Iivalvu, njengezinye iimveliso zoomatshini, nazo zifuna ukulungiswa.Ukuba lo msebenzi wenziwe kakuhle, unokwandisa ubomi benkonzo yevalve.Oku kulandelayo kuya kwazisa ukugcinwa kwevalve.
1. Ukugcinwa kunye nokugcinwa kwevalvu
Injongo yokugcina kunye nokugcinwa akuyikonakalisa i-valve kwindawo yokugcina okanye ukunciphisa umgangatho.Enyanisweni, ukugcinwa okungafanelekanga sesinye sezizathu ezibalulekileyo zokulimala kwevalve.
Ukugcinwa kwevalve, kufuneka kube ngokufanelekileyo, iivalve ezincinci kwishelufu, iivalve ezinkulu zinokucwangciswa ngokucocekileyo kumhlaba wogcino, hayi imfumba engalungelelananga, ungavumeli umphezulu wonxibelelwano lweflange uqhagamshelane nomhlaba.Oku akukona nje ngenxa yezizathu zobuhle, kodwa ngokukodwa ukukhusela i-valve ekuqhekekeni.
Ngenxa yokugcinwa kunye nokuphathwa ngendlela engafanelekanga, ivili lesandla laphukile, i-valve stem igoso, ivili lesandla kunye ne-valve stem fixed nut ilahleko ekhululekile, njl., ezi lahleko zingeyomfuneko kufuneka ziphetshwe.
Kwiivalve ezingasetyenziswanga kwixesha elifutshane, iifayili ze-asbestos kufuneka zisuswe ukuze zigweme ukubola kwe-electrochemical kunye nomonakalo kwi-valve stem.
Iivalve ezisanda kungena kwindawo yokugcina impahla kufuneka zihlolwe.Umzekelo, amanzi emvula okanye ubumdaka obungena ngexesha lokuthuthwa kufuneka bosulwe kwaye bugcinwe.
I-inlet kunye ne-outlet yevalve kufuneka ivalwe ngephepha le-wax okanye i-plastiki sheet ukukhusela ukungcola ekungeneni.
Umphezulu wokusetyenzwa kwevalvu onokurusa emoyeni kufuneka uqatywe nge-oyile ye-antirust ukuwukhusela.
Iivalvu ezibekwe ngaphandle, kufuneka zogqunywe ngezinto ezingangenwa yimvula kunye nezinto ezingangenwa luthuli ezifana nelinoliyam okanye i-tarpaulin.Indawo yokugcina iivalve kufuneka igcinwe icocekile kwaye yomile.

2. Ukusebenza kunye nokugcinwa kwevalvu
Injongo yokusebenza kunye nokugcinwa kukwandisa ubomi be-valve kunye nokuqinisekisa ukuvulwa nokuvala okuthembekileyo.
I-valve stem thread, rhoqo kunye ne-valve stem nut friction, ukuba iqatywe ngeoli encinci etyheli eyomileyo, i-molybdenum disulfide okanye umgubo wegraphite, ukuthambisa.
Kwivalve engasoloko ivulwa kwaye ivaliwe, kuyafuneka ukuba ujikeleze rhoqo i-handwheel kwaye ungeze i-lubricant kwintambo ye-stem ukukhusela ukuluma.
Kwiivalve zangaphandle, umkhono okhuselayo kufuneka wongezwe kwi-valve stem ukukhusela imvula, ikhephu kunye nothuli.
Ukuba ivalve ngoomatshini yokulinda, kuyimfuneko yongeza ioyile yokuthambisa kwibhokisi yegiya ngexesha.
Gcina ivalve icocekile rhoqo.
Jonga rhoqo kwaye ugcine ingqibelelo yezinye iindawo zevalve.Ukuba i-nut esisigxina ye-handwheel iyawa, kufuneka ihambelane, ngaphandle koko iya kugawula amacala amane ommandla ophezulu we-valve stem, ngokuthe ngcembe ilahlekelwe ukuthembeka kokuhambelana, kwaye ingaphumeleli ukuqala.
Musa ukuthembela kwivalve ukuxhasa ezinye izinto ezinzima, musa ukuma kwivalve.
I-valve stem, ngokukodwa inxalenye yentambo, kufuneka isuswe rhoqo, kwaye i-lubricant engcoliswe luthuli kufuneka itshintshwe entsha, kuba uthuli luqulethe i-debris enzima, ekulula ukuyinxiba intambo kunye nomphezulu womhlaba. i-valve stem, echaphazela ubomi benkonzo.

