Heating network compensator, also called maintenance-free thrustless rotation compensator, is a displacement compensation device for heating network pipes. It is mainly composed of inner and outer tubes, sealing packing and spring pressure. Composed of tightening device. It is characterized in that high-precision machining is used to achieve a small fitting gap between the spring compression flange and the inner tube. Two or three of the utility model are used in combination to absorb and compensate the axial displacement and axial thrust of the heat network pipe. The product has good sealing performance and does not need to be shut down for maintenance. Moreover, the product adopts precision processing, which makes the cooperation between product parts more reasonable and the assembly more precise, ensuring the concentricity of the product. The product's ability to withstand angular and lateral displacement is greatly improved, and the stability is good, improving Ensure product safety and sealing.
The rotary compensator is a new type of compensator for thermal expansion compensation of thermal pipelines. The structure of the rotary compensator mainly consists of an integral sealing seat, a sealing gland, a large and small head, an anti-friction centering bearing, a sealing material, a rotating cylinder and other components. When installed on a thermal pipeline, two or more groups are required to form a relative The rotation absorbs the thermal displacement of the pipeline, thereby reducing the stress on the pipeline.
Advantages of rotating compensators
Large compensation amount, can be arranged according to natural terrain and pipeline strength, the largest group of compensators can compensate for pipe sections
No blind plate force generated by medium pressure , the fixed bracket can be made very small, especially suitable for large-diameter pipes
, excellent sealing performance, no maintenance required for long-term operation
, great investment savings
, easy design and calculation
, The rotary compensator can be installed on steam underground pipes and hot water underground pipes, which can save a lot of investment and improve operational safety.
Rotary compensators are generally installed in groups on the pipeline (there are more than ten installation forms that can be determined according to the natural terrain, and the layout can be determined according to the direction of the pipeline. After using this type of compensator, the distance between the fixed brackets increases , in order to avoid deflection of the pipe section, the guide bracket should be appropriately added. In order to reduce the friction resistance of the pipe section operation, a rolling bearing should be installed on the sliding bracket.
