Y-SHAPED PACKER
A Y-shaped packer includes a supporting part, fixedly sleeved on the outer wall of the inner barrel; a plugging part having an inner end part connected with the outer wall of the supporting part, and an outer end part tilted upward so that an angle between the plugging part and the supporting part is an acute angle; an expansion seal connected with the supporting part. The expansion seal is located above the plugging part. The Y-shaped packer is arranged in an annular gap between an outer barrel and an inner barrel. Through the combination of the supporting part arranged obliquely and the expansion seal arranged above the supporting part, the invention-shaped packer can realize the effect of secondary sealing on the gap between the outer barrel and the inner barrel.
