Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described, but the most therefore this utility model is limited in institute Among the scope of embodiments stated.
Seeing Fig. 1, a kind of gas pressure regulator, governor detecting system with multiple pressure stage, including the master accessing pressure-air Pipeline 1, is sequentially arranged on main line 1 the one-level pressure regulator 5 for decompression and second voltage regulation device 6, and is used for and tested pressure regulation The detection interface 8 that device, pressure regulating box or surge tank connect, detection interface 8 front end is provided with effusion meter, and effusion meter is by different size first Effusion meter 14 and second gauge 15 compose in parallel, and the two ends of first-class gauge 14 and second gauge 15 are equipped with metering valve Door;Before and after detection interface 8, two ends are equipped with temperature sensor 3 and pressure transducer 4;Wherein, second voltage regulation device 6 is provided with parallel connection Two, the entrance end of two second voltage regulation devices 6 is equipped with pressure regulator valve 7.One-level pressure regulator 5 front end is provided with one-level pressure regulation Imported valve 10, one-level pressure regulation imported valve 10 front end is sequentially provided with master control valve 2, full-bore oil water separator 16 and by the flow direction Filter 17;Main line 1 has bypass 9, the import of bypass 9 by being positioned at one-level pressure regulation imported valve 10 by picking out threeway connection Section is provided with bypass imported valve 11, and bypass 9 takes back main line 1 by accessing threeway;The access threeway of bypass 9 is positioned at second voltage regulation On the rear end pipeline section of device 6 port of export pressure regulator valve 7;Bypass 9 is also by adapter and the one-level pressure regulator 5 being provided with adapter valve 12 The port of export connect, bypass 9 is positioned at the pipeline section of adapter access point rear end and is provided with and controls valve 13.
In the present embodiment, the joint that detection interface 8 is used preferably uses stretching structure.
This detecting system is when detecting pressure regulator, pressure regulating box or surge tank, and pressure regulator, pressure regulating box or surge tank are logical Cross detection interface 8 to connect;During detection, according to pressure regulator, pressure regulating box or the nominal pressure of surge tank or operating pressure, compressed air Use different path to enter in pressure regulator, pressure regulating box or surge tank, then enter from the outlet of pressure regulator, pressure regulating box or surge tank Empty after detection outlet section.When using total head detection, i.e. nominal pressure is that the available maximum pressure of detecting system is adjusted with one-level Time between the depressor 5 output pressure upper limit, detection compressed air path is: master control valve 2 → full-bore oil water separator 16 → Filter 17 → bypass imported valve 11 → control valve 13 → first-class gauge 14 or second gauge 15 → pressure regulator, pressure regulation Case or surge tank.When using the pressure stage detection corresponding with after one-level pressure regulator 5 pressure regulation, compressed air path is used in detection For: master control valve 2 → full-bore oil water separator 16 → filter, 17 → one-level pressure regulation imported valve 10 → one-level pressure regulator 5 → Adapter valve 12 → control valve 13 → first-class gauge 14 or second gauge 15 → pressure regulator, pressure regulating box or surge tank.When When using the detection of corresponding with after second voltage regulation device 6 pressure regulation pressure stage, detection compressed air path is: master control valve 2 → Full-bore oil water separator 16 → filter, 17 → one-level pressure regulation 5 → two pressure regulator valves of imported valve 10 → one-level pressure regulator One of 7 → second voltage regulation device 6 → corresponding pressure regulator valve 7 → first-class gauge 14 or second gauge 15 → pressure regulator, Pressure regulating box or surge tank.Wherein, pressure regulator, pressure regulating box or surge tank are pressed in the selection of first-class gauge 14 and second gauge 15 The principle that rated flow adapts is selected, and preferably selects the turbine flowmeter in intelligent flow meter or Roots type flowmeter, to obtain Flow detection result accurately.
