Abstract
The utility model relates to a fast assembled joint for sealing oxygen blast pipe of electric furnace. The joint belongs to an equipment for smelting kiln and smelting oxygen blowing, mainly comprising a rotating external sleeve, a sealing fastening core, a screwed snap ring, and a special sealing rubber ring, wherein, an oxygen joint pipe can be sealed by the screwed snap ring; oxygen blowing lance can be sealed by the sealing fastening core and the special sealing rubber ring, and a sealing system is formed. The utility model has the advantages of convenient operation, rapid pipe connection, good sealability, simple structure and low cost.
Description
The utility model is an oxygen blast of electric furnace seal of tube ready-packaged joint.
In steel manufacture process, constantly too busy to get away oxygen and relevant various oxygen equipment and the devices used particularly at steel works, all consume a large amount of oxygen every day, with in the oxygen, leak loss seriously owing to joint does not sternly cause oxygen.Employed oxygen lance consumption is big in Electrosmelting Of Steel is produced, change frequent, take over oxygen lance joint at oxygen more and to adopt a kind of rubber sleeve pipes and greater than one section short tube of oxygen lance, oxygen lance is inserted in the short tube, the joint rubber sleeve seal of tube, fixing with the iron wire binding, do not reach desirable seal degree so far away, at the position that is connected, the phenomenon of a large amount of oxygen often appears leaking, the loss in vain of nearly according to statistics 1/3rd oxygen also has the danger of combustion explosion, is directly threatening operator's personal safety.At the shortcoming that prior art exists, the inventor constantly accumulates experience in practice, has worked out oxygen blast of electric furnace seal of tube ready-packaged joint.This joint has overcome all shortcomings of above existence, has guaranteed the safe operation of producing.
Characteristics of the present utility model are can load and unload oxygen lance, good seal performance safely, easily in the extremely short time, and are air tight, simple in structure, and operation is cheap etc. easily.
The utility model divides two parts to form, and the front portion is the garden pipe overcoat of hollow, and this hollow tube overcoat one end is thin.The other end is thick.The butt end inboard is with screw thread, thin end can make oxygen lance freely stretch into or extract, the rear portion is the heart that has six square nuts, and the front portion of heart is conical surface body, and conical surface front end is with special sealing rubber ring, be complementary with the overcoat conical surface, the position is with screw thread between conical surface body and the hexagonal shaped nut, is complementary with the overcoat inside thread, with screwing six square nuts, compress sealing rubber ring, reach sealing purpose.To be fixedly clamped by the oxygen lance that front end reaches in the rubber ring simultaneously.Afterbody is that oxygen is taken over insertion end.This end is to have the conical surface body that gets stuck, on screw snap ring, the snap ring inboard is with screw thread, is complementary with heart corresponding site screw thread, screws the oxygen that snap ring can compress insertion and takes over, and forms sealing.
Accompanying drawings the utility model.
The utility model is by rotary sleeve (4).Sealing and fixing heart (7) and rotary clip (2) are formed.Oxygen is taken over (1) insertion sealing and fixing heart (7) tail end and is located to rotary clip (2), screws fixedly oxygen adapter (1) of rotary clip (2).Oxygen lance (6) is inserted in the sealing rubber ring (5) from front end, screws six square nuts (3), forces the cover reach of the rubber ring (5) on (7) at heart, with overcoat (4) conical surface tight closure, reaches seal degree, finishes whole docking operations.
