VALVE DEVICE

摘要

Disclosed is a valve device, comprising: a body (4) having a gas flow passage; and a check valve (16) installed in the gas flow passage and comprising a poppet (84) and a valve seat. The poppet (84) has a hollow shaft shape by having a tapered blockade unit (91) formed in the front end thereof. Moreover, the poppet has at least one horizontal hole (95) connecting the inside and the outside of a hollow shaft-shaped portion. The at least one horizontal hole (95) is formed to be tilted toward the central axial line of the poppet (84) to enable the poppet (84) to be guided in the direction of gas flow inclined against the valve opening direction when the valve is opened. The purpose of the present invention is to provide the valve device restraining occurrence of a joint caused by chattering of the poppet.
