Round wedge flowmeter

Abstract

The invention belongs to the technical field of flow meters, in particular to a round wedge flow meter, and provides the following scheme that the round wedge flow meter comprises an upstream straight pipe and a downstream straight pipe, a throttling element is arranged between the upstream straight pipe and the downstream straight pipe, and outer ring plates are fixedly connected to the outer walls, located at the upper end and the lower end, of the throttling element; shaft blocks are fixedly connected to the inner wall of the outer ring plate located on the upper portion at equal intervals. The flow meter is provided with the installation self-adjusting assembly, when the flow meter is installed, the flow meter is installed at a designated position through installation bolts on an installation plate, the installation process is simple and convenient, after installation is completed, when the stretching pressure relief assembly conducts pressure adjustment in the upstream straight pipe and the downstream straight pipe, a telescopic rod on an end plate stretches out and draws back along with the telescopic rod, and the flow meter is installed conveniently. Therefore, the outside of the flow meter is stretched, dislocation deformation of the outside caused by long-term stretching of the inside of the flow meter is prevented, it is ensured that the stretching pressure relief assembly can work repeatedly, and the service life of the flow meter is prolonged.

Description

technical field

[0001] The invention relates to the technical field of flow meters, in particular to a circular wedge flow meter. Background technique

[0002] Flow measurement is one of the components of measurement science and technology. It is closely related to national economy, national defense construction, and scientific research. Doing this work well is of great importance to ensure product quality, improve production efficiency, and promote the development of science and technology. Especially in today's era of energy crisis and increasing automation of industrial production, the status and role of flowmeters in the national economy are more obvious; flowmeters are divided into differential pressure flowmeters, rotameters, Throttle flowmeter, slit flowmeter, volume flowmeter, electromagnetic flowmeter, ultrasonic flowmeter, turbine flowmeter and vortex flowmeter, etc. Classified by medium: liquid flowmeter, gas flowmeter, steam flowmeter and solid flowmeter.
