Ulungiso lweValve yemihla ngemihla
I-1. I-valve kufuneka igcinwe kwindawo eyomileyo nenezakhono, kwaye zombini iziphelo zendinyana kufuneka ivaliwe.
2. IiValves ezigcinwe ixesha elide kufuneka zitshekishwe rhoqo, ubumdaka kufuneka zisuswe, kwaye ioyile ye-anti-rusts kufuneka isetyenziswe kwindawo yokulungisa.
I-3. Emva kokufakwa, ukuhlolwa rhoqo kufuneka kwenziwe. Izinto eziphambili zokuhlola:
(1) Ukunxiba komhlaba wokutywina.
.
(3) ingaba ukupakisha kuphelelwe lixesha kwaye kungasebenzi, ukuba yonakele, kufuneka itshintshwe ngexesha.
(4) Emva kweManyano ye-UnionI-Palve Valve X9201-TI-grey igqithe kwaye ihlanganisene, uvavanyo lwendlela yokutywina kufuneka lwenziwe.
Umsebenzi wesondlo ngexesha le-valve grikection
Umsebenzi wokugcina ivali ngaphambi kokuba i-welding kwaye emva kokuba ifakwe kwimveliso idlala indima ebalulekileyo kwimveliso nokusebenza kwevali. Ulondolozo oluchanekileyo, olucwangcisiweyo kunye nolungelelwano luya kukhusela ivalve, yenza iveli iqhele kwaye iqale ubomi benkonzo yevalve. Ubomi. Umsebenzi wokulungisa i-valve usenokubonakala ngathi ulula, kodwa akunjalo. Kuhlala kukhona inkalo yomsebenzi.
1. Xa irhawula igrisi kwivali, isixa senaliti yegrisi ihlala ingahoywa. Emva kokuba inaliti ye-Guection Fining iKhuthile, umqhubi ukhetha i-valve kunye nejele yoqhagamshelo lwentsholongwane, emva koko wenza umsebenzi wentsholongwane. Kukho iimeko ezimbini: Kwelinye icala, isixa senaliti yegrisi sincinci kwaye inaliti yegrisi ayonelanga, kwaye umphezulu wokutywina unxiba ngokukhawuleza ngenxa yokunqongophala ngenxa yokunqongophala kwendawo ye-oyile. Kwelinye icala, inja egqithisileyo inamafutha. Isizathu kukuba akukho lubalo lwe-valve ezahlukeneyo lokomelela ngokodidi lweValve. Isithuba sokutywina singabalwa ngokwesakhiwo se-veli kunye nohlobo, kwaye ke isixa esifanelekileyo segrisi sinokutshiswa.
2. Xa ivalve igcwele, ingxaki yoxinzelelo ihlala ingahoywa. Ngexesha lokusebenza kwentsholongwane, uxinzelelo lwentshukumo yoxinzelelo luguquka rhoqo ngeincopho kunye neentlambo. Ingcinezelo iphantsi kakhulu, itywina okanye itywina okanye ingcinezelo iphakame kakhulu, i-port yensundus ivinjelwe, okanye iringi yangaphakathi itshixiwe kwibhola ye-valve kunye neplate ye-valve. Ngokwesiqhelo, xa uxinzelelo lwentsholongwane lusezantsi kakhulu, igrisi engafunekiyo ihamba emazantsi evalini, edla ngokwenzeka ngamava amancinci esango. Ukuba uxinzelelo lwentsholongwane luphezulu kakhulu, kwelinye icala, jonga i-greses intshi, kwaye uyitshintshe ukuba umngxunya wegrisi uvaliwe. . Ukongeza, uhlobo lokutywina kunye nezinto zokutywina zikwachaphazela uxinzelelo lwengqokelela yegrisi. Iifom zokutywina ezahlukeneyo zinezitolo ezahlukeneyo zetoti. Ngokubanzi, itywina elinzima lokutsala i-Greats Inaliti yoxinzelelo kufuneka ibe yeyona tywina elithambileyo.
3. Xa irhabaxa igrisi kwi-valve, inikele ingqalelo kwingxaki yokuba ivalve ikwisikhundla sokutshintsha. Ivalve yebhola ihlala ikwindawo evulekileyo ngexesha lokulungiswa, kwaye kwiimeko ezizodwa, ikhethiwe ukuba ivalelwe isondlo. Ezinye iivalves azinakuthathwa njengendawo evulekileyo. I-Valve yeSango kufuneka ivaliwe ngexesha lolondolozo ukuqinisekisa ukuba i-greose igcwalisa i-roove etyhidiweyo. Ukuba ivuliwe, igrisi yokutywina iya kuwa ngqo kwijelo lokuhamba okanye i-valve cavity, ibangela inkunkuma.
Okwesine, xa ivalve ithatyathwa, ifuthe legrisi ihlala ingahoywa. Ngexesha lokusebenza kwentsholongwane, uxinzelelo, i-greymes yenaliti, kunye nendawo yokutshintshela yonke iqhelekileyo. Nangona kunjalo, ukuze kuqinisekiswe ukuba isiphumo sentiyo yegwina, ngamanye amaxesha kufuneka ukuba ivule okanye ivale i-valve, jonga isiphumo se-qubriceation, kwaye uqinisekise ukuba umphezulu webhotile ye-valve okanye iplate yesango inyibilikile.
