Ukugcinwa kwevalvu yemihla ngemihla
1. I-valve kufuneka igcinwe kwigumbi elomileyo kunye nelomoya, kwaye zombini iziphelo zepaseji kufuneka zivaliwe.
2. Iivalve ezigcinwe ixesha elide kufuneka zihlolwe rhoqo, ukungcola kufuneka kususwe, kwaye ioli echasene ne-rust kufuneka isetyenziswe kwindawo yokucubungula.
3. Emva kokufakela, ukuhlolwa rhoqo kufuneka kwenziwe.Izinto eziphambili zokuhlola:
(1) Ukunxitywa komphezulu wokutywina.
(2) Ukunxitywa kwentambo yetrapezoidal yesiqu kunye ne-stem nut.
(3) Ingaba ukupakisha kuphelelwe yisikhathi kwaye akuvumelekile, ukuba konakaliswe, kufuneka kutshintshwe ngexesha.
(4) Emva kweMANYANO ENYEIBHOLA VALVE X9201-TIGRAY igqitywe kwaye idityanisiwe, uvavanyo lokusebenza lokutywina kufuneka lwenziwe.
Umsebenzi wokulungisa ngexesha lokutofa kwegrisi yevalvu
Umsebenzi wokugcinwa kwevalve phambi kwe-welding kwaye emva kokufakwa kwimveliso idlala indima ebalulekileyo kwimveliso kunye nokusebenza kwevalve.Ukulungiswa okuchanekileyo, okucwangcisiweyo kunye nokusebenzayo kuya kukhusela i-valve, yenza i-valve isebenze ngokuqhelekileyo kwaye yandise ubomi benkonzo yevalve.ubomi.Umsebenzi wokugcinwa kwevalve unokubonakala ulula, kodwa akunjalo.Kukho iinkalo ezininzi zomsebenzi ezingahoywayo.
1. Xa utofa igrisi kwivalve, ubungakanani benaliti yegrisi idla ngokungahoywa.Emva kokuba umpu wenaliti yegrisi ufakwe i-refueled, umqhubi ukhetha ivalve kunye nendlela yokudityaniswa kwenaliti yegrisi, aze enze umsebenzi wokutofa igrisi.Kukho iimeko ezimbini: kwelinye icala, inani lenaliti yegrisi lincinci kwaye inaliti yegrisi ayanelanga, kwaye umphezulu wokutywina unxiba ngokukhawuleza ngenxa yokungabikho kwe-lubricant.Kwelinye icala, isitofu segrisi esigqithisileyo sikhokelela kwinkcitho.Isizathu sikukuba akukho kubalwa komthamo wokutywina wevalve eyahlukileyo ngokodidi lwevalvu.Umthamo wokutywina unokubalwa ngokobungakanani bevalve kunye nohlobo, kwaye ke isixa esifanelekileyo segrisi sinokutofwa.
2. Xa i-valve ifakwe igrisi, ingxaki yoxinzelelo ihlala ingahoywa.Ngethuba lomsebenzi wokutofa igrisi, uxinzelelo lwenaliti yegrisi lutshintsha rhoqo ngeencopho kunye neentlambo.Uxinzelelo luphantsi kakhulu, itywina liyavuza okanye liyasilela, uxinzelelo luphezulu kakhulu, indawo yokutofa igrisi ivaliwe, igrisi yokutywina yangaphakathi yomelele, okanye iringi yokutywina itshixiwe ngebhola yevalve kunye nepleyiti yevalvu.Ngesiqhelo, xa uxinzelelo lwenaliti yegrisi lusezantsi kakhulu, igrisi etofwayo ikholisa ukuqukuqela ukuya kumazantsi omgodi wevalvu, oqhele ukwenzeka kwiivalvu zesango ezincinci.Ukuba uxinzelelo lwenaliti yegrisi luphezulu kakhulu, kwelinye icala, jonga umbhobho wenaliti yegrisi, kwaye uwubuyisele ukuba umngxuma wegrisi uvalekile..Ukongeza, uhlobo lokutywina kunye nezinto zokutywina nazo zichaphazela uxinzelelo lwenaliti yegrisi.Iindlela zokutywina ezahlukeneyo zineexinzelelo ezahlukeneyo zokutofa igrisi.Ngokubanzi, uxinzelelo lwenaliti yegrisi eqinileyo kufuneka ibe lelona tywina lithambileyo.
