It is powered-down to be connected to power supply.And booster pump is electrically connected to power supply also through the switch of configuration.
Operating procedure of the invention:
1, gas source is accessed, power supply is opened.
2, positive pressure (exhaling value) verifies:
When 100 pressure of breather valve≤20KPa of required verification, verified using U-tube；Breather valve pressure > 20KPa
When, it is verified using positive/negative pressure sensor.
1) breather valve clamps.
The breather valve 100 verified will be needed to be placed on seal disc 13, claw 12 is pushed into the connection method of the breather valve 100
Blue root.Set clamping pressure of the pressure relief value (being usually set to 0.4-0.6MPa) of pressure reducer 32 as clamping switch 15
Initiation value.After clamping switch 15 is opened, the lifting cylinder 14 of 13 lower part of seal disc pushes the seal disc 13 to begin to ramp up, in conjunction with
The claw 12 thoroughly clamps the breather valve 100 and the seal disc 13.
2) positive/negative pressure sensor calibration.
A, positive pressure is verified.Total power switch is opened, power supply indicator is bright.Positive and negative display table switching switch 261 is toggled it to
Positive pressure, while positive and negative toggle switch 21 is toggled it into positive pressure, open the switch of positive pressure display module 262, positive pressure display module
262 enter measuring state.Certificated valve 22 is slowly opened, controls speed using minute-pressure certificated valve 23 when pressure reaches 90%, directly
No longer change to positive pressure display module 262 or support staff hears the sound for breathing valve events, that is, determines to reach breather valve unlatching
Pressure closes certificated valve 22 and opens relief valve 27, and verification terminates.
B, negative pressure is verified.Total power switch is opened, power supply indicator is bright.Positive and negative display table switching switch 261 is toggled it to
Negative pressure, while positive and negative toggle switch 21 is toggled it into negative pressure.Pressurization switch pump 421 is opened, opening vacuum pump 41 starts it
Work closes pressurization switch pump 421 when 43 pressure of vacuum meter is close to -0.1MPa, and closing booster pump 41 makes it stop working,
Into negative pressure measuring state.Certificated valve 22 is slowly opened, controls speed using minute-pressure certificated valve 23 when pressure reaches 90%, directly
No longer change to negative pressure display module 263 or support staff hears the sound for breathing valve events, that is, determines to reach breather valve unlatching
Pressure closes certificated valve 22 and opens relief valve 27, and verification terminates.
3) U-tube verifies.
Positive and negative toggle switch 21 is toggled it into positive pressure, opens U-tube manometer switch 241, then slowly open certificated valve 22,
Speed is controlled using minute-pressure certificated valve 23 when pressure reaches 90%, glasses observe the raising and lowering institute of the liquid level of U-tube 24
Corresponding scale situation of change indicates that breather valve is opened when upper liquid level and the stopping variation of lower liquid level.Certificated valve 22 is closed to open
Relief valve 27, verification terminates.
At this point, the corresponding scale value of upper liquid level concave bottom and the lower liquid level concave bottom corresponding quarter of 24 liquid level of U-tube
Angle value be added together be exactly breather valve cracking pressure.Three times, taking its average value is the cracking pressure value of the breather valve for test.
U-tube test negative pressure is similar, repeats no more.
4) breather valve is dismantled.
After verification, it is first turned on relief valve 27, when system no pressure or gauge pressure are zero, closes clamping switch 15,
Lifting cylinder 14 begins to decline reset, and seal disc 13 and breather valve 100 also decline therewith, to be detached from claw 12 to breather valve
100 clamping, after lifting cylinder 14 resets completely, i.e., removable breather valve 100.
In conclusion breather valve calibration equipment of the invention exhaling for each model that can be cooperated with seal disc
It inhales valve and is able to carry out verification.Meanwhile the breather valve calibration equipment is provided with positive/negative pressure sensor and two kinds of U-typed pipe verifications
Method.Conventional positive/negative pressure sensor can verify conventional breather valve, and verification can right ± 20Kpa be below exhales for U-typed pipe
Valve is inhaled to be verified.That is, not only easy to use and wider to the verification covering surface of breather valve, checking feature is more comprehensive, has
Stronger versatility.
