Abstract
The invention discloses a pipe product connecting piece and applications thereof in the steel-plastic composite pipeline connection, wherein the connecting piece comprises buckling and pressing baffle rings, a metal cylinder, a seal ring and a flange; the buckling and pressing baffle ring is connected with the metal cylinder into a whole; and a metal buckling and pressing inner core ring is also corresponding to the metal cylinder. The applications of the connecting piece in the steel wire reinforced plastic composite pipe product connection are characterized in that the buckling and pressing baffle ring together with the metal cylinder and the metal buckling and pressing inner core ring are matched and locked tightly on the port of the steel wire reinforced plastic composite pipe product, the seal ring is arranged between the bucking and pressing baffle rings at end parts of two steel wire reinforced plastic composite pipes; then the steel wire reinforced plastic composite pipe products required to be connected are connected into a whole through the match of the flange and the bolt; and the pipe product connecting piece is especially applied to the connection of steel wire reinforced plastic composite pipe products with the caliber of phi 315mm or above. The connection mode can completely meet the connection of the steel wire reinforced plastic composite pipe product with the caliber of phi 315mm or above under the 2.0MPa using environment.
Description
Technical field
The present invention relates to conveyance conduit, be specially a kind of tube connection piece and the application in composite metal plastic pipe connects thereof, the steel filament reinforced plastics composite pipe that especially is suitable for Ф 315mm and above bore connects.
Background technique
At present, the connecting means of withholding of known steel filament reinforced plastics composite pipe is applicable to that mainly the following steel wire tube of Ф 250mm bore connects.The connecting means of Ф 315mm bore is that electric melting pipe fittings connects or thermofusible spigot connects, and just through iron flange dish, bolt, nut and sealing gasket two tubing is linked together.When this kind Placement is used under the 2.0MPa environment, because the creep properties of plastic pipe, the pipe fitting joint situation of leaking appears easily.
Summary of the invention
The objective of the invention is to overcome existing plastic tube link and connecting means defective, a kind of improved link and application thereof are provided, can satisfy the purpose that the steel filament reinforced plastics composite pipe of Ф 315mm and above bore uses under the 2.0MPa pressure environment.
The design proposal that the present invention taked is: a kind of tube connection piece; Comprise and withhold baffle ring, metal cylinder, seal ring, flange; Screw is arranged on the flange, it is characterized in that withholding baffle ring and metal cylinder is connected as a single entity, withhold on the periphery wall of steel filament reinforced plastics composite pipe end; Also have metal to withhold the inner core ring on the corresponding steel filament reinforced plastics composite pipe end inner peripheral wall; Seal ring is withheld between the baffle ring two joint steel filament reinforced plastics composite pipe ends, and flange is actively set on pipe shaft one side of withholding baffle ring, and bolt and nut connects between the two joint flanges.
Described metal cylinder is an iron sheet tube, and the inwall of tube has the ripple tooth, and it is steel ring that metal is withheld inner ring, and the steel ring outer wall has the ripple tooth.
The application of described a kind of tube connection piece in the steel filament reinforced plastics composite pipe connects; It is characterized in that to withhold baffle ring and withholding the inner core ring together with metal cylinder and described metal and lock on the port of said steel filament reinforced plastics composite pipe through withholding machine; Said seal ring places withholding between the baffle ring of two joint steel filament reinforced plastics composite pipe ends, cooperates with bolt through flange then the required steel filament reinforced plastics composite pipe that is connected is linked into an integrated entity.
Above-mentioned Placement is more suitable for the connection of the steel filament reinforced plastics composite pipe more than Ф 315mm bore.The connection of the highest pipeline applicable to nominal pressure 2.0Mpa.
Beneficial effect of the present invention: this kind Placement can satisfy the connection of steel filament reinforced plastics composite pipe under the above 2.0MPa Environmental Conditions of Ф 315mm bore fully.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the assembling schematic representation of embodiment of the invention Placement.
Among the figure, 1. steel filament reinforced plastics composite pipe, 2. metal cylinder, 3. flange, 4. seal ring, 5. bolt, 6. nut is 7. withheld baffle ring, 8. withholds inner core.
Embodiment
Embodiment: illustrated explanation Ф 315mm bore steel filament reinforced plastics composite pipe withhold the baffle ring Placement, two joint steel filament reinforced plastics composite pipes connect as one through this kind.During connection; To withhold baffle ring metal cylinder 2 earlier and withhold inner core 8 and be placed on steel filament reinforced plastics composite pipe 1 end; Lock it with the machine of withholding respectively at two ends, aligns the back at placement seal ring 4 tubing two ends and with bolt 5 two end flange 3 are connected, and nut 6 is compressed; Make and withhold baffle ring 7 and link together closely, realize that tubing connects with seal ring 4.
