Embodiment Construction
[0011] The rotary flange of this embodiment is as figure 1 As shown, it includes a first connecting pipe 1 and a second connecting pipe 8 with equal diameters opposite to each other. The outer circle of the first connecting pipe is welded and fixedly connected with a fixed flange 2 whose end face exceeds the first connecting port, and the outer circle of the second connecting pipe is welded and fixedly connected with a retaining ring 5 whose end face exceeds the second connecting port. The end face of the fixed flange 2 adjacent to the retaining ring 5 is formed with a depression whose diameter matches the outer circle of the retaining ring, and the end face of the retaining ring 5 facing away from the fixed flange 2 has a ring groove. After assembly, the fixed flange 2 is connected with the loose flange 7 sleeved on the outer circle of the second connecting pipe 8 through fastening bolts 10 . The end face of the loose flange 7 adjacent to the fixed flange 2 is in contact wit...

The utility model relates to a rotary flange, belonging to the technical field of pipeline connection. The first connection pipe of the rotary flange is fixedly connected with a fixed flange, and the second connection pipe thereof is fixedly connected with a check ring; the end face of the fixed flange close to the check ring is provided with a dent having a diameter matched with the outer circleof the check ring, and the end face of the check ring depart from the fixed flange is provided with a circular groove; the fixed flange is connected with a loose flange sheathed on the outer circle of the second connection pipe through a fastener; the end surface of the loose flange is contacted with rolling balls arranged in the circular groove on the end face of the check ring; the check ring is embedded into the dent of the fixed flange and pressed on the sealing gasket embedded in the dent; a sealing ring is arranged between the opposite terminals of the first connection pipe and the second connection pipe; and the thickness of the sealing ring is matched with the distance between the opposite terminals of the first connection pipe and the second connection pipe. In the invention, thestress deformation of pipeline can be compensated, and the pressure fluid in the pipeline also enables the sealing ring to produce the trend of being tightly clung with the fixed flange, the inner circle of the check ring, and the terminals of the two connection pipes, thus the rotary flange has reliable sealing effect.
Description
technical field [0001] The invention relates to a flange, in particular to a rotating flange capable of compensating for pipeline deformation, and belongs to the technical field of pipeline connection. Background technique [0002] The use of rotating flanges in thermal piping can compensate the relative deformation of the butt pipes to a certain extent, and is cost-effective. However, as far as the applicant knows, the ubiquitous sealing problem of the existing rotary flange is difficult to solve. [0003] The search found that the Chinese patent application with application number 200720200509.6 discloses a rotating flange, which includes an upper flange, a lower flange, a pressure bearing body and a locking ring; the pressure bearing body and the lower flange are fixedly installed together, and the The outer upper part of the pressure body is fitted with an upper flange, and a sealing ring is installed between the pressure body and the upper flange. There is a boss on th...
