Description
Technical field
The utility model relates to the multi-functional demarcation container of a kind of servicing unit, particularly a kind of gas sensor when gas sensor is produced and uses.
Background technology
What carry out measuring general to material concentration with sensor is incidence relation between sensor response and test substance concentration.And the zero point of sensor and sensitivity are in use inevitably drifted about.In order to obtain measured value more accurately, before generally all requiring measurement, sensor is demarcated.
Demarcate and need to measure sensor with the standard substance of concentration known, for liquid, solid matter, the acquisition of standard substance concentration is relatively easy, and generally weighed by analytical balance in laboratory, volumetric flask constant volume just can be accomplished.
And Demarcate Gas, be substantially the value that produces using a kind of high precision apparatus as the ruler of tolerance, be input in sensor to be calibrated, obtain the output quantity of sensor, then by mathematical method, obtain the corresponding relation between sensor constrained input.The demarcation of gas sensor, sensor, as input value, is put into the airtight container being filled with calibrating gas and is demarcated it by the known calibrating gas of normal working concentration.
Therefore, the sealing of container seems and is even more important.
At present, in existing gas sensor calibration instrument, the normal bonding jelly that adopts pastes instrument main cavity and remaining part, and bonding jelly has certain influence to gas concentration, and sealing effectiveness is bad, and this makes the demarcation of light concentration gas there is larger difficulty.In addition, existing calibrating instrument cannot reclaim gas mostly, and the marked gas be discharged in air can pollute air, even impacts demarcation the healthy of personnel.
So, for the shortcoming of existing calibrating instrument, be necessary to develop a kind of new gas sensor calibration container, while promoting instrument sealing, accomplish the protection to environment and staff.
Application number disclosed in Dec 31 in 2014 is No. 201420505880.3 Chinese invention patents, and the name of its innovation and creation is called " gas sensor calibration container ", and it comprises main cavity, left side cover plate, right side cover plate, and two cover plates are positioned at the two ends of main cavity; Left side cover plate is fixed with threeway; One end of threeway is air intake opening, and air intake opening is provided with air intake opening non-return valve; One end is gas outlet, left side cover plate offers three through holes, and gas outlet is communicated with main cavity by three through holes; One end is connected with densitometer; Right side cover plate is fixed with insulating disc and two-way; Insulating disc runs through multiple binding post, one end of binding post is positioned at main cavity inside, and one end is positioned at insulating disc outside; Right side cover plate offers through hole, and one end of this two-way is communicated with main cavity by through hole, and the other end is connected with aspiration pump, two-way is provided with gas outlet non-return valve; Aspiration pump is communicated with returnable bottle.
Although above-mentioned patented claim avoids the use of bonding jelly, and can to waste gas recovery.But with the sealing of main cavity while of needs left side cover plate, right side cover plate, aperture area is large, and sealing effectiveness is poor.In addition, commercially available O-ring seal elasticity is little, and anti-wear performance is poor, uses after a period of time, easily wearing and tearing or aging, when wearing and tearing or aging after, not easily realize, easily cause that to demarcate seal of vessel performance poor, easily leak gas, be not suitable for the demarcation of light concentration gas and toxic gas.
Meanwhile, above-mentioned calibrating instrument, function singleness, only can carry out the demarcation of gas sensor, can not carry out detecting to the fast-response of gas sensor and judge.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of good seal performance is provided, and energy Timeliness coverage poor sealing, can carry out detecting and the multi-functional demarcation container of gas sensor judged to the fast-response of gas sensor simultaneously.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The multi-functional demarcation container of a kind of gas sensor, comprise the main cavity of upper and lower both ends open, upper cover and lower capping, upper cover and lower capping are all sealed and matched by the two ends of O-ring seal and bolt and main cavity; The bottom centre of upper cover is provided with gas sensor, the top center of lower capping is provided with riser guide, the top of riser guide is fixed with open-topped protective cover, after riser guide rises, protective cover can with upper cover bottom form one gas sensor be enclosed in interior confined space; Upper cover is provided with the gas admittance valve be positioned at outside seal cavity, lower capping is provided with air outlet valve, is provided with pressure transducer in main cavity, riser guide, pressure transducer are all connected with computing machine with gas sensor.
Described riser guide, pressure transducer and gas sensor all be positioned at the computing machine infrared radio demarcated outside container and be connected.
Described air outlet valve is connected with outlet pipe, is connected with returnable bottle at the end of outlet pipe by non-return valve.
The bottom of described lower capping is provided with the some supporting legs with roller.
The top of described lower capping is fixed with mounting flange, and the bottom of described riser guide is fixed on mounting flange.
After the utility model adopts said structure, there is following beneficial effect:
1. gas sensor can be sealed in the less seal cavity of area by above-mentioned protective cover; the gas needing to carry out response detection can be first filled with outward at this little seal cavity; then; riser guide is declined rapidly; in gas gas sensor being exposed to instantaneously need to carry out response detection; thus while carrying out gas sensor calibration, demarcation and the detection of gas sensor response can also be carried out.In addition, riser guide energy automatic lifting, does not need to open demarcation container, thus can, when not affecting the sealing property of demarcating container, can repeat to form less seal cavity, can repeat test.
2. the setting of above-mentioned pressure transducer, by detecting the change of pressure in main cavity, thus monitors the sealing property of demarcation container and gives warning in advance.
3. the setting of above-mentioned returnable bottle, can reclaim waste gas, accomplishes the protection to environment and staff simultaneously.
4. above-mentioned pressure transducer and gas sensor are all connected with computing machine infrared radio, avoid the leakage problem that threading causes, and further ensure the sealing property of demarcating container.
