Abstract
Provided is a flow rate adjustment device including: a diaphragm integrated valve body; a valve seat section provided around an inflow opening and including a valve seat surface disposed at a position facing a valve surface; and a transfer mechanism configured to cause the diaphragm integrated valve body to move along an axis line to adjust a distance between the valve surface and the valve seat surface. The valve surface 11a and the valve seat surface form an angle, which is an acute angle, with the axis line and are disposed in parallel.
Claims6
A flow rate adjustment device that adjusts a flow rate of a fluid circulating through an internal flow path, the flow rate adjustment device comprising:
- a valve body section configured to move along an axis line within a valve chest and including a base, the base having a bottom surface facing a bottom surface of the valve chest and a valve surface formed around the axis line;
- a valve seat section including a valve seat surface disposed at a position facing the valve surface;
- and
- a transfer mechanism coupled to the valve body section and configured to cause the valve body section to move along the axis line to adjust a distance between the valve surface and the valve seat surface,
- wherein a flow path opening is provided on the valve seat surface, the flow path opening allowing the valve chest and the internal flow path to communicate with each other,
- wherein the valve surface and the valve seat surface form an acute angle with the axis line and are disposed in parallel,
- wherein the valve surface and the valve seat surface are surfaces formed in a planar shape, and
- wherein the internal flow path extends from the flow path opening provided on the valve seat surface in a direction that inclines relative to the axis line.
