Abstract

A fluid loading joint includes: a first half provided at an end of a first vacuum double pipe, the first half including a first inner pipe, a first outer pipe, and a first blocking member blocking between the first inner pipe and the first outer pipe; a second half provided at an end of a second vacuum double pipe, the second half including a second inner pipe, a second outer pipe, and a second blocking member blocking between the second inner pipe and the second outer pipe; an annular inner insulator interposed between the first inner pipe and the second inner pipe; and an annular outer insulator interposed between the first outer pipe and the second outer pipe, the outer insulator surrounding the inner insulator, with a gas space positioned between the outer insulator and the inner insulator, the gas space being formed between the first blocking member and the second blocking member.

First claim

The invention claimed is:

1. A fluid loading joint that is a swivel joint, the fluid loading joint comprising:
a first half provided at an end of a first vacuum double pipe, the first half including a first inner pipe, a first outer pipe, a first blocking member, and a cylindrical holder, the first inner pipe being provided with a first inner flange at a distal end of the first inner pipe, the first outer pipe forming a vacuum space between the first inner pipe and the first outer pipe, the first blocking member blocking between the first inner pipe and the first outer pipe, the cylindrical holder holding the first outer pipe such that the first outer pipe is rotatable;
a second half provided at an end of a second vacuum double pipe, the second half including a second inner pipe, a second outer pipe, and a second blocking member, the second inner pipe being provided with a second inner flange at a distal end of the second inner pipe, the second outer pipe forming a vacuum space between the second inner pipe and the second outer pipe and being provided with an outer flange at a distal end of the second outer pipe, the outer flange being fastened to the holder, the second blocking member blocking between the second inner pipe and the second outer pipe and forming a gas space between the first blocking member and the second blocking member, the gas space being filled with gas;
an annular inner insulator interposed between the first inner flange and the second inner flange; and
an annular outer insulator interposed between the holder and the outer flange, the outer insulator surrounding the inner insulator, with the gas space positioned between the outer insulator and the inner insulator.

2. The fluid loading joint according claim 1 , further comprising a spacer interposed between the first inner flange and the second inner flange, the spacer being fastened to the second inner flange and slidable on the first inner flange, wherein
the inner insulator is sandwiched between the spacer and the second inner flange.

3. Fluid loading equipment comprising the fluid loading joint according to claim 2 .

4. Fluid loading equipment comprising the fluid loading joint according to claim 1 .
