。[Scope of Claim for Utility Model Registration] (1) A large-diameter cylindrical portion 4 that fits into the upper end of a casing 2 made of a steel pipe and the lower end of a casing 3 made of a steel pipe connected to the upper end of the casing 2, respectively. and a small diameter cylindrical part 5 are provided, and the inner and outer peripheral surfaces of the large diameter cylindrical part 4 and the small diameter cylindrical part 5 are provided with a concave part 6 and a convex part that fit into each other when the small diameter cylindrical part 5 is inserted into the large diameter cylindrical part 4. A pair of grooves 8 and 9 are formed in a direction substantially orthogonal to the axial direction of the casings 2 and 3 in opposing parts of the inner and outer peripheral surfaces of the recess 6 and the protrusion 7,
A casing joint that connects the large-diameter cylindrical portion 4 and the small-diameter cylindrical portion 5 by inserting the colander 10 in a state spanning both of these grooves 8 and 9. (2) A ring-shaped packing receiver 11 is provided protrudingly on the inner peripheral surface of the large-diameter cylindrical portion 4 with a predetermined distance between it and the end surface of the small-diameter cylindrical portion 5. A lip portion 12a is formed between the seat 11 and the small diameter cylindrical portion 5 due to an increase in pressure within the casing.
expands, and the packing catch 11 to the large diameter cylindrical portion 4
2. The casing joint according to claim 1, wherein a ring-shaped packing 12 is attached to seal the space between the small-diameter cylindrical portion 5 and the small-diameter cylindrical portion 5.
