    Abstract: Provided is a fluid control valve assembly including: a main valve body having a first flow passage that is mounted on an inlet of a high-pressure vessel and through which a charging source gas passes, a second flow passage through which a feeding source gas passes, and a third flow passage to which the first flow passage and the second flow passage are connected; a manual valve that is mounted on the main valve body and that opens and closes the third flow passage; a solenoid valve that is mounted on the main valve body and that opens and closes the second flow passage by an electrical signal; a first check valve that is provided on the first flow passage to thus block a reverse flow of the charging source gas; and a second check valve that is provided on the second flow passage to thus block a reverse flow of the feeding source gas, and block the charging source gas from flowing in the second flow passage, to thereby prevent the charging source gas from flowing in the solenoid valve. Accordingly, a charging gas pressure of a high-pressure is prevented from being applied to a solenoid valve, to thereby prevent damage to the solenoid valve and to prevent a malfunction of the solenoid valve.

    Abstract translation: 提供一种流体控制阀组件，包括：主阀体，其具有安装在高压容器的入口上并且充电源气体通过的第一流路，供给源气体通过的第二流路 以及第一流路和第二流路连接的第三流路; 手动阀，其安装在主阀体上并且打开和关闭第三流动通道; 安装在主阀体上并通过电信号打开和​​关闭第二流路的电磁阀; 第一止回阀，其设置在第一流路上，从而阻止充电源气体的逆流; 以及第二止回阀，其设置在所述第二流路上，从而阻止所述供给源气体的反向流动，并且阻止所述充电源气体在所述第二流路中流动，从而防止所述充电源气体在所述第二流路中流动 电磁阀。 因此，能够防止向电磁阀施加高压的充气气体压力，防止电磁阀的损坏，防止电磁阀的故障。

    Abstract: Provided is a valve assembly for a gas vessel including: a valve body mounted at an inlet of the gas vessel and connected to a gas supply source; a connection part connected to the gas supply source on a side surface of the valve body; a check valve mounted on the connection part; and a safety valve mounted on the side surface of the valve body to discharge a fuel gas in the gas vessel to the outside when a gas pressure inside the gas vessel increases above a certain pressure or higher. The valve assembly for a gas vessel is connected to the lower end of the valve body and arranged in the gas vessel to block the gas passage when the fuel gas introduced through the valve body is charged to a set value to prevent overcharging of the fuel gas.

    Abstract: Provided is a fluid control solenoid valve including: a valve body; a valve seat mounted on a lower portion thereof; a coil mounted on an outer circumferential surface thereof and to which power is applied; a core mounted on an inner surface thereof; a lower plunger movably disposed on the inner surface thereof and formed with an orifice and integrally formed with a tight contact portion to be in tight contact with the valve seat on a bottom surface thereof; and an actuating unit arranged to be linearly moved on an upper side of the lower plunger, actuated by interlocking the lower plunger and formed with an actuating rod which is linearly moved and which is in close contact with the orifice. A fluid flow delay unit is provided on an outer surface of the lower plunger to generate pressure difference between upper and lower portions of the lower plunger.
