1. Ukugcinwa kwevalve
Injongo yokugcina kunye nokugcinwa kukuthintela i-valve ukuba yonakaliswe okanye iyancipha umgangatho ngexesha lokugcinwa. Enyanisweni, ukugcinwa okungafanelekanga sesinye sezizathu ezibalulekileyo zokulimala kwevalve.
Ukugcinwa kwevalve, kufuneka kube ngokufanelekileyo, iivalve ezincinci kwishelufu, iivalve ezinkulu zinokubekwa ngokucocekileyo kumhlaba wogcino, hayi ngocwangco, ungavumeli umphezulu wonxibelelwano lweflange uqhagamshelane ngqo nomhlaba. Oku akukona nje i-aesthetics, kodwa kubaluleke ngakumbi ukukhusela i-valve ekonakalisweni. Ngenxa yokugcinwa okanye ukuphathwa ngendlela engafanelekanga, i-handwheel iphukile, i-valve stem igxiliwe, i-nut esisigxina ye-handwheel kunye ne-valve stem ikhululekile kwaye ilahlekile, njl., ezi lahleko ezingadingekile kufuneka zigwenywe.
Kwivalve engasetyenziswanga okwethutyana, ukupakishwa kwe-asbestos kufuneka kususwe ukuphepha ukubola kwe-electrochemical kunye nomonakalo kwisiqu.
Ivalve yokungena kunye ne-outlet kufuneka ivalwe ngephepha le-wax okanye iphepha leplastiki ukuthintela ukungena kwezinto ezingcolileyo ezichaphazela ivalve.
Ivalve inokugqwala kwi-atmosphere, kufuneka ifakwe ngeoli echasene ne-rust, ukukhusela, qaphela i-rust.
Iivalvu zangaphandle kufuneka zigqunywe ngezinto ezingangeni manzi nezingangenwa luthuli ezifana nelinoleum okanye itarp. Indawo yokugcina ivalve iya kugcinwa icocekile kwaye yomile.
Kufuneka igcinwe njani ivalve
2. Ukusetyenziswa kunye nokugcinwa kwevalvu
Injongo yokusetyenziswa kunye nokugcinwa kukwandisa ubomi benkonzo yevalve kunye nokuqinisekisa ukuvulwa nokuvala okuthembekileyo.
Imisonto yesiqu, edla ngokukhuhlana ne-stem nut, kufuneka iqatywe nge-oyile etyheli eyomileyo, i-molybdenum disulfide okanye umgubo wegraphite ukuze uthambise.
Ungadli ngokuvula kwaye uvale ivalve, kodwa kwakhona ukuguqula rhoqo ivili lesandla, yongeza i-lubricant kwintambo ye-stem, ukukhusela ukuluma.
Kwiivalve zangaphandle, imikhono yokukhusela kufuneka yongezwe kwi-valve stem ukukhusela imvula, ikhephu, uthuli kunye nomhlwa. Ukuba ivalve ngumatshini, yiba ngexesha kwi-gearbox thanda ioyile yokuthambisa.
Gcina ivalve icocekile.
Hlala unamathele kwaye ugcine ingqibelelo yecandelo levalvu. Ukuba i-nut emiselweyo ye-handwheel iyawa, kufuneka ihambelane kwaye ayikwazi ukusetyenziswa ngokufanelekileyo, ngaphandle koko iya kugaya isikwere esiphezulu se-valve stem, ngokuthe ngcembe ilahlekelwe ukuthembeka kwaye ingakwazi ukuqala.
Musa ukusebenzisa i-valve ukuthwala eminye imithwalo enzima, musa ukuma kwi-valve, njl
Isiqu, ngakumbi adelela inxalenye intambo, ngokufuthi zosula, i-lubricant iye yangcoliswa uthuli ukuba indawo entsha, kuba uthuli iqulethe inkunkuma isithunzi, lula ukunxiba intambo kunye nesiqu umphezulu, kuchaphazela ubomi benkonzo valve.
Ivalve esebenzayo kufuneka igcinwe kanye ngekota, kanye kwisiqingatha sonyaka emva kokuba iqalile ukusebenza, kanye ngonyaka emva kokuba iqalile ukusebenza, kwaye ivalve kufuneka igcinwe phambi kobusika minyaka yonke. Yenza umsebenzi wevalve oguquguqukayo kunye nokuvuthela kanye ngenyanga.
3. Ukugcinwa kokupakisha
Ukupakisha kuhambelana ngokuthe ngqo nokuba ukuvuza kwenzeka xa i-valve ivuliwe kwaye ivala iindawo eziphambili zokutywinwa, ukuba ukupakisha kusilela, okubangele ukuvuza, i-valve ilingana nokusilela, ngakumbi i-valve yombhobho we-urea, kuba ubushushu bayo buphezulu. ngoko ke i-corrosion inzima kakhulu, ukupakishwa kulula ukuguga. Ukomeleza ukugcinwa kunokwandisa ubomi bokupakisha.
