Isigaxa valve kwezihlalo imoto

ukusebenza isikhathi eside futhi eziqinile injini imoto bathembele ngokuphelele ezintweni esimweni salo lobuchwepheshe. Ngeshwa, akukho ukunyakaza obuphakade, izingxenye ezinyakazayo ayafa sisondela ngokungenakuvinjelwa ngokuhamba kwesikhathi. Omunye izingxenye yangaphakathi omlilo injini ukulayishwa kukhona valve ekhanda isilinda. Ungeniswa uMbhalo nophethiloli ingxube ngesikhathi esifanayo, ngesikhathi sokusebenza, yingxenye izindonga ekamelweni amandla omlilo, ukunakekela yonke imiphumela okuphazamisayo. Ngakho-ke, valve ukulungisa - Usuqhubekile akunakugwenywa nokuqhutshwa injini. Ukuze kahle lokwenza lo msebenzi, amathuluzi akhethekile ziyadingeka. Ikakhulukazi, iqoqo bezihlahla kwezihlalo valve. Kodwa ukuqonda ukuthi kungani idingeka ngempela, kufanele kube kancane ujule le mfundiso.

isikhathi Kudivayisi

Njengoba sekushiwo, valve ake futhi ake aphume fuel ingxube ekamelweni injini amandla omlilo. Njengoba umjikelezo ijoka ipuleti kuthinta compressive amandla ingxube onqenqemeni amapuleti ugaye off a Isigaxa. Iwindi combustor Ubuye wotho elihambisana Isigaxa. Beka silingane ipuleti umphini emaphethelweni ewindini ibizwa ngokuthi sehhashi. On kahle kanjani into eduze kwamanzi, okuningi kuncike nemingcele ukusebenza injini yenqubo, kuhlanganise ezibaluleke kakhulu - kokucindezelwa.

I baqaphe valve ngeke banamathele esihlalweni sayo isikhundla avaliwe, le ukuvuza ngaphezulu uMbhalo kuyofezwa. Ngakho Kuyohlale kudingeka amandla okusebenza zigcinwe ngesikhatsi operation injini.

Isidingo ithuluzi ekhethekile iyokhandwa

valve izihlalo ngemva uyibanga elide nakanjani zingagugi. I chamfer phezu kwesihlalo ekugcineni kuba cylindrical ngaphezulu. Iwindi ngokwawo okusaqanda ngenxa yokuguga engalingani. Ukwephulwa geometry zingavela ngenxa okweqile yenjini lapho ikhanda block kuyinto esontekile kanye nemingcele yayo yejeyomethri kwashintsha. Futhi ungaveli igobolondo kobuso esihlalweni valve, ngqo isici.

Lezi ukukhubazeka kuholele ukuvuza egumbini amandla omlilo nomphumela elimazayo emphethweni waso. Ngakho-ke, ngesikhathi kulungiswe injini wokuhlola ayimpoqo owabeka isilinda ikhanda. Kwasetshenziswa ukugaya izindlela Saddles zabo ithuluzi ekhethekile, ikakhulukazi ngenxa ukulungisa Isigaxa valve izihlalo. Ngaphandle kwawo, it is hhayi kwenziwe yikuphi ukukhanda injini.

izinkomba speczinstrumenta

Ukusebenzisa umshini wokusika kwezihlalo umphini kulezi zimo ezilandelayo:

• ukulimala ebusweni ukusebenza Saddles ukuthi kungenziwa zibuyiswe;
• ngemva ethi awafike umphini ku izibuko;
• emva esikhundleni umphini Umhlahlandlela otshanini noma seatings;
• ngesikhathi imoto ukulungisa eziyinkimbinkimbi.

Kuzo zonke izimo, ukukhanda kungenzeka esebenzisa Izigaxa nemibandela igalaji, yebo, uma ifa amakhono zenhlangano injini kanye disassembly. Zonke umsebenzi kwenziwe ekhanda isilinda isusiwe.

ithuluzi kwebalingisi

Isigaxa kwezihlalo umphini - kudivayisi ngempela ayinzima ukuthi enze kahle imisebenzi yabo. Ngaphandle tapered okuyingxenye kuyinto umlomo wombhobho nge imbobo ngokusebenzisa. I evele side okunamathiselwe kukhona bezihlahla ekhethekile.

Lapho aboshelwe valve esihlalweni Isigaxa ukunyakaza ukujikeleza ungqimba chamfer ukusikeka. Yekuchumana unamathele kahle round ukuma. Umsiki ifomu elilodwa akunjalo - kuba njalo iqoqo Izigaxa ka-engeli lehlukene. I engela degrees 15 kuya ku-60 ngoba Saddles wotho ku izinjini ezahlukene ziyehluka. Futhi, ukwelashwa wenziwa izigaba eziningana, ne ukwenyuka kancane i-engeli. Ukuze usebenze ngokugcwele, kumelwe nakanjani babe wesitimela ovundlile. Kuqakatheke ngani? Umhlahlandlela ovundlile inikeza ukuqondanisa nokusingatha abushelelezi sehhashi phezu kwawo wonke selilonke.

Izici amathuluzi brand neWay

Umsiki for umphini izihlalo neWay - lamathuluzi ezidume kakhulu ethi awafike izihlalo valve futhi wokugaya. Isici kwaleli thuluzi kukhona bezihlahla ekhethekile. Ngosizo ukuba balungise izihlalo valve kulula ngokukhethekile ngaphandle ukusetshenziswa amandla ikakhulukazi ngokomzimba.

