cm to the distance of 8cm.Regulating nut 1, square tube stiffening ring 2 and long screw split bolt 4 process by the good iron and steel of wear resistance.
Regulating nut 1 adopts Two bors d's oeuveres nut spacing, limit in the axial direction the displacement of glass fibre reinforced plastics bell and spigot joint, prevent deviating from of bell and spigot joint, utilize nut gap simultaneously, can allow glass fibre reinforced plastics joint to produce within the specific limits knuckle, to reduce the line style rigidity in the extra large pipe laying process of row, so that the cable laying operation of the extra large pipeline of the row of completing.
Square tube stiffening ring 2 adopts Cold drawing square pipe clod washes processing, and intensity is high, be difficult for unstability; Fabricating cost is low, and precision is high, is easy to processing; Stiffening ring utilizes self tightening force in conjunction with glass fibre reinforced plastics annular backer acting in conjunction, and leading screw, the required axial tension of nut are provided; Stiffening ring corner rounding off, can be smooth and easy by construction planies such as the extra large pipeline launcher of row, pipe support racks.
Glass fibre reinforced plastics annular backer 3 applies system in processed glass steel pipe process, with low cost, process easy; For square stiffening ring provides force bearing point, provide leading screw, the required axial tension of nut.
Long screw split bolt 4 adopts Cr40 material long screw, and the stretching resistance of joint is provided; Adopt rolled thread processes, processing is convenient, and with low cost, quality of processing is good.
During use, first be regulating nut 1, purposes is to fix the square stiffening ring 2 of a side, and opposite side stays 5cm to the distance of 8cm, be convenient to pipeline and in movement in the radial direction, can also limit jointing and be subject to the angle forming after moment of flexure, make within it remains on safety range.Then be square tube stiffening ring 2, its predominant use is under the restriction of regulating nut 1, fixes two end tube sections and follows it and move together.Next be annular backer 3, purposes, for ease of the perfection docking of tube head, can also limit the distance between square tube stiffening ring simultaneously, in using, plays certain protective action in the later stage.Be finally long screw split bolt 4, purposes is connecting square pipes stiffening ring 2 and regulates long screw split bolt 4.
In using process, glass fibre reinforced plastics backer 3 adds and makes at frp pipe man-hour, and miscellaneous part completes installation at the construction field (site).According to the performance index requirement of laying technique and glass fibre reinforced plastics joint socket, regulating nut 1 position, can control joint and rotate within the specific limits, reaches the requirement of controlling pipe laying line style.
