Abstract

A pressure vessel includes a pressure vessel body provided with a flow channel through which a fluid is caused to flow, having a rectangular cross-sectional shape, and formed in an elongated shape, and a circular body flange provided on at least one longitudinal end side of the pressure vessel body, the pressure vessel body has a fluid inlet-outlet port which is provided on the one longitudinal end side and the body flange side of the pressure vessel body and connects with the flow channel and through which the fluid is caused to flow in or out, and the pressure vessel further includes an inlet-outlet header which is formed between the pressure vessel body and the body flange as a closed space connecting with the fluid inlet-outlet port and which the fluid is caused to flow into and out of.

First claim

What is claimed is:

1. A pressure vessel comprising:
a pressure vessel body provided with a flow channel through which a fluid is caused to flow, having a rectangular cross-sectional shape, and formed in an elongated shape; and
a circular body flange provided on at least one longitudinal end side of the pressure vessel body and including an opening portion formed of a through hole, the pressure vessel body being inserted in the body flange,

wherein
the pressure vessel body has a fluid inlet-outlet port which is provided in a side surface on the one longitudinal end side and provided on the body flange side of the pressure vessel body and connects with the flow channel and through which the fluid is caused to flow in or out,
the pressure vessel further comprises an inlet-outlet header which is formed between an outer surface of the pressure vessel body and an inner surface of the body flange as a closed space connecting with the fluid inlet-outlet port and which the fluid is caused to flow into and out of, and
the opening portion of the body flange has a space in which the pressure vessel body is insertable and a space in which the inlet-outlet header is formable.

2. The pressure vessel according to claim 1 , wherein a plurality of the inlet-outlet headers are provided between the outer surface of the pressure vessel body and the inner surface of the body flange.

3. The pressure vessel according to claim 1 , wherein the inlet-outlet header has paired lids on opposite sides thereof in a thickness direction of the body flange, the paired lids forming the closed space.

4. The pressure vessel according to claim 2 , wherein the plurality of the inlet-outlet headers have paired lids on opposite sides thereof in a thickness direction of the body flange, the paired lids forming the closed space.

5. The pressure vessel according to claim 3 , wherein at least one of the paired lids is formed to be openable and closable.

6. The pressure vessel according to claim 4 , wherein at least one of the paired lids is formed to be openable and closable.
