Imishini yokuvala ama-valve ayizingxenye ezibalulekile ekuqinisekiseni ukuphepha kwendawo yokusebenza, ikakhulukazi ezimbonini lapho ukukhululwa kwamandla ayingozi kuwukukhathazeka. Isigameko esisodwa esiphawulekayo esagqamisa ukubaluleka kwalezi zisetshenziswa senzeka ngo-2005 embonini yamakhemikhali eTexas. Ivalvu yavulwa kungaqondile ngesikhathi sokulungiswa okujwayelekile, okuholele ekuphumeni kwamagesi anobuthi nokuqhuma okuyinhlekelele. Lesi sigameko sigcizelele isidingo sephrothokholi ye-robust lockout/tagout (LOTO) ukuze kuvinjelwe ukwenziwa kusebenze okungagunyaziwe noma ngephutha kwemishini namasistimu. Sinalesi sizinda engqondweni, ake sihlole ukuthi ayini amadivaysi okuvala ama-valve, asetshenziswa kanjani, nokuthi kungani abalulekile.
Imishini yokuvala ama-valve ibalulekile ekuqinisekiseni ukuthi imishini nezinto zokusebenza zihlala zingenawo amandla ngokuphephile ngesikhathi kulungiswa futhi kulungiswa. Ngokuvala i-valve ngokoqobo endaweni, lezi zixhobo zivimbela ukukhululwa kwamandla ayingozi ngengozi, zivikela abasebenzi ekulimaleni okungase kube khona.
Ayini amadivayisi wokukhiya ama-Valve?
Imishini yokuvala ama-valve ayizindlela zokuphepha eziklanyelwe ukuhlukanisa imithombo yamandla ukuze kuqinisekiswe ukuthi imishini nezinto zokusebenza azikwazi ukwenziwa kusebenze ngenkathi kulungiswa noma kulungiswa. Lawa madivaysi eza ngezinhlobo ezahlukene futhi asetshenziswa ezimbonini lapho ukukhishwa okungahlosiwe kwamandla ayingozi kungase kubangele ubungozi obukhulu bokuphepha. Izinhlobo ezijwayelekile zihlanganisa ukuvala ama-valve ebhola, ukuvala ama-valve esango, nokuvalwa kwama-valve evemvane.
Inhloso eyinhloko yamadivayisi wokuvala ama-valve ukuhlinzeka ngomgoqo ongokoqobo ovimbela ukuxhashazwa kwe-valve. Lesi sithiyo siqinisekisa ukuthi i-valve ihlala endaweni ephephile, kungakhathaliseki ukuthi ivuliwe noma ivaliwe, kuye ngokuthi izidingo zenqubo yokulungisa. Ngokungeziwe ekukhiyweni okungokoqobo, lawa madivayisi ngokuvamile ahlanganisa indlela yokumaka enikeza ulwazi olubalulekile mayelana nesimo sokukhiya ngaphandle, njengegama lomuntu onesibopho sokuvala ngaphandle kanye nedethi esetshenziswe ngayo.
Izinhlobo zamadivayisi wokukhiya ama-Valve
Kunezinhlobo ezimbalwa zemishini yokuvala ama-valve, ngayinye yakhelwe ukuthwala ukumiswa kwama-valve ahlukene kanye nezinhlelo zokusebenza. Ukuqonda izinhlobo ezahlukahlukene kungasiza ekukhetheni idivayisi efanele izidingo ezithile:
I-Ball Valve Lockouts
Ukuvala ama-valve ebhola kuklanyelwe ukuthi kulingane phezu kwesibambo samavalvu ebhola, okuvimbele ngempumelelo isibambo ukuthi singaphendulwa. Lokhu kukhiya kuvame ukulungiseka ukuze kuthwale ububanzi bosayizi bezibambo. Asetshenziswa kabanzi ngoba ama-valve ebhola ajwayelekile ezindaweni eziningi zezimboni.
Idivayisi isebenza ngokufaka isibambo kukhava yokuvikela evikelwe ngokhiye. Izisebenzi ezigunyaziwe kuphela ezinokhiye noma inhlanganisela ezingasusa ilokhi, ziqinisekise ukuthi ivalvu ayikwazi ukuvulwa noma ukuvalwa kungahlosiwe. Lolu hlobo lokuvala ngaphandle luwusizo ikakhulukazi ezinqubweni ezibandakanya uketshezi noma amagesi, lapho ukuvuleka ngephutha kungaholela ekuchithekeni, ukuvuza, noma ukwakheka kwengcindezi eyingozi.
