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.
Claims20
A fluid control device manifold comprising:
- 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 formed with a valve hole and a flow passage, the valve hole being located above the flow passage, the flow passage having a center axis along which a fluid passes,
- the main part is formed with a recess on an outer surface of the main part below the flow passage, the recess recessing from the outer surface towards the flow passage,
- the recess is provided with the engagement surface extending in a direction intersecting the center axis of the flow passage,
- the clamp includes a first clamp member and a second clamp member,
- the clamp is configured to clamp the connection part, and
- the engagement surfaces include a surface provided in a screw hole of either or both of the first body and the second body.
