Description
Technical field
The invention belongs to metallurgical gas pipeline compensation technique field, particularly relate to a kind of compensator deflection and visually disguise
Put.
Background technology
Compensator is the most also expansion joint, or telescopic joint.By the corrugated tube constituting its operative body and end pipe, support,
The adnexa such as flange, conduit forms, and belongs to a kind of compensating element,.Utilize effective dilatation of its operative body corrugated tube, to inhale
Closed tube line, conduit, container etc. are by the change in size reason such as expanding with heat and contract with cold and produce, or the axle of compensation pipes, conduit, container etc.
To, laterally and angular displacement.Conventional has square (П shape or Ω shape), material filling type, waveform, spherical, telescoping tube type, cydariform, L-shaped
With Z-shaped compensator etc., of many uses in modern industry.
Metallurgical gas pipeline uses the compensators such as waveform, material filling type, bend pipe, cydariform for extraction duct because of outside gas in a large number
The factors such as temperature, delivered inside medium temperature change cause pipeline axial stretching variable.
Bellow expansion joint be generally used for pressure less than 0.7MPa, temperature be 30～450 DEG C, nominal diameter is more than 100mm
Pipeline on, it is connected with pipeline Flange joint and welding.Bellow expansion joint can be used for horizontal pipeline section, vertical pipeline section and bending
On pipeline section, the compensator of band clamp device when bending tube section is installed, can be used, when horizontal pipeline section is installed, band can be used
The compensator of steam trap, and drain pipe is guided to the draining place specified.Compensator (is i.e. designed by the zero temperature of design code
Peak temperature and the midpoint of minimum point temperature) location.Can not carry out when installation environment temperature is equal or close to zero temperature
Prestretching (or precompressed)；Precommpression is answered when installation environment temperature is higher than zero temperature；Otherwise answer prestretched.Should behind compensator location
Fix immediately.Small-sized compensator can be with artificial or chain hoist lifting, and big-and-middle-sized compensator lifting machine lifts.During lifting
It should be noted that protection node and joint.During installation it should be noted that the direction of compensator so that it is keep concentric with pipeline；And can use interim
Fixation means, removes after Pipe installing.
Material filling type compensator is also known as pipe-type compensator, and point cast iron and steel two kinds, the mode being connected with pipeline has flange
Connect and weld.Before installation, the centering necessary with shell of the inner sleeve of compensator, must not there is deflection.During pipeline straightening centering, compensate
Device should not allow radial force with pipeline centering.Near compensator both sides, guiding trestle should be installed, it is ensured that compensator freely stretches
Time without departing from axial line.The friction portion of compensator should be coated with machine oil, and non-model control part should be coated with antirust paint.Filler asbestos cord should be coated with
Graphite powder, from coil to coil loading from coil to coil compress, and respectively enclose joint and mutually to stagger, between its thickness is not less than between sleeve and shell
Gap.
Foregoing illustrating the compensator structure that metallurgical gas pipeline uses, it is all kinds of that existing compensator all exists shortcoming
Compensator all cannot directly display compensator deflection, and once compensator compensates excess, be susceptible to compensator fatigue damage,
The accident such as come off, and affects the safe and stable operation of system.
