Description
Technical field
The invention belongs to the technical field of swivel joint, more particularly to a kind of swivel joint for water cooled rolls.
Background technology
In industries such as steel, papermaking, using more water cooled rolls, the workpiece temperature of working environment or contact residing for roll body
Degree is higher, in order to cool down to roll body, while reduces the temperature of roll body bearing, bearing service life is improved, inside roll body
Chilled(cooling) water return (CWR) is set, is connected in roll body end with cooling water.Because roll body does circle rotation movement, and cooling water pipeline is fixed
It is motionless, it is necessary to install swivel joint to connect fixed cooling water pipeline and rotating roll body home loop.
In the factory of steel industry, typical water cooled rolls is the water cooling furnace roller of annealing furnace, water cooling contact roller, water cooling tower top
The roll bodies such as roller, from 300 degrees Celsius to 900 degrees Celsius, even more high, inputs the operating ambient temperature of these roll bodies from roll body end
Cooling water the circulation of a cycle is carried out inside roll body, take away partial heat, cold in-water temperature is generally below 35 and takes the photograph
Family name's degree, leaving water temperature is up to 60-75 degrees Celsius, and roll body bearings at both ends and bearing block temperature control are below 85 degrees Celsius.
When cooling water system breaks down, the water temperature inside roll body in circulation loop will persistently rise, and even up to boil
The temperature of point, bearing and bearing block is also rapid therewith to be risen, and lubricant grease temperature also rises therewith, once bearing is in for a long time
Run under the condition of high temperature, the service life will drastically decline, or even can be damaged, and cause a series of failures.
The swivel joint service life domestic at present is shorter, and main cause is each component manufacturing accuracy of swivel joint, assembly precision
Generally, sealing ring material is substantially identical with imported product, but since overall precision is general, the ring portion and stationary ring of sealing ring
Part discontinuity equalization, abrasion is very fast, and local infiltration, leaks overstocked water as connector rotates, may penetrate into rotation and connect
Bearing inside head, lubricant grease failure, bearing produce corrosion after causing bearing lubrication grease emulsion deterioration, time permanent,
Gap increases, and reduces the kinematic accuracy of rotary part, exacerbates the abrasion of sealing ring, occurs swivel joint leak rapidly and show
As.
The content of the invention
The technical problems to be solved by the invention are to be directed to above-mentioned problem, there is provided a kind of rotation for water cooled rolls
Adapter, ensures the running precision of swivel joint, extends the service life of swivel joint.
Technical solution is used by the present invention solves above-mentioned technical problem：A kind of swivel joint for water cooled rolls, its
Be characterized in that, including anchor tip, fixed shell, rotation housing, bearing, bearing block, spring, sliding seat, fixing seal ring and
Rotating seal ring, the anchor tip are connected with one end of the fixed shell, the other end of fixed shell and the bearing block
It is connected, the bearing is arranged between bearing block and the rotation housing, and is positioned and be connected by baffle ring, and the sliding seat passes through tune
Section bolt is fixed on the inner wall of fixed shell, and the both ends of the spring offsets with fixed shell and sliding seat respectively, the fixation
Sealing ring is embedded on the end face of sliding seat, the rotating seal ring be embedded at rotation housing end face on, fixing seal ring with
The corresponding setting of rotating seal ring, the bottom of fixed shell are equipped with water outlet.
By such scheme, the bearing medial extremity is equipped with lip-type packing.
By such scheme, the bearing block is equipped with grease fitting.
By such scheme, the fixing seal ring and rotating seal ring are made by carborundum.
By such scheme, O-ring seal is equipped between the sliding seat and the fixed shell inner wall.
The beneficial effects of the invention are as follows：The 1st, a kind of swivel joint for water cooled rolls is provided, pass through the pressure of presetting spring
Power, may be such that fixing seal ring is in close contact with rotating seal ring, and after sealing ring produces certain abrasion, spring elongation,
Wear extent is made up, is prolonged the service life；2nd, lip-type packing is added in bearing block medial extremity, it is further close to bearing block inner cavity
Envelope, reduces cooling water and immerses bearing, ensure bearing running precision, ensure the running precision of swivel joint, extend swivel joint
Service life.
