IValve yeBhola yeTrunnion: Isisombululo esiNyuseko soLawulo lokuHamba kweShishini
Ehlabathini lolawulo lokuhamba kwemizi-mveliso, iivalve yebhola yetrunnionlicandelo eligqamayo ngokusebenza kwalo kunye nokuguquguquka.Ezi zivalo zidlala indima ebalulekileyo ekulawuleni ukuhamba kwamanzi kumacandelo ahlukeneyo, kuquka i-oyile negesi, iikhemikhali zepetroli, amayeza kunye nokuveliswa kwamandla.Ngoyilo lwazo olulodwa kunye nokusebenza okuphezulu, iivalve zebhola ze-trunnion ziye zaba yinxalenye yemisebenzi emininzi yoshishino.
Ke, yintoni kanye kanye elungisiweyoivalve yebhola?Ewe, ukuqonda ukubaluleka kwayo, masiqale ngesiseko se-anatomy yale valve.Iivalvu zebhola ze-trunnionziquka ibhola engqukuva enomngxuma embindini osebenza njengezibuko lepaseji yolwelo.Ibhola ibanjwe kwindawo yayo ngama-trunnions, azizikhondo ezimbini ezibekwe phezulu nasezantsi kwevalve.Ezi trunnions zibonelela ngokuzinza ngokugudileyo, ulawulo oluchanekileyo lokuvula nokuvalwa kwevalve.
Enye yeenzuzo eziphambili zeiivalvu zebhola ze-trunnionkukwazi kwabo ukuphatha uxinzelelo oluphezulu kunye nezicelo zobushushu obuphezulu.I-trunnion isasaza ngokufanelekileyo umthwalo kuwo wonke umzimba wevalve, ukuthintela uxinzelelo olugqithisileyo kwibhola kunye nendlela yokutywina.Oku kuqinisekisa ukusebenza okuthembekileyo kunye nokuvuza okungavuziyo naphantsi kweemeko ezinzima.Ukongezelela, idizayini ye-trunnion yenza ukuba i-valve ikwazi ukumelana nemikhosi eyenziwa ngumbane ohambayo, ukubonelela ukuchasana kwexesha elide.
Ukongeza,iivalvu zebhola ze-trunnionzibonelela ngezakhono zolawulo olubalaseleyo.Ngenxa yokwakhiwa kwebhola, ezi zivalo zibonelela ngendlela yokuhamba ngokuthe tye, ukunciphisa isiphithiphithi kunye nokuhla koxinzelelo.Olu phawu luluncedo ngakumbi apho kufuneka ukulawulwa kokuhamba okufanelekileyo, okufana nemibhobho, iindawo zokucokisa kunye nezityalo zokusetyenzwa kweekhemikhali.Uyilo lwe-trunnion lukwadala itywina eliqinileyo, elivumela ivalve ukuba ivale ngokufanelekileyo ukuhamba kwaye ithintele nakuphi na ukuvuza.
Olunye uphawu oluphawulekayo lwevalve yebhola yetrunnion kukuguquguquka kwayo ekuphatheni iintlobo ngeentlobo zolwelo, kubandakanywa izinto ezidlekayo, ezirhabaxa kunye ne-viscous.Izinto zokwakha zevalve, njengensimbi engenasici, i-carbon steel kunye ne-specialty alloys, ingenziwa ngokwezifiso ukuhlangabezana neemfuno ezithile zesicelo.Ukongeza,iivalvu zebhola ze-trunnionzifumaneka kwiindidi ezahlukeneyo zobukhulu kunye nokulinganiswa koxinzelelo, okwenza ukuba zilungele iinkqubo ezahlukeneyo zoshishino.
Ukusebenzisa ivalve yebhola yetrunnion kulula.Ngokujikeleza ibhola usebenzisa i-handle okanye i-actuator, ukuhamba kunokuvulwa ngokupheleleyo okanye kuvalwe ngokupheleleyo.Ivalve ikwavumela ukuvuleka kwenxalenye, ivumela ulawulo oluchanekileyo lokuhamba.Ukulula kokusebenza kunye nokuqina kunye nokuthembeka kwevalve kwenza kube lukhetho oludumileyo kumacandelo ahlukeneyo oshishino.
Lilonke, iivalvu zebhola ze-trunnion zibe sisisombululo sokuya kwisisombululo solawulo lokuhamba kweshishini.Uyilo lwayo olomeleleyo, ukumelana noxinzelelo oluphezulu, ulawulo olusebenzayo lokuhamba kunye nokuguquguquka kwenza kube yinto eyimfuneko kwizicelo ezahlukeneyo.Nokuba isetyenziswa kuthutho lweoyile negesi, ukuphatha imichiza, okanye ulawulo lweenkqubo zokuvelisa amandla,iivalvu zebhola ze-trunnionbabonakalise ukubaluleka kwabo ixesha nexesha kwakhona.Ngokusebenza kwazo okuphezulu kunye nokusebenza okuthembekileyo, ezi zivalo ziyaqhubeka nokwandisa ukusebenza kakuhle kunye nokuqinisekisa ukusebenza kakuhle kumashishini emhlabeni jikelele.
