Abstract
The invention discloses a modular cast iron tube of a self-anchoring joint and a baffle ring for installation, comprising a mouth and a socket of a tube body. An anchoring ring is arranged on the outer surface of the socket of the tube body; an anchoring annular slot and a baffle ring slot communicated with each other are arranged at the outside of a ladder-lip-shaped rubber ring slot of a mouthing inner cavity of the tube body; the distance between the anchoring ring and the cross section of the socket of the tube body corresponds to the anchoring annular slot of the mouthing inner cavity ofthe tube body when being inserted into the mouth of the tube body based on a specified length; and the mouthing body at the baffle ring slot is provided with a skylight-type baffle ring mounting holehaving a length greater than or equal to the maximum chord length of a baffle ring. The invention provides a modular cast iron tube of a self-anchoring interface improving the modular cast iron tube of high-pressure wide bore.
Description
Technical field
The present invention relates to a kind of ductile iron pipe, especially a kind of self-anchoring joint ductile iron pipe and installation baffle ring thereof.
Background technique
At present, existing ductile iron pipe self-anchoring joint design interface has dual mode from the anchor-hold source: the one, be embedded in anchor block at cushion rubber; The 2nd, utilize mechanical structures such as differential and bolt that the bell of pipe and socket are linked together in the joint outside.First kind is applicable to small-bore cast tube, and middle heavy caliber cast tube ovality is also bigger from anchor-hold than big and needs, adopt this kind structure unreliable, and anchor block has damage to cast tube; Second kind of structure is complicated, and is subjected to annex and structural limitations thereof from anchor-hold, generally is used for the mesolow pipeline.Therefore designing a kind of self-anchoring joint ductile iron pipe and installation thereof that is used for the high-pressure large-caliber ductile iron pipe and use baffle ring, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides a kind of self-anchoring joint ductile iron pipe installation baffle ring that is used for the high-pressure large-caliber ductile iron pipe.
The technological scheme that the present invention solves its technical problem is:
A kind of self-anchoring joint ductile iron pipe, the bellmouth and the socket that comprise body, outer surface at the socket of body is provided with the anchoring ring, outer installment at the terraced lip aprons slot of the bellmouth inner chamber of body has anchoring annular groove and the baffle ring groove that is interconnected, the anchoring ring apart from the distance of the section of the socket of body the socket end of body when length injects in the bellmouth of body in accordance with regulations the anchoring annular groove with the bellmouth inner chamber of body corresponding, baffle ring groove place bellmouth body is provided with sun-roof baffle ring mounting hole, and the length of baffle ring mounting hole is more than or equal to the maximum chord length of a baffle ring.
The technological scheme that the present invention solves its technical problem can also be:
The sectional shape of baffle ring groove of the present invention is that rectangle, trapezoidal, arc, band arc rectangle or band arc are trapezoidal.
The sectional shape of baffle ring groove of the present invention is trapezoidal, and trapezoidal outer hypotenuse and the angle between the body center line are 10 degree-100 degree.
The sectional shape of anchoring annular groove of the present invention is that rectangle, trapezoidal, arc, band arc rectangle or band arc are trapezoidal.
Anchoring ring of the present invention (4) forms or adopts built-up welding or welding manner to process for directly casting.
Baffle ring of the present invention is the fan-shaped assemblying body of polylith, polylith is fan-shaped after being combined into is a complete circle baffle ring, the sectional shape coupling of the baffle ring groove of the sectional shape of baffle ring and self-anchoring joint ductile iron pipe, the maximum chord length of every baffle ring is smaller or equal to the length of the baffle ring mounting hole of self-anchoring joint ductile iron pipe.
The invention has the beneficial effects as follows:
Filled up the blank of the self-anchoring joint ductile iron pipe that is used for the high-pressure large-caliber ductile iron pipe.
Description of drawings
Fig. 1 is structural representation of the present invention (installment state).
