Abstract
This utility model discloses a ball pivot universal pipe joint which is matched with a coal dust spraying gun to blow coal dust into a blast furnace of metallurgy, and a ''soft tube'' which is matched with coal dust spraying gun is composed of N ball pivot universal pipe joints. Both sides of the straight tube of each ball pivot universal pipe joint is provided with a ball pivot seat, a inner sealing ring is installed at the bottom of the cavity of ball pivot seat, the ball shape section of ball tube is installed in the inner cavity of ball pivot and closely connected with the inner sealing ring, an outer sealing ring is installed in the cavity of ball pivot which is closely connected with the ball shape section of ball tube; a compression nut sleeve is sleeved on the ball seat head after crossing the straight tube section of ball tube. The ''soft tube'' which is composed of N ball pivot universal pipe joints can fully replace a metal soft tube or a high pressure rubber tube used before. The operation is flexible, the use is convenient, and the operating rate of coal dust spraying gun can be enhanced; moreover, this utility model can be promoted to other industry as the connecting tube of transporting gas or liquid.
Description
Technical field
The utility model relates to a kind of tube coupling, relates in particular to a kind of spherical hinge universal tube coupling of matching with the coal spouting gun of spraying coal powder in the metallurgy high furnace stove of being applied to.
Background technique
Spraying coal powder is one of energy-saving and cost-reducing process means of present metallurgy high furnace in the metallurgy high furnace stove, what spraying coal powder used usually is the coal spouting gun of adjustable and retractable, the front end of coal spouting gun stretch into the blast-furnace tuyere inner chamber with coal dust in the air port sprays into State of Blast Furnace, and the rear end of coal spouting gun is normally with high-pressure rubber hose or metallic hose, with high-pressure rubber hose or metallic hose can realize with coal dust from the pulverized coal preparation workshop in coal spouting gun sprays into State of Blast Furnace, but its deficiency is: 1. high-pressure rubber hose uses inconvenient, operate dumb, high temperature resistant, abrasion resistance properties is poor, bursts the generation security incident easily; 2. the disadvantage of metallic hose is that working life short, changes the frequency height, influences the Coal powder spray operating rate.Be that high-pressure rubber hose or metallic hose all can't be adjusted needed angle, on-the-spot technological operation difficulty under high temperature liquid iron or high temperature furnace slag influence.This is a thorny problem that needs urgent solution again of present domestic metallurgy industry.
Summary of the invention
The purpose of this utility model is to provide a kind of ability high temperature life length, changes conveniently, and applied range can improve the alternative high-pressure rubber hose of complete energy of metallurgy high furnace coal powder injection operating rate or the spherical hinge universal tube coupling of metallic hose.
For realizing above-mentioned task, the technical solution adopted in the utility model is: the fixed ball pivot seat at two of a straight tube, inner chamber bottom at the ball pivot seat is laid inner seal ring, the spherical segment of bulb tube is movably arranged on the inner chamber of ball pivot seat and the spherical segment of bulb tube is contacted with inner seal ring, the outer seal ring that is placed in ball pivot seat inner chamber contacts with the spherical segment of bulb tube, and the straight length rear thread that gland nut passes bulb tube is sleeved on the termination of ball pivot seat.
The spherical hinge universal tube coupling that adopts as above technological scheme to provide compared with prior art can obtain following beneficial effect:
1. safety alternative high-pressure rubber hose or metallic hose is used for that spraying coal powder is with the connecting tube of coal spouting gun in the metallurgy high furnace stove, and easy to use, flexible operation improves and dusts operating rate 2-3 doubly, and the 1-2 that is equivalent to high-pressure rubber hose or metallic hose working life doubly;
2. described spherical hinge universal tube coupling not only can be used for also can be used as the connecting tube of conveying gas (as coal gas, oxygen etc.) or liquid (as water, wet goods) to metallurgy high furnace spraying coal powder connecting tube, practicable universal connection.
Description of drawings
Accompanying drawing is the structure cross-sectional schematic of spherical hinge universal tube coupling described in the utility model, also is Figure of abstract of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
A kind of spherical hinge universal tube coupling described in the utility model by straight tube 1, ball pivot seat 2, inner seal ring 3, outer seal ring 3 ', gland nut 4, bulb tube 5 constitute.Be consolidated with ball pivot seat 2 at two of straight tube 1, describedly fixedly select welding or spiral marking connection for use, and the length l of straight tube 1 〉=0 millimeter can be selected as the case may be.Inner chamber bottom at ball pivot seat 2 is laid inner seal ring 3, and inner seal ring 3 can select for use the rubber material to make.The spherical segment of bulb tube 5 is movably arranged on the inner chamber of ball pivot seat 2, in order to make bulb tube 5 freely rotate required angle at the inner chamber of ball pivot seat 2, realize universal function, the spherical segment diameter of bulb tube 5 is less than the intracavity diameter of ball pivot seat 2, be the sealing between the spherical segment that guarantees inner seal ring 3 and bulb tube 5 simultaneously, the spherical segment of accomplishing bulb tube 5 contacts with inner seal ring 3, and this contact needs to use the tight way of contact, so that spherical hinge universal tube coupling air tight (or powder) or no leakage when work.Outer seal ring 3 ' be installed in ball pivot seat 2 inner chambers also contacts with the spherical segment of bulb tube 5, is similarly the tight way of contact, and purpose is not leak.Gland nut 4 passes the termination that is sleeved on ball pivot seat 2 behind the straight length of bulb tube 5 and with outer seal ring 3 ' compress, suit mode the best is selected thread set for use, and wherein gland nut 4 termination that is sleeved on ball pivot seat 2 can be adopted gland nut 4 is sleeved on the inner chamber of ball pivot seat 2 terminations or the outer wall of ball pivot seat 2 terminations.
During enforcement, the individual spherical hinge universal tube coupling of N (integer of N 〉=1) linked with connecting body (connecing as pipe) constitute " flexible pipe " of the needed use that matches with coal spouting gun, because have (N+1) individual bulb tube 5 can make the connecting tube that " flexible pipe " becomes universal function on this " flexible pipe ", " flexible pipe " length can be determined as required.Operator operate this " flexible pipe " can implement coal-injection process easily, reaches purpose described in the utility model.Can pull down the spherical hinge universal tube coupling that any joint can not continue to use after using through the long period, or the inner seal ring in the spherical hinge universal tube coupling 3 or outer seal ring 3 ' or ball pivot pipe 5, load onto new can coming into operation again, can save used spare part.
Claims (2)
