At this time, the electromagnetic solenoid valve is provided with a valve at a lower portion thereof, and the gas discharged to the gas supply hole is discharged through the valve by the operation of the electromagnetic solenoid valve.

Here, the plurality of the solenoid valves may be operated to discharge the gas to the predetermined gas supply hole among the plurality of gas supply holes, or to discharge the gas simultaneously through the plurality of gas supply holes.

However, in the above-described Patent Document 1, it is troublesome to connect an electromagnetic solenoid valve to each gas supply hole of the main gas supply pipe. The gas supply hole of the main gas supply pipe must be formed so as to correspond to the number of the electromagnetic solenoid valves, Particularly, when the gas supply hole of the main gas supply pipe is insufficient, it is inconvenient to replace the main gas supply pipe and the replacement cost is increased. When the main gas supply pipe is damaged, the plurality of electromagnetic solenoid valves are separated and re- In particular, since the volume of the main gas supply pipe and the solenoid valve is increased, the installation space is limited and the reliability of the product is deteriorated.

That is, a blocking plate 103a is integrally formed on the connection passage 103 of the main body 100 installed at the end of the main body 100 to seal the connection passage 103, 104 to seal the connection passage 103 by inserting the hermetic member 105 therein.

The solenoid valve 200 installed in each of the main bodies 100 is opened to allow the inflow passage 101a, the connecting passage 103 and the discharge passage 102a of the main body 100 to communicate with each other, The gas is supplied through the gas inlet 101 of the main body 100 provided at the tip of the main body 100 in a state where the stepping motor valve 300 is operated to open the discharge path 102a, do.

Part of the gas supplied through the inflow path 101a of the gas inflow port 101 passes through the discharge path 102a opened by the stepping motor valve 300 and is discharged to the gas discharge port 102 And some other gas is supplied to the gas inlet 101 of the other main body 100 through the connection passage 103. [

At this time, the gas supplied to the other gas inlet 101 is discharged to the gas discharge port 102 of each of the main bodies 100 in the same manner as described above, and supplies gas to the other main body 100.

A part of the gas supplied to the main body 100 provided at the end of the plurality of the main bodies 100 is discharged to the outside of the main body 100 through the gas discharge port 102 as described above, Is blocked by the sealing plate 103a formed in the connecting passage 103 or blocked by the hermetic member 105 coupled to the engaging groove 104 and stays on the connecting passage 103. [
