Abstract
A fluid control device manifold includes a first body, a second body, and a connection part configured to interpose a seal member between the first and second bodies and allow a connecting tool to engage with engagement surfaces of the bodies. When a load is applied to the engagement surfaces to draw the first and second bodies close to each other, the seal member is press-fitted into the bodies. This press-fitted state is held by a clamp. One or both of the first and second bodies are internally provided with a plurality of the engagement surfaces extending in a nearly perpendicular direction to a drawing direction.

A fluid control device manifold including a first body, a second body, and a connection part configured to interpose a seal member between the first and second bodies, the seal member being in a press-fitted state in the first and second bodies in a manner that a connecting tool is engaged with engagement surfaces of the first body and the second body and a load is applied to the engagement surfaces to draw the first body and the second body toward each other, and the press-fitted state is held by a clamp,
- wherein a main part of either or both of the first body and the second body is provided, on an inner side, with the engagement surface extending in a nearly perpendicular direction to a drawing direction.
A method for assembling a manifold including a first body, a second body, and a connection part, the method including:
- interposing a seal member between the first and second bodies;
- engaging a connecting tool with the first and second bodies;
- applying a load to engagement surfaces of the first and second bodies to draw the first and second bodies toward each other so that the seal member is placed in a press-fitted state;
- and holding the press-fitted state by a clamp,
- wherein the method utilizes a plurality of the engagement surfaces located on an inner side of a main part of either or both of the first body and the second body, the engagement surfaces each extending in a nearly perpendicular direction to a drawing direction.
A connecting tool for applying a load to engagement surfaces of a first body and a second body between which a seal member is interposed, drawing the first body and the second body toward each other so that the seal member is placed in a press-fitted state in the first body and the second body,
- wherein the connecting tool includes engagement surfaces engageable with a plurality of the engagement surfaces located on an inner side of a main body of either or both of the first body and the second body, the engagement surfaces each extending in a nearly perpendicular direction to a drawing direction.
