Abstract
The invention relates to a pipeline interface structure, in particular to an interface structure of a ductileiron pipe. A baffle ring mounting groove and a sealing ring mounting groove are arranged on the inner cylindrical surface of a bellmouth of the ductileiron pipe, and a sealing ring is embedded in the sealing ring mounting groove. An anchoring ring is arranged on the outer cylindrical surface of a socket and is positioned between the baffle ring mounting groove and the sealing ring mounting groove a well as is close to the baffle ring mounting groove. A baffle ring mounting hole is arranged on the end face of the socket and communicated with the baffle ring mounting groove, and a baffle ring is embedded in the baffle ring mounting groove from the baffle ring mounting hole, wherein the right end face of the baffle ring is abutted against the anchoring ring, and the left end face is abutted against the left ring surface of the baffle ring mounting groove. The interface structure of a ductileiron pipe has simple structure and firm connection and can be suitable for pipelines with various calibers and pressures.
Description
Technical field
The present invention relates to a kind of interface structure of pipe joint structure, particularly ductile iron pipe.
Background technique
At present, in the 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 in the joint outside, the bell of pipe and socket are linked together.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.
Summary of the invention:
In order to overcome the shortcoming of prior art, the invention provides a kind of interface structure of ductile iron pipe, it is simple in structure, is connected firmly, applicable to the pipeline of various bores, various pressure.
The present invention solves the technological scheme that its technical problem takes: baffle ring mounting groove and seal ring mounting groove are arranged on the inner cylindrical surface of the bellmouth of ductile iron pipe, be embedded with seal ring in the seal ring mounting groove, the anchoring ring is arranged on the socket external cylindrical surface, the anchoring ring is between baffle ring mounting groove and seal ring mounting groove, near the baffle ring mounting groove, the baffle ring mounting hole is arranged on the bellmouth end face, the baffle ring mounting hole communicates with the baffle ring mounting groove, be embedded with baffle ring from the baffle ring mounting hole in the baffle ring mounting groove, the right side of baffle ring is near described anchoring ring, and the left side is near the left anchor ring of baffle ring mounting groove.
Described baffle ring mounting groove and seal ring mounting groove are casting groove or machining groove.
Anchoring ring on the described socket external cylindrical surface is casting ring or welding ring.
The rarest 3 the baffle ring pieces of described baffle ring are formed, and the length L of baffle ring piece is greater than the thickness H of baffle ring, and the baffle ring piece is independent separately; Described baffle ring mounting hole has one.
The rarest 3 the baffle ring pieces of described baffle ring are formed, and the length L of baffle ring piece connects with flexibility or rigidity between each baffle ring piece greater than the thickness H of baffle ring, and the quantity of described baffle ring mounting hole and position are corresponding with the baffle ring piece.
Described baffle ring mounting hole tamps with packing, and the baffle ring piece can not be skidded off from mounting hole.
Described baffle ring piece is screwed on bellmouth or 2 at baffle ring mounting hole place is linked together with upper baffle ring piece rigidity, and the baffle ring piece can not be skidded off from mounting hole.
The present invention is simple in structure, is connected firmly, applicable to the pipeline of various bores, various pressure.
