Abstract: A flow rate control device by means of the present invention comprises: a pipe-shaped first member which includes first flange units having the same shape on both ends thereof; a second member which has second flange units corresponding to the first flange unit, is connected with the first member through the surface contact of the first and second flange units, and includes a screw thread unit formed on the outer circumferential surface thereof; an adjusting member which has a female screw unit formed on the inner circumferential surface to be screwed with the screw thread unit and includes one side end which can be inserted into a position contacting the second flange unit; a moving member which is inserted and disposed in the second member and in an internal spatial part of the adjusting member, is roundly moved in an axial direction by being connected with the rotation of the adjusting member, and includes a body connected with one side end of the adjusting means through surface contact and a tip member coupled with a through-hole formed in the center of the second member so as to adjust the passing flow rate of a gas including particles flowing in the internal spatial part; and a third member which is coupled with the end of the moving member in order to be moved along with the moving member and has a third flange unit.
