Description
Technical Field
The utility model belongs to the technical field of the flowmeter, especially, relate to a vortex shedding flowmeter.
Background
The vortex shedding flowmeter is a volume flowmeter which is produced according to the Karman vortex shedding principle and is used for measuring the volume flow, standard condition volume flow or mass flow of gas, steam or liquid. The flow meter is mainly used for measuring the flow of industrial pipeline medium fluid, such as various media of gas, liquid, steam and the like. When the existing vortex shedding flowmeter is used for measurement, when the flow rate of fluid in a pipeline is low or the flow speed is low, the measurement precision of the fluid is influenced, and the actual measurement range cannot be met.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the weak point among the prior art, provide a simple structure, job stabilization, simple operation, measure accurate vortex shedding flowmeter.
In order to solve the technical problem, the utility model adopts the following technical scheme: a vortex shedding flowmeter comprises a meter body, wherein connecting flanges are fixedly connected with two ends of the meter body, the meter body comprises an adjusting pipe and a measuring pipe, the diameter of the measuring pipe is smaller than that of the adjusting pipe, a vortex generating body is arranged in the measuring pipe, a meter head is arranged at the upper part of the measuring pipe through a connecting rod, a detection probe extending into the measuring pipe is arranged at the lower end of the connecting rod and is positioned at one side of the vortex generating body, an inner connecting pipe is hermetically and slidably connected with the inner wall of the adjusting pipe, an end cap is fixedly connected with the inner wall of the inner connecting pipe through a plurality of mounting rods, one end of the end cap close to the measuring pipe is arranged into a conical structure, a flow guide hole is formed in the center of the end cap, an outer connecting pipe is slidably connected with the outer connecting pipe, a limiting groove positioned between the outer, the outer wall of the adjusting pipe is in threaded connection with adjusting nuts which are respectively positioned at two ends of the outer connecting pipe.
The lower end of the vortex generating body is embedded in the measuring tube, the upper portion of the measuring tube is provided with a gland used for fixing the vortex generating body, and the gland is fixedly connected to the measuring tube through a countersunk screw.
And a sealing gasket is arranged between the gland and the upper end of the vortex generating body.
Adopt above-mentioned technical scheme, the utility model discloses when the work is used, can adjust through the velocity of flow and the flow of regulating tube to the fluid, can twist and move adjusting nut to the outer connecting pipe that slides drives the interconnection and takes over the removal, makes the end cap be close to or keep away from surveying buret and remove, thereby reduces or the increase gets into the interior fluidic flow of surveying buret, realizes accurate measurement.