3. Xa ufaka igrisi kwivalve, nikela ingqalelo kwingxaki yokuba ivalve ikwindawo yokutshintsha.I-valve yebhola ngokuqhelekileyo ikwindawo evulekileyo ngexesha lokugcinwa, kwaye kwiimeko ezikhethekileyo, ikhethwa ukuba ivalwe ukugcinwa.Ezinye iivalve azinakuthatyathwa njengendawo evulekileyo.Ivalve yesango kufuneka ivalwe ngexesha lolondolozo ukuqinisekisa ukuba igrisi izalise igroove yokutywina ecaleni kweringi yokutywina.Ukuba ivuliwe, igrisi yokutywina iya kuwela ngqo kumjelo wokuhamba okanye umngxuma wevalvu, ibangele inkunkuma.
Okwesine, xa i-valve ifakwe igrisi, umphumo wenaliti yegrisi udla ngokungahoywa.Ngexesha lomsebenzi wokutofa igrisi, uxinzelelo, umthamo wenaliti yegrisi, kunye nendawo yokutshintsha zonke ziqhelekile.Nangona kunjalo, ukwenzela ukuba kuqinisekiswe umphumo we-grease injection ye-valve, ngamanye amaxesha kuyimfuneko ukuvula okanye ukuvala i-valve, ukujonga umphumo we-lubrication, kwaye uqinisekise ukuba umphezulu webhola ye-valve okanye i-plate yesango ixutywe ngokulinganayo.
5. Xa utofa igrisi, nikela ingqalelo kwingxaki ye-valve body drainage kunye ne-wire plugging pressure relief.Emva kovavanyo lokucinezela ivalve, irhasi kunye namanzi kumngxunya wevalve yecango lokutywina ziya kunyuswa ngenxa yokwanda kobushushu obukhoyo.Xa igrisi ijojowe, kuyimfuneko ukukhupha ukungcola kunye nokukhulula uxinzelelo, ukwenzela ukuba kube lula ukuqhubela phambili kwe-injection yegrisi.Umoya kunye nokufuma kwindawo evaliweyo kutshintshwa ngokupheleleyo emva kokutofa igrisi.Uxinzelelo lwe-valve cavity lukhutshwa ngexesha, eliqinisekisa nokhuseleko lwevalve.Emva kwenaliti yegrisi, qiniseka ukuba uqinise idreyini kunye neeplagi zokukhulula uxinzelelo ukukhusela iingozi.
6. Xa ufaka igrisi, nikela ingqalelo kwingxaki yegrisi efanayo.Ngexesha lokutofa okuqhelekileyo kwegrisi, umngxuma wokukhupha igrisi okufutshane nezibuko lokutofa igrisi uya kukhupha igrisi kuqala, emva koko iye kwindawo esezantsi, kwaye ekugqibeleni iye kwindawo ephezulu, kwaye igrisi iya kukhutshwa nganye nganye.Ukuba ayilandeli imigaqo okanye akukho nqatha, ibonisa ukuba kukho ukuvinjelwa, kwaye kufuneka ihlambuluke ngexesha.
