The invention discloses an ultrasonic flowmeter pipe section and a manufacturing method. The method comprises: designing the structure, the shape, the position and the connection relation of ultrasonic flowmeter pipe section components, then processing the pipe section components through laser cutting, laser welding and the like, and finally assembling the processed components into a whole pipe section. The pipe section of the ultrasonic flowmeter comprises a pipe section body, an inserting rod pipe, an inserting rod pipe cover, an inserting rod sleeve, a flange, a round hole, a temperature measuring column and a pressure measuring column. The pipe section is provided with paired arc-shaped grooves, the inserting rod pipe is provided with arc-shaped grooves which are consistent with the arc-shaped grooves of the pipe section in number and can be welded in a matched mode, the inserting rod sleeve is welded to the inserting rod pipe, the inserting rod pipe cover is welded to the bottom end of the inserting rod pipe, and the temperature measuring column and the pressure measuring column are welded in the round hole. According to the pipe section of the ultrasonic flowmeter, a sanitarystandard seamless stainless steel pipe is adopted, laser cutting and laser welding are carried out, an automatic tool is matched, the production efficiency of a meter body is improved by one time orabove, and more energy is saved and environment friendliness is achieved.
Description
technical field [0001] The invention relates to the field of flow measurement, in particular to a pipe section structure and manufacturing method of an ultrasonic flowmeter. Background technique [0002] The surface body of the existing large-caliber ultrasonic flowmeter pipe section in my country is produced by a casting process. The production time cycle of this process has been unable to meet the customer's delivery requirements, and the casting process is complex, labor-intensive, high energy consumption, and air pollution. Serious pollution and other issues, the manufacturing process of the ultrasonic flowmeter pipe section body has become a bottleneck restricting the production efficiency of the meter body and energy saving and emission reduction. Contents of the invention [0003] In order to solve the problem of the casting process of the existing ultrasonic flowmeter pipe section surface body, the present invention designs an ultrasonic flowmeter pipe section and a...
