Title:
VALVE DEVICE
Document Type and Number:
Japanese Patent JP2023011200
Kind Code:
A
Abstract:
To provide a valve device capable of suppressing noise while suppressing increase in size of the entire device.SOLUTION: As a joint member 10 is not projected to a valve chest 2A, fluid flow can be prevented from becoming non-uniform in the valve chest 2A when the fluid flows into the valve chest 2A from the joint member 10, flow velocity difference and pressure difference are suppressed, and noise caused by vibration of an electronic valve 1 and passing sound of the fluid can be suppressed. As an area of passing portions A1, A2 is larger than an inner cross-sectional area of the joint member 10, the fluid flowing into the valve chest 2A from the joint member 10 is not throttled, the fluid flow can be stabilized, and the noise can be suppressed. As the joint member 10 is not projected to the valve chest 2A, the passing cross-sectional areas A1, A2 can be easily increased, and increase in size of the entire device can be suppressed.SELECTED DRAWING: Figure 1
