Abstract
The utility model relates to a fast joint for oxygen blowing pipes. The utility model comprises a joint body sleeve pipe 1, an elastic sealing ring 2 and a fastening nut 3. The interior of the joint body sleeve pipe is provided with a positioning table 4. The two heads of the joint body sleeve pipe are provided with external screw threads which are connected with internal screw threads of the fastening nut 3. The two end parts of the joint body sleeve pipe are provided with staircase bosses 5. The sealing ring 2 is a circular ring, and the longitudinal section of the circular ring is concave. A groove of the sealing ring is embedded with staircase bosses of the end parts of the joint body sleeve pipe. The internal diameter of the sealing ring is same with the outer diameters of connected oxygen blowing pipes 6 and 7. The external diameter of the sealing ring is same with the inner diameter of the fastening nut. When in connecting, two oxygen pipes are penetrated into the two heads of the joint body sleeve pipe and are sheathed in the sealing ring, and the fastening nut are screwed and fastened. The utility model has the advantages of light weight, low cost, no disengagement, no air leakage, and weld joint and waste of the oxygen blowing pipe saving.
Description
The utility model belongs to ironmaking, the preceding effective coupling head of oxygen blast of steel making furnace.
The connection of the oxygen lance of using before ironmaking, the steel making furnace is manual welding for a long time.Oxygen lance belongs to the normal consumption material of production, consumption is big, workman's field welding amount of labour is very big.Because of stokehold temperature height, when oxygen lance uses 4 meters left and right sides, just can't use, remaining pipe has just abandoned, and has nearly 1/3 oxygen blow steel pipe to abandon, and waste is big.
The purpose of this utility model provides the fast Quick connecting joint of a kind of novel oxygen lance.With this fast Quick connecting joint two oxygen lances securely are linked together, need not weld, when an oxygen blast seamless steel pipe burns 4 meters left and right sides, in time connect next root seamless steel pipe with this joint and use, constantly connect and use, easy and simple to handle, Security is good.
The fast Quick connecting joint of this oxygen lance, comprise the adapter body sleeve pipe, elastic seal ring, tightening nut, positioning table is arranged in the middle of in the adapter body sleeve pipe, two has the internal thread of outside thread and tightening nut to match, and there is the stepped shaft boss at adapter body sleeve pipe two end part, and seal ring is that the longitudinal section is groove and the adapter body cannula tip ladder boss scarf mutually of annulus, the seal ring of concave shape, the internal diameter of seal ring is identical with coupled oxygen lance external diameter, and external diameter is identical with the tightening nut internal diameter.
Ironmaking, the oxygen lance before the steel making furnace, ", 1/2 " seamless steel pipe normally 3/8, the adapter body of this fast Quick connecting joint is overlapped effective A3 materials processing and is become, and long 100-120mm, fastening piece are special-purpose hexagon nut or round end knurled nut.
When connecting two oxygen lances with this fast Quick connecting joint, two seamless steel pipes are penetrated adapter body sleeve pipe two ends respectively, pack into seal ring, fastening nut is fastening can be used.
This oxygen lance joint, in light weight, low price, available it constantly connect oxygen lance, do not throw off after connecting, air tight.So can not lose when long using about 4 meters, no wasting phenomena also can be stopped the welded pipe phenomenon that the welding part fractures when carrying, lifting, use, can save nearly 1/3 oxygen lance in 1 year, save a large amount of welding consumabless, alleviated workpeople's labor intensity.
Exemplary construction of the present utility model is provided by accompanying drawing.
Fig. 1 is the schematic representation that connects two pipes according to the fast Quick connecting joint of oxygen lance that the utility model proposes
Fig. 2 is the adapter body sleeve structure figure of this fast Quick connecting joint
Fig. 3 is the ring structure figure of this fast Quick connecting joint
Fig. 4 is a kind of circular annular knurl tightening nut structural drawing of this fast Quick connecting joint.
The fast Quick connecting joint of diagram oxygen lance comprises main casing body 1, O-ring seal 2, tightening nut 3, adapter body is overlapped effective 30 * 5mm seamless steel pipe and is processed into, long 100-120mm, leave a positioning table 4 in the middle of in its sleeve pipe, the sleeve pipe two end part are processed with ladder boss 5, outside car has the screw thread that matches with tightening nut, O-ring seal 2 is annulars, the longitudinal section of ring is a concave shape, the annular groove of O-ring seal and adapter body sleeve pipe two ends boss 5 be scarf mutually, the internal diameter of O-ring seal and coupled oxygen lance 6,7 external diameter is identical, and external diameter is identical with the internal diameter of tightening nut.
When connecting with this coupling head, " the weldless tube steel penetrates to positioning table 4 at two of adapter body sleeve pipe 1 respectively, packs into O-ring seal 2, tightens solid nut 3 fastening can uses, does not throw off during oxygen blast, and is air tight with two 1/2.The oxygen lance of such connection and coupling head are when oxygen blast, with the same can the burning gradually of oxygen hose of seamless steel pipe.
