Abstract
The utility model discloses a self-rivet connected nodular cast iron pipe of large-diameter snap spring. A self-rivet connected nodular cast iron pipe of large-diameter snap spring comprises a muzzle bell and a faucet; an inner annular groove is arranged at an annular face at inner side of a sealing face of the muzzle bell; an outer annular groove is arranged at a faucet end of the faucet; the widths of the inner and outer annular grooves are identical; the faucet of one cast iron pipe is connected with the muzzle bell of another cast iron pipe; during connection, the outer annular groove at the faucet end of one cast iron pipe and the inner annular groove of the muzzle bell of another cast iron pipe are mouth-to-mouth; a snap spring is nested in the mouth-to-mouth outer annular groove of the faucet end of the cast iron pipe and the inner annular groove of the muzzle bell of another cast iron pipe; and the thickness of the snap spring is identical to the widths of the inner and outer annular grooves. The utility model is a self-rivet connected nodular cast iron pipe of large-diameter snap spring having the characteristics of simple construction and low constructional cost, and capable of realizing flow line production of nodular cast iron pipe.
Description
Technical field
The utility model relates to a kind of ductile iron pipe, especially a kind of heavy-calibre circlip self-rivet connecting ductile 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 in the utility model 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 technical scheme in the invention for solving the technical problem is:
A kind of heavy-calibre circlip self-rivet connecting ductile 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 interior annular groove, socket end at socket is provided with the outer ring groove, the width of interior annular groove and outer ring groove is suitable, the socket of a cast iron tube is connected with the bellmouth of another cast iron tube, when connecting, the interior annular groove of the outer ring groove of the socket end of a cast iron tube and the bellmouth of another cast iron tube mouth to mouth, in the interior annular groove of the bellmouth of the outer ring groove of the socket end of a mouth-to-mouth cast iron tube and another cast iron tube, be embedded with jump ring, the thickness of jump ring and above-mentioned in the width of annular groove and outer ring groove suitable.
The technical scheme in the invention for solving the technical problem can also be:
Annular groove and outer ring groove are " U " type groove in described in the utility model, and the cross section of described jump ring is a rectangle, and the internal diameter of jump ring is slightly larger than the diameter of the bottom land of outer ring groove, the diameter of the bottom land of annular groove in the external diameter of jump ring is slightly less than.
Compared with prior art, the utility model construction is simple, construction cost is low, and ductile iron pipe production can realize pipelining.
