The technical scheme in the invention for solving the technical problem is:
A kind of self-anchoring joint ductile iron pipe that baffle ring is installed, 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, be equipped with in the baffle ring groove baffle ring (6) 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 technical scheme in the invention for solving the technical problem can also be:
The sectional shape of baffle ring groove described in the utility model is that rectangle, trapezoidal, arc, band arc rectangle or band arc are trapezoidal, and the sectional shape of described baffle ring (6) is identical with the baffle ring groove.
The sectional shape of baffle ring groove described in the utility model 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 described in the utility model is that rectangle, trapezoidal, arc, band arc rectangle or band arc are trapezoidal.
Anchoring ring described in the utility model (4) forms or adopts built-up welding or welding manner to process for directly casting.
Baffle ring of the present utility model 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 beneficial effects of the utility model are:
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 utility model (installment state).
Fig. 2 is the plan view of Fig. 1.
Installation method of the present utility model:
If when producing cast tube, directly do not cast out anchoring ring 4, just need to adopt built-up welding or welding manner fixed processing anchoring ring 4 in the socket end appropriate location of cast tube earlier, again O-ring seal 3 is installed in the bellmouth of cast tube, the bellmouth of then the pipe socket being packed into encircles shelves 6 segmentations at last and packs into from mounting hole and get final product.
