Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of vacuum pressure valve automatic Verification proving installation as shown in Figure 1, comprise low-pressure gas storage tank 1, vacuum pressure valve 6 to be verified and operating side computer 9, be communicated with through pipeline 2 between low-pressure gas storage tank 1 and vacuum pressure valve to be verified 6, the pipeline of this pipeline 2 is provided with check valve 3, vacuum pump 12, pressure transducer 11 and atmospheric valve 4, vacuum pump 12, on pressure transducer 11 and the pipeline of atmospheric valve 4 between check valve 3 and vacuum pressure valve to be verified 6, pressure transducer 11 is formed with operating side computer 9 and is electrically connected, the circuit of pressure transducer 11 and operating side computer 9 is provided with the data processor 10 amplified for data, this proving installation also comprises management end computer 7, and this management end computer 7 is formed with operating side computer 9 and is electrically connected, and circuit between management end computer 7 and operating side computer 9 is provided with the server 8 for exchanges data.Proving installation also comprises clamping platform 5, and vacuum pressure valve 6 clamping to be verified is arranged on clamping platform 5, vacuum pressure valve 6 to be verified can be stably fixed on clamping platform 5 like this.
Operating side computer 9 is provided with special software, and for control data processor 10 image data, pressure transducer 11 is sent into data processor 10 and carried out amplification process after converting pressure signal to electric signal, and is uploaded to operating side computer 9; Management end computer 7 and operating side computer 9 carry out exchanges data by server 8.Operating side computer 9 is touching-type monitor, and operating side computer 9 also installs special software.Pipeline between check valve 3 and vacuum pressure valve to be verified 6 is also provided with pointer pressure.
The parameter of vacuum pressure valve 6 to be verified and essential information (latus rectum of applying unit information, manufacturer's information, check bit information and vacuum pressure valve, pressure level range, the date of production, requirement exhalation pressure and suction pressure etc.) are by carrying out typing in verification management end computer 7 (by installing special software), and writing in the database on server 8, task to be verified is read in, is presented on touch display by verification operation end computer 9 (being provided with special software).
Store the verification medium (nitrogen or pressurized air) of pressure at about 0.2MPa in low-pressure gas storage tank 1, verification operation starts, and vacuum pressure valve 6 clamping to be verified is on clamping platform 5; Open certificated valve, low pressure verification medium (nitrogen or pressurized air) enters in vacuum pressure valve 6 to be verified, the pressure that pressure transducer 11 is recorded rises gradually, pressure transducer 11 accesses on the pipeline be connected with vacuum pressure valve 6 to be verified, therefore synchronously can record the real-time pressure in vacuum pressure valve 6 to be verified or vacuum tightness; When pressure reaches its exhalation pressure, vacuum pressure valve 6 to be verified is opened, and is breathed out by verification medium, closes certificated valve immediately.Now, boosting curve will show flex point (becoming unexpected decline from rising), and this flex point is vacuum pressure valve 6 to be verified and breathes out pressure, and will be automatically recorded (special software completes).After exhalation piezometry, open after verification medium is all discharged by exhaust-valve and close again, then vacuum pump 12 is opened, the vacuum tightness that now pressure transducer 11 records will rise gradually, when vacuum tightness reaches its suction pressure, vacuum pressure valve 6 to be verified is opened, and outside air is inhaled into, and closes certificated valve immediately.Now, curve of vacuum will show flex point (becoming unexpected decline from rising), and this flex point is vacuum pressure valve 6 suction pressure to be verified, and will be automatically recorded (special software completes).After suction pressure measures, then open exhaust-valve vacuum breaker.After test terminates, test data and result, by write into Databasce, read in by verification management end computer 7 (installation special software) documents such as automatically generating verification report, calibration tails.Verification management end computer 7 (installation special software) can carry out Classification Management to all Detection tasks, and all verification tasks all can be queried and review.Touch display faced by checker, does not need to carry out any typing, is shielded and completes verification operation, very hommization by point touching.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
