I-valve icandelo lokulawula kwinkqubo yokuhambisa amanzi, enemisebenzi efana ne-truncation, ukulungiswa, ukuguqulwa, ukuthintela i-counter current, i-voltage elawulayo, i-diversion okanye i-overflow pressure.
Kukho iintlobo ezininzi zeevalvu, kwaye zinokwahlulwa zibe:
1. Iklasi yevalve yokuhamba: Isetyenziselwa ukusika okanye ukudibanisa ukuhamba okuphakathi.Kubandakanya ivalve yesango, ivalve enzulu, ivalve yediaphragm, ivalve yerotor, ivalve yebhola, ivalve yebhabhathane, njl.
2. Iklasi yevalve yokuhlelwa: Isetyenziselwa kakhulu ukulawula ukuhamba, uxinzelelo, njl njl.Kubandakanya iivalve ezilawulayo, iivalve zokuthoba, iivalve zokunciphisa uxinzelelo, njl.
3. Iklasi yevalve yokumisa umva: Isetyenziselwa ukuthintela i-medium ukusuka umva.Kubandakanya ivalve yokumisa yezakhiwo ezahlukeneyo.
4. Iklasi ye-Dives valve: isetyenziselwa ukusabalalisa, ukwahlula okanye ukuxuba okuphakathi.Kubandakanya iivalvu zokwabiwa kunye neevalvu ze-hydrophobic zezakhiwo ezahlukeneyo.
5. Iklasi yevalve yokhuseleko: isetyenziselwa ukhuseleko olungaphezulu koxinzelelo.Kubandakanya iintlobo ezahlukeneyo zeevalvu zokhuseleko.
Imathiriyeli yevalvu:
1. Iivalvu zezinto ezingezizo ezentsimbi ezifana neevalvu ze-ceramic, iivalvu zeglasi zokuqinisa ifayibha, iivalvu zeplastiki, ezinjengePVC kunye ne-ASB.
2. Iivalve zensimbi ezifana ne-copper alloy valve, i-valve ye-alloy ye-alloy, i-valve ye-alloy ye-lead, i-valve yensimbi ye-titanium, ivalve yensimbi ye-carbon, i-valve yensimbi ephantsi, i-valve yensimbi ephezulu, i-valve yensimbi.Iintsimbi ezininzi kunye neevalvu ezingaphezulu zisetyenziswa kwiindawo ezinokumelana neqabaka.
3. Ivalve yentsimbi yomzimba efana nevalve yelamba yelothe, ivelufa yeplastiki yokwambatha, ivelufa ye-enamel yentsimbi, kunye nevalve yefluorine yetetramel.Ngokuqhelekileyo isetyenziswa kubunjineli bamanzi amdaka amdaka.
Isango
I-valve yesango isetyenziswe njengomhla wokugqibela, kwaye yonke i-circulation ixhunyiwe ngokuthe ngqo xa ivuliwe ngokupheleleyo.I-valve yesango ngokuqhelekileyo ifanelekile kwiimeko zokusebenza ezingadingi ukuvula nokuvala, kwaye ugcine isango livulekile okanye livalwe ngokupheleleyo.Ayisebenziyo ukusetyenziswa njengolawulo okanye ukujula.Kwimithombo yeendaba ehamba ngesantya esiphezulu, isango linokubangela ukunyakaza kwesango phantsi kwendawo yokuvula indawo, kwaye ukunyakaza kunokonakalisa isitywina sesango kunye nesihlalo se-valve, kwaye ukuphosa kuya kubangela ukuba isango lihlanjululwe yi-medium.Ivalve yesango inokufaneleka kuxinzelelo lobushushu obuphantsi okanye ubushushu obuphezulu kunye noxinzelelo oluphezulu, kodwa ngokuqhelekileyo ayisetyenziselwa ukuthutha imibhobho efana nodaka kunye nezinye imidiya.
Izinto eziluncedo:① Ukuxhathisa ulwelo kuncinci;② i-torque efunekayo ukuvula nokuvala incinci;③ ingasetyenziswa kumbhobho weringi womnatha oqukuqela kumacala omabini, oko kukuthi, ukuhamba kwesiphakathi akukhawulelwanga;I-corrosion ye-medium incinci kune-valve e-truncated;⑤ Isakhiwo somzimba silula, kwaye inkqubo yokuvelisa ingcono;⑥ Ubude besakhiwo bufutshane.
Izinto ezingeloncedo:① Ubungakanani kunye nobude bokuvula bukhulu, kwaye indawo efuna ukufakwa nayo inkulu;② Ngethuba lokuvula kunye nenkqubo yokuvala, umntu wokutywinwa uhambelana nokungqubuzana, umonakalo mkhulu, kwaye kulula ukubangela i-abrasion kwiqondo lokushisa eliphezulu;③ Ivalve yesango ngokubanzi inezitywina ezimbini, eyongeza ubunzima obuthile ekusetyenzweni, ukucola nokulungisa;
Ivalve yokuvala
Ivalve ye-truncant isetyenziselwa ukunqumla ukuhamba okuphakathi.
