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.