Xa i-valve ishiya i-factory, ngenxa yeqondo lokushisa kunye nezinye izinto, kunokubakho i-extravasation, ngoko ke kuyimfuneko ukuqinisa i-nut kumacala omabini e-gland yokupakisha ngexesha, ngokude nje ingavuzi, kwaye emva koko qinisa kwakhona. imeko ye-extravasation, musa ukuqinisa kanye, ukuze ungalahlekelwa ukuguquguquka kokupakisha kunye nokulahlekelwa kokutywinwa kokusebenza.
Enye ivalve yokupakisha kunye ne-molybdenum dioxide lubrication paste, xa isetyenziswe kwiinyanga ezimbalwa, kufuneka ifakwe kwigrisi yokuthambisa ehambelanayo ngexesha, xa kufunyaniswa ukuba ukupakisha kufuneka kuncediswe, kufuneka kufakwe kwi-packing ehambelanayo ngexesha lokuqinisekisa. umsebenzi wokutywinwa.
4. Ukugcinwa kwamacandelo othumelo
I-valve kwinkqubo yokutshintsha, i-oyile yokuthambisa yasekuqaleni iya kuqhubeka ilahleka, idibene nobushushu, ukubola kunye nezinye iziphumo, nayo iya kwenza ukuba ioyile yokuthambisa ihlale isomile. Ngoko ke, inxalenye yokudluliselwa kwe-valve kufuneka ihlolwe rhoqo, ifunyaniswe ukuba ifanele izaliswe ngexesha elifanelekileyo, qaphela ukunyuka kokugqoka ngenxa yokungabikho kwe-lubricant, okubangelwa ukuhanjiswa okungaguqukiyo okanye ukungaphumeleli kwe-jam kunye nezinye iimpazamo.
5. Ukugcinwa kwenaliti yegrisi yevalvu
Xa ivalve ithambisa, ingxaki yobungakanani begrisi idla ngokungahoywa. Emva kokuba i-valve ifakwe igrisi, umqhubi ukhetha indlela yokudibanisa yevalve kunye negrisi ukuze aqhube umsebenzi wegrisi. Kukho iimeko ezimbini: kwelinye icala, inaliti encinci yamafutha ikhokelela kwinaliti yamafutha angonelanga, kwaye umphezulu wokutywina ukhawuleza ukunxiba ngenxa yokunqongophala kwesithambiso. Kwelinye icala, inaliti yamafutha agqithisileyo, okukhokelela kwinkcitho. Akukho lubalo luchanekileyo lweendlela ezahlukeneyo zokutywina zevalve ngokusekelwe kuhlobo lwevalvu kunye nodidi. Umthamo wokutywina unokubalwa ngobungakanani bevalvu kunye nohlobo, kunye nenaliti efanelekileyo yegrisi efanelekileyo.
Iingxaki zoxinzelelo zihlala zingahoywa kwisitofu segrisi yevalvu. Kwinkqubo ye-fat injection, uxinzelelo lwe-fat injection lunencopho eqhelekileyo kunye nokuguqulwa kwentlambo. Ukuba uxinzelelo lusezantsi kakhulu, ukuvuza kwetywina okanye ukusilela, ukuba uxinzelelo luphezulu kakhulu, izibuko lokutofa igrisi livalekile, kunye necherry yegrisi okanye iringi yokutywina kwitywina itshixiwe ngebhola yevalve kunye nepleyiti yevalvu. Ngesiqhelo, xa uxinzelelo lwenaliti yegrisi lusezantsi kakhulu, igrisi etofiweyo iqukuqela ezantsi kwegumbi levalvu, eyenzeka ngokubanzi kwiivalvu zesango ezincinci. Ukuba uxinzelelo lwenaliti yegrisi luphezulu kakhulu, kwelinye icala, jonga umbhobho wenaliti yegrisi kwaye uwubuyisele endaweni ukuba kuchongiwe ukuvaleka komngxuma wamafutha. Kwelinye icala, igrisi iyaqina. Ulwelo lokucoca kufuneka lusetyenziselwe ukuthambisa igrisi yokutywina engaphumelelanga ngokuphindaphindiweyo kunye nokutofa igrisi entsha ukuyibuyisela endaweni yayo. Ukongeza, uhlobo lokutywina kunye nezixhobo zokutywina zikwachaphazela uxinzelelo lwenaliti yegrisi, iindlela zokutywina ezahlukeneyo zinexinzelelo loxinzelelo lwenaliti yegrisi, ngokubanzi, uxinzelelo lwenaliti yegrisi elukhuni luphezulu kunophawu oluthambileyo.
