Abstract:
The present invention relates to the technical field of offshore jacket mounting. Disclosed is a Y-shaped packer. The Y-shaped packer is arranged in an annular gap between an outer cylinder (1) and an inner cylinder (2), and the Y-shaped packer comprises: a support portion (3), which is of an annular structure and is fixedly sleeved on an outer wall of the inner cylinder; a blocking portion (4), which is also of an annular structure, wherein the inner end of the blocking portion is connected to an outer wall of the support portion, and the outer end of the blocking portion is inclined upwards, such that an included angle between the blocking portion and the support portion is an acute angle; and an expansion seal (10), which is of an annular structure, wherein the expansion seal is connected to the support portion, and the expansion seal is located above the blocking portion. The Y-shaped packer can achieve the effect of secondary sealing of the gap between the outer cylinder and the inner cylinder by means of combining the support portion, which is obliquely arranged, and the expansion seal, which is arranged above the support portion.
