A ivalvu yokulinganisayivalvu enokukwazi ukulawula ukuhamba kwamanzi ngokuchanekileyo ngokutshintsha indawo enqamlezileyo apho ulwelo ludlula khona.
Umgaqo wokusebenza weivalvu yokulinganisa: umngxuma wetshaneli yokuhamba ejikelezayo ochanekileyo, isiqu sevalvu ejikelezileyo echanekileyo, kunye nesiphatho seqhosha esishukumisa isiqu sevalvu ejikelezileyo phezulu nasezantsi ukuze sihambelane nomngxuma wetshaneli yokuhamba ejikelezayo ukuze kufezekiswe ulawulo oluchanekileyo lwendawo enqamlezileyo ye-annular apho ulwelo ludlula khona. Ukuze kufezekiswe ulawulo oluchanekileyo lwendawo enqamlezileyo yokuhamba, umsonto wokudlulisa ochanekileyo nawo uyafuneka. Kwiimfuno ezichanekileyo ngakumbi, isiphatho seqhosha esine-vernier sinokubonelelwa, esahlula ijika elinye le-pitch stroke kwi-1/25.
IHikelok inokubonelela ngothotho lwezineiivalvu zokulinganisa, MV1~MV4, kunye neeparameter ezithile ngolu hlobo lulandelayo:
| Suluhlu | I-Orificengaphakathi. (mm) | I-Stem Taper | I-CV(FiphantsiCii-oefficients) |
| 0.032(0.81) | 1° | 0.004 | |
| 0.056(1.42) | 3° | 0.03 | |
| 0.128（3.25） | 6° | 0.15 | |
| 0.062(1.6) | 2° | 0.04 |
IHikelok ineziphatho zeknob ezine-vernier.
Iivalvu zokulinganisazisetyenziswa kakhulu kwisampulu yelabhoratri, i-chromatography, uhlalutyo, kunye nokusetyenziswa okufuna ulawulo oluchanekileyo lokuhamba kwamanzi.
UHikelok, umenzi wezixhobo zomculo oqeqeshiweyoiivalvukwayeizixhobo zokufakelwa.
