Abstract
The utility model discloses a sealing gasket cover for a steel strip corrugated cut surface of a polyethylene steel strip enhanced thread double-wall corrugated pipe, wherein a sealing gasket cover body 1 covered the corrugated cut surface of the steel strip, the contact parts of the sealing gasket cover body 1 and the corrugated cut surface of the steel strip are coated with glue to be tightly combined together, a middle boss 2 is matched with the inner cavity of the corrugated cut surface of the steel strip, boss height 3 is clamped in the inner cavity of the corrugated cut surface of the steel strip to be positioned so as to prevent position shift, and the exposed steel strip section of the cut surface can be ensured to be not contacted with damp air, water and the like, thus preventing corrosion of the steel strip.
Description
Technical field
The utility model relates to the steel band ripple cut surface packing seal lid that a kind of polyethylene steel band strengthens the screw thread double-wall corrugated pipe.
Background technology
The polyethylene steel band enhancing screw thread double-wall corrugated pipe of producing and selling in the market is used for substituting traditional cement pipe and cast iron pipe, the pipe network that extensively applies to urban construction and engineering construction drain hose is laid, with its excellent performance and easily mounting means approved gradually by society.Machine is produced continuously when the polyethylene steel band strengthens the screw thread double-wall corrugated pipe and must be blocked by certain-length, be convenient to transport and install and use, steel band is done the skeleton of ripple has the steel band section to expose in air after sawed-off, for prevent to deposit with transport in the steel band section contact to get rusty with water or malaria and influence result of use, the method that adopts is a slice to be sealed on the steel band ripple cut surface greater than the polyethylene sheets of steel band ripple cut surface with the softening edge part greater than the reservation of the cut surface outside of electric calorifier blowing hot-air cut surface is wrapped, the connection place is closely not insecure yet, deposit with transport in play package action polyethylene sheets can infilter water with junction, steel band cross section or contact and draw up with damp air, come off, cause the corrosion of steel band cross section.Take away the polyethylene sheets of parcel during installation again, its steel band ripple cavity inside is mutual perforation on the whole piece pipe network circuit that links, the steel band cross section that has can be in contact with one another, and steel band is to be coated on the spiral lamination canoe to constitute a rule steel band long loop on the inner layer polyethylene wall, water flowed in pipe when pipe network used, the electronics that comprises in the water can form faint electric field when cutting the steel band coil, weak current, in the pipe network if any local steel band clad damaged or deposit with transportation in the steel band cross section phenomenon of corrosion takes place, can strengthen stretching of corrosion after the installation, the load bearing stength that corrosion increases the weight of to reduce pipe will have influence on product design and tenure of use.
The utility model content
The technical problems to be solved in the utility model provides a kind of steel band and strengthens the steel band ripple cut surface packing seal lid that uses when the screw thread double-wall corrugated pipe is produced, the permanent steel band cut surface that covers, block contacting of itself and water, air, prevent that steel frame gets rusty in the pipeline.
For addressing the above problem, steel band ripple cut surface packing seal lid of the present utility model, it is by being made up of the special-shaped level body of boss, the special-shaped level body profile of packing seal lid main body is identical with steel band ripple cut surface, the profile of middle part boss and the internal cavities of steel band ripple cut surface coincide, the height of boss snaps in the internal cavities of cut surface of steel band ripple and locatees, and prevents that the stressed position of packing seal lid main body from moving.It was coated assembly glue with steel band ripple cut surface contact portion and makes the two tight bond together when packing seal lid used, and two packing seal lid of pipe makes steel band ripple internal cavities be sealing state, avoids water and malaria to contact the generation corrosion with steel band.Pipeline is installed needn't take off the packing seal lid when connecting, filling out the hot-melt polyethylene sealing at place, the slit surfaces externally and internally of pipe alignment amalgamation connection back steel band ripple cements, make every segment pipe steel frame ripple internal cavities of installation independent sealed, reduce the phenomenon that produces faint electric field and weak current.
It is identical with steel band ripple cut surface to be as a kind of improvement of utility model that steel band ripple cut surface packing seal lid is the planar structure shape, the internal cavities that is distributed with annular boss and steel band ripple cut surface on the packing seal lid main body coincide, the height of annular boss snaps in and is used for the location in the internal cavities of steel band ripple cut surface, prevents that the position from moving.It was coated assembly glue with steel band ripple cut surface contact position and makes the two tight bond together when packing seal lid main body was used, and two packing seal of pipe covers and makes steel band ripple internal cavities be sealing state.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the transparent view of the utility model steel band ripple cut surface packing seal lid.
Fig. 2 is the cutaway view of the utility model steel band ripple cut surface packing seal lid A-A.
Fig. 3 covers the birds-eye view of another kind of embodiment for the utility model steel band ripple cut surface packing seal.
Fig. 4 is the cutaway view of the utility model steel band ripple cut surface packing seal lid B-B.
The specific embodiment
The transparent view of steel band ripple cut surface packing seal lid shown in Figure 1 and A-A cutaway view shown in Figure 2 are made up of packing seal lid main body 1 and boss 2 as can be known, the special-shaped level body profile of packing seal lid main body 1 is identical with steel band ripple cut surface, the external form of middle part boss 2 and the internal cavities of steel band ripple cut surface coincide, sealing during steel band packing seal lid main body 1 be coated with assembly glue with steel band ripple cut surface contact position the steel band cut surface tight bond of packing seal lid and polyethylene steel band enhancing screw thread double-wall corrugated pipe be in the same place, the height 3 of boss 2 snaps in the internal cavities of steel band ripple cut surface and locatees, prevent that packing seal from covering main body 1 position and moving, two of pipe makes steel band ripple internal cavities be sealing state with the packing seal lid.
From the another kind of embodiment birds-eye view of steel band ripple cut surface leak free shown in Figure 3 and B-B cutaway view shown in Figure 4 institute as can be known packing seal lid main body 1 be planar structure, shape is identical with steel band ripple cut surface, it is identical with the internal cavities of cut surface to be distributed with annular boss 4 on packing seal lid main body 1, sealing during steel band packing seal lid main body 1 be coated with assembly glue with the cut surface contact position steel band cut surface tight bond of packing seal lid and polyethylene steel band enhancing screw thread double-wall corrugated pipe be in the same place, the height 5 of annular boss 4 snaps in the internal cavities of steel band ripple cut surface and locatees, prevent that packing seal from covering main body 1 position and moving, two of pipe makes steel band ripple internal cavities be sealing state with the packing seal lid.
The utility model is not limited to the above-mentioned specific embodiment; as long as strengthen the method for the steel band ripple cut surface employing permanent closure of screw thread double-wall corrugated pipe at the polyethylene steel band; with the pad lid sealing steel band cutting section identical shaped with steel band ripple cut surface; no matter how the boss form changes, all drop within the protection domain of the present utility model.
