Abstract
The utility model provides a horizontal displacement compensation type sealing device which is used between a water-cooling plate suspension rod at the furnace roof of a steelmaking converter and a pipeline open hole. The horizontal displacement compensation type sealing device comprises a fixed sleeve and a movable sleeve, the fixed sleeve and the movable sleeve are coaxially arranged at the upper and the lower parts along a rod part, a sliding groove is formed on the fixed sleeve and a bottom plate of the movable sleeve is inserted in the sliding groove of the fixed sleeve, and the movable sleeve is provided with a labyrinth seal for sealing and preventing gas from overflowing along the rod part. As the horizontal displacement compensation type sealing device adopts the structure of the matched fixed sleeve and the movable sleeve, the lower end of the movable sleeve is inserted in the sliding groove of the fixed sleeve and the movable sleeve can slide along any horizontal direction within the design range, enough horizontal gap is remained between the two to compensate the horizontal displacement of the rod part; and meanwhile, the movable sleeve is provided with the labyrinth seal for preventing the gas from overflowing along the rod part. The whole device has simple structure, convenient installation and maintenance and long service life. The device can also be used in the occasions of rough sealing of other high-temperature atmospheric-pressure reciprocating motion rod parts.
Description
Technical field
The utility model belongs to the auxiliary facility of steel-making converter, is specifically related to the horizontal shift compensating type sealing device between steel-making converter furnace roof cooled plate suspension rod and the pipeline tapping.
Background technology
At present all to change the upper end into fixing for the waste heat boiler of steel-making converter, produces very big vertical translation (60～100mm) and horizontal shift when the boiler lower end is heated.Cause the waste heat boiler movable gas hood correspondingly to produce horizontal shift.
Because the petticoat pipe hoisting appliance is installed on the upper platform, suspension rod passes the furnace roof cooled plate.The cooled plate perforate will be satisfied the lifting to-and-fro movement and the horizontal shift of suspension rod on the one hand, will reduce the slit on the other hand as far as possible and spill into the cooled plate top to reduce flue gas.
Common processing mode is out enough big hole, and with the slit between stifled suspension rod of rock wool and the hole, because the motion extruding of suspension rod and washing away of high temperature gas flow, the work-ing life of rock wool is very short, can not guarantee sealing effectiveness then.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to maintenance, the compound seal of long service life and the horizontal shift compensating type sealing device of two kinds of functions of bit shift compensation.
The purpose of this utility model is achieved in that it comprises permanent sleeve, movable sleeve, is characterized in, permanent sleeve and movable sleeve are along rod member coaxial arrangement up and down, and permanent sleeve has chute, and the base plate of movable sleeve inserts in the chute of permanent sleeve.
Concrete structure of the present utility model has, and movable sleeve has labyrinth seal, and gas overflows along rod member only to blockade.
The utility model is because the structure formation that has adopted permanent sleeve, movable sleeve to match, the movable sleeve lower end can be inserted in the chute of permanent sleeve, be actively set in the scope of design and can slide along any direction of level, leave of the horizontal shift of enough horizontal clearances between movable sleeve external diameter and the permanent sleeve internal diameter with the compensation rod member, simultaneously movable sleeve has labyrinth seal and stops gas to overflow along rod member, and whole apparatus structure is simple, installation, easy to maintenance, long service life.This device also can be used for the occasion of the thick sealing of other high-temperature pressure to-and-fro movement rod member.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
The embodiment that the utility model is done below in conjunction with accompanying drawing elaborates:
As shown in the figure, the utility model mainly comprises permanent sleeve 1, movable sleeve 2, be characterized in, permanent sleeve 1 and movable sleeve 2 are along rod member coaxial arrangement about in the of 6, permanent sleeve has chute 3, the base plate 4 of movable sleeve inserts in the chute 3 of permanent sleeve, is guaranteed to be free to slide relatively by running fit or dry lubrication, and slides to satisfy rod member 6 horizontal shift requirements at horizontal any direction.
As shown in the figure, movable sleeve 2 has labyrinth seal 5, and cross-sectional shape is determined by rod member 6 or pipeline; Gas overflows along rod member 6 only to blockade.In less demanding occasion, labyrinth seal structure also can be cancelled, and adds a base plate thereby movable sleeve can be reduced to a sleeve, or base plate is only arranged.
As shown in the figure, movable sleeve 2 is installed in permanent sleeve 1 top, and according to field condition, movable sleeve 2 also can be installed in the below of permanent sleeve 1, can play same effect equally.
For easy for installation, movable sleeve or permanent sleeve can be made along the axis separated into two parts, and design suitable web member and connect, but also site welding becomes whole movable sleeve and permanent sleeve.
Claims (3)
1. horizontal shift compensating type sealing device, comprise permanent sleeve (1), movable sleeve (2), it is characterized in that, permanent sleeve (1) and movable sleeve (2) are along rod member (6) coaxial arrangement up and down, permanent sleeve (1) has chute (3), and the base plate (4) of movable sleeve (2) inserts in the chute (3) of permanent sleeve (1).
2. horizontal shift compensating type sealing device according to claim 1 is characterized in that, movable sleeve has labyrinth seal (5).
3. horizontal shift compensating type sealing device according to claim 1 is characterized in that, movable sleeve (2) is installed in above or below the permanent sleeve (1).
