Embodiment Construction

[0018] exist figure 1 In the flow body shown, the main body 1 is a stainless steel flat cuboid structure, that is, the top surface and the bottom surface of the main body 1 are parallel to each other, the two side surfaces are parallel to each other, and the front and rear surfaces are both arc-shaped convex surfaces. The convex surface is an upright arc-shaped surface with a central angle of 40-60°, and the tangent angle between the chord and the arc between the side surface of the main body 1 and the convex surface is greater than 130°.

[0019] Of course, the main body 1 can also be a steel structure with three sets of opposite faces corresponding to parallel and perpendicularly intersecting with its faces.

[0020] Only on the body 1 of the above-mentioned square body structure, it is suitable to open the flow channel of the square or rectangular hole with the largest flow area, and to ensure that the overall size and span of the body are minimized.

Abstract

The invention relates to a steady-state circulation body for a vortex shedding flowmeter, which structurally comprises a body, wherein a flow channel for the measured liquid to pass and two probe mounting holes which are communicated with the flow channel are arranged on the body, a vortex generating body is arranged in the flow channel, the body is a square body with paralleled top and bottom surfaces and paralleled side surfaces, and the flow channel is a square hole which penetrates through the body from the front and the back surfaces. The steady-state circulation body for the vortex shedding flowmeter overcomes the technical defects of unsteady observation and metering and slightly bigger integral structural size of the existing vortex shedding flowmeter, the size of a breaking-in pipeline can be correspondingly reduced during the installation process, the turbulent flow and the disturbance of the measured liquid can be reduced when the measured liquid passes through the flow channel of the circulation body, so the flow stablization effect is realized, and the stabilization of the vortex and the detection is realized.

Description

technical field [0001] The invention relates to a component of a vortex flowmeter, in particular to a steady flow body for a vortex flowmeter. Background technique [0002] The plug-in vortex flowmeter uses the principle of "Kamen vortex street" to measure the fluid flow rate in the center of the pipeline by detecting the vortex generated by the vortex generator's upstream surface intercepting the fluid medium in the pipeline under test, and then calculate the An inductive flow metering device for pipeline fluid flow. Its structure includes several parts such as a meter head, an ultrasonic detection system, a plug-in rod, a sealing connection component and a flow body; wherein, the flow body is the part that is inserted into the measured pipeline through the external ball valve on the measured pipeline to detect the flow rate. [0003] The existing flow body includes a conical body made of double-layer cone sleeves, and a cylindrical flow channel and two upper and lower pos...
