PURPOSE: A constant pressure-based discharging type spraying unit is provided to secure constant pressure for spraying liquid by arranging a valve for connecting and blocking an inlet and an outlet. CONSTITUTION: A constant pressure-based discharging type spraying unit includes a body(100), a pivoting motion valve(200), a distributing part(210), and a non-distributing part(220). The body includes an inlet(111), an outlet(122), and a space part(121) between the inlet and the outlet. The pivoting motion valve is arranged in the space part. The pivoting motion valve is connected to a driving unit(300). The distributing part is formed at the valve in order to connect the inlet and the outlet of the body. The non-distributing part is formed at the valve in order to block the inlet and/or the outlet of the body when the valve is being pivoted. The connecting and the blocking of the inlet and the outlet of the body are switched by the pivoting motion of the valve. |
