Rotary compensator for heating pipe, resistant to -40℃-350℃, well sealed, large compensation
Purpose
The rotating compensator is generally installed in a group of
150~500m on the pipeline (it can be determined according to the
natural terrain). There are more than ten installation forms, and
the arrangement form can be determined according to the direction
of the pipeline. After adopting this type of compensator, the
distance between the fixed brackets is increased. In order to avoid
the deflection of the pipe section, the guide bracket should be
appropriately added. It is a displacement compensation device for
heating network pipelines. The rotary compensator is mainly
composed of inner and outer pipes, sealing fillers and spring
compression devices. The utility model is characterized in that a
high-precision processing method is used to achieve a small fit gap
between the spring compression flange and the inner tube. Two to
three pieces of the utility model are combined to absorb and
compensate the axial displacement and axial thrust of the heating
network pipeline. The product has good sealing performance, no need
to stop production and maintenance, and the product adopts
precision processing, which makes the coordination of product parts
more reasonable, ensures the product concentricity, greatly
improves the product's ability to withstand angular and lateral
displacement, has good stability, and improves product safety Sex
and tightness.
Advantages:
Rotating compensator is a new type of compensator for thermal
expansion compensation of thermal pipelines. The structure of the
rotating compensator is mainly composed of integral sealing seat,
sealing gland, size head, anti-friction centering bearing, sealing
material, rotating cylinder and other components. It needs more
than two pairs to form a group to form a relative The rotation
absorbs the thermal displacement of the pipeline, thereby reducing
the stress of the pipeline.
Advantages of rotating compensator:
(1) The amount of compensation is large, which can be arranged
according to the natural terrain and the strength of the pipeline.
The largest set of compensators can compensate for a 500m pipe
section;
(2) There is no blind plate force generated by medium pressure, and
the fixing bracket can be made small, especially suitable for
large-diameter pipelines;
(3) Superior sealing performance, no maintenance required for
long-term operation;
(4) The investment is greatly saved;
(5) Convenient design and calculation;
(6) The rotary compensator can be installed on the steam
underground pipe and the hot water underground pipe, which can save
a lot of investment and improve operation safety.
