Abstract

The utility model relates to an ultrasonic heat meter pipe section, which mainly solve the problem that the high machining difficulty and assembly difficulty of an existing ultrasonic heat meter cause a large mounting error of a sound wave reflection structure in a pipe section and result in the low uniformity and the low precision of metering. Furthermore, the ultrasonic heat meter pipe section solves the problem that the sound wave reflection structure in the pipe section causes large particle blockage and deposition and scaling which result in metering failure. A sleeve in a split structure is formed by fastening an upper semicircular pipe and an upper semicircular pipe and axially limited by a limiting mechanism, wherein the radius of the upper semicircular pipe is smaller than that of the sleeve. The radius of the lower semicircular pipe is larger than that of the sleeve. A protruding ring is positioned outside the upper semicircular pipe. A transmitting plate and a receiving plate are positioned on the inner wall of the lower semicircular pipe. The ultrasonic heat meter pipe section in the split structure is formed by combining the two semicircular pipes, wherein the two semicircular pipes are machined respectively and then mounted together to form the pipe section. Therefore, the machining can be completed by using a simple die and the machining difficulty is effectively reduced. The machining technique is simplified and the machining cost is effectively reduced accordingly.
