Umhlahlandlela Ophelele Wamadivayisi Okukhiya Ama-Valve

Amadivayisi okukhiya ama-valve ayizici ezibalulekile ekuqinisekiseni ukuphepha emsebenzini, ikakhulukazi ezimbonini lapho ukukhishwa kwamandla ayingozi kuyinkinga. Isigameko esisodwa esiphawulekayo esagcizelela ukubaluleka kwala madivayisi senzeka ngo-2005 esitshalweni samakhemikhali eTexas. I-valve yavulwa ngengozi ngesikhathi sokulungiswa okuvamile, okwaholela ekukhishweni kwamagesi anobuthi kanye nokuqhuma okukhulu. Lesi sigameko sagcizelela isidingo sezinqubo eziqinile zokukhiya/ukukhiya (LOTO) ukuvimbela ukusebenza okungagunyaziwe noma okungaqondile kwemishini nezinhlelo. Sinalesi sizinda engqondweni, ake sihlole ukuthi ayini amadivayisi okukhiya ama-valve, ukuthi asetshenziswa kanjani, nokuthi kungani ebalulekile.

Amadivayisi okukhiya ama-valve abalulekile ekuqinisekiseni ukuthi imishini nemishini zihlala zingasebenzi kahle ngesikhathi sokulungiswa nokulungiswa. Ngokukhiya i-valve endaweni yayo, la madivayisi avimbela ukukhishwa kwamandla ayingozi ngengozi, avikele abasebenzi ekulimaleni okungenzeka.

Ayini Amadivayisi Okukhiya Amavalvu?

Amadivayisi okukhiya ama-valve ayizindlela zokuphepha ezenzelwe ukuhlukanisa imithombo yamandla ukuqinisekisa ukuthi imishini nemishini ayikwazi ukusebenza ngenkathi kulungiswa noma kulungiswa. Lawa madivayisi eza ngezindlela ezahlukene futhi asetshenziswa ezimbonini lapho ukukhishwa kwamandla ayingozi okungahlosiwe kungadala izingozi ezinkulu zokuphepha. Izinhlobo ezivamile zifaka phakathi ukukhiya ama-valve ebhola, ukukhiya ama-valve esango, kanye nokukhiya ama-valve e-butterfly.

Inhloso eyinhloko yamadivayisi okukhiya ngaphandle kwe-valve ukuhlinzeka ngesithiyo esingokoqobo esivimbela ukuphathwa kwe-valve. Lesi sisithiyo siqinisekisa ukuthi i-valve ihlala isendaweni ephephile, kungakhathaliseki ukuthi ivuliwe noma ivaliwe, kuye ngezidingo zenqubo yokulungisa. Ngaphezu kokukhiya okungokoqobo, la madivayisi avame ukufaka indlela yokumaka enikeza ulwazi olubalulekile mayelana nesimo sokukhiya ngaphandle, njengegama lomuntu ophethe ukukhiya kanye nosuku okwasetshenziswa ngalo.

Izinhlobo Zamadivayisi Okukhiya Amavalvu

Kunezinhlobo eziningana zamadivayisi okukhiya ama-valve, ngalinye lenzelwe ukwamukela ukucushwa kanye nezinhlelo zokusebenza zama-valve ezahlukene. Ukuqonda izinhlobo ezahlukene kungasiza ekukhetheni idivayisi efanele izidingo ezithile:

Ukukhiya Amavalvu Ebhola

Ukukhiya kwamavalvu ebhola kuklanyelwe ukulingana phezu kwesibambo samavalvu ebhola, okuvimbela ngempumelelo isibambo ukuthi singaphendulwa. Lokhu kukhiya ngokuvamile kuyalungiseka ukuze kuhambisane nobukhulu obuhlukahlukene bezibambo. Kusetshenziswa kabanzi ngoba amavalvu ebhola avamile ezindaweni eziningi zezimboni.

Idivayisi isebenza ngokufaka isibambo ekhava elivikelayo eliboshwe ngengidi. Abasebenzi abagunyaziwe kuphela abanokhiye noma inhlanganisela abangasusa ingidi, baqinisekise ukuthi i-valve ayikwazi ukuvulwa noma ukuvalwa ngengozi. Lolu hlobo lokukhiya luwusizo ikakhulukazi ezinqubweni ezihilela uketshezi noma amagesi, lapho ukuvulwa ngengozi kungaholela ekuchithekeni, ukuvuza, noma ukwakheka kwengcindezi okuyingozi.
