1. Ukugcinwa kwe-valve
Inhloso yokugcina nokugcinwa ukuvimbela i-valve ukuthi ingalimazi noma yehliswe ngekhwalithi ngesikhathi sokugcinwa. Eqinisweni, ukugcinwa okungalungile kungenye yezizathu ezibalulekile zokulimala kwe-valve.
Isitoreji se-valve, kufanele sihleleke kahle, ama-valve amancane eshalofini, ama-valve amakhulu angabekwa ngobunono endaweni yokugcina impahla, angahlelekile, ungavumeli indawo yokuxhumana ye-flange ithintane ngqo nomhlabathi. Lokhu akukona nje kuphela ubuhle, kodwa okubaluleke nakakhulu ukuvikela i-valve ekulimazeni. Ngenxa yokugcinwa okungalungile noma ukuphatha, i-handwheel iphukile, i-valve stem igxiliwe, i-nut ehleliwe ye-handwheel kanye ne-valve stem ikhululekile futhi ilahlekile, njll, lokhu kulahlekelwa okungadingekile kufanele kugwenywe.
Kuvalvu engasetshenziswa okwesikhashana esikhathini esifushane, ukupakishwa kwe-asbestos kufanele kususwe ukuze kugwenywe ukugqwala kwe-electrochemical kanye nokulimala kwesiqu.
I-valve yokungena kanye ne-outlet kufanele ivalwe ngephepha le-wax noma ishidi lepulasitiki ukuvimbela ukungena kwezinto ezingcolile ezithinta i-valve.
I-valve ingagqwala emkhathini, kufanele igcotshwe ngamafutha e-anti-rust, ukuvikela, qaphela ukugqwala.
Ama-valve angaphandle kumele ambozwe ngezinto ezingangeni emanzini nezingangeni uthuli njenge-linoleum noma i-tarp. Indawo lapho kugcinwa khona i-valve kufanele igcinwe ihlanzekile futhi yomile.
I-valve kufanele igcinwe kanjani
2. Ukusetshenziswa nokugcinwa kwevalvu
Inhloso yokusetshenziswa nokugcinwa kwe-valve ukwandisa impilo yesevisi ye-valve nokuqinisekisa ukuvulwa nokuvalwa okuthembekile.
Izintambo ze-stem, ezivame ukungqubuzana ne-stem nut, zidinga ukugcotshwa ngamafutha omile ophuzi, i-molybdenum disulfide noma impushana yegraphite ukuze kugcotshwe.
Ungavamisi ukuvula nokuvala i-valve, kodwa futhi ukuguqula njalo isondo lesandla, engeza i-lubricant kumcu we-stem, ukuvimbela ukuluma.
Kuma-valve angaphandle, imikhono evikelayo kufanele yengezwe esiqwini se-valve ukuvimbela imvula, iqhwa, uthuli nokugqwala. Uma i-valve ingumshini, fika ngesikhathi ku-gearbox thanda uwoyela wokugcoba.
Gcina i-valve ihlanzekile.
Hlala unamathela futhi ulondoloze ubuqotho bengxenye ye-valve. Uma i-nati ehleliwe ye-handwheel iwa, kufanele ifaniswe futhi ayikwazi ukusetshenziswa kahle, ngaphandle kwalokho izogaya isikwele esiphezulu se-valve stem, kancane kancane ilahlekelwe ukwethembeka futhi ingakwazi ukuqala.
Ungasebenzisi i-valve ukuthwala eminye imithwalo esindayo, ungami ku-valve, njll
Isiqu, ikakhulukazi udelela ingxenye intambo, ngokuvamile Sula, okokugcoba iye yangcoliswa uthuli esikhundleni esisha, ngoba uthuli iqukethe imfucumfucu shadow, kulula ukugqoka intambo kanye stem surface, kuthinta ukuphila service valve.
Ivalvu esebenza kufanele igcinwe kanye njalo ngekota, kanye nengxenye yonyaka ngemva kokuba isiqalile ukusebenza, kanye ngonyaka ngemva kokuba isiqalile ukusebenza, futhi ivalvu kufanele igcinwe ngaphambi kobusika njalo ngonyaka. Yenza umsebenzi we-valve oguquguqukayo futhi ushaye phansi kanye ngenyanga.
