UVavanyo lokuSebenza kweValve: Uthelekiso lweeValufa zeButterfly, iiValuvu zeSango, kunye neeValufa zokuHlola

Kwiinkqubo zemibhobho yoshishino, ukhetho lwevalvu lubalulekile. Iivalve zebhabhathane, iivalvu zesango, kunye neevalve zokujonga zintathu iindidi zevalvu eziqhelekileyo, nganye ineempawu zokusebenza ezizodwa kunye neemeko zesicelo. Ukuqinisekisa ukuthembeka kunye nokusebenza kakuhle kwezi valve ekusetyenzisweni kokwenene, ukuhlolwa kokusebenza kwevalve kubaluleke kakhulu. Eli nqaku liza kuphonononga iimpawu zokusebenza kwezi ntlobo zintathu zevalve kunye neendlela zabo zokuvavanya.

Ivalve yebhabhathane

IIvalve yebhabhathane ilawula ukuhamba kolwelo ngokujikelezisa idiski yayo. Isakhiwo sayo esilula, ubungakanani be-compact, kunye nobunzima obulula buyenza ilungele ukuhamba okuphezulu, izicelo eziphantsi koxinzelelo. Uvavanyo lwentsebenzo yeevalvu zebhabhathane ngokuyintloko lubandakanya uvavanyo lokuvuza, uvavanyo lweempawu zokuqukuqela, kunye novavanyo lokumelana noxinzelelo.

1. Uvavanyo lokutywina: Ukusebenza kokutywinwa kwevalve yebhabhathane kuchaphazela ngokuthe ngqo ukuvuza kolwelo. Ngexesha lokuvavanya, uxinzelelo oluthile ludla ngokusetyenziswa kwi-valve kwimeko evaliweyo ukujonga ukuba kukho ukuvuza kwamanzi.
2. UVavanyo lweempawu zokuHamba:Ngokulungelelanisa i-angle yokuvula i-valve, ubudlelwane phakathi kokuhamba kunye noxinzelelo kulinganiswa ukuvavanya i-curve ye-curve yeempawu. Oku kubalulekile ekukhetheni ivalve efanelekileyo.
3. Uvavanyo loxinzelelo: Ukumelana noxinzelelo yinto ebalulekileyo kuyilo lwevalvu kunye nokuveliswa. Ngethuba lolu vavanyo, i-valve kufuneka imelane noxinzelelo oludlula uxinzelelo olulinganisiweyo ukuze kuqinisekiswe ukhuseleko phantsi kweemeko ezinzima.

Ivalve yeSango

I ivelufa yesango sisivalo esilawula ukuhamba kolwelo ngokuhambisa idiskhi inyuke ihle. Ifanelekile kwizicelo ezivuliwe ngokupheleleyo okanye ezivaliwe ngokupheleleyo. Uvavanyo lokusebenza kwevalvu yesango ngokuyintloko kubandakanya ukuvula kunye nokuvala uvavanyo lwetorque, uvavanyo lokutywina, kunye novavanyo lokumelana nokunxiba.

1. Ukuvula kunye nokuvala uvavanyo lwetorque: Vavanya i-torque efunekayo ukuze i-valve ivule kwaye ivale ukuqinisekisa ukukhululeka kunye nokhuseleko lokusebenza.
2. Uvavanyo lokuqina:Ngokufanayo neevalvu zebhabhathane, ukuxinana kweevalvu zesango nako kubaluleke kakhulu. Ngokufaka uxinzelelo, khangela ukuba kukho ukuvuza kwimeko evaliweyo yevalve.
3. Uvavanyo lokumelana nokunxiba: Ngenxa yokungqubuzana phakathi kwediski yesango kunye nesihlalo se-valve ye-valve yesango, uvavanyo lokumelana nokugqoka lunokuvavanya ukuqina kokusebenza kwevalve ekusebenziseni ixesha elide.

Jonga iValve

Iivelufa yokukhangela ivalve evumela ulwelo ukuba luhambe kwicala elinye kuphela, ngokuyintloko ukuthintela ukubuya umva. Iimvavanyo zokusebenza zevalve zibandakanya uvavanyo lokubuyela umva, uvavanyo lokuvuza, kunye novavanyo lokulahleka koxinzelelo.

1. UVavanyo lokuHamba okuBuyiswa: Ivavanya ukusebenza kwevalve xa ulwelo luqukuqela kwicala elingasemva ukuqinisekisa ukuba inokuthintela ngokufanelekileyo ukubuya umva.
2. Uvavanyo lokuqina:Ngokufanayo, uvavanyo lwe-tightness ye-valve yokutshekisha kwakhona kubalulekile ukuqinisekisa ukuba akukho kuvuza okwenzekayo kwimeko evaliweyo.
3. Uvavanyo lweLahleko loxinzelelo:Ukuvavanya ilahleko yoxinzelelo olubangelwa yi-valve ngexesha lokuhamba kwamanzi ukuze kuqinisekiswe ukusebenza kwayo kwinkqubo.

Cukuqukwa

Iivalve zebhabhathane, iivalve zesango, kwayekhangela iivalvenganye ineempawu zokusebenza ezahlukeneyo kunye neemeko zesicelo. Uvavanyo lokusebenza kwevalve lubalulekile xa ukhetha ivalve elungileyo. Uvavanyo lokutywinwa, iimpawu zokuhamba, ukumelana noxinzelelo, kunye nezinye iinkalo ziqinisekisa ukuthembeka kwe-valve kunye nokusebenza kakuhle kwizicelo eziphathekayo, ngaloo ndlela kuphuculwe ukhuseleko lokusebenza kunye nokusebenza kakuhle kwezoqoqosho kuyo yonke inkqubo yepayipi.
