Iyini i-Globe Valve

Ezinhlelweni zamapayipi ezimboni, ukwakhiwa kwamanzi kanye nokugeleza kwamanzi, kanye nezimo ezahlukahlukene zokulawula uketshezi, i-globe valve iyi-valve yokuvala ephoqelelwe esetshenziswa kabanzi. Umsebenzi wayo oyinhloko ukulawula ngokunembile ukugeleza kanye nokuvaleka kwemidiya (njengoketshezi, amagesi, umusi) ngaphakathi kwepayipi. Isebenza ngokuguqula ukunyakaza kokujikeleza kwesiqu kube ukunyakaza okuqondile, okuqondile kwediski—lapho ubuso bokuvala bediski bucindezela ngokuqinile ebusweni bokuvala isihlalo, indlela yokugeleza iyavalwa, futhi ukugeleza kwemidiya kuvinjiwe; lapho idiski iphakanyiswa kude nesihlalo, indlela yokugeleza iyavuleka, okuvumela imidiya ukuthi idlule, okuvumela ukulawula uketshezi okuguquguqukayo.

Izingxenye Eziyinhloko Zevalvu Yembulunga

Ukusebenza okuzinzile kwe-I-Globe Valveincike emsebenzini ohlanganisiwe wezingxenye eziningana ezibalulekile, ngayinye yenza umsebenzi othize ukuqinisekisa ukusebenza kokuvala kwevalvu kanye nokuthembeka kokusebenza.

Umzimba

Umzimba “uhlaka oluyinhloko” lwevalvu yomhlaba, ngokuvamile olwenziwe ngensimbi ephothiwe, insimbi yekhabhoni, insimbi engagqwali, noma ezinye izinto eziqinile nezimelana nokugqwala. Uqukethe isiteshi sokugeleza kwangaphakathi (ukungena kanye nokukhipha). Umzimba kumele umelane nengcindezi yemidiya engaphakathi kwephayiphi futhi uhlinzeke ngesisekelo sokufaka nokubeka izingxenye zangaphakathi njengesihlalo kanye nediski, okwenza kube yingxenye eyinhloko yamandla esakhiwo sonke.

Idiski

Idiski iyisici esiyinhloko sokuvala esilawula ukugeleza kwemidiya, ngokuvamile sisebenza ngokubambisana nepulaki kweminye imiklamo. Ukuma kwayo nezinto zayo kukhethwa ngokusekelwe ezicini zemidiya (isb. ukugqwala, izinga lokushisa, ingcindezi). Isibonelo, insimbi ivame kakhulu ezimweni zokucindezela okuphezulu, kuyilapho irabha noma ipulasitiki ingasetshenziswa ekusetshenzisweni kokugqwala okuphansi. Idiski ifinyelela ukuvalwa okuvaliwe ngokuhambisana eduze nesihlalo.

Isihlalo

Isihlalo “siyindawo yokubhekisela” yokuvala ivalvu yomhlaba, eqiniswe ngaphakathi komzimba esiteshini sokugeleza kwemidiya. Indawo yaso yenziwe ngomshini oqondile ukuqinisekisa ukuthintana okuqinile nendawo yokuvala idiski. Izinto zesihlalo zidinga ukuguguleka okuhle nokumelana nokuvala, ngokuvamile kufaka phakathi i-alloy yethusi, insimbi engagqwali, kanye ne-alloy eqinile ukulwa nokuguguleka kwesikhathi eside okuvela kumidiya nokwandisa impilo yesivalo sevalvu.

Isiqu

Isiqu "siyibhuloho lokudlulisa" elixhumanisa i-actuator nediski, ngokuvamile induku enentambo. Uhlangothi olulodwa lunamathele kudiski, kanti olunye luxhumeka ku-actuator (isb., isondo lesandla, injini kagesi). Iguqula amandla okushayela abe ukunyakaza okuqondile kwediski ngokunyakaza okujikelezayo. Isiqu kumele sibe namandla anele kanye nokumelana nokukhathala, futhi ubuso baso buvame ukufakwa i-chrome-plated noma i-nitride ukuze kuncishiswe ukungqubuzana nokuvimbela ukugqwala.