3. Ukugcinwa kokupakisha
Ukupakisha kuhlobene ngokuqondile nokuthi ukuvuza kwenzeka yini lapho i-valve ivuliwe futhi ivala izingxenye ezibalulekile zokuvala, uma ukupakisha kwehluleka, okuholela ekuvuzeni, i-valve ilingana nokwehluleka, ikakhulukazi i-valve yepayipi le-urea, ngoba izinga lokushisa layo liphakeme kakhulu; ngakho-ke ukugqwala kubi kakhulu, ukupakisha kulula ukuguga. Ukuqinisa isondlo kungandisa impilo yokupakisha.
Lapho i-valve ishiya ifektri, ngenxa yokushisa nezinye izici, kungase kube khona i-extravasation, ngakho-ke kuyadingeka ukuqinisa i-nati ezinhlangothini zombili ze-gland yokupakisha ngesikhathi, inqobo nje uma ingavuzi, bese uqinisa futhi. icala le-extravasation, ungaqinisi kanye, ukuze ungalahlekelwa ukuguquguquka kokupakisha nokulahlekelwa kokusebenza kokuvala.
Enye i-valve epakishwa nge-molybdenum dioxide lubrication paste, uma isetshenziselwa izinyanga ezimbalwa, kufanele ifakwe kugrisi yokugcoba ehambisanayo ngesikhathi, lapho kutholakala ukuthi ukupakisha kudinga ukwengezwa, kufanele kwengezwe ekupakisheni okuhambisanayo ngesikhathi ukuze kuqinisekiswe. ukusebenza kokubekwa uphawu.
4. Ukugcinwa kwezingxenye zokudlulisela
I-Valve ngesikhathi sokushintsha, uwoyela wokuqala wokugcoba uzoqhubeka nokulahlekelwa, kuhambisana nezinga lokushisa, ukugqwala neminye imiphumela, kuzokwenza ukuthi amafutha okugcoba ahlale omile. Ngakho-ke, ingxenye yokudlulisela ye-valve kufanele ihlolwe njalo, ithole ukuthi kufanele igcwaliswe ngesikhathi, qaphela ukugqoka okwenyuka ngenxa yokuntuleka kwe-lubricant, okuholela ekudluliseni okuguquguqukayo noma ukuhluleka kwe-jam kanye namanye amaphutha.
5. Ukugcinwa komjovo we-valve grease
Lapho i-valve igcotshwa, inkinga yokuthi amafutha angakanani ngokuvamile awanakwa. Ngemuva kokuthi i-valve igcotshwe, opharetha ukhetha imodi yokuxhuma ye-valve namafutha ukuze enze umsebenzi wamafutha. Kunezimo ezimbili: ngakolunye uhlangothi, umjovo omncane wamafutha uholela ekujovweni kwamafutha okwanele, futhi indawo yokuvala isheshisa ukuguga ngenxa yokuntuleka kokugcoba. Ngakolunye uhlangothi, umjovo wamafutha ngokweqile, okuholela ekumosheni. Akukho ukubala okunembile kwamakhono ahlukene okuvala ama-valve okusekelwe ohlotsheni lwe-valve nesigaba. Umthamo wokuvala ungabalwa ngosayizi we-valve kanye nohlobo, bese kuba umjovo ozwakalayo wamafutha afanele.
Izinkinga zokucindezela ngokuvamile azinakwa ekujovweni kwe-valve grease. Enkambweni yokujova amafutha, ingcindezi yomjovo wamafutha inenani eliphakeme elivamile kanye noshintsho lwesigodi. Uma ingcindezi iphansi kakhulu, ukuvuza kophawu noma ukwehluleka, uma ingcindezi iphezulu kakhulu, imbobo yomjovo wamafutha ivinjiwe, futhi i-grease cherry noma indandatho yokuvala uphawu ikhiywa ngebhola le-valve ne-valve plate. Imvamisa, lapho ingcindezi yokujova igrisi iphansi kakhulu, igrisi ejovwe igelezela ngaphansi kwegumbi le-valve, elivame ukwenzeka kumavalvu esango amancane. Uma umfutho womjovo wamafutha uphezulu kakhulu, ngakolunye uhlangothi, hlola umlomo womjovo wamafutha bese uwushintsha uma ukuvaleka kwembobo yamafutha kukhonjwa. Ngakolunye uhlangothi, amafutha aqinile. Uketshezi lokuhlanza kufanele lusetshenziselwe ukuthambisa igrisi ehlulekayo yokuvala ngokuphindaphindiwe bese ujova amafutha amasha ukuze esikhundleni salo. Ngaphezu kwalokho, uhlobo lokuvala kanye nezinto zokubeka uphawu nazo zithinta ingcindezi yomjovo wamafutha, amafomu ahlukene okuvala anomfutho ohlukile womjovo wamafutha, ngokuvamile, ingcindezi yomjovo we-grease seal eqinile iphakeme kunophawu oluthambile.
