Nguwuphi umahluko phakathi kweeVave zeBhola kunye neeVave zeSango

Iivalve zebhola kunye neevalvu zesangozineeyantlukwano ezibalulekileyo kulwakhiwo, umgaqo wokusebenza, iimpawu kunye nezihlandlo zokusetyenziswa.

Ulwakhiwo kunye noMgaqo wokuSebenza

Ivalve yeBhola: Lawula ukuhamba kolwelo ngokujikelezisa ibhola. Xa ibhola ijikeleza ukuze ihambelane ne-axis yombhobho, ulwelo lunokudlula; xa ibhola ijikeleza i-90 degrees, i-fluid ivaliwe. Isakhiwo se-valve yebhola sivumela ukuba isebenze phantsi koxinzelelo oluphezulu. Ibhola yevalve ilungisiwe, kwaye isiqu sevalve kunye ne-shaft yokuxhasa ibolisa inxalenye yoxinzelelo olusuka kwindawo ephakathi, inciphisa ukunxiba kwesihlalo sevalve, ngaloo ndlela yandisa ubomi benkonzo yevalve. ...

...Ivalve yesango: Lawula ukuhamba kolwelo ngokuphakamisa kunye nokuthoba ipleyiti yevalve. Xa ipleyiti yevalve ihambela phezulu, umjelo wolwelo uvulwa ngokupheleleyo; xa ipleyiti yevalve ihambela ezantsi ukuze ilingane nomzantsi wejelo lolwelo, ulwelo luvaleke ngokupheleleyo. Ipleyiti yevalve yevalve yesango ithwele uxinzelelo olukhulu olusuka kumbindi, ibangela ukuba ipleyiti yevalve icinezele kwisitulo sevalve esezantsi, inyusa ukukruxuka kunye nokuguga kwesitulo sevalve.

Izinto eziluncedo kunye nezingeloncedo kwiiValuvu zeBhola kunye neeVavu zeSango

Ivalve yeBhola:

...Izinto eziluncedo: isakhiwo esilula, ukutywinwa okulungileyo, ukuvulwa ngokukhawuleza kunye nokuvala, ukuchasana kwamanzi aphantsi, okufanelekileyo kwiinkqubo zombhobho ophezulu kunye nobubanzi obukhulu. Ifanelekile ngamaxesha apho ulwelo kufuneka lunqunyulwe ngokukhawuleza okanye ludityaniswe, lula ukusebenza, ubungakanani obuncinci, kunye nokugcinwa lula.

Izinto ezingeloncedo: ayifanelekanga ukulawula i-high-viscosity fluids kunye nokuhamba okuncinci. ...

Ivalo yeSango:

Izinto eziluncedo: ukutywinwa kakuhle, ukuchasana okuphantsi, isakhiwo esilula, esilungele ukusika okanye ukuvula ulwelo. Amandla okulawula ukuhamba okunamandla, alungele imibhobho yobubanzi obukhulu. ...

Izinto ezingeloncedo: Ukuvula okucothayo kunye nesantya sokuvala, asifanelekanga ukulawula i-high-viscosity fluids kunye nokuhamba okuncinci. ...

Umahluko kwimiba yesicelo

Ivalve yeBhola:esetyenziswa ngokubanzi kwiinkqubo zemibhobho kwimimandla yepetroleum, ishishini lemichiza, igesi yendalo, njl. ...

Ivalo yeSango:ngokuqhelekileyo ifumaneka kwiinkqubo zemibhobho kwimimandla yonikezelo lwamanzi, i-drainage, ukucocwa kogutyulo, njl., ukusika kunye nokuvula ulwelo.
