Title:
FLUID-CONTROLLING VALVE HAVING DECOMPRESSION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2021/071173
Kind Code:
A1
Abstract:
A fluid-controlling valve having a decompression function of the present invention comprises: a valve body mounted to a high-pressure container and having a plurality of flow paths formed therein, through which a source gas passes; a manual valve which is mounted to the valve body and manually opens and closes a first flow path connected to the high-pressure container; a solenoid valve which is connected to the manual valve through a second flow path and a third flow path and automatically opens and closes flow paths according to an electric signal; a check valve which is installed at a flow path for filling the high-pressure container with a source gas, to open a flow of one direction while blocking a flow of the opposite direction; a first decompression unit which is connected to the solenoid valve through a fourth flow path to primarily decompress a source gas; and a second decompression unit which is connected to the first decompression unit through a connection flow path to secondarily decompress the primarily decompressed source gas and supply same to a source-using part. Therefore, the fluid-controlling valve can simultaneously function to control filling or releasing of a source gas and decompress the source gas to the working pressure.
