Iingenelo kunye nokungalungi kweeBall Valve kunye neeButterfly Valve kwiMarine

Kwiinkqubo zaselwandle, apho ukuthembeka kunye nokumelana nokugqwala kubaluleke kakhulu, ukukhethwa kweevalvu kunokwenza umahluko omkhulu ekusebenzeni nasekugcinweni. Iindidi ezimbini zevalvu eziqhelekileyo ezisetyenziswa kwiinqanawa zeziiivalvu zebholakwayeiivalvu zebhabhathaneZombini zilawula ukuhamba kolwelo ngokufanelekileyo, kodwa zahlukile kwisakhiwo, ukusebenza, kunye nokusetyenziswa okufanelekileyo. Makhe sijonge ngokusondeleyo iingenelo kunye nokungalungi kwazo kwindalo esingqongileyo yolwandle.

Iivalvu zeBhola: Ukutywina okuQinileyo kunye nokusebenza okuthembekileyo

Iivalvu zebhola zisebenzisa idiski engqukuva enomngxuma ophakathi ukulawula ukuhamba kwamanzi. Xa isiphatho sijikwe ngama-90 degrees, ivalvu ivuleka ngokupheleleyo okanye ivale.

Iingenelo zeevalvu zebhola ekusetyenzisweni kolwandle

• ①Ukusebenza kakuhle kokutywina:Iivalvu zebhola zivala ngokuqinileyo, zithintela ukuvuza nokuba kuphantsi koxinzelelo oluphezulu. Oku kubalulekile kwimigca yamafutha aselwandle kunye neenkqubo ze-bilge.

• ②Ukuqina:Zenziwe ngezinto ezimelana nokugqwala ezifana nebronze okanye intsimbi engatyiwayo, iivalvu zebhola ziyamelana nokuchatshazelwa ngamanzi olwandle kunye noxinzelelo oluphezulu.

• ③Ukusebenza okulula:Isibambo esilula sokujika ikota senza ukuba zikhawuleze kwaye kube lula ukuzisebenzisa, nokuba zikwiindawo ezixineneyo.

• ④Ulondolozo oluphantsi:Uyilo lwazo oluncinci luthetha ukuba iindawo ezigugileyo azinakwa, nto leyo enciphisa iimfuno zokugcinwa kweenqanawa.

Iingxaki zeevalvu zebhola

• ①Ixabiso eliphezulu:Iivalvu zebhola zihlala zibiza kakhulu kuneevalvu zebhabhathane ezinobukhulu obufanayo.

• ②Uyilo olunzima:Zinokuba zikhulu ngakumbi, nto leyo esenokungalungelani neenkqubo ezinesithuba esilinganiselweyo sokufakela.

• ③Ubuchule obuncinci bokubhoboza:Iivalvu zebhola azilungele ukulawulwa kokuhamba kwamanzi; zisebenza kakuhle kwiindawo ezivulekileyo okanye ezivaliweyo.

Ngenxa yezi mpawu, iivalvu zebhola zikhethwa kakhulu kwiinkqubo zepetroli, iintambo zomoya ezixinzelelweyo, kunye neesekethe ze-hydraulic apho ukutywina kunye nokuqina kwezixhobo zezona zinto ziphambili.

Iivalvu zebhabhathane: Zilula kwaye zigcina indawo

Iivalvu zebhabhathane zisebenzisa idiski ejikelezayo efakwe kwintonga ukulawula ukuhamba kwamanzi. Xa zijikwa, idiski ivula okanye ivale indlela yokuhamba. Zisetyenziswa kakhulu kumanzi okupholisa, i-ballast, kunye neenkqubo zomoya ezikwiinqanawa.

Iingenelo zeeValve zeButterfly ekusetyenzisweni kolwandle

• ①Incinci kwaye ilula:Iprofayili yazo encinci kunye nobunzima bayo obulula buyenza ifaneleke kwiindawo ezixineneyo kumagumbi eenjini zaselwandle.

• ②Ixabiso elifanelekileyo:Iivalvu zebhabhathane zihlala zifikeleleka lula, ingakumbi kwiidayamitha ezinkulu.

• ③Ukusebenza ngokukhawuleza:Njengeevalvu zebhola, zifuna ukujika kwekota kuphela ukuze zivuleke okanye zivale.

• ④Ilungele ukulawula ukuhamba kwamanzi:Zingasetyenziselwa ukulawula ukuhamba kolwelo ngokuchanekileyo ngakumbi kuneevalvu zebhola.

Iingxaki zeeValve zeButterfly

• ①Ukuvalwa okuncinci:Idiski ihlala kwindlela yokuhamba, ngoko ke ayinakutywinwa ngokupheleleyo njengeevalvu zebhola.

• ②Ukumelana nokuhamba kwamanzi:Uyilo oluthintelweyo kancinci lunokubangela ukuhla okuncinci koxinzelelo.

• ③Ubuthathaka bokunxiba:Izitulo zerabha okanye ze-elastomer zinokuguga ngokuhamba kwexesha kwiindawo ezimanzi olwandle, nto leyo edinga ukuvavanywa rhoqo.

Nangona ezi ngxaki zingekho, iivalvu zebhabhathane zisathandwa kakhulu kwiipayipi ezinkulu kunye neenkqubo eziphantsi koxinzelelo apho indawo, iindleko, kunye nobunzima zizinto ezibalulekileyo ekufuneka ziqwalaselwe.
