Ukufakwa kwama-valve ebhola ashiselwe ngokugcwele
(1) Ukuphakamisa. I-valve kufanele iphakanyiswe ngendlela efanele. Ukuze uvikele isiqu se-valve, ungabophi iketango lokuphakamisa isandla, i-gearbox noma i-actuator. Ungawasusi amakepisi okuvikela kuzo zombili iziphetho zomkhono wevalvu ngaphambi kokushisela.
(2) Ukushisela. Ukuxhumana nepayipi eliyinhloko kushiselwe. Izinga le-welding seam kufanele lihlangabezane nezinga elithi "Radiography of Welded Joints of Disk Flexion Fusion Welding" (GB3323-2005) Grade II. Ngokuvamile, i-welding eyodwa ayikwazi ukuqinisekisa ngokugcwele zonke iziqu. Ngakho-ke, lapho u-oda ivalvu, umenzi kufanele acele umenzi ukuthi angeze u-1.0m kuzo zombili iziphetho zevalvu. I-sleeve tube, uma i-welding seam ingafanelekile, kunobude obanele bokusika i-welding seam engafaneleki futhi i-weld kabusha. Lapho i-valve yebhola kanye nepayipi kushiselwe, i-valve kufanele ibe sendaweni evuleke ngokugcwele engu-100% ukuze ivimbele ukuthi i-valve yebhola ingalinyazwa ngokufafaza i-slag yokushisela, futhi ngesikhathi esifanayo uqinisekise ukuthi i-valve Izinga lokushisa lophawu lwangaphakathi alilimazi. idlule ku-140 degrees Celsius, futhi izinyathelo ezifanele zokupholisa zingathathwa uma kunesidingo.
(3) Ukwakhiwa kwe-valve kahle. Isebenzisa ukwakheka okukhethekile futhi inezici zokungakhathaleli. Ngaphambi kokungcwaba, sebenzisa i-Pu ekhethekile evimbela ukugqwala ngaphandle kwe-valve. Isiqu se-valve sinwetshwa ngokufanelekile ngokuya ngokujula komhlaba, ukuze abasebenzi bakwazi ukuqedela imisebenzi ehlukahlukene phansi. Ngemva kokungcwatshwa okuqondile, kwanele ukwakha isandla se-valve encane kahle. Ngezindlela ezivamile, azikwazi ukungcwatshwa ngokuqondile, futhi imithombo emikhulu ye-valve idinga ukwakhiwa, okuholela endaweni evaliwe eyingozi, engafaneleki ekusebenzeni okuphephile. Ngesikhathi esifanayo, umzimba we-valve ngokwawo kanye nezingxenye zokuxhuma umshudo phakathi komzimba we-valve nepayipi kuzogqwala, okuzothinta impilo yesevisi ye-valve.
Yini okufanele inakwe ekugcinweni kwe-valve yebhola eboshwe ngokugcwele?
Iphuzu liwukuthi esimweni esivaliwe, kusekhona uketshezi olucindezelwe ngaphakathi komzimba we-valve.
Iphuzu lesibili ukuthi ngaphambi kokulungiswa, qala ngokukhulula umfutho wepayipi bese ugcine i-valve isendaweni evulekile, bese unqamula umthombo wamandla noma wegesi, bese ukhipha i-actuator kubakaki, futhi ngemva kwalokho konke okungenhla kungase kulungiswe. .
Iphuzu lesithathu ukuthola ukuthi ukucindezelwa kwamapayipi akhuphuka nomfula we-valve yebhola akhululiwe ngempela, bese ukuhlakazeka nokubola kungenziwa.
Amaphuzu amane kufanele aqaphele ekuhlakazweni nasekuhlanganiseni kabusha, ukuvimbela ukulimala endaweni yokuvala izingxenye, ukusebenzisa amathuluzi akhethekile ukususa i-O-ring, nokuqinisa amabhawodi ku-flange ngokulinganayo futhi kancane kancane futhi ngokulinganayo. ngesikhathi sokuhlangana.
Amaphuzu amahlanu: Lapho uhlanza, i-ejenti yokuhlanza esetshenzisiwe kufanele ihambisane nezingxenye zenjoloba, izingxenye zepulasitiki, izingxenye zensimbi kanye nendawo yokusebenza ku-valve yebhola. Lapho indawo yokusebenza iyigesi, uphethiloli ungasetshenziswa ukuhlanza izingxenye zensimbi, futhi Ezingxenyeni ezingezona ezensimbi, udinga ukusebenzisa amanzi ahlanzekile noma utshwala ukuhlanza. Izingxenye ezibolile ezibolile zihlanzwa ngokuwashwa ngokucwiliswa emanzini, kanti izingxenye zensimbi zezingxenye ezingezona ezensimbi ezingakaboli ziyakhuhlwa ngendwangu kasilika ehlanzekile necolekileyo ecwiliswe ku-ejenti yokuhlanza, futhi wonke amafutha anamathele odongeni kufanele ahlanganiswe. isusiwe. , ukungcola nezintuli. Futhi, ayikwazi ukuqoqwa ngokushesha ngemva kokuhlanza, futhi ingenziwa kuphela ngemva kokuba i-ejenti yokuhlanza iqhume.
