Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of vacuum pressure valve automatic Verification proving installation, comprise low-pressure gas storage tank 1, vacuum pressure valve 6 to be verified and operating side computer 9, between low-pressure gas storage tank 1 and vacuum pressure valve to be verified 6, through pipeline 2, be communicated with, on the pipeline of this pipeline 2, be provided with check valve 3, vacuum pump 12, pressure transducer 11 and atmospheric valve 4, vacuum pump 12, pressure transducer 11 and atmospheric valve 4 are on the pipeline between check valve 3 and vacuum pressure valve to be verified 6, pressure transducer 11 forms and is electrically connected to operating side computer 9, on the circuit of pressure transducer 11 and operating side computer 9, be provided with the data processor 10 amplifying for data, this proving installation also comprises management end computer 7, and this management end computer 7 forms and is electrically connected to operating side computer 9, and is provided with the server 8 for exchanges data on the circuit between management end computer 7 and operating side computer 9.Proving installation also comprises clamping platform 5, and vacuum pressure valve 6 to be verified clamps and 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 controlling data processor 10 image data, pressure transducer 11 converts pressure signal to send into data processor 10 after electric signal and amplify processing to, and is uploaded to operating side computer 9; Management end computer 7 carries out exchanges data with operating side computer 9 by server 8.Operating side computer 9 is touching-type monitor, and operating side computer 9 is also installed special software.On the pipeline between check valve 3 and vacuum pressure valve to be verified 6, be 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 carried out typing in verification management end computer 7 (by special software is installed), and write in the database on server 8, verification operation end computer 9 (special software is installed) reads in task to be verified, be presented on touch display.
In low-pressure gas storage tank 1, store pressure at the verification medium (nitrogen or pressurized air) of 0.2MPa left and right, verification operation starts, and vacuum pressure valve 6 clampings to be verified are 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 being connected with vacuum pressure valve 6 to be verified, therefore can synchronously record real-time pressure or the vacuum tightness in vacuum pressure valve 6 to be verified; When pressure reaches its exhalation pressure, vacuum pressure valve 6 to be verified is opened, and verification medium is breathed out, and closes immediately certificated valve.Now, the curve that boosts will show flex point (becoming unexpected decline from rising), and this flex point is vacuum pressure valve 6 exhalation pressure to be verified, and will be automatically recorded (special software completes).After exhalation piezometry, open after exhaust-valve is all discharged verification medium and close again, then open vacuum pump 12, 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 immediately certificated valve.Now, curve of vacuum will show flex point (becoming unexpected decline from rising), and this flex point is vacuum pressure valve 6 suction pressures to be verified, and will be automatically recorded (special software completes).After suction pressure is measured, then open exhaust-valve vacuum breaker.After test finishes, test data and result, by write into Databasce, are read in the documents such as automatic generation verification report, calibration tails by verification management end computer 7 (installation special software).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.The touch display that checker faces, does not need to carry out any typing, is shielded and is completed verification operation, very hommization by point touching.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on instructions, must determine its technical scope according to claim scope.
