Introduction: Now the key to describe the application of bidirectional sleeve compensator, unidirectional sleeve compensator and universal ball compensator in heating pipe network, and how to determine the classification, model, performance characteristics, selection and calculation, installation and other common problems of compensator products. One: set

Now the key is to describe the two directions Sleeve Compensator , unidirectional sleeve compensator, universal spherical compensator for thermal expansion How to determine the classification, model, performance characteristics, type selection, calculation, installation and other common problems of compensator products.
1. Sleeve compensator is a new type of thermal compensation equipment for fluid pipeline, and various forms of pipe network laying (empty frame, pipe trench and direct burial) can be considered.
(1) bidirectional sleeve compensator
Performance characteristics: bidirectional, bidirectional compensation, bidirectional drainage, can be applied to circulating pipe network. Directly buried without maintenance, reducing costs, buried with the pipeline, no observation wells, no regular maintenance can reduce the operation cost and maintenance cost. The two-way sleeve compensator is used for the geographical environment with high groundwater level. Wide channel self tightening seal is selected for 15-20 years, no leakage, no instability, anti pulling off, high coaxiality, which can avoid the damage caused by excessive side force. To reduce the project budget, the matching form of the shell and the core tube is the dynamic fit in the mechanical coordination form, so that the guide bracket spacing can be designed by the visitors. It is convenient for construction. During installation, the bidirectional sleeve compensator is located in the middle of the two support frames without pre stretching. It can be welded with the pipeline and is suitable for all laying methods. The construction site is not affected by the unique location of the pipeline, such as the pipeline network, which can not be adjusted by the natural conditions.
(2) unidirectional sleeve compensator
Performance features: unidirectional drainage, direct burial, maintenance free, cost reduction, no observation well and regular maintenance when buried with pipelines can reduce operation cost and maintenance cost. Wide channel self tightening seal is selected for 15-20 years, no leakage, no instability, anti pulling off, high coaxiality, which can avoid the damage caused by excessive side force. Fully sealed, the outer protective cover and the outer flange are fully sealed and welded, and the movable end of the rear end pipe is selected with reduced seal, so that the key components at the sealing position of the compensator are separated from the external, effectively avoiding external erosion. It is suitable for areas with high underground water level and integrated into various working conditions and natural environment. The key components are provided with anti-corrosion solution and have the same service life as the pipe network. In order to reduce the cost of man-made core tube in the design, the man-machine spacing can be reduced. It is convenient for construction. During installation, the fixed end of the one-way sleeve compensator should be close to the support frame without pre stretching. It can be welded with the pipeline. It is suitable for all laying methods. The compensator is not limited by the construction conditions, which provides great convenience for the pipe network construction.
2、 Universal ball compensator
The universal ball type compensator absorbs the displacement of the pipeline by the rotation of the ball head relative to the outer shell parts, which is very suitable for the pipeline laying in any plane or space forming a bend. Generally, it is used in a group of 2-3. The compensator is installed at the bend of the pipeline, and the rotation of the ball head is used to achieve the purpose of compensation.
Structural features: metal base material spherical bearing bearing force and rest assured, replacing the general ball type compensator with sealing stress and rest assured, using flange cover to carry out adjustment, so as to ensure more reliable sealing. The overall welding structure is selected, and all running parts are fully contained. The bearing has a high self lubrication index. A part of spherical surface with high smoothness is densified with closed cleaning plate, which is very suitable for coal ash transportation pipeline. The spherical surface has unique solution, and has more corrosion resistance.
