Abstract
The utility model discloses an oxygen lance or sublance sealing plug, which comprises an upper cover plate (3) and a lower cover plate (7). A support rib plate (2), a straight web plate (4), a first inclined web plate (5) and a second inclined web plate (6) are arranged between the upper cover plate (3) and the lower cover plate (7); an oxygen lance or sublance inserting hole is arranged in the center of the sealing plug; a through hole (9) leading to a sealing gas cavity (12) is arranged on the wall of the inserting hole; the sealing plug is formed by splicing at least two portions; and corresponding cover plate steps (11) are arranged at spliced positions of all the portions. The sealing plug with a multi-portion spliced portion is convenient to detach, solves the problem of difficulty in detaching a sealing plug without increasing the consumption of sealing gas, is applicable to straight and conical oxygen lances and sublances, and simultaneously effectively solves the problem of poor sealing effect of a converter oxygen lance hole.
Description
Technical field
The utility model relates to a kind of utility appliance of converter.
Background technology
GB6222-2005 " industrial enterprise's gas safety rules " 5.6.2.1 bar regulation: the coal gas of converter movable gas hood or fixedly petticoat pipe should adopt water cooling, cover mouthful inside and outside differential pressure keeps a stable pressure-fired.Charge cavity on the petticoat pipe, oxygen rifle, sublance patchhole and feed bin etc. should seal and fill nitrogen, keep malleation.The structure formation of existing oxygen rifle/sublance sealing plug generally adopts one-piece construction.This structure exists installation and removal cumbersome, can not be applicable to taper oxygen rifle, sublance at the scene to oxygen rifle or sublance welding block.Simultaneously since the pore of sealing plug for being horizontally disposed with, sealing effectiveness is relatively poor, the situation that flue gas is emerged in the petticoat pipe often occurs.
The utility model content
The purpose of this utility model is to provide a kind of oxygen rifle or sublance sealing plug that adopts detachable structure.
For achieving the above object, the utility model adopts following technical scheme to realize:
A kind of oxygen rifle or sublance sealing plug, comprise upper cover plate and lower cover, have bearing rib, straight web, the first oblique web and the second oblique web between upper cover plate and the lower cover, described sealing plug center is provided with aerobic rifle or sublance patchhole, the wall of patchhole is provided with towards the through hole of blanket gas body cavity, it is characterized in that: described sealing plug is made up of two portions amalgamation at least.
As further optimization, better in order to make sealing property, the mosaic of described each several part is provided with corresponding cover plate step, the direction of described through hole be oblique down, with the angle of horizontal plane be 0 ~ 60
o, described through hole is multi-layer intercrossed layout.
As further optimization, location and installation for convenience, the mosaic of described each several part is provided with corresponding guiding mechanism.
Described cover plate step is provided with fastening piece.
The utility model adopts the structure of many parts amalgamation, the convenient fractionation on the basis that does not increase the blanket gas consumption, solved the problem of sealing plug dismounting difficulty, can be applicable to straight barrel type and taper oxygen rifle and sublance, efficiently solve the problem of converter oxygen gun hole sealing effectiveness difference simultaneously.
Description of drawings
Fig. 1 is that the utility model embodiment assembles preceding synoptic diagram;
Fig. 2 is a left side sealing plug vertical view among Fig. 1;
Fig. 3 is an A-A sectional view among Fig. 2;

Among the figure, part 1 is interior orifice plate, and part 2 is a bearing rib, part 3 is a upper cover plate, part 4 is straight web, and part 5 is the first oblique web, and part 6 is the second oblique web, part 7 is a lower cover, part 8 is fastening piece (containing seal washer), and part 9 is a through hole, and part 10 is a guiding mechanism, part 11 is the cover plate step, and part 12 is the blanket gas body cavity.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and the specific embodiments.
As shown in Figures 1 to 4, a kind of oxygen rifle or sublance sealing plug, comprise upper cover plate 3 and lower cover 7, have bearing rib 2, straight web 4, the first oblique web 5 and the second oblique web 6 between upper cover plate 3 and the lower cover 7, the sealing plug center is provided with aerobic rifle or sublance patchhole, the wall of patchhole is provided with the through hole 9 towards blanket gas body cavity 12, sealing plug is made up of two portions amalgamation, on the sealing upper cover plate 3 of left side sealing plug cover plate step 11 is arranged, it be thought of as a complete round plate after the seal cover board amalgamation with corresponding structure of right side sealing plug is assembled.The nitrogen that the design of this ledge structure can reduce blanket gas body cavity inside leaks by the slit.For the ease of assembling, left side and right side endoporus harden and close the position and have guiding mechanism 10, and guiding mechanism 10 also has the effect of sealing.For fixing left and right sealing plug, at upper and lower cover plate place the circular hole that fastening piece 8 is installed is arranged, two portions sealing plug is undertaken fastening by the fastening piece 8 of upper cover plate interlock place and the fastening piece 8 of lower cover interlock place.The direction of through hole 9 be oblique down, with the angle of horizontal plane be 45
o, and through hole 9 is multi-layer intercrossed layout.Such design has further improved sealing property again.
The utility model is convenient to be split, and can not impact other equipment during dismounting, can be applicable to the sealing of taper oxygen rifle, sublance, and sealing effectiveness is better, long service life.This kind structure also can be applied in the equipment of the other field similar with oxygen muzzle seal request simultaneously.
The above only is preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction.To any simple modification that above embodiment did, equivalent variations, modification, improvement etc. all still belong in the scope of technical solutions of the utility model according to technical spirit of the present utility model.