Xa uthambisa i-valve, nikela ingqalelo kwingxaki yendawo yokutshintsha i-valve. Ukugcinwa kwevalve yebhola ngokuqhelekileyo kwindawo evulekileyo, iimeko ezikhethekileyo zikhetha ukuvala ukulungiswa. Ezinye iivalve akufuneki zivuleke. Ivalve yesango ekugcinweni kwayo kufuneka ibekwimeko evaliweyo, qinisekisa ukuba igrisi ecaleni kweringi yokutywina igcwele igroove yokutywina. Ukuba ivuliwe, igrisi yokutywina ngokuthe ngqo kwindawo yokuhamba okanye yevalvu, okukhokelela kwinkunkuma.
Isiphumo sesitofu segrisi yevalve sihlala singahoywa. Uxinzelelo, isixa samafutha kunye nendawo yokutshintsha zonke ziqhelekile ekusebenzeni kwesitofu samafutha. Nangona kunjalo, ukwenzela ukuba kuqinisekiswe i-valve grease effect, ngamanye amaxesha kuyimfuneko ukuvula okanye ukuvala i-valve, khangela i-lubrication effect, uqinisekise ibhola yevalve okanye i-lubrication surface yesango ifana.
Xa inaliti yegrisi, ingqwalasela kufuneka ihlawulwe kugutyulo logutyulo lomzimba wevalve kunye neengxaki zokuvala uxinzelelo lwesilika. Emva kovavanyo loxinzelelo lwevalve, igesi kunye namanzi kwigumbi elivaliweyo levalve liya kwandisa uxinzelelo ngenxa yokwanda kobushushu obuphantsi, kwaye ukunyanzeliswa koxinzelelo lokukhutshwa kwamanzi amdaka kufuneka kuqhutywe kuqala ukuququzelela ukusebenza kakuhle kwenaliti yegrisi. Emva kwesitofu segrisi, umoya kunye nokufuma kwindawo evaliweyo kuyasuswa ngokupheleleyo. Uxinzelelo lwegumbi lokukhutshwa ngexesha elifanelekileyo, kodwa nokuqinisekisa ukhuseleko lokusetyenziswa kwevalve. Emva kwesitofu segrisi, umsele kunye nocingo lokukhulula uxinzelelo kufuneka luqiniswe ukunqanda ukwenzeka kweengozi.
Inaliti yegrisi kufuneka kwakhona iqwalasele idiamitha yevalvu kunye nengxaki yokutywina yesitulo sokugungxula. Ngokomzekelo, i-valve yebhola, ukuba kukho ukuphazamiseka, unokulungelelanisa umda wokuvula ngaphakathi, uqinisekise ukuba ububanzi buchanekile emva kwelanga. Lungisa umda akanakulandela kuphela okanye uvale isikhundla, ukuqwalasela yonke into. Ukuba indawo yokuvula ilingana kwaye ukuvala akukho ndawo, i-valve iya kuvalwa ngokukhululekile. Ngokufanayo, lungisa utshintsho kwindawo, kwaye uqwalasele ukulungiswa okuhambelanayo kwendawo evulekileyo. Qinisekisa i-engile ekunene isibetho sevalvu.
Emva kokutofa igrisi, qiniseka ukuba ulitywina inani lenaliti yomlomo wegrisi. Kuphephe ukungcola kwi-oxidation yegrisi yomlomo, ukugquma ukuthambisa igrisi echasene nomhlwa, ukunqanda umhlwa. Kumsebenzi olandelayo.
I-valve ye-actuator yombane yesikhululo samandla yaziswa indawo ebonisa isixhobo (3) itshekhi, ii-activators zombane zifakwe kwibhentshi yovavanyo, isalathisi sendawo yevalvu yesalathisi kwindawo "ehleliyo", akukho mthwalo uqalisa i-actuator zombane, khangela isalathisi kunye nesiphumo. ukujikeleza kwe-shaft, xa ummiselo wokufikelela kwiindawo ezininzi "ezivulekileyo" (ezifana nevalve), Inkqubo yokujikeleza kunye nendawo yesalathisi iya kuhambelana nezibonelelo ze-5.2. 10, kwaye inani leemvavanyo aliyi kuba ngaphantsi kwamaxesha amathathu. Uvavanyo lwentsebenzo yokhuselo lwe-enclosure luya kwenziwa ngokuhambelana ne-GB 4208 kwaye iziphumo ziya kuhambelana ne-6.1.2.