7. Xa utofa igrisi, jonga kwakhona ukuba idiameter yevalve igungxulwa kunye nesitulo seringi yokutywina.Ngokomzekelo, kwi-valve yebhola, ukuba kukho ukuphazamiseka kwindawo yokuvula, lungisa umda wokuvula ngaphakathi ukuze uqinisekise ukuba ububanzi buchanekile kwaye uvale.Ukulungelelanisa umda akufanele kulandele indawo yokuvula okanye yokuvala kuphela, kodwa qwalasela yonke into.Ukuba indawo yokuvula i-flush kwaye indawo yokuvala ayikho, i-valve ayiyi kuvala ngokuqinileyo.Ngendlela efanayo, ukuba ukulungiswa kwendawo evaliweyo kusendaweni, ukulungiswa okuhambelanayo kwendawo evulekileyo kufuneka kuqwalaselwe.Qinisekisa ukuba ivalve ineengile efanelekileyo yokuhamba.
8. Emva kokutofa igrisi, qiniseka ukuba utywina indawo yokutofa igrisi.Ukuze ugweme ukungena kokungcola, okanye i-oxidation ye-lipids kwi-port injection yegrisi, isigqubuthelo kufuneka sigqunywe ngegrisi echasene ne-rust ukuphepha ukugqwala.ukwenzela umsebenzi olandelayo.
9. Xa ufaka igrisi, ingqwalasela kufuneka inikwe unyango oluthile lweengxaki ezithile ekuthuthweni okulandelelanayo kweemveliso zeoli kwixesha elizayo.Ukunikezelwa kweempawu ezahlukeneyo zedizili kunye nepetroli, i-scour kunye nokukwazi ukuhlukana kwepetroli kufuneka kuthathelwe ingqalelo.Kwixesha elizayo lomsebenzi we-valve, xa udibana nokusebenza kwecandelo lepetroli, igrisi kufuneka izaliswe kwakhona ngexesha lokuthintela ukuvela kokugqoka.
10. Xa utofa igrisi, musa ukuyihoya inaliti yegrisi kwisiqu sevalvu.Kukho i-sliding bushings okanye ukupakisha kwi-valve shaft, nayo kufuneka igcinwe i-lubricated ukunciphisa ukuxhatshazwa kwefriction ngexesha lokusebenza.Ukuba i-lubrication ayinakuqinisekiswa, i-torque iya kwandisa iindawo zokugqoka ngexesha lokusebenza kombane, kwaye ukutshintshwa kuya kuba nzima ngexesha lokusebenza ngesandla.
11. Ezinye iivalve zebhola ziphawulwe ngeentolo.Ukuba akukho mbhalo wesandla we-FIOW wesiNgesi, sisalathiso sesenzo sesihlalo sokutywina, kungekhona njengesalathiso sokuhamba komzila we-medium, kwaye isalathiso se-valve self-leakage ichasene.Ngokuqhelekileyo, iivalve zebhola ezihleli kabini zinokuhamba okuphindwe kabini.
12. Xa ugcina i-valve, kwakhona ubeke ingqalelo kwingxaki yokungena kwamanzi kwintloko yombane kunye nendlela yokuhambisa.Ingakumbi imvula engena ngexesha leemvula.Enye yeyokurusa isixhobo sothumelo okanye umkhono wothumelo, kwaye omnye kukukhenkceza ebusika.Xa i-valve yombane iqhutywe, i-torque inkulu kakhulu, kwaye umonakalo kwiindawo zokuhambisa ziya kwenza ukuba i-motor ingabikho umthwalo okanye uhambo oluphezulu lokukhusela i-torque, kwaye ukusebenza kombane akunakufezekiswa.Amalungu othumelo wonakaliswe, kwaye umsebenzi wezandla awukwazi ukwenziwa.Emva kwesenzo sokukhusela i-torque ephezulu, ukusebenza kwe-manual nako akukwazi ukutshintshela, njengokusebenza ngokunyanzeliswa, kuya kulimaza iindawo zangaphakathi ze-alloy.
Isishwankathelo, ukugcinwa kwevalve ngenene kunyangwa ngesimo sengqondo sesayensi, ukuze umsebenzi wogcino lwevalvu unokufikelela kwisiphumo sawo esifanelekileyo kunye nenjongo yokusetyenziswa.
