9, when power is supplied to the coil 76, the plunger 74 is first retracted, and the plunger 74 is connected to the plunger 74. In this case, The orifice 90 formed in the valve body member 72 is opened while the contact member 92 is retracted. Then, the material gas filled in the gas inlet / outlet port 80 passes through the orifice 90, so that the gas flow path is in a communicated state, thereby relieving the shock when the valve is opened and closed.

12, when the plunger 74 is retracted secondarily, the valve member 72 is lowered and separated from the seat portion 86 so that the gas passage 82 and the gas inlet / outlet 80 are communicated with each other . Then, the raw material gas flowing into the gas passage 82 is discharged through the gas inlet / outlet 80.

As described above, the present solenoid valve minimizes the influence of the filling pressure of the raw material gas by communicating with the primary gas through the orifice 90 when filling the raw material gas, thereby preventing malfunction or durability deterioration, can do.

The pressure release device 18 is mounted on the fifth mounting portion 58 of the valve body 10 and communicates with the high pressure vessel 100 and the third flow passage 28 so that the temperature of the high pressure vessel 100 rises The pressure in the high-pressure vessel 100 is released to the outside. For example, when a fluid control system according to the present embodiment is installed in a hydrogen-fueled vehicle, when a fire occurs in a vehicle due to an accident or fire of a vehicle, the pressure in the high-pressure vessel 100 is released to the outside, 100).

The operation of the valve assembly according to one embodiment of the present invention thus constructed will be described below.

FIG. 13 is a configuration diagram for gas filling of a fluid control valve assembly according to an embodiment of the present invention, and FIG. 14 is a configuration diagram for gas control of a fluid control valve assembly according to an embodiment of the present invention.

13, when the raw material gas is filled, the raw gas is passed through the second flow path 22 and the first flow path 20 as shown by the arrow C, and the raw gas is charged into the high pressure vessel 100, 14, when the raw material gas passes through the first flow path 20 and the second flow path 22, the raw material gas stored in the high-pressure vessel 100 is discharged, as shown by arrow D in FIG.

As described above, since the valve assembly of the present invention is moved through the first flow path 20 and the second flow path 22, which are the same when filling the raw material gas and using the raw material gas, the flow path can be simplified, The size can be reduced.

Specifically, the raw material gas introduced into the outlet pipe 34 at the time of filling the raw material gas is primarily filtered while passing through the second filter 26, and then flows into the second flow path 22. At this time, the manual valve 12 is in an open state. The solenoid valve 14 serves as a check valve and is opened by the pressure of the raw material gas flowing into the second flow path 22. The raw material gas flowing into the second flow path 22 flows into the first flow path 20 and is stored in the high pressure vessel 100 through the inlet pipe 32.

14, when the raw material gas is used, the raw material gas stored in the high-pressure vessel 100 flows into the first flow path 20 through the inlet pipe 32. At this time, the raw material gas is filtered while passing through the first filter (24) provided in the inlet pipe (32).

When the solenoid valve 14 is operated and the first flow path 20 is opened, the raw material gas flowing into the first flow path 20 flows into the second flow path 22 and is discharged to the outside through the outlet pipe 22 do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the embodiments set forth herein. Various changes and modifications may be made by those skilled in the art.

14: Solenoid valve 16: Overflow shutoff valve
18: pressure release device 20: first flow path
22: second flow path 24: first filter
26: second filter 32: inlet pipe