3. Ukugcinwa kokupakishwa kwevalvu
Ukupakisha isitywina esibalulekileyo esihambelana ngokuthe ngqo nokuba ukuvuza kwenzeka xa ivalve ivuliwe kwaye ivaliwe, ukuba ukusilela kokupakisha, okubangela ukuvuza, ivalve ilingana nokusilela, ngakumbi ivalve yombhobho we-urea, kuba ubushushu bayo buphezulu. i-corrosion iphezulu, ukupakishwa kulula ukuguga.Ukomeleza ukugcinwa kunokwandisa ubomi bokupakisha.
Xa i-valve ishiya i-factory, ukwenzela ukuba kuqinisekiswe i-elasticity yokupakisha, ngokuqhelekileyo ixhomekeke kuvavanyo loxinzelelo lwe-static ngaphandle kokuvuza.Emva kokuba i-valve ilayishwe kumbhobho, ngenxa yeqondo lokushisa kunye nezinye izinto, kunokubakho i-seepage, ngoko kuyimfuneko ukuqinisa i-nut kumacala omabini e-gland yokupakisha ngexesha, ngokude nje ingaphumi, kwaye emva koko. i-seepage kwakhona, musa ukuqinisa kanye, ukwenzela ukuba ugweme ukulahlekelwa kwe-elasticity yokupakisha kunye nokulahlekelwa kokutywinwa kokusebenza.
Enye ivalve yokupakisha ixhotyiswe nge-molybdenum disulfide lubrication paste, xa isetyenziselwa iinyanga ezimbalwa, kufuneka ibe ngexesha elifanelekileyo ukongeza igrisi yokuthambisa ehambelanayo, xa kufunyaniswe ukuba i-filler kufuneka yongezwe, kufuneka kwangexesha inyuse ukupakisha okuhambelanayo, ukwenzela ukuqinisekisa ukusebenza kwayo kokutywinwa.

4. Ukugcinwa kweendawo zokuhanjiswa kwevalvu
I-valve kwinkqubo yokutshintsha, i-oyile yokuthambisa yasekuqaleni iya kuqhubeka ilahleka, idibene nendima yobushushu, ukubola kunye nezinye izinto, ziya kwenza ukuba ioyile yokuthambisa ihlale kwindawo eyomileyo.Ngoko ke, iindawo zokuhambisa i-valve kufuneka zihlolwe rhoqo, zifumanisa ukuba ukungabikho kweoli kufuneka kuzaliswe ngexesha, ukwenzela ukuthintela ukungabikho kwe-lubricant kunye nokwandisa ukunxiba, okubangelwa ukuhanjiswa okungenakuguquguquka kunye nokunye ukungaphumeleli.
umfanekiso we-4
Ukugcinwa kwe-valve kufuneka kuphathwe ngesimo sengqondo sesayensi, ukwenzela ukuba i-valve igcine umsebenzi wokufezekisa iziphumo ezifunwayo kunye neenjongo zokusetyenziswa.Ukuze wenze umsebenzi oqhelekileyo wemveliso, ukunciphisa ukupaka kunye nokwandisa inzuzo yezoqoqosho, kwivalve, kufuneka senze la manqaku mathathu:
Ukhetho oluchanekileyo lweevalvu sisiseko.
Ukusetyenziswa ngokufanelekileyo kwevalve ngundoqo.
Ukugcinwa okuchanekileyo sisiqinisekiso.
