Description
Technical field
The utility model relates to a kind of thermostatically controlled pressure detection structure.
Background technology
Film sample is being carried out in the detection of gas permeability, because sample is under different temperature, its gas infiltration capacity has very big-difference, so in order to obtain the permeance property data of sample under different temperatures, need test under different temperatures sample.In order to make sample reach different temperature, generally be that test chamber is carried out temperature control, come sample is carried out temperature control by test chamber.
Infiltration enters the enclosure space of being made up of test chamber, gas path pipe, pressure transducer, valve by the gas of sample, and the pressure of this enclosure space of pressure sensor monitoring changes.Traditional method is because just to the test chamber temperature control, the space that other element is formed is a room temperature, so the temperature of whole enclosure space is inconsistent, has directly influenced the pressure monitoring precision.
The utility model content
The utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of have simple in structure, easy to use, the thermostatically controlled pressure detection structure of monitoring accuracy advantages of higher.
For achieving the above object, the utility model adopts following technical scheme:
A kind of thermostatically controlled pressure detection structure, it comprises a constant temperature enclosure, is provided with thermostatically-controlled equipment in constant temperature enclosure; Proving installation is installed in the constant temperature enclosure and with pressure test device and is connected; Proving installation also is connected with a regulating device.
Described thermostatically-controlled equipment is heating element and the cooling module that is installed in the constant temperature enclosure inwall.
Described proving installation comprises test epicoele and test cavity of resorption, and the test cavity of resorption is connected with pressure transducer by gas circuit, also is provided with valve simultaneously on gas circuit; The test epicoele is connected with regulating device.
Described regulating device is and the screw rod that is connected of test epicoele, its other end pass constant temperature enclosure and with compress knob and be connected.
Thermostatically controlled pressure detection structure of the present utility model, it comprises constant temperature enclosure, test chamber, pressure transducer, valve, gas path pipe, compresses knob, screw rod.Test chamber, pressure transducer, valve, gas path pipe all are positioned in the constant temperature enclosure, compress knob and screw rod reaches outside the constant temperature enclosure.Described constant temperature enclosure is furnished with the heating and cooling element.Described constant temperature enclosure, test chamber, pressure transducer, valve, gas path pipe, their inner space communicates, and closes the back at valve and forms enclosure space.
Advantage of the present utility model is:
1, can realize the constant unanimity of test structure temperature.
2, realize conveniently, simple in structure.
3, cost is low.
Description of drawings:
Fig. 1 is the utility model structural drawing, for there not being clamping sample state;
Fig. 2 is the utility model structural drawing, is clamping sample state.
Wherein, 1. constant temperature enclosure; 2. screw rod; 3. compress knob; 4. test epicoele; 5. test cavity of resorption; 6. gas path pipe I; 7. pressure transducer; 8. gas path pipe II; 9. valve; 10. heating element; 11. cooling module; 12. sample.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
In Fig. 1-Fig. 2, heating element 10 and cooling module 11 are installed in the constant temperature enclosure 1, guarantee that constant temperature enclosure can meet the requirements of test temperature, and keep temperature constant.Test epicoele 4, test cavity of resorption 5, gas path pipe I 6, gas path pipe II 8, pressure transducer 7, valve 9 are installed in the constant temperature enclosure 1, guarantee these component temperature unanimities.Screw rod 2 one ends are installed on the test epicoele 4, and the other end stretches out outside the constant temperature enclosure 1, and installation compresses knob 3, handled easily.
After sample 12 being placed between test epicoele 4 and the test cavity of resorption 5, rotatably compress knob 3, drive screw rod 2 and compress test epicoele 4, test epicoele 4 and test cavity of resorption 5 are fitted closely, gas is penetrated into test cavity of resorption 5 from test epicoele 4 by sample 12, under valve 9 closed conditions, test cavity of resorption 5, gas path pipe I 6, gas path pipe II 8, pressure transducer 7, valve 9 form enclosure space, the gas that is penetrated into test cavity of resorption 5 is accumulated in this enclosure space, by the pressure variation of pressure transducer 7 these enclosure spaces of monitoring.
Because this enclosure space is constant temperature everywhere, so changing, the pressure that pressure transducer 7 monitors is not subjected to ectocine, guaranteed measuring accuracy.
