Izinto Ezicatshangelwayo Ngesiqu Se-Valve Ezivela Ekukhiqizeni Kwangempela Nokusetshenziswa Kwensimu

Ukubuka Konke Kwesiqu Sevalvu

Ekukhiqizweni kwama-valve kanye nezimo zangempela zesevisi, Isiqu seValvu Akuyona ingxenye evame ukuthola ukunakwa okukhulu ekuqaleni. Kodwa-ke, lapho kuvela izinkinga ezifana ne-torque ephezulu yokusebenza, ukunyakaza okungazinzile, noma ukuvuza kokupakisha kusenesikhathi, uphenyo luvame ukuholela emuva ku-Valve Stem.

Ngokombono osebenzayo, i-Valve Stem inesibopho sokudlulisa ukunyakaza kusuka esondweni lesandla noma i-actuator kuya entweni yokuvala. Lokhu kuzwakala kulula, kodwa empeleni i-Valve Stem isebenza ngaphansi kwemithwalo ehlanganisiwe. Ibona ukugoba ngesikhathi sokusebenza, amandla e-axial avela ekucindezelweni, kanye nokucindezeleka okuphindaphindiwe okuvela ekuvulekeni nasekuvaleni njalo.

Ezisetshenzisweni ezizenzakalelayo noma ezisebenza ngomjikelezo ophezulu, lezi zici ziba sobala kakhulu. I-Valve Stem engaqondile ngokwanele ingadala ukumelana okungalingani ngesikhathi sokusebenza. Isimo esibi sobuso endaweni yokuvala sivame ukusheshisa ukuguguleka kokupakisha. Kwezinye izimo, ukuphambuka okuncane kakhulu kobukhulu ku-Valve Stem kwanele ukuthinta ukunemba kokubeka, ikakhulukazi lapho kuhileleke ama-actuator omoya noma kagesi.

Ukukhethwa Kwezinto Ezibalulekile

Ukukhethwa kwezinto kungenye indawo ethinta ngqo ukusebenza kwe-Valve Stem. Ngensizakalo ejwayelekile, imiklamo ye-Valve Stem yensimbi yekhabhoni ivame ukusetshenziswa futhi isebenza kahle. Ezindaweni ezigqwalisayo noma ezishisa kakhulu, izinketho zensimbi engagqwali njenge-martensitic noma amamaki aqiniswe yimvula zivame ukuthandwa. Ekusetshenzisweni kukawoyela negesi, ukukhethwa kwezinto ze-Valve Stem kudinga futhi ukucabangela ukumelana nokugqwala nokuqhekeka kokucindezeleka, hhayi nje amandla.

Ngokombono wokukhiqiza, i-Valve Stem akuyona ingxenye elula eguqulwayo. Ukuphela kwendawo yokupakisha, ukuguquka kwezinyathelo, kanye nokwelashwa komphetho konke kuthonya indlela uhlelo lokuvala oluziphatha ngayo ngokuhamba kwesikhathi. Kuma-valve amakhulu noma imiklamo ye-long-stroke, ukugcina ukugxila kanye nokuqondile kubude obugcwele be-Valve Stem kubaluleke kakhulu. Uma lokhu kungalawulwa ngesikhathi sokugaya, ukuhlanganiswa kanye nokusebenza kwesikhathi eside kungathinteka kokubili.

Njengoba ama-actuator esetshenziswa kabanzi, ukwakheka kwe-Valve Stem kumele futhi kubheke amazinga aphezulu omjikelezo kanye nokumelana nokukhathala. Izici ezifana nesakhiwo sokulwa nokuqhuma, amandla anele ehlombe, kanye nokuxhumeka kwe-actuator okuthembekile manje sekuyizinto ezijwayelekile zokucatshangelwa. Le mininingwane ivame ukunganakwa, kodwa ithinta ngqo impilo yesevisi kanye nokuphepha kokusebenza.

Isiphetho

Ngokusekelwe kumpendulo yasensimini, i-Valve Stem eklanywe kahle futhi eyenziwe kahle isiza ukunciphisa i-torque yokusebenza, ithuthukisa ukuzinza kokuvala, futhi yehlisa imvamisa yokugcinwa. Nakuba i-Valve Stem ingaxhumani ngqo nemidiya yenqubo, inomthelela oqondile ekutheni i-valve isebenza ngokwethembeka kangakanani ngokuhamba kwesikhathi.
