I-valve yokupaka ngezandla zayo. Indlela yokugcoba ama-valves ngezandla zakho ngaphandle kwamathuluzi?

Lapho ulungisa injini, ukuvama kwama valve kuvame ukudingeka . Lo msebenzi obalulekile, okudingeka ukuthi ube nethuluzi elifanele. Yiqiniso, ungenza ngaphandle kwalo. Ngakho-ke, ukulayishwa kwama valve kusingathwa kanjani?

Uma ukuphoqa kuyadingeka

Abaningi basebenzisa ithuluzi elikhethekile, ukunamathisela kanye nokulinywa lokugaya ama-valve. Kodwa-ke, akubona wonke umuntu owazi kahle ukuthi le nqubo iyenzeka kanjani. Izikhwama namagagasi anezinhlobo ezimbalwa zeziphambeko:

• Ama-chamfers agcwele ama-shells noma i-carbon deposits, kodwa isimo sabo asishintshiwe;
• Ama-chamfers agcwele ikhabhoni namagobolondo, ngenkathi isimo sabo sishintshwa.

Esikhathini esilandelayo, into enjengezinyathelo ingahle ibe phezu kwendawo. Ngaphezu kwalokho, ukuma kwesimo se-chamfer kungashintsha futhi kuhlanganiswe.

Izici ezishaya kuzo zombili izimo

Uma isimo se-chamfer singaphuki, ukukhishwa okujwayelekile kwenziwa. Uma kukhona amaphutha, ingxenye iqhutshwa kuqala nge-lathe, futhi izihlalo ze-valve zihlanjululwa ngezigaxa ezinama-cones. Okubaluleke kakhulu yizilinganiso zamadivayisi.

Ukuze uqale, isihlalo se-valve sinomshini nge-angle engama-45 °, khona-ke iqembu eliphezulu liyakunqunywa nge-cutter ene-angle ye-15 °, futhi i-chamfer ene-angle ka-75 ° isusiwe engxenyeni engezansi yesihlalo. Kungenzeka futhi ukusingatha izingxenye ngamasondo ahlukumezayo kanye nokukhwabanisa isandla. Amathuluzi kumele abe nama-angles angu-45 °, 15 ° no-75 °.

Kumele kuqashelwe ukuthi ukugaya ama-valve ngesandla sokukhwabanisa noma isikhuntazi sithatha isikhathi esiningi. Ukusheshisa le nqubo, ungasebenzisa ithuluzi likagesi elikwazi ukuhlolwa kuzo zombili izinkomba, futhi futhi kancane kancane ujikeleze nxazonke.

I-Lapping unamathisele

Okokuqala, kunamathele adingekayo ukuze aphathe ama-valve. Yinto yokuqala okufanele uyithenge esitolo esikhethekile. Ngesikhathi ukwelashwa, unamathisela usetshenziswa ekugcineni kwe-valve. Ukwakheka okunjalo kuyisihlobo samaphilisi amancane. Ngenxa yokunamathisela, kulula ukumbamba i-valve ku-socket. Kunezinhlobo eziningana eziyinhloko zamathuluzi anjalo. Konke kunemibono ethile ethinta izindleko zokukhiqiza.

Ukuhlukaniswa kwama-pastes

I-paste yokugaya ama-valve ihlukaniswa ngokwezinga lezokwelapha okuphezulu: ngokuba ukwelashwa kokuqala - okukhulu, okwenziwe ukugcina. Le ndlela yokugcina ithandwa kakhulu, ngoba imikhiqizo enjalo iphakanyiswa ngabanikazi abasebenza ngenjini. Ukunamathiswa okuhle okunamakhompi kukuvumela ukuthi usule ama-valve masinyane nangendlela efanele. Kulokhu, kuncike kakhulu ekubunjweni kwezindlela, kodwa esimweni sezinkampani kanye nemininingwane ngokwayo. Ngaphezu kwalokho, ukusikwa kwama-valve ngezandla zabo akutholakali njalo kuwo wonke umuntu. Lapho ukucubungula kunconywa ukuba usebenzise ukwakheka okuvamile, izindleko zazo eziyi-ruble eziyi-100 nge-tube.

Ungathengi i-pasta ebiza kakhulu. Uma kunesidingo kuwo, ungayithenga kuhlelo.

