Xa kufikwa kwiivalvu zoshishino, iivalvu zebhola ezifakwa phezulu ziyinxalenye ebalulekileyo kwizicelo ezininzi. Olu hlobo lwevalvu lwaziwa ngokuthembeka kwalo, ukuqina kwalo, kunye nokuguquguquka kwalo, nto leyo eyenza ukuba lube lukhetho oludumileyo kwiindidi ezahlukeneyo zemizi-mveliso. Kule khokelo ibanzi, siza kujonga ngokunzulu iimpawu eziphambili, iingenelo, kunye nokusetyenziswa kweevalvu zebhola ezifumaneka phezulu.
Iimpawu eziphambili zeevalvu zebhola ezifakwe phezulu
Iivalvu zebhola zokufikelela phezulu zenzelwe indawo yokungena efakwe phezulu ukuze kube lula ukufikelela kwizinto zangaphakathi. Olu phawu luvumela ukugcinwa, ukulungiswa kunye nokutshintshwa kwezixhobo ngokukhawuleza nangokulula ngaphandle kokususa ivalvu kumbhobho. Ukongeza, uyilo lokungena phezulu lunciphisa umngcipheko wokuvuza kwaye luqinisekisa ukuvalwa okuqinileyo, okwenza ukuba ilungele ukusetyenziswa koxinzelelo oluphezulu kunye nobushushu obuphezulu.
Olunye uphawu oluphawulekayo lwevalvu yebhola yokufikelela ephezulu luyilo lwayo olunezibuko ezipheleleyo, oluvumela ukuhamba okungenamkhawulo kunye nokwehla okuncinci koxinzelelo. Olu phawu loyilo lubalulekile kwizicelo ezifuna ukuhamba kolwelo ngokufanelekileyo kunye nokulahleka okuncinci kwamandla.
Iingenelo zeevalvu zebhola ezifakwe phezulu
Enye yezona nzuzo ziphambili zeevalvu zebhola ezifikelela phezulu kukwakhiwa kwazo okuqinileyo, okuqhele ukwenziwa ngezinto ezikumgangatho ophezulu ezifana nentsimbi engagqwaliyo, intsimbi yekhabhoni, okanye intsimbi ye-alloy. Olu lwakhiwo luqinisekisa ukuhlala ixesha elide kwevalvu kwaye lunciphisa isidingo sokugcinwa nokutshintshwa rhoqo, nokuba phantsi kweemeko ezinzima zokusebenza.
Ukongeza, iivalvu zebhola ezifakwe phezulu zisebenza kakuhle kakhulu ekutywineni ngenxa yoyilo lwazo lwebhola edadayo kunye nezixhobo zokutywina ezinokuthenjwa. Olu phawu lwenza ivalvu ifaneleke ukusetyenziswa kunye nolwelo olwahlukeneyo, kuquka i-corrosive kunye ne-abrasive media, ngaphandle kokuchaphazela ukusebenza kwayo.
Ukusetyenziswa kweevalvu zebhola ezifakwe phezulu
Iivalvu zebhola ezifakwa phezulu zisetyenziswa kumashishini ahlukeneyo, kuquka ioyile negesi, iikhemikhali zepetroli, ukucutshungulwa kweekhemikhali, ukuveliswa kombane kunye nokucocwa kwamanzi. Ukuguquguquka kwayo kunye nokukwazi kwayo ukumelana noxinzelelo oluphezulu kunye namaqondo obushushu kwenza ukuba ifaneleke kwizicelo ezibalulekileyo ezifana nokuvala, ukwahlulahlula kunye nokulawula ukuhamba kolwelo.
Kwishishini leoyile negesi, iivalvu zebhola ezifakwe phezulu zisetyenziswa kakhulu kwiinkqubo zemibhobho, iintloko zemithombo kunye nezixhobo zemveliso. Ukukwazi kwazo ukumelana neemeko ezinzima zokusebenza kunye nokubonelela ngokuvalwa okuthembekileyo kuzenza zibe yinxalenye ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokusebenza kakuhle kwemisebenzi yeoyile negesi.
Kwimizi-mveliso yokucubungula iikhemikhali kunye neekhemikhali zepetroli, iivalvu zebhola ezifakwe phezulu zisetyenziselwa ukuphatha ulwelo olurhabaxa nolurhabaxa ngenxa yokwakhiwa kwazo okuqinileyo kunye neempawu ezibalaseleyo zokutywina. Ezi valve zidlala indima ebalulekileyo ekulawuleni ukuhamba kweekhemikhali kunye nokuqinisekisa ukuthembeka kweenkqubo zenkqubo.
Ukuqukumbela, ivalvu yebhola yokufikelela ephezulu yinxalenye eguquguqukayo nethembekileyo enika iingenelo ezininzi kwiintlobo ngeentlobo zezicelo zoshishino. Uyilo lwayo oluphezulu, ulwakhiwo oluqinileyo kunye neempawu ezibalaseleyo zokutywina zenza ukuba ibe lolona khetho luphambili kwiizicelo ezibalulekileyo zolawulo lolwelo. Nokuba kumashishini eoyile negesi, ukucubungula iikhemikhali okanye ukuvelisa umbane, iivalvu zebhola ezifakwe phezulu bezisoloko zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko, ukusebenza kakuhle kunye nokuthembeka kweenkqubo zoshishino.
