Abstract
The invention discloses a heavy-calibre self-riveting connecting nodular cast iron pipe, which comprises a socket and a spigot. An annular groove is arranged on the annular surface of the inner side of the sealing surface of the socket; the spigot end of the spigot is provided with a self-riveting hole; a self-riveting nail is arranged in the self-riveting hole; and the diameter of the self-riveting nail is slightly less than the width of the annular groove. The invention is the heavy-calibre self-riveting connecting nodular cast iron pipe which has simple construction and low construction cost and can realize the flow line production of nodular cast iron pipe.
Description
Technical field
The present invention relates to a kind of ductile iron pipe, especially a kind of heavy-calibre self-riveting connecting nodular cast iron pipe.
Background technique
At present when producing self-riveting heavy caliber ductile iron pipe, owing to must add one week of weldering along the circumferential direction by hand near pipe socket end from the riveting ring, cause in actual production, be subjected to very big influence at aspects such as grinding tool, technology, equipment, production can not have good continuity, also is difficult to realize production line production.And in installation, each joint socket position also needs to excavate the construction hole, also wants the very high lock ring of user cost, pressing flange disk, j-bolt.Thereby manufacture cost and construction cost are all very high.Therefore, designing that a kind of construction is simple, construction cost is low, can realize the heavy-calibre self-riveting connecting nodular cast iron pipe that production line is produced, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of construction is simple, construction cost is low, can realize the heavy-calibre self-riveting connecting nodular cast iron pipe that production line is produced.
The technological scheme that the present invention solves its technical problem is:
A kind of heavy-calibre self-riveting connecting nodular cast iron pipe, the bellmouth and the socket that comprise it, the ring surface of the inboard of the sealing surface of bellmouth is provided with annular groove, socket end at socket is provided with from rivet hole, in rivet hole, be provided with from rivet, be slightly less than the width of annular groove from the diameter of rivet, described is unthreaded hole from rivet hole, in the bellmouth of bellmouth, be set with from the riveting ring, on the riveting ring, having from rivet hole, be screw hole from rivet hole on the riveting ring, described is screw from rivet, and the diameter of screw is identical with the diameter of screw hole.
The technological scheme that the present invention solves its technical problem can also be:
Annular groove of the present invention is the multiple tracks annular groove that distributes along its length, described from rivet hole be the multiple tracks of distribution along its length from rivet hole, every twice equate from the size of the centre distance between the centre distance between the rivet hole and the every bipassage ring connected in star.
Of the present invention is tapped hole from rivet hole, and described is screw from rivet.
Of the present invention is unthreaded hole from rivet hole, in the bellmouth of bellmouth, be set with a plurality of " U " type plug-in unit, the end of socket is inserted in " U " type groove of " U " plug-in unit, the inwall unthreaded hole from the same diameter of rivet hole with socket (4) socket end is arranged on the inwall of " U " type plug-in unit, on the outer wall of " U " type plug-in unit, have with from the identical outer wall thread hole of the diameter of thread of rivet, the outer wall thread hole is concentric with the inwall unthreaded hole, and the size of the centre distance between the centre distance of every twice outer wall thread hole and inwall unthreaded hole and the every bipassage ring connected in star equates.
Having from rivet hole of each road of the present invention is a plurality of, a plurality ofly evenly distributes along circumference from rivet hole.
Compared with prior art, the present invention constructs simply, construction cost is low, and ductile iron pipe production can realize pipelining.
