PURPOSE: An operation valve for a flash valve is provided to prevent foreign materials from blocking an inlet hole by allowing a protrusion rod to directly clean the inlet hole. CONSTITUTION: An operation valve for a flash valve is composed as follows. An outlet hole (32) is formed on the inner center of an inlet space (31). An operation part (38) opens and closes the outlet hole. An inlet hole (33) is formed from the inlet space to the top end of the operation valve. Upper and lower packings (34, 35) are formed on the top and bottom edges of the operation valve. A tension support (50), in which a protrusion rod (52) inserted into the inlet hole is formed, is formed in the inlet space. |
