Abstract
A differential pressure pipeline flow resistance testing device is a gauging facility which is designed according to a way of non-fluid-flow discharge direct test to have a test of a pipeline flow resistance condition through a pressure difference. The device substantially makes use of a high precise force sensitive sensor component and is realized through a digital display via to replace a traditional test operation method which allows eyes of humans to participate in distinguishing calibration. The device achieves purposes of greatly increasing distinguishing precision and testing speed for the test of the pipeline flow resistance condition.
Description
Technical field:
The utility model relates to pipeline flow resistance measuring technology.
Background technology:
At present, the proving installation of the pipeline flow resistance that industrial and mining enterprises adopt mainly contains two kinds of fluid flow method and gas flowrate methods, whether for example: refrigerator factory and air conditioner will use the flow resistance of capillary restrictor parts in the refrigeration system will be carried out the work of quantitative test, qualified as the flow resistance state capillaceous of flow controller to determine.Current, in above-mentioned two kinds of methods of measuring pipeline flow resistance state, the still gas flowrate method of maximum usefulness.Because no matter from measuring accuracy and test speed, or test environment, it all is better than the fluid flow method.Yet the deficiency of gas flowrate method maximum remains the flow scale that the naked eyes that can't break away from personnel selection are differentiated air-gauge.As everyone knows, people's naked eyes resolving accuracy can be not high, with the resolving accuracy of high-tech sensor, can't compare, and the latter will be far longer than the former.
Summary of the invention:
The purpose of this utility model is: propose the proving installation that a kind of naked eyes that replace the people by the high-resolution element participate in the pipeline flow resistance state that scale differentiates, to improve the measuring accuracy and the test speed of pipeline flow resistance state to greatest extent.
Key problem in technology of the present utility model is main testing element and the test process that its adopts: by force-sensing sensor pressure difference data is carried out after the acquisition process its flow resistance state of digital display again.---people's naked eyes only are used to differentiate 0 to 9 numeral, rather than resolution calibration.
The utility model is achieved in that it is in the high-pressure air source part that contains the nitrogen cylinder of being with voltage stabilizer at least with contain at least on the basis of pressure reduction transmitter sampling display part, it is characterized in that: its main part is made up of at least one known pipeline damper and tested pipeline, and known pipeline damper and tested pipeline all are to be serially connected in the main gas circuit of the direct dispensing of airspace to external world nitrogen; Two ends of known pipeline damper are respectively equipped with two force samples points, and link to each other with two input interfaces of pressure reduction transmitter; The pressure reduction transmitter links to each other with A/D converter, and the latter links to each other with device for digit-displaying.
The utility model is compared with the prior art: owing to adopted the naked eyes that replace the people by high-resolution element (force-sensing sensor) to participate in the proving installation that scale is differentiated, this has just created condition for the measuring accuracy and the test speed that increase substantially pipeline flow resistance state, and also to open out-of-the-way more advanced by way of having created condition again for the test of pipeline flow resistance state simultaneously.
Description of drawings:
Figure has illustrated its test pipeline to connect existing road as an embodiment of the present utility model.
1: tensimeter; 2. be with the nitrogen cylinder of voltage stabilizer; 3: valve; 4: known pipeline damper; 5: tested pipeline; 6: the pressure reduction transmitter that constitutes by force-sensing sensor; The 7:A/D converter; 8: device for digit-displaying; M: high pressure sampled point; N: intermediate pressure sampled point; A: high-pressure steam source part; B: sampling display part; C: part of detecting.
Embodiment:
As long as the flow resistance of tested pipeline 5 changes to some extent, known pipeline damper 4 will change with the flow resistance sum of tested pipeline 5, under the constant situation of the pressure of higher nitrogen cylinder 2 output and lower atmospheric pressure, also can change with the nitrogen flow of tested pipeline 5 is inevitable through known pipeline damper 4, to make intermediate pressure n also change, at this moment, represent signal that the high pressure sampled point m of nitrogen cylinder 2 output pressures and intermediate pressure sampled point n gather through relatively and after by A/D converter 7 conversions, will be presented in above the device for digit-displaying 8 with digital form, supply people's naked eyes to read.---at this moment, there is not the problem of resolution calibration value in people's naked eyes, but only allow the naked eyes performance read the function of numeral.
The success or failure that the utility model is implemented depend primarily on the result who obtains and debug of high-precision force photosensitive elements, and these 2 is the success that is easy to get.
