Ivalvu yebhabhathane

Ivalvu yebhabhathane ikwicandelo levalvu yekota. Iivalvu zekota ziquka iintlobo zeevalvu ezinokuvulwa okanye zivaliwe ngokujika isiqu kwikota.iivalvu zebhabhathane, kukho idiski enamathele kwisiqu. Xa intonga ijikeleza, ijikeleza idiski ngekota, nto leyo ebangela ukuba idiski iwele ngokuthe nkqo kulwelo ize iyeke ukuhamba. Ukubuyisela ukuhamba, isiqu sijikeleza idiski sibuyele kwindawo yaso yokuqala, kude nokuhamba.

Iivalvu zeButterfly zithandwa kakhulu kuba kulula ukuzifaka, azibizi mali ingako, kwaye ziyafumaneka phantse kuzo zonke iisayizi. Ezi zihlala zisetyenziselwa iinkonzo zolawulo kunye neenjongo zokutshintsha.

Ukusetyenziswa kwevalvu yebhabhathane

Iivalvu zebhabhathane zibalulekile kwiinkqubo nakwimisebenzi kwimizi-mveliso eyahlukeneyo. Oku kungenxa yobukhulu bazo kunye nokukwazi kwazo ukulawula ukuhamba kolwelo, igesi kunye nodaka. Iivalvu zebhabhathane azikwazi nje kuphela ukumisa okanye ukuqala ukuhamba, kodwa zikwanokunciphisa okanye zinciphise ukuhamba njengoko kufuneka xa zivuliwe kancinci.

Abathengi abavela kumashishini amaninzi bathenga iivalvu zeebhabhathane, kuquka ezo zikwicandelo lokulungisa ukutya (ulwelo), izityalo zamanzi, ukunkcenkceshela, ukwenziwa kwemibhobho, ukwenziwa kwemizi-mveliso, iinkqubo zokufudumeza kunye nokuthuthwa kweekhemikhali.

Nangona iivalvu zebhabhathane zinezicelo ezininzi ezahlukeneyo, ezinye zezicelo ezithile ziquka i-vacuum, ukubuyisa ioyile, inkonzo yomoya ocinezelweyo, ukupholisa umoya namanzi, i-HVAC, inkonzo yodaka, inkonzo yamanzi anoxinzelelo oluphezulu, inkonzo yamanzi anobushushu obuphezulu, inkonzo yomphunga kunye nokukhusela umlilo.

Ngenxa yokwahluka koyilo kunye nezixhobo, iivalvu zebhabhathane zineendlela ezahlukeneyo zokusetyenziswa. Ezi zinokufakwa kuyo nayiphi na ipayipi, ukusuka kumanzi acocekileyo ukuya kulwelo lokugaya okanye ulwelo olumdaka. Ezi zihlala zisetyenziswa kwizicelo zodaka okanye udaka, iinkonzo zokucoca i-vacuum, iinkonzo zomphunga, ukusetyenziswa kwamanzi okupholisa, umoya, okanye igesi.

Iingenelo kunye nokungalungi kwevalvu yebhabhathane

Iivalvu zebhabhathanezibonelela abasebenzisi ngeenzuzo ezininzi. Okokuqala, zinoyilo oluncinci. Ngenxa yolu yilo luncinci, azifuni ndawo yokusebenza ininzi kunezinye iivalvu ezininzi. Okwesibini, iindleko zokugcina iivalvu zebhabhathane ziphantsi kakhulu. Okwesibini, zibonelela ngokuxinana kwezithuthi ezisemgangathweni ophezulu. Kwakhona, azivuzi, kodwa zinokuvulwa lula xa kufuneka. Enye inzuzo yevalvu yebhabhathane lixabiso layo eliphantsi.

Iingenelo zevalvu yebhabhathane

1. Ngenxa yobukhulu bazo obuncinci kunye noyilo oluncinci, iindleko zokufakela ziphantsi kakhulu.

2. Ezi valve zithatha indawo encinci kakhulu xa kuthelekiswa nezinye valve.

3. Ukusebenza ngokuzenzekelayo kwenza kube lula kwaye kube ngcono kunezinye iivalvu.

4. Ngenxa yoyilo lweediski ezininzi kunye neendawo ezimbalwa ezihambayo, ayifuni ukugcinwa kakhulu, nto leyo enciphisa kakhulu ukuguquguquka kwemozulu.

