Abstract
The utility model relates to a gas shield for sealing the ends of steel plastic compound pipes, comprising an inside gas shield and an outside gas shield. The inside gas shield with a cavity is in a cylinder shape, comprising an inflating valve 1, the outside surface of a column jacket 2, a cavity air chamber 3, an upper end-face 4, and a floor 5. The outside gas shield is in a cylinder shape with a cavity air chamber in the cylinder wall, which comprises an inflating valve 7, an annular cylindrical air chamber 8, the medial surface of the cylinder 11, the lateral surface of the cylinder with a reinforcement layer in the outside 13, an upper end-face 9, and a floor 10. The utility model relates to the gas shield for sealing end which is made up of flexible material, and used to seal the ends of composite pipes. The ends of the composite pipe are clamped between the inside gas shield and the outside gas shield. After being aerated, sealing of the ends of the composite pipe can be auto completed by heating the composite pipe. Not only the efficiency can be improved, but also the quality of sealing can be improved by adopting the utility model.
Description
Technical field
The utility model relates to a kind of gas bag that is used for port sealing after the steel-plastic composite pipe cutting.
Background technique
In the production process of steel-plastic composite pipe, generally produce the long steel-plastic composite pipe of length earlier, and then length is as required cut.After the cutting, will expose the Steel Skeleton of interlayer in the port of steel-plastic composite pipe, Steel Skeleton is exposed in the air easily that burn into gets rusty, thereby influences the working life of steel-plastic composite pipe,, must the port of steel-plastic composite pipe be sealed again for this reason.Prior art generally adopts injection molding machine of plastic to finish sealing of steel-plastic composite pipe, this method operating time is long, efficient is low, also be not easy to site operation, and the end face that seals is smooth inadequately, smooth, need carry out manual amendment, especially the plastics of quadric injection mould connect not firm, the port plastics come off easily, and can't construct in the erecting bed.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of port sealing simple, that can make steel-plastic composite pipe the smooth smooth gas bag that is used for the steel-plastic composite pipe port sealing.
The technical solution of the utility model is design like this: a kind of gas bag that is used for the steel-plastic composite pipe port sealing, be characterized in: it is made of interior gas bag and outer gas bag, interior gas bag is cylindric, be provided with cavity in it, it comprises valve cock 1, interior gas bag outer cylinder 2, cavity air chamber 3, upper-end surface 4, bottom surface 5; Outer gas bag is cylindric, is provided with the cavity air chamber in barrel, and it comprises that valve cock 7, annulus cylindricality air chamber 8, cylinder inner side surface 11, skin have cylinder outer side surface 13, upper-end surface 9, the bottom surface 10 of reinforced layer.
Elder generation inserts the interior gas bag of this device in the steel-plastic composite pipe during use, again outer gas bag is enclosed within the steel-plastic composite pipe port, and charge into pressurized air respectively, raise by the temperature of thermatron the steel-plastic composite pipe mouth of pipe, make the compound inside and outside plastic layer of steel-plastic composite pipe softening, by the extruding of gas bag, the port of the plastic flows steel-plastic composite pipe after softening, thus realization is to the sealing of the exposed Steel Skeleton of steel-plastic composite pipe port.The utility model can guarantee that the composite plastic layer of steel-plastic composite pipe port envelopes exposed Steel Skeleton equably under heating status, under the extruding of gas bag, and the cooling rear port is smooth, smooth, need not manually row finishing again, and product is light.

Embodiment
The utility model is made of interior gas bag and outer gas bag, and by Fig. 1, Fig. 2 as seen: gas bag is cylindric in of the present utility model, is provided with cavity in it, and it comprises valve cock 1, interior gas bag outer cylinder 2, cavity air chamber 3, upper-end surface 4, bottom surface 5.Valve cock 1 is located on the upper-end surface 4, and for the resistance to high temperature that improves gas bag can put elastic overcoat 6 outside the outer cylinder 2 of interior gas bag, the cavity cross-section of air chamber 3 can be rectangle, also can be ellipse.
By Fig. 3, Fig. 4 as seen: outer gas bag of the present utility model is cylindric, is provided with the cavity air chamber in barrel, and it comprises that valve cock 7, annulus cylindricality air chamber 8, cylinder inner side surface 11, skin have cylinder outer side surface 13, upper-end surface 9, the bottom surface 10 of reinforced layer.Be the resistance to high temperature that improves outer gas bag tubular resilient bushing 12 on inboard cylinder 11 liners of cylinder of gas bag outside.
By Fig. 5, Fig. 6 as seen, earlier high temperature resistant elastic overcoat 6 of the present utility model is set to outside the interior gas bag outer cylinder 2, again high temperature resistant nonmetal ring set 14 is placed in high temperature resistant elastic overcoat 6 outer upper end portions, and then be inserted in the steel-plastic composite pipe, after in the extremely outer gas bag cylinder inner side surface 11 of outer gas bag resilient bushing 12 linings, again its integral body is enclosed within on the outer wall of steel-plastic composite pipe, then pressurized air is charged into air chamber 3 and air chamber 8 respectively by valve cock 1, valve cock 7.Utilize heating equipment to make the composite plastic layer of steel-plastic composite pipe inside and outside wall softening,, make the port of softening plastic flow, thereby reach the purpose of sealing to steel-plastic composite pipe through the extruding of air bag compressed air.
