Standard throttling device installation and maintenance,

Abstract: For the installation and maintenance of standard throttling devices, the information is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Standard throttling device: standard orifice plate, standard nozzle and venturi tube, and other non-standard throttling devices: circular orifice plate, 1/4 round nozzle, double orifice plate, V cone, wedge flowmeter, etc. The standard throttling device must be calibrated by real flow before leaving the factory. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the installation and maintenance of standard throttling devices, and the article details. Standard throttling device: standard orifice plate, standard nozzle and venturi tube, and other non-standard throttling devices: circular orifice plate, 1/4 round nozzle, double orifice plate, V cone, wedge flowmeter, etc. The standard throttling device must be calibrated by real flow before it can be used. Throttling device installation details: generally pay attention to the following aspects: the right-angle side of the throttling hole should face the direction of fluid flow; the throttling part should be concentric with the pipeline; The first 20D and the later 5D can generally meet the normal measurement requirements for the length of the straight pipe section (except for elbows, valves, and sudden changes in pipe diameter before and after the throttle) When the 3-section device is installed on a horizontal pipeline, the measured gas should be measured in the pipeline. Take the pressure from the top, measure the steam and liquid, and take the pressure horizontally on the center line of the side of the pipeline, and never take the pressure from the bottom of the pipeline; the laying method and the laying slope of the pressure guiding pipe are different from the measuring medium, and the transmitter is installed on the pipeline. , the position below is different. In a word, the installation of the throttling device is a highly professional technical work, so professional technicians must be invited for on-site guidance during installation. 4 Strengthen maintenance and maintenance After the throttling device is put into use, pay attention to its own leakage and the leakage and blockage of the primary valve and pressure guiding pipeline, carry out regular or irregular inspections, and deal with problems in time. Especially for steam measurement, the working pressure of the steam pipe network changes greatly in winter and summer, and pipes, throttling devices, flanges, etc. are affected by thermal expansion and contraction, which can easily cause leakage and lead to measurement inaccuracy. If the leakage is not handled in time, the leakage will gradually increase. Even damage the throttling device. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Standard throttling device installation and maintenance,'
