Iibhokisi zegiya zevalvu zebhola zizinto ezibalulekileyo kwizicelo ezininzi zemizi-mveliso, zibonelela ngezibonelelo eziyimfuneko zoomatshini ukuze kusebenze iivalvu zebhola ngokufanelekileyo.Ezi bhokisi zegiya ziyilelwe ukuphatha itorque ephezulu efunekayo ukujika iivalve zebhola, ezihlala zisetyenziselwa ukulawula ukuhamba kolwelo okanye iigesi kwinkqubo.Kweli nqaku, siza kuphonononga umsebenzi kunye nokubaluleka kweebhokisi zegiya zevalvu kumashishini ahlukeneyo.
Iibhokisi zegiya zevalvu yebhola ziqhele ukusetyenziswa kumashishini afana neoyile negesi, i-petrochemical, unyango lwamanzi kunye nokuveliswa kwamandla.Kula mashishini, iivalvu zebhola zisetyenziselwa ukulawula ukuhamba kwamanzi kwimibhobho, iitanki, kunye nezinye izixhobo zokusebenza.Iibhokisi zegiya zevalvu yebhola zibalulekile ekuqinisekiseni ukuba ivalve isebenza ngokukhuselekileyo nangokuthembekileyo naphantsi kweemeko zokusebenza ezinzima.
Omnye wemisebenzi ephambili yebhokisi yegiya yevalve kukubonelela ngoncedo lomatshini olufunekayo ukujika ivalve yebhola.Iivalvu zebhola ziyilwe ngento evalayo engqukuva esebenza ngokuqhelekileyo ngentshukumo yekota.Oku kufuna i-torque eninzi, ngakumbi kwiivalve ezinkulu okanye eziphantsi koxinzelelo oluphezulu okanye ubushushu.Ibhokisi yegiya inoxanduva lokukhulisa amandla okufaka isandla kwivili lesandla okanye kwi-actuator ukuze ivalve isebenze lula.
Ukongeza ekuboneleleni ngezibonelelo zoomatshini, iibhokisi zegiya zevalvu zikwabonelela ngenqanaba lolawulo kunye nokuchaneka ekusebenzeni kwevalvu.Iibhokisi zegiya ezininzi zixhotyiswe ngeempawu ezinjengokumisa okuhlengahlengiswayo kunye nezalathisi zendawo ezivumela abaqhubi ukuba babeke ngokuchanekileyo ivalve kunye nokulawula ukuhamba kolwelo lwenkqubo.Eli nqanaba lolawulo libalulekile kumashishini afuna ukulawulwa kokuhamba okuchanekileyo ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle kuyo yonke inkqubo.
Omnye umba obalulekileyo weebhokisi zegiya zevalve kubuchule bazo bokumelana neemeko zokusebenza ezinzima.Kumashishini afana neoli kunye negesi, i-petrochemicals kunye nokuveliswa kwamandla, iivalve zihlala zibonakaliswe kumaqondo okushisa aphezulu, uxinzelelo, iikhemikhali ezinobungozi kunye nezinye iindawo ezinzima.Iibhokisi zegiya zevalvu yebhola ziyilelwe ukuba zimelane nezi meko, zihlala zinolwakhiwo olurhabaxa kunye nezixhobo ezinokumelana namaqondo obushushu agqithisileyo, umhlwa kunye nokunxitywa koomatshini.
Kukwafanelekile ukukhankanya ukuba iibhokisi zegiya zevalvu ezininzi ziyilelwe ukuba zibe lula ukuzigcina nokuzilungisa.Oku kubalulekile kumashishini apho ixesha lokuphumla libiza kwaye nakuphi na ukusilela kwezixhobo kunokuba nemiphumo ekude.Uyilo lwemodyuli yebhokisi yegiya kunye namalungu atshintshekayo ngokulula enza kube lula kubasebenzi bolondolozo ukuba bahlole, balungise kwaye batshintshe iinxalenye njengoko kuyimfuneko, ukuqinisekisa ukuba isivalo sihlala sisebenza kwaye sithembekile.
Isishwankathelo, iibhokisi zegiya zevalve zebhola zidlala indima ebalulekileyo ekusebenzeni kweevalvu zebhola kwizicelo ezahlukeneyo zemizi-mveliso.Banikezela ngezibonelelo eziyimfuneko zomatshini, ukulawula kunye nokuthembeka ukuqinisekisa ukuba iivalve zebhola zinokusebenza ngokukhuselekileyo nangempumelelo phantsi kweemeko ezifunayo.Ngolwakhiwo lwazo olurhabaxa, amandla okulawula achanekileyo kunye nokulula ukulungiswa, iibhokisi zegiya zevalve zebhola zizinto ezibalulekileyo kumashishini apho ukulawulwa kwamanzi okanye ukuhamba kwegesi kubaluleke kakhulu.
