PURPOSE: A cone valve is provided to minutely control flow rate by rotating a flow rate control body with a screw coupling method. CONSTITUTION: A cone valve comprises a first body(10), a flow rate control body(20), and a second body(30). A flow path(11) is longitudinally formed in the first body. A cone part(12) is formed inside the flow path. The flow rate control body controls flow rate through an interval with the cone part while rotating in a state where one end of the flow rate control body is coupled to the first body The second body is connected to a pipe while closing the other end of the flow rate control body.