Leli thuluzi inhlukano ngokuphelele. Esinye isici esiphawuleka kuyashesha-pilot. Le divayisi efakwe kule iziqondiso valve. Ngenxa ngokunemba machining izingxenye ibangelwa okusezingeni eliphezulu ngokunemba wokugaya. Ngenxa yalokho, it akudingi okwalandela valve ethi awafike. Ingabe ngokushesha isilungele ukusebenza yenjini, ngaphandle ukugijima.

izindleko amathuluzi ukugaya

Iqoqo bezihlahla isihlalo umphini kuhlanganisa iqoqo Izigaxa of ubukhulu ezahlukene kanye engela, bezihlahla replaceable, kanti guide mpo. Ngosizo isethi yakamuva umgwaqo ebusweni zokusebenza. isethi Semi ka 6-10 tincenye production ezifuywayo has a izindleko ruble ayizigidi 1-3. amathuluzi Professional, ehlanganisa aqukethe izinto 13-15, kuwufanele ruble ecishe ibe yizinkulungwane 10-15.

Ngenxa amanani entengo aphezulu, lo Isigaxa kwezihlalo umphini isetshenziswa kuphela ku ukulungisa imoto. Cishe wonke amaqoqo angu - kukhona jikelele futhi sivumela Milling Saddles ngokugedla cishe kunoma iyiphi imoto. Kukhona futhi amakhithi eyenzelwe brand ethize. Ngokwesibonelo, kuba Saddles bezihlahla ngoba Vaz valve. Ifanele kokubili classical umshini emotweni lapho kuhlanganiswa khona umoya nomusi kaphethiloli onobuhle, kanye umjovo zanamuhla.

Ukulungiswa Saddles valve ethi awafike

izakhi yokutakula kusetshenziswa bezihlahla Milling futhi igaya kulandele ethi awafike. Lapho Milling isetshenziswa Izigaxa nge diameters ezahlukene nama-engeli. Okuvame kakhulu kuyinto engela 45 degrees. Ngokusho leliqhinga, wenza iningi Saddles of valve ku amakhanda isilinda, kuhlanganise izimoto yasekhaya. Bezihlahla ne-angela enkulu zisetshenziselwa qondanisa wotho wasinikeza ububanzi edingekayo.

Ngenxa yokuthi akuyona ngaso sonke isikhathi, ukulungisa ukwazi ukubaluleka esiqondile engela izihlalo wotho, ngokuzenzakalela iyona Izigaxa ukugijima kakhulu engeli kusukela degrees 30 kuya ku-60. Mills ezimbili ezahlukeneyo kungenzeka - I-"kanzima" metal amakhanda, futhi kucutshungulwa Saddles ezenziwe metal ethambile.

countersinks

Uma ukulungiswa angasetshenziswa ukuze countersink izihlalo Isigaxa valve. Yehluka abagawula ukufaka umshini wokusika non-esikhiphekayo (noma kwesinye isikhathi ngokomthetho). Inzuzo yalezi amadivaysi ukuthi bangakwazi ukwakha bonke ubuso zokusebenza esihlalweni ngokushesha.

Omunye umehluko itholakala enye indlela, ukufakwa ukwesekwa. Omunye ukwesekwa efakwe kwi emikhonweni valve, kwesibili - kwi ubakaki. Lokhu kwandisa kakhulu ngokunemba machining we ebusweni zokusebenza.

izihlalo yokulungisa valve

efiselekayo esikhundleni sehhashi ngaphambi inqubo ukucutshungulwa, noma ngisho ukuba balungise Umhlahlandlela valve. Kutakwakhela Umhlahlandlela Izigaxa. Ngemva kwalokho, ukucutshungulwa uya Izigaxa (Izigaxa) - kusukela komncane kuya engeli enkulu, uma valve izihlalo ezithile uyivumele. Icubungula ukwandisa chamfer inweba kufika ku 2 mm ububanzi ukuze valve eyanele kanye 2.5 mm for the qeda. Khona-ke ebusweni ukusebenza is iphucuziwe ukuze ususe noma ikuphi burrs. Ngesikhathi Saddles siphelile Milling ngqo.

Ayimpoqo yokugcina inqubo - ethi awafike valve. It ikuvumela ukuba uhlole indlela ngokunembile lidlule wokugaya. Ukuze ethi awafike, ukunamathisela ekhethekile olwalwenza nge uhlamvu esihle. Diamond ayinhlama akunconywa ngoba ziqukethe izinhlayiya okuqinile. Abakwazi okwengeziwe ukusheshisa bafake Saddles. Ukugaya kwenzeka ukunyakaza ukujikeleza kwesihlalo valve. Nakuba ngezikhathi ukukhulisa kanye valve ephansi pasta extruded futhi ithole phezu ukusebenza esihlalweni. Uma emva kwemizuzu 1-2 ebusweni akuyona ngakujwayela ke Milling wenziwa unsatisfactorily. kabusha ukucutshungulwa liyadingeka.

isiphetho

Milling izihlalo valve futhi igaya - umsebenzi Akunzima, kodwa kudinga ngokunemba high. Futhi lezi ukulungiswa zidinga amathuluzi akhethekile, okuyinto Isigaxa kwezihlalo valve. Uma ukusebenza ezifana oyokwenziwa akuvamile kube ukuhlakanipha ubheke ukugeza imoto.
