EXPANSION JOINT AND COMPRESSION SYSTEM

摘要

An expansion joint, which connects pipes to each other and is capable of expanding and contracting, the joint being provided with: a first end pipe and a second end pipe; a connecting pipe for connecting the first end pipe to the second end pipe so as to be capable of approaching and separating from each other; and a thrust-absorbing means having a pressure chamber, which can expand and contract in the direction in which the first end pipe and the second end pipe are linked and into which a fluid pressure that differs from the pressure inside the pipes can be introduced, the pressure chamber comprising a first pressure-receiving section, which is fixed to the first end pipe and faces in the direction from the second end pipe toward the first end pipe, and a second pressure-receiving section, which is fixed to the second end pipe and faces in the direction from the first end pipe towards the second end pipe.

1. An expansion joint which connects pipes to each other and is capable of expanding and contracting, comprising:
an end pipe on one side and an end pipe on the other side; a connecting pipe which connects the end pipe on one side and the end pipe on the other side so as to be capable of coming close to each other and separating from each other; and thrust-absorbing means having a pressure chamber which can expand and contract in a direction connecting the end pipe on one side and the end pipe on the other side and into which a fluid pressure different from a pressure in the pipes can be introduced, the pressure chamber having a pressure-receiving section on one side, which is fixed to the end pipe on one side and faces in a direction from the end pipe the other side to the end pipe on one side, and a pressure-receiving section on the other side, which is fixed to the end pipe on the other side and faces in a direction from the end pipe on one side to the end pipe on the other side.
