Abstract
The utility model provides a metal hose with low resistance loss and high abrasion-resistance used for a blast furnace cooling wall. The utility model comprises connecting parts respectively arranged at the both ends, sleeve rings respectively arranged at the inner side ends of the two connecting parts, a mesh sleeve connected with the two sleeve rings, a corrugated pipe connected with the connecting parts and assembled in the mesh sleeve, and a lining tube with the low resistance loss and the high abrasion-resistance, wherein, the lining tube is formed by steel strips with S-shaped cross sections, connected with the connecting parts, and arranged at the both ends of the corrugated pipe according to an equal diameter spiral nesting and encircling method. Through the lining tube with the low resistance loss and the high abrasion-resistance assembled in the metal corrugated pipe, the utility model effectively solves the problems of the connecting hose of a blast furnace water cooling system that the resistance loss is high, the flow quantity is insufficient, and the service life is short.
Description
Technical field
The utility model relates to a kind of blast furnace cooling stave low-resistance that is used for and decreases the high abrasion metallic hose.
Background technology
At present, the adjacent water-cooled tube of metallurgy high furnace water cooling wall adopts sebific duct or corrugated flexible metal tube to connect usually.Because mounting distance is shorter, utilize sebific duct to connect, bending radius is not enough, and ellipse is forced to become in the sebific duct cross section, and constriction in flow area influence the flow of water coolant, cooling performance reduction.Adopt metallic hose to connect and can avoid connecting the problem that occurs with sebific duct, but because the metallic hose inwall is a washmarking, produce turbulent flow during flow of cooling water, resistance is decreased bigger.In addition, the wall thickness of metallic hose is very thin, often contains anvil cinder in the water coolant, causes the wearing and tearing to pipe easily, reduction of service life.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of bending radius little, can not produce turbulent flow during flow of cooling water, and resistance is decreased little, and the blast furnace cooling stave low-resistance that is used for of long service life is decreased the high abrasion metallic hose.
The technical scheme that realizes above-mentioned purpose is: a kind of blast furnace cooling stave low-resistance that is used for is decreased the high abrasion metallic hose, it includes the connection portion that is arranged at two ends respectively, medial extremity in two connection portions disposes the collar respectively, be connected with two collars and be provided with net, being connected with the connection portion in net is equipped with corrugated tube, in corrugated tube two ends be connected with the connection portion respectively be equipped with by the S-shaped steel band in cross section by isometrical spiral nested rings around and the low-resistance that constitutes is decreased the high abrasion bushing pipe.
The utility model decreases the high abrasion bushing pipe by assembling low-resistance in metallic bellows, effectively solved blast furnace water-cooling but system's resistance of connecting flexible pipe decrease big, underfed and work-ing life short problem.
Description of drawings
Fig. 1 originally is used for the blast furnace cooling stave low-resistance to decrease high abrasion metallic hose structure master sectional view.
Fig. 2 is Fig. 1 partial enlarged drawing.
Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described.
As accompanying drawing, originally be used for blast furnace cooling stave low-resistance damage high abrasion metallic hose and include the connection portion of forming by nut 1 fitted seal pad, 8 jointings 7 and terminal pad 2, medial extremity in the connection portion has the collar 4 through the welding fixed configurations on terminal pad 2, the collar 4 is through being welded to connect net 5, in net 5, be weldingly connected and be equipped with corrugated tube 6 with terminal pad 2, the inboard that two ends are fixedly welded on terminal pad 2 respectively in corrugated tube 6 in be provided with the steel band that is straight flange S shape by the cross section by isometrical spiral nested rings around and the low-resistance damage high abrasion bushing pipe 3 that constitutes.
As accompanying drawing embodiment, this low-resistance is decreased the high abrasion metallic hose and is provided with exhaust nozzle 9 in the terminal pad 2 of an end.
It is an embodiment of the present utility model that the low-resistance that accompanying drawing provides is decreased high abrasion metallic hose structure.This low-resistance decrease high abrasion metallic hose connection portion structure can according to blast furnace water-cooling but the configuration requirement of system change.Its structural changes belongs to prior art, does not give unnecessary details.
