And the flow rate piece 10 is configured to adjust the opening and closing amount of the second valve seat 7 by using the orifice passage groove 10-1 symmetrically provided on the outer peripheral surface thereof.

5, the flow piece 10 has a pair of orifice passage grooves 10-1 symmetrically formed on the outer peripheral surface thereof, and the orifice passage groove 10-1 is formed by a second valve So that the fluid that is divided by the sheet 7 and introduced into the first fluid channel 2 can be discharged to the third fluid channel 4.

Particularly, the orifice passage groove 10-1 of the flow piece 10 has a wider shape toward the lower side, and as the flow piece 10 rises and is positioned on the upper side of the second valve seat 7, And the outflow flow rate through the three-fluid flow path 4 is designed to be large.

The three-way valve according to the present invention is configured such that the cylinder 30 is inserted through the connection port 5 of the valve body 1 and is seated on the upper and lower seating surfaces 5-1 and 5-2, 30 are formed such that a flow path connected to the connection flow path 6 is formed and a lower surface forms the first valve seat 31. [

1 to 3, when the valve shaft 20 is driven to rise, the three-way valve according to the present invention moves the valve disc 11 to the first valve (not shown) of the cylinder 30 through the connecting passage 6, So that the first valve seat 31 is completely closed while closely contacting the seat 31.

In particular, the three-way valve according to the present invention is characterized in that the valve disc 11 of the valve shaft 20 is attached to the first valve seat 31 of the cylinder 30, The orifice passage grooves 10-1 are opened to the maximum while the flow rate piece 10 is lifted and the maximum flow rate is discharged through the third fluid passage 4.
