Embodiment Construction

[0013] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] This example figure 1 , figure 2 , image 3 As shown, an intelligent control turbine flowmeter capable of redundant measurement includes a housing 1, an impeller 7, a signal converter 3, a regulator 4 and ultrasonic probes 5,6. The impeller 7 is set in the casing 1, the valve core of the regulating valve 4 is set in a lengthened casing 1, one end of the positioning shell 2 is connected with the end of the casing 1 where the valve core is located through a flange, and the casing 1 and The other end of the positioning shell 2 is also provided with a flange to connect with the pipeline. The adjustment valve 4 is selected as an electric adjustment valve, or a pneumatic or hydraulic adjustment valve can be selected according to the measurement and control needs. The ultrasonic probes 5 and 6 are in the same axial direction as the housing...

Abstract

The invention provides an intelligent turbine flowmeter with redundant measurement function, comprising a shell, an impeller, a signal converter and a regulating valve; wherein the impeller is arranged in the shell, the regulating valve is arranged at one end of the shell in an integration way. And the intelligent turbine flowmeter with redundant measurement function also comprises two ultrasound probes which are respectively arranged and fixed on the shell in the integration way. The invention has the beneficial effects that an integrative turbine flowmeter, regulating valve and ultrasound probe structure is adopted, redundant function of continuous measurement can also be realized even the impeller of the turbine flowmeter is in blockage fault, trade settlement dispute is reduced, maintenance response time of the turbine flowmeter is increased, and leakage points of flow measurement and control pipe line are reduced.

Description

technical field [0001] The invention relates to the field of fluid measuring devices, in particular to an intelligent control turbine flowmeter capable of redundant measurement. Background technique [0002] With the application of new energy, tap water, piped hot water and piped gas have been widely used in cities and towns, especially the application of new energy such as natural gas has brought convenience to users. At this stage, there are many types of natural gas flow measuring instruments Turbine flowmeter is one of them. Due to its compact structure, good repeatability, wide range, high precision, small zero drift of components, and good anti-interference ability, the turbine flowmeter has been widely used in the field of natural gas flow measurement. Applications. However, the shortcomings of ordinary turbine flowmeters are also becoming more and more prominent in the measurement process of natural gas. The main reason is that the impeller of the turbine flowmeter ...
