Abstract
A pneumatic measurement apparatus is characterized in that a plurality of optional measurement branch circuits are arranged in parallel through a three-way valve and an inlet valve, wherein each measurement branch circuit includes a measurement branch nozzle, a pressure sensor which is used for measuring back pressure, and at least two optional orificesA1and A2which are arranged in parallel and have different aperture. This utility model can be used at the same time for people to experiment; the utility model also provides optional orifices with different aperture; and the model can realize parameter combination measurement of shape and position dimensions of the measured pieces.
Description
Technical field:
The utility model relates to experimental system.A kind of pneumatic gauging experimental setup of more specifically saying so.
Background technique:
The pneumatic gauging experimental setup is by the pressure type pneumatic gauging, nozzle in the pneumatic measuring system and the gap between the baffle plate are changed the variation that is converted into pressure in the gas circuit, pressure transducer is transformed into variation in pressure the variation of electrical signal, after the electrical signal that changes is entered virtual instrument by collection, realize the analysing and processing and the demonstration of measurement result by virtual instrument.
The pneumatic gauging method is as medium with pressurized air, utilize air at ducted flow and pressure with the physical dimension of pipeline or the characteristic of change in shape, size quantity or displacement amount variation are changed into flow or pressure variety, thereby realize high-precision measurement, because it can carry out non-contact measurement, high pressure draught sprays to workpiece surface and has self-cleaning action, less demanding and simple in structure to environmental conditions, operation and maintenance is convenient, advantages such as cost is low, so be widely used in the mechanical industry production scene, as automobile, tractor, bearing, Aero-Space, compressor, industries such as instrument and apparatus.
Utilize the output parameter of air pressure, adopt " back pressure type " air-channel system, can realize conversion, transmission, the sampling of measurement signal easily, in production practices, be widely used as pneumatic gauging.
No matter be as industrial practical application, still as experimental setup, a plurality of gaging nozzles are often arranged in the claimed apparatus, measure so that realize the Multi-parameter Combined Tool of the morpheme size of measured workpiece, and a device can be supplied with many group students and test usefulness simultaneously.In this simultaneously, for the important parameter in the pneumatic gauging---the aperture of throttle orifice, wish to have the selection of multiple different value especially, with the analysis of making comparisons intuitively.But present Related product or experimental setup do not possess these functions.A common air measuring device has only a kind of throttle orifice of aperture, though or the aperture of throttle orifice is continuously adjustable only knows its excursion and do not know pore size accurately.
Technical problem to be solved in the utility model is to avoid above-mentioned existing in prior technology deficiency, and a kind of pneumatic gauging experimental setup is provided.This device can be simultaneously for many people experimentize, can directly carry out the selection of different apertures throttle orifice, the Multi-parameter Combined Tool that also can realize the morpheme size of measured workpiece measures.
The technological scheme that the utility model technical solution problem is adopted is:
Structural feature of the present utility model is at the stable pressurized air from same voltage stabilizer, be arranged in parallel the selectable measurement branch road of multichannel by threeway and suction valve, comprise gaging nozzle in each measurement branch road, be used to measure the pressure transducer of back pressure, and at least two throttle orifice A with different apertures that are arranged in parallel
1With throttle orifice A
2
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, in the utility model, a cover stable-pressure device has a plurality of measurement branch roads simultaneously, can realize that the Multi-parameter Combined Tool of the morpheme size of measured workpiece is measured.
2, the setting of a plurality of measurement branch roads can be used it simultaneously in the utility model for many group student experimentings in education experiment.
3, the utility model passes through the selection use to the throttle orifice in different apertures, makes the student can recognize intuitively that in experiment the selection of different gas circuit parameters is to system performance curve and performance indexes.
4, the utility model is provided for measuring the pressure transducer of back pressure, converts pressure to electric weight, and by the direct reading of computer, go forward side by side line data analysis and processing have greatly improved measuring accuracy, obtain good experiment effect then.
Accompanying drawing is the utility model structural representation.
Embodiment:
Referring to accompanying drawing, present embodiment is at the stable pressurized air from same voltage stabilizer 1, be arranged in parallel the selectable measurement branch road of multichannel by threeway 2 and suction valve 3,4, comprise gaging nozzle 5 in each measurement branch road, be used to measure the pressure transducer 6 of back pressure, and at least two A with different apertures that are arranged in parallel, select use
1Throttle orifice 7 and A
2Throttle orifice 8.
Measurement branch road shown in the figure in the present embodiment has five the tunnel, and two of the throttle orifices in different apertures are arranged in each branch road.
In the present embodiment,, back pressure signal directly is converted to electrical signal in pressure transducer 6, and then can carries out data analysis and processing to this signal, and show by computer 9 by pressure transducer 6 is set.
Working principle is as follows:
Enter voltage stabilizer 1 after pressurized air process filter 11 filterings of source of the gas 10 outputs, the pressurized air of the steady pressure of voltage stabilizer 1 output enters each measurement branch road through tee union 2 and plastic flexible pipe 12.In measuring branch road A, during system works, A
11Suction valve 3 and A
12Suction valve 4 have only one open-minded so that A
1Throttle orifice 7 and A
2Throttle orifice 8 has only one to devote oneself to work.In concrete the enforcement, A can be set
1The aperture of throttle orifice 7 is 1.0mm, A
2The aperture of throttle orifice 8 is 1.5mm.Work as A
11Suction valve 3 is opened, A
12When suction valve 4 cut out, pressurized air was through A
1Throttle orifice 7 flows to A gaging nozzle 5; And work as A
12Suction valve 4 is opened, A
11When suction valve 3 cut out, pressurized air was through A
2Throttle orifice 8 flows to A gaging nozzle 5.When changing at gaging nozzle 5 and by the gap between the workpiece, also changed by the pressure p in the measured back pressure air chamber of pressure transducer 6, relevant measurement result directly shows on computer 9 thereupon.
