Today, I will introduce a national invention authorized patent-a precession vortex flowmeter. The patent was applied for by Ningbo Chuangsheng Instrument Co., Ltd., and the authorization was announced on January 25, 2017.
Content descriptionThe utility model relates to a gas flowmeter, in particular to a precession vortex flowmeter.
Background of the inventionThe precessing vortex flowmeter is widely used in petroleum, chemical, electric power, metallurgy, urban gas supply and other industries to measure various gas flows. It is currently the first choice for oilfield and urban natural gas transmission and distribution metering and trade metering. However, the existing precessing vortex flowmeter has poor anti-interference ability, low measurement accuracy, uneven pipeline flow rate and poor vibration resistance.
Summary of the inventionThe technical problem to be solved by the utility model is to provide a precession vortex flowmeter with simple and compact structure, good anti-interference ability, high measurement accuracy, uniform pipeline flow rate and good anti-vibration performance.
The utility model provides a precession vortex flowmeter, which includes a cylindrical casing 1 as a whole. Both ends of the casing are provided with connecting flanges 13, and a gas flow passage 10 is formed in the casing 1 The two ends of the gas flow channel are respectively provided with an air inlet 12 and an air outlet 11, the air inlet is fixed with a spinner 121 through a front pressure ring 122, and the air outlet 11 is fixed with a countersunk screw. In the derotator 111, the side wall of the housing 1 is provided with two first detection holes 15 coaxially arranged, and the axes of the two detection holes are perpendicular and intersect the axis of the gas flow channel. A mounting seat 14 is provided on the outer wall. The mounting seat is provided with a mounting hole 17, and a pressure sensor hole and a temperature sensor hole communicating with the gas flow channel. The pressure sensor hole is provided with a pressure sensor assembly 142, so A temperature sensor assembly 141 is provided in the temperature sensor hole.
Further, a second detection hole 16 communicating with the gas flow channel is opened on the side of the housing, and the axis of the second detection hole is perpendicular to the axis of the first detection hole. Two bosses are symmetrically arranged on the side wall of the housing, and the first detection hole is opened on the boss. Reinforcing ribs are arranged between the boss and the side wall of the shell. The spinner 121 includes a central shaft with an arc-shaped end, and a side wall of the central shaft is provided with spiral blades. The derotator 111 includes a mounting ring 110 provided with mounting holes, and blades parallel to the axis of the gas flow channel are evenly distributed on the circumference of the mounting ring.
The utility model has the beneficial effects that the structure is simple and compact, the anti-interference ability is good, the measurement accuracy is high, the pipeline flow rate is uniform, and the vibration resistance performance is good.
