description The utility model relates to an orifice throttle metering device, which comprises a front measuring pipe assembly and a back measuring pipe assembly. The end part of the front measuring pipe assembly is provided with a pressure measuring hole. After a metal orifice and a front and a back metal cushions are put in the front measuring pipe assembly, the back measuring pipe assembly is connected the front measuring pipe assembly through a screw thread to firmly press the orifice, and a buckling tail end is additionally provided with a leakage prevention weld bead. The utility model has the advantages that a permanent orifice is welded in the device, the whole device is welded on a pipe assemblage, and the structure is simple. The utility model solves the problems that the replacement of the old structure for the orifice is difficult and generates leakage, etc.
