Balanced sleeve compensatorIt includes an inner tube (1), a cover (2), a packing (3), a left shell (4), a blind tube (5), and a right shell (6); The left shell (4) and blind tube (5) are respectively coaxially fitted with the inner tube (1), and the filling material (3) embedded in the overlapping section is compacted by a pressing cover (2) to form a pair of sliding sealing pairs. The left outer walls of the left shell (4) and blind tube (5) are uniformly distributed with filling tubes (6.1) that communicate with the filling material (3); Its feature is that the right end of the blind pipe (5) is a conical top facing right, and the outer wall is equipped with an exhaust pipe (6.2) that communicates with atmospheric pressure; The right shell (6) is coaxially spaced with the blind pipe (5), and the two are radially connected through a filling pipe (6.1) and an exhaust pipe (6.2). The right shell (6) and the left shell (4) are connected as a whole by a flange edge; The middle section of the inner tube (1) is equipped with a conical partition (1.1) with a conical top facing left. 5-12 through holes (1.2) are evenly distributed on the inner tube wall, which are located on the left side of the partition (1.1) and bypass to the inner cavity of the left shell (4). The total area of the through holes (1.2) is equal to or greater than the transverse cross-sectional area of the inner hole of the inner tube (1).
Balanced sleevecompensatorStructural characteristics
Three packing sealed chambers are used to design a closed fluid ring chamber. During operation, the fluid static pressure inside the pipeline is utilized to generate tension on the two sides of the pipeline connected to it. Its tensile value is basically equal to the product of the fluid static pressure and the cross-sectional area of the pipeline flow. In this way, the thrust generated by the fluid static pressure acting on the fixed support at the bend or blind end of the pipeline is offset. Thus, the thrust acting on the fixed bracket at that location is significantly reduced, eliminating the shortcomings of ordinary filling sleeve compensators in this regard. Therefore, simplifying the design and construction of the fixed bracket is more important, especially in situations where high voltage, elevated space, and structural space are limited, but the structure is more complex and the cost is higher.