I-5. Xa itoti yokutshintsha i-Grease, nikela ingqalelo kwingxaki ye-valionage yomzimba kunye nocingo lwe-wire lwe-wire lwe-wire. Emva kovavanyo lokucinezela i-valve, irhasi kunye namanzi kwindawo ye-valve ye-vality ye-cavity iya kuphakanyiswa ngenxa yokwanda kobushushu obufanelekileyo. Xa igrisi itotshwa, iyimfuneko ekukhupheleni amanzi amdaka kwaye ikhuphe uxinzelelo, ukwenzela ukuqhuba inkqubela phambili egudileyo yenaliti yegrisi. Umoya kunye nomswakama kwi-cavity etywiniweyo itshintshwe ngokupheleleyo emva kwenzwane. Ingcinezelo ye-valve ye-valve ikhutshwa ngexesha, eqinisekisa ukhuseleko lwevalve. Emva kwenaliti yegrisi, qiniseka ukuba uqinisa i-Drain kunye neeplagi zoncedo zokunceda ukunqanda iingozi.
I-6. Xa itoti yokutshintsha i-Grease, nikela ingqalelo kwingxaki yegrisi efanayo. Ngexesha lenyoka eqhelekileyo, i-grey yokukhupha umngxunya ekufutshane nezibuko zethayile ziya kukhutshwa kwigrisi yokuqala, kwaye ekugqibeleni ukuya kwinqanaba elinye. Ukuba ayilandeli imigaqo okanye akukho nqatha, kuyangqina ukuba kukho ibhloko, kwaye kufuneka icocwe emva kwexesha.
7. Xa itoti yokutshintsha i-Gease, ikwajonga ukuba i-valve idutyulwe sisihlalo sokutywina. Umzekelo, kwivalve yebhola, ukuba kukho ukuphazamiseka kwindawo yokuvula, lungisa umda wokuvula ngaphakathi ukuze uqinisekiswe ukuba ububanzi buthi ngqo kwaye emva koko batshixe. Ukulungelelanisa umda akufuneki kulandelwe kuphela indawo yokuvula okanye yokuvala, kodwa qwalasela iyonke. Ukuba indawo yokuvula iyagungxulwa kwaye indawo yokuvala ayikho, ivalve ayiyi kuvalwa ngokuqinileyo. Ngendlela efanayo, ukuba uhlengahlengiso lwendawo evaliweyo yindawo, uhlengahlengiso oluhambelanayo lwendawo evulekileyo nayo kufuneka ithathelwe ingqalelo. Qiniseka ukuba ivalve ine-angle elungileyo yokuhamba.
I-8. Emva kwenaliti yenqaba, qiniseka ukuba itywina i-port yegrisi. Ukuthintela ukungena kwempahla, okanye i-oxids ye-lipids kwina yezibuko zegrisi, ikhava kufuneka idityaniswe negrisi ye-anti-rust ukuphepha ukuthoba. Umsebenzi olandelayo.
9. Xa itori yokuthambisa, kufuneka iqwalaselwe kuthathelwe ingqalelo kunyango oluthile lweengxaki ezithile kuhambo olulandelelanayo lokuthuthwa kweemveliso zeoyile kwixa elizayo. Ngenxa yeempawu ezahlukeneyo zedizili kunye ne-petroli, amandla e-chier kunye ne-dirinteration yepetroli kufuneka ithathelwe ingqalelo. Kwintsebenziswano ye-vulve yexesha elizayo, xa udibana nemisebenzi yecandelo le-petroli, igrisi kufuneka iphinde iphinde iphinde iphinde iphinde iphinde iphinde ithintele ukunxiba.
I-10. Xa i-Geing Grease, sukuyityeshela inaliti yegrisi kwi-valve stem. Kukho i-sking bushshings okanye ukupakisha kwi-chall ye-vall, ekufuneka igcinwe igcinwe inyibilikisiwe ukunciphisa ukunganyangeki kwemali ngexesha lokusebenza. Ukuba i-oyile ayinakuqinisekiswa, itotalo iyakonyusa iinxalenye zalo mpahla ngexesha mali, kwaye utshintsho luya kuba nzima ngexesha lokusebenza.
11. Ezinye iivali zebhola ziphawulwe ngeentolo. Ukuba akukho mbhalo we-fiow e-Fow fiow, luhlobo lwesenzo sesenzo esihlekisayo, hayi njengesalathiso sokuhamba kwendlela, kwaye indlela ye-valve yokuzivuza iyaphikisana. Ngokwesiqhelo, i-valve yebhola ephindwe kabini ihamba i-vidirectial flow.
12. Xa ugcina ivalve, nevalikeni kwingxaki yokufakelwa kwamanzi kwintloko yombane kunye nendlela yayo yothungelwano. Ngakumbi imvula efuna imvula ngexesha lemvula. Enye yeyokugqobhoza indlela yokuhambisa okanye umkhono wokuhambisa, kwaye enye iyanda ebusika. Xa i-valve yombane isebenza, itotar inkulu kakhulu, kwaye umonakalo wezinto zokuhambisa uyakwenza umthwalo ongekho mthethweni okanye olona hambo loKhuseleko lweTorque, kwaye umsebenzi wombane awunakufezekiswa. Iinxalenye zothungelwano zonakalisiwe, kwaye utyalo lwencwadi ayinakuqhutywa. Emva kwento ephezulu yokukhusela i-Terque, umsebenzi wencwadi ayikwazanga ukutshintsha, njengokusebenza ngokunyanzelwa, kuya kuyonakalisa indawo yangaphakathi.
Kwisishwankathelo, ulondolozo lwe-valve luphathwa ngenene ngesimo sesayensi, ukuze umsebenzi wevali anokufezekisa ukusebenza kwayo kunye nenjongo yesicelo.
