Uvavanyo Lokusebenza Kweevalvu: Ukuthelekiswa Kweevalvu Zebhabhathane, Iivalvu Zesango, kunye Neevalvu Zokujonga

Kwiinkqubo zemibhobho yemizi-mveliso, ukukhetha iivalvu kubalulekile. Iivalvu zebhabhathane, iivalvu zesango, kunye neevalvu zokujonga ziintlobo ezintathu eziqhelekileyo zeevalvu, nganye ineempawu zokusebenza ezizodwa kunye neemeko zokusetyenziswa. Ukuqinisekisa ukuthembeka nokusebenza kakuhle kwezi valves xa zisetyenziswa ngokwenene, uvavanyo lokusebenza kweevalvu lubaluleke kakhulu. Eli nqaku liza kuhlola iimpawu zokusebenza kwezi ntlobo zintathu zeevalvu kunye neendlela zazo zokuvavanya.

Ivalvu yebhabhathane

Iivalvu yebhabhathane ilawula ukuhamba kolwelo ngokujikelezisa idiski yayo. Ulwakhiwo lwayo olulula, ubungakanani obuncinci, kunye nobunzima obulula buyenza ifaneleke ukusetyenziswa koxinzelelo oluphantsi nokuhamba kwamanzi aphezulu. Uvavanyo lokusebenza lweevalvu zebhabhathane lubandakanya ikakhulu uvavanyo lokuvuza, uvavanyo lweempawu zokuhamba kwamanzi, kunye novavanyo lokumelana noxinzelelo.

1. Uvavanyo lokutywina: Ukusebenza kokuvala kwevalvu yebhabhathane kuchaphazela ngokuthe ngqo ukuvuza kolwelo. Ngexesha lovavanyo, uxinzelelo oluthile ludla ngokufakwa kwivalvu xa ivaliwe ukuze kubonwe ukuba kukho ukuvuza kolwelo na.
2. Uvavanyo lweempawu zokuhamba kwamanzi:Ngokulungisa i-engile yokuvula ivalvu, ubudlelwane phakathi kokuhamba komoya kunye noxinzelelo buyalinganiswa ukuze kuvavanywe igophe elibonisa ukuhamba komoya. Oku kubalulekile ekukhetheni ivalvu efanelekileyo.
3. Uvavanyo loxinzelelo: Ukumelana noxinzelelo yinto ebalulekileyo kuyilo lwevalvu kunye nokuveliswa kwayo. Ngexesha lovavanyo, ivalvu kufuneka imelane noxinzelelo oludlula uxinzelelo lwayo olulinganisiweyo ukuqinisekisa ukhuseleko phantsi kweemeko ezinzima.

Ivalvu yeSango

I Ivalvu yesango yivalvu elawula ukuhamba kolwelo ngokuhambisa idiski phezulu nasezantsi. Ifanelekile kwiindlela ezivulekileyo ngokupheleleyo okanye ezivaliweyo ngokupheleleyo. Uvavanyo lokusebenza kwevalvu yesango lubandakanya ikakhulu uvavanyo lokuvula nokuvala i-torque, uvavanyo lokutywina, kunye novavanyo lokumelana nokuguguleka.

1. Uvavanyo lokuvula nokuvala i-torque: Vavanya i-torque efunekayo ukuze ivalvu ivuleke kwaye ivalwe ukuqinisekisa ukuba kulula kwaye kukhuselekile ukusebenza.
2. Uvavanyo lokuxinana:Njengeevalvu zebhabhathane, uvavanyo lokuqina kweevalvu zesango nalo lubaluleke kakhulu. Ngokusebenzisa uxinzelelo, jonga ukuba akukho kuvuza na kwimeko yokuvalwa kwevalvu.
3. Uvavanyo lokuxhathisa ukunxitywa: Ngenxa yokungqubana phakathi kwediski yesango kunye nesihlalo sevalvu yevalvu yesango, uvavanyo lokumelana nokuguguleka lunokuvavanya uzinzo lokusebenza kwevalvu xa isetyenziswa ixesha elide.

Jonga iValve

IIvalvu yokujonga yivalvu evumela ulwelo ukuba luhambe kwicala elinye kuphela, ikakhulu ukuthintela ukubuya kwamanzi. Uvavanyo lokusebenza kwevalvu yokujonga luquka uvavanyo lokuhamba kwamanzi emva, uvavanyo lokuvuza, kunye novavanyo lokulahlekelwa nguxinzelelo.

1. Uvavanyo lokuhamba ngokubuyela umva: Ivavanya ukusebenza kwevalvu xa ulwelo luhamba ngendlela echaseneyo ukuqinisekisa ukuba lunokuthintela ngokufanelekileyo ukubuya kwamanzi.
2. Uvavanyo lokuxinana:Ngokufanayo, uvavanyo lokuqina kwevalvu yokujonga lubalulekile ukuqinisekisa ukuba akukho kuvuza kwenzekayo kwimeko evaliweyo.
3. Uvavanyo Lokulahlekelwa Nguxinzelelo:Ivavanya ukulahleka koxinzelelo okubangelwa yivalvu ngexesha lokuhamba kolwelo ukuqinisekisa ukusebenza kwayo kakuhle kwinkqubo.

Cisiphelo

Iivalvu zebhabhathane, iivalvu zesangokunyeiivalvu zokujonganganye ineempawu zokusebenza ezahlukeneyo kunye neemeko zokusetyenziswa. Uvavanyo lokusebenza kwevalvu lubalulekile xa kukhethwa ivalvu efanelekileyo. Uvavanyo lokuvala, iimpawu zokuhamba, ukumelana noxinzelelo, kunye nezinye izinto ziqinisekisa ukuthembeka nokusebenza kakuhle kwevalvu kwizicelo ezisebenzayo, ngaloo ndlela kuphucula ukhuseleko lokusebenza kunye nokusebenza kakuhle kwezoqoqosho kwenkqubo yonke yemibhobho.
