Umsebenzi wokukhiya i-valve
Uma kukhulunywa nge-lockout tagout, i-valve lockout inemisebenzi elandelayo:
- Ukulawula ukuphepha:Ukukhiya amavalvu kungavimbela amavalvu ukuthi asebenze ngaphandle kwemvume noma ngengozi, ngaleyo ndlela kugwenywe ukuvuza, umonakalo wemishini, ngisho nezingozi zokuphepha ezibangelwa ukuvulwa noma ukuvalwa kwamavalvu okungalungile.
- Ukuvimbela ukusebenza kabi:Ekukhiqizweni kwezimboni, amavalvu adinga ukunakekelwa nokulungiswa. Ukukhiywa kwamavalvu kungawavala amavalvu phakathi nalezi zinqubo ukuvimbela izingozi ezibangelwa ukunganaki noma ukusebenza okungafanele.
- Umphumela wesexwayiso:Ukukhiya ivalvu nokumaka kungaxwayisa abanye abasebenzi ukuthi baqaphele ukuthi ivalvu ikhiyiwe futhi ayikwazi ukusondelwa noma ukusetshenziswa ngokuthanda kwabo, okusebenza njengomsebenzi wokuxwayisa.
- Ukuqinisekisa isimo sokuphepha kwemishini:Ngokukhiya amavalvu, kungaqinisekisa ukuthi imishini ivaliwe ngokuphelele futhi ihlala isesimweni esiphephile, kuvimbele imishini ukuthi iqale ngengozi, okubangela ukulimala noma ukufa.
Izinto ezisetshenziswa kakhulu zokukhiya ama-valve kanye nezizathu zokukhetha kwazo yilezi ezilandelayo:
- Inayiloni:Inokumelana okuhle nokushayisana kanye nokuqina kwamakhemikhali, imelana nokugqwala, futhi ingagcina ukusebenza kahle ezindaweni ezinzima.
- Ipulasitiki yobunjiniyela be-ABS:Inamandla aphezulu, ukumelana okuhle nokushayisana, futhi ingabunjwa ibe yizimo ezahlukahlukene ukuze ivumelane nezinhlobo ezahlukene zamavalvu.
- I-Polypropylene:Inokumelana okuhle nokushaqeka, imelana nokugqwala kwamakhemikhali, futhi iqinile futhi ihlala isikhathi eside.
- I-Polytetrafluoroethylene:Inokumelana okuhle kakhulu nokugqwala kanye nokumelana nokuguguleka, futhi ivame ukusetshenziswa njengesihlalo sevalvu noma izinto zomphezulu we-diaphragm zamavalvu.
- Insimbi yezinga lezimboni: Inamandla aphezulu futhi ihlala isikhathi eside, ifanelekela izindawo eziningi zezimboni, futhi ingavimbela ngempumelelo amandla angaphandle ukuthi angonakalisi.
- Insimbi engagqwali:Inamandla okumelana nokugqwala futhi ifaneleka ezindaweni ezishisa kakhulu, ezinomswakama ophezulu noma ezindaweni ezinokugqwala kwamakhemikhali. Isibonelo, insimbi engagqwali ye-austenitic, insimbi engagqwali ekhethekile, njll., ifaneleka ezindaweni ezahlukene zokugqwala.
