Ukusuka kwi-oyile negesi ukuya kumanzi kunye nezixhobo zokucocwa kwamanzi amdaka, iivalvu zidlala indima ephambili ekulawuleni ukuhamba kolwelo kumashishini.Olunye uhlobo lwesivalo esiye safumana ingqalelo enkulu kwiminyaka yakutshanje sisivalo sebhabhathane eccentric kathathu.Idizayinelwe ukubonelela ngolawulo oluthembekileyo noluchanekileyo lokuhamba, le valve ivelisa izinto ezininzi ezintle ngaphezu kweevalvu zebhabhathane zemveli.Kweli nqaku, siza kuphonononga iimpawu, izibonelelo kunye nokusetyenziswa kweevalvu zebhabhathane eziphindwe kathathu.

Ivalve yebhabhathane ene-eccentric eccentric ifumana igama layo kuyilo lwayo olulodwa olubandakanya izinto ezintathu ezizii-eccentricities.Ezi zithintelo ngumgama phakathi komgca ophakathi kwesihlalo kunye ne-shaft centerline, i-bore centerline, kunye ne-valve centerline.Olu luyilo luvumela idiski ukuba ijikeleze kakuhle kwaye itywine ngokuqinileyo ngokuchasene nesihlalo sokuvuza kwe-zero.

Ngokungafaniyo neevalvu zebhabhathane zemveli apho i-disc ikhuhla malunga nesitulo ngexesha lokusebenza, ivalve yebhabhathane ye-eccentric eccentric iphelisa ukukhuhlana ngokulungelelanisa idiski kunye nesihlalo kwii-engile ezahlukeneyo.Olu yilo luyilayo lunciphisa ukuguga, ukwandisa ubomi bevalvu kunye nokunciphisa iindleko zokulondoloza.

Olona ncedo luphambili lwevalve yebhabhathane ene-eccentric bubuchule bayo bokutywina be-hermetic.Isitywina esiqinileyo esiphunyezwe yile valve sithintela nakuphi na ukuvuza okungafunekiyo, ukubonelela ngezinga eliphezulu lokhuseleko kunye nokuthembeka.Olu phawu lwenza ukuba lulungele usetyenziso apho ukuvuza kunokubangela iingozi zokusingqongileyo okanye ukonyuka komngcipheko wokusilela kwesixhobo.

Enye inzuzo enkulu yeevalvu zebhabhathane eziphindwe kathathu kukukwazi ukumelana nobushushu obuphezulu kunye noxinzelelo.Uyilo kunye nezixhobo zokwakha le valve yenza ukuba ifaneleke kumashishini aphatha ulwelo oluphezulu lobushushu, njengokuvelisa amandla kunye namashishini epetrochemical.Ulwakhiwo lwayo olomeleleyo luqinisekisa ukuba luyakwazi ukujongana noxinzelelo olugqithisileyo lokwahluka, okwenza kube lukhetho oluhle kakhulu kwizicelo ezifunayo.

Ukongeza, ivalve yebhabhathane ye-eccentric eccentric inokuchaneka okugqwesileyo kokulawula.Nge-geometry yesitulo esichanekileyo kunye noyilo lwe-offset, ivalve ibonelela ngolawulo olubalaseleyo lokuhamba, nokuba kuphantsi.Olu lawulo luchanekileyo lwandisa inkqubo esebenzayo kwaye lunciphisa inkcitho yamandla.

Ukuguquguquka kwevalve yebhabhathane ene-triple eccentric yenye i-advanteji engafanele ihoywe.Uyilo lwayo oluhlangeneyo, olukhaphukhaphu lwenza ukuba kube lula ukuyifaka kwiinkqubo ezahlukeneyo zemibhobho.Ngaphaya koko, inokusebenza kwiimowudi zemanuwali kunye nezizenzekelayo ngokuxhomekeke kwiimfuno zesicelo.

Iivalvu zebhabhathane ezintathu ze-eccentric zisetyenziswa kakhulu kwi-oyile kunye negesi, iikhemikhali, ukuvelisa amandla, amanzi kunye nokucoca amanzi amdaka kunye namanye amashishini.Ngokuqhelekileyo isetyenziswe kwimibhobho yegesi kunye neyolwelo, ilawula ngokufanelekileyo ukuhamba kwaye ihlukanise amacandelo ombhobho ukwenzela ukulungiswa.Ukukwazi kwayo ukuphatha ulwelo oluphezulu lobushushu kuyenza ilungele iplanti yamandla obushushu kunye nezicelo zokucoca.Ukongezelela, isetyenziswa ngokubanzi kwizityalo zokunyanga amanzi ukulawula ukuhamba kwamanzi ngexesha lokuhlanjululwa, ukubulawa kweentsholongwane kunye nokusabalalisa.

Ukuqukumbela, ivalve yebhabhathane ephindwe kathathu yinkqubela phambili ebalulekileyo yetekhnoloji kwicandelo lolawulo lokuhamba.Ngoyilo lwayo olulodwa, iqinisekisa ukutywinwa kwe-hermetic, ukuchaneka okugqwesileyo kokulawula kunye nokukwazi ukuphatha amaqondo aphezulu kunye noxinzelelo.Ukuguquguquka kwayo kunye nokulula kofakelo kuyongeza ngakumbi kwisibheno sayo.Iivalvu zebhabhathane ezithathu zibonakalisa ukuba zisisixhobo esixabisekileyo njengoko amashishini eqhubeka efuna izisombululo ezisebenzayo nezithembekileyo zolawulo lokuqukuqela.
