Abstract

The utility model belongs to the scope of metering and detecting and particularly relates to a calibrating device of a float flowmeter. The calibrating device comprises a pool, a water pump, a voltage stabilization container, a closing valve, a thermometer, a pressure meter, a regulating valve, an expansion device and a standard container, wherein the pool is connected with the water pump by a pipeline; the water pump is connected with the voltage stabilization container by a pipeline; the voltage stabilization container is connected with the closing valve by a pipeline; the expansion device is connected with the regulating valve; and the pool is connected with the standard container by a pipeline. The calibrating device is characterized in that a densitometer is arranged between the closing valve and the expansion device; and a pneumatic three-way valve is arranged on a pipeline of the standard container. The utility model solves the problem that the special calibrating device of the float flowmeter does not exist at present, and the calibrating device has better calibrating precision.

Description

The suspended body flowmeter calibrating installation
Technical field:
The utility model belongs to the category of Measuring and testing, is specifically related to a kind of suspended body flowmeter calibrating installation.
Background technology:
The total class of suspended body flowmeter is a lot, comprise glass tube suspended body flowmeter, metal pipe float flow meter, spinner-type flowmeter, its principle of work of suspended body flowmeter is a fluid when flowing through tapered tube from bottom to top, produces differential pressure between the upstream and downstream of float again, and float rises under the effect of this differential pressure.When the suffered differential pressure of float, gravity, buoyancy and viscous force make a concerted effort to be zero the time, float is in the equilibrium position.Therefore the lifting height of flow and float, promptly and exist certain proportionate relationship between the circulation area of flowmeter.
Up to the present also do not have special-purpose suspended body flowmeter correcting device, people generally adopt the water meter calibration device to calibrate suspended body flowmeter, and accuracy is relatively poor.
Summary of the invention:
A kind of accuracy suspended body flowmeter calibrating installation preferably that aims to provide of the present utility model.
The technical solution of the utility model is: comprise pond, water pump, pressurizing vessel, stop valve, thermometer, pressure gauge, variable valve, expansion bend, volumetric standard, the pond connects water pump by pipeline, water pump connects pressurizing vessel by pipeline, pressurizing vessel connects stop valve by pipeline, expansion bend connects variable valve, the pond connects volumetric standard by pipeline, it is characterized in that a densitometer is installed between stop valve and expansion bend, and a Pneumatic three-way is installed on the pipeline of volumetric standard.
In order to adapt to the installation of different types of suspended body flowmeter, realize installation to different types of suspended body flowmeter by using various reducer pipes.
The utility model has solved the problem that does not up to the present also have special-purpose suspended body flowmeter correcting device, and the accuracy of calibration is better.
