进口文丘里流量计-美国阿卡迪亚品牌

进口文丘里流量计Product description:

The utility model comprises a contraction section, a pipe changer and a diffusion section. A pipe changer is arranged at the rear of the contraction section. The pipe changer comprises a front plate, a front tube of the throat and a middle plate. The right side of the front surface of the front plate is fixedly connected with the front tube of the throat. The left side of the rear surface of the front plate is fixedly connected with the middle plate. The right side of the rear surface of the front plate is fixedly connected with the rear plate 1. The left end of the rear plate 1 is fixedly connected with the rear plate 2. The rear plate 2 is fixedly connected with the middle plate, The right side of the rear surface of the rear plate I is fixedly connected with the back pipe of the throat. The back pipe of the throat is directly opposite to the front pipe of the throat. A pipe changing structure is set inside the pipe changer. The Venturi flowmeter can change the specification of the throat before measuring the fluid flow, which can better ensure that the throat is damaged as little as possible under the erosion and wear of the fluid, and greatly improve the service life of the device.

Venturi flowmeter is a commonly used device for measuring the flow of pressurized pipeline, which belongs to differential pressure flowmeter and is commonly used for measuring the flow of air, natural gas, gas, water and other fluids. It consists of three parts, namely "contraction section", "throat" and "diffusion section", which are installed on the pipe where the flow needs to be measured. The basic measuring principle of the new generation differential pressure flow measuring instrument is a flow measurement method based on the law of conservation of energy - Bernoulli equation and flow continuity equation. The inner venturi tube is composed of a round measuring tube and a special core placed in the measuring tube and coaxial with the measuring tube. The radial outer surface of the special core body has a geometric profile similar to the inner surface of the classical Venturi tube, and forms a reducing annular flow passage gap with the inner surface of the measuring tube. The throttling process of fluid flowing through inner venturi is basically similar to that of fluid flowing through classical venturi and annular orifice. This structural feature of the inner venturi tube makes it free from sharp edge abrasion and fouling problems similar to orifice plate throttling parts during use, and can effectively adjust the flow velocity distribution gradient in the tube before throttling and various possible non axisymmetric velocity distributions (flow integration), thus realizing high accuracy and stability of flow measurement.

进口文丘里流量计Principle:

A rectangular block is set on the left side of the tube changing disk. The rear surface of the rectangular block is fitted with the rear plate II. The rear surface of the rectangular block is fixed with a connecting handle. The front end of the rectangular block is fixedly connected with a circular block. The right side of the circular block is fixedly connected with a tube changing column. The tube changing column is inserted into the side groove at the end away from the circular block. The tube changing column is matched with the side groove. The end away from the circular block is on the upper side of the leftmost throat.