Lapho ugcoba i-valve, naka inkinga yokuma kwe-valve switch. Ukugcinwa kwe-valve yebhola ngokuvamile kusesimweni esivulekile, izimo ezikhethekile zikhetha ukuvala ukulungiswa. Amanye ama-valve akufanele avuleke. I-valve yesango ekunakekelweni kwayo kufanele ibe sesimweni esivaliwe, qinisekisa ukuthi amafutha eduze nendandatho yophawu egcwele umsele wokuvala. Uma ivuliwe, vala amafutha ngqo ku-flow noma i-valve cavity, okuholela ekumosheni.
Umphumela womjovo we-valve grease ngokuvamile awunakwa. Ingcindezi, inani lamafutha kanye nendawo yokushintsha konke kujwayelekile ekusebenzeni komjovo wamafutha. Kodwa-ke, ukuze kuqinisekiswe umphumela wamafutha we-valve, ngezinye izikhathi kuyadingeka ukuvula noma ukuvala i-valve, hlola umphumela wokugcoba, uqinisekise ukuthi ibhola le-valve noma i-lubrication surface yesango iyunifomu.
Lapho umjovo wamafutha, kufanele kuqashelwe ukukhucululwa kwendle emzimbeni we-valve kanye nezinkinga zokunciphisa ingcindezi yokuvinjwa kukasilika. Ngemuva kokuhlolwa kwengcindezi ye-valve, igesi namanzi ekamelweni elivaliwe le-valve yekamelo kuzokwandisa ingcindezi ngenxa yokwanda kwezinga lokushisa elizungezile, futhi ukukhishwa kwengcindezi yokukhishwa kwendle kufanele kwenziwe kuqala ukuze kube lula ukusebenza kahle komjovo wamafutha. Ngemuva komjovo wamafutha, umoya kanye nomswakama endaweni evaliwe kuyasuswa ngokuphelele. Ukucindezelwa kwegumbi lokukhipha ngesikhathi esifanele, kodwa futhi nokuqinisekisa ukuphepha kokusetshenziswa kwe-valve. Ngemuva komjovo wamafutha, idrayivu kanye nentambo yokunciphisa ukucindezela kufanele iqiniswe ukuze kuvinjelwe ukwenzeka kwezingozi.
Umjovo wamafutha kufanele futhi ubheke ububanzi bevalvu kanye nenkinga yokushaywa kwesihlalo sendandatho yokuvala. Isibonelo, i-valve yebhola, uma kukhona ukuphazamiseka, ungalungisa umkhawulo wokuvula ngaphakathi, uqinisekise ukuthi ububanzi buqondile ngemva kwelanga. Lungisa umkhawulo awukwazi nje ukuqhubeka nokuvula noma ukuvala isikhundla, ukuze ucabangele konke. Uma indawo yokuvula ilingana futhi ukuvala kungekho endaweni, i-valve izovalwa ngokukhululekile. Ngokufanayo, lungisa ukushintsha endaweni, futhi ucabange ukulungiswa okuhambisanayo kwendawo evulekile. Qinisekisa ukuthi i-Engeli engakwesokudla ye-valve.
Ngemuva komjovo wamafutha, qiniseka ukuthi uvala inombolo yomlomo womjovo wamafutha. Gwema ukungcola, noma gcoba amafutha emlonyeni, ikhava ukuze ugcobe amafutha avimbela ukugqwala, ukuze ugweme ukugqwala. Okokusebenza okulandelayo.
I-actuator kagesi ye-valve yesiteshi samandla yethulwa indawo ekhombisa isheke ledivayisi (3), ama-actuator kagesi afakwe ebhentshini lokuhlola, isikhombisi se-ejensi yenkomba ye-valve siye endaweni “ehlezi”, ama-actuator kagesi aqala ukungalayishi, hlola i-pointer ngokuphumayo. ukuzungezisa ku-shaft, lapho umthetho wokufinyelela endaweni ethile “evulekile” (njenge-valve), Inqubo yokuzungezisa kanye nendawo yesikhombi kuzohambisana nezinhlinzeko ze-5.2. 10, futhi inani lokuhlolwa akufanele libe ngaphansi izikhathi ezintathu. Ukuhlolwa kokusebenza kokuvikela indawo ebiyelwe kuzokwenziwa ngokuhambisana ne-GB 4208 futhi imiphumela izohambisana no-6.1.2.