5. Izixhobo ezahlukeneyo zesihlalo zenza kube lula ukuzisebenzisa kuzo zonke iintlobo zeendawo, kwanakwiindawo ezirhabaxa.

6. Iivalvu zebhabhathane azifuni zinto zininzi, kulula ukuziyila nokuyila, kwaye ngokubanzi zibiza kancinci kunezinye iintlobo zeevalvu.

7. Iivalvu zebhabhathane zingasetyenziswa kwiindlela ezahlukeneyo zokusebenza, kuquka ukufakelwa komhlaba.

Iingxaki zevalvu yebhabhathane

Enyanisweni, iingxaki zeevalvu zeebhabhathane zingaphezulu kuneenzuzo. Kodwa ngaphambi kokuba usebenzise ezi valve, kusekho izinto ekufuneka uzikhumbule.

1. Nokuba ivuliwe ngokupheleleyo, indawo encinci yediski iya kuthintela ukuhamba kwezinto. Oku kunokuchaphazela intshukumo yendawo yediski kunye neswitshi yoxinzelelo kumbhobho.

2. Umsebenzi wokutywina awulunganga njengezinye iivalvu.

3. Ukuqhobosha kusebenza kuphela kwinkonzo yoxinzelelo oluphantsi.

4. Ivalvu yebhabhathane isoloko inomngcipheko wokuthintela ukuhamba okanye ukugabha kwesisu.

Ulwakhiwo lwevalvu yebhabhathane

Iivalvu zebhabhathane zineempawu eziphambili ezininzi. Ezi ziquka umzimba, idiski, isiqu, kunye nesihlalo. Zikwanayo ne-actuator, efana ne-lever. Umqhubi angajikelezisa i-actuator yevalvu ukutshintsha indawo yediski.

Umzimba wevalvu ufakwe phakathi kweeflange ezimbini zepayipi. Eyona ixhaphakileyo kuzo zonke iintlobo zoyilo lomzimba ziilugs kunye neediski.

Umgaqo wokusebenza wediski yevalvu ufana nesango elikwivalvu yesango, iplagi kwivalvu yeplagi, ibhola elikwivalvuivalvu yebhola, njl. Xa ijikeleziswa ngama-90 ° ukuze ihambe ngokuhambelana nolwelo, idiski ikwindawo evulekileyo. Kule ndawo, idiski iya kuvumela lonke ulwelo ukuba ludlule. Xa idiski ijikeleza kwakhona, idiski ingena kwindawo evaliweyo kwaye ithintele ukuhamba kolwelo. Ngokuxhomekeke kwindlela idiski ebekwe ngayo kunye noyilo, umenzi unokulawula i-torque yokusebenza, isitywino kunye/okanye ukuhamba kwayo.

Isiqu sevalvu singumngxuma. Sinokuba sisiqwenga esinye okanye ezibini. Ukuba sesokugqibela, sibizwa ngokuba sisiqu esiqhekekileyo.

Isihlalo siqhagamshelwe emzimbeni wesithuthi ngokusebenzisa iindlela zokucinezela, zokubopha okanye zokutshixa. Umenzi udla ngokwenza isihlalo sevalvu ngepolymer okanye i-elastomer. Injongo yesihlalo sevalvu kukubonelela ngomsebenzi wokuvala ivalvu. Yingakho amandla ajikelezayo afunekayo ekuvaleni ivalvu yebhabhathane ebizwa ngokuba yi-"seat torque", ngelixa amandla ajikelezayo afunekayo kwivalvu yebhabhathane ukuze ijikeleze into yayo yokuvala ebizwa ngokuba yi-"off seat torque".

I-actuator inokuba yeyomatshini okanye ezenzekelayo, kwaye ukuhamba kombhobho kunokulungiswa ngokushukumisa idiski yevalvu. Xa ivaliwe, idiski yevalvu igubungela umngxuma wevalvu, kwaye ulwelo luhlala ludibana nediski yevalvu. Oku kuya kubangela ukwehla koxinzelelo. Ukutshintsha indawo yediski ukuze inike indlela ukuhamba kolwelo, jika isiqu sijike ngekota.
