Izinzuzo kanye nokubi ekukhethweni kwe-valve yesango

Phakathi kwezinhlobo ezahlukene zama-valve,ama-valve esangoyizona ezisetshenziswa kakhulu.I-valve yesango isho i-valve ipuleti lesango layo elihamba liqonde mpo ye-eksisi yesiteshi.Ngokuyinhloko isetshenziselwa ukusika i-medium epayipini, okungukuthi, ivule ngokugcwele noma ivalwe ngokugcwele.Ngokuvamile, ama-valve esango awakwazi ukusetshenziswa njenge-throttling.Ingasetshenziselwa ukushisa okuphezulu nokucindezela okuphezulu, futhi ingasetshenziselwa imidiya ehlukahlukene ehlukene.Amavalvu esango ngokuvamile awasetshenziswa kumapayipi athutha udaka noketshezi lwe-viscous.

I-valve yesango inezinzuzo ezilandelayo:

1. Ukumelana noketshezi oluncane;

2. I-torque edingekayo yokuvula nokuvala incane;

3. Ingasetshenziswa ephayiphini lenethiwekhi eyindandatho lapho okuphakathi kugeleza ezinhlangothini ezimbili, okusho ukuthi, ukugeleza komzila akukhawulelwe;

4. Uma ivuleke ngokugcwele, ukuguguleka kwendawo evalekayo yisisetshenziswa esisebenzayo kuncane kunokwevalvu yembulunga;

5. Isimo silula futhi inqubo yokukhiqiza ingcono;

6. Ubude besakhiwo buncane kakhulu.

Ngenxa yokuthi ama-valve esango anezinzuzo eziningi, asetshenziswa kabanzi.Ngokuvamile, ipayipi elinobukhulu obujwayelekile ≥ DN50 lisetshenziswa njengethuluzi lokunqamula okuphakathi, futhi ngisho nakwamanye amapayipi anobubanzi obuncane (njenge-DN15~DN40), amanye amavalvu esango asagciniwe.

Ama-valve esango nawo anobubi obuthile, ikakhulukazi:

1. Ubukhulu obuphelele nobude bokuvula kukhulu, futhi indawo yokufaka edingekayo nayo inkulu.

2. Phakathi nenqubo yokuvula nokuvala, kukhona ukungqubuzana okuhlobene phakathi kwezindawo zokuvala, futhi ukugqoka kukhulu, futhi kulula ngisho nokubangela imihuzuko.

3. Ngokuvamile, ama-valve esango anezipheya ezimbili zokuvala, okufaka ubunzima obuthile ekucubunguleni, ekugayeni nasekunakekeleni.

4. Isikhathi sokuvula nesokuvala side.
