Ukususela kwioyile negesi ukuya kwizityalo zonyango lwamanzi namanzi amdaka, iivalvu zidlala indima ebalulekileyo ekulawuleni ukuhamba kolwelo kumashishini. Olunye uhlobo lwevalvu oluye lwafumana ingqwalasela ebanzi kwiminyaka yakutshanje yivalvu yebhabhathane engaqhelekanga kathathu. Yenzelwe ukubonelela ngolawulo lokuhamba oluthembekileyo noluchanekileyo, le valve intsha inika iingenelo ezininzi kuneevalvu zebhabhathane zemveli. Kweli nqaku, siza kuhlola iimpawu, iingenelo kunye nokusetyenziswa kweevalvu zebhabhathane engaqhelekanga kathathu.

Ivalvu yebhabhathane engaqhelekanga kathathu ifumene igama layo ngenxa yoyilo lwayo olukhethekileyo oluquka izinto ezintathu ezingaqhelekanga. Ezi zinto ziphakathi komgama ophakathi komgca wesihlalo kunye nomgca ophakathi weshaft, umgca ophakathi webhore, kunye nomgca ophakathi wevalvu. Olu yilo luvumela idiski ukuba ijikeleze kakuhle kwaye itywine ngokuqinileyo kwisihlalo ukuze kungabikho kuvuza.

Ngokungafaniyo neevalvu zebhabhathane zemveli apho idiski ikhuhlana nesihlalo ngexesha lokusebenza, ivalvu yebhabhathane engaqhelekanga kathathu isusa ukungqubana ngokulungelelanisa idiski kunye nesihlalo kwii-engile ezahlukeneyo. Olu yilo lutsha lunciphisa ukuguguleka, lwandise ubomi bevalvu kwaye lunciphisa iindleko zokulungisa.

Eyona nzuzo iphambili yevalvu yebhabhathane engaqhelekanga kathathu kukukwazi kwayo ukuvala ngaphandle komoya. Ukuvalwa okuqinileyo okufunyenwe yile valve kuthintela nakuphi na ukuvuza okungafunekiyo, okubonelela ngokhuseleko oluphezulu kunye nokuthembeka. Olu phawu luyenza ilungele ukusetyenziswa apho ukuvuza kunokubangela iingozi zokusingqongileyo okanye umngcipheko ophezulu wokungasebenzi kakuhle kwezixhobo.

Enye inzuzo enkulu yeevalvu zebhabhathane ezi-eccentric ezintathu kukukwazi kwazo ukumelana nobushushu obuphezulu kunye noxinzelelo. Uyilo kunye nezixhobo zokwakha le valve ziyenza ifaneleke kumashishini aphatha ulwelo oluphezulu, njengokuvelisa umbane kunye namashishini e-petrochemical. Ulwakhiwo lwayo oluqinileyo luqinisekisa ukuba inokumelana noxinzelelo olukhulu, nto leyo eyenza ukuba ibe lukhetho oluhle kakhulu kwizicelo ezifuna amandla.

Ukongeza, ivalvu yebhabhathane engaqhelekanga kathathu inolawulo oluchanekileyo. Ngoyilo lwayo oluchanekileyo lwesihlalo kunye noyilo lwe-offset, ivalvu ibonelela ngolawulo olugqwesileyo lokuhamba kwamanzi, nokuba kumanzi aphantsi. Olu lawulo luchanekileyo lonyusa ukusebenza kakuhle kwenkqubo kwaye lunciphisa inkunkuma yamandla.

Ukuguquguquka kwevalvu yebhabhathane engaqhelekanga kathathu yenye inzuzo ekungafanele ingananzwa. Uyilo lwayo oluncinci nolukhaphukhaphu lwenza kube lula ukuyifaka kwiinkqubo ezahlukeneyo zemibhobho. Ngaphezu koko, ingasetyenziswa ngeendlela zesandla kunye nezenzekelayo kuxhomekeke kwiimfuno zesicelo.

Iivalvu zebhabhathane ezingaqhelekanga ezintathu zisetyenziswa kakhulu kwizityalo zonyango lweoyile negesi, iikhemikhali, ukuveliswa kombane, izityalo zonyango lwamanzi amdaka kunye nezinye izimboni. Isetyenziswa rhoqo kwimibhobho yegesi kunye nolwelo, ilawula ukuhamba kwamanzi kwaye yahlula iindawo zombhobho ukuze zigcinwe zisemgangathweni. Ukukwazi kwayo ukuphatha ulwelo olushushu kakhulu kuyenza ifaneleke kwizityalo zamandla ezishushu kunye nezicelo zokucocwa kwamanzi. Ukongeza, isetyenziswa kakhulu kwizityalo zonyango lwamanzi ukulawula ukuhamba kwamanzi ngexesha lokucocwa, ukubulala iintsholongwane kunye nokusasazwa kwamanzi.

Ukuqukumbela, ivalvu yebhabhathane engaqhelekanga kathathu yinkqubela phambili ebalulekileyo kwezobuchwepheshe kwicandelo lokulawula ukuhamba kwamanzi. Ngoyilo lwayo olukhethekileyo, iqinisekisa ukutywinwa okungenamoya, ukuchaneka kokulawula okugqwesileyo kunye nokukwazi ukujongana nobushushu obuphezulu kunye noxinzelelo. Ukuguquguquka kwayo kunye nokulula kokufakela kongeza ngakumbi ekukhangekeni kwayo. Iivalvu zebhabhathane ezi-triple offset zibonakala zisisixhobo esixabisekileyo njengoko amashishini eqhubeka nokufuna izisombululo zokulawula ukuhamba kwamanzi ezisebenzayo nezithembekileyo.
