PURPOSE: A floating type orifice unit having a concentric multiple cylindrical chambered structure in a storage tank of a district heating is provided to minimize upward and downward vortex by horizontally flowing in and out of high temperature hot water through an inflow part. CONSTITUTION: A floating type orifice unit having a concentric multiple cylindrical chambered structure in a storage tank of a district heating comprises a guide pipe, a slider pipe(47), multiple float parts(30), a circular center plate(32), a supporting plate(31), a connection pipe(35), and a high temperature water inflow part. The guide pipe is erectly coupled to the ceiling center part of a storage tank. The slider pipe has a through-hole(46). The center plate is installed at the bottom o the float parts. The supporting plate is coupled to the center plate by multiple partition plates(34) to maintain a certain gap with the center plate. The connection pipe is coupled to the bottom center part of the supporting plate and is communicated with the through-hole. The high temperature water inflow part is installed in between the supporting plate and the center plate and has spaces(33) for flowing in and out of high temperature water.