"Umkhulu" womkhulu

Ukweqa amagagasi ngezandla zakho kuyindlela elula, uma wazi nokuthi kufanele ukwenze kanjani. Esikhathini esidlule, kwakunezinsimbi zokukhanda ikhanda le-cylinder. Idivayisi enjalo yokugaya ama-valve yayisetshenziswe ngokuyinhloko ukubuyisela izikhwama zezingxenye. Amanye amakhosi aye asebenzisa ithuluzi elinjalo kuze kube yilolu suku. Ngaphandle idivaysi iyimbubu yesokhethi, eyenziwe ngesimo se-valve. I-cutter ihlelwe ku-drill. Idivaysi encane futhi ifana nohlobo lwensimbi.

Ingabe njalo sidinga abaduki?

Ingabe insimbi enjalo iyadingeka? Ukuze uphendule umbuzo obhekene nawo, kubalulekile ukubuka izikhwama ezicindezelwe ezihlokweni. Uma ubuqotho babo bephulwa, ungaqhubeka nokugaya. Uma zonakalisiwe, isibonelo ngokushisa, ngakho-ke kunconywa ukuphatha ngazo izigaxa ezikhethekile. Ubuchwepheshe kulokhu bulula kakhulu. Ekuqaleni, kunconywa ukuba ushintshe iziqondiso bese uwagaya. Esimweni ngasinye, indlela yokusebenza iyadingeka. Ungathenga idivayisi ekhethekile yokugaya ama-valve cishe noma yisiphi isitolo esikhethekile.

Noma mhlawumbe ufake ama-valve amasha?

Ama-valve amasha awadingeki ngaso sonke isikhathi. Yiqiniso, uma imininingwane ivinjiwe kancane, ungazami ukuvumelanisa. Inqubo ngeke isebenze, futhi uzochitha isikhathi sakho namandla. Kulesi simo, kungcono ukuvakashela isitolo ngezingxenye ezithintekayo zezimoto futhi uthenge ithikithi entsha.

Uma kususwa izingxenye, ukunakwa okukhethekile kufanele kunikezwe ikhwalithi yabo. Ukuphakama kwama-valve kufanele kube kunoma yikuphi okufanayo. Ukutholakala kobudlova nokukhwabanisa emaphethelweni, izintambo nokugcizelela izinsimbi ze-bevels ezisebenzayo akuvumelekile. Kunconywa ukuthi uphonse izingxenye ngaphambi kokuba ukhanyise ukufaka i-kit entsha. Le nqubo akufanele yenziwe kuphela ezindongeni ze-valve, kodwa nangentanyeni emnyama ye-valve, naseplanethi ephathekayo. Ngenxa yalokhu kucubungula, izingxenye zizoba yi-carbon encane nokushisa. Uma usebenza, ama-chamfers we-seal ayinconywa. Kufanele baxubane kuphela ngokumelene ne-saddles.

Umshini wokugaya ama-valve

Amaningi we-valve yokugaya enza amadivayisi akhethekile. Lokhu kungadinga i-hose yerabhabhu kanye ne-drill evamile. Ukukhishwa kwamagagasi ngezandla zabo kulokhu kwenzeka ngokulandela uhlelo olulandelayo:

1. I-hose ye-Rubber ifakwa kwi-drill. Lokhu kungadinga ukushayela kanye nezimbambo eziningana.
2. Ekupheleni kwephasi, kufakwa isicelo sokunamathisela.
3. Elinye lama-valves enjini lifakwa kule hose. Ukulungiswa okunokwethenjelwa, ungasebenzisa izikhalazo.
4. I-valve ifakwe engxenyeni, futhi i-lapping yayo iqala.

Ngale ndlela kubaluleke kakhulu ukuthi ungafaki isivinini esiphezulu ku-drill. Inqubo kumele iqhubeke kancane futhi ngokunembile. Ngokuqondene nezinguquko, kufanele kube kusuka ku-400 kuya ku-500 ngomzuzu. Lapho ijubane likhuphuka, ama-sanddles namabhande we-valve ashisa kakhulu. Inqubo yokugaya akukhuthazwa ukwenza izinyathelo eziyindilinga. Kubalulekile ukulinganisa ukusebenza kwe-valve injini, ngenkathi kuqhubekela phambili, bese ubuyela emuva.

Kumele kuqashelwe ukuthi ukugaya ama-valve nge-drill kanye ne-hose kuyinkqubo ebuhlungu eyenza isikhathi eside.
