Description
Technical field
The invention belongs to draining blowdown pipeline field, more particularly to the spiral bar liner transition piece of a kind of carat of pipe.
Background technology
At present, the heavy caliber pipe of domestic production --- HDPE enhances hollow spiral tube（Type B）, abbreviation carat pipe.Its
The head and end of liner bellows is all that the extrusion cladding material freely with its periphery combines in peripheral spiral bar, causes product should
Locate appearance warpage sometimes, stay sometimes, and also material is few sometimes for clad, material is more sometimes, so product has poor appearance, matter herein
The defects of amount is poor, intensity is not high and unstable, so, existing product herein suddenly wait to improve by insufficient place.
The content of the invention
This patent product is at least one defect overcome described in the above-mentioned prior art, provides the spiral bar of a kind of carat of pipe
Liner transition piece, it is simple in structure, novel which has many advantages, such as, dimensionally stable and production are quick, it is outer with carat pipe
After enclosing in muscle the connection use of liner bellows, the peripheral spiral bar head and end of carat pipe is smooth, appearance is good.
The technical scheme is that：A kind of spiral bar liner transition piece of carat of pipe, wherein, including centrum, the vertebra
The big one end of body bore is equipped with socket, and the socket is elastic socket, and the outer surface of the transition piece is equipped with staggeredly clearly demarcated blind slot,
The transition piece is attached using the liner bellows of socket and the spiral bar head and end of carat pipe periphery.
The liner transition piece is made of cone and socket two parts；Its entire outer surface is equipped with staggeredly clearly demarcated blind slot, makes
The liner transition piece can be along the free bend of 360 degree of axis direction of rotation, and intensity is high；Its cone structure can be the outer of carat pipe
The liner bellows for enclosing spiral bar head and end distinguishes ascending and descending reasonable transition, utilizes socket and carat pipe
The connection of peripheral spiral bar liner bellows, make that first and last spiral bar both ends are smooth, appearance is good；The product structure is simple, novel, ruler
Very little stabilization and production are quick.
Further, the bottom periphery of socket is equipped with holding groove.Holding groove enables the liner bellows of socket and spiral bar fast
Speed is located by connecting.
Further, the outer wall of socket is equipped with convex ribs.Convex ribs make the connection increase friction of the liner bellows of socket and spiral bar
Power, convex ribs coordinate the liner bellows /V to spiral bar with holding groove, and transition piece is made to keep stable connection with spiral bar.
Further, socket is additionally provided with notch.Because notch makes socket have elastic characteristic, when socket and carat pipe periphery spiral
During the liner bellows connection cooperation of muscle, the end of socket because notch gap can stress become smaller, and sprung back after coordinating in place
It resets, installation connection is quick and easy, and reliability is high, is completely embedded.
Further, blind slot is waist type groove.Waist type groove is equipped on centrum, enables the liner transition piece real under some strength
Freely, flexibility is more preferable for now bending.
Further, a layered material layer is equipped in blind slot.The bed of material within the specific limits can with the bending of transition piece and internal layer receive
Contracting, outer elongate keep the draftability and flexibility of centrum.
Further, which is injection molding.Injection molding makes the transition piece quality good, and production is quick.
The beneficial effects of the invention are as follows：
1st, the liner transition piece is made of cone and socket two parts, and entire outer surface is equipped with staggeredly clearly demarcated waist type blind slot,
And formed by injection molding, make the liner transition piece can be along the free bend of 360 degree of axis direction of rotation, intensity is high；Its cone
Structure, can be the peripheral spiral bar head and end of carat pipe liner bellows distinguish it is ascending and descending reasonable
Transition is connected using socket with the peripheral spiral bar liner bellows of carat pipe, makes that first and last spiral bar both ends are smooth, appearance is good；
The product structure is simple, novel, and dimensionally stable and production are quick.
2nd, the socket of the liner transition piece is elastic socket, and a certain number of notches and convex ribs are not only distributed in it, and
Its bottom periphery is additionally provided with holding groove.After coordinating /V by the convex ribs and holding groove of socket, the liner ripple of socket and spiral bar
Line pipe both ends can be located by connecting rapidly, convenient and reliable.
3rd, relatively thin layered material layer is designed with below the waist type blind slot of the transition piece, which within the specific limits can be with transition
The bending of part and internal layer is shunk, outer elongate, make that product bending degree of freedom is high, structure novel.
